jSRE is an open source Java tool for Relation Extraction. It is based on a supervised machine learning approach which is applicable even when (deep) linguistic processing is not available or reliable. In particular, jSRE uses a combination of kernel functions to integrate two different information sources: (i) the whole sentence where the relation appears, and (ii) the local contexts around the interacting entities. jSRE requires only a shallow linguistic processing, such as tokenization, sentence splitting, Part-of-Speech (PoS) tagging and lemmatization.
The core of jSRE is primarily developed by Claudio Giuliano at ITC-IRST, Cognitive and Communication Technologies division.
