I am a PhD student at Language Technologies Institute. What I hope to get out of this Social Media Analysis class is to learn the methods and tools that have been or can be used for analyzing and understanding social media. I am also interested on how the tools (sub-systems) used in the project I am currently involved in: NELL can be adapted for use on social media domain (for example to build a Knowledge Base based on a social media), or how its Knowledge Base can be used as a resource to analyze and/or understand social media.

My research interest is in the area of information retrieval, machine learning, and natural language processing. I am currently involved in the Read The Web project that builds a system called NELL which tries to learn overtime to 'read' (automatically extract facts and build a Knowledge Base of these facts) from the Web. Previously I was involved in the e-LICO project, specifically in the building of an ontology of data mining algorithms and models. I have also worked previously on the area of opinion mining and graph clustering.
