- Zi Yang, Eric Nyberg. 2015. Leveraging Procedural Knowledge for Task Understanding : OAQA at TREC 2015 Tasks Track. Abstract: CMU OAQA team participated in the Task Understanding subtask in the Tasks track, and submitted three runs rsf, lsf, and lsfs for official evaluation. In our earlier work [1], we proposed to leverage procedural knowledge (e.g. wikiHow or eHow) for task-oriented search problems including query suggestion, which is similar to the goal of this Task Understanding task. Therefore, we reused the same system1, the wikiHow corpus2, and the pretrained model to generate key phrases for the 50 sample queries. Since our approach entirely relies on a procedural knowledge base, the freebaseID fields in the given input file were not used in our system, although ambiguity might become an issue in some cases. We intend to take the advantage of the TREC evaluation to test if our hypotheses that were stated in our earlier work still hold:
