| Abstract(in English) | To support the user's re-structuring of a large amount of social information such as newspaper articles, we build a social information visualizaion system with the functions of 1) displaying the information using the terms, their spatial relations on time axis and the original text and 2) re-clustering the information based on the user's feedback. To realize effective re-clustering, the experiments concerning the term weighting and selection methods were conducted. The experimental results suggested that for the documents containing a small percentage of the co-occurring terms, the forced co-occurrence method is effective for improving the precision and recall. For the documents full of co-occurring terms, the TFIDF or x^2 based method should be used for better recall and the forced co-occurrence for better precision. |
