Mining Temporal Patterns of Technical Term Usages in Bibliographical Data

Abstract : In text mining framework, data-driven indices are used as importance indices of words and phrases. Although the values of these indices are influenced by usages of terms, many conventional emergent term detection methods did not treat these indices explicitly. In order to detect research keys in academic researches, we propose a method based on temporal patterns of technical terms by using several data-driven indices and their temporal clusters. The method consists of an automatic term extraction method in given documents, three importance indices from text mining studies, and temporal patterns based on results of temporal clustering. Then, we assign abstracted sense of the temporal patterns of the terms based on their linear trends of centroids. Empirical studies show that the three importance indices are applied to the titles of four annual conferences about data mining field as sets of documents. After extracting the temporal patterns of automatically extracted terms, we compared the emergent patterns and one of the keyword of this article between the four conferences.
