QA-It: Classifying Non-Referential It for Question Answer Pairs

This paper introduces a new corpus, QA-It, for the classification of non-referential it. Our dataset is unique in a sense that it is annotated on question answer pairs collected from multiple genres, useful for developing advanced QA systems. Our annotation scheme makes clear distinctions between 4 types of it, providing guidelines for many erroneous cases. Several statistical models are built ...

Final Answer: Ghrelin Can Suppress Insulin Secretion in Humans, but Is It Clinically Relevant?

Ghrelin is a 28–amino acid peptide initially isolated from rat and human stomachs as an endogenous ligand for the growth hormone secretagogue receptor type 1a (GHS-R1a) (1) using an intracellular calcium influx assay on a stable cell expressing rat GHS-R. At the time of its discovery in 1999, ghrelin was known to increase growth hormone release from the pituitary gland by binding to GHS-R1a, an...

Multiagent learning is not the answer. It is the question

The article by Shoham, Powers, and Grenager called “If multi-agent learning is the answer, what is the question?” does a great job of laying out the current state of the art and open issues at the intersection of game theory and artificial intelligence (AI). However, from the AI perspective, the term “multiagent learning” applies more broadly than can be usefully framed in game theoretic terms....

It Takes Three to Tango: Triangulation Approach to Answer Ranking in Community Question Answering

We address the problem of answering new questions in community forums, by selecting suitable answers to already asked questions. We approach the task as an answer ranking problem, adopting a pairwise neural network architecture that selects which of two competing answers is better. We focus on the utility of the three types of similarities occurring in the triangle formed by the original questi...
