Snowball: Extracting Relations from Large Plain-Text Collections

This is my own implementation of the the Snowball system to bootstrap relationship instances. You can find more details here:

• Eugene Agichtein and Luis Gravano, Snowball: Extracting Relations from Large Plain-Text Collections. In Proceedings of the fifth ACM conference on Digital libraries. ACM, 200.

• H Yu, E Agichtein, Extracting synonymous gene and protein terms from biological literature. In Bioinformatics, 19(suppl 1), 2003 - Oxford University Press

NOTE: this version is not tested and might contain bugs/errors, I recommend you instead to look at the Python implementation of Snowball
