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.

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.

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.

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.

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.

Abstract: An LED warning lamp comprises a base, multiple lighting assemblies, a junction and a cover. The base has a cone protruding from the base and having an opening formed in an apex of the cone. Each lighting assembly has a circuit board and multiple LEDs mounted on the circuit board. Each circuit board is mounted on the cone and has a top connector having multiple contacts being connected to the LEDs. The junction is mounted on the opening and has multiple edges corresponding to the circuit boards, multiple recessed connectors formed respectively in the edges and respectively engaging the top connectors, a circuit and multiple wires. The circuit has multiple contacts respectively connecting to corresponding contacts of the top connectors. The wires are connected to the circuit of the junction and are mounted in the cone through the opening. Therefore, wiring is simplified for lower cost and production time.

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.

Abstract: An outdoor lamp with a hidden switch has a housing, a lamp, a switch and a control lever. The housing has a circumferential wall having a lever slot and a lever bracket formed inside the housing. The lamp is mounted inside the housing. The switch is mounted inside the housing, is connected electrically to the lamp and has a control member. The control lever is mounted pivotally on the lever bracket and has a proximal end extending to and abutting the control member of the switch and a distal end extending out of the lever slot to be wiggled by a user to switch on/off the lamp. The switch is hidden inside the housing to be protected from being wetted by rainwater and to avoid rust or a short circuit problem.
