IRT SystemX and LIMSI offer 3-year PHD funding at Orsay (near Paris,

Subject :
Today the number of documents increases rapidly, and moreover they are
produced by multiple sources that can be classified by type (texts,
speech...), by style (blog, forum, tweet, broadcast news, broadcast
conversations, community tv...) and by language (English, French,
Chinese...). Reliability of the information contained in these documents
depends on each kind of source. Thus, selecting relevant and reliable
information from such documents and summarizing it is problematic.

The goal of the project is to build knowledge bases about persons,
products... (i.e. Named Entities). Knowledge will be extracted from
multiple documents and will have to be combined by aggregation and data
fusion. Thus the information will result from multi-source, multilingual
and multimedia document extraction:

- Multi-source: various types of documents (spontaneous, prepared...)
  and providers of documents (institution, individual, community...);
- Multimedia: texts, speech, scanned documents;
- Multilingual: different languages.

The work will focus on information identification, extraction and 
structuring. Studied issues will be:

- assessment of information reliability;
- assessment of information relevance (degree of novelty, scarcity of
- detection and classification of contradictions.

The PHD student will handle participation in international evaluation

The main location of the PHD student will be IRT, and s/he will be
supervised by LIMSI senior researchers.
