Summary
This paper describes a Conditional Random Fields approach to the Arabic Named Entity Recognition problem. ANERcorp
In this paper the authors used Conditional Random Fields
Previous to this paper, the authors were using Maximum Entropy model with binary features which uses the word itself, the preceding word, the bigrams around the word and external resources. Furthermore in order to ease the difficulty of detecting the named entities, they used a 2-step approach where the first steps focused on detecting the entities and the second step classifies them. person, location, organization and miscellaneous.
