متن کاملTerm Weighting: Novel Fuzzy Logic based Method Vs. Classical TF-IDF Method for Web Information Extraction
Solving Term Weighting problem is one of the most important tasks for Information Retrieval and Information Extraction. Tipically, the TF-IDF method have been widely used for determining the weight of a term. In this paper, we propose a novel alternative fuzzy logic based method. The main advantage for the proposed method is the obtention of better results, especially in terms of extracting not...
