Some Annotated References in Relation to Knowledge-based Artificial Intelligence
Distant supervision, earlier or alternatively called self-supervision or weakly-supervised, is a method to use knowledge bases to label entities automatically in text, which is then used to extract features and train a machine learning classifier. The knowledge bases provide coherent positive training examples and avoid the high cost and effort of manual labelling. The method is generally more effective than unsupervised learning, though with similar reduced upfront effort. Large knowledge bases such as Wikipedia or Freebase are often used as the KB basis.
The first acknowledged use of distant supervision was Craven and Kumlien in 1999 (#11 below, though they used the term weak supervision); the first use of the formal term distant supervision was in Mintz et al. in 2009 (#21 below). Since then, the field has been a very active area of research.

(Uses a method that discovers relations from unstructured text as well as finding a list of discriminative patterns for each discovered relation. An informed feature generation technique based on dependency trees can significantly improve clustering quality, as measured by the F-score. This paper uses Unsupervised Relation Extraction (URE), based on the latent relation hypothesis that states that pairs of words that co-occur in similar patterns tend to have similar relations. This paper discovers and ranks the patterns behind the relations.)
