I am doing a research study on some of the most recent Chinese Sentiment Analysis tools. My purpose is to evaluate the analysis results of each tool on a set of sentences – I am looking for sentence-level analysis instead of document-level analysis. The set of sentences would be randomly selected from social networking sites, i.e. the sentences will most likely be colloquial. In particular, I am looking for tools (at least 4) with the following specifications:
- The analysis scale must have at least two values, i.e. positive or negative. (I believe this is true for all sentiment analysis tools...just in case)
- The tool could preferably obtain a sentiment score for any Chinese sentences, i.e. the dataset it uses is large enough to cover most of the commonly used words.
- The tool is preferably open-source.
- The tool is preferably an SDK or API.
Thanks in advance!
