ISCAS: Text Retrieval in NTCIR Workshop II
نویسندگان
چکیده
In NTCIR workshop II, we participated in both the Chinese and English-Chinese Information Retrieval tracks in an automatic way. In the Chinese Information Retrieval (CHIR) track, to improve the effectiveness of the word-based retrieval system, a new method, named PM-based (PM: Proximity and Mutual information) method, is designed and introduced into the system. Employing the proximity and mutual information of the term pairs, the effectiveness of the PM-based method is expected to outmatch that of the word-based method in processing dictionary-uncovered words. In the English-Chinese Information Retrieval (ECIR) track, we mainly focused our efforts on how to disambiguate the Chinese meanings of each English query word when it is translated with a given English-Chinese bilingual dictionary, and then used the word-based Chinese text retrieval system to carry out the ECIR task.
