Abstract: Systems and methods of comparing structured documents are disclosed. From/to source documents are first represented by their respective from/to XML forms based on a predetermined schema. One or more from nodes are selected from the from XML document to compare to one or more to nodes from the to XML document. The comparison employs a set of matching functions that may be selected based on the domain of the source documents. The matching functions may compare just the tags of XML elements, and/or their text contents and/or any of their relevant attributes. The matching may be exact or approximate. Each matching function computes a score which may be weighted. For each pair of from/to nodes, an overall match-score is computed based on the scores of the individual matching functions. If the match-score reaches a matching-threshold, the pair is determined to be a match and further matching is stopped. The techniques are extended for comparing multiple from documents to a to document.

Abstract: Disclosed herein is a framework for conducting legal research, writing, and collaboration tasks and accumulating legal knowledge. The framework can contain a body of legal documents. Users can select quotations from the documents, group one or more quotations in a Quote Bundle, and add annotations to the quotations within the Quote Bundles and/or add annotations directly to the Quote Bundles. The quotations, annotations, and Quote Bundles can be shared between users. Furthermore, the Quote Bundles can be integrated with a built-in word processing tool to facilitate the writing process. As a user creates a document, one or more Quote Bundles can be displayed. A user can select a quotation from a Quote Bundle, which can then be added to their document. When a quotation is added to a user created document, the proper citation information can also be added without further action by the user.
