How to build a knowledge graph

Time: 
Monday, September 9, 2019 - 13:30 to 17:30

Chaired by: Elias K ̈arle, Umutcan S ̧im ̧sek, Dieter Fensel (all Semantic Technology Institute Innsbruck)

Building and hosting a Knowledge Graph requires some effort and a lot of experience in semantic technologies. Turning this Knowledge Graph into a useful resource for problem solving requires even more effort. The overall goal of building a Knowledge Graph is to provide cost-sensitive methods to host knowledge, improve the quality of large Knowledge Graphs and ensuring their usefulness for envisaged applications: “There are two main goals of Knowledge Graph refinement: (a) adding missing knowledge to the graph, i.e., completion, and (b) identifying wrong information in the graph, i.e. error detection.” [5] This tutorial is targeting the process from knowledge creation over knowledge hosting, knowledge curation to knowledge deployment - applied to a Knowledge Graph using schema.org as an ontology.

Goal

Introducing methods, tools and best practices for knowledge creation, hosting, curation (i.e. assessment, correction and enrichment) and deployment. Building a Knowledge Graph based on manually and semi-automatically created schema.org annotations.

Tentative Structure of the Tutorial
  1. What is a Knowledge Graph: Introduction to Knowledge Graphs, a simple formalism, examples of open and proprietary Knowledge Graphs
  2. Manual and semi-automatic creation of knowledge: Introduction to schema.org, domain specific patterns for schema.or annotations[8], tools and methods for knowledge creation (e.g. RML [1, 7]), demonstrations with selected tools
  3. Knowledge hosting: graph databases vs. document databases, provenance tracking
  4. Knowledge curation: Methods and tools from the literature for assessment, correction and enrichment of Knowledge Graphs
  5. Knowledge deployment: Publication and consumption of Knowledge Graphs through, for example, intelligent personal assistants, chatbots...
Organizers

The organizers have strong background in semantic technologies due to their active research in that field (see Section 2). Besides that, the organizers have a lot of co-operations with industry partners and are organizing events for a very long time (Dieter Fensel is for example co-founder of ESWC, ISWC and TourismFastForward. Elias K ̈arle and Umutcan Simsek were organizing several tutorials and workshops for and with industry partners).
