| Abstract | |
The flexibility provided by spreadsheets allows their customization following mental models of their authors and makes them popular data management systems. Gradually there is a growing need of integrating and join data from different spreadsheets and, to enable machines assistance in this process, the challenge is how to automatically interpret their implicit schema, which is addressed to human interpretation. In this sense, some related works propose mapping spreadsheets contents to open interoperability standards, mainly Semantic Web standards. The main limitation of such proposals is the assumption that it is possible to recognize and make explicit the schema and the semantics of spreadsheets automatically apart from their domain. This work differs by assuming the essential role of the context and the domain in which the spreadsheet was conceived to delineate shared practices of the community, which establishes building patterns to be automatically recognized by our system, in data extraction process and schema recognition. Our proposal involves a strategy to characterize building patterns related to conceptual models of authors in spreadsheets building process, which results from an extensive research of practices shared among authors of spreadsheets in the Biology usage domain. In this document we present a result of a practical experiment involving such a system, in which we integrated data from hundreds of spreadsheets available on the Web. This integration was possible due to a unique ability of our approach of recognizing the spreadsheet nature analyzed inside its creation context (AU) | |
