“Modern data lakes are heterogeneous in the vocabulary that is used to describe data. … How can we determine if a data value occurring more than once in the lake has different meanings and is therefore a homograph? While word and entity disambiguation have been well studied, … we show that data lakes provide a new opportunity for disambiguation of data values. … We introduce DomainNet, which efficiently represents this network, and investigate to what extent it can be used to disambiguate values without requiring any supervision.”
