A computer system has an interface to one or more databases, one or more base query objects, query objects, compound queries, annotator objects and graphical user interfaces (GUI's). The base query objects have one or more base query object methods, base variables, and base objects, the base query object methods being specific to the specific database and capable of querying the specific database. Each of the query objects derived from one of the base objects, and has a query type, one or more query object methods, query object variables, and query object objects. Each query object method is capable of querying a specific database to obtain a type result having the respective type. The compound query has one or more compound query methods, compound query variables, and compound query object objects. The operator objects, are derived from one of the base query objects that are used with the specific database. (GUI) has one or more query elements with one or more operators. The query elements, operators, and conditions are user selectable. Each query element, operates on the query object with the same type as the query element to create an instance of the query object with the query element. The compound query object instance uses the instances and the operator object instances to create an a query expression for the specific database. Therefore the input in the GUI is translated into a single compound query object.

Object oriented query model and process for complex heterogeneous database queries

An interactive computer system having a processor executing a target computer program, and having a speech recognizer for converting an utterance into a command signal for the target computer program. The target computer program has a series of active program states occurring over a series of time periods. At least a first active-state image is displayed for a first active state occurring during a first time period. At least one object displayed in the first active-state image is identified, and a list of one or more first active-state commands identifying functions which can be performed in the first active state of the target computer program is generated from the identified object. A first active-state vocabulary of acoustic command models for the first active state comprises the acoustic command models from a system vocabulary representing the first active-state commands. A speech recognizer measures the value of at least one feature of an utterance during each of a series of successive time intervals within the first time period to produce a series of feature signals. The measured feature signals are compared to each of the acoustic command models in the first active-state vocabulary to generate a match score for the utterance and each acoustic command model. The speech recognizer outputs a command signal corresponding to the command model from the first active-state vocabulary having the best match score.
