Applying Web and Information Integration Technologies for Intensified Construction Process Control

Purpose: Nature of being accessible to all categories of users is one of the primary factors for enabling the wider reach of the resources published through World Wide Web. The accessibility of websites has been analyzed through W3C guidelines with the help of various tools. This paper presents a multi-tool accessibility assessment of government department websites belonging to the Indian state of Jammu and Kashmir. A comparative analysis of six accessibility tools is also presented with 14 different parameters.Materials and methods: The accessibility analysis tools used in this study for analysis are aChecker, Cynthia Says, Tenon, wave, Mauve, and Hera. These tools provide us the results of selected websites accessibility status on Web Content Accessibility Guidelines (WCAG) 1.0 and 2.0.Results: It was found that there are variations in accessibility analysis results when using different accessibility metrics to measure the accessibility of websites. In addition to this, we have identified the guidelines which have frequently been violated. It was observed that there is a need for incorporating the accessibility component features among the selected websites. This paper presents a set of suggestions to improve the accessibility status of these sites so that the information and services provided by these sites shall reach a wider spectrum of audience without any barrier.Implications for rehabilitationThe following points indicates that this case study of JKGAD websites comes under Rehabilitation focused on Visually Impaired users.Due to the universal nature of web, it should be accessible to all according to WCAG guidelines framed by World Wide Web Consortium.In this paper we have identified multiple accessibility barriers for persons with visual impairment while browsing the Jammu and Kashmir Government websites.Multi-tool analysis has been done to pin-point the potential barriers for persons with visually Impaired.Usability analysis has been performed to check whether these websites are suitable for persons with visual impairment.We provide some valuable suggestions which can be followed by developers and designers to minimize these potential accessibility barriers.Based on aforementioned key points, this article helps the persons with disability especially Visually Impaired Users to access the web resources better with the implementation of identified suggestions.

Informational web sites on the World Wide Web (WWW) are another means for extension educators to transfer information to a clientele and provide access to new audiences. One of the problems inherent in the utilization of this new technology is the amount of effort required by those involved in order to become proficient enough to accomplish their goal of sharing information through a web site. Through the use of a HTML editor and the assistance from staff knowledgeable about the WWW, a web site on a main campus server was created by untrained off-campus personnel at a remote site to provide information on commercial vegetable production. Planning of the web site included targeting potential audiences, determining what information would be shared from the site, and building a team of extension and research personnel that would provide information and act as reviewers for web publications. Assistance in the form of graphics and general know how were supplied by departmental specialists. After development, the web site was maintained and refined on a regular basis through the utilization of the HTML editor and a web file transfer program.

The task of an information integration system is to combine data residing at different sources, providing the user with a unified view of them, called global schema. Users formulate queries over the global schema, and the system suitably queries the sources, providing an answer to the user, who is not obliged to have any information about the sources. Recent developments in IT such as the expansion of the Internet and the World Wide Web, have made available to users a huge number of information sources, generally autonomous, heterogeneous and widely distributed: as a consequence, information integration has emerged as a crucial issue in many application domains, e.g., distributed databases, cooperative information systems, data warehousing, or on-demand computing. Recent estimates view information integration to be a $10 Billion market by 2006 [14].

Developing secure web applications is a difficult task because the original purpose of the World Wide Web (WWW) was to freely share information. This paper presents a prototype for a platform-independent secure geospatial visualization and collaboration web application. This system is developed using object-oriented system design methodology. It integrates software engineering, web security, visualization and Java technologies with the WWW to enable production, dissemination, and use of imagery and geospatial information on a hierarchical level through the WWW. Several visualization modules on the client side are developed using the Model-View-Controller design pattern technology. These modules are plug-in and reusable components for other similar applications. A Visualization Web Bridge and Data Providers on the server side are designed and implemented to bridge the gap between the Internet users and the remote geospatial databases. Several Internet security mechanisms are implemented to secure system configuration, to authenticate and authorize data access, and to secure information sharing. The system is an open and extensible source. The application results demonstrate that this system provides a certain level of security, and that users have flexibility to query, visualize, manipulate, and analyze real-time remote geospatial data. It exhibits that multiple users in geographically dispersed organizations can conveniently collaborate and share information as well as 3D images through this system. It also demonstrates that using object-oriented system design and design pattern provides a great chance for software reuse and increases the system flexibility.

Rweb is a freely accessible statistical analysis environment that is delivered through the World Wide Web (WWW). It is based on R, a well known statistical analysis package. The only requirement to run the basic Rweb interface is a WWW browser that supports forms. If you want graphical output you must, of course, have a browser that supports graphics. The interface provides access to WWW accessible data sets, so you may run Rweb on your own data. Rweb can provide a four window statistical computing environment (code input, text output, graphical output, and error information) through browsers that support Javascript. There is also a set of point and click modules under development for use in introductory statistics courses.

Recent work on information integration has yielded novel and efficient solutions for gathering data from the World Wide Web. However, there has been little attention given to the problem of providing information management capabilities that closely model how people interact with the web in productive ways - not only collecting information, but monitoring web sites for new or updated data, sending notifications based on the results, building reports, creating local repositories of information, and so on. These needs are unique to the dynamic nature of information in a networked environment. In this paper, we describe Theseus, an efficient plan execution system for information management agents. Through its plan language, Theseus supports a number of capabilities which enable practical information management, including repeated and periodic query execution, conditional plan declarations, query result aggregation, and flexible communication of results. The Theseus executor system focuses on efficiency, with support for data pipelining, and dataflow-based, event driven parallel execution. With Theseus, users can automate the complex but practical ways in which they interact with the web, for both information gathering and management.

The Health Care Network (HCN ) related information of a country is one of the most influential fields of data sharing and integrating with disparate data sources of physical world and compatible health care organizations on the exponentially growing World Wide Web (WWW ) for improving and maintaining health related services of mass people. Although these accessible HCN related unstructured or semi-structured data in multiple heterogeneous repositories on the web originate challenges to develop a smarter method in finding specific information using traditional keyword-based search engines. Moreover, it is also a formidable task to harmonize spatial data with our HCN for exploring implicit knowledge that assist people in making their decisions regarding of health services and it is getting researchers' attention at a rapid pace. In this regard, we applied the Physical-Cyber-Social (PCS) computing approach on HCN that demonstrates the feasibility of semantic web technologies to represent domain information in the machine understandable format and we also integrate data from accessible Cyber Space Data Sources (CSDSs) to address these challenges. We published our HCN related data using Resource Description Framework (RDF ) to build a knowledge-base. We call this repository as HCN - BD, which is HCN related machine understandable data source of Bangladesh. This yields a huge knowledge graph with 0.25 million nodes, i.e. RDF triples to facilitate reasoning important information pattern by a graph based query language, SPARQL. Furthermore, we integrate this semantic repository with our generic spatial knowledge-base, Geo - Bangladesh, a machine understandable geographic data source related to the administrative structure of Bangladesh, to examine health care locations using SPARQL and therefore, we achieved the semantic interoperability in our Linked Open Data (LOD) application. Moreover, our research effectively addresses nearest health care centers using real time spatial data from Global Positioning System (GPS) and maps these locality to increase searching ability by mass people.

The widespread use and expansion of the World Wide Web has revolutionized the discovery, access, and retrieval of information. The Internet has become the doorway to a vast information base and has leveraged the access to information through standard protocols and technologies like HyperText Markup Language (HTML), active server pages (ASP), Java server pages (JSP), Web databases, and Web services. Web services are software applications that are accessible over the World Wide Web through standard communication protocols. A Web service typically has a Webaccessible interface for its clients at the front end, and is connected to a database system and other related application suites at the back end. Thus, Web services can render efficient Web access to an information base in a secured and selective manner. The true success of this technology, however, largely depends on the efficient management of the various components forming the backbone of a Web service system. This chapter presents an overview and the state of the art of various management approaches, models, and architectures for Web services systems toward achieving quality of service (QoS) in Web data access. Finally, it discusses the importance of autonomic or self-managing systems and provides an outline of our current research on autonomic Web services.

Online finding aids, internet search tools, and increased access to the World Wide Web have greatly changed how patrons find archival collections. Through analyzing eighteen months of access data collected via web analytics tools, this article examines how patrons discover archival materials. Contrasts are drawn between access from library catalogs and from online search engines, with the latter outweighing the former by an overwhelming margin, and argues whether archival description practices should change accordingly. The past decade brought a revolution in intellectual access to archival collections through the emergence of the online finding aid. These tools, created in a multiplicity of formats (EAD, HTML, PDF, and others), have made it possible for researchers anywhere to use an Internet connection to find materials in archives. Since archivists first introduced this genre of digital documents to support unmediated discovery, they have been accompanied by questions about their use and usability. Tools exist to measure access counts and the pathways followed to these finding aids, but to date very little has been published to show whether these tools are being used for this purpose, or what the results are if they are being used. This article will examine the experience of one repository, Manuscripts, Archives, and Special Collections (MASC) at the Washington State University Libraries, in collecting and analyzing data about the use of online finding aids. By 2008, MASC had well over eight hundred HTML finding aids online but no real numeric data 1 O'English: Applying Web Analytics to Online Finding Aids Published by DigitalCommons@USU, 2011 either on how often they were being accessed or on how they were found. In an effort to gather this data, MASC staff placed code from Google Analytics, a statisticsgathering Web service, on each finding aid webpage, as well as on other local gateway and digital collections pages. The intent was to explore the paths patrons follow to finding aids with the hope of improving access, as well as gaining patron-derived information that would help establish priorities for processing collections from the repository backlog and to determine which processed collections might benefit from further attention. The results of the statistical analysis provide useful data on where and how MASC users access our finding aids. Prior to the age of digital finding aids, their paper predecessors were found through various methods, which were generally predictable and well-defined, including online and analog library catalogs, published listings, and mediation by archives staff in person or by telephone. As the digital age emerged, many archives channeled substantial resources into major conversion projects, digitizing finding aids and often creating access to them through existing or new MARC records in online library catalogs. Digital search tools have become increasingly powerful and widespread, and social media have emerged as another path to online finding aids. Archivists with quantitative and qualitative data about the use of online finding aids can make better-informed decisions about the most effective ways to support discovery. The findings in this study suggest that it may again be time to change focus, shifting resources away from catalogs and toward the finding aids themselves.

Sensors can sense different phenomena of the real world, such as environmental temperature, humidity and pressure, so they have wide applications in the fields of all kinds of sensing and monitoring. However, heterogeneous sensing devices, networks and data hinder the integration of the applications. Multi-source data fusion technology is used to monitor different environmental parameters by a variety of different types of sensors and then to process the different environmental parameters by the mathematical algorithm to judge the occurrence of some phenomenon. A large number of calculations are needed in the algorithm and different algorithms are used for the particular issues. The technology of Web of Things is used to shield the difference of the underlying sensing devices, networks and data by Web technology in order to provide a good platform for information integration. Based on this, a light-weight rule-based practical method is adopted to integrate the fine-grained multi-source data sensed under WoT platform into the high-level information, which can support multiple application scenarios at the same time and sends the procured information to the decision center by the real-time Web technology.

Easy access to accurate and up to date information plays an important role in optimizing the performance of manufacturing enterprises. Networks play a definite role in the integration of shop-floor information and business system information in the informational age and the related new economy. Integrated automation achieves the transparency and creates a consistent flow of data. Information portals of e-manufacturing era provide an information aggregation, and decision support infrastructure that delivers information to every user. WAP, an underlying protocol, allows access to Internet and World Wide Web from any wireless device. The concept of WAP boils down to the facts that anyone with a digital cellular device should be able to do limited Web surfing from anywhere, at their convenience to perform routine transaction. This paper describes a method to reuse the existing Internet infrastructure and transforming the information to wireless/mobile devices.

As the Internet becomes more accessible to a wider cross-section of the population, libraries, computer scientists, and the publishing industry are becoming more involved with the development of Internet services. The university community is in a unique position to combine professionals from these three departments in a collaborative effort to look at trends in the use of the Internet, and to work together to create resources for those users. In creating a partnership between the areas of Library Affairs, Information Technology and the University Press, Southern Illinois University at Carbondale (SIUC) brought together the varying views and expertise of each constituency to create a model for partnership in the development of scholarly resources using the World Wide Web as an access tool.

During the past two decades, advances in computer technologies combined with telecommunication technologies have lead to the development of the Internet and its most popular application, the World Wide Web. Like many other technologies, the WWW has not been free of problems and challenges. A Delphi technique was utilized to assess a list of issues identified in the existing literature. In addition to this list, the panel of experts who participated in the Delphi study identified other critical issues and eventually ranked them in their order of priority and importance. The critical issue identified in this study provides closer insights into issues affecting the overall utilization and management of Web-enabled technologies and offers many implications and challenges for businesses, governments, and the user community.
