Semantic Data Dictionary Generator (SDD-Gen)

Semantic tabular interpretation algorithm

The SDD-Gen is an ontological-level alignment algorithm that aligns tabular data to ontological terms for knowledge graph generation. It leverages context information from data dictionaries to generate suggestions for tabular alignments using semantic data dictionaries. It can operate on complex tables with multiple subject columns and few named entities.
