The aim of the MEDIA-EVALDA project is to evaluate the understanding capabilities of dialog systems. This paper presents the MEDIA protocol for speech understanding evaluation and describes the results of the June 2005 literal evaluation campaign. Five systems, both symbolic or corpus-based participated to the evaluation which is based on a common semantic(More)
The LIMSI ARISE system provides vocal access by telephone to rail travel information for main French intercity connections, including timetables, simulated fares and reservations, reductions and services. Our goal is to obtain high dialog success rates with a very open interaction, where the user is free to ask any question or to provide any information at(More)
The evaluation of named entity recognition (NER) methods is an active field of research. This includes the recognition of named entities in speech transcripts. Evaluating NER systems on automatic speech recognition (ASR) output whereas human reference annotation was prepared on clean manual transcripts raises difficult alignment issues. These issues are(More)
One central goal of the AMITIÉS multilingual humancomputer dialogue project is to create a dialogue management system capable of engaging the user in human-like conversation in a specific domain. To that end, we have developed new methods for the manual annotation of spoken dialogue transcriptions from European financial call centers. We have modified the(More)
The project RITEL aims at integrating a spoken language dialog system and an open-domain question answering system to allow a human to ask general questions (“Who is currently presiding the Senate?”) and refine the search interactively. As this point in time the RITEL platform is being used to collect a human-computer dialog corpus. The user can receive(More)
Dialog management is of particular importance in telephone-based services. In this paper we describe our recent activities in dialog management and natural language generation in the LIMSI RAILTEL system for access to rail travel information. The aim of LEMLAP project RAILTEL was to assess the capabilities of spoken language technology for interactive(More)
In the context of the LE-3 ARISE project we have been developing a dialog system for vocal access to rail travel information. The system provides schedule information for the main French intercity connections, as well as, simulated fares and reservations, reductions and services. Our goal is to obtain high dialog success rates with a very open dialog(More)
