Digitālo tekstu sentimenta analīze

Abstract

Zinātniskajā darbā tiek pētīta sentimenta analīze, tās pielietojumi, algoritmi un to efektivitāte. Darba gaitā tika izstrādāts sentimenta analīzes dzinis latviešu valodai, kas nosaka teksta semantisko orientāciju, izmantojot Turnija algoritmu. Uz izstrādātā dziņa bāzes tika uzprojektēta un izveidota sistēma, kas nosaka dienas noskaņojumu Latvijā, analizējot viedokļus, ko cilvēki izsaka dažādos interneta resursos.
