The first of a series of five papers whose aim is to find a rational basis for indexing and some means to evaluate it. (Author)

The Upper Midwest Regional Educational Laboratory has developed a complete information system as a support for its educational development program. (Author)

Describes the background, document and subject coverage, access points, indexing, and other features of the online version of Energy Bibliography and Index (EBIB). A set of nine figures illustrate such things as a sample EBIB record, searchable fields in the EBIB database, and searching EBIB by index terms. (JL)

Studied the relationship between the vocabulary of user queries and the vocabulary of documents relevant to the queries, as well as the value of adding to the document description record in a retrieval system keywords from previous queries for which the document had proved useful. Eight references are listed. (FM)

This proposed alternative for resequencing output from online searches of journal literatures includes sorting hits by the journal in which they appear, and organizing hits within journal by the number of hits each journal contains. Benefits to the user are discussed, and a "Bradfordized" example is appended. (Author/SW)

SEQUEL, a programing language designed for use in database management systems, is shown to be useful in document retrieval systems. Its retrieval capabilities are detailed, some disadvantages noted, and possible additional features are suggested. (FM)

Provides a directory of online databases available as of October 1979. Scope, vendor, update frequency, and user charges are included. (RAA)

Offers suggestions for retrieval of bibliographic data by those interested in revealing interdisciplinarity and by those interested in creating interdisciplinarity, or interdisciplinary syntheses. Demonstrates Dialog's RANK command as a means of revealing interdisciplinarity in any field, and describes examples of synthesizing work from one…

Discusses the need for tools that analyze Earth changes in time ranges, and describes a data structure for creating and managing archives of thematic maps derived by classifying remotely sensed images by soft techniques (soft maps). Considers time-based models and provides an example of the new data structure. (Author/LRW)

Describes the CCF (Common Communication Format) and the INFLIBNET (Information and Library Network) standard, two forms of metadata developed to represent the bibliographic resources available to libraries and to facilitate easy retrieval of resources. Proposes a crosswalk between core CCF and INFLIBNET bibliographic data fields and 15 Dublin Core…

Discusses hierarchical text classification for electronic information retrieval and the measures used to evaluate performance. Proposes new performance measures that consist of category similarity measures and distance-based measures that consider the contributions of misclassified documents, and explains a blocking measure that identifies…

Describes a test collection that was developed as a multi-purpose testbed for experiments on the Web in distributed information retrieval, hyperlink algorithms, and conventional ad hoc retrieval. Discusses inter-server connectivity, integrity of server holdings, inclusion of documents related to a wide spread of likely queries, and distribution of…

Discusses the use of text retrieval methods based on probabilistic models with Chinese language material, which are modeled on the Okapi information retrieval system. Topics include system architecture, test collections, weighting functions, and algorithms. (Author/LRW)

Presents a background on theory in knowledge organization, which has moved from an epistemic stance of pragmatism and rationalism (based on observation of the construction of retrieval tools), to empiricism (based on the results of empirical research). Discusses historicism, external validity, classification, user-interface design, and…
