摘要： A method and system for assessing the quality of one or more search engines are provided. The method and system monitor reformulation sessions by users (201) of a search engine (308, 402, 403) by retrieving data from a query log (307, 407, 408), wherein a reformulation session is a series of at least two queries to a search engine (308) issued by a user (201) to satisfy a single information need. The method and system then determine a reformulation session parameter for the search engine (308, 402, 403) and analyse the reformulation session parameter. The reformulation session parameter may be a rate of query reformulations in a reformulation session or a reformulation session duration. Analysing the reformulation session parameter for a single search engine may determine if the parameter changes with time or may determine the parameter with different settings in a single search engine. Analysing the reformulation session parameter for two or more search engines includes comparing the parameters of the two or more search engines to measure the search quality. The analysis can be used to control the operation of one or more search engines.
摘要翻译：提供了一种用于评估一个或多个搜索引擎的质量的方法和系统。所述方法和系统通过从查询日志（307,407,408）中检索数据来监视用户（201）的搜索引擎（308,402,403）的重新制定会话，其中重新配置会话是一系列至少两个查询到由用户（201）发布以满足单个信息需求的搜索引擎（308）。方法和系统然后确定搜索引擎（308,402,403）的重新配置会话参数，并分析重新配置会话参数。重新配置会话参数可以是重新配置会话或重新配置会话持续时间中的查询重新设置的速率。分析单个搜索引擎的重新配置会话参数可以确定参数是否随时间变化，或者可以在单个搜索引擎中确定具有不同设置的参数。分析两个或多个搜索引擎的重新配置会话参数包括比较两个或多个搜索引擎的参数以测量搜索质量。该分析可用于控制一个或多个搜索引擎的操作。

摘要： A method for searching a document collection includes providing an index of terms indicating the documents in which the terms appear. A first statistical distribution of each of at least some of the terms in the index and a second statistical distribution of each of at least some of the categories are estimated a over the documents in the collection. A query including one or more of the terms and a category restriction referring to at least one of the categories is accepted. A modified term distribution is produced by operating on the first statistical distribution of at least one of the terms in the query using the second statistical distribution, responsively to the category restriction. The query is applied to the index to return a response, in which occurrences of the at least one of the terms are scored responsively to the modified term distribution.

摘要： A method and system for analyzing a document set (202, 420) are provided. The method includes determining a set of terms (312) from the terms of the document set that minimizes a distance measurement (405) from the given set of documents (420). The method includes using a greedy algorithm to build the set of terms incrementally, at each stage finding a single word that is closest to the document set (202, 420). The set of terms is evaluated to assess the ability to find the document set (202, 420). The set of terms are compared with expected terms to evaluate the ability to find the document set (202, 420). A measure of the ability to find a document set (202, 420) is provided by computing a distance measure (403) between a document set and an entire collection.
