Polu-nadgledani model tema NMF

Polu-nadgledani model tema temeljen na faktorizaciji nenegativnih matrica (NMF) proširuje nenadziranu NMF uključivanjem korisnički definiranih početnih riječi ili ograničenja oznaka kako bi se otkrivene teme usmjerile prema domenama relevantnim za struku. Faktorizira matricu dokumenata i riječi u interpretacijske nenegativne komponente, poštujući leksičke pretpostavke, što rezultira koherentnim, prilagođenim temama čak i iz skromnih korpusa.
