  • Patent number: 10847175
    Abstract: In some natural language understanding (NLU) applications, results may not be tailored to the user's query. In an embodiment of the present invention, a method includes tagging elements of automated speech recognition (ASR) data based on an ontology stored in a memory. The method further includes indexing tagged elements to an entity of the ontology. The method further includes generating a logical form of the ASR data based on the tagged elements and the indexed entities. The method further includes mapping the logical form to a query to a respective corresponding database stored in the memory. The method further includes issuing the query to the respective corresponding databases. The method further includes presenting results of the query to the user via a display or a voice response system.

  • Patent number: 10769186
    Abstract: In an embodiment, a method includes determining, based on a received query and contextual information, candidate reasoners to respond to a received query to select a candidate reasoner. A reasoner or candidate reasoner is a module that translates information from a sensor, user settings, or other source, into additional or revised fields for a query. The method further includes generating, at each candidate reasoner determined, additional or revised query fields based on the contextual information and a rule of a rule database. The method further includes merging the additional query fields for each candidate reasoner based on a confidence score or other metric of each corresponding candidate reasoner. The confidence score can be based on applicability of the contextual information to the received query. The method further includes providing an enhanced query having the additional or revised query fields.

  • Patent number: 10631057
    Abstract: Presenting natural-language-understanding (NLU) results can include redundancies and awkward sentence structures. In an embodiment of the present invention, a method includes, responsive to receiving a result to a NLU query, loading a matching template of a plurality of templates stored in a memory. Each template has mask fields associated with at least one property. The method compares the properties of the mask fields of each of the templates to properties of the query and properties of the result, and selects the matching template. The method further completes the matching template by inserting fields of the result into corresponding mask fields of the matching template. The method may further suppress certain mask fields of the matching template to increase brevity and improve the naturalness of the response when appropriate based on the results of the NLU query. The method further presents the completed matching template to a user via a display.

  • Patent number: 8489639
    Abstract: An information source alignment system may include a tree generation module executed by a computer system to generate a source category hierarchy tree for a source class in a first information source and a target category hierarchy tree for a target class in a second information source. The source and target category hierarchy trees may be constructed from a class hierarchy of a knowledge source. A class-similarity determination module may compare the source and target category hierarchy trees. An alignment module may determine whether the source and target classes are aligned based on the comparison of the source and target category hierarchy trees.

  • Patent number: 7771092
    Abstract: An adjustable warning light housing has a base, two adjustable shields respectively and pivotally connected to two opposite inner surfaces of the base, two positioning assemblies respectively mounted between the base and the adjustable shields and an upper shield mounted on the outer surface of the base adjacent to the adjustable shields. A lighting assembly may be mounted inside the base to emit warning signals. The adjustable shields and the upper shield allow the warning light housing to fit different kinds of windshields of vehicles simply and easily. Warning signals being emitted by the lighting assembly cannot reflect into the vehicles so do not disturb a drivers of the vehicles for improved safety.

  • Publication number: 20080106430
    Abstract: A modular LED warning lamp has a base, a lamp module and a lamp shade. The lamp module is mounted on the base and has a positioning sleeve, multiple circuit panels and a circuit board. The positioning sleeve has multiple positioning sections formed and arranged circularly on an outer wall of the positioning sleeve. Each circuit panel is mounted individually on one of the positioning sections and has at least one LED. The circuit board is connected electrically to the LEDs. The circuit panels can be selectively mounted on some specific positioning sections to achieve a desired emitting angular range. Additionally, The circuit panels can be standardized to various types, which with different numbers of LEDs for use in the positioning sleeve. Such that, time and cost for developing a warning lamps with specific brightness and emitting angular range are reduced.

  • Publication number: 20070108719
    Abstract: An auxiliary balancing device for a retractable step assembly is mounted between two distal ends of two linkages of the retractable step assembly and includes two driving gears and an interaction gear assembly. The two driving gears are mounted to the two distal ends of the two linkages, respectively. The interaction gear assembly is mounted between and meshes with the two driving gears so that the two driving gears rotate synchronously. Thus, the step of the retractable step assembly can be kept balanced and horizontal when being lowered or raised.
