Abstract: A system, method and computer-readable storage devices are for processing natural language commands, such as commands to a robotic arm, using a Tag & Parse approach to semantic parsing. The system first assigns semantic tags to each word in a sentence and then parses the tag sequence into a semantic tree. The system can use statistical approach for tagging, parsing, and reference resolution. Each stage can produce multiple hypotheses, which are re-ranked using spatial validation. Then the system selects a most likely hypothesis after spatial validation, and generates or outputs a command. In the case of a robotic arm, the command is output in Robot Control Language (RCL).

Abstract: Methods, systems, devices, and media for creating a plan through multimodal search inputs are provided. A first search request comprises a first input received via a first input mode and a second input received via a different second input mode. The second input identifies a geographic area. First search results are displayed based on the first search request and corresponding to the geographic area. Each of the first search results is associated with a geographic location. A selection of one of the first search results is received and added to a plan. A second search request is received after the selection, and second search results are displayed in response to the second search request. The second search results are based on the second search request and correspond to the geographic location of the selected one of the first search results.

Abstract: Methods, systems, devices, and media for creating a plan through multimodal search inputs are provided. A multimodal virtual assistant receives a first search request which comprises a geographic area. First search results are displayed in response to the first search request being received. The first search results are based on the first search request and correspond to the geographic area. Each of the first search results is associated with a geographic location. The multimodal virtual assistant receives a selection of one of the first search results, and adds the selected one of the first search results to a plan. A second search request is received after the selection, and second search results are displayed in response to the second search request being received. The second search results are based on the second search request and correspond to the geographic location of the selected one of the first search results.
