The Semantic Web Revisited

The original Scientific American article on the Semantic Web appeared in 2001. It described the evolution of a Web that consisted largely of documents for humans to read to one that included data and information for computers to manipulate. The Semantic Web is a Web of actionable information--information derived from data through a semantic theory for interpreting the symbols.This simple idea, however, remains largely unrealized. Shopbots and auction bots abound on the Web, but these are essentially handcrafted for particular tasks; they have little ability to interact with heterogeneous data and information types. Because we haven't yet delivered large-scale, agent-based mediation, some commentators argue that the Semantic Web has failed to deliver. We argue that agents can only flourish when standards are well established and that the Web standards for expressing shared meaning have progressed steadily over the past five years. Furthermore, we see the use of ontologies in the e-science community presaging ultimate success for the Semantic Web--just as the use of HTTP within the CERN particle physics community led to the revolutionary success of the original Web.

How career variety promotes the adaptability of managers: a theoretical model

This paper presents a theoretical model showing how managerial adaptability develops from career variety over the span of the person’s career. By building on the literature of career theory, adult learning and development, and career adjustment, we oVer a new conceptualization of managerial adaptability by identifying its behavioral, cognitive, and socio-emotional dimensions, discuss how these competencies can develop from the variety of managers’ cumulative career experiences, and propose several individual and career-related factors that moderates the relationship between managerial career variety and adaptability

Linking with Meaning: Ontological Hypertext for Scholars

The links in ontological hypermedia are defined according to the relationships between real-world objects. An ontology that models the significant objects in a scholar’s world can be used toward producing a consistently interlinked research literature. Currently the papers that are available online are mainly divided between subject- and publisher-specific archives, with little or no interoperability. This paper addresses the issue of ontological interlinking, presenting two experimental systems whose hypertext links embody ontologies based on the activities of researchers and scholars

Biblical Principles of Music and Worship

Since creation, God\u27s plan for humanity was for the purpose of worship. How we worship matters, and there are stringent guidelines in the Old Testament and the New Testament on how it should be conducted. As society has changed across ages, modes of worship have changed both negatively and positively. This research paper aims to discuss the Biblical principles of music and worship directed toward the worship leader by exploring the principles of worship taken from the Old and New Testaments in the Bible. The review will employ a qualitative explanatory study design to answer the question, what, in addition to gifts and talents, make for a qualified worship leader? Additionally, the sub-questions framed for this study are as follows: What are the correct intentions for the music ministry? Have the changes in musical styles and other significant church worship changes over the years altered the way we worship? Answering these questions will require exploring the Biblical purpose of music, knowing the importance of planning, and developing effective relationships. It will also involve examining the issue of attire and knowing when to stop the music. This study is significant as it will highlight how worship should be conducted to align with God\u27s Word, including the integrity of the heart of the worship leader at a time when the church is witnessing dramatic changes due to technology and globalization. Besides, this review can be used as a reference point for Bible colleges and churches as there is an urgent need to equip worship leaders with the necessary Biblical principles that will help them effectively lead their congregants into God\u27s presence
