Towards End-to-End Reinforcement Learning of Dialogue Agents for Information Access [PDF]
Annual Meeting of the Association for Computational Linguistics, 2016 This paper proposes KB-InfoBot - a multi-turn dialogue agent which helps users search Knowledge Bases (KBs) without composing complicated queries. Such goal-oriented dialogue agents typically need to interact with an external database to access real ...

Accessibility in Information Retrieval [PDF]
, 2008 This paper introduces the concept of accessibility from the field of transportation planning and adopts it within the context of Information Retrieval (IR). An analogy is drawn between the fields, which motivates the development of document accessibility measures for IR systems. Considering the accessibility of documents within a collection given an IR
