Method and apparatus for improving the transcription accuracy of speech recognition software
ActiveUS7805299B2Improve accuracyEasy to identifySpeech recognitionDigital dataSpeech identification
A virtual vocabulary database is provided for use with a with a particular user database as part of a speech recognition system. Vocabulary elements within the virtual database are imported from the user database and are tagged to include numerical data corresponding to the historical use of the vocabulary element within the user database. For each speech input, potential vocabulary element matches from the speech recognition system are provided to the virtual database software which creates virtual sub-vocabularies from the criteria according to predefined criteria templates. The software then applies vocabulary element weighting adjustments according to the virtual sub-vocabulary weightings and applies the adjustment to the default weighting provided by the speech recognition system. The modified weightings are returned with the associated vocabulary elements to the speech engine for selection of an appropriate match to the input speech.

System, method, and computer program product for creating a virtual database
ActiveUS20110004586A1Error detection/correctionDigital data processing detailsTransaction logRecovery phase
A virtual database is attached to a server database management system (“DBMS”) such that the DBMS believes it needs to recover the database to a last known point of consistency. In order to perform this recovery, the DBMS requests the transaction log file entries to be read from what it believes is the database's transaction log file. However, the requests are intercepted and translated (unbeknownst to the DBMS) instead into requests to read the transaction log portion of the backup file. The DBMS then uses the transaction log records to bring the database to a point of transactional consistency, unaware that the log records are actually being sourced from the transaction log portion of the backup file. All changes made to the data during the recovery phase and later during the execution of any TSQL statements which insert, update, or delete data are routed into a cache file. Accordingly, a “virtual” database is created and used by the server DBMS engine as if it were a real database.

A client programming model with abstraction hides from an underlying client application or application program interface (API) the details of where each element of data is located, and which copy of the data is resident on an available server and associated databases. The model wraps a database, such as a virtual database, and provides data-dependent and application-dependent routing, failover, and operational administration.

Systems, methods and devices for providing device authentication, mitigation and risk analysis in the internet and cloud
The present invention is a method to provide mechanisms and judgment to determine the ongoing veracity of “purported” devices (sometimes called spoofing) with such parameters as unique device ID, access history, paths taken and other environmental data (Device Authentication).This invention relies upon a previous invention “Reputation Database in the cloud and Internet”—the internet is comprised of collections of devices, data, applications and networks all dynamically exchanging information among users. We present a mechanism for real time observation, and putting or accessing those observations into a distributed virtual database for contextual evaluation and analysis of how the internet is being used or potentially subverted. This includes real time evaluation of DNS database changes, server logs, performance, path resolution, device logs, tip data and law enforcement data.This invention is particularly useful for helping detect and mitigate data compromises, networks, systems and other assets within the internet.

A system and method for providing a virtual map database, referred to herein as the ''Virtual Database System'' (VDB). The VDB allows integration of map data, often from various sources, in a consistent manner for supply to an end user, while simultaneously ensuring that the entity best able to support a particular data source retains control over the data. In accordance with an embodiment, the VDB environment enables third-party data providers to associate their third-party-files with a base map or file-of-reference, thereby allowing for the creation of dynamic relationships between digital map features and other third-party data providers. The integration may be performed in a dynamic or real-time fashion, receiving up-to-date information from the various sources, creating links, and composing virtual maps, as needed or on-demand. Since the information is linked between the map providers and the various third parties, whenever an item of information or a link between items is updated in either the file-of-reference or in one of the third-party files, that updated information can be propagated back to all of the third-parties for further use in their software applications.
