Automatic Editing Using Probabilistic Word Substitution Models
First Claim
1. A method of transforming an input sequence of unstructured speech recognition text into output structured document text, the method comprising:
- providing a probabilistic word substitution model to establish association probabilities indicative of target structured document text correlating with source unstructured speech recognition text;
considering a set of candidate sequences of structured document text based on the word substitution model with respect to an input sequence of unstructured speech recognition text;
evaluating the likelihood of candidates corresponding to the input sequence of unstructured speech recognition text;
determining as an output a most likely sequence of structured document text.

Abstract
An input sequence of unstructured speech recognition text is transformed into output structured document text. A probabilistic word substitution model is provided which establishes association probabilities indicative of target structured document text correlating with source unstructured speech recognition text. The input sequence of unstructured speech recognition text is looked up in the word substitution model to determine likelihoods of the represented structured document text corresponding to the text in the input sequence. Then, a most likely sequence of structured document text is generated as an output.
