TAILIEUCHUNG - Báo cáo khoa học: "User Requirements Analysis for Meeting Information Retrieval Based on Query Elicitation"

We present a user requirements study for Question Answering on meeting records that assesses the difficulty of users questions in terms of what type of knowledge is required in order to provide the correct answer. We grounded our work on the empirical analysis of elicited user queries. We found that the majority of elicited queries (around 60%) pertain to argumentative processes and outcomes. | User Requirements Analysis for Meeting Information Retrieval Based on Query Elicitation Vincenzo Pallotta Department of Computer Science University of Fribourg Switzerland Violeta Seretan Language Technology Laboratory University of Geneva Switzerland seretan@ Marita Ailomaa Artificial Intelligence Laboratory Ecole Polytechnique Fédérale de Lausanne EPFL Switzerland Abstract We present a user requirements study for Question Answering on meeting records that assesses the difficulty of users questions in terms of what type of knowledge is required in order to provide the correct answer. We grounded our work on the empirical analysis of elicited user queries. We found that the majority of elicited queries around 60 pertain to argumentative processes and outcomes. Our analysis also suggests that standard keyword-based Information Retrieval can only deal successfully with less than 20 of the queries and that it must be complemented with other types of metadata and inference. 1 Introduction Meeting records constitute a particularly important and rich source of information. Meetings are a frequent and sustained activity in which multiparty dialogues take place that are goal-oriented and where participants perform a series of actions usually aimed at reaching a common goal they exchange information raise issues express opinions make suggestions propose solutions provide arguments pro or con negotiate alternatives and make decisions. As outcomes of the meeting agreements on future action items are reached tasks are assigned conflicts are solved etc. Meeting outcomes have a direct impact on the efficiency of organization and team performance and the stored and indexed meeting records serve as reference for further processing Post et al. 2004 . They can also be used in future meetings in 1008 order to facilitate the decision-making process by accessing relevant information from previous meetings Cremers et al.
