Abstract

An important stage in the process or retrieval of objects from a hypertext database is the creation of a set of internodal links that are intended to represent the relationships existing between objects; this operation is often undertaken manually, just as index terms are often manually assigned to documents in a conventional retrieval system. In an earlier article (1994), the results were published of a study in which several different sets of links were inserted, each by a different person, between the paragraphs of each of a number of full-text documents. These results showed little similarity between the link-sets, a finding that was comparable with those of studies of inter-indexer consistency, which suggest that there is generally only a low level of agreement between the sets of index terms assigned to a document by different indexers. In this article, a description is provided of an investigation into the nature of the relationship existing between (i) the levels of inter-linker consistency obtaining among the group of hypertext databases used in our earlier experiments, and (ii) the levels of effectiveness of a number of searches carried out in those databases. An account is given of the implementation of the searches and of the methods used in the calculation of numerical values expressing their effectiveness. Analysis of the results of a comparison between recorded levels of consistency and those of effectiveness does not allow us to draw conclusions about the consistency - effectiveness relationship that are equivalent to those drawn in comparable studies of inter-indexer consistency

Abstract: Provides tips for searchers of full text online databases and examines the coverage policies of full text database producers which may change without notification to users. Most full text newspaper files do not carry even bibliographic listings for syndicated columns not created by their own staff. Looks at the development of full-text CD-ROM databases and claims that full-text, though expensive, is the wave of the future

Abstract: State of the art review of the development of full text databases, encompassing: types of commercially available full text databases; online systems for full text databases; CD-ROM databases for full text databases; full text databases on magnetic discs or tapes; creation of full text databases; searching and display requirements for full text searching and software. Concludes that bibliographic information services without full text support solve only half of the retrieval problems

Abstract

In Jan 1997 AOL annouced its acquisition of Personal Library Software, a leading developer of information indexing and search technologies, which are at the core of online a CD-ROM products from major providers such as Dow Jones and Knight Ridder. AOL is the world's leading Internet online service. Quotes the company heads concerning the advantages of the deal for searchers but reports that no specific details of its terms have been released. Outlines the history of the companies focusing on the role of Matthew Koll founder of Personal Library Software and now joining AOL and the reactions of information professionals
