Credibility Analysis of User-Designed Content Using Machine Learning Techniques

Abstract

Content is a user-designed form of information, for example, observation, perception, or review. This type of information is more relevant to users, as they can relate it to their experience. The research problem is to identify the credibility and the percentage of credibility as well. Assessment of such content is important to convey the right understanding of the information. Different techniques are used for content analysis, such as voting the content, Machine Learning Techniques, and manual assessment to evaluate the content and the quality of information. In this research article, content analysis is performed by collecting the Movie Review dataset from Kaggle. Features are extracted and the most relevant features are shortlisted for experimentation. The effect of these features is analyzed by using base regression algorithms, such as Linear Regression, Lasso Regression, Ridge Regression, and Decision Tree. The contribution of the research is designing a heterogeneous ensemble regression algorithm for content credibility score assessment, which combines the above baseline methods. Moreover, these factors are also toned down to obtain the values closer to Gradient Descent minimum. Different forms of Error Loss, such as Mean Absolute Error, Mean Squared Error, LogCosh, Huber, and Jacobian, and the performance is optimized by introducing the balancing bias. The accuracy of the algorithm is compared with induvial regression algorithms and ensemble regression separately; this accuracy is 96.29%.

Information Environment Quantifiers as Investment Analysis Basis

“…After the above steps, the text will be suitable for conversion into a numeric format to continue the extraction of features (quantification of the resulting list of words). Further, it is possible to compile different indices, calculate the frequency of the presence of particular words, and their correlation with the movement of stock prices (Gayakwad et al 2022).…”

Web Service Implementation “AI Yoga Trainer Using Human Pose Estimation” for Web Discovery

“…The importance of maintaining proper posture for general health and well-being has increased with the prevalence of sedentary lifestyles [3] [4]. Poor posture can cause several muscular-skeletal issues and have a detrimental influence on physical performance numerous muscular-skeletal problems [5] [6], such as back discomfort, restricted mobility, and poor physical performance, can be brought on by poor posture [7] [8]. Keeping appropriate posture in yoga as well as in daily life has become increasingly important to fight these difficulties [2].…”

Performance analysis of Machine Learning Algorithms to classify Software Requirements

“…We present an effective methodology for pre-processing the text data and applying machine learning algorithms to classify the requirements [12] [13]. We compare the performance of the algorithms and provide insights into the accuracy and limitations of each algorithm [14] [15]. Our research contributes to the development of automated approaches for software requirements classification, which can lead to more efficient and reliable software engineering practices [16] [17].…”
