Curriculum Vitae

PhD Thesis

  

Hello, I am Alexander, a postdoctoral researcher in Natural Language Processing at University of Hamburg working with Prof. Chris Biemann. My main research interest is computational lexical semantics, including semantic similarity, word sense induction and disambiguation. In the past I worked also on other NLP-related topics including short text classification for social media analysis (sentiment analysis, topic categorization, gender categorization, age detection) and skill extraction from text. More generally, I am interested in statistical natural language processing, information retrieval, semantic web, machine learning and interections of any interactions of these fields.

To get a better idea about my research please try two following demos: Serelex, a lexico-semantic search engine, Elisit, a skill extraction system. You can also may find something intersting in my PhD dissertation “Similarity Measures for Semantic Relation Extraction” or in one of the papers listed below. Let me know if you have any questions related to these papers.

I participate in program commitees of conferences dedicated to natural language processing, computational linguistics, data analysis and related fields. If you are looking for a reviewer do not hesistate to contact me.

Prior to Hamburg, I worked as a postdoc at TU Darmstadt. I have served as an associated researcher at Université catholique de Louvain and a researcher at Digital Society Laboratory LLC startup working on targeted advertisement based on social network data. I have completed a PhD in Natural Language Processing at Center for Natural Language Processing of Université catholique de Louvain under supervision of Prof. Cédrick Fairon and Prof. Andrey Philippovich in co-tutelle with Moscow State Technical University. During my studies I was involved in the European research project iCOP and the Belgian research project ELIS-IT. My research was supported by Wallonie-Bruxelles International.
