CRF-ADF Sequential Tagging Toolkit v1.0

This is a general purpose software for sequential tagging (or called sequential labelling, linear-chain structured classification). The CRF (Conditional Random Fields) model is described in (Lafferty et al., 2001) and the ADF (Adaptive stochastic gradient Decent based on Feature-frequency information) fast training algorithm is described in (Sun et al., ACL 2012).

Latent Structured Perceptron Toolkit v1.0

This is a general purpose software for sequential tagging with the emphasis on fast training speed. This toolkit includes Latent Structured Perceptron (LSP) model (Sun et al., IJCAI 2009, TKDE 2013). It also includes traditional Structured Perceptron (SP) model and with the averaged version (Collins, 2002).

Online Multi-Task Learning Toolkit (OMT) v1.0

This is a general purpose software for online multi-task learning. The online multi-task learning is mainly based on Conditional Random Fields (CRF) model and Stochastic Gradient Descent (SGD) training. The work is described in (Sun et al., TKDE 2013).
