2 Managing Semantic Data in Research Data Services Trend: Publish research data along with paper Digital library of research data How do we manage this data? E. g. , our research requires: Several Tera Bytes of data 5 billion data elements so far (c) Dr. Kavi Mahesh; Do not copy or distribute 2/23/2021

3 Inverting the Publication Model Past: Description of research results in English Show samples of data “Results, Discussion, Conclusion” framework Present: Publish article and entire dataset No links between article and data (c) Dr. Kavi Mahesh; Do not copy or distribute 2/23/2021

4 The Inverted Publication Model Future: Inverted model: Publish self-contained data Publish data analytics Annotate the data with English descriptions where needed Rich linkage between datasets Web of linked data… (c) Dr. Kavi Mahesh; Do not copy or distribute 2/23/2021

8 Self-Contained Dataset Requirements: Have a proper and consistent structure; Define each element both syntactically and semantically; Specify all the semantic constraints on permissible data values, their types and cardinalities; and Specify data provenance, etc. (c) Dr. Kavi Mahesh; Do not copy or distribute 2/23/2021

9 Ontology of Research Data In other words, an ontology of research data Where is the “Dublin Core” of research data? E. g. , CERIF (c) Dr. Kavi Mahesh; Do not copy or distribute 2/23/2021

10 Why Semantic Data Management? Epistemology of science: Verifying research results Making sense of someone else’s data Documenting the usage scenario of data (c) Dr. Kavi Mahesh; Do not copy or distribute 2/23/2021

13 Data on the Web: 5 -Star Rating System * Data on the Web: ** Machine-Readable Data: E. g. , data published as a spreadsheet *** Non-Proprietary Format: E. g. , data published as a CSV file E. g. , data published as a set of scanned images **** RDF Data: E. g. , a drug database published in RDF ***** Linked RDF Data: Links to other people’s data are included. E. g. , the Dbpedia dataset extracted from wikipedia (c) Dr. Kavi Mahesh; Do not copy or distribute 2/23/2021

14 Linked Open Data: Principles Use URIs as names of things: E. g, mention author by URI, not just name. Use HTTP URIs so that people can look up those names. When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL). Include links to other URIs, so people can discover more things. Sir Tim Berners-Lee (c) Dr. Kavi Mahesh; Do not copy or distribute 2/23/2021

15 Linked Open Research Data Services Requirements: Uniquely identify all entities used in datasets such as experiments, specimens, locations, organizations, etc. ; Interlink parts of datasets with precise parts of an article in both directions; Classify datasets using a suitable universal classification scheme; Cite other datasets, i. e. , refer to them through links; Manage multiple versions and revisions of datasets; and Incorporate a suitable controlled vocabulary or ontology.

17 An Ontology for Research Data (c) Dr. Kavi Mahesh; Do not copy or distribute 2/23/2021

18 Concluding Remarks Publishing and citing research data will be a common practice Digital libraries need to manage research data Data needs to be self-contained, therefore semantic Linked open data is promising We need a proper ontology of research data Keyword search may be good enough for documents, but not for datasets (c) Dr. Kavi Mahesh; Do not copy or distribute 2/23/2021
