matchmaker-sparql
A SPARQL-based matchmaker for matching public contracts to bidders. It expects data to be described by the Public Contracts Ontology. This matchmaker is a streamlined reimplementation of the previously developed matchmaker.
Usage
You can invoke the tool via Leiningen or compile it by running lein uberjar
and then executing the resulting JAR-file by Java. The only option you need to provide is a path to the configuration file:
lein run - --config config.edn
The configuration must be serialized using EDN.
A sample configuration file is here.
Evaluation results produced by the tool are written to a file resuls_{uuid}.edn
in the current directory.
Data preparation
The matchmaker expects Common Procurement Vocabulary (CPV) to be in the named graph <http://linked.opendata.cz/resource/concept-scheme/cpv-2008>
. Some matchmakers, such as those using query expansion, use inverse document frequencies (IDF) of CPV concepts. These IDFs can be produced by running SPARQL Update operations in /resources/data_preparation
.
