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 for Contextualization

  • Biomedical Vocabulary Alignment at Scale in the UMLS Metathesaurus The Unified Medical Language System (UMLS) 1 is a rich repository of biomedical vocabularies developed by the US National Library of Medicine. It is an effort to overcome challenges to the effective retrieval of machine-readable information. The enormous knowledge accumulated over 30 years of manual curation coupled with the advent of statistical and symbolic AI research 2 open up opportunities to improve the UMLS Metathesaurus construction and maintenance process. Specifically by developing novel approaches to aid and complement the efforts of the UMLS human editors in the insertion and updates of new biomedical vocabularies in the existing UMLS Metathesaurus for future releases.

Knowledge Graphs for Personalization

  • Personalized Health Knowledge Graph Our current health applications do not adequately take into account contextual and personalized knowledge about patients. In order to design "Personalized Coach for Healthcare" applications to manage chronic diseases, there is a need to create a Personalized Healthcare Knowledge Graph (PHKG) that takes into consideration a patient's health condition (personalized knowledge) and enriches that with contextualized knowledge from environmental sensors and Web of Data (e.g., symptoms and treatments for diseases).

Knowledge Graphs for Autonomous Driving

  • Knowledge-infused Learning for Entity Prediction in Driving Scenes Scene understanding is a key technical challenge within the autonomous driving domain. It requires a deep semantic understanding of the entities and relations found within complex physical and social environments that is both accurate and complete. In practice, this can be accomplished by representing entities in a scene and their relations as a knowledge graph (KG). This scene knowledge graph may then be utilized for the task of entity prediction, leading to improved scene understanding.

Knowledge graph for Drug Abuse

  • Knowledge graph for Drug AbuseDAO provides a powerful framework and a useful resource that can be expanded and adapted to a wide range of substance use and mental health domains to help advance big data analytics of web-based data for substance use epidemiology research.

Knowledge Graphs (KG) Applications


The AIISC EMPWR: Knowledge Graph Development Platform effort involves the development of a comprehensive tool and platform for KG development with the following aims

1. Develop a KG development platform capable of instantiating KGs in any domains from structured, semi-structured, and unstructured data.

2. Improve & address the limitations of existing KG platforms

3. Constructs a Knowledge Graph (based on a combination of)

    • Enrich an existing Knowledge Graph (Top-down declarative)
    • Construct a Knowledge Graph out of given entities (Bottom-up data driven)


Scooner Scooner is a knowledge-based literature search and exploration system where recently published results are computationally extracted and used a background KB to guide the search process. The key here is that the knowledge base that guides the search is extracted from the same universe of literature that is being explored.

Human Performance and Cognition Ontology

HPCO The human performance and cognition ontology (HPCO) project aims to achieve the following two major objectives

  1. Build a knowledge base using semi-automatic domain hierarchy construction and relationship extraction from PubMed citations;
  2. Build a tool to browse and explore scientific literature with the help of the knowledge base created in 1.

The project involves extending our work in focused knowledge (entity-relationship) extraction from scientific literature, automatic taxonomy extraction from selected community authored content (eg Wikipedia), and semi-automatic ontology development with limited expert guidance.
