Describes the PADOK-II project in Germany, which was designed to give information on the effects of linguistic algorithms on retrieval in a full-text database, the German Patent Information System (GPI). Relevance assessments are discussed, statistical evaluations are described, and searches are compared for the full-text section versus the…

Survey to determine impact of online availability on subscriptions to printed publications found 2-5 percent annual attrition in subscriptions to printed publications over past five years is not related solely or primarily to availability of online databases, and evolution of online databases and printed publications as separate entities is…

Recommends those cases in which a database search of CIJE would benefit from a supplementary manual search of Education Index. Article also presents findings of a study of the usefulness of CIJE abstracts (1969-1978) which suggest that the user choose different online printing formats for different years. (JD)

This research project was motivated by results of earlier work (Katzer et al., 1982) on the overlap among document representations. In the earlier study, one representation used in the INSPEC database proved to perform unexpectedly well in comparison with other commonly used representations, such as controlled vocabulary or free-text terms from…

To assess value of abstracts in online information retrieval, this study attempts to match free-text search phrases to index terms and provides classification of documents indicating form of retrieval to be expected by searching three databases--Energyline; Management Contents; and America, History and Life. Results of a sample search are…

Studies an information retrieval system for bibliographic entries or abstracts using queries from the INSPEC database on the FOLIO system at Stanford University (California). Highlights include strategies for distributing indexes across a set of processors and for performing queries in parallel; inverted lists; simulations; local area networks;…

Describes a study that supported two hypotheses concerning the use of anaphors in information retrieval: first, that anaphors tend to refer to integral concepts rather than peripheral concepts; second, that various term weighting schemes are affected differently by anaphoric resolution. The implications for the use of anaphoric resolution for…

Reports on a study that analyzed 3,746 papers obtained from retrospective searches of the Medline database according to language, length of abstract, depth of indexing, and inclusion of author's address. The focus is on scientific production in Slavonic countries and the information value of Slavonic papers in Medline. (10 references) (MES)

OASIS (Oceanic and Atmospheric Scientific Information System) is an information retrieval service that furnishes ready reference to the technical literature and research efforts concerning the environmental sciences and marine and coastal resources. It provides computerized searches of both NOAA (National Oceanic and Atmospheric Administration)…

A study of 1264 incidents of journal mutilation at New York University indicates no relationship between the availability of indexing and abstracting services on CD-ROM databases and mutilation. Recommends posting warnings; raising awareness; providing adequate photocopiers, change, and vendor card machines; announcing closing time; encouraging…

With "Chemical Abstracts" and "Science Citation Index" both now available for citation searching, this study compares the duplication and uniqueness of citing references for works of chemistry researchers for the years 1999-2001. The two indexes cover very similar source material. This analysis of SciFinder Scholar and Web of…

Structured abstracts containing several subheadings (background, aim, method, results, and conclusions) have replaced traditional abstracts in most medical journals. The results of 2 studies, the first of 52 readers using an electronic database and the second of 56 readers using a printed database, suggest that it is easier for readers to search…

This study describes the use and value of the major information products and services provided by the Defense Technical Information Center (DTIC). These products and services include technical report distribution on an on-demand basis and through the Automatic Document Distribution (ADD) program; secondary information dissemination through online…

Describes a survey of academic libraries that examined whether the availability of abstracting and indexing services online has resulted in the cancellation of equivalent print subscriptions. The results indicate that subscriptions are being cancelled at a significant rate because of cost and lack of use rather than the availability of online…

Describes a survey of science and engineering faculty at the University of Illinois at Chicago that investigated their use of paper and electronic services that offer bibliographic access to research literature. The impact of the availability of locally mounted databases is discussed, and directions for future research are suggested. (eight…
