Website Evaluation Using Opinion Mining

With the advancement in technology, online shopping has taken a new toll. Customers can access the shopping websites from anywhere with the help of the internet. The websites display all the products for the customer to choose from and the customer can post any review or their opinion on the service of the website. The main aim of this project is to provide users with a rating generated according to the shopping website’s performance and standards. There are numerous shopping websites to visit but the legitimacy of all the websites is questionable. Fraud can occur on a regular basis from illegitimate websites. The users may not get the service as per their expectations. There are many renowned shopping websites which do not match their credibility and in turn disappoints the customers or users. The proposed system evaluates the shopping websites based on the reviews or opinions of the experienced customers. The performance of the website is processed down to certain parameters. According to these parameters a certain rating of that particular website is generated, which helps the customer to decide which website to opt for

284-287Nyctanthes arbor-tristis L., popularly known as Parijataka or Night jasmine, belongs to family Oleaceae. Nyctanthes is commonly grown as a sacred tree in Maharashtra. It is also known for its medicinal cure by the aboriginals residing in this region. Leaves and bark are said to be antibilious and expectorant. Bark in combination with arjuna sadada is considered to be useful in internal injuries and healing of wounds including fractured bones. The decoction of bark is recommended for periodic fever. In spite of these therapeutic uses and easy availability, no detailed pharmacognostic study has been done. The present investigation deals with macroscopic and microscopic evaluation of the stem bark. Various physicochemical parameters were also established. Preliminary Phytochemical screening revealed the presence of phytoconstituents such as alkaloids, tannins, cardiac glycosides, etc. Such a study would serve as a useful tool in standardization of the stem bark

Hardware Implementation of Sobel Edge Detection Algorithm

In the fields of image processing, feature detection, the edge detection is an important aspect. For detection of sharp changes in the properties of an image, edges are recognized as important factors which provides more information or data regarding the analysis of an image. In this work coding of various edge detection algorithms such as Sobel, Canny, etc. have been done on the MATLAB software, also this work is implemented on the FPGA Nexys 4 DDR board. The results are then displayed on a VGA screen. The implementation of this work using Verilog language of FPGA has been executed on Vivado 18.2 software tool
