However, amidst this vast sea of user-generated content, a glaring void persists a definitive rating system capable of distilling the nuanced sentiments embedded within these diverse commentaries. This study thus emerges as a pioneering endeavor, poised to bridge this crucial gap in sentiment analysis. Leveraging the transformative potential of the Word2vec methodology in the preprocessing phase, researchers embark on a comprehensive journey to classify comments on a meticulous 1-5 rating scale, thereby unraveling the multifaceted spectrum of sentiments encapsulated within them. Complementing this groundbreaking approach, the Random Forest classification model is harnessed to bolster the analytical prowess of the study. The resultant accuracy score of 60.4% stands as a testament to the study's significant strides towards achieving a deeper understanding of comment sentiment in the realm of social media. However, this is merely the inception of a promising trajectory; the study's findings hold the promise of not only refining sentiment analysis techniques but also revolutionizing diverse sectors, from market research to product development. With this study, the narrative of sentiment analysis transcends the confines of academia, beckoning forth a new era of nuanced comprehension and meaningful engagement within the sphere of social media commentary. As the study concludes, it leaves behind a compelling call to action, inviting further exploration and innovation in this dynamic field.","PeriodicalId":32370,"journal":{"name":"IJISCS International Journal of Information System and Computer Science","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136058047","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}

The first problem is the absence of Standard Operating Procedures (SOPs) for documenting IT risks. Additionally, there have been instances of system downtime on the local servers, affecting both company and client data. Furthermore, data loss has occurred for employee records, financial data, inventory data, and purchasing data from the on-premises company server. To assess the capability level of the company's IT governance, the COBIT 2019 framework was implemented, focusing on operational and security areas. An approach was undertaken to enhance services and operations within the company. The results of the capability level measurement for process objective APO12 indicated that it has reached level 2, with a target capability level of level 3. On the other hand, process DSS01 successfully achieved level 3, meeting its target capability level, while process DSS02 reached level 2 with a target capability of level 3. This suggests that there is a 1-level gap in the APO12 and DSS02 processes. The recommendation given to the company is to concentrate on risk management, finding a balance between the costs and benefits of managing IT-related risks. Moreover, it is advised to minimize disruptions by resolving user incidents promptly.","PeriodicalId":32370,"journal":{"name":"IJISCS International Journal of Information System and Computer Science","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136036184","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}

Our dataset was taken from Mbujimayi airport in the DRC. So, having the real-world data at our disposal, we used these Machine Learning tools to interpret and understand what happened by training the three models separately, and draw the conclusion as to which was the best model. Then, we used the three models to make some predictions about what our environment will be like tomorrow, and to draw conclusions and make decisions about whether or not our climate is already facing climate change. Three models are used: Decision tree, k-nearest neighbor and neural network, the analysis reveals that of the three models tested, the decision tree scored 81.8% after training with an average prediction of 71.5%, in second place we have the K-nearest neighbor with a score of 70% after training with an average prediction of 70, 8% and the cloture neural network with 64% training and an average prediction of 66.1%.

The Procurement Division of PT XYZ Life Insurance in implementing the e-procurement system will try to be evaluated using the VAL IT 2.0 method. The implementation of VAL IT is one of the frameworks that can be used to conduct an information technology governance management audit or IT Governance. The VAL IT 2.0 Framework analysis used in this study's conclusion to determine the state of the e-procurement system's implementation as part of operational technology management at the company PT XYZ Life Insurance yielded results showing that the highest average GAP Maturity Level is found in the Portfolio Management domain analysis at 1.11, which is different from the level or value 5 of the expected maturity level.
