Sentiment analysis Sentimenta analīze Artificial neural networks Datorzinātne Mākslīgie neironu tīkli

description

Šī darba mērķis ir izveidot sentimenta analīzes risinājumu, kuru paredzēts izmantot informācijas ieguves sistēmas koncepta izstrādē. Sentimenta analīze tiks veikta sociālo tīklu ziņām. Darba izstrādes sākumā tika veikta esošo sentimenta analīzes risinājumu izpēte un to rezultātu salīdzināšana. Tālāk tika veikta publiski pieejamo treniņdatu korpusu ievākšana. Papildus iegūtajiem datiem, tika izveidots latviešu valodai paredzēts sentimenta analīzes treniņdatu korpuss. Korpusa izveidošanas procesā tika veikta informācijas ieguves sistēmas koncepta izveide. Pēc nepieciešamo treniņdatu savākšanas, tika veikta ilgās īstermiņa atmiņas rekurentā neirona tīkla izveidošana un optimizēšana. Darba rezultātā tika iegūts latviešu valodas Twitter ziņu sentimenta korpuss un uz mākslīgajiem neironu tīkliem bāzēts sentimenta analīzes risinājums, kas sasniedza 82,37% precizitāti, 81,86% pārklājumu un 81,86% F1 mēru.
