Never Ending Language Learning (NELL)

This dataset provides version 1115 of the belief extracted by CMU's Never Ending Language Learner (NELL) and version 1110 of the candidate belief extracted by NELL. See rtw.ml.cmu.edu/rtw/overview. NELL is an open information extraction system that attempts to read the Clueweb09 of 500 million web pages (boston.lti.cs.cmu.edu/Data/clueweb09/) and general web searches.

The dataset has 4 configurations: nell_belief, nell_candidate, nell_belief_sentences, and nell_candidate_sentences. nell_belief is certainties of belief are lower. The two sentences config extracts the CPL sentence patterns filled with the applicable 'best' literal string for the entities filled into the sentence patterns. And also provides sentences found using web searches containing the entities and relationships.
