| Abstract(in English) | Chat dialogue systems need to have a topic transition function in order not to let users get tired. In this paper, we focus on association as a method to decide topics after topic transition, and study acquisition of associative words that realize natural topic transition. In order to clarify properties and conditions of association used for topic transition, we collect associative words by free association with topic words as stimulus words. We also collect related words that have large cosine similarity with topic words based on word vectors acquired using word2vec. Next, we classify the collected associative words and related words according to the semantic relation with topic words, and compare them. Then we conduct evaluation experiments to investigate whether these associative words and related words are suitable for topic transition in dialogue, and consider a method to automatically obtain associative words that realize natural topic transition. |
