| Abstract(in English) | We explore the use of (possibly non-contiguous) word sequence patterns as the features in the task of automatically classifying sentences in the MEDLINE abstracts. In this task, the categories to which the sentences are classified are determined not by their topics, but in accordance with the typical subsections in the abstracts; i.e., Background, Objectives, Conclusions, etc. The bag-of-words representation commonly used in text categorization is inadequate for this particular task, as the turns of phrase or expression characterize the categories better than the individual content words. An improvement of 3 to 11 points in terms of F-measure was observed when the sequential patterns mined with the PrefixSpan algorithm were used in addition to the bag-of-word features. |
