| Abstract(in English) | In order to merge various onomastic expressions for valuable tweet topic retrieval/clustering, a construe- tion method of twitter dictionaries based on lexical extraction and their time-correlation is proposed. In this paper, we propose Maximal substrings to extract efficient lexical set and adaptation to remove superfluous substrings. Moreover, similarities between keywords are calculated by the time-correlation of each word and co-occurrence probability. Through experiments with 101,714/354,706 tweets with the hashtags related to "NHK Kohaku-Uta- gassen "in 2011/2012, the effectiveness of the proposed method compared with the method used morphological analysis is shown. |
