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

Abstract

Presents a view of portal sites as a radically different model from those currently embraced by traditional information companies. The concept of a portal as a starting point that Web users pass through is an uncomfortable one for most traditional services, which are designed to be one-stop destinations for information. It will become increasingly difficult for even the largest data warehouses to compete with the rising volume of Web content if closed end information models are not abandoned in favour of distributed ones which better reflect the reality of what is available to information consumers. Dow Jones Interactive Publishing is among the first to embrace a distributed model by indexing the sites which it believes have customer value, regardless of whether they offer their content on the subscriber service
