The second problem, which we call entity-level heterogeneity, has received much less attention, maybe because people thought this issue should be addressed only after the schema-level integration issue had been solved. , but for sure it does not compare to what has been done in the other area.

G. p53_HUMAN is the class of all the existing p53 proteins in human organisms) Generally speaking, we assign an ID to the individual the name refers to, and not to the class (so to the first case in the above list). This is motivated by the fact that some individuals do not have specific names, and therefore, taking language as a criterion to define what we want to refer to and what we do not, do not need to have global identifiers. g. the protein of type p53_HUMAN contained in a particular human organism).

The ENS architecture and serviceoriented use collection (or none if no entry exists), by applying matching techniques that are much related to the ones studied in de-duplication, but on un- or semi-structured data the representation of which is unknown.

The results – and more details that would go beyond the scope of this chapter – can be evaluated in the public deliverables of the OKKAM project5.
