摘要：Aligning sentences belonging to comparable
monolingual corpora has been suggested
as a first step towards training
text rewriting algorithms, for tasks such
as summarization or paraphrasing. We
present here a new monolingual sentence
alignment algorithm, combining a
sentence-based TF*IDF score, turned into
a probability distribution using logistic regression,
with a global alignment dynamic
programming algorithm. Our approach
provides a simpler and more robust solution
achieving a substantial improvement
in accuracy over existing systems.
