摘要： Words having selected characteristics in a corpus of documents are found using a data processor arranged to execute queries. Memory stores an index structure in which entries in the index structure map words and marks for words having the selected characteristics to locations within documents in the corpus. Entries in the index structure represent words and other entries represent marks with the location information of a marked word. The entries for the marks can be tokens coalesced with prefixes of respective marked words or adjacent. A query processor forms a modified query by adding a mark for a word to the query. The processor executes the modified query.

摘要： The present invention involves a novel form and methods for creating and using such forms. These forms are summaries (hereinafter "document surrogates") of associated objects, such as original documents, processes, or their copies, stored in a document processing system. A document surrogate made in accordance with the principles of the present invention comprises at least one sheet of a information storing substrate material that has a human readable area and a machine readable area. The human readable area may contain at least one area of material which summarizes the associated object. Such a summary may either be made manually by the user or created automatically by the document processing system. The machine readable area comprises a document reference code that is readable and recognizable by the document processing system. The code is located by the system and recognized from an image of the entire page. The reference code encodes an indicator to the storage location of the associated object. Upon encountering a document surrogate, the system may interpret the surrogate to be the equivalent of its associated object and uses the indicator to access the appropriate object. A mechanism may be provided to the system to either enable or disable this equivalence. If disabled, the system would treat the document surrogate like a typical page in a document.
摘要翻译：本发明涉及用于创建和使用这种形式的新颖形式和方法。这些形式是存储在文件处理系统中的相关对象（例如原始文档，过程或其副本）的摘要（以下称为“文档替代”）。根据本发明的原理制造的文件替代品包括至少一张具有可读区域和机器可读区域的存储基板材料的信息。人类可读区域可以包含总结相关对象的材料的至少一个区域。这种总结可以由用户手动进行或由文档处理系统自动创建。机器可读区域包括由文档处理系统可读和可识别的文档参考代码。代码由系统定位，并从整个页面的图像中识别。参考代码将指示符编码到相关对象的存储位置。在遇到文档代理时，系统可以将代理解释为等效于其关联对象，并使用指示符来访问适当的对象。可以向系统提供机制以启用或禁用此等效性。如果禁用，系统将像文档中的典型页面一样处理文档代理。

摘要： A node-link structure is displayed within a display area, having a narrow rectangular shape with an edge along one side acting as a horizon of a hyperbolic space half-plane. Lower level node features that share a parent node feature have centers of area positioned on the display in order along a line parallel with the horizon, with sufficiently similar spacings along an axis perpendicular to the horizon from the region around a parent node feature, and with sufficiently similar spacings in a dimension parallel to the horizon from adjacent node features along the line, that the lower level node features sharing the parent node feature are perceptible as a group of related node features. The half-plane model with compression is used for layout of the node-link data, and the hyperbolic layout data is mapped to a Euclidean space for display.

摘要： A method and apparatus for processing a document image, using a programmed general or special purpose computer, includes forming the image into image units, and at least one image unit classifier of at least one of the image units is determined, without decoding the content of the at least one of the image units. The classifier of the at least one of the image units is then compared with a classifier of another image unit. The classifier may be image unit length, width, location in the document, font, typeface, cross-section, the number of ascenders, the number of descenders, the average pixel density, the length of the top line contour, the length of the base contour, the location of image units with respect to neighboring image units, vertical position, horizontal inter-image unit spacing, and so forth. The classifier comparison can be a comparison with classifiers of image units of words in a reference table, or with classifiers of other image units in the document. Equivalent classes of image units can be generated, from which word frequency and significance can be determined. The image units can be determined by creating bounding boxes about identifiable segments or extractable units of the image, and can contain a word, a phrase, a letter, a number, a character, a glyph or the like.

摘要： An information retrieval system having a secondary content analysis engine for use on collections of documents. Such collections of documents dynamically arise as a result of queries one or more, possibly distal, information sources. The secondary content analysis engine resides on an Information Access client computer system and allows the user to: 1) iteratively refine queries in more powerful ways than typically supported by relevance feedback or other query modification methods, 2) browse a medium-sized collection of documents (on the order of 1000 items) in more effective ways than is traditionally possible or 3) obtain more information for increasing user understanding of the collection.

摘要： A workspace data structure, such as a window hierarchy or network, includes functional data units that include data relating to workspace functionality. These functional data units are associated with data units corresponding to the workspaces such that a functional data unit can be replaced by a functional data unit compatible with a different set of functions without modifying the structure of other data units. Each workspace data unit may have a replaceably associated functional data unit called an input contract relating to its input functions and another called an output contract relating to its output functions. A parent workspace's data unit and the data units of its children may together have a replaceably associated functional data unit, called a windowing contract, relating to the windowing relationship between the parent and the children. The data structure may also include an auxiliary data unit associated between the data units of the parent and children windows, and the windowing contract may be associated with the auxiliary data unit. The contracts can be accessed and replaced by a processor in a system that includes the data structure. The contracts can be instances of classes in an object-oriented programming language, and can be replaceably associated by pointers associated with the system objects. Alternatively, a contract can be replaceably associated through dynamic multiple inheritance, with the superclasses of each workspace class including one or more contract classes such that changing the class of an instance of a workspace class serves to replace the contract.

摘要： A system for extracting and analyzing information from a collection of linked documents at a locality to enable categorization of documents and prediction of documents relevant to a focus document. The system obtains and analyzes topology, usage and path information from for a collection at a locality, e.g. a web locality on the world wide web. For categorization, document meta information is represented as document vectors. Predefined criteria is applied to the document vectors to create lists of "similar" types of documents. For relevance prediction, networks representing topology, usage path and text similarity amongst the documents in the collection are created. A spreading activation technique is applied to the networks starting at a focus document to predict the documents relevant to the focus document. Using category and relevance prediction information, tools can be built to enable a user to more efficiently traverse through the collection of linked documents.
