Abstract: Systems and methods for returning results to a query based upon topic are disclosed herein. Aspects disclosed can be particularly useful when searching for videos or other media content for which associated textual information are generally relatively sparse compared to other types of content. Text associated with the query can be semantically associated with various domain topics by mapping one or more words included in the query to one or more domain topics based upon a conditional probability of the domain topic given the query. A set of results can be identified based upon a conditional probability of the result given the domain topic.

Abstract translation: 本文公开了用于将结果返回到基于主题的查询的系统和方法。 当搜索与其他类型的内容相比较相关文本信息通常相对稀疏的视频或其他媒体内容时，所公开的方面可以是特别有用的。 与查询相关联的文本可以通过基于给定查询的域主题的条件概率将查询中包括的一个或多个词映射到一个或多个域主题来语义地与各种领域主题相关联。 可以基于给定域主题的结果的条件概率来识别一组结果。
