The Malay language is widely spoken, especially in the Southeast Asian region, but there is a lack of Natural Language Processing (NLP) tools such as Malay corpora and Part-of-Speech (POS) taggers. Existing NLP tools are mainly based on Standard Malay of Malaysia and Indonesian language, but there is none for the Bruneian Malay. We addressed this issue by designing a Standard Brunei Malay corpus consisting of over 114,000 lexical tokens, annotated using 17 Malay POS tagsets. Furthermore, we implemented two commonly used POS tagging techniques, Conditional Random Field (CRF) and Bi-directional Long Short-Term Memory (BLSTM), to develop Bruneian POS taggers and compared their performances. The results showed that both CRF and BLSTM models performed well in predicting POS tags on Bruneian texts. However, CRF models outperform BLSTM, where CRF using all features achieved an F-Measure of 92.06% on news articles and 90.71% of F-Measure on crime articles. Adding a batch normalization layer to the BLSTM model architecture increased the performance by 7.13%. To further improve the BLSTM models, we suggested increasing the training data and experimenting with different hyperparameter settings. The findings also indicated that modelling BLSTM with fastText has improved the POS prediction of Bruneian words.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66333721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We could translate texts from 12 different regional languages into Indonesian using machine translation experiments. We increased the accuracy of machine translation for 12 extremely low-resource languages by using several monolingual corpus sizes on the language model’s target side. Since many Indonesian sources are available, we added this corpus to improve the model’s performance. Our study aims to analyze and evaluate the impact of different language models trained on various monolingual corpus on the accuracy of machine translation. The increase in accuracy when enlarging the monolingual corpus is not observed every time, according to our experiments. Therefore, it is necessary to perform several experiments to determine the monolingual corpus to optimize the quality. Experiments showed that Melayu Pontianak achieved the highest bilingual evaluation understudy improvement point. Specifically, we found that by adding a monolingual corpus of 50–100K, they performed a bilingual evaluation understudy improvement point of 2.15, the highest improvement point they reached for any of the twelve languages tested.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135052618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This type of architecture is used by several firms globally due to its robust security. The Zero Trust security implementation in the Philippines is very low and it shows by looking at the number of cyberattacks that Philippine companies experience. A prominent form of cyberattack is ransomware that endangers that sensitive information that most companies hold. Ransomware attacks are common, and this is where attackers would lock certain files and will only be unlocked when the victim would pay the appropriate ransom for the information. The Philippines has been deemed by international firms as a risky venture since the cybersecurity levels are low. There are also reports that major companies in the Philippines are victims of large-scale ransomware attacks. This study aims to give an in-depth explanation of Zero Trust and see its fundamental aspects that makes it a better option. This exploratory study considers the possible capabilities of the said architecture to combat ransomware in the context of the Philippines.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135649644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Macroscopic and microscopic delay factors are discussed. In this research, we proposed new features that, to the best of our knowledge, were never used in previous studies, namely departure Part and Arrival Part of the day (Mornings, Afternoons, Evenings, Nights) and type of aircraft. U.S. domestic flight data for the year 2018, extracted from the Bureau of Transportation Statistics (BTS), were adopted in order to train the predictive model. We used efficient Machine Learning classifiers such as Decision Trees, K-Nearest Neighbors, Random Forest and Multilayer Perceptron. To overcome the issue of imbalanced data, sampling techniques were performed. We chose Grid Search technique for best parameters selection. The performance of each classifier was compared in terms of evaluation metrics, parameters tuning, data sampling and features selection. The experimental results showed that tuning and sampling techniques have successfully generated the best classifier which is Multilayer Perceptron (MLP) with an accuracy of 98.72% and a higher number of correctly classified flights.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136202086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Still, for some businesses that rely on the on-site presence of employees, this was a lethal blow. As time passed, restrictions got looser and allowed people to strike a balance between on-site and remote work. Thus, tracking people's indoor movements for purposes involving activity inference, security, and contact tracing is more crucial than ever before. This research explores the applicability of (Radio Frequency Identification) RFID contactless smart cards in tracking people's movement within an enclosed establishment by building a proof-of-concept prototype that allows the mentioned purposes. Furthermore, the system underwent multiple test phases to verify that the system meets the functional and non-functional requirements listed to ensure the system's operational success. Consequently, the test results prove that: 1) the system is behaving as intended;2) the system is secure from known high-risk vulnerabilities;and 3) the system satisfies user requirements and standards, thus fulfilling the functional and non-functional requirements for a human-tracking movement system. © 2023 by the authors.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66329993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper focuses on the vulnerabilities around Wi-Fi networks that people are unaware of. Discussing the risks of using free internet is viable as public places in the Philippines have started implementing free Wi-Fi networks. Along with this, the Department of Information and Communication Technology (DICT) of the Philippines is expanding the number of free Wi-Fi to help the Filipinos adjust to the new normal caused by the pandemic. With the increase of internet access, Filipinos should be informed of the risks they may have. In this study, the security of free Wi-Fi has been exploited through various technical methods of Wi-Fi penetration testing. The study simulated penetration testing using the Kali Linux in a virtual environment from consented Wi-Fi owners. The overall result of the study shows that free Wi-Fi networks in public areas may not be safe.
