Embodiments of the present invention provide a method, system and computer program product for maintaining distributed state consistency in a distributed computing application. In an embodiment of the invention, a method for maintaining distributed state consistency in a distributed computing application can include registering a set of components of a distributed computing application, starting a transaction resulting in changes of state in different ones of the components in the registered set and determining in response to a conclusion of the transaction whether or not an inconsistency of state has arisen amongst the different components in the registered set in consequence of the changes of state in the different ones of the components in the registered set. If an inconsistency has arisen, each of the components in the registered set can be directed to rollback to a previously stored state. Otherwise a committal of state can be directed in each of the components in the registered set.

Managing data consistency between loosely coupled components in a distributed computing system

Methods and apparatus, including computer products, for generating a natural language expression in response to a query. A computer-implemented method of generating a natural language expression in response to a query, includes generating a text frame from the query, and processing the text frame in conjunction with a grammar and one or more logic configuration files applied recursively to the text frame to generate the natural language expression from the query, the logic configuration files including functions that can pass arguments.

Natural language expression in response to a query

A method of maintaining a collection of data includes extracting text from the collection of data, the text corresponding to keys and values, generating a feature lexicon from the extracted text, generating a language lexicon from the extracted text and generating configuration files corresponding to the extracted text.

Bootstrapping in information access systems

A method of database aliasing is provided. A method for aliasing a collection of data includes extracting names and associated terms from the collection of data, generating normalized text from the names and associated terms, parsing the normalized text in conjunction with a grammar to produce meaning fragments and mapping the meaning fragments to a collection of concepts.

Database aliasing in information access system

A method of accessing information from a collection of data includes receiving a query, generating an inverse index of the collection of data and generating results to the query in conjunction with the inverse index.

Information retrieval from a collection of data

A method of generating prose in response to a query includes generating a text frame from the query and processing the text frame in conjunction with grammar rules to produce a prose rendition of the query.

Prose feedback in information access system

A method of discarding results of a search of a collection of data includes parsing a query to produce fragments, searching the collection of data for matches to the fragments, determining a number of matches, placing the matches in a hierarchical tree data structure, determining an amount of space to display the matches, eliminating matches in the hierarchical tree data structure to fit within the amount of space and summarizing the eliminated matches.

Intelligent discard in information access system

A method of accessing information includes processing a query, searching a collection of data for a set of results matching the query, selectively reducing the set of results to generate a subset of results, outputting a prose rendition of the query and outputting the subset of results.

Information access method

A method of parsing ambiguous grammar includes pre-compiling the grammar into a binary format, parsing a query, outputting a graph by combining the parsed query and the binary format of the grammar and outputting a frame representation of potential parses in the graph.

Parsing ambiguous grammar

A method of accessing information from a collection of data includes receiving a query, augmenting the query with canonical non-terminal concepts, generating an inverse index of the collection of data, the inverse index including canonical non-terminal representations of the data and generating results to the augmented query in conjunction with the inverse index.
