CaRLA
The goal of CaRLA is two-fold: First, it aims to compute rules that allow
to derive conform representations of property values. As entities can have
several values for the same property, CaRLA also aims to detect a condition
under which two property values should be merged during the integration
process. In the following, we will assume that two source knowledge bases
are to be integrated to one. Note that our approach can be used for any num-
ber of source knowledge bases.
Formally, CaRLA addresses the problem of nding the required transfor-
mation rules by computing an equivalence relation
ε
between pairs of prop-
erty values (p
1
, p
2
), that is, such that
ε
(p

, p
2
) holds when p

and p

should be
mapped to the ...
