## 3 Interconnecting Interdisciplinary Emotional Knowledge
### Keeping Track of Provenance Metadata  
To keep track of the source of knowledge, we explicitly add this information within the rule RDF dataset and LOV4 IoT RDF dataset as shown in Listing 1 by referring to the scientific publication in rdfs:comment and the link to the scientific paper with prov:hadPrimarySource from the W3C PROV-O ontology. For instance, prov:hadPrimarySource keeps track of the source by providing the URL of the scientific publication mentioning the rule or reasoning mechanism. ```

**Findable, Accesssible, Interoperable, Resuable (FAIR) principles**[14] encourage researchers to share their reproducible experiments by publishing online the resources such as ontologies, datasets, rules, etc. The set of ontology code available online can be automatically processed; if the ontology code is not available, the scientific publications describing the emotion ontologies are semi-automatically processed with Natural Language Processing (NLP) techniques to feed the emotion reasoning engine to build the recommender system.
