Most pre-trained word embeddings are achieved from context-based learning algorithms trained over a large text corpus. This leads to learning similar vectors for words that share most of their contexts, while expressing different meanings. Therefore, the complex characteristics of words cannot be fully learned by using such models. One of the natural language processing applications that suffers from this problem is sentiment analysis. In this task, two words with opposite sentiments are not distinguished well by using common pre-trained word embeddings. This thesis addresses this problem and proposes two empirically effective approaches to learn word embeddings for sentiment analysis. The both approaches exploit sentiment lexicons and tak...
