CERTH @ MediaEval 2011 SED Tool

Social Event Detection (SED) in tagged photo collections

Description

This is a Java library implementing the framework presented by CERTH in the Social Event Detection task at MediaEval 2011. It can be used as a competing method for detecting events in large tagged photo collections. In addition, it contains several utility methods for loading the metadata (in the format distributed by the SED task organizers) and computing the performance of the method.

 

Instructions

1. Download the rar archive here.

2. Unzip the archive in your Java workspace. A sample class using the library is located in src\test\SubmissionTester.java.

3. Make sure that you include all libraries in the lib folder in your class path.

4. In the data folder there are several data files that are used by the implemented methods as "background" knowledge. You might be interested in tweaking those in order to examine their influence on the performance of the framework (for instance, the tag models used for classification of a photo into cities, the soccer topic and venue).

5. You may extend/override the abstract class SubmissionCreator.java in order to prepare your own solution to the problem of Social Event Detection.

6. You may use the Evaluator.java class in order to compute the performance of your method against a given ground truth.
