Abstract:
1. A method performed by a computer for using a classifier to find text data having a specific format, the method comprising the steps of: training the classifier to identify the specific format using data stored in a training corpus, wherein training comprises identifying positive and negative instances of the specific format within components of the training corpus; applying the trained classifier to a text corpus to identify components of the text corpus having a feature which corresponds to a characteristic of the specific format; identifying a subset of the identified components of the text corpus with an above-threshold probability of having a feature which corresponds to the characteristic of the specific format; gathering additional text data based on the identified subset of components of the text corpus; applying the trained classifier to the additional text data to identify components of the additional text data having the feature which corresponds to a characteristic of the specified format; generating by a computer rules from the identified subset of components of the text corpus and the identified components of the additional text data specifying the format of the identified subset of components of the text corpus and the identified components of the additional text data, wherein the rules correspond to the feature of the identified subset of components of the text corpus and the identified components of the additional text data; and storing the generated rules in a computer storage medium.
