| Abstract(in English) | We propose a machine learning based method that identifies an equivalence relation between sentences in different newspaper articles on a topic. We showed that our method, which divided the corpus into several classes by sentence similarity and learned a classifier, yielded a superior result than without dividing it. In addition, compared with the number of total sentence pairs, the number of sentence pairs in an equivalence relation is too small in a relatively less similar class. Therefore, the classifier sometimes cannot identify equivalence relations. To solve this problem, we use "relations similar to equivalence" that describe a same content more briefly or in more detail in different newspaper articles. We also propose a two-stage method that first identifies a coarse class that includes both an equivalence relation and "relations similar to equivalence", and then identifies an equivalence relation from a coarse class. We showed that high accuracy was yielded by combining these two methods. |
