Sentiment analysis and opinion mining on E-commerce site

Sentiment analysis or opinion mining help to illustrate the phrase NLP (Natural Language Processing). Sentiment analysis has been the most significant topic in recent years. The goal of this study is to solve the sentiment polarity classification challenges in sentiment analysis. A broad technique for categorizing sentiment opposition is presented, along with comprehensive process explanations. With the results of the analysis, both sentence-level classification and review-level categorization are conducted. Finally, we discuss our plans for future sentiment analysis research.

IoT application using a unique rectangular 2.4GHz microstrip patch antenna

Internet of Things (IoT)-based applications must be integrated with wireless communication technologies for this make application data easily accessible. The wireless communication system is a crucial component of IoT infrastructure, serving as a bridge for bidirectional connection for data gathering and control message delivery. In this article, a modified meander form microstrip patch antenna for IoT applications in 2.4 GHz ISM (Industrial, Scientific, and Medical) band is suggested.The suggested antenna has a gain of up to 4.01 dBi and an efficiency of up to 90% directivity up to 7.14. Theperformance after simulation of this antenna that is combined with a 2.4GHz radio frequency module and IoT sensors. Having small size and high fractional bandwidth which gives a good performance in IoT application. The patch's length width is 30.2 mm, and its length 47mm at a resonance frequency of 2.4 GHz is 38 mm, with a feeding offset position of 6 mm. The substrate has a height of 1.5 mm that appropriate for short-range IoT applications.
