Semantic Data Enrichment for Data Scientists

Tutorial website for the ESWC2024 tutorial on semantic data enrichment for data scientists.

TOPIC

This tutorial introduces the topic of semantic data enrichment, covering theoretical and practical considerations. In particular, the tutorial will provide an explanation of the role that semantics play in data enrichment for downstream AI-based applications, a review of the advantages and limitations of tools, methodologies, and techniques for semantic data enrichment available today, and a practical dive into the creation of data transformations for enriching the data.

OBJECTIVES

PROGRAM

The tutorial will be a half-day tutorial, requiring approximately three hours including presentations and a hands-on section. The draft schedule proposed for the tutorial is the following:

DATA ENRICHMENT FOR DATA SCIENCE 45 MIN

Topics: challenges; semantics technologies as key enablers; analytics with enriched data: use cases from industry-driven data science projects.

STATE-OF-THE-ART: SEMANTIC DATA ENRICHMENT FOR DATA SCIENCE 45 MIN

Topics: semantic table annotation tools and techniques; doing it with OpenRefine: lessons learned and limitations; data enrichment with batch pipelines: lessons learned and limitations; user-driven data enrichment at scale: the Grafterizer/ASIA approach; QMiner and data analytics on top of enriched data.

A TOOLKIT FOR USER-DRIVEN DATA ENRICHMENT AT SCALE ENDOWED WITH ROBUST ANALYTICAL MODELING 30 MIN

Topics: SemTUI fully modular framework: extending, annotating and enriching data; Expert AI tools: category classification on top of enriched data.

HANDS-ON SESSION: PROCUREMENT DATA ENRICHMENT WITH WIKIDATA IDS 60 MIN

Environment set up; design of the data transformation workflows with SemTUI; batch execution of the transformations on a larger data set; design of larger data set transformation workflows with TAO.
