New NLP Taxonomy
We use a classification scheme, CLICKER, for NLP resources. This scheme is based on an analysis of online lectures from 77 university-level NLP courses. The latest version of the classification scheme (taxonomy) includes 320 topics. It is intended to label educational materials and not so much research papers.

aan.how is currently 403 Forbidden. It is a wonderful database and helped me a lot with gathering resources. I wonder what has happened to it.
