Abstract: The present invention is directed towards systems and methods for querying a data repository using a flexible natural language interface, which comprises receiving an initiated user question at a graphical user interface and generating automatically one or more suggested completed questions in response to the receipt of the initiated user question. A selected completed question at the graphical user interface is received and subsequently parsed into a logic representation. The logic representation is translated into an executable query, which is executed against the data repository. One or more search results in response to the executed translated query and presented at the graphical user interface. The present invention further comprises generating one or more analytic results corresponding to the one or more search responsive to the translated query.

Abstract: A machine translation system which operates by analyzing a source text to deduce information about the usage and meaning of the words of a source language text as they occur in context. This information is passed to an equivalencing module, which determines a set of equivalent target language words from which may be constructed a target language text by a generation module. The generation module has internal structure, including a tree construction module and a constraint checking module. The two modules operate in parallel. The tree constructor builds legal target language structures from which the translated text may be extracted. The constraint checker ensures that each structure which is built will be part of a global structure that uses all the words which appear in the input to the generation module.
