    • A statistical thesaurus is built dynamically, from the same text collection that is being searched, allowing improved generation of expanded query terms. The thesaurus is dynamic in that thesaurus records are collected, ranked, accessed, and applied dynamically. Thesaurus "records" are actually formed as indexed documents arranged in "collections". The collections are preferably distinguished based on text source (court cases versus news wires versus patents, and so forth). Each record has terms assembled in indexed groups (or segments) which inherently reflect a ranking based on relevance to an initial query. After an initial query is received, the appropriate collection(s) of records may be searched by a conventional search and retrieval engine, the searches inherently returning records ranked by degree of relevance due to the record indexing scheme. A record ranking scheme avoids contamination of relevant records by less relevant records. The record selection and the expansion query term generation processes are each divided into parallel threads. The separate threads correspond to respective text sources to enable the improved expansion query term generation to be provided in real time.
    • 统计词库是从正在搜索的相同文本集合中动态构建的,允许改进扩展查询词的生成。 词库是动态的,因为词典记录被收集,排序,访问和动态应用。 词典“记录”实际上是作为“集合”中排列的索引文档形成的。 收藏品最好根据文本来源(法庭案件与新闻线对专利等)区分开来。 每个记录都有汇编在索引组(或分段)中的条款,这些组根据初始查询的相关性固有地反映排名。 在接收到初始查询之后,可以通过常规搜索和检索引擎来搜索适当的记录集合,由于记录索引方案,搜索本质上返回由相关程度排列的记录。 记录排名计划避免相关记录的污染较少相关记录。 记录选择和扩展查询项生成过程分为并行线程。 单独的线程对应于相应的文本源,以使实时地提供改进的扩展查询词生成。
