Post-doctoral position at LIMSI-CNRS, Paris Sud University LIMSI is a multi-disciplinary research unit that addresses the automatic processing of human language for a range of tasks. LIMSI invites applications for a one-year Postdoctoral position. We are seeking researchers with interests in combining statistical learning, structured Information Retrieval, and text/data mining. The postdoctoral fellow will contribute to a project funded by ANR addressing information retrieval in the biomedical domain. Medical cases are described through natural language texts. Each case is described by a set of reports. The goal of this work is to look for similar cases. This functionality targets medical doctors who will define the type of search they are interested in. A representation of each case will be built, including structure and content. It can rely on various levels of analysis, including medical entities detected in the texts, leading to multiple views of a case. Search methods will be proposed to identify globally similar cases or cases which contain similar parts according to some dimension. The methods will rely both on text contents and on external knowledge bases. Monolingual and bilingual resources are available for this purpose. The proposed methods will be applicable to multiple languages, including English and French, and across languages, so that similar cases can be found jointly in two languages. Unsupervised methods, including topic models and clustering, are natural candidates to help represent the cases. The work will be performed in the framework of a collaborative project involving partners in medicine, natural language processing, and knowledge engineering. Job requirements: Applicants must hold a PhD in Computer Science (Machine Learning, Information Retrieval, or Natural Language Processing, with a good command of statistical methods).
