Evaluates the retrieval performance of an algorithm that automatically categorizes medical documents, which consists in assigning an International Code of Disease (ICD) based on well-known information retrieval techniques. Reports on experimental results that tested precision using a database of over 20,000 medical documents. (Author/LRW)

A correlation between recall (the retrieval of all available relevant documents) and quantity of text which served as a source of index terms on input can reasonably be expected. Specifically, recall should decrease as the quantity of text serving as a source of index terms is restricted. On the other hand, the time for indexing and therefore the…

The mathematical model proposed describes a computerized bibliographic information system which includes a method--document learning--of improving the set of index terms assigned to a document representative. Inputs to the information system (index terms and query), relevance feedback, and assumptions concerning the model are discussed.…

The application of computer technology to storage and retrieval of geoscience data has increased markedly since about 1966, and has resulted in the publication of numerous papers describing various aspects of this work. Unfortunately, these are widely dispersed in the literature, many in relatively obscure journals, proceedings and other sources.…

Describes an alternative method for indexing images in an image database. The method consists of manually indexing a selected reference image, and then using retrieval by graphical content to automatically transfer the manually assigned index terms from the reference image to the images to be indexed.

With the growth of computer technology, bibliographic data bases have developed into sophisticated online research tools. The major data bases are produced by abstracting and indexing (A&I) publishers. Vendors purchase the A&I publishers' machine readable tapes, then sell computer access to the tapes to information based organizations such…

Because of the need for adequate reference tools in the new area of data banks for the field of terminology (there are currently 25 term banks in existence and more are planned), this bibliography lists some 350 references selected from a large number of both primary and secondary sources. It includes some entries selected from a list of…

As the scholarly record has grown, so have bibliographic control instruments, some of which are in machine readable form. The expense of setting up an organization for access to the machine readable data bases seems beyond the budgets of most institutions. The objective is to establish a dependable service organization to make machine readable…

Sixth in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine-readable form, this report deals with the query language, search strategy and related considerations for a particular information storage and retrieval system. One section of the…

Reports on a series of programs that have been developed to process data bases, consisting of textual items, and to index and arrange (classify) the data items in accordance with an automatically generated classification system. (Author)

The publication of papers describing activity in computer-based storage and retrieval and geoscience information has continued at a vigorous pace since release of the last bibliography, which covered the period 1946-69 (ED 076 203). A total of 211 references are identified, nearly all of which were published during the three-year period 1970-72…

Information services provided by the reference librarians at the University of California at Los Angeles (UCLA) are outlined as an introduction to this document on projected services to the public by the Center for Information Services (CIS). The report discusses the types of data base which may be searched (bibliographic reference tapes, full…

Reviews computer applications in judicial, legal, and legislative information activities being used to support litigation and court administration, assist in searching for legislation and laws, aid criminal justice information systems, and provide appropriate bibliographic and reference assistance. Management issues in automating systems are…
