The ease by which researchers access information from the Web without proper documentation of sources breeds plagiarism. The study determined the efficacy of technology-based quality assurance of international researches adopted by the Asian Scientific Journal Publications of Liceo de Cagayan University. Using a descriptive research design involving 150 specimen scientific articles both local (n=128) and foreign (n=22), the study examined the state of readability, originality and plagiarism before and after the peer review and editorial process and interventions. Results show that the amount of plagiarism decreased significantly, indicating improvement in the originality of articles. The academic readability measured by the Gunning Fog Index and Flesch Reading Ease also improved significantly after peer review and editorial process. Foreign manuscripts were more difficult to understand in one reading and were best suited for senior tertiary and graduate level students. The local manuscripts were suited for sophomore tertiary students. Originality was significantly correlated with academic readability while plagiarism was significantly correlated with academic readability and originality. The study concludes that technology-based quality assurance of researches is effective in improving readability and originality and in reducing plagiarism in scientific articles.
