Efficient Explainable Learning on Knowledge Graphs

Deliverables

First version of KG representation approaches

This deliverable will describe the 1st version of the knowledge graph representation approaches developed in ENEXA. Implementation details and an evaluation of each approach against the existing state of the art will be presented.

First version of the explainable ML algorithms

This deliverable will describe the first version of the efficiency and explainability algorithms. Moreover, baseline implementations provided by ENEXA will be presented.

Preliminary version of the platform

Software release of the ENEXA platform after the first development phase including preliminary versions of the code, documentation and test scenarios.

Use case definitions

Report refining the identified requirements by stakeholders in the three use cases as well as recommendations on visualizations / design, work process support and use cases.

Requirement specification

This deliverable will include the initial set of requirements identified from the users. This serves as a direct input for WP3 and WP4 in which the ENEXA approaches will be developed. It will also be used to evaluate the platform after the first development phase and plan development steps for the second development.
