Finding Diachronic Objects of Drifting Descriptions by Similar Mentions

In this paper, we propose that document sets consist of two types, drift descriptions that record actions on diachronic objects that could be regarded as the same over time and diversity descriptions that record actions on different objects. This research finds diachronic objects to extract a document subset of drift descriptions. We assumed that a diachronic object would be mentioned similarly and have different time-distribution appearances. Consequently, we proposed a method to find words that represent diachronic objects by similar mentions and applied it to three different document sets. The results show that it is possible to extract document objects for drift descriptions.
