Abstract

Ovaj rad uspoređuje neke pristupe klasifikaciji digitalnih razgovora. Na početku su dani osnovni matematički pojmovi potrebni za razumijevanje tema obrađenih u radu. Nakon toga, objašnjavamo prilagodbu teksta matematičkim modelima te predstavljamo modele za klasifikaciju. Zatim tražimo ključne riječi i fraze u tekstu faktorom lokalnih izuzetaka i pokušavamo efikasnije prilagoditi težine pojmovima u dokumentu. Konačno, analiziramo dobivene rezultate.

Abstract (english)

In this work, we present and compare some approaches to classifying text, particularly digital conversations. The first part is dedicated to explaining the basic mathematical concepts necessary for the understanding of the topics explored in the paper. Next, we explain the text parsing techniques and introduce 3 classification models. We search for key words and phrases throughout the text using local outlier factor and we aim to assign weights more efficiently to the terms in the document. Finally, we analyze the results obtained.
