Competition

During the development phase, submissions will be evaluated on the validation partition. Participants will receive immediate feedback on the performance of their submissions. During the final phase submissions will be evaluated on the test partition. Results in the final phase will be used to determine the final and official ranking. These are the evaluation measures computed:

The following evaluation measures will be used in each track

• Subtask 1. Precision, recall and f1-score with respect to the violent event class. The leading evaluation measure being f1-score.
• Subtask 2. Macro-average of Precision, recall and f1-score, macro-average of f1-score will be the leading evaluation measure for this subtask.

By registering to this competition you agree to use the data exclusively for the purpose of participation to this competition. Data cannot be shared or distributed under any condition.

By submitting results to this competition, you consent to the public release of your scores at the IberLEF workshop and in the associated proceedings, at the task organizers' discretion. Scores may include, but are not limited to, automatically and manually calculated quantitative judgements, qualitative judgements, and such other metrics as the task organizers see fit. You accept that the ultimate decision of metric choice and score value is that of the task organizers.

You further agree that if your team has several members, each of them will register to the competition and build a competition team (as described on the 'Overview' page) and that if you are a single participant you will build a team with a single member.

You further agree that the task organizers are under no obligation to release scores and that scores may be withheld if it is the task organizers' judgement that the submission was incomplete, erroneous, deceptive, or violated the letter or spirit of the competition's rules. Inclusion of a submission's scores is not an endorsement of a team or individual's submission, system, or science.

Each team can participate with up to five submissions for the final phase. During the validation phase a maximum of 100 submissions are allowed, 5 per day. Files to be uploaded must be compressed in a .zip file. This is the expected format for submissions:

Substask 1

Format for predictions is a CSV file with one prediction per line (0 for non-violent or 1 for violent) in the same order as the corresponding data files (i.e., line 1 in the prediction file must correspond to user 1 in the data file). The file must be in a .zip file for submission, please do not use folders.

Example:

0
1
0
1
1
1

...

Substask 2

Format for predictions is a CSV file with five predictions per line, each prediction is associated to a single category (1 for the presence of the category and 0 otherwise) use a comma "," separator between predictions in the same line. The order of categories is as follows: Accident, Homicide, Non-Violent-incident, Robbery, Kidnapping, for columns 1 to 5, respectively.  This order corresponds to the order available in trial and training data.  You should use the same order as the corresponding data files i.e., line 1 in the prediction file must correspond to user 1 in the data file). The file must be in a .zip file for submission, please do not use folders..

Example:

0,1,1,0,1
0,0,0,0,1
1,0,1,0,1
1,0,0,1,0
1,1,1,0,1
1,0,0,0,1

...

You can check development data to see the format for both data and submissions by looking into reference (ground-truth) files.
