Knowledge Graphs in Manufacturing and Production: A Systematic Literature Review
Knowledge graphs in manufacturing and production aim to make production lines
more efficient and flexible with higher quality output. This makes knowledge
graphs attractive for companies to reach Industry 4.0 goals. However, existing
research in the field is quite preliminary, and more research effort on
analyzing how knowledge graphs can be applied in the field of manufacturing and
production is needed. Therefore, we have conducted a systematic literature
review as an attempt to characterize the state-of-the-art in this field, i.e.,
by identifying exiting research and by identifying gaps and opportunities for
further research. To do that, we have focused on finding the primary studies in
the existing literature, which were classified and analyzed according to four
criteria: bibliometric key facts, research type facets, knowledge graph
characteristics, and application scenarios. Besides, an evaluation of the
primary studies has also been carried out to gain deeper insights in terms of
methodology, empirical evidence, and relevance. As a result, we can offer a
complete picture of the domain, which includes such interesting aspects as the
fact that knowledge fusion is currently the main use case for knowledge graphs,
that empirical research and industrial application are still missing to a large
extent, that graph embeddings are not fully exploited, and that technical
literature is fast-growing but seems to be still far from its peak
Domain-specific Knowledge Graphs: A survey
Knowledge Graphs (KGs) have made a qualitative leap and effected a real
revolution in knowledge representation. This is leveraged by the underlying
structure of the KG which underpins a better comprehension, reasoning and
interpretation of knowledge for both human and machine. Therefore, KGs continue
to be used as the main means of tackling a plethora of real-life problems in
various domains. However, there is no consensus in regard to a plausible and
inclusive definition of a domain-specific KG. Further, in conjunction with
several limitations and deficiencies, various domain-specific KG construction
approaches are far from perfect. This survey is the first to offer a
comprehensive definition of a domain-specific KG. Also, the paper presents a
thorough review of the state-of-the-art approaches drawn from academic works
relevant to seven domains of knowledge. An examination of current approaches
reveals a range of limitations and deficiencies. At the same time, uncharted
territories on the research map are highlighted to tackle extant issues in the
literature and point to directions for future research
