METHODS AND APPARATUS TO CLASSIFY TEXT COMMUNICATIONS
First Claim
1. A method to classify text communications, the method comprising:
- determining a first score indicating a likelihood that a text belongs to a first classification mode by combining a first sentence score and a second sentence score retrieved from an index, the first sentence score indicating a probability that a first sentence in the text belongs to the first classification mode, the second sentence score indicating that a second sentence following the first sentence belongs to the first classification mode;
determining a second score indicating a likelihood that the text belongs to a second classification mode;
comparing the first score to the second score;
classifying the text as the first classification mode when the first score is greater than the second score; and
determining a confidence level that the text belongs to the first classification mode by dividing the first score by the second score.

Abstract
Methods and apparatus to classify text communications are disclosed. An example method includes determining a first score indicating a likelihood that a text belongs to a first classification mode by combining a first sentence score and a second sentence score retrieved from an index, the first sentence score indicating a probability that a first sentence in the text belongs to the first classification mode, the second sentence score indicating that a second sentence following the first sentence belongs to the first classification mode, determining a second score indicating a likelihood that the text belongs to a second classification mode, comparing the first score to the second score, classifying the text as the first classification mode when the first score is greater than the second score, and determining a confidence level that the text belongs to the first classification mode by dividing the first score by the second score.

9. A tangible computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
-
determine a first score indicating a likelihood that a text belongs to a first classification mode by combining a first sentence score and a second sentence score retrieved from an index, the first sentence score indicating a probability that a first sentence in the text belongs to the first classification mode, the second sentence score indicating that a second sentence following the first sentence belongs to the first classification mode; determine a second score indicating a likelihood that the text belongs to a second classification mode; compare the first score to the second score; classify the text as the first classification mode when the first score is greater than the second score; and determine a confidence level that the text belongs to the first classification mode by dividing the first score by the second score. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus to classify text communications, the apparatus comprising:
-
a statistics generator to determine a first score indicating a likelihood that a text belongs to a first classification mode by combining a first sentence score and a second sentence score retrieved from an index, the first sentence score indicating a probability that a first sentence in the text belongs to the first classification mode, the second sentence score indicating that a second sentence following the first sentence belongs to the first classification mode, and to determine a second score indicating a likelihood that the text belongs to a second classification mode; a search engine to compare the first score to the second score, classify the text as the first classification mode when the first score is greater than the second score, and determine a confidence level that the text belongs to the first classification mode by dividing the first score by the second score. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
