| Abstract Scope |
The computer ontologies (“ashes from the fire of human thinking”) can be practically thought as the advanced databases. Their OWL standard was developed with the aim to mathematically guarantee, that the logical reasoning succeeds in finite time. In this work I benchmark the modern Python tools to work with several established nowadays OWL materials ontologies, such as EMMO and PMD. I also present our own in-house effort called MPDS. The highly inter-linked MPDS data graph consists of approximately 5M nodes and 150M edges. All the assertions were taken from the world’s published literature in materials science (about 0.5M publications since 1891), as curated by the Pauling Files project, see www.mpds.io. Also the MPDS data graph can be greatly expanded with our in-house ab initio simulations data, which will be produced high-throughput in the cloud fully automatically, controlled with the ontology reasoning engine. |
