    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
    Examines how the 71,1 million dollars in advertising revenue from 600 Web sites has been gained. 2/3 of this went to only 10 sites, the top 5 of which were Netscape, InfoSeek, Yahoo!, Lycos anc Excite. Offers 5 tips for effective banner advertising on Web pages. Multithreaded parallel search sites such as MetaCrawler and SavvySearch which enable a user to run several search engines simultaneously, pose a threat to advertising. Cyber 411, a new tool, queries 15 different search engines. Another category, software for querying multiple search engines such as WebCompass, willbuild a keyword searchable index with the summary of results which is output as an HTML file. Compares this with similar products including a Netscape product. InfoSeek and Excite offer mini-applications to place a labelled button on the browser's tool-bar to go straight to their respective search engine. VistaPass from AltaVista will run minimized on a task bar

    Abstract
    Users who want to exploit all the information sources on the Web will need an efficient search and selection tool e.g. a directory or search engine. Directories list Web sites and analyze their contents. Describes the behind-the-scenes work of documentalists specialized in surfing, tracking and indexing French language sites for the directory Nomade. Describes the creation of Nomade, its functioning and indexing, and how this new profession of 'cyber-documentalist' is changing the practices and functions of information professionals as they become Internet information organizers

    Abstract
    Purpose The purpose of this paper is to design a watcher-based crawler (WBC) that has the ability of crawling static and dynamic web sites, and can download only the updated and newly added web pages. Design/methodology/approach In the proposed WBC crawler, a watcher file, which can be uploaded to the web sites servers, prepares a report that contains the addresses of the updated and the newly added web pages. In addition, the WBC is split into five units, where each unit is responsible for performing a specific crawling process. Findings Several experiments have been conducted and it has been observed that the proposed WBC increases the number of uniquely visited static and dynamic web sites as compared with the existing crawling techniques. In addition, the proposed watcher file not only allows the crawlers to visit the updated and newly web pages, but also solves the crawlers overlapping and communication problems. Originality/value The proposed WBC performs all crawling processes in the sense that it detects all updated and newly added pages automatically without any human explicit intervention or downloading the entire web sites.

    Abstract
    Describes 4 search engines for the Internet: infoMarket Search; Yahoo and OpenText; Lycos Spider; and WebCompass. InfoMarket Search retrieves data from Web pages and information providers such as Disclosure, Information Access Company and Cambridge Scientific Abstracts. It is able to search millions of Web pages in under five seconds. Automated 'crawlers' index the complete text of Web documents. Yahoo enables users to search for specific words and phrases and conduct multilevel Boolean and weighted searches. Lycos spider offers support for HotJava and indexes 91% of the Web. WebCompass polls multiple search engines such as Lycos and InfoSeek for relevant Web pages. A personalized index of topics may be built and retrieved data stored in a format based on Microsoft Access 2.0

    Abstract
    The WebQuery system offers a powerful new method for searching the Web based on connectivity and content. Examines links among the nodes returned in a keyword-based query. Rankes the nodes, giving the highest rank to the most highly connected nodes. By doing so, finds hot spots on the Web that contain information germane to a user's query. WebQuery not only ranks and filters the results of a Web query; it also extends the result set beyond what the search engine retrieves, by finding interesting sites that are highly connected to those sites returned by the original query. Even with WebQuery filering and ranking query results, the result set can be enormous. Explores techniques for visualizing the returned information and discusses the criteria for using each of the technique

    Abstract
    The number of search engines on the WWW is continuing to grow. Despite their nearly-identical appearance each has its own qualities. AltaVista indexes over 30 million web pages and processes over 16 million search requests per day. It is one of the most heavily used search engines on the Web. The indexing is entirely automatic. This is achieved through free text; no controlled vocabulary is involved. discusses simple and advanced search modes; wildcards and truncation; Boolean searching and screening; case sensitivity; and the diffculties of indexing transitory postings. AltaVista does not index sites designated as closed to search robots

    Abstract
    Project SSG-FI at SUB Göttingen provides special subject gateways to international high quality Internet resources for scientific users. Internet sites are selected by subject specialists and described using an extension of qualified Dublin Core metadata. A basic evaluation is added. These descriptions are freely available and can be searched and browsed. These are now subject gateways for 3 subject ares: earth sciences (GeoGuide); mathematics (MathGuide); and Anglo-American culture (split into HistoryGuide and AnglistikGuide). Together they receive about 3.300 'hard' requests per day, thus reaching over 1 million requests per year. The project SSG-FI behind these guides is open to collaboration. Institutions and private persons wishing to contribute can notify the SSG-FI team or send full data sets. Regular contributors can request registration with the project to access the database via the Internet and create and edit records

    "Die Suchmaschine Google gilt oft als der beste Weg, um schnell etwas im Internet zu finden. Das war einmal, behauptet Apostolos Gerasoulis, jetzt gebe es www.teoma. com. "Wir sind die nächste Generation der Suchmaschinen", verspricht der Mathematikprofessor. Die Web-Sites von Google und Teoma sind ähnlich aufgemacht. Beide bieten eine weitgehend weiße Startseite mit wenigen, klaren Farben. Beide Suchmaschinen benutzen bei ihrer Arbeit zur Analyse der Anfragen einen komplizierten Algorithmus. Teoma hält den eigenen Ansatz aber für besser, weil dabei das Internet in Gruppen von Online-Gemeinschaften unterteilt wird. Dies liefere bessere Ergebnisse und erlaube eine nützlichere Auswahl. Zu einem Suchbegriff erscheinen bei Teoma zuerst links oben die bezahlten Verweise, darunter dann' alle anderen gefundenen Web-Seiten. Rechts erscheinen Vorschläge zur Verfeinerung der Suchanfrage, darunter manchmal Links von "Experten und Enthusiasten". Diese qualifizierten Antworten sind eine der Stärken, mit denen Teoma wuchern möchte. Sie sind besonders für Anfänger nützlich, die nach allgemeinen Themen wie Afrika" oder "Fußball" suchen. Allerdings könnte dieser Ergebnisdienst Nutzer auch überfordern, gerade wenn sie an das einfache Google gewöhnt seien, kritsiert Rob Lancaster von der Yankee Group."
