6. THE COMMITTEE ON TOXICOLOGY AND THE ADVISORY CENTER ON TOXICOLOGY OF THE
NATIONAL RESEARCH COUNCIL. Ralph C. Wands, National Academy of Sciences, 2101 Constitution
Avenue, Washington, D. C. 20418
The origin and development of the Committee on Toxicology and the Advisory
Center on Toxicology is reviewed briefly. The discussion is centered on how the
Committee and the Center assist their sponsoring Federal Agencies. The interactions
and mutual responsibilities of these three units is described. Information is also
given on the literature holdings and indexing of the Center.
7. TOWARD A NATIONAL SYSTEMS RESOURCE IN TOXICOLOGY. Charles N. Rice,
National Library of Medicine, 8600 Rockville Pike, Bethesda, Maryland 20014
A 1966 report of the President's Science Advisory Committee (Handling
of Toxicological Information, U. S. Government Printing Office, June 1966)
recommended steps to accomplish more effective marshalling and use of
information in toxicology. As a result of Executive Order of the President
a program for establishing a computer-based system for national coordination
and support of toxicological information, whether published or available in
unpublished form, has been established at the National Library of Medicine.
Planning for a national system is in progress. The relationship of this
system to other national resources for information processing and dissemination,
and progress in planning, will be discussed.
TUESDAY MORNING - SYMPOSIUM ON TRAINING IN THE USE OF CHEMICAL LITERATURE - Joint
with Division of Chemical Education - Abstracts in Section CHED.
TUESDAY AFTERNOON - SYMPOSIUM ON WHOLE TERM SEARCHING - K. H. Zabriskie, Presiding
8. TERM FREQUENCY DATA--A GUIDE TO TEXT SEARCHING STRATEGY. Kenneth H.
Zabriskie, Jr., BioSciences Information Service of Biological Abstracts, 2100 Arch
Street, Philadelphia, Pa., 19103.
In computer files which are to be searched by text matching there are three
broad classes of terms: frequent, average, and rare. Each of these classes
requires a different technique for economic and efficient searching. Representative
data from current scientific information collections is presented with
examples of the search strategies employed in each case. Vocabulary management
is discussed as a tool for file organization and for development of most appropriate
search strategies. Particular attention will be paid to the troublesome
case where the searcher desires the co-occurrence of two or more frequently
9. USE OF WORD FRAGMENTS IN COMPUTER-BASED RETRIEVAL SYSTEMS. D. S. Colombo and J.
E. Rush, Department of Computer and Information Science, The Ohio State University,
Columbus, Ohio 43210
A numberof computer-based text-search systems currently in operation permit the
use of word fragments as search terms. The full potential of this feature is not
realized because of the uncertainties associated with the use of word fragments. A
pair of dictionaries is described which makes possible the selection of appropriate
fragments both for "generic" retrieval and for retrieval of specific words. The
general nature of the computer program used to produce the dictionaries, in terms of
size distribution and population density, are described.
10. UNITED KINGDOM EXPERIENCES IN THE OPERATION OF A RETRIEVAL AND DISSEMINATION
SERVICE BASED ON CAS SEARCH TAPES. A. K. Kent, Chemical Society Research Unit,
University of Nottingham, Nottingham, England
The Chemical Society Research Unit, established in Nottingham in August 1966, is
presently providing a current-awareness SDI Service to more than 700 users in Universities,
Government and private institutions in the U.K., based on the CAS Chemical Titles
and Chemical Biolotical Activities tapes. We shall report on two main aspects of the
4ork that has been done in the past two years. First we shall describe the evaluation
studies we have made on CT and CBAC, with special reference to precision, recall and
ease of use. Second we shall describe some of the problems which face a naive user of
computer-based services of this type and attempt to highlight the most significant
areas of difficulty and the solutions which we have attempted, or will attempt in the
future. In particular we shall argue for the need for a considerable increase in
effort in developing useful and usable tools to guide and aid the user in the construction
of profiles for free-text searching.
11. SERVING THE CHEMIST THROUGH THE IBM TECHNICAL INFORMATION RETRIEVAL CENTER.
Judith D. Farrell, IBM Corporation, Dept. 10/777, Old Orchard Rd., Armonk, N.Y. 10504
The chemist in today's industrial environment is a member of a multidisciplined
community. He is called on to serve not only in his dedicated field of interest but
also as an advisor to engineering, management, manufacturing, and developmental staffs.
The technical information transfer which forms the decision medium for the chemist has
grown beyond the individual capabilities of correlation and digestion. To serve the
chemist and the total IBM community, an automated procedure for retrieval of information
from a completely interdisciplinary data base was established, based on the techniques
of normal text searching. ITIRC - the IBM Technical Information Retrieval Center - is
dedicated to provide another link between the scientist and the ever-expanding world of
,12. FULL TEXT SEARCH OF SEVERAL DATA BASES. Margaret T. Fischer, Luther Haibt, Time
Inc., Time & Life Building, Rockefeller Center, New York, N.Y. 10020
Thirty-seven million computer-readable words of natural text from three sources --
magazine stories, abstracts of magazine articles and dispatches from news correspondents
-- were prepared for machine search by staff at IoB.Mo's Thomas J. Watson Research Center
and Time Inc.'s Information Handling Project. The team collected and analyzed
16,000 questions and answers which were put to these files and selected nearly 4,000
for a computer search. Five criteria influenced the success of computer search: 1)
The wording of the query, 2) the user's familiarity with the file as well as the system,
3) the querier's ability to spell, 4) the words and style in which the text was written
and 5) whether the answer required document or information (fact) retrieval.
WEDNESDAY MORNING & AFTERNOON- SYMPOSIUM ON REDESIGN OF THE TECHNICAL LITERATURE -
C. L. Bernier, Presiding.
CONDENSED TECHNICAL LITERATURES. Charles L. Bernier. The
Squibb Institute for Medical Research. Georges Road, New
Brunswick, New Jersey 08903.
Biologists, chemists, medical men and others have too many words to
read. Too many words are in languages other than English and they annear
in too many journals, reports, and books. Gabriel Marcel has written, "But
the problem in fact is how to pass through multiplicity so as to transcend
it and not at all how to escape it." We need a solution to this old problem.
Condensation by evaluation, a possible solution, must be done bv
authorities, such as author, editor, and his reviewers. Their conclusions
about a manuscript can be expressed in a sentence like an aphorism of
Hippocrates stating conclusions, results, intentions, etc. The statements
would combine the backgrounds of authorities with information from manuscripts.
Condensed literatures of organized collections of terse statements
would not be substitutes for other literatures, but would provide
evaluated guides to them. Statements, organized, e.g., by the U.D.C.,
could be published as newspapers or reference works. Manuscripts stimulating
the statements could be referenced. Backlogs of reading would be
avoided because the past would be embodied in the statements by authorities
writing them. It is hoped that condensed literatures would help
professional people to keep up in fields one or two orders of magnitude
broader than they now can read.
14. THE DUALITY OF QUICK AND ARCHIVAL COMMUNICATION. Arley T. Bever, Associate
Director for Research Analysis and Evaluation, Division of Research Grants, National
Institutes of Health, Bethesda, Md., 20014. The future of journals as media
through which new contributions enter the recorded body of science is secure. They
will proliferate as science differentiates and as the volume of publication in
