My research interests broadly span two areas and more specifically their intersection: Computational linguistics and Complex Networks. I study language and related cognitive phenomena from the perspective of a dynamic and adaptive complex system. Complex network is a very promising and powerful tool in modeling complex systems, and hence, I model and study linguistic networks at various levels of linguistic organizations (e.g., sounds, words, meaning, and so on). Recently, I have been fascinated by the fact that web search queries are evolving and becoming more complex both syntactically and semantically; I am investigating their sturctural properties, which leads to me to believe that they represent an evolving protolanguage that will soon crystallize into a full-fledged language with its own structural properties.
I am also interested in computational linguistics and natural language processing for resource-poor languages, including unsupervised and semisupervised machine learning techniques for building tools, and innovative techniques for language resource creation.
