The AMIDA Automatic Content Linking Device (ACLD) is a just-in-time document retrieval system for meeting environments. The ACLD listens to a meeting and displays information about the documents from the group's history that are most relevant to what is being said. Participants can view an outline or the entire content of the documents , if they feel that(More)
We propose a method for computing semantic relatedness between words or texts by using knowledge from hypertext encyclopedias such as Wikipedia. A network of concepts is built by filtering the encyclopedia's articles, each concept corresponding to an article. Two types of weighted links between concepts are considered: one based on hyperlinks between the(More)
This paper describes an ISO project developing an international standard for annotating dialogue with semantic information, in particular concerning the communicative functions of the utterances, the kind of content they address, and the dependency relations to what was said and done earlier in the dialogue. The project, registered as ISO 24617-2 Semantic(More)
This article defines a Framework for Machine Translation Evaluation (FEMTI) which relates the quality model used to evaluate a machine translation system to the purpose and context of the system. Our proposal attempts to put together, into a coherent picture, previous attempts to structure a domain characterised by overall complexity and local difficulties.(More)
User-generated texts such as reviews, comments or discussions are valuable indicators of users' preferences. Unlike previous works which focus on labeled data from user-contributed reviews, we focus here on user comments which are not accompanied by explicit rating labels. We investigate their utility for a one-class collaborative filtering task such as(More)
This article describes an experiment in user query elicitation for the design of a multimodal meeting processing and retrieval system (MPR). In the experiment, participants are asked to choose between several scenarios of use of an MPR system, then formulate (on paper) queries to the system within the context of their chosen scenario. The analysis of the(More)
This article discusses the detection of dis-coursemarkers(DM)indialogtranscriptions, by human annotators and by automated means. After a theoretical discussion of the definitionofDMsandtheirrelevancetonatu-ral language processing, we focus on therole of like as a DM.

We describe the design, the evaluation setup, and the results of the 2016 WMT shared task on cross-lingual pronoun prediction. This is a classification task in which participants are asked to provide predictions on what pronoun class label should replace a placeholder value in the target-language text, provided in lemma-tised and PoS-tagged form. We(More)
This paper addresses the problem of keyword extraction from conversations, with the goal of using these keywords to retrieve, for each short conversation fragment, a small number of potentially relevant documents, which can be recommended to participants. However, even a short fragment contains a variety of words, which are potentially related to several(More)
