Research Abstract

In recent years, semi-supervised learning has been receiving more and more attentions in natural language processing. Semi-supervised learning uses large-scale unlabeled data in addition to small number of labeled data (seed) to perform highly accurate statistical learning. This research project showed that the structure of graph affects the performance of semi-supervised methods in several tasks.
