Abstract: A method for comparing and analyzing digital documents includes searching for unambiguous roots in both documents. These roots are unique units that occur in both documents. The roots can be individual words, word groups or other unambiguous textual formatting functions. There is then a search for identical roots in the other document (Root1 from Content1, and Root2 from Content2, with Root1=Root2). If a pair is found, the area around these roots is compared until there is no longer any agreement. During the area search, both preceding words and subsequent words are analyzed. The areas that are found in this way, Area1 around Root1 and Area2 around Root2, are stored in lists, List1 and List2, allocated to Doc1 and Doc2. This procedure is repeated until no roots can be found any longer. The result is either a remaining area that has no overlaps, or complete identity of the documents.

Abstract: The invention relates to a method for comparing and analysing digital documents. The present invention is founded on the basic principle of searching for unambiguous roots in both documents. These roots are units which occur in both documents and in each case are unique. These roots can be individual words, word groups or other unambiguous textual formatting functions. There is then a search for identical roots in the respective other document (Root1 from Content1, and Root2 from Content2, with Root1=Root2). If a pair has been found, the area around these roots is compared until there is no longer any agreement. During the area search, both the preceding words and the subsequent words are analysed. The areas which are found in this way, Area1 around Root1 and Area2 around Root2, are stored in lists, List1 and List2, which are allocated to Doc1 and Doc2. This procedure is repeated until such time as no roots can be found any longer.
