- Abstract
- Looks at some of the ways Web pages are designed to improve their ranking by Internet search engines. This is known as search engine persuation (SEP) and it has added a new obstacle to eliminating junk and obtaining successful search results. SEP methods include: taking advantage of ranking principles, abuse of the meta tag which describes the page, misusing the meta tag on the Netscape browser which indicates numbers of other pages linked to that page, and the growth of companies offering to improve ranking

- Abstract
- Reports results of a study, conducted at Hawaii University, Department of Information and Computer Science, to understand the novide searchers' experience in learning to use a WWW search engine. Without prior searching instruction, undergraduate novives wrote structured self reports during their first session on a Web search engine. Users choose their own topics and followed written instructions that prompted them to describe thoughts and feelings during specified stages of the search; pre search formulation; search statement formulation; search strategy; and evaluation of the results. The sentences in the self reports were numbered and then coded according to their affective or cognitive function. The affective sentences reveal how users set goals and limit the scope of the cognitive operations. Search acts appear to be governed by an affective filter that organizes incoming information and provides criteria for ranking cognitive relevance to search goal. Content analysis identifies reasons users have for rating self confidence, stress level, satisfaction, usefulness, and success with future searches

- Abstract
- Investigates the problems of using commercial search engines for Web link research and attempts to clarify the nature of the problems involved in the use of these engines. The limitations which are inherent in commercial search engines should cause researchers to have reservations about any conclusions that rely on these tools as primary data gathering instruments. The shortcomings are market driven rather than inherent properties of the Web or of Web searching technologies. Improved functionalities are within the technical capabilities of search engine programmers and could be made available to the research community

- Abstract
- One difference between a portal and a mere search engine is that portals are now the recipients of investments from major media interests, a trend which may have important ramifications for the Web publishing. Points to AOL as a successful portal, quotes a compilation of 10 favourite Web activities and examines the contents of a portal, typically a search engine or directory plus free e-mail but also news services. A significant trend is for portals to replicate themselves in different languages. Presents a list of the big portal players

- 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
- This reviews looks briefly at the history of WWW search engine development, considers the current state of affairs, and reflects on the future. Networked discovery tools have evolved along with Internet resource availability. WWW search engines display some complexity in their variety, content, resource acquisition strategies, and in the array of tools the deploy to assist users. A small but growing body of evaluation literature, much of it not systematic in nature, indicates that performance effectiveness is difficult to assess in this setting. Significant improvements in general-content search engine retrieval and ranking performance may not be possible, and are probalby not worth the effort, although search engine providers have introduced some rudimentary attempts at personalization, summarization, and query expansion. The shift to distributed search across multitype database systems could extend general networked discovery and retrieval to include smaller resource collections with rich metadata and navigation tools

- Abstract
- The Northern Light Internet search engine was inaugurated in Aug 1997. The service differs from existing services in that it classifies search results in a set of custom search folders and for a modest fee provides access to a range of bibliographical resources not normally available via the Web. Paymant may be made online via a simple transaction. The custom search folders enable users to refine searches more easily than with other search engines. However, the search commands to not permit truncated or wild card searches

- Abstract
- To use the electronic resources of the Internet effectively, reference librarians must learn to use the various search engines to their best advantage. Describes the following Web sites which provide help for librarians in improving their Internet searching skills: the Bergen County Cooperative Library System which has links to some well-known directories and search engines; the Spider's Apprentice, which provides ratings and in-depth analysis of search engines, a FAQ document useful to the beginning searcher, and an online discussion forum; ZDNet's WebSearchUser which has feature articles, reviews and tutorials; and Search Engine Watch which reports new developments in search engines. URLs for these and other resources are given

- Abstract
- Search engine coverage relative to the estimated size of the publicly indexable web has decreased substantially since December 97, with no engine indexing more than about 16% of the estimated size of the publicly indexable web. (Note that many queries can be satisfied with a relatively small database). Search engines are typically more likely to index sites that have more links to them (more 'popular' sites). They are also typically more likely to index US sites than non-US sites (AltaVista is an exception), and more likely to index commercial sites than educational sites. Indexing of new or modified pages byjust one of the major search engines can take months. 83% of sites contain commercial content and 6% contain scientific or educational content. Only 1.5% of sites contain pornographic content. The publicly indexable web contains an estimated 800 million pages as of February 1999, encompassing about 15 terabytes of information or about 6 terabytes of text after removing HTML tags, comments, and extra whitespace. The simple HTML "keywords" and "description" metatags are only used on the homepages of 34% of sites. Only 0.3% of sites use the Dublin Core metadata standard.

- Abstract
- Internet Newsgroup archives on services such as DejaNews offer important sources of information that may not be found elsewhere online. Describes the content of the DejaNews Database which goes back to 1995 and covers more than 14,000 newsgroups. There are 2 search options: quick search and power search. Most Web search engines offer links to DejaNews, but AltaVista offers a smaller alternative and supplement to DejaNews. Reference.COM also offers a searchable archive, as well as a useful current awareness service which allows setting up multiple searches under the user profile tab
