Abstract: A computer readable medium stores executable instructions to deterministically construct a text question for application to a data source. The executable instructions include executable instructions supply a user with an initial text question. The user is allowed to alter a sentence component of the initial text question to form an altered sentence component. It is identified when the altered sentence component in combination with remaining sentence components creates a grammatically incorrect question. A grammatically correct text question including the altered sentence component is supplied in response to the executable instructions to identify. A data source query is constructed from the grammatically correct text question. The data source query is applied to a data source to produce data results. The data results are presented to the user.

Abstract: A computer readable medium storing executable instructions to deterministically construct a text question for application to a data source includes executable instructions to allow a user to specify a second language different than a first language used as organizational schema of a data source. Language rules are loaded for the second language. The language rules are used to translate an initial text question from the first language to the second language. A user is supplied with the initial text question in the second language. The user is allowed to alter a sentence component of the text question to form an altered sentence component. Executable instructions identify when the altered sentence component in combination with remaining sentence components creates an invalid question and supplies sentence components to insure selection of a valid question. A data source query is constructed from the initial text question and at least one altered sentence component.

Abstract: A method of deterministically constructing a text question for application to a data source includes supplying a user with an initial text question. The user is allowed to alter a sentence component of the text question to form an altered sentence component. When the altered sentence component in combination with remaining sentence components creates an invalid question, sentence components are supplied to insure the selection of a valid question. A data source query is constructed from the initial text question and at least one altered sentence component. The data source query is applied to a data source to produce data results. The data results are presented to the user.

Abstract: A computer readable medium includes executable instructions to associate text sentence components with metadata. The executable instructions specify a subject that has a definition corresponding to a metadata source. The executable instructions identify a behavior that has a definition corresponding to a metadata source. The behavior is associated with at least one subject. The behavior and at least one subject allow a user to create a text question convertible to a query to a data source associated with the metadata source.

Abstract: A computer readable medium includes executable instructions to construct a database query based on a comparator. Executable instructions accept a comparator forming a part of a text question. A value that defines a subject within a text question is received. A structured database query is built based upon the comparator and the subject of the text question.
