A real-time system incorporating speech recognition and linguistic processing for recognizing a spoken query by a user and distributed between client and server, is disclosed. The system accepts user's queries in the form of speech at the client where minimal processing extracts a sufficient number of acoustic speech vectors representing the utterance. These vectors are sent via a communications channel to the server where additional acoustic vectors are derived. Using Hidden Markov Models (HMMs), and appropriate grammars and dictionaries conditioned by the selections made by the user, the speech representing the user's query is fully decoded into text (or some other suitable form) at the server. This text corresponding to the user's query is then simultaneously sent to a natural language engine and a database processor where optimized SQL statements are constructed for a full-text search from a database for a recordset of several stored questions that best matches the user's query. Further processing in the natural language engine narrows the search to a single stored question. The answer corresponding to this single stored question is next retrieved from the file path and sent to the client in compressed form. At the client, the answer to the user's query is articulated to the user using a text-to-speech engine in his or her native natural language. The system requires no training and can operate in several natural languages.

Disclosed herein is a method and system for integrating an enterprise's structured and unstructured data to provide users and enterprise applications with efficient and intelligent access to that data. Queries can be directed toward both an enterprise's structured and unstructured data using standardized database query formats such as SQL commands. A coprocessor can be used to hardware-accelerate data processing tasks (such as full-text searching) on unstructured data as necessary to handle a query. Furthermore, traditional relational database techniques can be used to access structured data stored by a relational database to determine which portions of the enterprise's unstructured data should be delivered to the coprocessor for hardware-accelerated data processing.

A system and method for searching recorded speech is disclosed. The system and method comprises converting the recorded speech into text using a voice recognition system. As the speech is being converted, naturally occurring breaks in the languages will be used to take time indexes from the recording. The system and method includes creating a full text index of the recorded speech utilizing an information extender. The full text index contains a plurality of time stamps that point to the occurrence of words in the recorded speech. Finally, the text is searched by a full text search server that has linguistic search capabilities using the full text index. Finally, the searched text, the text index and the recorded speech are stored in the database. The recorded speech is searched by locating relevant phrases or words, and then mapping the time stamps associated with the relevant phrases words back to the recorded speech in the database.

A system and method for preparing and searching a user-personalized library of content includes preparing a general library comprised of images of pages of content and electronically-searchable text corresponding to the text in the page images, which is then personalized by receiving from the user a selection of the content to include in the user's personalized library. User selection of content for a personalized library may be accomplished manually or automatically as a result of user actions, such as user review or purchase of content. Preferably, full text searching of the content in the user's personalized library is enabled. Page images in the personalized library containing text that match the user's search terms are provided to the user for display. Highlighting of search terms in page images by a user device and access rules that act to limit the viewing of content are further provided.

Full text searching may be made available for resources stored in a database according to a database schema. A method for conducting a search on structured data using a text search engine includes the steps of: modeling a resource stored in a relational data store as a web page; providing a locator to the resource; and providing the resource in a consumable format to the text search engine. The method may include the additional steps of: receiving a search on the resource; converting the search into a converted query consumable by the search engine; and providing the converted query to the search engine.

A hierarchical distributed search mechanism is integrated into a distributed file system. Traditional file system APIs (create, open, close, read, write, link, rename, delete, . . . ) and the over-the-wire protocols employed to project these APIs into remote client sites (CIFS, NFS, DDS, Appletalk) are extended to enable the dynamic creation of temporary directories containing links to objects identified by search engines (executing at sites “close” to “their” data) as meeting the search criteria specified by the first parameter of a search function call. The search function, derived from the standard file system API function create, is added to the file system API.

A full-text search index system and method is generated by creating instances of a database index from an in-memory inverted list of keywords associated with a text identifier and the occurrences of the keyword in the text. Instances of the index are placed in a priority queue. A merge scheduling process determines when a merge should be initiated, selects instances of the index to be merged and selects a type of merge to perform.

The present invention relates to a storage system including a de-duplicate function and a full-text search function or the like, and reduces an amount of index information about full-test search to save storage resource. In this system, a storage apparatus includes a processing unit for de-duplicating a plurality of files having the same content regarding a file group of data inputted/outputted through a host apparatus. A full-text search processing server performs a full-text search processing to the file group and includes a processing unit for causing the full-text search processing to correspond to de-duplicate. An index information creation processing performed to a plurality of target files having the same content by the full-text search processing unit is inhibited according to a status of de-duplicate to the file group by the processing unit. Thereby, the amount of index information can be reduced.

A search method, a search system, and a natural language comprehension system are provided. The search system includes a structured database and a search engine. The structured database stores a plurality of records, each of which has a title field and a content field. The title field includes at least one sub-field, and each sub-field includes an indication field and a value field. The indication field stores indication data, the value field stores value data, and the content field stores detailed content data. The search engine conducts a full-text search to the records in the structured database according to a keyword derived from a user's request formation, and a search result is transmitted to a knowledge comprehension assistance module, so as to recognize the user's intention. After the user's intention is recognized, information associated with the recognized user's intention is transmitted back to the user.

Techniques are provided for managing the creation, storage, search and delivery of rich media optimized for e-commerce in a distributed information network, e.g., the Internet. In an illustrative embodiment, a content creation phase generates rich media content in a single multimedia file in the format of a HotMedia file for delivery to a Rich Media Build Engine (RMBE). Rich media content is extracted from the file using pluggable and modular extractors providing an input to a commerce-based search engine and a full-text search engine. The outputs of the search engine are combined as a search result from which a searchable database directory is created. The output is stored in a conventional database, e.g., DB2. A web client is coupled to the search system through a web server providing a search query to the rich media database and receiving an output from the search engine.
