Two-Step Cluster Based Feature Discretization of Naive Bayes for Outlier Detection in Intrinsic Plagiarism Detection

Intrinsic plagiarism detection is the task of analyzing a document with respect to undeclared changes in writing style which treated as outliers. Naive Bayes is often used to outlier detection. However, Naive Bayes has assumption that the values of continuous feature are normally distributed where this condition is strongly violated that caused low classification performance. Discretization of continuous feature can improve the performance of Naïve Bayes. In this study, feature discretization based on Two-Step Cluster for Naïve Bayes has been proposed. The proposed method using tf-idf and query language model as feature creator and False Positive/False Negative (FP/FN) threshold which aims to improve the accuracy and evaluated using PAN PC 2009 dataset. The result indicated that the proposed method with discrete feature outperform the result from continuous feature for all evaluation, such as recall, precision, f-measure and accuracy. The using of FP/FN threshold affects the result as well since it can decrease FP and FN; thus, increase all evaluation

Study to determine potential flight applications and human factors design guidelines for voice recognition and synthesis systems

A study was conducted to determine potential commercial aircraft flight deck applications and implementation guidelines for voice recognition and synthesis. At first, a survey of voice recognition and synthesis technology was undertaken to develop a working knowledge base. Then, numerous potential aircraft and simulator flight deck voice applications were identified and each proposed application was rated on a number of criteria in order to achieve an overall payoff rating. The potential voice recognition applications fell into five general categories: programming, interrogation, data entry, switch and mode selection, and continuous/time-critical action control. The ratings of the first three categories showed the most promise of being beneficial to flight deck operations. Possible applications of voice synthesis systems were categorized as automatic or pilot selectable and many were rated as being potentially beneficial. In addition, voice system implementation guidelines and pertinent performance criteria are proposed. Finally, the findings of this study are compared with those made in a recent NASA study of a 1995 transport concept

A scientometric review of management of prefabricated construction from 2011–2021

Prefabricated construction (PC) is an increasingly popular method of construction utilized globally due to its high productivity and efficient performance. PC as an advanced building technique is susceptible to problems such as the immaturity of the PC industry’s development, inability to realize production benefits, and application-related risks and uncertainties. The management of PC (MPC) can be applied to resolve these difficulties and generally enhance performance. Reviews pertinent to the MPC are scarce, making it challenging to concentrate and comprehensively summarize the research situation of the MPC. The MPC review was conducted by Li et al. in 2014. However, there has been a lot of change in the MPC research field. Therefore, this study is an extension of the work of Li et al. (2014). This article aims to analyze and summarize the current research situation and future trends of the MPC, employing a bibliometric search and scientometric analysis from MPC-related publications between 2011 and 2021. This paper outlines current research topics, gaps, and future development from four perspectives based on publications gathered: (1) PC development, (2) PC performance management, (3) PC life cycle management, and (4) technological applications in the MPC. Based on the discussion of these four performance indexes, the following future research directions are proposed: (1) PC industry development considering a combination of Industry–University–Research, (2) the performance impact of management methods and technologies, (3) the rationality of management methods and technologies. This study is vital for scholars to understand MPC research and to conduct further research

Virtual Reality Games for Motor Rehabilitation

This paper presents a fuzzy logic based method to track user satisfaction without the need for devices to monitor users physiological conditions. User satisfaction is the key to any product’s acceptance; computer applications and video games provide a unique opportunity to provide a tailored environment for each user to better suit their needs. We have implemented a non-adaptive fuzzy logic model of emotion, based on the emotional component of the Fuzzy Logic Adaptive Model of Emotion (FLAME) proposed by El-Nasr, to estimate player emotion in UnrealTournament 2004. In this paper we describe the implementation of this system and present the results of one of several play tests. Our research contradicts the current literature that suggests physiological measurements are needed. We show that it is possible to use a software only method to estimate user emotion
