Tag community detection and recommendation

A Java project for community detection and recommendation.



This is a Java project implementing the framework for tag community detection method presented by Papadopoulos et al. in DaWaK 2010 (see references below for full citation). In addition, it contains several utility methods for performing tag recommendation and evaluating the method.



1. Download the rar archive here.

2. Unzip the archive in your Java workspace. You can directly import the folder as an Eclipse project.

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

4. Make sure that you make appropriate modifications to the class dawak2010.Config in order to point to the appropriate local paths.

5. You may run the class dawak2010.DaWak2010 to repeat the experiments reported in the paper.

6. The package graph.clust contains several variants of clustering algorithms that can be used stand-alone.

7. The aforementioned rar archive only contains the BIBSONOMY-200K dataset. If you are interested in experimented with the FLICKR-1M and DELICIOUS-7M datasets reported in the paper, download the following files, FLICKR-1M and DELICIOUS-7M, and extract them following a similar folder structure as BIBSONOMY-200K.
