« Multimodal Corpora» Workshops at LREC Year Submis Accept Partici sions ed pants Sessions 2006 17 13 25 Meeting analysis (2), Metadata (1), Hand gesture (3), Conversation (3), HCI (3) 2004 15 10 40 Recommendations for tools & schemes (2), design & evaluation (4), Sign Lg (1), Coding schemes (4) 2002 ~15 15 40 Multimodal resources & annotation (2), gesture & speech (2), facial expressions (2), tools (4), fusion (2), infrastructure (2), evaluation (1) 2000 Metadata & large corpora 2

2006 Summary • Several types of settings / corpora required – Human-Computer Interaction: GUI, ECA, robot – Human-Human: TV, Cartoon, Meetings, Conversations, scenario based or not – Human modalities: hand gestures, audiovisual speech, head, gaze, interpersonal distance – Top-down vs. bottom-up approaches – Evaluation & validation of annotation – Duration of videos data, Nb of video taped people – Media : audio, image, sensors 3

2006 Summary • Research questions – – – – Capturing semantics and pragmatics of modalities Social behavior Dynamics of individual vs. group behavior Topic of attention, functional role Turn management, sequencing, feedback Interaction loops at multiple levels vs. high level dialogue Level of embodiment (robot / ECA) Temporal relations between modalities Cultural & individual differences Naturaleness of corpora Mapping between different schemes Complementarity between manual & automatic annotations Emotion related states & mm behavior (expressivity) Workshop on Emotional Corpora (L. Devillers, J. C. Martin, E. Cowie, R. Cowie, A. Batliner) 4

2006 Summary • Practical questions – Methodological steps (basic functions vs. Full-fledged complexity) – Dissemination/availability of corpora (Grenoble, Norway, …) – Cooperations (e. g. meetings, multilinguality) 5

2006 Summary • Cross disciplinary: linguists, computer sc. , … • International projects: HUMAINE, Similar, AMI, CHIL, CALO, ATR • Towards « standards » – Abstract coding: gesture, facial expr. , – Language • W 3 C EMMA • Emotion EARL (cf WS Emotions) – Tools : Anvil used a lot • Decrease of participation ? 6

Next steps • Related meetings – – LREC 2008 / Interspeech / Intelligent Virtual Agents Other Communities (e. g. expressive robotic) IPRA 07 : more theoretical incl. WS Multimodal pragmatics & corpus ICMI 07 : more technological, evaluation + application of mm corpora • Topic of next Multimodal WS – – – – – From corpora to application / studying phenomena Data driven models Standardisation Tools usability Animated character as perceptual tools Focused scheme vs exploratory scheme Machine Learning (ex export from annotations to WEKA) Manual and automatic annotations Cooperation HH vs HCI • Scientific maturity, Special issue of journal with open call 7
