A technique relates comparing content. A first set of content in a first document and a second set of content in a second document are normalized. The first set of content in the first document and the second set of content in the second document are tokenized. The first set of content having been tokenized and the second set of content having been tokenized are compared in order to find differences in the second set of content with respect to the first set of content. The differences are compiled in a changes map. The differences in the changes map are analyzed to determine types of the differences in the first set of content and the second set of content, and predefined differences are to be excluded. A report of the differences is generated, and the report delineates the types of the differences while excluding the predefined differences.
