This paper proposes a method that mines subtopics using the head-modifier relation and co-occurrence of users' intents from web documents in Japanese. We extracted subtopics using the simple patterns based on the head-modifier relation between the query and its adjacent words, and returned the ranked list of subtopics by the proposed score equation. We re-ranked subtopics according to the intent co-occurrence measure. Our method achieved good performance than the baseline methods and suggested queries from the major web search engine. The results of our method will be useful in various search scenarios, such as query suggestion and result diversification. © 2013 Springer-Verlag.
