Abstract
One embodiment of the present invention includes means determining a concept representation for a set of text documents based on partial order analysis and modifying this representation if it is determined to be unidentifiable. Furthermore, the embodiment includes means for labeling the representation, mapping documents to it to provide a corresponding document representation, generating a number of document signatures each of a different type, and performing several data processing applications each with a different one of the document signatures of differing types.

41. A method, comprising:
-
identifying a number of events; providing a visualization of the events with a computer system, the visualization including a number of visualization objects each representing a different one of the events; positioning each of the visualization objects along a first axis to indicate timing of each of the events relative to one another with a corresponding initiation time and a corresponding termination time of each of the events being represented by an initiation point and termination point of each of the visualization objects along the first axis; and dimensioning each of the visualization objects between the corresponding initiation point and the corresponding termination point along the first axis to indicate event duration and along a second axis to indicate relative strength of the different one of the events. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48)

49. A method, comprising:
-
providing a set of text documents; evaluating time variation of a number of terms included in the documents; generating a number of clusters corresponding to the documents with a computer system as a function of the terms; and identifying a number of events as a function of a time variation of the clusters. - View Dependent Claims (50, 51, 52, 53, 54)

55. A method, comprising:
-
providing a number of textual documents arranged relative to a period of time; identifying a feature with a time varying distribution among the documents; evaluating presence of the feature for each of several different segments of the time period; and detecting an event as a function of the one of the segments with a frequency of the feature greater than other of the segments and a quantity of the documents corresponding to the feature. - View Dependent Claims (56, 57, 58, 59, 60)
