Come join me as I speak with Professor Katrin Erk, a professor of Computational Linguistics at the University of Texas at Austin. We explore what sparked her initial interest in this field, as well as her specialty in computational semantics. We learn about the challenges of understanding the meaning of sentences, and how formal logical structures and machine learning can be very helpful in certain situations, but can't always handle more nuanced or longer stretches of text. I was especially intrigued by how Professor Erk illustrates these challenges through her research on how advice in various on-line forums can take on different and nuanced forms!
