Directions in Library Networking

Avram, H.D.
McCallum, S.H.
.W
    Bibliographic control before and after MARC is reviewed.  The capability
of keying into online systems brought an interdependence among libraries,
the service centers that mediate between them, and the large utilities that
process and distribute data.  From this has developed the basic network
structure among libraries in the United States.  The independent development
of major networks has brought problems in standardization and coordination.
The authors point out that while technology has led toward centralization
of automated library services, new developments are now pushing toward 
decentralization.  Coordination is a requirement to avoid fragmentation in
this new environment.

Performance Testing of a Book and Its Index as a Information Retrieval
System
.A
Bennion, B.C.
.W
    The retrieval performance of book indexes can be measured in terms of
their ability to direct a user selectively to text material whose identity
but not location is known.  The method requires human searchers to base
their searching strategies on actual passages from the book rather than on
test queries, natural or contrived.  It circumvents the need for relevance
judgement, but still yields performance indicators that correspond 
approximately to the recall and precision ratios of large document retrieval
system evaluation.  A preliminary application of the method to the subject
indexing of two major encyclopedias showed one encyclopedia apparently 
superior in both the finding and discrimination abilities of retrieval
performance.  The method is presently best suited for comparative testing
since its ability to yield absolute or reproducible measures is as yet not
established.

The Combined Use of Bibliographic Coupling and Cocitation for Document
Retrieval
.A
Bichteler, J.
Eaton, E.A. III
.W
    A linkage similarity measure which takes into account both the bibliographic
coupling of documents and their cocitations (both cited and citing papers)
produced improved document retrieval over a measure based only on
bibliographic coupling.  The test collection consisted of 1712 papers whose
relevance to specific queries had been judged by users.  To evaluate the
effect of using cocitation data, we calculated for each query two measures
of similarity between each relevant paper and every other paper retrieved.
Papers were then sorted by the similarity measures, producing two ordered
lists.  We then compared the resulting predictions of relevance, partial
relevance, and non-relevance to the user's evaluations of the same papers.
Overall, the change from the bibliographic coupling measure to the linkage
similarity measure, representing the introduction of cocitation data,
resulted in better retrieval performance.

    The way that individuals construct and modify search queries on a
large interactive document retrieval system is subject to systematic biases
similar to those that have been demonstrated in experiments on judgements
under uncertainty.  These biases are shared by both naive and sophisticated
subjects and cause the inquirer searching for documents on a large interactive
system to construct and modify queries inefficiently.  A searching algorithm
is suggested that helps the inquirer to avoid the effect of these biases.

    This article concerns the problem of how to permit a patron to

request while retaining the desirable properties of a Boolean system.
The character of classical Boolean systems is reviewed and related to the
notion of fuzzy sets.  The fuzzy set concept then forms the basis of the
concept of a fuzzy request in which weights are assigned to index terms.
Ther properties of such a system are discussed, and it is shown that such
systems retain the manipulability of traditional Boolean requests.

Feature Comparison of an In-House Information Retrieval System With a
Commercial Search Service
.A
Boyle, S.O.
Miller, A.P.
.W
    A commercially available online search was used as a standard for
comparative searching and evaluation of an in-house information system
based on automatic indexing.  System features were identified and
evaluated on the basis of their usefulness in various kinds of searching,
their ease in implementation, and how they are influenced by differences
in user type or specific applications.  Some common features of the
commercial system, such as online instruction, user-specified print formats,
dictionary display, and truncation, are seen to be unnecessary or
impractical for the in-house system.  In designing the in-house system,
therefore, detald consideration must be given to the applications,
operating environment, and real user needs.  While a commercial system can
serve as a useful standard for comparative evaluation, one must be
careful not to attempt to duplicate it blindly in-house.

easily made once the two spaces are distinguished.  If the transformations

    The use of document clusters has been suggested as an efficient file
organization for a document retrieval system.  It is possible that by
using this information about the relationships between documents that the
effectiveness of the system (i.e., its ability to distinguish relevant
from non-relevant documents) may also be improved.  In this paper a
probabilistic model of cluster searching  based on query classification is
described.  This model is tested with retrieval experiments which indicate
that it can be more effective than heuristic cluster searches and cluster 
searches based on other models.  It can also be more effective than a full
search in which every document is compared to the query.  The efficiency
aspects of the implementation of the model are discussed.

The Use of Titles for Automatic Document Classification
.A
Hamill, K.A.
Zamora, A.
.W
    An experimental computer program has been developed to classify
documents according to the 80 sections and five major section groupings of
Chemical Abstracts (CA).  The program uses pattern recognition techniques
supplemented by heuristics.  During the "training" phase, words from 
pre-classified documents are selected, and the probability of occurrence
of each word in each section of CA is computed and stored in a reference
dictionary.  The "classification" phase matches each word of a document
title against the dictionary and assigns a section number to the document
using weights derived from the probabilities in the dictionary.  Heuristic
techniques are used to normalize word variants such as plurals, past
tenses, and gerunds in both the training phase and the classification
phase.  The dictionary lookup technique is supplemented by the analysis of
chemical nomenclature terms into their component word roots to influence
the section to which the documents are assigned.  Program performance and
human consistency have been evaluated by comparing the program results
against the published sections of CA and by conducting an experiment with
people experienced in the assignment of documents to CA sections.  The
program assigned approximately 78% of the documents to the correct major
section groupings of CA and 67% of the correct sections or cross-references
at a rate of 100 documents per second.

Brief Communications
.A
Harding, A.G.
Willett, P.
.W
    Some of the automatic classification procedures used in information
retrieval derive clusters of documents from an intermediate similarity
matrix, the computation of which involves comparing each of the documents
in the collection with all of the others.  It has recently been suggested
that many of these comparisons, specifically those between documents
having no terms in common, may be avoided by means of the uyse of an inverted
file to the document collection.  This communication shows that the
approach will effect reductions in the number of interdocument comparisons
only if the documents are each indexed by a limited number of indexing
terms; if exhaustive indexing is used, many document pairs will be compared
several times over and the computation will be greater than when
conventional approaches are used to generate the similarity matrix.

eases the process of grouping terms into files of similar concepts and
facilitates the generation of products useful in vocabulary review and in
term structuring.  Syndetic relations, indicated by assigning coded
identification numbers, are altered easily in the design phase to reflect
restructuring requirements.  Because thesaurus terms are already in machine-
readable form, it is simple to prepare print programs to provide permuted,
alphabetic, hierarchical, and chart formatted term displays.  Overall, the
use of the minicomputer facilitates initial thesaurus entry development by
reducing clerical effort, editorial staff decisions, and overall processing

Adaptive Design for Decision Support Systems
.A
Keen, P.G.W.
.W
    Decision Support Systems (DSS) represent a concept of the role of
computers within the decision making process.  The term has become a
rallying cry for researchers, practitioners, and managers concerned that
Management Science and Management Information Systems fields have become
unnecessarily narrow in focus.  As with many rallying cries, the term is
not well defined.  For some writers, DSS simply mean interactive systems
for use by managers.  To others, the key issue is support, rather than
system.  They focus on understanding and improving the decision process;
a DSS is then designed using any available and suitable technology. Some
researchers view DSS as a subfield of MIS, while others regard it as an
extension of Management Science techniques.  The former define Decision
Support as providing managers with access to data and the latter as giving
them access to analytic models.

    The key argument of this paper is that the term DSS is relevant to 
situations where a "final" system can be developed only through an
adaptive process of learning and evolution.  The design strategy must
then focus on getting finished; this is very different from Management
Science and Data Processing approaches.  The research issued for DSS
center around adaption and evolution; they include managerial learning
representation of tasks and user behavior, design architecture and
strategies for getting started.

An Automatic Method for Extracting Significant

    A new method is described to extract significant phrases in the title
and the abstreact of scientific or technical documents.  The method is
based upon a text structure analysis and uses a relatively small dictionary.
The dictionary has been constructed based on the knowledge about concepts
in the field of science or technology and some lexical knowledge.  For
significant phrases and their component items may be used in different
meanings among the fields.  A text analysius approach has been applied to
select significant phrases as substantial and semantic information carriers
of the contents of the abstract.

    The results of the experiment for five sets of documents have shown
that the significant phrases are effectively extracted in all cases, and
the number of them for every document and the processing time is fairly
satisfactory.  The information representation of the document, partly
using the method, is discussed with relation to the construction of the
document information retrieval system.

    Passage retrieval (already operational for lawyers) has advantages in

Previous experiments in passage retrieval for scientists have demonstrated
recall and false retrieval rates as good or better than those of present

variety of forms of retrieval question.  In addition, search words were
selected independently by two different people for each retrieval question.
The search words selected, in combination with the computer procedures used
for passage retrieval, produced average recall ratios of 72 and 67%,
respectively, for the two selectors.  The false retrieval rates were (except
for one predictably difficult question) respectively 13 and 10 falsely
retrieved sentences per answer-paper retrieved.

Partial-Match Retrieval Using Indexed Descriptor Files

    In this paper we describe a practical method of partial-match retrieval
in very large data files.  A binary code word, called a descriptor, is
associated with each record of the file.  These record descriptors are
then used to form a derived descriptor for a block of several records,
which will serve as an index for the block as a whole; hence, the name
"indexed descriptor files."

    First the structure of these files is described and a simple, efficient
retrieval algorithm is presented.  Then its expected behavior, in terms of
storage accesses, is analyzed in detail.  Two different file creation
procedures are sketched, and a number of ways in which the file organization
can be "tuned" to a particular application is suggested.

    This paper presents a method of normalizations of English titles and
their retrieval.  The title expressed by a noun phrase or a noun clause
is converted to a function-expression by parsing.  For the retrieval with
a reasonable recall rate as well as a high precision rate, the function-
expression is transformed to a predicate-governor form, and then normalized
to a standard form.  Therefrom, various items are extracted and recorded
in a hierarchical tree-like inverted file.

    In order to keep the recall rate in a reasonable value, several
retrieval stages are implemented based on the key-term and case-label
matching.  The retrieval is controlled by the preciseness of the specification
of case-labels for each key-term.

Cascaded ATN Grammars
.A
Woods, W.A.
.W
    A generalization of the notion of ATN grammar, called a cascaded ATN
(CATN), is prescribed.  CATN's permit a decomposition of complex language
understanding behavior into a sequence of cooperating ATN's with separate
domain of responsibility, where each stage (called an ATN transducer)
takes its input from the output of the previous stage.  The paper includes
an extensive discjussion of the principles of factoring-conceptual
factoring reduces the number of places that a given fact needs to be
represented in a grammar, and hypothesis factoring reduces the number
of distinct hypotheses that have to be considered during parsing.

    Algorithms are given to process partially specified queries in a

queries that use either whole words or word fragments as language elements.
The methods are compared and critically evaluated in terms of the design

interdependence of fragments as well as the relevance of fragments to
records in the file has maximum design cost and least retrieval cost.

A General Formulation of Bradford's Distribution:  The Graph-Oriented 
Approach
.A
Asai, I.
.W
    From the detailed analysis of eight previously published mathematical
models, a general formulation of Bradford's distribution can be deduced as
follows:  y = a log(x + c) + b, where y is the ratio of the cumulative
frequency of articles to the total number of articles and x is the ratio
of the rank of journals to the total number of journals.  The parameters a, b,
and c are the slope, the intercept, and the shift in a straight line to log rank,
respectively.  Each of the eight models is a special case of the general
formulation and is one of five types of formulation.  In order to estimate
three unknown parameters, a statistical method using root-weighted square
error is proposed.  A comparative experiment using 11 databases suggests that
the fifth type of formulation with three unknown parameters is the best fit
to the observed data.  A further experiment shows that the deletion of the
droop data leads to a more accurate value of parameters and less error.

Lexical Problems in Large Distributed Information Systems
.A
Berkovich, S.Y.
Shneiderman, B.
.W
    The lexical problems in large information systems are created by the
necessity of handling a great number of names and their interrelations.
Such lexical problems are not covered completely by the concept data
dictionaries, which are mostly concerned with database scheme design rather
than the execution of operations.  In this paper we introduce our view of a
lexical subsystem as a separate component in an information system architecture,
to deal with linguistic and control functions concerning the lexical problems
in local and network environments.  The lexical suybsystem is a special
efficiently organized program package, which plays the role of a "linguistic
filter" in a broad sense for lexically incorrect queries, promotes integration
of databases and information retrieval systems, and facilitates the creation
of local information systems.  We hope that lexical subsystems can become
productive for any large, especially distributed, information system.

Numerous examples pertinent to information retrieval are presented in these

Specifically described is a document distribution architecture and its
associated data streams and others.

    A general overview of the architectures as opposed to a detailed
technical description is provided.  The architectures described are
protocols for interchange between application processes; they do not
address the specific user interface.  The document distribution

The Use of Automatic Relevance Feedback in Boolean Retrieval Systems

    A technique is described for automatic reformulation of boolean
queries.  Based on patron relevance judgements of an initial retrieval,
prevalence measures are derived for terms appearing in the retrieved set
of documents that reflect a term's distribution among the relevant and
non-relevant documents.  These measures are then used to guide the
construction of a boolean query for a subsequent retrieval.  To illustrate
the technique, a series of tests is described of its application to a small
data base in an experimental environment.  Results compare favourably with
feedback as employed in a SMART-type system.  MOre extensive testing is
suggested to validate the technique.

Interacting in Natural Language With Artificial Systems:  The Donau Project

Somalvico, M.
.W
    This paper is intended to propose a new methodological approach to
the conception and development of natural language understanding systems.
This new contribution is supported by the design, implementation, and
experimentation of DONAU:  a general purpose domain oriented natural
language understanding system developed and presently running at the Milan
Polytechnic Artificial Intelligence Project.  The system is based on a two
level modular architecture intended to overcome the lack of flexibility and
generality often pointed out in many existing systems, and to facilitate
the exchange of results and actual experiences between different projects.
The horizontal level allows an independent and parallel development of the
single segments of the system (syntactic analyser, information extractor,
legality controller).  The vertical level ensures the possibility of changing
(enlarging or redefining) the definition of the semantic domain on which each
particular version of the system is oriented and specialized in a simple,
incremental, and user-oriented way.  In the paper the general architecture of
the system and the mode of operation of each segment are illustrated in
detail.  Linguistic models, knowledge representation, and parsing algorithms
are described and illustrated by means of selected examples.  Performance 
evaluations of the system in the application version on data base inquiry are 
reported and discussed.  Promising directions for future research are presented
in the conclusions.

    Approximate matching of strings is reviewed with the aim of 
surveying techniques suitable for finding an item in a database when
there may be a spelling mistake or other error in the keyword.  The
methods found are classified as either equivalence or similarity problems.
Equivalence problems are seen to be readily solved using canonical forms.
For similarity problems difference measures are surveyed, with a full
description of the well-established dynamic programming method relating
this to the approach using probabilities and likelihoods.  Searches for
approximate matches in large sets using a difference function are seen to
be an open problem still, though several promising ideas have been
suggested.  Approximate matching (error correction) during parsing is

Some Considerations Relating to the Cost-Effectiveness of Online Services

Lancaster, F.W.
.W
    In 1978 Collier presented some hypothetical data on economic aspects
of the use of online services as compared with subscriptions to printed
services in libraries.  Collier's view of the economics of online searching
seems misleadingly pessimistic because:

1.  It looks only at costs but not at effectiveness in comparing the two
    modes of access and searching.  An analysis combining cost and
    effectiveness aspects (i.e., a cost-effectiveness analysis) would
    give a completely different picture.

2.  The way the cost data are presented is grossly unfair to the online
    mode of access and use.

This work contains corrected information regarding online and printed

Co-Citation Context Analysis and the Structure of Paradigms 
.A
Small, H.
.W
    Many information scientists are concerned with the operation of 
document retrieval systems serving scientists in various fields.  The
scientists served by these systems are often members of what have been called
invisible colleges, groups of scientists in frequent communication with
one another and involved with highly specialized subject matters.  Often
such groups are considered to share an intellectual perspective regarding
this subject matter, which is sometimes referred to as a paradigm.

    The purpose of this paper is to show how it is possible to identify
paradigms, using the techniques of citation analysis.  I will operationalize
the notion of paradigm as a 'consensual structure of concepts in a field.'
Suppose we have obtained a set of papers pertaining to some topic.  Already
knowing something about the field, we read each text and mark passages in
which certain specific concepts are used or discussed.  For example, we
might find that a concept designated 'A' appears in some sub-set of the
papers.  Suppose further that we identify those papers in which concepts 'A'
and 'B' are used together in the same papers in a certain specified manner.
Clearly not all concepts will combine in a natural way, and not all authors
combining concepts 'A' and 'B' will do so in the same way, though some
predominant mode may emerge.  For a set of n concepts their structure is
given by the totality of admissible combinations of concepts taken from
two to n at a time.  The frequency with which a given combination occurs
in the sample of papers on the topic is a measure of the degree of consensus
regarding the particular concept combination within the corpus.  For
concepts taken two at a time, the structure can be displayed as a graph with
concepts as nodes and the relations between them represented as lines (arcs)
connecting the nodes.  This definition of concept structure is
similar to the semantic network of artificial intelligence except that in
our approach a measure of consensus weights each arc of the graph.

Cocited Author Retrieval Online:
An Experiment with the Social Indicators Literature
.A
White, H.D.
.W
    One mode of online retrieval in Scisearch or Social Scisearch involves
entering pairs of authors' names believed to be jointly cited by
subsequent writers and retrieving papers in which cocitations occur.  Six
pairs were formed with the names of four authors prominent in the social
indicators movement (Bauer, Duncan, Land, and Sheldon).  Documents by the
four were not specified.  It was thought that the pair Duncan and Land
would retrieve papers in which indicator-type data would be integrated with
path-analytic causal modeling.  All other pairs seemed likely to retrieve a
"general social indicators" literature.  The 298 retrieved papers confirmed
expectattions.  It was found that 121 papers generally cited social indicators
(SI) documents by the input authors and frequently had SI language in
their titles.  Other signs of content also identified them as papers of
the SI movement.  The 177 papers retrieved on Duncan and Land generally
cited causal modeling documents by the input pair and were path-analytic
in nature.  As expected, they were relatively "harder" than the first
group of papers, although the two groups are akin and are formally linked
through citations in certain papers.  An additional result is that papers
citing at least three of the input authors tend to be overviews of the SI
movement.

Experiments in Local Metrical Feedback in Full-Text Retrieval Systems
.A
Attar, R.
Fraenkel, A.S.
.W
    A method of iterative searching, using the results of one iteration search
to formulate the next iteration search, was applied to a full-text database
consisting of some 2400 documents and 1,3000,000 text-words of Hebrew and 
Aramaic.  The iterative method consists of clustering the documents returned
in an iteration, using weighting by proximity and by frequency simultaneously.
The process produces searchonyms, which are terms synonymous to keywords in the
context of a single query.  Augumenting or replacing keywords by searchonyms
via manual or automatic feedback leads to the formulation of the next iteration
search.  The results of the experiment are consistent with those of an earlier
small-scale experiment on an English database, and indicate that in contrast
to global clustering where the size of matrices limits applications to small
databases and improvements are doubtful, local metrical methods appear to be
well suited to arbitrarily large databases, improving precision and recall
simultaneously.  Further experiments using more test-queries run on even
larger databases should be made to collect further evidence as to the 
performance of these methods.

    A major deficiency of traditional Boolean systems is their inability to
represent the varying degrees to which a document may be written on a subject.
In this article we isolate a number of criteria that should be met by any
Boolean system generalized to have a weighting capability.  It is proven that
only one weighting rule satisfies these conditions--that associated with fuzzy-
set theory--and that this weighting scheme satisfies most of the other 
properties associated with Boolean algebra as well.  Probabilistic weighting
is then introduced as an alternative approach and the two systems compared.
In the limit of zero/one weights, all systems considered converge to 
traditional Boolean retrieval.

either type and/or with a Boolean structure for the queries.  They have also
suggested criteria which such systems ought to satisfy and record evaluation
mechanisms which partially satisfy these criteria.  We offer a more careful 
analysis, based on a generalization of the discrete weights.  We also look
at the weights from an entirely different approach involving thresholds, and
we generate an improved evaluation mechanism which seems to fulfill a larger
subset of the desired criteria than previous mechanisms.  This new mechanism
allows the user to attach a "threshold" to the query term.

These requests are translated by the interface into the appropriate commands
for whatever system is being interrogated.  System responses may also be
transformed by the interface into a common form before being given to the
users.  Thus, the network of different systems is made to look like a single
"virtual" system to the user.  The interface also provides instruction and
other search aids for the user.  The philosophy, design, and implementation

inexperienced end users.  A detailed analysis of the experimental usages 
showed that users were able to master interface operation sufficiently well
to find relevant document references.  Success was attributed, in part,
to a simple command language, adequate online instruction, and a simplified
natural-language, keyword/stem approach to searching.  It is concluded that
operational interfaces of the type studied can provide for increased usability
of existing system in a cost effective manner, especially for searchers.  
Furthermore, more advanced interfaces based on improved instruction and
automated search strategy techniques could further enhance retrieval
effectiveness for a wide class of users.

    The frequency characteristics of terms in the documents of a collection
have been used as indicators of term importance for content analysis and
indexing purposes.  In particular, very rare or very frequent terms are 
normally believed to be less effective than medium-frequency terms.  Recently 
automatic indexing theories have been devised that use not only the term
frequency characteristics but also the relevance properties of the terms.
The major term-weighting theories are first briefly reviewed.  The term
precision and term utility weights that are based on the occurrence
characteristics of the terms in the relevant, as opposed to the nonrelevant,
documents of a collection are then introduced.  Methods are suggested for
estimating the relevance properties of the terms based on their overall
occurrence characteristics in the collection.  Finally, experimental
evaluation results are shown comparing the weighting systems using the term
relevance properties with the more conventional frequency-based methodologies.

quality or effectiveness.  The present article assesses the validity of this

Colon Classification as a foundation for the automated analysis, representation

    Full text databases were created in two subject areas and queries solicited
from specialists in each area.  An automated full text indexing system, along
with four automated passage retrieval systems, was created to test the various
features of the Colon Classification.  Two Boolean-based systems and one simple
word occurrence system were created in order to compare the retrieval results
against types of systems which are in more common use.  The systems' retrieval
performances were measured using recall and precision and the mean expected

Author Cocitation:  A Literature Measure of Intellectual Structure
.A
White, H.D.
Griffith, B.C.
.W
    It is shown that the mapping of a particular area of science, in this
case information science, can be done using authors as units of analysis and
the cocitations of pairs of authors as the variable that indicates their
"distances" from each other.  The analysis assumes that the more two authors
are cited together, the closer the relationship between them.  The raw data
are cocitation counts drawn online from Social Scisearch (Social Sciences 
Citation Index) over the period 1972-1979.  GThe resulting map shows 
(1) identifiable author groups (akin to "schools") of information science,
(2) locations of these groups with respect to each other, (3) the degree of
centrality and peripherality of authors within groups, (4) proximities of
authors within group and across group boundaries ("border authors" who seem
to connect various areas of research), and (5) positions of authors with
respect to the map's axes, which were arbitrarily set spanning the most
divergent groups in order to aid interpretation.  Cocitation analysis of
authors offers a new technique that might contribute to the understanding of
intellectual structure in the sciences and possibly in other areas to the
extent that those areas rely on serial publications.  The technique
establishes authors, as well as documents, as an effective unit in 
analyzing subject specialties.

Progress in Documentation.  Word Processing:  
An Introduction and Appraisal
.A
Whitehead, J.
.W
    The "Office of the Future," "Office Technology," "Word Processing,"
"Electronic Mail," "Electronic Communications," "Convergence," "Information
Management."  These are all terms included in the current list of buzz words
used to describe current activities in the office technology area.  The high
level of investment in factories and plants and the ever-increasing fight to
improve productivity by automating the dull, routine jobs are usually quoted 
and compared with the extremely low investment in improving and automating
the equally tedious routine jobs in the office environment; the investment
in the factory is quoted as being ten times greater per employee than in the
office.  This, however, is changing rapidly and investment on a large scale
is already taking place in manhy areas as present-day inflation bites hard, 
forcing many companies and organizations to take a much closer look at their
office operations.

Document Clustering Using an Inverted File Approach
.A
Willett, P.
.W
    An automated document clustering procedure is described which does not
require the use of an inter-document similarity matrix and which is independent
of the order in which the documents are processed.  The procedure makes use of
an initial set of clusters which is derived from certain of the terms in the
indexing vocabulary used to characterise the documents in the file.  The 
retrieval effectiveness obtained using the clustered file is compared with that 
obtained from serial searching and from use of the single-linkage clustering
method.

A Fast Procedure for the Calculation of Similarity Coefficients in
in Automatic Classification
.A
Willett, P.
.W
    A fast algorithm is described for comparing the lists of terms representing
documents in automatic classification experiments.  The speed of the procedure
arises from the fact that all of the non-zero-valued coefficicents for a given
document are identified together, using an inverted file to the terms in the
document collection.  The complexity and running time of the algorithm are
compared with previously described procedures.
