Qualifier Mining for NTCIR-INTENT.
Hai-Tao Yu, Fuji Ren, Song Liu · 2011
We participated the Subtopic Mining subtask of NTCIR-9 INTENT task. Query Log is used as the primary resource to mine latent subtopics. Through analysis of query log, we observed that queries describing similar information needs will use a similar group of qualifiers, which may also frequently occur together within queries. We introduced the concept of qualifier graph for subtopic mining. To solve the sparseness problem, the search snippets returned by web search engines are used. The experiment results show that it is reasonable to make use of qualifier to mine latent subtopics.
