|Abstract=Important questions about the scientific community, e.g., what authors
are the experts in a certain field, or are actively engaged in international collaborations, can be answered using publicly available datasets. However, data required to answer such questions is often scattered over multiple isolated datasets.
Recently, the Knowledge Graph (KG) concept has been identified as a means
for interweaving heterogeneous datasets and enhancing answer completeness and
soundness. We present a pipeline for creating high quality knowledge graphs that
comprise data collected from multiple isolated structured datasets. As proof of
concept, we illustrate the different steps in the construction of a knowledge graph
in the domain of scholarly communication metadata (SCM-KG). Particularly, we
demonstrate the benefits of exploiting semantic web technology to reconcile data
about authors, papers, and conferences. We conducted an experimental study on
an SCM-KG that merges scientific research metadata from the DBLP bibliographic source and the Microsoft Academic Graph. The observed results provide
evidence that queries are processed more effectively on top of the SCM-KG than
over the isolated datasets, while execution time is not negatively affected.
|Conclusion=In this paper, we presented the concept of Scholarly Communication Metadata Knowledge Graph (SCM-KG), which integrates heterogeneous, distributed schemas, data and
metadata from a variety of scholarly communication data sources. As a proof-of-concept,
we developed an SCM-KG pipeline to create a knowledge graph by integrating data collected from heterogeneous data sources. We showed the capability of parallelization in
rule-based data mappings, and we also presented how semantic similarity measures are
applied to determine the relatedness of concepts in two resources in terms of the relatedness of their RDF interlinking structure. Results of the empirical evaluation suggest
that the integration approach pursued by the SCM-KG pipeline is able to effectively
integrate pieces of information spread across different data sources. The experiments
suggest that the rule based mapping together with semantic structure based instance
matching technique implemented in the SCM-KG pipeline integrates data in a knowledge graph with high accuracy. Although our initial use case addresses the scientific
metadata domain, we generated billions of triples with high accuracy in mapping and
linking, and we regard it capable at an industrial scale and in use cases demanding high
precision.
|Future work=In the context of the OSCOSS project on Opening Scholarly Communication
in the Social Sciences, the SCM-KG approach will be used for providing authors with
precise and complete lists of references during the article writing process.
