Improving text search quality by exploiting organizational information

摘要

The present invention relates to method and system for electronic Information Retrieval (IR) applied for an electronic search in a given search environment, in which method a predetermined search pool of documents is crawled (110), and retrieved documents are indexed (230) and ordered by a given ranking procedure (250) according to a given ranking criterion comprising search items defined by a searching person. In order to improve electronic retrieval systems for less-linked information sources, where a searched document can be mapped to an element of the organizational structure of an enterprise associated with said environment, the following steps are proposed:
a) at indexing time, mapping (225) a search document to at least one element of the organizational structure of an enterprise associated with said environment,
b) at query time, associating (245) a querying user with at least one element of the organizational structure of said enterprise,
c) comparing the organizational information of the search document and that one of the querying user, and
d) providing a higher rank to retrieved documents, which have a closer organizational relation compared to documents with a less close relation.
