Sentiment Analysis is one of the most popular and exciting research areas in natural language processing. It deals with the identification and extraction of opinions, emotions and appraisals from a given input stream (e.g. text documents, product reviews, micro-blogging services or speech). While Sentiment Analysis is a highly active research area in the English (and international) community, there are rarely research collaborations and resources available focusing on German.
IGGSA, the Interest Group on German Sentiment Analysis, is a European research collaboration working on German Sentiment Analysis. The activities of IGGSA range from theory to applications of computer-aided opinion mining, sentiment analysis, polarity detection and affective computing. While the members of this project assume various viewpoints of sentiment analysis, they ultimately all work within a common research area, making this endeavor an exciting and interesting collaboration.
Inter-communication and resources are the keywords within this research group, but also services which may be offered amongst interested parties and academic-related communities. Our short-term goal is to work intensively on available resources (dictionaries, lexicons and corpora), and improve their quality and acceptability by the research community. The main target language is German, and obviously the German community, since the number of German benchmark collections, corpora, subjectivity dictionaries or other resources is rather limited.
A first milestone of this research collaboration was the creation of a first gold standard benchmark collection for German, allowing a coherent and comparable evaluation of sentiment analysis algorithms and systems.
