[Solved] How to use Alignment API to generate a Alignment Format file?

First question: I guess that the “mentioned method” is the one in tutorial1. It is not the appropriate one since you have to write a program to output the alignment format and this is a command line interface tutorial. In this case, you’d better look at http://alignapi.gforge.inria.fr/tutorial/tutorial2/index.html

Then, there are basically two ways to do:

The advised one (for several reasons and for participating to OAEI) is to follow these tutorials, to create an empty alignment in it, to create the correspondences from the results of your SPARQL query and to render it. Everything is covered by the tutorials but the part concerning your SPARQL queries. This assumes that you are programming in Java.

The non-advised solution (primarily non advised because you will have to debug your own renderer), is to write, in any programming language that you want a program that output the format (which corresponds to what you cite).

Think about it: how would you expect that the Alignment API knows the results of your SPARQL query? If you come up with a nice solution, contact the API developers, they may integrate it and others could benefit.

Second question: I cannot do better than what is above.

Third question: too general. Read the OAEI results (http://oaei.ontologymatching.org) and look at the code of others.

Good luck!
