Claim One:
1. A process for supporting computer infrastructure, said process comprising providing at least one support service for at least one of creating, integrating, hosting, maintaining, and deploying computer-readable code in a computing system, wherein the code in combination with the computing system is capable of evaluating cross-domain clusterability upon a target domain and a source domain, said evaluating comprising: receiving the source domain and the target domain, wherein the source domain comprises at least one source data item and the target domain comprises at least one target data item; calculating target clusterability as an average of a respective clusterability of said at least one target data item such that the target clusterability quantifies how clusterable the target domain is, wherein the respective clusterability of a target data item of said at least one target data item quantifies how unambiguously the target data item can be assigned to a respective true target centroid associated with the target data item; calculating target-side matchability as an average of a respective matchability of each target centroid of the target domain to source centroids of the source domain such that the target-side matchability quantifies how well target centroids of the target domain are aligned with the source centroids; calculating source-side matchability as an average of a respective matchability of each source centroid of said source centroids to the target centroids such that the source-side matchability quantifies how well the source centroids are aligned with the target centroids; calculating source-target pair matchability as an average of the target-side matchability and the source-side matchability; calculating cross-domain clusterability between the target domain and the source domain as a linear combination of the calculated target clusterability and the calculated source-target pair matchability by use of a trade-off parameter that indicates relative contribution of the target clusterability and the source-target pair matchability to the cross-domain clusterability; and transferring the calculated cross-domain clusterability to a device selected from an output device of the computer system, a storage device of the computer system, a remote computer system coupled to the computer system, and a combination thereof, wherein the target clusterability Cab(T| C t ) is Cab(T| C t )=Σ (t i εT) Cab(t i | C t )/|T|, wherein the respective clusterability Cab(t i | C t ) of an i-th target data item t i of said at least one target data item of the target domain T is Cab(t i | C t )=sim(t i , C * t (t i ))−max {C j t =C * t (t i )} sim(t i , C j t ), for integer i being greater than or equal to 1 and smaller than or equal to k, wherein a first term sim(t i , C j t ) is a respective similarity of the i-th target data item t i to a respective true target centroid of the i-th target data item t i , denoted as C * t (t i ), and wherein a second term max {C j t =C * t (t i )} sim(t i , C j t ) is a largest value among all respective similarities of each target data item t i to a respective target centroid C j t that is not the respective true target centroid C * t (t i ).
