  • Methods, systems, and computer program products for editing using an interface
    Patent number: 8312379
    Abstract: Methods, computer program products, and systems for editing using an interface for selecting and presenting editing tools are described. An input document is received for editing. A strategy for editing the document is identified. Editing tools are selected to edit the document, and the selected editing tools are presented.

  • Associative memory processing method for natural language parsing and pattern recognition
    Patent number: 5619718
    Abstract: An associative memory processor architecture is disclosed for the fast and efficient execution of parsing algorithms for natural language processing and pattern recognition applications. The architecture consists of an associative memory unit for the storage of parsing state representations, a random access memory unit for the storage of the grammatical rules and other tables according to which the parsing is done, a finite state parsing control unit which embodies the chosen parsing algorithm, and a communications unit for communication with a host processor or external interface. The use of associative memory for the storage of parsing state representations allows the architecture to reduce the algorithmic time complexity of parsing algorithms both with respect to grammar size and input string length, when compared to standard software implementations on general purpose computers.
