    摘要： Methods, systems, and computer-readable media for representing and querying positional information for a hierarchical document (such as an XML document) are disclosed. In one set of embodiments, at least one word in the hierarchical document is associated with one or more word positions, and at least one element in the hierarchical document is associated with one or more word position ranges. The word positions and word position ranges are analyzed to determine whether a particular word or phrase is a direct or indirect descendant of a particular element in the hierarchical document. In various embodiments, the word positions are indexed in a first index and the word position ranges are indexed in a second index. Thus, the analysis may be efficiently performed by intersecting the first and second indexes. In further embodiments, the word position ranges may be encoded in a space efficient format for storage or transmittal.

    摘要： Embodiments of the present invention include storing a plurality of subtrees in a database, the plurality of subtrees representing one or more structured documents. At least one subtree has a birth timestamp indicating a time at which the at least one subtree was created. If a subtree has been obsoleted, the subtree has a death timestamp indicating a time at which the subtree was obsoleted. Embodiments further include receiving a database query comprising a query string and a query timestamp, the query timestamp indicating a historical time for which the query is to apply, and determining an intermediate result list of subtrees. The intermediate result list is filtered to generate a final result list responsive to the database query, the filtering comprising removing subtrees that do not have a birth timestamp, have a birth timestamp later than the query timestamp, or have a death timestamp earlier than the query timestamp.

    摘要： A method for loading information into a tree structured database includes receiving a document and forming a top-down tree characterizing the document. Leaf nodes in the top-down tree are identified. Bottom-up indices are formed for the leaf nodes, where the bottom-up indices characterizes paths from selected leaf nodes to a root node of the top-down tree. The top-down tree and bottom-up indices are stored as separately searchable entities in the tree structured database.

    摘要： One aspect of the present invention is a system for classifying element nodes in a subtree-structured XML database. The XQE structural-textual classification system is sensitive to both the textual resemblance between document elements as well as the structural resemblance between document elements. The XQE structural-textual classification system might use the XQE parent-child index described in Lindblad II-A for the purpose of forming vectors of “terms” which encode both the structural and the textual content of XML elements. The element vectors are processed by a classifier to create class prototype vectors which can be used to classify elements as they are added to the database.
