中文简介:
虽然用户对搜索的依赖持续增加,但用户满意度并没有提高。这部分是因为搜索是困难的,部分是因为用户的要求越来越高,使得搜索超越了传统的信息检索范围。我们的研究揭示了三个关键问题的搜索:不精确的结果,需要查询细化,需要支持复杂的任务和决策。语义技术可以通过提供对核心搜索结果的改进,以及支持更丰富的用户体验(如分面导航、以实体为中心的体验、任务完成和决策工具)来帮助解决这些问题。
课程简介: While users dependence on search continues to increase, user satisfaction is not improving. This is partly because search is hard, and partly because users are becoming more demanding and pushing search beyond the traditional scope of information retrieval. Our research reveals three key problems of search: imprecise results, need for query refinement, and need to support complex tasks and decisions. Semantic technologies can help address these problems by providing improvements to core search results and also through enabling richer user experiences such as faceted navigation, entity-centered experiences, and task completion and decision tools.
