摘要
介绍现阶段情报检索研究中的几个前沿问题,包括自然语言检索、跨语言检索、智能信息检索、基于语义的图像和视频检索及检索系统评价研究的最新发展情况。语言、智能和语义等问题相互关联,近年来又一同推动着信息检索的发展。检索评价研究也有针对性地引导着情报检索的发展方向。结语部分论述这些问题在情报检索前沿发展中的本质联系及未来的发展方向。
The paper introduces some advanced topics and their up-to-date developments, including natural language retrieval, cross-language information retrieval （CLIR）, intelligent information retrieval, semantic-based information retrieval and evaluation. Language, intelligence and semantic are closely related and together lead the development of IR. Research on system evaluation also leads the direction of IR development and becomes more accurate. The paper at last discusses the essential relations of these problems in IR and further developing directions.
