Comparison

The two papers describe essentially the same algorithm of classification of terms into three categories: Positive, Negative and Objective, thereby combining two separate problems: term subjectivity and term orientation for opinion mining applications. The semi-supervised learning is used to build a labeled set of examples from the three categories. WordNet glosses are used to build vectorial representation for each synset. Then, standard supervised learning algorithms are employed to label the WordNet terms.

There are two differences in these approaches: (1) while the EACL paper uses synonymy and direct antonymy between terms to propagate labels in semi-supervised stage, the LREC paper is navigating the relations of direct antonymy, similarity, derivedfrom, pertains-to, attribute, and also-see relations. (2) in the EACL paper the authors compare three different supervised classifiers, while in the LREC paper they use the ensemble of these classifiers.

Both papers have the same 'Big idea', use the same datasets and aim to solve the same problem. The main difference is the focus of the papers: while the EACL paper presents the novel approach to the opinion mining problem solution, the LREC paper provides useful resources obtained from this work: the SentiWordNet and the visualization tool.
