In this paper, we present the DAGOBAH system which tackles the Tabular Data to Knowledge Graph Matching (TDKGM) challenge3 . DAGOBAH aims to semantically annotate tables with Wikidata and DBpedia entities, and more precisely performs cell and column annotation and relationship identification, via a pipeline starting from pre-processing to enriching an existing knowledge graph using the table information. This paper presents techniques for typing columns with fine-grained concepts while ensuring good coverage, and for valuing these types when disambiguating the cell content. This system obtains promising results in the CEA and CTA tasks on the challenge test datasets.
