Abstract
A method for spatializing text content for enhanced visual browsing and analysis. The invention is applied to large text document corpora such as digital libraries, regulations and procedures, archived reports, and the like. The text content from these sources may be transformed to a spatial representation that preserves informational characteristics from the documents. The three-dimensional representation may then be visually browsed and analyzed in ways that avoid language processing and that reduce the analysts' effort.
Claims23
A method for presenting information by relative relationships of content and context of a plurality of documents, wherein the relative relationships are presented in a three-dimensional landscape with the relative size and height of a peak in the landscape representing the relative significance of a relationship of a topic attribute and each one of the documents, comprising the steps of:
- (a) representing each document as a high dimensional vector;
- (b) producing a partition set on the plurality of documents, said partition set resulting in a cluster centroid for each of the documents;
- and
- (c) projecting each said high dimensional vector and at least one said cluster centroid into a 2-dimensional representation.
A method for representing human comprehensible information in a low-dimensionality space based on a high dimensionality analysis thereof, the information comprising sets of semantic information, comprising the steps of:
- (a) representing the sets of semantic information as a vector in a high-dimensional information space;
- (b) segmenting the information space into a plurality or bounded continuous sub-spaces, each having a centroid;
- (c) projecting the segmented bounded continuous subspaces of the high-dimensional information space onto a low dimensional space, in a manner sensitive to a relation of each set of semantic information to each centroid.
A computer readable medium storing program instructions for programming a general purpose computer to perform a method for representing human comprehensible information in a low-dimensionality space based on a high dimensionality analysis thereof, the information comprising sets of semantic information, comprising the steps of:
- (a) representing the sets of semantic information as a vector in a high-dimensional information space;
- (b) segmenting the information space into a plurality of bounded continuous sub-spaces, each having a centroid;
- (c) projecting the segmented bounded continuous subspaces of the high-dimensional information space onto a low dimensional space, wherein said projection is sensitive to a relation of each set of semantic information to each centroid.
