Abstract: Technical solutions are described herein for position estimation of permanent magnet synchronous machines through vibration induced saliency. An example permanent magnet synchronous machine (PMSM) includes a motor control system to provide input command to the motor to cause a position of the motor to change. The PMSM further includes a motor position estimation module configured to estimate the position of the motor. The estimation includes measuring a current Iabc across the motor. The estimation further includes extracting a filtered current Iabc_inj at a predetermined frequency from the current Iabc. The estimation further includes estimating the position of the motor based on the filtered current Iabc_inj.

Abstract: An approach is provided that receives a question at a question answering (QA) system. The question includes a number of words. The approach operates by calculating weights that correspond to search terms included in the plurality of words. The search terms include the plurality of words and may include terms that are one or more sequences of adjacent words included in the question. Based on the calculated weights and the words in the question, the approach generates a query that is used to search a corpus that is managed by the QA system with the search resulting in one or more search results.

Abstract: A computer-implemented method generates a temporal candidate answer to a question. One or more processors tag terms found in multiple text passages with a part of speech (POS) tag, and then parse POS tagged terms found in the multiple text passages to generate passage triples for multiple parts of each of the multiple text passages. The processor(s) filter each sub-passage from the multiple text passages, which removes passages from each of the multiple text passages that are not associated with said each sub-passage. The processor(s) temporally align each sub-passage triple with a particular time range, and then extract text within each sub-passage from the multiple text passages to create a temporal candidate answer identified by the associated sub-passage triple. Upon receipt of a question related to a sub-passage that is related to the particular time range, the processor(s) return the temporal candidate answer that is temporally aligned with the question.

Abstract: A computer-implemented method generates a candidate answer triple for use in retrieving information used to answer a question. One or more processors parse a question to identify a lexical answer type for the question, a question action for the question, and a question timestamp for the question to make up a question triple. One or more processors retrieve multiple candidate passages for answering the question, and parse each of the multiple candidate passages to identify a candidate entity, a candidate action, and a candidate timestamp from each of the multiple candidate passages to generate a candidate answer triple. One or more processors compare the question triple to the candidate answer triple and establish a match score for each candidate answer triple, which is used in retrieving information used to answer the question.
