摘要： A method, device, and computer program product are provided for regular expression learning is provided. An initial regular expression may be received from a user. The initial regular expression is executed over a database. Positive matches and negative matches are labeled. The initial regular expression and the labeled positive and negative matches are input in a transformation process. The transformation process may iteratively execute character class restrictions, quantifier restrictions, negative lookaheads on the initial regular expression to transform the initial regular expression into the pool of candidate regular expressions. The transformation process may execute, one at a time, the character class restrictions, quantifier restrictions, the negative lookaheads. A candidate regular expression is selected from the pool of candidate regular expressions, where the selected candidate regular expression has a best F-Measure out of the pool of candidate regular expressions.

摘要： A method of performing transactional web page searches is disclosed. The method includes examining a plurality of web pages, identifying transactional features within a set of the plurality of web pages, and classifying the set of web pages as transactional. The method proceeds with annotating and indexing the transactional web pages, and, in response to a user-designated transactional query, providing only the set of web pages that have been classified as transactional. The identifying transactional features comprises checking for the existence of positive patterns and verifying the absence of negative patterns with respect to a set of contents within each of the plurality of web pages and comprises identifying transactional actions to be performed and identifying transactional objects of the transactional actions to be performed. The annotating and indexing the transactional features comprises annotating and indexing transactional actions and transactional objects.
