'''PORE: Positive-Only Relation Extraction from Wikipedia Text''' - scientific work about [[Wikipedia quality]] published in 2007, written by [[Ganglin Wang]], [[Yong Yu]] and [[Haiping Zhu]].

== Overview ==
Extracting semantic relations is of great importance for the creation of the Semantic Web content. It is of great benefit to semi-automatically extract relations from the free text of [[Wikipedia]] using the structured content readily available in it. Pattern matching methods that employ information redundancy cannot work well since there is not much redundancy information in Wikipedia, compared to the Web. Multi-class classification methods are not reasonable since no classification of relation types is available in Wikipedia. In this paper, authors propose PORE (Positive-Only Relation Extraction), for relation extraction from Wikipedia text. The core algorithm B-POL extends a state-of-the-art positive-only learning algorithm using bootstrapping, strong negative identifi cation, and transductive inference to work with fewer positive training exam ples. Authors conducted experiments on several relations with different amount of training data. The experimental results show that B-POL can work effectively given only a small amount of positive training examples and it significantly out per forms the original positive learning approaches and a multi-class SVM. Furthermore, although PORE is applied in the context of [[Wiki]] pedia, the core algorithm B-POL is a general approach for Ontology Population and can be adapted to other domains.
