Declarative Sequential Pattern Mining of Care Pathways

Participants : Thomas Guyet, André Happe [Brest University Hospital/REPERES] , Yann Dauxais.

Sequential pattern mining algorithms are widely used to explore care pathways database, but they generate a deluge of patterns, mostly redundant or non-informative. Clinicians need tools to express complex mining queries in order to generate less but more significant patterns. These algorithms are not versatile enough to answer complex clinician queries. This work [12] proposes to apply a declarative pattern mining approach based on the Answer Set Programming paradigm. It is exemplified by a pharmaco-epidemiological study investigating the possible association between hospitalization for seizure and antiepileptic drug switch from a French medico-administrative database.
