A Web Tool for the Semantic Integration of Heterogeneous and Complex Spreadsheet Tables

The acquisition and integration of data contained in spreadsheet tables is a complex task because they do not impose any regular structure on the organization of the data, or constraints on valid values.
Moreover, mistakes can occur due to the passage from a format to another one or misspelt words in the original sources. The automatic extraction of their content, interpretation and integration is thus a complex task. In this paper, we outline the characteristics of a semi-automatic, interactive tool conceived for creating a knowledge base by extracting semantic information from heterogeneous spreadsheets.
