In this paper, we present OPQL, an OPM-level provenance query language, that is directly defined over the Open Provenance Model (OPM). An OPQL query takes an OPM graph as input and produces an OPM graph as output.

nance storage strategies. In this paper, we present OPQL, an OPM-level provenance query language, that is directly defined over the Open Provenance Model (OPM). An OPQL query takes an OPM graph as input and produces an OPM graph as output. Therefore, OPQL queries are not tightly coupled to the underlying provenance storage strategies. Our main

2011年6月1日 · Our main contributions are: (i) we design an entity–relationship diagram for OPM and translate it into a relational database schema for the storage of provenance; (ii) we show that provenance reasoning defined in OPM (v1.1) can be sufficiently supported by OPMProv using recursive views and SQL queries alone without any additional reasoning engine.

2021年2月14日 · We demonstrate that OPQL outperforms prior VKB methods on two different KB reasoning tasks and, additionally, can be used as an external memory integrated into a language model (OPQL-LM) leading to improvements on two open-domain question answering tasks.

2013年11月1日 · In this paper, we designed the OPQL query language, including six types of graph patterns, a provenance graph algebra, and OPQL syntax and semantics, that enables querying of provenance at the graph level.
