航天信息智能搜索引擎技术

Intelligent search engine technology of aerospace information

航天信息智能搜索技术是根据用户需求对航天信息进行及时分发的关键,是航天信息共享应用的核心技术之一。多源航天信息的多维、异构、高动态等特征导致难以使用传统的搜索引擎进行航天信息的检索,很难直接使用成熟的商业搜索引擎和数据挖掘算法来实现高动态和多维数据的检索。针对上述问题,提出了航天信息智能搜索引擎架构,并研究了关键技术解决方案。

The intelligent search engine technology of aerospace information is the crux of distributing aerospace information timely aecording to the requirements of users, and it is one of the key technologies of sharing aerospace information. The feature of multi-dimension, heterogeneity, high-dynamic of multi-source information leads to the problem that it is hard to use the traditional search engine to search the aerospace in- formation. In addition, it is difficult to use the mature business search engine and data mining algorithms to search the high-dynamic and multi-dimension data. Aiming at the problems above, the architecture of intelligent search engine is proposed and the solution of the key technology is researched.
