چکیده

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 any point in time. In order to improve performance with such an open dialog strategy, we make use of implicit confirmation using the callers wording (when possible), and change to a more constrained dialog level when the dialog is not going well. Le système ARISE du LIMSI est un serveur téléphonique d’informations sur les trains grandes lignes en France. Il fournit les horaires, les prix et réservations simulés, les réductions ainsi que les services. Notre but est d’obtenir des taux de succès de dialogue élevés avec une interaction très ouverte, offrant à l’utilisateur la possibilité de poser des questions ou de donner des informations à n’importe quel moment. Afin d’améliorer les performances avec une telle stratégie, nous avons utilisé la confirmation implicite en fonction des formulations des utilisateurs ainsi qu’un dialogue plus contraint lorsque l’interaction se passe mal. Das vom LIMSI entwickelte ARISE System erlaubt den vokalen Zugriff auf Zugreiseinformationen. Neben Fahrplanauskünften zwischen den wichtigsten französischen Intercity-Verbindungen simulierte das System Zugfahrpreise, Ermä sigungen und anderen Serviceleistungen. Unser Ziel ist es, hohe Erfolgsraten im Mensch-Maschine Dialog zu erhalten. Erreicht werden soll dieses Ziel aber unter Benutzung einer sehr offenen Dialogstrategie, bei der der Benutzer zu jedem Zeitpunkt dem System Fragen stellen oder Informationen liefern kann. Um die Erfolgsraten mit solch einer offenen Dialogstrategie zu verbessern, benutzen wir die Technik oler impliziten Konfirmation, bei der (wenn möglich) die Formulierungen des Benutzers wiederverwendet werden. Sollte der Dialog schlecht verlaufen, so wechseln wir zu einem begrenzteren Dialog-Niveau.

LIMSI: Translations as Source of Indirect Supervision for Multilingual All-Words Sense Disambiguation and Entity Linking

We present the LIMSI submission to the Multilingual Word Sense Disambiguation and Entity Linking task of SemEval-2015. The system exploits the parallelism of the multilingual test data and uses translations as source of indirect supervision for sense selection. The LIMSI system gets best results in English in all domains and shows that alignment information can successfully guide disambiguation...

The 2004 BBN/LIMSI 20xRT English conversational telephone speech recognition system

In this paper we describe the English Conversational Telephone Speech (CTS) recognition system jointly developed by BBN and LIMSI under the DARPA EARS program for the 2004 evaluation conducted by NIST. The 2004 BBN/LIMSI system achieved a word error rate (WER) of 13.5% at 18.3xRT (realtime as measured on Pentium 4 Xeon 3.4 GHz Processor) on the EARS progress test set. This translates into a 22....

The LIMSI SDR System for TREC-9

In this paper we describe the LIMSI Spoken Document Retrieval system used in the TREC-9 evaluation. This system combines an adapted version of the LIMSI 1999 Hub-4E transcription system for speech recognition with text-based IR methods. Compared with the LIMSI TREC-8 system, this year’s system is able to index the audio data without knowledge of the story boundaries using a double windowing app...

The LIMSI 1997 Hub-4E Transcription System

In this paper we report on the LIMSI system used in the Nov’97 Hub-4E benchmark test on transcription of American English broadcast news shows. There are two main differences from the LIMSI system developed for the Nov’96 evaluation. The first concerns the preprocessing stages for partitioning the data, and the second concerns a reduction in the number of acoustic model sets used to deal with t...
