Word clustering based on POS feature for efficient twitter sentiment analysis
Human-centric Computing and Information Sciences - Tập 8 - Trang 1-25 - 2018
With rapid growth of social networking service on Internet, huge amount of information are continuously generated in real time. As a result, sentiment analysis of online reviews and messages has become a popular research issue [1]. In this paper a novel modified Chi Square-based feature clustering and weighting scheme is proposed for the sentiment analysis of twitter message. Along with the part o...... hiện toàn bộ
Indoor positioning and wayfinding systems: a survey
Human-centric Computing and Information Sciences - Tập 10 - Trang 1-41 - 2020
Navigation systems help users access unfamiliar environments. Current technological advancements enable users to encapsulate these systems in handheld devices, which effectively increases the popularity of navigation systems and the number of users. In indoor environments, lack of Global Positioning System (GPS) signals and line of sight with orbiting satellites makes navigation more challenging c...... hiện toàn bộ
PLC-based design of monitoring system for ICT-integrated vertical fish farm
Human-centric Computing and Information Sciences - Tập 7 - Trang 1-19 - 2017
The common cause of the mass mortality of fishes in a fish farm is a power failure. There can be many reasons for the power failures but most of them are the result of natural disasters, systematic faults, ill-willed sabotages, or mistakes of employees. Such incidents usually have a bad influence upon small or medium-scale farmers. To deal with unexpected power failures, this research proposes a s...... hiện toàn bộ
A dynamic attention assessment and enhancement tool using computer graphicsAbstract Training Programs to enhance Math Solving Skills, Memory, Visualization, etc in children are gaining popularity worldwide. Any skill is better acquired, when attention, the basic cognitive ability of the trainee is improved. This study makes an attempt to devise a technique in the form of a Brain Computer Interface (BCI) Game, to assist the trainers in moni... ... hiện toàn bộ

Exploring the affective, motivational and cognitive effects of pedagogical agent enthusiasm in a multimedia learning environment
Human-centric Computing and Information Sciences - Tập 7 - Trang 1-21 - 2017
In a traditional classroom environment, instructor enthusiasm has been shown to enhance student’s emotion, affective perceptions, intrinsic motivation, and cognitive outcome. Additionally, emotional response theory argues that enthusiastic verbal and nonverbal cues of an instructor will induce positive emotional states in learners, which in turn, enact learners’ approach behaviours in the learning...... hiện toàn bộ
SensDeploy: efficient sensor deployment strategy for real-time localization
Human-centric Computing and Information Sciences - - 2017
In order to estimate the location of the user, the previous studies introduced many sensor deployment methods applying the sensor network. The important issues to consider when placing the sensors are a configuration cost and detection area of a sensor network. In other words, the sensors consisting the network should be optimally deployed by taking into account the coverage and connectivity of th...... hiện toàn bộ
MR-Radix: a multi-relational data mining algorithm
Human-centric Computing and Information Sciences - Tập 2 - Trang 1-17 - 2012
Once multi-relational approach has emerged as an alternative for analyzing structured data such as relational databases, since they allow applying data mining in multiple tables directly, thus avoiding expensive joining operations and semantic losses, this work proposes an algorithm with multi-relational approach. Aiming to compare traditional approach performance and multi-relational for mining a...... hiện toàn bộ
SD2PA: a fully safe driving and privacy-preserving authentication scheme for VANETs
Human-centric Computing and Information Sciences - Tập 10 - Trang 1-25 - 2020
The basic idea behind the vehicular ad-hoc network (VANET) is the exchange of traffic information between vehicles and the surrounding environment to offer a better driving experience. Privacy and security are the main concerns for meeting the safety aims of the VANET system. In this paper, we analyse recent VANET schemes that utilise a group authentication technique and found important vulnerabil...... hiện toàn bộ
The shift to 6G communications: vision and requirements
Human-centric Computing and Information Sciences - - 2020
The sixth-generation (6G) wireless communication network is expected to integrate the terrestrial, aerial, and maritime communications into a robust network which would be more reliable, fast, and can support a massive number of devices with ultra-low latency requirements. The researchers around the globe are proposing cutting edge technologies such as artificial intelligence (AI)/machine learning...... hiện toàn bộ
Feature extraction for robust physical activity recognition
Human-centric Computing and Information Sciences - Tập 7 - Trang 1-16 - 2017
This paper presents the development of a Human Activity Recognition (HAR) system that uses a network of nine inertial measurement units situated in different body parts. Every unit provides 3D (3-dimension) acceleration, 3D angular velocity, 3D magnetic field orientation, and 4D quaternions. This system identifies 33 different physical activities (walking, running, cycling, lateral elevation of ar...... hiện toàn bộ
