2019 WWW Workshop | Knowledge Graph Technology and Applications


Knowledge Graph Technology and Applications

May 13-17, 2019/ San Francisco


Knowledge Graphs are graph structures that capture knowledge in the form of entities and the relationships between them, and optionally the provenance information. Along with Semantic Web standards such as RDF, OWL, and SPARQL, advances in Machine Learning, Deep Learning, Natural Language Processing, and Information Retrieval has led to automated construction of knowledge graphs such as DBpedia, YAGO, Wikidata, Google’s and LinkedIn’s  Knowledge Graph, Microsoft’s Satori, and Product Knowledge Graph from Amazon and eBay. Knowledge Graphs are used in several applications such as search, question answering, data integration, recommendation systems etc., across several domains such as healthcare, geosciences, manufacturing, aviation, power, oil and gas. There are several challenges related to knowledge graphs from the perspective of both the technology and its applications. This workshop aims to foster discussions along these perspectives.


Topics of interest include, but are not limited to the following. We especially encourage Knowledge Graph applications related to web search, conversational agents, recommendation systems, and in the Industrial domain such as manufacturing, aviation, power, oil and gas.

Construction and Maintenance of Knowledge Graphs

  • Handling noisy and incomplete data
  • Entity linking and resolution
  • Consistency checking when adding new knowledge
  • Collaborative maintenance of knowledge graphs
  • Provenance solutions for Knowledge Graphs
  • Handling uncertain content in Knowledge Graphs

Operations over Knowledge Graphs

  • Innovative methods for querying and interacting with knowledge graphs
  • Searching over knowledge graphs
  • Reasoning over knowledge graphs
  • Explaining knowledge graph contents

Mining Knowledge Graphs

  • Machine Learning and deep learning techniques for knowledge graph mining
  • Heterogeneous graph mining

Storage mechanisms for Knowledge Graphs

  • Graph databases, triple stores
  • New storage and indexing schemes for property graphs

Knowledge Graphs for NLP and IR

  • Web search, conversational agents, recommender systems, information access systems, and summary generation

Knowledge Graphs in the industrial domain

  • manufacturing, aviation, power, oil and gas, healthcare, banking, finance, and IoT

Industry use cases and best practices

  • manufacturing, aviation, power, oil and gas, healthcare, banking, finance, and IoT
  • Industry use cases and best practices




Authors can submit either full papers of 8 pages in length or short papers of 4 pages length in the ACM format (https://www.acm.org/publications/proceedings-template), with the “sigconf” option. Since we plan to follow single-blind review process, there is no need to anonymize the author list. Since the workshop papers will be included in the companion volume of The Web Conference proceedings, it is important to follow the suggested submission format. Submissions can be made using EasyChair at (https://easychair.org/conferences/?conf=kgtawww19). Authors of the accepted papers will be invited to give a short lightning talk of 5 minutes and/or present a poster at the workshop.

High quality submissions with substantial revisions will be invited to submit to Data Intelligence Journal (http://www.data-intelligence-journal.org/) and the Special Issue on “Linked Data and Knowledge Graph in Large Organisations” at the Information Journal (https://www.mdpi.com/journal/information/special_issues/Knowledge_Graphs).
