摘要

PPROBLEM TO BE SOLVED: To acquire paraphrasing expression speaking the same meaning content by different expression from a document group without needing syntax analysis and without giving some example in a specific relation in advance. PSOLUTION: A cooccurrence word pair context collection part 12 collects contexts containing a pair of optional cooccurrence words from the document group housed in a document group DB1 and stores individual contexts in a cooccurrence word pair context DB2 by each pair of the cooccurrence words. A context vector generation part 14 obtains the word frequency of words constituting the individual contexts corresponding to each pair of cooccurrence words, calculates a weight, and stores a context vector in a context vector DB4. A context vector similarity calculation part 15 obtains all the similarities between two context vectors. A cooccurrence word pair clustering part 16 clusters a pair of cooccurrence words of high similarity between the context vectors. A relation label acquiring part 17 acquires words expressing respective clusters, and an intra-cluster context selection part 18 selects a context containing the word as a paraphrased expression from the DB2.

要解决的问题：从文档组中以不同的表达获取具有相同含义内容的释义表达，而无需语法分析，也无需事先给出特定关系的示例。

解决方案：同现词对上下文收集部分12从文档组DB1中容纳的文档组中收集包含一对可选的同现词的上下文，并按每对同现词将各个上下文存储在同现词对上下文DB2中。上下文向量生成部14获得构成与每对同现词对相对应的各个上下文的词的词频，计算权重，并将上下文向量存储在上下文向量DB4中。上下文向量相似度计算部分15获得两个上下文向量之间的所有相似度。同现词对聚类部分16将上下文向量之间的高度相似的一对同现词聚类。关系标签获取部分17获取表达各个聚类的词，并且集群内上下文选择部分18从DB2中选择包含该词的上下文作为释义表达。
