Currently there are no dialog systems that enable purely voice-based access to the unstructured information on websites such as Wikipedia. Such systems could be revolutionary for non-literate users in the developing world. To investigate interface issues in such a system, we developed VoicePedia, a telephone-based dialog system for searching and browsing Wikipedia. In this paper, we present the system, as well as a user study comparing the use of VoicePedia to SmartPedia, a Smartphone GUI-based alternative. Keyword entry through the voice interface was significantly faster, while search result navigation, and page browsing were significantly slower. Although users preferred the GUI-based interface, task success rates between both systems were comparable – a promising result for regions where Smartphones and data plans are not viable. Index Terms: dialog system, information access 1.

Abstract: Recent advances in massive information storage and growth of internet have led to increased necessity of tools such as search engines and QA systems to get meaningful answers from the vast amount of information. The complex questions appearing in real-life generally require multiple techniques or sub-division of question at various levels. Several practical systems have been developed to explore this. This paper reviews state-of-art QA systems which provide enhanced and versatile functionality at various levels in their architecture and then makes the following contributions: 1 it provides useful overview of research trends and recent developments in the area of QA 2 the paper introduces and defines basic design parameters for any QA system 3 it resolves semantic heterogeneity by clarifying the meaning and context in which different terms are used by different researchers 4 it classifies the existing QA systems in broad groups, based on the point at which versatility (multiplicity) is introduced/handled in the system 5 by developing a unified view of existing frontiers of QA systems, it provides clear directions for future research and development in the area.

In this paper we describe the web and mobile-phone interfaces to our multilanguage factoid question answering (QA) system together with a prototype speech interface to our English-language QA system. Using a statistical, data-driven approach to factoid question answering has allowed us to develop QA systems in five languages in a matter of months. In the web-based system, which is accessible at
