摘要： A method, system, and article are provided for evaluating regular expressions over large data collections. A general purpose index is built to handle complex regular expressions at the character level. Characters, character classes, and associated metadata are identified and stored in an index of a collection of documents. Given a regular expression, a query is generated based on the contents of the index. This query is executed over the index to identify a set of documents in the collection of documents over which the regular expression can be evaluated. Based upon the query execution, the identified set of documents is returned for evaluation by the regular expression responsive to execution of the query over the index.

摘要： A text annotation structured storage system stores text annotations with associated type information in a structured data store. The present system persists or stores annotations in a structured data store in an indexable and queryable format. Exemplary structured data stores comprise XML databases and relational databases. The system exploits type information in a type system to develop corresponding schemas in a structured data model. The system comprises techniques for mapping annotations to an XML data model and a relational data model. The system captures various features of the type system, such as complex types and inheritance, in the schema for the persistent store. In particular, the repository provides support for path navigation over the hierarchical type system starting at any type.

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.
