Characterizing Question Facets for Complex Answer Retrieval [article]

Sean MacAvaney, Andrew Yates, Arman Cohan, Luca Soldaini, Kai Hui, Nazli Goharian, Ophir Frieder
2018 arXiv   pre-print
Complex answer retrieval (CAR) is the process of retrieving answers to questions that have multifaceted or nuanced answers.  ...  In this work, we present two novel approaches for CAR based on the observation that question facets can vary in utility: from structural (facets that can apply to many similar topics, such as 'History'  ...  Complex Answer Retrieval (CAR) frames this problem as an information retrieval (IR) task [2] .  ...

A multi-level model of information seeking in the clinical domain

Peter W. Hung, Stephen B. Johnson, David R. Kaufman, Eneida A. Mendonça
2008 Journal of Biomedical Informatics  
Conclusion: The described multi-level model provides a framework for future research and the foundation for development of an automated information retrieval system that uses an intelligent search agent  ...  Objective: Clinicians often have difficulty translating information needs into effective search strategies to find appropriate answers.  ...  The purpose for searching a resource may be to answer a simple question in its entirety, or to answer part of a complex question that contains several concepts, each requiring a different resource.  ...

Search Engines Going beyond Keyword Search: A Survey

Mahmudur Rahman
2013 International Journal of Computer Applications  
General Terms: Search Engine, Information Retrieval Keywords: keyword based search, semantic web search, search engine, computational knowledge engine, question-answering system  ...  This paper tries to identify the major challenges for today's keyword search engines to adapt with the fast growth of web and support comprehensive user demands in quick time.  ...  Question-Answering (QA) system The goal of the QA process is to retrieve answers to questions rather than full documents or best-matching passages, as most information retrieval systems currently do.  ...

The semantics of place-related questions

Werner Kuhn, Ehsan Hamzei, Martin Tomko, Stephan Winter, Haonan Li
2021 Journal of Spatial Information Science  
For the case of questions about geographic places, we present a complementary approach, showing how to derive possible questions from an ontology of spatial information and a classification of place facets  ...  The trend to equip information systems with question-answering capabilities raises the design problem of deciding which questions a system should be able to answer.  ...  For this purpose, we review primarily studies in geographic information retrieval (GIR) and geographic question answering, the main areas investigating the application of place-based question answering  ...

Compositional question answering: A divide and conquer approach

Hyo-Jung Oh, Ki-Youn Sung, Myung-Gil Jang, Sung Hyon Myaeng
2011 Information Processing & Management  
This paper describes how questions can be characterized for question answering (QA) along different facets and focuses on questions that cannot be answered directly but can be divided into simpler ones  ...  The goal of the proposed QA method is to answer a composite question by dividing it into atomic ones, instead of developing an entirely new method tailored for the new question type.  ...  Three facets for question type determination To determine the types of questions, we first identified and used three facets that help characterizing questions and prescribing system functionality accordingly  ...
