2012-12-32 Supervised learning-based relation extraction As discussed above relation extraction methods are classified into three categories The difference between feature-based and kernel-based methods is shown in the following Figure 1 With respect to machine learning procedure these two are different from semi-supervised learning methods
2009-9-30Semi-Supervised Laplacian Regularization of KCCA 5 where R x^ = xK ^xx^ + x m2 x K ^xx^L x^K ^xx^ and L ^x is the empirical graph Laplacian estimated from the m xsamples of labeled and unlabeled data 4 2 The General Case In the general case we have more than two modalities
Labeling of data is often difficult expensive and time consuming since efforts of experienced human annotators are required and often we have large number of samples and noisy data Co-training is a practical and powerful semi-supervised learning method as it yields high classification accuracy with a training data set containing only a small set of labeled data For successful co-training
2020-7-9A semi-supervised model is proposed for extracting clinical terms of Traditional Chinese Medicine using feature words The extraction model is based on BiLSTM-CRF and combined with semi-supervised learning and feature word set which reduces the cost of manual annotation and leverage extraction results Experiment results show that the proposed model improves the extraction of five
