Human-Centric Cyber Social Computing Model for Hot-Event Detection and Propagation
(Article)Microblogging networks have gained popularity in recent years as a platform enabling expressions of human emotions, through which users can conveniently produce contents on public events, breaking news, and/or products. ... -
A Hybrid Approach for Supporting Adaptivity in E-learning Environments
(Article)Purpose: The purpose of this paper is to identify a framework to support adaptivity in e-learning environments. The framework reflects a novel hybrid approach incorporating the concept of the ECA model and intelligent ... -
A hybrid approach to piecewise modelling of biochemical systems.
(Article)Modelling biochemical systems has received considerable attention over the last decade from scientists and engineers across a number of fields, including biochemistry, computer science, and mathematics. Due to the complexity ... -
A Hybrid Approach to Sentiment Analysis
(Conference)This contribution presents a hybrid approach to Sentiment Analysis (SA) encompassing the use of semantic rules, fuzzy sets, unsupervised machine learning techniques and a sentiment lexicon improved with the support of ... -
A Hybrid Approach to Sentiment Analysis with Benchmarking Results
(Conference)The objective of this article is two-fold. Firstly, a hybrid approach to Sentiment Analysis encompassing the use of Semantic Rules, Fuzzy Sets and an enriched Sentiment Lexicon, improved with the support of SentiWordNet ... -
A Hybrid Approach to the Sentiment Analysis Problem at the Sentence Level
(Article)The objective of this article is to present a hybrid approach to the Sentiment Analysis problem at the sentence level. This new method uses natural language processing (NLP) essential techniques, a sentiment lexicon enhanced ... -
A Hybrid Evaluation Methodology for Human Activity Recognition Systems
(Book chapter)Evaluating human activity recognition systems usually implies following expensive and time consuming methodologies, where experiments with humans are run with the consequent ethical and legal issues. We propose a hybrid ... -
A hybrid evolutionary multiobjective approach for the dynamic component selection problem.
(Article)Component selection is a crucial problem in Component Based Software Engineering (CBSE). CBSE is concerned with the assembly of pre-existing software components that leads to a software system that responds to client-specific ... -
A hybrid genetic algorithm and inver over approach for the travelling salesman problem.
(Article)This paper proposes a two-phase hybrid approach for the travelling salesman problem (TSP). The first phase is based on a sequence based genetic algorithm (SBGA) with an embedded local search scheme. Within the SBGA, a ... -
A hybrid genetic algorithm and tabu search approach for post enrolment course timetabling.
(Article)The post enrolment course timetabling problem (PECTP) is one type of university course timetabling problems, in which a set of events has to be scheduled in time slots and located in suitable rooms according to the student ... -
Hybrid genetic algorithm based on bin packing strategy for the unrelated parallel workgroup scheduling problem
(Article)In this paper we focus on an unrelated parallel workgroup scheduling problem where each workgroup is composed of a number of personnel with similar work skills which has eligibility and human resource constraints. The ... -

A hybrid immigrants scheme for genetic algorithms in dynamic environments
(Article)Dynamic optimization problems are a kind of optimization problems that involve changes over time. They pose a serious challenge to traditional optimization methods as well as conventional genetic algorithms since the goal ... -
A Hybrid Intrusion Detection System for Virtual Jamming Attacks on Wireless Networks
(Article)Wireless communications are vulnerable to certain number of cyber-attacks and intrusion attempts due to the intrinsic openness of the communication channel. Virtual jamming attack stands out among other attacks. This type ... -
Hybrid meta-heuristic algorithms for independent job scheduling in grid computing
(Article)The term ’grid computing’ is used to describe an infrastructure that connects geographically distributed computers and heterogeneous platforms owned by multiple organizations allowing their computational power, storage ... -
Hybrid Multi-agent Architecture (HMAA) for Meeting Scheduling
