Experiment Results

Paths Alignment

In the following table are presented the precision and the recall for each service (averaged over the APIs that provide the service). We ran experiments for both alignment strategies: the overlapping and the subsumption strategy. For the overlapping strategy, we show also the results of the method containing data cycles (WithCycles). For the subsumption, we checked whether the results of the KB path are subsumed by the results of the XML path (KB → W S), and vice-versa (W S → KB). Click on the table for more details.

Path Alignment



The results of our path alignment algorithm and the goldset, for each Web service are in the folder:

Path Alignment (Overlapping) - Dropbox Folder.


Path Alignment (Association Rule Mining ) - Dropbox Folder.


Classes and Relations Alignment

We tested the class and relation alignment that keeps duplicates (With dup.), and the alignment that removes duplicates (DORIS). Our evaluation shows that duplicates can be safely removed: the precision in the relations increases while the recall is unchanged in a majority of cases and relations.

Classes-Relations Alignment



The results of our class and relation alignment algorithm and the goldset, for each Web service are in the folder:

Class and Relation Alignment - Dropbox Folder.


Views and Transformation Functions

The xslt code is produced by using the class & relation alignment result of each function are in the following folder:

XSLT - Dropbox Folder.

You can test the result on the online XSLT Editor of w3schools here by using the code that we produce and a call result of a Web service.
