    Abstract
    Describes the shortcomings of search engines for the WWW comparing their current capabilities to those of the first generation CD-ROM products. Some allow phrase searching and most are improving their Boolean searching. Few allow truncation, wild cards or nested logic. They are stateless, losing previous search criteria. Unlike the indexing and classification systems for today's CD-ROMs, those for Web pages are random, unstructured and of variable quality. Considers that at best Web search engines can only offer free text searching. Discusses whether automatic data classification systems such as Infoseek Ultra can overcome the haphazard nature of the Web with neural network technology, and whether Boolean search techniques may be redundant when replaced by technology such as the Euroferret search engine. However, artificial intelligence is rarely successful on huge, varied databases. Relevance ranking and automatic query expansion still use the same simple inverted indexes. Most Web search engines do nothing more than word counting. Further complications arise with foreign languages

    Discusses the evolution of online databases during the 1990s considering the effect of cheap information accessed through the Internet. InfoSeek includes Associated Press Online, Reuters Business Report, Commerce Business Daily and Cambridge Scientific Abstracts for a basic 9.95 dollars per month. PR Newswire offers an automated faxback system of press releases at no charge to the caller. CD-ROM directories are making online access almost obsolete. With greater numbers of sophisticated electronic competitors, survival can only be achieved through high quality access, accuracy and added value

    Abstract
    The effectiveness of an information system is related to its readability, browsability, searchability and interactive assistance. Interactive assistance provides customized help for particular users in particular situations. It can be proactive or restrictive. Systems have been developed for reference work and CD-ROM based bibliographic indexes. Prototype systems for the Internet include: Ask Alcuin, meta-search engines, and WebArcher

    Abstract
    The World Wide Web is rapidly filling with more text than anyone could have imagined even a short time ago, but the task of isolating relevant parts of this vast information has become just that much more daunting. Richard Belew brings a cognitive perspective to the study of information retrieval as a discipline within computer science. He introduces the idea of Finding Out About (FDA) as the process of actively seeking out information relevant to a topic of interest and describes its many facets - ranging from creating a good characterization of what the user seeks, to what documents actually mean, to methods of inferring semantic clues about each document, to the problem of evaluating whether our search engines are performing as we have intended. Finding Out About explains how to build the tools that are useful for searching collections of text and other media. In the process it takes a close look at the properties of textual documents that do not become clear until very large collections of them are brought together and shows that the construction of effective search engines requires knowledge of the statistical and mathematical properties of linguistic phenomena, as well as an appreciation for the cognitive foundation we bring to the task as language users. The unique approach of this book is its even handling of the phenomena of both numbers and words, making it accessible to a wide audience. The textbook is usable in both undergraduate and graduate classes on information retrieval, library science, and computational linguistics. The text is accompanied by a CD-ROM that contains a hypertext version of the book, including additional topics and notes not present in the printed edition. In addition, the CD contains the full text of C.J. "Keith" van Rijsbergen's famous textbook, Information Retrieval (now out of print). Many active links from Belew's to van Rijsbergen's hypertexts help to unite the material. Several test corpora and indexing tools are provided, to support the design of your own search engine. Additional exercises using these corpora and code are available to instructors. Also supporting this book is a Web site that will include recent additions to the book, as well as links to sites of new topics and methods.

    Abstract
    Presents a state of the art review of WWW search engines from the earliest Internet precursors and noting: prblems inherent in the current range of WWW search engines; problems of searching the WWW (link persistence and lack of integrated search software); and analyzing the resulting search engine types (keyword or directory). Compares search engines of all types across their generic features (database content, retrieval software, and search interface), rather than on a search engine by search engine basis. Considers wider information access issues arising from the nature of the Internet and Web search engines and proposes a general strategy for using web search engines. Comments on the irony that a unitary global information space accessible via 1 freely accessible software package (WWW client browser) should be so balkanized by a plethora of search engines in complete reverse of the traditional world of printed, CD-ROM and online databases, where a limited number and comparatively stable range of search tools attemps to homogenize a large number of physically separate and disparate collections
