Conventional sentence compression meth- ods employ a syntactic parser to compress a sentence without changing its mean- ing. However, the reference compres- sions made by humans do not always re- tain the syntactic structures of the original sentences. Moreover, for the goal of on- demand sentence compression, the time spent in the parsing stage is not negligi- ble. As an alternative to syntactic pars- ing, we propose a novel term weighting technique based on the positional infor- mation within the original sentence and a novel language model that combines statistics from the original sentence and a general corpus. Experiments that involve both human subjective evaluations and au- tomatic evaluations show that our method outperforms Hori’s method, a state-of-the- art conventional techniq...
