Relation Extraction via Unsupervised Learning
An unsupervised relation extraction is used to extract relations from the web when there is no labeled training data. After the strings of words are extracted a relation is only accepted if it meets syntactic and lexical constraints, and a confidence value is computed for each relation using a logistic regression extractor.
