Ontology Based Data Conversion from Spreadsheet to OWL

At present, there are a large number of data stored in spreadsheets. With the development of semantic web and ontology technology, importing the spreadsheet data into semantic web is helpful for knowledge sharing and acquisition. Existing conversion methods always convert the spreadsheet data into RDF, which cannot be integrated into constructed ontology base. This paper proposed an open architecture called Anyt2OWL for the conversion from various traditional formats to OWL based on ontology schema. Following Any2OWL, the method of converting spreadsheet to OWL which can be imported into ontology base is implemented. In addition, a declarative language is designed to express the mappings between spreadsheet and ontology.
