In order to facilitate information retrieval, and at the same time guarantee the pertinence of the yield, XML must be coupled with a meaningful taxonomy, based on the hierarchical arrangement of subject groupings. Within the subject groupings the researcher must be able to broaden or narrow the search, as well as find related lateral topics. The arrangement of subject hierarchies must be logical, consistent, and expansible. As most documents can be classified within more than one category, the topological arrangement should be internally consistent. Each broad category must be similarly subdivided using a standard schema.
Searchers can anticipate the arrangement, navigate easily, and thereby retrieve relevant data.
Additionally, a subject relevancy percentage or weighted system is highly effective. In summary, this white paper is an excellent recap of library science fundamentals, presented in the language of the new technology for today's information professional. Lurking as a player in this scenario is the usual suspect, Microsoft Outlook. The researchers say the worm uses Outlook to send itself hidden in a PDF file. When the recipient opens the file using Acrobat Reader, a game is launched that encourages the recipient to click on a picture of a peach.
