Negative life events, such as death of a family member, argument with a spouse and loss of a job, play an important role in triggering de- pressive episodes. Therefore, it is worth to de- velop psychiatric services that can automati- cally identify such events. In this paper, we propose the use of association language pat- terns, i.e., meaningful combinations of words (e.g., ), as features to classify sen- tences with negative life events into prede- fined categories (e.g., Family, Love, Work). The language patterns are discovered using a data mining algorithm, called association pat- tern mining, by incrementally associating fre- quently co-occurred words in the sentences annotated with negative life events. The dis- covered patterns are then combined with sin- gle wo...
