Abstract

Provjerom istinitosti činjenica iz teksta želi se validirati točnost određene tekstne tvrdnje na temelju čistog teksta i neke baze znanja, u slučaju ovog rada, Wikipedije. Korištene su metode strojnog i dubokog učenja. Korišten je okvir zadatka s radionice FEVER. Isprobani su referentni model s radionice FEVER i alternativne komponente za odabir dokumenata i rečenica. Kao najbolji model po FEVER-metrici na jednostavnijim primjerima pokazao se referentni s izmijenjenom komponentom za odabir dokumenata (0.31) dok se na složenijim primjerima kao najbolji pokazao referentni model (0.27).

Abstract (english)

Fact Checking from natural language aims to validate the correctness of the claim using raw text of that claim and a given knowledge base, in our case Wikipedia articles. We used machine learning and deep learning. We also used FEVER Workshop task as a problem framework. We tried FEVER baseline model and modified it with alternative document and sentence selection components. On simpler examples document selection modified model gave the best results by FEVER metric (0.31) and on more complex examples no model outperformed the baseline (0.27).
