[Air-L] Text Analytics and Social Media

We are exploring the application of text analytics to the analysis of social media - specifically semantic orientation, sentiment analysis, and ontology analysis - and are looking for sources of reputable research, particularly in ontology analysis. Is anyone aware of articles that compare models of ontology management in text analytics for social media? And, can deficits in the current research be identified?
