• We also used GERBIL for benchmarking system for question answering

Available Annotators

(*) Annotator isn't available any more

Supported Experiments for each Annotator

The following table lists the annotators that are currently available and the experiment types they support. Note that some of the A2KB annotators support the D2KB experiment by offering an own API method. Other A2KB annotators can be chosen for a D2KB experiment as well as described in the wiki. However, since the comparison might not be fair, we marked these annotators with (✔) in the table. The same is done for Entity Typing.

Long term stability

The idea of GERBIL emerged in September 2014 when a couple of articles released at the same time claimed to be state-of-the-art. Especially, those approaches were not easily comparable due to their heterogeneous set-up, dataset use and evaluation metrics. Thus, we decided to build GERBIL and extend the BAT-Framework to break the barriers for people not able to write source code.

GERBIL is now more than 3 years old and has hosted more than 50.000 experiments. It is currently hosted at the research and development unit of the University Leipzig Computation Center and the Paderborn University which keep daily backups to ensure long-term quotability.

The survey data from our paper can be found at GERBIL's GitHub repository.
