Implicit Durations Calculation and Similarity Comparison in Question Answering Systems

摘要

Mechanisms for performing a duration-based operation are provided. At least one document is received having a plurality of associated dates and/or times and concepts associated with the dates and/or times. The at least one document does not explicitly specify a duration between the dates and/or times. Dates and/or times in the at least one document having similar associated concepts are correlated and, for the correlated dates and/or times, an implicit duration is calculated based on the dates and/or times. The concepts are associated with the implicit duration and a first document in the at least one document is annotated with an implicit duration annotation that specifies the implicit duration and the associated concepts. A duration based operation is then performed based on the implicit duration annotation.

主权项

1. A method, in a data processing system comprising a processor and a memory, for performing a duration-based operation, the method comprising:
receiving, by the data processing system, at least one document having a plurality of associated dates and/or times and concepts associated with the dates and/or times, wherein the at least one document does not explicitly specify a duration between the dates and/or times; correlating, by the data processing system, dates and/or times in the at least one document having similar associated concepts; calculating, by the data processing system, for the correlated dates and/or times, an implicit duration based on the dates and/or times; associating, by the data processing system, the associated concepts with the implicit duration; annotating, by the data processing system, a first document in the at least one document with an implicit duration annotation that specifies the implicit duration and the associated concepts; and performing, by the data processing system, the duration-based operation based on the implicit duration annotation.
