SimpleNLG-ZH

SimpleNLG-ZH is a realisation engine for Mandarin that follows the software design paradigm of SimpleNLG, i.e., keeping a clear separation between morphological and syntactic operations. Mandarin, as a highly analytical language, needs far fewer morphological operations but many more syntactic constraints than English. SimpleNLG-ZH (“Zhongwen” is Mandarin for “Chinese'”) was first built as a realiser for generating referring expressions in Mandarin which are mostly noun phrases together with simple verb phrases, and then extended to cover other constructions and phenomena in Mandarin. The current version of SimpleNLG-ZH was developed as an adaptation from V4.4.8 of the original SimpleNLG-EN.

Joint Sentiment-Topic (JST) Model

The joint sentiment-topic (JST) model is a weakly-supervised hierarchical Bayesian model for detecting document-level sentiment and extracting sentiment-bearing topics from text simultaneously. The only supervision used for JST learning is a small set of domain-independent sentiment clues; no labelled documents are used.

The JST source code (written in C++) can be downloaded here.
