The item-based recommender cannot parse the dataset. #20

Closed andreas-dai closed 10 years ago

andreas-dai commented 10 years ago

Trying the run the orchestrator example, it seems to me that the reference-framework example does not work because the item-based recommender (ItembasedRec_batch.java) does not support the current data format.

I checked out the reference framework from the repository and started an example run, using the command: sh orchestrator.sh 01.java/01.mahout/01.example/ 01.linux/01.centos/01.mahout/ 01.MovieTweetings/datasets/snapshots_10K/

When debugging the program code, the recommender algorithms seems to cause parse errors while reading the dataset.

The reference framework code was correctly working with the branch "ZeroMQ-poc". We now merged such branch with the master stream. It should be working now. Please let us know if it solved the issue.

Currently, I cannot verify the changes, because I have problem with python-zeromq because python complains about a missing Xserver import: unable to open X server.(as expected on a Windows system) Probably there is a problem with a package not suitable for Windows.

Nevertheless, the dataset parser defined in algorithms\01.java\01.mahout\01.example\src\main\java\dev\crowdrec\recs\mahout\ItembasedRec_batch.java still seems to expect an old data format.

Right, also the algorithm repository had the branch "ZeroMQ-poc". We merged also this branch to the master.

The orchestrator script works for me. I had to run dos2unix for the sh-scripts; but now it works fine.
