A Joint Model for Answer Sentence Ranking and Answer Extraction

Answer sentence ranking and answer extraction are two key challenges in question answering that have traditionally been treated in isolation, i.e., as independent tasks. In this article, we (1) explain how both tasks are related at their core by a common quantity, and (2) propose a simple and intuitive joint probabilistic model that addresses both via joint computation but task-specific applica...

Answer Credibility: A Language Modeling Approach to Answer Validation

Answer Validation is a topic of significant interest within the Question Answering community. In this paper, we propose the use of language modeling methodologies for Answer Validation, using corpus-based methods that do not require the use of external sources. Specifically, we propose a model for Answer Credibility which quantifies the reliability of a source document that contains a candidate...

CoMiC: Adapting a Short Answer Assessment System for Answer Selection

Open forum threads exhibit a great variability in the quality and quantity of the answers they attract, making it difficult to manually moderate and separate relevant from irrelevant content. The goal of SemEval 2015 Task 3 (Subtask A, English) is to build systems that automatically distinguish between relevant and irrelevant content in forum threads. We extend a short answer assessment system ...

Dually Structured Concepts in the Semantic Web: Answer Set Programming Approach

There is an ongoing discussion whether reasoning in the Semantic Web should be monotonic or not. It seems however that the problem concerns not only the reasoning over knowledge but knowledge itself, where apart from nondefeasible knowledge the prototypical knowledge can be distinguished. In the current paper we rely on the cognitive Dual Theory comprising the classical theory of definition wit...
