摘要： The method includes receiving, by one or more processors, an initial query term. The method further includes generating, by one or more processors, an expanded query based on the received initial query term and one or more related terms to the received initial query. The method further includes determining, by one or more processors, weights corresponding to terms in the received initial query term and the generated expanded query term based on a predicted effect on query performance.

摘要： A method, including submitting, to a search engine, a first query including, and receiving, in response to the first query, a first list including first results, each of the first results having a respective first ranking. Keywords are derived from the first query, and for each keyword, a respective second query is submitted to the search engine, the respective second query including the first query term and the derived keyword. In response to each of the respective second queries, a respective second list including respective second results is received, each of the respective second results having a second ranking and a corresponding first result, and for each given second result, one or more stability scores are computed based on the second ranking of the given second result and the first ranking of the corresponding first result. The second results are ranked based on their respective one or more stability scores.
摘要翻译：一种方法，包括向搜索引擎提交包括响应于第一查询并且接收响应于第一查询的第一列表的第一列表，其包括第一结果，第一结果中的每一个具有相应的第一排名。关键字从第一查询导出，并且对于每个关键字，将相应的第二查询提交给搜索引擎，相应的第二查询包括第一查询项和派生关键字。响应于每个相应的第二查询，接收包括相应的第二结果的相应的第二列表，每个相应的第二结果具有第二排名和相应的第一结果，并且对于每个给定的第二结果，一个或多个稳定性分数是基于给定第二结果的第二排序和对应的第一结果的第一排序来计算。第二个结果根据它们各自的一个或多个稳定性得分进行排名。

摘要： Machine logic that traces increases (or decreases) in query drift by performing the following steps: retrieving a first response list responding to a first query; retrieving a second response list responding to a second query, wherein the second query is based, at least in part, on a topic related to the first query; determining a set of scores for each of the first response list and the second response list, calculating a normalized query commitment (“NQC”) for each of the first response list and the second response list; and responsive to determining that a ratio representing a relative difference between the NQC for the first response list and the NQC for the second response list is above a predetermined threshold, determining to use the second response list to respond to the first query.

摘要： Method and apparatus for training and using a classifier for words. Embodiments include receiving a first plurality of sentences comprising a first word that is associated with a class and a second plurality of sentences comprising a second word that is not associated with the class. Embodiments include training a classifier using positive training data for the class that is based on the first plurality of sentences and negative training data for the class that is based on the second plurality of sentences. Embodiments include determining a measure of correlation between a third word and the class by using a sentence comprising the third word as an input to the classifier. Embodiments include using the measure of correlation to perform an action selected from the following list: selecting content to provide to a user; determining an automatic chat response; or filtering a set of content.
