Object Matching / Entity Resolution

Object Matching (Entity resolution) is a critical data integration task and aims at identifying semantically corresponding objects (records, instances) in one or several data sources. A typical example is the redundant and heterogeneous representation of customers in different enterprise databases. Finding corresponding customer representations is a key task, e.g., for customer relationship management or master data management, in general. On the web, finding matching ovjects is typically even more challenging due to the higher degrees of heterogenity (less structured data with many text attributes, more sources, more data quality problems etc.).
