I am extremely happy to announce that a paper written by Yannick Versley and me was accepted at NAACL HLT 2015:

Michael Haas and Yannick Versley (2015) Subsentential Sentiment on a Shoestring: A Crosslingual Analysis of Compositional Classification. In Proceedings of NAACL-HLT 2015.

The submission is partially based on my master's thesis. We will also release the Heidelberg Sentiment Treebank after the conference. HeiST is our German dataset for compositional sentiment analysis.
