This paper traces the development of World Wide Web Robots and provides an overview of their main functions and workings. The focus is on search robots and illustrations will be drawn from two major search engines: AltaVista and Excite. In the concluding section, prblems associated with the use of Web Robots and their implications for electronic publishing will be examined.

The purpose of this paper is to investigate the impact and techniques for mitigating the effects of web robots on usage statistics collected by Open Access (OA) institutional repositories (IRs).

A close 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 interviews to provide a comparison of the robot detection techniques used in the major IR platforms. An empirical test based on a simple random sample of downloads with 96.20 per cent certainty is undertaken to measure the accuracy of an IR’s web robot detection at a large Irish University.

While web robot detection is not ignored in IRs, there are areas where the two main systems could be improved. The technique tested here is found to have successfully detected 94.18 per cent of web robots visiting the site over a two-year period (recall), with a precision of 98.92 per cent. Due to the high level of robot activity in repositories, correctly labelling more robots has an exponential effect on the accuracy of usage statistics.

This study is performed on one repository using a single system. Future studies across multiple sites and platforms are needed to determine the accuracy of web robot detection in OA repositories generally.

This is the only study to date to have investigated web robot detection in IRs. It puts forward the first empirical benchmarking of accuracy in IR usage statistics.

This paper aims to develop a service‐oriented distributed multi‐robot system based on manufacturing message specification (MMS) and new‐generation distributed object technology – web services for realizing remotely monitoring and controlling multiple heterogeneous robots in the internet environment.

The study presents robot communication model and distributed multi‐robot monitoring and control software structure based on MMS and web services. In particular, monitoring and control software design of MMS concepts in web services environment using Unified Modeling Language model is discussed in detail. In addition, to verify the validity of the proposed design method, a multi‐robot prototype system for robot flexible assemble cell has been achieved. Its Server software is implemented in C++ with Visual Studio.NET being the development environment and Client software is programmed in Java with Borland JBuilder 9 being the development tool.

Finds that the communication structure following MMS can make the multi‐robot monitoring and control system have perfect robustness, interoperability and reconfigurability. Besides, web services technology can conveniently realize MMS services, also can successfully resolve the remote multi‐robot monitoring and control problem among cross‐network, cross‐platform and heterogeneous systems.

Provides an easy and low‐cost method for realizing heterogeneous multi‐robot remote driving. The web‐based distribution of the presented system is critical in enabling capabilities such as e‐manufacturing, e‐diagnostics and e‐maintenance.

The proposed system can be seamlessly integrated into other automated manufacturing systems or management systems in plug‐and‐play fashion. The combination of MMS and web services is in favor of real manufacturing equipments being embedded in the network, so the presented systematic methodology can be a useful reference for constructing web‐based reconfigurable manufacturing systems.

Provides robot communication model based on MMS and web services and presents service‐oriented distributed remote multi‐robot monitoring and control software architecture.

This paper aims to propose a system that generates dialogue scenarios automatically in real time from Web news articles. Then, the authors used the Manzai metaphor, a form of Japanese traditional humorous comedy, in the system. The generated Manzai scenario consists of snappy patter and a humorous misunderstanding of dialogue based on the gap of our structure of funny points. The authors create communication robots to amuse people with the generated humorous robot dialogue scenarios.

The authors propose the following: how to generate funny dialogue-based scenario from Web news and Web intelligence, automatically? How to create direction of robots based on the pre-experiment? The authors conducted experiments from three viewpoints, namely, effectiveness of Manzai scenarios as content, effectiveness of Manzai-Robots as a medium and familiarity of Manzai-Robots.

In this paper, the authors find two points, namely, the new communication style called “human–robots implicit communication-and bridging the knowledge gap using Web intelligence, to communicate smoothly between humans and robots.

Numerous studies have examined communication robots that mutually communicate with people. However, for several reasons, communicating smoothly with people is difficult for robots. One reason is the problem of communication style. Another is knowledge gaps separating humans and robots. The authors propose a new communication style to solve the problems and designate the communication style based on dialogue between robots as “human-robot implicit communication”. The authors then create communication robots to communicate with people naturally, smoothly and with familiarity according to their dialogue.

The Robots.txt and Robots Meta tags constitute a set of instruments that can be used to instruct software robots. However, the current version of Robots.txt and Robots Meta tags are both too simple and ambiguous in an internet world with many potential conflicts, especially in terms of copyright and trespass to chattels. This paper seeks to propose an amendment to the Robots.txt and Robots Meta tags to solve the problems.

Instead of following personal experience, this paper surveys several predominant cases in an attempt to find general principles that can be used as guidelines to amend the Robots.txt and Robots Meta tags.

According to several court cases, the Robots.txt and Robots Meta tags can not only be used to simply allow or refuse the software robots, but also expressing the online copyright authorization policies of webmasters. Any robot following the given policies can prevent possible conflicts, and undoubtedly, any robot ignoring these may be in breach of the law. In terms of adapting to their new roles successfully, the Robots.txt and Robots Meta tags need some supplements and adoption; as a result, the webmasters can express their will more explicitly and avoid unnecessary disputes in relation to copyright authorization scope and trespass to chattels as well.

This paper reveals the new function of the Robots.txt and Robots Meta tags. Based on this new function, this paper points out the disadvantages of the current Robots.txt and Robots Meta tags and proposes new a comprehensive amendment based on this new function.

As the World Wide Web continues its tremendous rate of development, providers of services on the web have difficult decisions to make regarding the deployment of new technologies: should they begin deployment of technologies such as HTML 4.0, CSS 2, Java, Dublin Core metadata, etc., or should they wait until the technologies mature? This paper describes the use of a web auditing/profiling robot utility known as WebWatch which can help service providers by providing information on the uptake of technologies within particular communities. A description of use of the WebWatch software within the UK Higher Education community is given, together with a discussion of the findings.

Today’s Internet technology provides a convenient way for us to develop an integrated network environment for the diversified applications of different robotic systems. To be successful in real‐world applications, Internet‐based robots require a high degree of autonomy and local intelligence to deal with the restricted bandwidth and arbitrary transmission delay of the Internet. This paper describes the first step toward building such an Internet‐based robotic system for teleoperation in the University of Essex. The system has a standard network protocol and an interactive human‐machine interface. Using a Web browser, a remote operator can control the mobile robot to navigate in our laboratory with visual feedback and a simulated environment map via the Internet. The employment of an intuitive user interface enables Internet users to control the mobile robot and implement useful tasks remotely. Although at its first stage, the developed system has the potential to be extended to many real‐world applications such as tele‐manufacturing, tele‐training and tele‐service.

Internet‐based robotic systems have received much attention in recent years. A number of design issues are essential for designing this new type of robotic systems. This paper addresses the Internet time delay, the user interface design and concurrent user access for an Internet‐enabled arm robot. The implementation and application of the Internet‐enabled arm robot in an open control laboratory has been illustrated as a case study.

Describes the use of welding robots for making bridge panels. The system uses a total of 14 sets of High Speed Rotating Arc welding robots and newly‐developed arc sensor techniques are used with both joint end and bead end sensors. A teaching‐less direct CADCAM system was developed to control the robots. The welding robot system is now in commercial operation with welding efficiencies that are twice those possible with conventional processes.

A ‘World Wide Web search engine’ is defined as a retrieval service, consisting of a database (or databases) describing mainly resources available on the World Wide Web (WWW), search software and a user interface also available via WWW. After intro ducing early Internet search engines, which are pertinent as precursors for the current range of WWW search engines, the problems of searching the WWW (link persistence, lack of integrated search software) and the resulting search engine types (keyword or directory) are analysed. Search engines of all types are then compared across their generic features (database content, retrieval software, and search interface), rather than on a search engine by search engine basis. Finally, wider information access issues aris ing from the nature of the Internet and web search engines are considered, and a general strategy for using web search engines is proposed.
