Thesis Title: the Linguistic dimension in InformationSciences: An applied study to use indexing languagesin the work of search engines.Candidates Name: Sabri Elhaj Elmubarak ElaminDegree: PhD in information & Library SciencesGraduates college – University of KhartoumSupervised By: Ustaz. Abu baker Elsiddig OsmanYear: 2007Along with increasing use of international databases, crossculturalindexing is becoming more common and tools likemultilingual thesaurus are urgently needed. This studyconcentrates on cultural and linguistic problems inmultilingual thesaurus. Very little attention has been paid tothis topic in Arabic research and the need for this kind ofstudy has grown rapidly. This study has proved that all theengines tested had ranking schemes that were not welldocumented, being based on how many times search wordswere mentioned, whether or not they appeared early in thedocument, whether or not they appeared close together, andhow many search terms were matched. I did not find theIVranking schemes very useful, as relevant and irrelevantpages frequently had the same scores. It is found thataggregating meaning is possible on the Internet becausethere are many easily accessible semantic objects to beharvested. Analysis of the aggregations can suggest patternsof high likelihood that permit applications to recommend,adapt, profile, forecast and so on. It has been proved that theterminology and thesaurus construction standards andguidebooks provide very little details and considerationabout equivalence. It has been indicated that Google mayindex billions of Web pages, but it will never exhaust thestore of meaning of the Web. The reason is that Google'saggregation strategy is only one of many different strategiesthat could be applied to the semantic objects in public Webspace. It has been found that web search engines do notconspire to suppress controversy, but their strategies do leadto organizationally dominated search results deprivingsearchers of a richer experience and, sometimes, of essentialdecision–making information. These experiments suggestthat bias exists, in one form or another, on the Web andshould, in turn, force thinking about content on the Web in amore controversial light
