Alejandro Molina Villegas

PhD Computer Sciences

Temporary Lecturer and Researcher, University of Avignon, France

some_text I am an enthusiastic researcher on Data Mining and Statistical Methods applied to Natural language processing and linguistics engineering. My fields of expertise include Text Simplification, Discourse Analysis, Summarization, Web Mining, Citizen Science and Turing-like evaluation. I am currently working in a project dealing with Sentiment Analysis (with Xerox as partner) and I am applying for a funding, from the National Institutes of Health, to work in a project about NLP methods applied to Genomics.
