Formal Concept Analysis For Ontology Engineering The Orpailleur team offers a 1-year post-doctoral position in Nancy, France, starting in Autumn 2014. This project aims at improving existing tools and developing new tools based on Formal Concept Analysis for building ontologies from structured textual data. Several tracks could be explored. One of them consists in studying the reduction of a concept lattices, i.e. check whether the high number of concepts in a concept lattice can be only represented by attribute concepts and object concepts (also known as the AOC-poset, which can provide a good conceptualization of the domain). Another track aims at using extensions of Formal Concept Analysis, namely Relational Concept Analysis and Pattern Structures, to model more complex phenomena in knowledge representation (such as relational aspects). Moreover, providing domain experts with interaction facilities at the lattice level, introducing metrics in the lattice (stability...) are also other possible directions of investigation. The work will involve both theoretical and programming aspects leading to the development of a running prototype. Candidates applying for this position should have a PhD in Computer Sciences with a good background in Knowledge Discovery (Formal Concept Analysis) and Knowledge Representation. In addition, abilities and experience in programming in C, C++ or Java are wished. This work comes within the scope of the "Hybride ANR Project" which aims at extracting from PubMed texts some knowledge about rares diseases. The candidate will have to work jointly with another post-doc researcher on Natural Language Processing that will be in charge of producing structured data from texts. LORIA lab is located in Nancy, East of France. It is among the largest computer science research laboratories in France involving several research organizations such as CNRS, INRIA Nancy Grand Est and Lorraine University. It is a very large and challenging research environment with 29 research teams and excellent computing facilities. Working languages are French or English. Contact : Yannick.Toussaint@loria.fr
