    Abstract: A processor implemented method of identifying the genre of a machine readable, untagged text. The processor implemented method begins by generating a cue vector from the text, which represents occurrences in the text of a first set of nonstructural, surface cues, which are easily computable. Afterward, the processor determines whether the text is an instance of a first text genre using the cue vector and a weighting vector associated with the first text genre.

    Abstract translation: 处理器实现的识别机器可读，无标记文本的流派的方法。 处理器实现的方法首先从文本中生成一个提示矢量，该提示矢量表示第一组非易失性表面提示的文本中的出现，这些提示很容易计算。 之后，处理器使用提示矢量和与第一文本流派相关联的加权矢量来确定文本是否是第一文本流派的实例。

    Abstract: Arbitrarily large document collections are processed by expanding a focus set having at least one initial metadocument (82) into a plurality of subsequent metadocuments (83,84,85,86). The number of subsequent metadocuments is approximately equal to a predetermined maximum number. The subsequent metadocuments are then clustered into a predetermined number of new metadocuments, which are summarized and presented to a user. The focus set is redefined to include only user-selected new metadocuments.

    Abstract translation: 通过将具有至少一个初始元文件（82）的焦点集扩展到多个后续元文件（83,84,85,86）中来处理任意大的文档集合。 后续元文件的数量近似等于预定的最大数量。 随后的元文件然后被聚集成预定数量的新的元文件，其被汇总并呈现给用户。 焦点集被重新定义为仅包括用户选择的新的元文件。

    Abstract: A method of automatically generating feature probabilities that allow later automatic generation of document extracts. The computer system generates the probabilities by analyzing each document a document at a time. First, the computer system designates one of the documents as a selected document. Next, the computer system analyzes each sentence of the selected document to determine the value of the paragraph feature and the value of the uppercase feature. The computer system repeats this effort for each document of the document corpus. Afterward, the number of occurrences of each value of each feature is calculated and is used to calculate feature value probabilities for all of the features.

    Abstract: An information retrieval system and method are provided in which an operator inputs (110) one or more query words which are used to determine a search key (120) for searching (130) through a corpus of documents, and which returns ( 140) any matches between the search key and the corpus of documents as a phrase containing the word data matching the search key (the query word(s)), a non-stop (content) word next adjacent to the matching word data, and all intervening stop-words between the matching word data and the next adjacent non-stop word. The operator, after reviewing one or more of the returned phrases can then use one or more of the next adjacent non-stop-words as new query words to reformulate the search key ( 150, 160, 170) and perform a subsequent search through the document corpus. This process can be conducted iteratively, until the appropriate documents of interest are located. The additional non-stop-words from each phrase are preferably aligned with each other (e.g., by columnation) to ease viewing of the " new" content words.
