The Web has created new opportunities for interactive problem solving and design by large groups. In the context of robotics, we have shown recently that a crowd of non-experts are capable of designing adaptive machines over the Web. However, determining the degree to which collective contribution plays a part in these tasks requires further investigation. We hypothesize that there exist subtle...

A web-based dispatching system for autonomous mobile service robots is presented. The system is composed of an extensible number of physical and software components. They represent and control objects like robots, doors, cameras and elevators or software components like a job scheduler and a database manager. Components communicate via radio link and Ethernet. Autonomously operating components ...

In this paper we investigate the effectiveness of ensemble-based learners for web robot session identification from web server logs. We also perform multi fold robot session labeling to improve the performance of learner. We conduct a comparative study for various ensemble methods (Bagging, Boosting, and Voting) with simple classifiers in perspective of classification. We also evaluate the effe...

Introduction: In web robot detection it is important is to find features that are common characteristics of diverse robots, in order to differentiate between them and humans. Existing approaches employ fairly simple features (e.g. empty referrer field, interval between successive requests), which often fail to reflect web robots' behaviour accurately. False alarms may therefore occur unacceptab...

Recent industry reports assure the rise of web robots which comprise more than half of the total web trac. Œey not only threaten the security, privacy and eciency of the web but they also distort analytics and metrics, doubting the veracity of the information being promoted. In the academic publishing domain, this can cause articles to be faulty presented as prominent and inƒuential. In this ...

Purpose – This paper investigates the impact and techniques for mitigating the effects of web robots on usage statistics collected by Open Access institutional repositories (IRs). Design/methodology/approach – A review of the literature provides a comprehensive list of web robot detection techniques. Reviews of system documentation and open source code are carried out along with personal interv...

This paper addresses the dynamic path planning for two mobile robots in unknownenvironment with obstacle avoidance and moving target tracking. These robots must form atriangle with moving target. The algorithm is composed of two parts. The first part of thealgorithm used for formation planning of the robots and a moving target. It generates thedesired position for the robots for the next step. ...

Web spam is an escalating problem that wastes valuable resources, misleads people and can manipulate search engines in achieving undeserved search rankings to promote spam content. Spammers have extensively used Web robots to distribute spam content within Web 2.0 platforms. We referred to these web robots as spambots that are capable of performing human tasks such as registering user accounts ...

As the size of the Web continues to grow, searching it for useful information has become increasingly difficult. Researchers have studied different ways to search the Web automatically using programs that have been known as spiders, crawlers, Web robots, Web agents, Webbots, etc. In this chapter, we will review research in this area, present two case studies, and suggest some future research di...
