[Corpora-List] post-doctoral position at LIMSI (Orsay, France)

[Gilles Adda]

    Post-doc position at LIMSI-CNRS in the Spoken Language Processing group

A post-doc position will be proposed at LIMSI-CNRS, in the context of 
the ANR-funded CHIST-ERA CAMOMILE Project (Collaborative Annotation of 
multi-MOdal, MultI-Lingual and multi-mEdia documents).


      Description

Human activity is constantly generating large volumes of heterogeneous 
data, in particular via the Web. These data can be collected and 
explored to gain new insights in social sciences, linguistics, 
economics, behavioural studies as well as artificial intelligence and 
computer sciences.
In this regard, 3M (multimodal, multimedia, multilingual) data could be 
seen as a paradigm of sharing an object of study, human data, between 
many scientific domains. But, to be really useful, these data should be 
annotated, and available in very large amounts. Annotated data is useful 
for computer sciences which process human data with statistical-based 
machine learning methods, but also for social sciences which are more 
and more using the large corpora available to support new insights, in a 
way which was not imaginable few years ago. However, annotating data is 
costly as it involves a large amount of manual work, and in this regard 
3M data, for which we need to annotate different modalities with 
different levels of abstraction is especially costly. Current annotation 
framework involves some local manual annotation, with the help sometimes 
of some automatic tools (mainly pre-segmentation).
The project aims at developing a first prototype of collaborative 
annotation framework on 3M data, in which the manual annotation will be 
done remotely on many sites, while the final annotation will be 
localized on the main site. Furthermore, with the same principle, some 
systems devoted to automatic processing of the modalities (speech, 
vision) present in the multimedia data will help the transcription, by 
producing automatic annotations. These automatic annotations are done 
remotely in each expertise point, which will be then combined locally to 
produce a meaningful help to the annotators.
In order to develop this new annotation concept, we will test it on a 
practical case study: the problem of person annotation (who is 
speaking?, who is seen?) in video, which needs collaboration of high 
level automatic systems dealing with different media (video, speech, 
audio tracks, OCR, ...). The quality of the annotated data will be 
evaluated through the task of person retrieval.
This new way to envision the annotation process, should lead to some 
methodologies, tools, instruments and data that are useful for the whole 
scientific community who have interest in 3M annotated data.
