Abstract: A method for computing similarity between paths includes extracting corpus statistics for triples from a corpus of text documents, each triple comprising a predicate and respective first and second arguments of the predicate. Documents in the corpus are clustered to form a set of clusters based on textual similarity and temporal similarity. An event-based path similarity is computed between first and second paths, the first path comprising a first predicate and first and second argument slots, the second path comprising a second predicate and first and second argument slots, the event-based path similarity being computed as a function of a corpus statistics-based similarity score which is a function of the corpus statistics for the extracted triples which are instances of the first and second paths, and a cluster-based similarity score which is a function of occurrences of the first and second predicates in the clusters.

Abstract translation: 用于计算路径之间的相似性的方法包括从文本文档的语料库中提取三元组的语料库统计量，每个三元组包括谓词以及谓词的相应的第一和第二参数。 基于文本相似性和时间相似性，语料库中的文档被聚类以形成一组聚类。 在第一和第二路径之间计算基于事件的路径相似性，所述第一路径包括第一谓词和第一和第二参数时隙，所述第二路径包括第二谓词以及第一和第二参数时隙，所述基于事件的路径相似性被计算 作为基于语料库统计的相似性得分的函数，其是作为第一和第二路径的实例的提取的三元组的语料库统计的函数，以及基于群集的相似性得分，其是第一和第二路径的出现的函数 集群中的第二个谓词。

Abstract: A method for extraction of events includes performing linguistic processing on a collection of text documents to identify predicates and respective arguments of the predicates and performing temporal processing on the collection of documents to normalize referential dates. A query is received which includes a topic and date information which defines a date range. A collection of excerpts from the collection of documents is identified, each excerpt including an argument which is based on the topic and a normalized reference to a date which matches the defined date range. A plurality of sets of events in the collection of excerpts is identified, each set of events including a plurality of the excerpts in the collection that are linked together by entailment relationships.

Abstract translation: 一种用于提取事件的方法包括对文本文档的集合执行语言处理，以识别谓词的谓词和各自的参数，并对文档的收集执行时间处理以使引用日期正常化。 收到一个包含定义日期范围的主题和日期信息的查询。 识别收集文档的摘录集，每个摘录包括基于主题的参数和与定义的日期范围匹配的日期的归一化引用。 识别摘录集合中的多组事件，每组事件包括集合中的多个摘录，这些摘录通过内容关系链接在一起。
