User Friendly Automatic Construction of Background Knowledge: Mode Construction from ER Diagrams
This work addresses the usability issue for domain experts in ILP systems, making it more accessible, though it is incremental as it builds on existing ILP frameworks.
The paper tackled the problem of requiring domain experts to also be Inductive Logic Programming experts to provide background knowledge, by developing a graphical user interface using Entity Relationship diagrams to construct modes automatically. The result showed that users could create effective background knowledge comparable to expert-encoded knowledge on five datasets.
One of the key advantages of Inductive Logic Programming systems is the ability of the domain experts to provide background knowledge as modes that allow for efficient search through the space of hypotheses. However, there is an inherent assumption that this expert should also be an ILP expert to provide effective modes. We relax this assumption by designing a graphical user interface that allows the domain expert to interact with the system using Entity Relationship diagrams. These interactions are used to construct modes for the learning system. We evaluate our algorithm on a probabilistic logic learning system where we demonstrate that the user is able to construct effective background knowledge on par with the expert-encoded knowledge on five data sets.
