Keyword assignment vs. extraction
Keyword assignment methods can be roughly divided into:
- keyword assignment (keywords are chosen from controlled vocabulary or taxonomy) and
- keyword extraction (keywords are chosen from words that are explicitly mentioned in original text).
Methods for automatic keyword extraction can be supervised, semi-supervised, or unsupervised.[1][2] Unsupervised methods can be further divided into simple statistics, linguistics or graph-based, or ensemble methods that combine some or most of these methods. [3]
