Automatic target validation based on neuroscientific literature mining for tractography
Jean-Cédric Chappelier, Sean Lewis Hill, Jocelyne Bloch, Bogdan Draganski, Renaud Luc Richardet, Xavier Vasques, David Slater
Target identification for tractography studies requires solid anatomical knowledge validated by an extensive literature review across species for each seed structure to be studied. Manual literature review to identify targets for a given seed region is ted ...
Frontiers Research Foundation2015Large-scale extraction of brain connectivity from the neuroscientific literature
Jean-Cédric Chappelier, Sean Lewis Hill, Martin Telefont, Renaud Luc Richardet
In neuroscience, as in many other scientific domains, the primary form of knowledge dissemination is through published articles. One challenge for modern neuroinformatics is finding methods to make the knowledge from the tremendous backlog of publications ...
Oxford Univ Press2015Agile text mining with Sherlok
Jean-Cédric Chappelier, Sean Lewis Hill, Renaud Luc Richardet
The successful development of an intelligent text mining application requires the collaboration of two main stakeholders: subject matter experts and text miners. In this paper, we describe a new methodology, agile text mining to improve that collaboration. ...
IEEE2015Integration of Online Learning into HTN Planning for Robotic Tasks
Francesco Mondada, Jean-Cédric Chappelier, Stéphane Magnenat
This paper extends hierarchical task network (HTN) planning with lightweight learning, considering that in robotics, actions have a non-zero probability of failing. Our work applies to A*-based HTN planners with lifting. We prove that the planner finds the ...
2012Utilisation de PLSI en recherche d'information
Jean-Cédric Chappelier, Emmanuel Eckard
The PLSI model (“Probabilistic Latent Semantic Indexing”) offers a document indexing scheme based on probabilistic latent category models. It entailed applications in diverse fields, notably in information retrieval (IR). Nevertheless, PLSI cannot process d ...
2009PLSI: the true Fisher Kernel and beyond
Jean-Cédric Chappelier, Emmanuel Eckard
The Probalistic Latent Semantic Indexing model, introduced by T. Hofmann (1999), has engendered applications in numerous fields, notably document classification and information retrieval. In this context, the Fisher kernel was found to be an appropriate do ...

Jean-Cédric Chappelier, Emmanuel Eckard
ABSTRACT. An information-geometric approach for document similarities in the framework of “Probabilistic Latent Semantic Indexing” was first proposed by T. Hofmann (2000) and later extended (“revisited”) by Nyffenegger et al. (2006). This paper presents an ...
2009An Ad Hoc Information Retrieval Perspective on PLSI through language model identification
Jean-Cédric Chappelier, Emmanuel Eckard
Ten years ago, PLSI opened the road to probabilistic latent semantic representations of documents. It led to a number of applications in different fields, including ad hoc Information Retrieval. However, inherent limitations hinder its use on documents not ...

Jean-Cédric Chappelier, Emmanuel Eckard
The document provides an overview of the main Free ("Open Source") software of interest for research in Information Retrieval, as well as some background on the context. I provides a guideline for choosing appropriate tools. ...
