  • Patent number: 11270153
    Abstract: The disclosed invention provides system and method for whole word conversion of text in an image. The system and method may convert the text in the image into Unicode strings. The system and method utilizes comparable features of word segments that are extracted from the text in the image. The comparable features of the word segments are created by mirroring comparable features of word templates stored in a conversion database. Word templates in the database are filtered by comparing the comparable features of the word segments with comparable features of the word templates in the database. The word segments are correlated to matching word candidates. Word confusion networks are constructed with the matching word candidates, and the word confusion networks are evaluated to output matching words for the word segments. This system and method reduce the search space in the database improving search efficiency.

  • Publication number: 20020138663
    Abstract: Disclosed is a method and apparatus in which one or more data streams are sent to a computer and the data streams are sorted using a rule base into streams representative of events. The incoming data streams can be sent by hunter agents which search for specified types of data and forward the data to the computer. The incoming data stream can also be sent by a gatherer agent. The incoming data stream can also be incoming message traffic such as e-mail and other types of message traffic data. The incoming message traffic data is then sorted into event streams and can be displayed as event streams on a time line. Actions can be taken based upon specified events. Thus, events from disjointed sources can be sorted and displayed in a unified manner in which a user can readily and quickly know which events have occurred for a particular issue, such as a forest fire, hospital patient, etc.
