PhD students
Mondeca sponsors doctoral students in collaboration with academic institutions. This allows the company to stay at the cutting edge of research in semantic technologies. The following students have been sponsored by Mondeca:
-
Charles Teissèdre - PhD Student - 2009-2012
In collaboration with MoDyCo (University Paris Ouest Nanterre La Défense)
Thesis : Semantic Web and Linguistic Temporality: towards new ways to access text(s)
This research project proposes to tackle the problem of the access to the informational contents of the numerical texts, via criteria related to the expression of temporality in the texts. The aiming of the project is double: it is a question of reconciling a conceptual and operational approach, from the linguistic point of view, and an applicative approach, whose objective is to take part in making of new tools of access the text(s), while being based on technologies resulting from the work undertaken around the Semantic Web. It is thus at the same time a question of implementing systems of interaction with the users and of managing to model and represent the textual structuring issued by the analysis of temporality, in order to enrich quality of these systems of interaction.

Dr. Pierre-Yves Vandenbussche - 2008-2011
In collaboration with SPIM-INSERM (University Pierre et Marie Curie - Paris 6)
Thesis: The design and the implementation of an Information resources meta-model and its services : application to the medical field.
Considering a specific field, information resources are available in different organizational systems: ontological, terminological, thesauri... Information resources design in a structured formal method will improve:
- interoperability among resources and software applications, e.g. input/output of this framework (APIs, web services, serialisations...) as an application server or as a referential.
- knowledge segmentations in levels of expression, e.g. depending on the complexity, the formalisation of areferential and their interactions. This segmentation will offer more significant services in regard of the level aimed.See also : Pierre-Yves' website , SPIM website

Dr. Laurence Noel - 2006-2010
In collaboration with Leden (University Paris 8 Vincennes-St Denis)
This Ph. D. thesis aims at exploiting semantically annotated data to improve user experience concerning information access and knowledge acquisition by the end-user. This work will attempt to define articulation modes between two types of systems : one based on a formal representation of knowledge and the other one based on a hypermedia representation of information. The goal is to answer the following user needs:
- exploring and discovering the information space (transversal navigation and exploratory search)
- comparing the elements in this information space (information hierarchisation and contextualisation of data according to four display modes: spatial, temporal, thematic, and iconic)
- selecting and reorganizing those elements according to personal criteria (interface adaptation and data appropriation) -
Dr. Olivier Carloni - 2005-2008
In collaboration with LIRMM (Université de Montpellier II)
The purpose of this Ph.D. is to provide reasoning capabilities to ITM, the knowledge base management system designed by Mondeca. One characteristic of this work is to build these reasoning mechanisms using graph theory operations. At the end, the reasoning system should permit:
(1) import and export of knowledge serialized using web semantic standards (more precisely Topics Maps (ISO standard)).
(2) knowledge internal ITM description, storage and management using ITM labeled hypergraph formalism,
(3) the full processing of this knowledge using conceptual graphs formalism.

Dr. Florence Amardeilh - 2003-2007
In collaboration with MoDyCo (University Paris Ouest Nanterre La Défense)
Thesis: Semantic Web and Computational Linguistic: methodological proposals and conception of a software platform.
This thesis deals with the issues related to semantic annotation and ontology population within the framework defined by the Semantic Web. The idea suggested here is to combine the Information Extraction tools with the SW knowledge representation tools, such as ITM from Mondeca. But there is currently a gap between the representation formats used by these tools. This thesis proposes to fill this gap by designing a mediator able to:
- Semi-automatically create of multilingual domain vocabularies/terminologies from a representative corpus of textual documents
- Semi-automatically enrich a knowledge base with the named entities and semantic relations extracted from the textual documents
- Semantically annotate those documents with the concepts modelled by the reference ontology -
Dr. Pascal Auillans - 2000-2005
In collaboration with LaBRI (University Bordeaux I)
Our work deals with a new document indexation language, called XTM (XML topic maps). This language, defined by a XML grammar, allows the document indexing, the definition of relations between indexes and the semantisation of these relations. This language therefore permits the construction of a tagged hypergraph of an index.
We are interested at various graph theory issues to answer the needs of this new language's users.
