I'm trying to write a Multiple Document Summary (MDS) system as proposed by Chali et al. (2009), see attached. And after a lot of reading I've managed to wrap my head around a lot of the concepts.
However, one of the things I need to make is a component to parse sentences into syntactic trees. I've been looking around on Google for a while and I haven't found anything really useful. There are systems which draw the trees given a specific notation, but I have no way of creating that notation. A reference to a parser is given in the text (Charniak (1999)) however I can only read the abstract of this article not the full text.
If anybody could perhaps suggest an algorithm (or at least point me in the right direction) I would be really grateful.
Thanks in advance
