The Importance of the Difference in Text Types to Keyword Extraction: Evaluating a Mechanism

Information exists in every aspect of our life. The expansion of the web has helped to this direction. The web feeds us with enormous information and the widespread use of computers and other hardware appliances has lead us to a state where we have a lot of information in our hands, but many times it is useless. People are not able to find information that they really need but already own. How many times have you tried to find a specific article that you have, or a specific mail that you received, or even an SMS from someone saying something specific. For this reason many information retrieval techniques have been proposed and many information extraction mechanisms have been created. In this paper we will provide the experimental evaluation of a keyword extraction mechanism and how we treat different types of text (news articles, publications, e-mails). This keyword extraction mechanism is a part of a complete system that includes information retrieval, information extraction, categorization and publication of information to a personalized portal.
