Mayor Physical Description xii, 84 leaves General Note Computer print out   Undergraduate thesis(B.L.I.S.)--University of the Philippines, Diliman   Vita Summary, Etc. A total of 4809 hits were evaluated. The result of the test shows that when seeking information on the social sciences, Infoseek garnered the top rank, followed by Excite, AltaVista, Hotbot, WebCrawler and Lycos. The low score that each search engine got can be attributed to two factors, spamming and the ambiguiities caused by the complexity of language used in indexing and in searching   The growing popularity of Internet as a source of information has fueled the growth of search engines. Search engines are facilities that help users find information through the vast reservoir of knowledge that can be found on the Internet. This study is an evaluation of the performance of the six popular search engines   The six search engines, Infoseek, Hotbot, AltaVista, Excite, WebCrawler and Lycos were evaluated using terms taken from the 4th edition of Macrothesaurus for Information Processing in the Field of Economics and Social Development. A total of sixty eight terms were randomly taken and were formulated as queries that were then used on the six search engines. Fourteen of the sixty-eight were resubmitted using the search syntax of each search engine. The first ten hits generated were evaluated for their accuracy, reliability and currency. Also evaluated were the ease of use and other features and services provided by the search engines, as well as their support for advance searching   This paper also tackles the factors that affect the indexing and ranking of sites. the factors that affect the quality of the index of a search engine are size, the number of pages that the spiders can crawl in a day, freshness of the index, the number of days before a submitted or a non-submitted page get indexed, depth, frames support, password protected sites, link popularity, learns frequency, robot.txt and meta robots. The factors that affect how search engine rank sites are the extra boost given to reviewed sites, link popularity, meta tags, the presence of invisible texts and tiny texts, indexing of the comment and ALT attribute of an image, the use of stop words, stemming and case sensitivity Subject Added Entry - Topical Term Online bibliographic searching   Web search engines   World Wide Web (Information retrieval system) Location UP DLS LG993.5 1999 L4 M39 Regular Circulation LS-UNACC. 961T Textual Physical Form Designator Thesis           Physical Location University of the Philippines Diliman: School of Library and Information Studies LG993.5 1999 L4 M39           Digital Copy Not Available          Add to Book Cart  |   Download MARC
