Victor Soto


I am a fifth year PhD student in Computer Science at Columbia University working with Professor Julia Hirschberg. My research goal is to extend current NLP methods and design new ones for code-switched language. Currently I'm focusing on discovering mixed-language web resources, and neural part-of-speech tagging and language modeling for English-Spanish sentences. You can find my CV here.
