摘要： A phrase recognition method breaks streams of text into text "chunks" and selects certain chunks as "phrases" useful for automated full text searching. The phrase recognition method uses a carefully assembled list of partition elements to partition the text into the chunks, and selects phrases from the chunks according to a small number of frequency based definitions. The method can also incorporate additional processes such as categorization of proper names to enhance phrase recognition. The method selects phrases quickly and efficiently, referring simply to the phrases themselves and the frequency with which they are encountered, rather than relying on complex, time-consuming, resource-consuming grammatical analysis, or on collocation schemes of limited applicability, or on heuristical text analysis of limited reliability or utility.
摘要翻译：短语识别方法将文本流分解为文本“块”，并选择某些块作为自动全文搜索有用的“短语”。短语识别方法使用仔细组装的分区元素列表来将文本划分成块，并且根据少量基于频率的定义从块中选择短语。该方法还可以包括额外的过程，例如分类专有名称以增强短语识别。该方法可以快速有效地选择短语，仅仅参考短语本身及其遇到的频率，而不是依赖于复杂，耗时，资源消耗的语法分析，或者是适用性有限的搭配方案，或者是有意义的有限可靠性或效用的文本分析。
