  • Methods and apparatus for similarity text search based on conceptual indexing
    Patent number: 6542889
    Abstract: In one aspect of the invention, a method of performing a conceptual similarity search comprises the steps of: generating one or more conceptual word-chains from one or more documents to be used in the conceptual similarity search; building a conceptual index of documents with the one or more word-chains; and evaluating a similarity query using the conceptual index. The evaluating step preferably returns one or more of the closest documents resulting from the search; one or more matching word-chains in the one or more documents; and one or more matching topical words of the one or more documents.

  • Method for building space-splitting decision tree
    Publication number: 20030061213
    Abstract: A method is provided for data classification that achieves improved interpretability and accuracy while preserving the efficiency and scalability of univariate decision trees. To build a compact decision tree, the method searches for clusters in subspaces to enable multivariate splitting based on weighted distances to such a cluster. To classify an instance more accurately, the method performs a nearest neighbor (NN) search among the potential nearest leaf nodes of the instance. The similarity measure used in the NN search is based on Euclidean distances defined in different subspaces for different leaf nodes. Since instances are scored by their similarity to a certain class, this approach provides an effective means for target selection that is not supported well by conventional decision trees.

  • Method and apparatus for dynamic and flexible table summarization
    Patent number: 6523040
    Abstract: A method for performing table summarization. In a data network requests arrive at random from viewing devices (i.e., PC, PDA, laptop, etc.) to view objects which oftentimes contain large tables. The table summarization method compresses the rows/columns of the large tables in addition to the column formats to more easily display the table on the viewing device, which oftentimes has a limited display capability. A set of default rules is specified for determining how the table compression is to be performed. In addition to the default rules, a user may specify a user viewing preference to further modify the table display. The table summarization method is performed dynamically. That is, it is performed in real-time in response to a user request which typically is issued over a data network such as the Internet.

  • Methods and apparatus for performing dimensionality reduction in a supervised application domain
    Patent number: 6505207
    Abstract: A technique of the system for generating a reduced representation of input data, wherein the input data has a first set of feature variables and a class variable associated therewith, comprises the following steps. A second set of feature variables is determined from the first set of feature variables, wherein the second set of feature variables corresponds to mutually orthogonal vectors. Then, one or more of the feature variables associated with the second set of feature variables are selected based on a level of discrimination with respect to the class variable. The input data is then represented using the one or more selected feature variables.
