Interpreting Consumer Health Questions: The Role of Anaphora and Ellipsis.
While interest in biomedical question answering has been growing, research in consumer health question answering remains relatively sparse. In this paper, we focus on the task of consumer health question understanding. We present a rule-based methodology that relies on lexical and syntactic information as well as anaphora/ellipsis resolution to construct structured representations of questions (frames). Our results indicate the viability of our approach and demonstrate the important role played by anaphora and ellipsis in interpreting consumer health questions.
