2nd Call for Participation
for the IGGSA Shared Task on German Sentiment Analysis



We are pleased to announce the IGGSA (Interest Group on German Sentiment 
Analysis) Shared Task on German Sentiment Analysis. It is open to any 
interested participants from both academia and industry.


Introduction
Sentiment analysis and opinion mining have received increasing attention 
both in the scientific community as well as in industry. Use cases 
include the analysis of products, marketing campaigns, brands, 
companies, political speeches and more. However, most work has been 
performed on the English language. With this shared task, we put a focus 
on German. We offer fine-grained analysis tasks in two different 
domains: political speeches on the one hand, and product reviews on the 
other.


Task Description
The shared task consists of two main tasks:


Main Task 1:
Sentiment Analysis on German speeches from the Swiss parliament


Full task:
Identification of subjective expressions with source and targets.


Subtask 1a:
Subjective expressions are given, the task is to identify opinion sources.


Subtask 1b:
Subjective expressions are given, the task is to identify the opinion 
targets.


Main Task 2:
Cross-Domain Sentiment Analysis on German product reviews from Amazon.


Subtask 2a:
Identify subjective phrases.


Subtask 2b:
Identify aspect phrases.


Subtask 2c:
Identify subjective phrases and aspect phrases and indicate for each 
aspect phrase which subjective phrase it is the target of (if any).

Data sets
All tasks are evaluated on unseen test data. For main task 1, the data 
set consists of 600 sentences representing continuous segments of 25 
speeches on 9 different topics given before the Swiss parliament. For 
main task 2, the test data will be in the same format as the USAGE data 
set, which serves as training data (it consists of annotations for more 
than 600 reviews, http://dx.doi.org/10.4119/unibi/citec.2014.14). The 
test data will be from a different household product category than the 
ones included in the USAGE data set.


Trial data are already available for both main tasks.
For main task 2, the full training data is available, too.
