Ralph M. Weischedel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8527522
    Abstract: The invention relates to cross-document entity co-reference systems in which naturally occurring entity mentions in a document corpus are analyzed and transformed into name clusters that represent global entities. In a first aspect of the invention, a name variation module analyzes naturally occurring names of entities extracted from the document corpus and provides an initial set of equivalent names that could refer to the same real world entity. In a second aspect of the invention, a disambiguation module takes the initial set of equivalent names and uses an agglomerative clustering algorithm to disambiguate the potentially co-referent named entities.

  • Patent number: 8249856
    Abstract: A method for computer-assisted translation from a source language to a target language makes use of number of rules. Each rule forms an association between a representation of a sequence of source language tokens with a corresponding tree-based structure in the target language. The tree-based structure for each of at least some of the rules represents one or more asymmetrical relations within a number of target tokens associated with the tree-based structure and provides an association of the target tokens with the sequence of source language tokens of the rule. An input sequence of source tokens is decoded according to the rules to generate a representation of one or more output sequences of target language tokens. Decoding includes, for each of at least some sub-sequences of the input sequence of source tokens, determining a tree-based structure associated with the sub-sequence according a match to one of the plurality of rules.

  • Patent number: 8131536
    Abstract: The invention relates to systems and methods for automatically translating documents from a first language to a second language. To carry out the translation of a document, elements of information are extracted from the document and are translated using one or more specialized translation processes. The remainder of the document is separately translated by a statistical translation process. The translated elements of information and the translated remainder are then merged into a final translated document.
