  • Patent number: 9009074
    Abstract: Systems and methods are provided for generating and publishing electronic spare parts catalogs that support electronic business processes for managing and selling spare parts for complex machines and systems, such as gas turbines. Automated systems and methods for generating electronic catalogs of spare parts employ an extensible, template-based framework to extract and integrate catalog content (static and/or real-time spare parts data) from various backend business information systems and data sources.

  • Patent number: 7370061
    Abstract: A technique for optimizing the archival and management of data stored as XML documents is capable of handling mixed data including highly structured data and unstructured data. The technique maps the structured data to a relational database while storing the unstructured data in its native XML format. The data is updated using a rules database that maps updating rules against attributes and classes of elements within the documents. A document checking/validation engine performs the updates based on rule verification. A search engine searches the documents using both a path index table and a weighted content index.

  • Patent number: 7120642
    Abstract: A Product Document Constraint Specification Language (PDCSL) is provided for a document author to represent various types of documentation guidelines that must be enforced within documents or across different documents. A Document Constraint Analyzer (DCA) takes as input a set of document files together with a document constraint specification file, extracts and examines the contents, attributes, and relationships associated with the document objects, and evaluates the logical expressions specified in the document constraints. If a document constraint is not satisfied, an action can be taken to correct the documents or provide an explanation to the document author.

  • Patent number: 7013309
    Abstract: A method for extracting Anchorable Information Units (AIUs), from a Portable Document Format (PDF) file, which may either be created using either an editor or by scanning in documents. The method includes parsing the portable document format document into textual portions and non-text portions, and extracting structure from the textual portions and the non-text portions. The method further includes determining text within textual portions, and text the non-text portions, and hyperlinking a plurality of keywords within the textual portions and non-text portions to a related document.

  • Publication number: 20040268238
    Abstract: Systems and methods for document processing using XML-based template server pages. An XML-based Process Flow Description Language (PFDL) is employed to describe a processing model for specifying a processing sequence of XML-based template sever pages, which supports development of Web-based applications and services. A processing model for processing XML-based template server pages is preferably based on an extensible, XML-based, pipeline processing model that specifies a collection of template processors (XML applications) that are executed in a specified sequence for processing XML-based templates, and which can interpret processor-specific XML elements within the templates.

  • Publication number: 20040268230
    Abstract: Systems, methods and applications for updating or otherwise modifying documents, post delivery, by distributing difference documents over a network for document delivery. The difference documents include content difference specifications and/or presentation difference specifications, as described using a formal delta (or difference) description specification. Preferably, the difference specifications comprise a sequence of labeled and conditional XML content and presentation difference descriptions that enable a presentation document to be directly update without having to actually modify the source document(s) associated with the presentation document.

  • Publication number: 20040267550
    Abstract: An automated method for authoring product catalogs includes setting up a catalog database for storing and providing data for use in the authoring of the product catalogs and authoring a product content. This includes updating a product structure, including storing new data, selecting views for a product wherein the views comprise a respective hierarchical structure of objects of various types, associating the new data with respective selected views, entering product data for the objects of various types, and updating and organizing the objects, in each case, based on the respective hierarchical structure such that the product content for all required views is stored in the catalog database.

  • Publication number: 20040267720
    Abstract: A query system for structured multimedia content retrieval comprises a query language based on logic formalism for content retrieval. The language includes query constructs and formalisms for specifying different aspects of XML documents and the constructs and formalisms are particularly adapted for spatial, temporal and visual datatypes. Certain critical specification issues in MPEG-7 XML queries are identified. An XML query language with multimedia query constructs is described which is based on a logic formalism, called path predicate calculus. In this path predicate calculus, the atomic logic formulas are element predicates rather than relation predicates in relational calculus. In this path calculus query language, queries in this calculus are equivalent to finding all proofs to existential closure of logical assertions in the form of path predicates that the tree document elements must satisfy.

  • Publication number: 20040194032
    Abstract: A product document profiling system and method for automatically generating product-specific documents from a master document. A product document profiling system comprises a document variant calculator module and a document selector module. The document variant calculator module processes product specifications for specific products and component definitions for components of a master document, and generates document variants for the specific products. Each document variant comprises a set of component identifiers that identify components of the master document which are associated with a given specific product. The document selector module processes the master document and the document variants to automatically generate a plurality of document instances of the master document. Each document instance comprises a unique document profile for a specific product.

  • Publication number: 20030101414
    Abstract: There is provided a formed-based document generator for dynamically generating two-layer form documents from two-layer form specifications. A background document generator generates a background document layer having a static data format, from background media and from two-layer form specifications that comprise high-level XML-based specifications. A foreground form overlayer generates a foreground document layer having a dynamic data collecting capability, from the two-layer form specifications. A mixing buffer mixes the background document layer and the foreground document layer to generate a two-layer form document. A data collector collects static and dynamic data for inclusion in the two-layer form document.

  • Patent number: 5995659
    Abstract: A method for recognizing text in graphical drawings includes creating a binarized representation of a drawing to form an electronic image of pixels. The image is discriminated between text regions and lines in the image by grouping pixels into blocks and comparing blocks with a predetermined format to identify text regions. The lines that remain in the text regions are removed to create text only regions. The text is recognized in the text only regions.
