we present the annotation of a dataset that is used by our syntactic simplification method to identify places where rewriting rules have to be applied in order to produce simpler sentences.
The datasets are available in XML format as three independent files, each representing a different genre
Each file contains a list of sentences annotated using the following format:
<S ID="2"><SIGN ID="2" CLASS="SSEV">That</SIGN> is <SIGN ID="3" CLASS="HELP">,</SIGN> a high-fibre diet, fluid <SIGN ID="4" CLASS="CLN">,</SIGN> etc.</S>
The sentences are marked using the S tag, whilst the signs by the tag SIGN. The type of sign is encoded by the attribute CLASS. The sentences were annotated in isolation, so the files above do not contain coherent texts, but sequences of sentences extracted from different files.
To understand the difference between different classes and how the annotation process was carried out please consult the annotation guidelines. Specific questions about the annotation should be sent to Richard Evans. A demo of the sign tagger is available at http://rgcl.wlv.ac.uk/demos/SignTaggerWebDemo/
