1st Call for Participation
for the IGGSA Shared Task on German Sentiment Analysis




We are pleased to announce the IGGSA 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 caught 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 the German language, both for analysing product reviews as well as 
political speeches in a fine-grained manner.


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 product category than the ones 
included in the USAGE data set.
