An Ensemble approach for feature selection and classification in intrusion detection using Extra-Tree algorithm

The number of attacks increased with speedy development in web communication in the last couple of years. The Anomaly Detection method for IDS has become substantial in detecting novel attacks in Intrusion Detection System (IDS). Achieving high accuracy are the significant challenges in designing an intrusion detection system. It also emphasizes applying different feature selection techniques to identify the most suitable feature subset. The author uses Extremely randomized trees (Extra-Tree) for feature importance. The author tries multiple thresholds on the feature importance parameters to find the best features. If single classifiers use, then the classifier's output is wrong, so that the final decision may be wrong. So The author uses an Extra-Tree classifier applied to the best-selected features. The proposed method is estimated on standard datasets KDD CUP'99, NSL-KDD, and UNSW-NB15. The experimental results show that the proposed approach performs better than existing methods in detection rate, false alarm rate, and accuracy.

Research on English Online Test Platform Based on Real-Time Web Communication Technology

Due to the multiattribute and multi-related problems of the target English test platform, the efficiency of the platform is low. In order to solve the problem of insufficient control of the difficulty of the test questions in the process of English test paper generation, this paper designs an English test platform based on real-time network communication technology. The English test platform designed in this paper includes three modules: user management module, question bank management module, and test paper management module. Among them, in the test paper management module, we extract English test questions according to the test paper generation strategy, then use real-time web communication technology according to the test paper generation target, and, through effective update of pheromone, solve the problem of high test question repetition rate in automatic test paper generation and design the network. The self-learning platform and English test platform modules have completed the design of the English test platform based on real-time network communication technology. The experimental results show that the designed English test platform has a high success rate, quick test paper generation time, and good application value.

Application of Web Communication Relationship Management in Small and Medium Enterprises

Small and Medium Enterprises (UKM) in Indonesia are still managed traditionally since the touch of information technology is not optimal. On the other hand, the number of customers or transactions made by UKM may no longer be of small value. One modern business approach is to pay attention to customer factors, not only before the transaction but also after the transaction. Applications in the field of information technology in this domain are called Customer Relationship Management (CRM). This research tries to develop a CRM model adapted to the community's culture and the SME business model in Indonesia and considers the penetration of information technology in general. The approach used is to use the Prototype model in which the system creation process is structured and has several stages that must be passed so that the information system becomes better and easier. The results show the small and medium businesses can make CRM simpler and more generic

Edukasi Kesehatan Kulit Perempuan Indonesia melalui Media Sosial pada Akun Instagram @hi.flawless

Content marketing has become an essential part of any social media marketing strategy. However, the effectiveness of a content marketing strategy through social media will be determined by its alignment with the prevailing communication model. This study aims to analyze the communication model that takes place in the marketing of educational content regarding the health of Indonesian women's skin on Instagram @ hi.flawless and determine the effectiveness of the content marketing based on the communication model that occurs. This study uses a qualitative approach with a netnographic method. Data collection methods are through observation and interviews, while data analysis techniques use data reduction, data presentation, and drawing conclusions analysis methods. This research shows that the communication model that occurs is Schramm's interactional communication model which can then be further developed into a multistep non-linear communication model and advanced web communication. The use of Indonesian women's skin health education as content for marketing on Instagram @ hi.flawless is known to be in line with the prevailing and effective communication model to be implemented, seen from the relatively high level of consumer involvement and the increase in sales that have occurred. Keywords: communication model, content marketing, education, social media

Communicating Sustainable Tourism in English and Italian: A Contrastive Analysis

Sustainable tourism has become a popular field of research over the last decades; yet, while acknowledging that sustainable tourism requires communication strategies different from those of mainstream tourism, scholars have paid little attention to this area of language. Based on two parallel corpora, this study explores the discursive representation of sustainable tourism in web communication in English and in Italian. The methodological framework adopted is that of Corpus Assisted Discourse Studies. The analysis suggests that the Italian representation of sustainable tourism is characterized by a distant stance towards readers and relies on a strong polarization between ‘good’ tourism and ‘bad’ tourism. Communication in English instead relies on proximal person deixis and on the creation of value around responsible tourism by means of factual information rather than on mere evaluation.

Web Communication: A Content Analysis of Green Hosting Companies

While many studies in the field of environmental communication have focused on exploring the environmental impact of social media, this research paper takes a different turn. It investigates, through a qualitative content analysis, 391 websites that support and provide green hosting services. This study is considered the first in the field that aims to examine in-depth how these green websites tend to communicate their green services. Therefore, its contribution is to enhance the relevant bibliography and present more insights regarding green websites and sustainability. The results showed that most of the websites were trying to highlight the positive impact their services will have on the environment. In addition, many websites tried to educate their consumers concerning sustainable development and make them part of a broader green cultural tradition. Nevertheless, on many websites, green hosting seemed a supplementary factor for choosing the company’s services.

Sentiment analysis as a tool for assessing the negative impact of tourism on a destination

This article presents the deliverables of the analysis of the experiences of the visitors to the Sochi resort, which is one of the criteria for assessment of the risk of problems caused by excessive tourism pressure. The authors highlight the influence of perception and experiences of the visitors and their informal web communication on the creation of the area’s image. The visitors’ reviews of the resort on TripAdvisor were studied using sentiment analysis. The article outlines the essence of the sentiment analysis method, the reasons for its choice to study the visitors’ attitude towards the Sochi resort, and the relevance of determining the experiences of its visitors. The authors describe the process of studying 33,475 city visitors reviews in 2011-2021 of 58 Sochi tourist attractions and makes conclusions about the visitors’ attitude towards the city, the assessment of its attractions, areas, the level of satisfaction of the tourists from various regions with their vacation. The authors underline predominance of positive reviews and confirms broader possibilities of the sentiment analysis method in comparison with traditional methods of studying public opinion and the possibility of obtaining an objective view of the area image with this method.
