Suggesting Japanese Subject Headings using Web Information Resources
نویسندگان
چکیده
It is well-known that suggesting subject headings according to user queries is useful for subject searches (e.g., the MeSH database for MEDLINE (“MeSH databse,” n.d.), RedLightGreen (“RedLightGreen,” n.d.)). However, few systems suggest subject headings for OPACs in Japan. Some systems (e.g. “National Diet Library NDL-OPAC,” n.d.), which offer users a function that retrieves subject headings, are based on pattern matching algorithms, and they usually fail to suggest a subject heading when there is no hit.

متن کاملSuggesting Subject Headings Using Web Information Sources
We proposed a method that suggests subject headings based on user queries when a pattern-matching algorithm fails to locate subject searches for Online Public Access Catalogs (OPAC). We combined information obtained from Wikipedia, Amazon, and Google for query expansion. Our method has two main advantages: (1) availability for any library without customizing OPACs, and (2) ability to suggest su...
