Hi Oleg, You may want to look into learning about UIMA and UIMAFIT.
Once you are somewhat comfortable with these frameworks, take a look at the package: ctakes/ctakes-relation-extractor/src/main/java/org/apache/ctakes/relationextractor/pipelines/ There are several pipelines that may work for you (e.g. take a look at RelationExtractorPipeline.java). Many of them should generate XMI files which contain the relation annotations you are looking for. Once you have generated the XMI files, you can parse them using UIMAFIT. E.g. take a look at RelationAnnotationViewer.java which you should use as an example. Hope this helps!
