Max Ionov

Computational linguist: NLP, ML and other fancy acronyms


Language is one of the most interesting and challenging things to work with as a developer. Creating systems which can act as if they understand natural language is my job, my hobby and my passion. I have been in the field for more than 4 years balancing between academia and industry. Some random facts: — worked for 2 years as a computational linguist in Russian search engine. Tasks included query disambiguation and query classification (machine learning + relatively big data) — created an open-source tool for anaphora resolution (machine learning) for academic purposes For my work I primarily use Python with well-known libraries like nltk and scikit-learn although when system performance matters I'm not afraid to use less developer-friendly languages.
