| 中文简介: |  此演讲探讨了20年来网络搜索体验的发展以及它们对基础架构的影响。早期的网络搜索代表了从经典信息检索到Web的各种方法的改编。在本世纪初，关注点转移到对查询的需求进行分类，无论是导航，信息还是事务性查询。引擎开始根据需要定制其体验。下一个变化是由于人们认识到大多数查询都包含名词短语，从而导致了知识表示的构建，查询可以从中提取并传递有关查询中名词的信息。最近，三种趋势代表了超越这些“名词引擎”的下一步：（1）“无查询引擎”已经开始基于用户的上下文提供满足用户需求的信息，而没有明确的查询； （2）搜索引擎已经积极开始协助名词查询背后的动词的用户任务； （3）越来越多地使用语音识别正在改变查询的分布。 |
| 课程简介: | This talk examines the evolution of web search experiences over 20 years, and their impact on the underlying architecture. Early web search represented the adaptation of methods from classic Information Retrieval to the Web. Around the turn of this century, the focus shifted to triaging the need behind a query - whether it was Navigational, Informational or Transactional; engines began to customize their experiences depending on the need. The next change arose from the recognition that most queries embodied noun phrases, leading to the construction of knowledge representations from which queries could extract and deliver information regarding the noun in the query. Most recently, three trends represent the next step beyond these "noun engines": (1) "Queryless engines" have begun surfacing information meeting a user's need based on the user's context, without explicit querying; (2) Search engines have actively begun assisting the user's task at hand - the verb underlying the noun query; (3) increasing use of speech recognition is changing the distribution of queries. |
