| Abstract(in English) | Appropriate choice of query word are crucial to obtain a good search result. If it is too vague or too general, several thousand of results would be obtained. On the other hand, if it is too specific, the number of documents retrieved would be too few. More fine keywords are necessary in the former and query expansion is necessary in the latter. Speciality and granuality are two key aspects to evaluate appropriateness of of keywords in searching documents. This report proposes a method to analyse speciality and granularity of keywords using global and local document frequencies of the keywords. |
