Knowledge Graphs: an integrated view of knowledge graphs

ByPaula Silva
May 2022. IMFD researchers Aidan Hogan y Claudio Gutierrezacademics from the Department of Computer Science, (DCC U. Chile), along with other experts from around the world, wrote the booktogether with other experts worldwide, wrote the book Knowledge Graphs, which seeks to provide an integrated view on knowledge graphs. knowledge graphsgraphs, both in the in both academia and industry.

Knowledge Graphs aims to give a general introduction to a new area of knowledge management in the digital age calledknowledge graphs. "This book delivers an integrated view on knowledge graphs, both in academia and industry. This is because there are various perspectives on what constitutes a knowledge graph, in what cases it is useful, etc.," explains Aidan Hogan.

Claudio Gutiérrez points out that knowledge graphs are the counterpart of databases in the area of knowledge. "They integrate decades of research on ways to store and make knowledge available in digital format. In that sense they distill the experience of semantic networks, knowledge bases, expert systems, and lately, machine learning techniques, to offer friendly systems to manage knowledge at all levels."

These systems are used in organizations to integrate, manage and disseminate knowledge on a large scale, explains Aidan Hogan: "In 2012, Google announced the use of the Google Knowledge Graph to enhance its Web search capabilities. Since then, several large companies - such as, for example, Airbnb, Amazon, eBay, Facebook, LinkedIn, Uber, etc. - have introduced their own knowledge graphs in the context of various applications related to search, recommendations, advertising, chatbots, and so on. Already since 2017 or 2018 there was a lot of interest, not only in the industry, but also in various academic communities."

Hogan indicates that this book is intended for any person and organization that has an interest in knowledge graphs, but in order to approach it, it is necessary to understand some general computer science concepts such as databases, machine learning, programming, etc. "This book is very relevant for teachers and advanced undergraduate or graduate students, for researchers in the same area or in related areas, for professionals who want to apply this technology in their organizations, etc."

It should be noted that Knowledge Graphs was born out of an international seminar in Dagstuhl, Germany, among a large group of researchers: Eva Blomqvist, Michael Cochez, Claudia d'Amato, Gerard de Melo, Sabrina Kirrane, José Emilio Labra Gayo, Roberto Navigli, Sebastian Neumaier, Axel-Cyrille Ngonga Ngomo, Axel Polleres, Sabbir M. Rashid, Anisa Rula, Lukas Schmelzeisen, Juan Sequeda, Steffen Staab, Antoine Zimmermann and DCC scholars Aidan Hogan and Claudio Gutiérrez.

Aidan Hogan emphasizes that one of the goals they have with this book is that it can be used in undergraduate and graduate courses. They also want it to be a reference book for researchers in the area and, finally, to integrate different communities interested in knowledge graphs. "The book puts a lot of emphasis on demonstrating how the area of knowledge graphs also incorporates topics from the database communities, logic, knowledge representation, network analysis, machine learning, the semantic web, etc. It is in a way a call to different communities to consider knowledge graphs as a unifying point of view in the area of knowledge management in the digital age," he concludes.
