Description of the thesis topic

This PhD proposal is in the context of a European Project INODE – Intelligent Open Data Exploration.
The core principle of INODE is that users should interact with data in a more dialectic and intuitive way similar to a dialog with a human. To achieve this principle, INODE will offer a suite of agile, fit-for-purpose and sustainable services for exploration of data sets that help users (a) link and leverage multiple datasets, (b)access and search data using natural language, using examples and using analytics (c) get guidance from the system in understanding the data and formulating the right queries, and (d) explore data and discover new insights through visualizations.

The topic of this PhD is to develop a formalization, algorithms and a validation for guided exploration to help users reach their goal. Users differ from each other in their knowledge of the data and their technical level that determines the way they will explore data.

This work will be in collaboration with three use case providers: (a) Cancer Biomarker Research - SIB
Swiss Institute of Bioinformatics, Switzerland, (b) Research and Innovation Policy Making - SIRIS, Spain, and (c) Astrophysics - Max Planck Institute for Extraterrestrial Physics, Germany. The candidate will develop a general framework consisting of the following tasks:
1. Formalization: Data Access and Exploration Operators, Exploration Framework.
2. Algorithms: Fully and partially-Guided Exploration
3. Validation: Use Cases with various goals

Work Context

The Laboratoire d'Informatique de Grenoble ( is a research unit in fundamental and applied computing. Organized into 24 research teams, it brings together nearly 500 users (researchers, doctoral students, support staff and trainees). It is under the supervision of the CNRS, Grenoble INP and the University of Grenoble Alpes.
It is located on the St Martin D'Hères campus in a building that houses three other mixed units. Nine teams are shared with INRIA, including five housed in Montbonnot and two on the scientific peninsula.
