- paper-17 abstract "Web tables comprise a rich source of factual information.However, without semantic annotation of the tables’ content the infor-mation is not usable for automatic integration and search. We propose amethodology to annotate table headers with semantic type informationbased on the content of column’s cells. In our experiments on 50 tableswe achieved an F1 value of 0.55, where the accuracy greatly varies de-pending on the used ontology. Regarding computational complexity wefound out that 94% of the maximal F1 score on average 20 cells (37%)need to be considered. Results suggest that the choice of the ontologyplays a more crucial role for type inference than the number of cells used.".
