System for information storage, retrieval and voice based content search and methods thereof

A system for information retrieval and voice based content search, the system comprising:

• a remote communications device configured to communicate through a telecommunication network;
• a base station selectively in communication with the remote communications device, the base station having:
• an information retrieval system comprising a server storage configured to store contents;
• a content extractor configured to extract contents from the server storage;
• an adaptive indexer configured to adaptively index contents extracted by the content extractor;
• a core indexer configured to collect textual information from the extracted contents;
• an index configurator configured to configure the adaptive indexer using the extracted contents;
• a content cataloguer configured to catalogue the indexed contents;
• an index re-shuffler configured to periodically reshuffle the indexed contents;
• a local memory configured to store contents, the memory positioned proximally to the storage adapter;
• a storage adapter configured to provide access to the contents stored in the local memory;
• a dynamic grammar generator configured to generate speech recognition grammar;
• a voice information retrieval interface operatively interfacing with the dynamic grammar generator;
• a speech recognition platform interfacing with the voice information retrieval interface;
• a markup language generator/parser configured to create and interpret contents using voice mark up languages, and wherein the base station further comprising a search engine coupled to the voice information retrieval interface, the adaptive indexer operatively connected to the content extractor, the content extractor configured to perform indexing of contents extracted from the remote server storage;
• the core indexer extracts textual matter from the contents, the contents being catalogued by a content cataloguer, indexed contents being stored in the local memory, the storage adapter configured to provide access to the contents stored in the local memory, the dynamic grammar generator configured to generate speech recognition grammar, the markup language generator configured to wrap the grammar into a markup language document, the voice information retrieval interface configured to send the markup language document to the speech recognition platform, the speech recognition platform configured to use the document received from the information retrieval interface to recognizing the user input, the speech recognition platform returns the results thereof to the search engine, the search engine configured to perform search using the speech recognition results and the indexed contents and returns the results thereof as a markup language document to the speech recognition platform.

An adaptive indexing system configured to adapt indexing contents for use in an information retrieval system, the system comprising:

• an adaptive indexer configured to index contents;
• a core indexer configured to implement textual extraction from contents forwarded by the adaptive indexer;
• an index re-shuffler configured to at times reshuffle contents;
• an index configurator configured to index the contents received by the adaptive indexer employing a plurality of configuration parameters;
• an index cataloguer interfacing with the adaptive indexer configured to perform cataloguing of the contents and maintaining a per-user catalogue configured for a specific content type wherein the index cataloguer is configured to selectively load the indices upon receipt of a search request;
• a duplicate word remover configured to remove duplicate words from the indexed contents;
• a local memory configured to store contents, the memory positioned proximally to the storage adapter;
• a storage adapter configured to provide access to the contents stored in the local memory;
• an exclusion dictionary configured to exclude irrelevant words from the indexed contents;
• a dynamic grammar generator configured to generate speech recognition grammar and wherein the adaptive indexer coupled to the index configurator, the core indexer and the storage adaptor indexes the contents to define a user index and a common index, the grammar generator configured to process search requests to conduct searches using the user indexes and the common indexes and performs context sensitive selective loading of indices.
