German ClimaPinion

Overview

This DecarboNet opinion mining service aims to annotate German language documents with sentiment related to climate change. The web service takes as input a document or set of documents, and outputs those documents as JSON documents of standoff annotations with opinion, term and URI information (see the API documentation for more details). Sentiment is classified into positive, negative and neutral polarity, as well as more fine-grained emotions such as fear, anger, joy etc. The target of the opinion is also recognised if present. Climate-related terms are also matched and linked to the instance of that term in relevant Linked Open Data ontologies.

Note that the current version of the tool is tuned towards precision. This means that it may not find all instances of sentiment.
