Informal sentiment analysis in multiple domains for English and Spanish

Informal sentiment analysis in multiple domains for English and Spanish

This video was recorded at 15th International Multiconference on Information Society, Ljubljana 2012. This paper addresses the problem of sentiment analysis in an informal setting in multiple domains and in two languages. We explore the influence of using background knowledge in the form of different sentiment lexicons, as well as the influence of various lexical surface features. We show that the improvement resulting from using a two-layer model, sentiment lexicons, surface features and feature scaling is most notable on social media datasets in both English and Spanish. For English, we are also able to demonstrate improvement on the news domain using sentiment lexicons and a large improvement on the social media domain. We also demonstrate that domain-specific lexicons bring comparable performance to generalpurpose lexicons.
