  This demo paper presents the first tool to annotate the reuse of text,
images, and mathematical formulae in a document pair -- TEIMMA. Annotating
content reuse is particularly useful to develop plagiarism detection
algorithms. Real-world content reuse is often obfuscated, which makes it
challenging to identify such cases. TEIMMA allows entering the obfuscation type
to enable novel classifications for confirmed cases of plagiarism. It enables
recording different reuse types for text, images, and mathematical formulae in
HTML and supports users by visualizing the content reuse in a document pair
using similarity detection methods for text and math.
