uComp Protégé Human Computation Plugin

A GWAP Plugin for the validation of ontologies for the Protégé Ontology Editor. The plugin facilitates the integration of typical crowdsourcing tasks into ontology engineering from within the Protégé ontology editor. The goal is a reduction of the cost of validation, as well as scalability and reductions in working time.

MINERful is a Java-based tool for the automated discovery of declarative process models, out of event logs recorded by business process management systems. It is known to be the fastest declarative process miner currently existing in the literature. MINERful comes bundled with three additional modules: a generator of synthetic event logs of arbitrary size, given a process model in input; a synthetic injector of noise in synthetic event logs; a simplification engine, aimed at reducing the size of process models by removing irrelevant information.

Open Data Portal Watch

The Open Data Portal Watch framework is a monitoring and quality assessment framework for Open Data Portals. Currently, we are monitoring 260 Open Data portals in a weekly basis and assess their metadata quality along 5 dimensions and 19 metrics.
