摘要 提出了跨媒体搜索引擎TCSE,利用标注文档进行文本、图片、音频和视频资源的统一表示,并采用创新的主题感知查询扩展算法,得到用户的隐含查询意图。实验结果表明,利用TCSE进行查询,可以实现多种类型媒体资源同时检索,有效地提高了信息检索准确度。 A novel tourism cros:s-media search engine, called TCSE for short, has been developed. All the media type resources have a uniform representation using annotation file and users' query implication intention are quickly identified using a novel subject-aware query expansion algo-rithm. To sum up, TCSE can implement a variety of media information retrieval function simul- taneously and effectively improve the quality of information retrieval.
