Query Expansion Using Wikipedia and a Concept Base in Cross-language Information Retrieval

The present paper describes the use of online free language resources for translating and expanding queries in CLIR （cross-language information retrieval）. In a previous study, we proposed method queries that were translated by two machine translation systems on the Language Gridem. The queries were then expanded using an online dictionary to translate compound words or word phrases. A concept base was used to compare back translation words with the original query in order to delete mistranslated words. In order to evaluate the proposed method, we constructed a CLIR system and used the science documents of the NTCIR1 dataset. The proposed method achieved high precision. However~ proper nouns （names of people and places） appear infrequently in science documents. In information retrieval, proper nouns present unique problems. Since proper nouns are usually unknown words, they are difficult to find in monolingual dictionaries, not to mention bilingual dictionaries. Furthermore, the initial query of the user is not always the best description of the desired information. In order to solve this problem, and to create a better query representation, query expansion is often proposed as a solution. Wikipedia was used to translate compound words or word phrases. It was also used to expand queries together with a concept base. The NTCIRI and NTCIR 6 datasets were used to evaluate the proposed method. In the proposed method, the CLIR system was implemented with a high rate of precision. The proposed syst had a higher ranking than the NTCIRI and NTCIR6 participation systems.

探索王国维词学体系的另一个维度——《词录》与王国维“为学三变”的文献学取向

作为中国早期词学专科目录著作,《词录》是王国维迈入“文学时代”、顺利实现学术转型的第一批具体成果。这部词学目录与《人间词》、《人间词话》、《唐五代二十一家词辑》等书产生“协同”作用,形成了一个创作—理论—文献“三维一体”的词学体系,其学术价值集中体现在与《人间词》的词创作、《人间词话》的词学理论建构之间的互补上,真实反映了他对于“可爱”且“可信”的学术境界的追求与构拟,更凸现了其文化心态的转变。
