    1. Machine translation system utilizing bilingual equivalence statements

      A machine translation system which operates by analyzing a source text to deduce information about the usage and meaning of the words of a source language text as they occur in context. This information is passed to an equivalencing module, which determines a set of equivalent target language words from which may be constructed a target language text by a generation module. The generation module has internal structure, including a tree construction module and a constraint checking module. The two modules operate in parallel. The tree constructor builds legal target language structures from which the translated text may be extracted ...

    5. Automatic method of generating thematic summaries

      A technique for automatically generating thematic summaries for machine readable representations of documents. The technique begins with determining the number of thematic terms to be used based upon the number of thematic sentence to be extracted. To insure some commonality of theme between extracted sentences, the number of thematic terms used should be less than the number of thematic sentences to be extracted. Having determined the appropriate number of thematic terms, next the method identifies the thematic terms within the document. Afterward, each sentence of the document is scored based upon the number of thematic terms contained within the sentence ...

    19. Archiving and retrieving multimedia objects using structured indexes

      To archive information, a phrase or sentence describing the information, typically expressed in a natural language and conforming to the rules of a grammar (like a natural language grammar) is used to create a structured index which also conforms to the natural language grammar. The structured index has structure because the words in the index have a function and a relationship among each other as determined by the grammar. The index is combined with a location pointer of information to be cataloged, preferably multimedia information, to form a matched pair, i.e., a structured index and a segment (or a ...

    23. System and method of context vector generation and retrieval

      A system and method for generating context vectors for use in storage and retrieval of documents and other information items. Context vectors represent conceptual relationships among information items by quantitative means. A neural network operates on a training corpus of records to develop relationship-based context vectors based on word proximity and co-importance using a technique of "windowed co-occurrence". Relationships among context vectors are deterministic, so that a context vector set has one logical solution, although it may have a plurality of physical solutions. No human knowledge, thesaurus, synonym list, knowledge base, or conceptual hierarchy, is required. Summary vectors of records ...

    24. Protection of an electronically stored image in a first color space by the alteration of a digital component in a second color space

      Digitized images are associated with English language captions and other data, collectively known as the metadata associated with the images. A natural language processing database removes ambiguities from the metadata, and the images and the metadata are stored in databases. A user formulates a search query, and natural language processing is used to determine matches between the query and the stored metadata. Images corresponding to the matches are then viewed, and desired images are selected for licensing. The license terms for selected images are displayed, and a subset of the selected images are ordered as desired by the user.
