Description

In recent years, knowledge graphs (KGs) have been increasingly used by both academia and industry to incorporate semantics into various intelligent applications. However, the creation of these knowledge graphs are mainly done manually with the help of domain experts and/or by using structured knowledge sources such as Wikipedia. Kno.e.sis Knowledge Graph team works on different aspects to improve creation and consumption of knowledge graphs as given below:

• Contextualized knowledge graphs
• Bootstrap domain-specific knowledge graphs by leveraging existing knowledge sources
• Summarization of the knowledge graphs
• Leveraging knowledge graphs to improve NLP applications
• Dynamically evolve knowledge graphs for real-time events such as twitter campaigns
• Question answering on knowledge graphs
• Ontology quality and best practices
• Ontology methodology to reuse ontologies
• Ontology alignment
• Knowledge extraction from ontologies to reuse the domain knowledge already designed in previous domains.
• Semantic interoperability with a focus on ontologies

Knowledge Graphs (KG) for Applications

KG for Healthcare

Leaders: Dr. Saeedeh Shekarpour, Dr. Amelie Gyrard

KG for Internet of Things (IoT)

Leader: Dr. Amelie Gyrard

Ontology Catalogue for Internet of Things with LOV4IoT

Linked Open Vocabularies for Internet of Things (LOV4IoT) references numerous ontology-based IoT projects:
- Almost 500 ontology-based projects for IoT, smart cities, etc.
- Almost 20 domains relevant to IoT referenced such as building, smart grid, smart agriculture, smart transportation, healthcare, etc.
- We provide the LOV4IoT ontology catalogue as an HTML view.
- We also provide the LOV4IoT RDF dataset.
LOV4IoT is an extension of the LOV (linked Open Vocabularies) catalogue.
