My research interests revolve around theoretical and applied issues pertaining to how data and information are accessed, represented, utilised and disseminated. An earlier part of my research career focused on building methods and prototypes to process textual data so as to to produce knowledge enhancing artifacts and map the evolution of research topics contained therein. This was done using automated techniques, namely a mixture of symbolic (Natural Language Processing and Computational Terminology) and numeric approaches (statistical and mathematical models). Applications targeted were text mining, knowledge acquisition, terminology structuring, information Visualisation and Information Retrieval.
In recent years, I have stepped back from this applied research to try and examine critically the theoretical and epistemological underpinnings of such traditions of corpus-based empirical research. This has led me to become interested in the history and philosophy of science, in epistemology and in the theoretical foundations of Information and Communication sciences, the discipline under which my research falls in France.
The cSquares initiative is part of my foray into the the conceptions of communication as seen by students, using an arts-informed approach which is novel for me.
I have also been looking at the uses of ICTs and became interested in how the current phenomena of Big Data and Open Data are transforming entire sectors of the society and their impact on scientific inquiry. Hence, haven been involved in empirical research on developing information systems, I am now looking at how this technology affects the way we do things as a society and as scientists. The questions that I am particularly interested in are:
i) what transformations are underway that can be attributed to advancements in the field of ICT?
(ii) What are the epistemological and theoretical implications of a data-driven scientific discovery or decision making?
Of course, one cannot make sweeping statements about the impact of ICTs for the entire society or for all of the scientific disciplines but there may be recurring patterns and implications across entire sectors and fields which I am keen to uncover.

If I were to draw a list, I might include the following:
- Information & Communication Sciences theories
- History and Foundations of Library & Information Science
- Usage of ICTs (Information and Communication Technology)
- Impact of technology on science and society
- Big Data, Open Data and Web 2.0
- Epistemology and history of science (Science and Technology Studies)
- Information retrieval
- Textmining
- Knowledge acquisition & representation from texts
- Human Language Technology Evaluation
Tools
I co-developed a text mining platform called TermWatch that takes in a corpus of electronic texts, runs them through programs that perform :
The result can be viewed in two ways :
- term-extraction
- term-filtering
- syntactic and semantic variant identification
- hierarchical clustering using our own home-grown hierarchical clustering algorithm (CPCL).
The result can be viewed in two ways :
- as an HTML navigational database;
- in a graph form using an external Information Visualization package.
