NLP taxonomy release. In the file taxonomy.csv, we include the taxonomy with 320 topics in a tree structure. The topic ID for each topic shows the parent node. For example, 233 (Relation Extraction) has a parent node to be 23 (Part of Speech Tagging), and topic 23 has its parent node to be 2 (Language Modeling, Syntax, Parsing).

• Topic ID: Id of topic.
• Topic: topic name.
