This paper presents J-RAn (Java Requirement Analyzer), a tool that implements a novel Content Analysis technique to support the verification of consistency and completeness of a Software Requirement Specification. This technique exploits the extraction, from a requirement document, of the interactions between the entities described in the document as Subject-Action-Object (SAO) triples (obtainable using a suitable syntactic parser). SAO triples represent a concept in its most synthesizing form.
