The vast amounts of ontologically unstructured information on the Web,
including HTML, XML and JSON documents, natural language documents,
tweets, blogs, markups, and even structured documents like CSV tables,
all contain useful knowledge that can present a tremendous advantage to
the Artificial Intelligence community if extracted robustly, efficiently
and semi-automatically as knowledge graphs. Domain-specific Knowledge
Graph Construction (KGC) is an active research area that has recently
witnessed impressive advances due to machine learning techniques like
deep neural networks and word embeddings. This book will synthesize
Knowledge Graph Construction over Web Data in an engaging and accessible
manner.
The book describes a timely topic for both early -and mid-career
researchers. Every year, more papers continue to be published on
knowledge graph construction, especially for difficult Web domains. This
book serves as a useful reference, as well as an accessible but
rigorous overview of this body of work. The book presents
interdisciplinary connections when possible to engage researchers
looking for new ideas or synergies. The book also appeals to
practitioners in industry and data scientists since it has chapters on
both data collection, as well as a chapter on querying and off-the-shelf
implementations.
