Graph integration of structured, semistructured and unstructured data for data journalism

作者：

Highlights：

• We define novel integration graphs and we construct them from arbitrary datasets

• We build the graphs leveraging data integration, information extraction, and data management

• We propose a novel algorithm finding matches across heterogeneous data sources

• We implement our approach on text, CSV, JSON, XML, RDF, PDF and relational datasets

• We evaluate our approach using a set of use cases with real journalistic datasets
