Apstrakt
U ovom radu predstavljeno je jedno rešenje za izdvajanje delova teksta iz korisničkih recenzija koji predstavljaju nosilac sentimenta za određeno jelo i klasifikaciju tih delova teksta prema osećanju koje je u njima iskazano na pozitivno, negativno ili neutralno korišćenjem metoda mašinskog učenja. Segmenti teksta recenzija koji sadrže pominjanje hrane su formirani na osnovu leksičkih veza između reči i na njih su primenjene određene tehnike pretprocesiranja. Potom je izvršena sentiment analiza upotrebom nekoliko modela mašinskog učenja. Svi podaci su prikupljeni sa sajta Donesi.com i ručno anotirani. Korišćeni modeli su evaluirani.
