A Simple Approach to Case-Based Reasoning in Knowledge Bases
Table 4: Link prediction results on NELL-995 for few shot relations.

As mentioned before, our CBR based approach needs no training and gathers reasoning patterns from few similar entities. Therefore, it should ideally perform well for query relations for which we do not have a lot of data. Recently, lv2019adapting studied this problem and propose a meta-learning finn2017model based solution (Meta-KGR) for few-shot relations. We compare with their model to see if CBR based approach will be able to generalize for such few-shot relations.
