Reordering a coherent text that has been shuffled is a relatively easy task for humans. A successful algorithm doing such a reordering provides a lot of insight in how to do proper automatical multi-document summarisation and discourse generation. This research will address the development of an algorithm that attempts to automatically reorder sentences, answering the following question how good is a computer in reordering sentences compared to humans?.
1. INTRODUCTION
When one shuffles the sentences of an existing coherent text, a human is often able to easily reorder those sentences into proper discourse
machine do the same. Work by [odAea04] shows that having humans reorder texts can lead to ambiguities: often morethan one reordering leads to proper discourse The ability to successfully reorder sentences has several applications, amongst which discourse generation. A robust sentence-reordering-algorithm narrows the problem of generating proper discourse to simply forming (proper) sentences. Moreover, the ability to (re-) construct proper discourse from a set of sentences has a high potential in the field of (multi-) document summarisation; extracted sentences can be reformed into proper discourse. This research focuses on the reordering of sentences by means of a sorting algorithm; several modules provide hints on the order of individual sentences, which combined provide a partial ordering. This ordering guides the topological sorting of the sentences, which was defined [Bla04] as:

according to a partial order
Previous research [HMG95] has learned that it is possible to
determine the temporal structure of sentences, while there
exist several algorithms for doing automatic anaphor resolution.
This research attempts to use these (and other)
techniques in the reordering of sentences.
This research tries to expand this knowledge to the automatic
reordering of sentences by developing an algorithm,
which reorders sentences from a shuffled text. The resulting
algorithm is compared with humans before being evaluated.
.2. RESEARCH QUESTION
The research question is defined as: how good is a computer
in reordering sentences compared to humans? To
answer this question, various (existing) techniques are be
used, which leads to a sub-question: what techniques can
be used to determine sentence order?. If the prototype
developed in this research demonstrates a performance to
what may be expected from a human, it will be compared
to humans, answering a third question: how does automatically
reordered discourse compare to manually reordered
discourse?.
3. APPROACH
The answer to the question above depends entirely on the
quality of the software used to reorder sentences. The first
part of this research was thus dedicated to finding an existing
solution to the problem of reordering sentences. If
such a method was found, it would be applied and evaluated.
After some thorough searching on the web
it quickly appeared that such an algorithm did not exist yet.
The next step was to design an algorithm, which was to be
tested and compared with human reordering. Dutch was
chosen as language of the sentences to be ordered, since this
is the native (and thus the most intu¨ıtive) language of the
persons performing this research.
