    摘要： A computerized method of ordering document clusters for presentation after browsing a corpus of documents that presents document clusters in a logical fashion in the absence of any indication of the computer user's interests. The method begins by grouping the corpus into a plurality of clusters, each having a centroid and including at least one document. Next, for each cluster a degree of similarity between that cluster and every other cluster is by finding a dot product between each cluster centroid and every other cluster centroid. The similarity information is then used to determine an order of presentation for the plurality of in a way that maximizes the degree of similarity between adjacent clusters.

    摘要： A method of filtering according to text genre the results of a topic search of a heterogeneous corpus of untagged, machine-readable texts. Because each text of the corpus has a topic and a text genre, the corpus includes multiple text genres and covers multiple topics. According to the method, a processor first searches the corpus for a first multiplicity of texts that have a first topic. Next, the processor identifies a first set of texts of the first multiplicity that are instances of a first text genre and identifies a second set of texts of the first multiplicity that are instances of a second text genre. Finally, the processor identifies to a computer user the first multiplicity of texts in an order based upon the first text genre and second text genre.

    摘要： Arbitrarily large document collections are processed by expanding a focus set having at least one initial metadocument into a plurality of subsequent metadocuments. 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.

    摘要： Scatter-Gather is a computer based document browsing method which operates in time proportional to a number of documents in a target corpus. The Scatter-Gather method includes: preparing an initial ordering of the corpus using, for example, an off-line computational method; determining a summary of the initial ordering of the corpus for interactive utility; and providing a further ordering of the corpus using, for example, an on-line non-deterministic method. The step of an off-line preparation of an initial ordering of a corpus is non-time-dependent, thus an accurate initial ordering is prepared. The step of determining a summary includes determining a summary for presentation to a user without scrolling on a CRT. The step of providing a further ordering includes truncated group average agglomerate clustering, merging disjointed document sets, center finding, assign-to-nearest and other refinement methods.

    摘要： An information retrieval system and method are provided in which an operator inputs one or more query words which are used to determine a search key for searching through a corpus of documents, and which returns any matches between the search key and the corpus of documents as a phrase containing the word data matching 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 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.

    摘要： A method of automatically generating document extracts. The method makes use of feature value probabilities generated from a statistical analysis of manually generated summaries to extract the same set of sentences an expert might. The method is based upon an iterative approach. First, the computer system designates a sentence of the document as a selected sentence. Second, the computer system determine values for the selected sentence of each feature of a feature set. Third, the computer system increases a score for the selected sentence based upon the value of the feature for the selected sentence and upon the probability associated with that value. Fourth, after scoring all of the sentences of the document the computer system, the computer system selects a subset of the highest scoring sentences to be extracted.

    摘要： Regions of a document such as sentences and blocks of sentences are scored and classified based upon their scores. An abstract of the document can be formed from the classified sentences. Sentences are classified by the use of words classified as stop words and vanish words. Sentences are scored based on the number of stop words and the number of strings of connected stop words, called stop-word runs, contained in the sentence. Passionate sentences, which usually contain information which the writer has strong feelings about, such as joy, admiration, or sadness, are identified. This method can also select sentences that are contrapassionate, which the writer may either have to strengthen or have inserted to complete the record and provide continuity or information.
