Texts are now being devoted to explaining how e-business can be practically undertaken, for example see Lawrence et al. (2003). There is a rapidly emerging trend of organisations using Intranet portals for internal business processes and communication between employees and their organisation. This is well documented in this and other books, for example see Tatnall (2004). Systems that deploy Intranet portals with intelligent agents and e-processes have replaced routine procedural knowledge used by clerical and lower level management levels. These portals facilitate self-service as a first step toward developing more knowledge-intensive knowledge management (KM) portal applications. However, the greatest value to be derived from well-designed intranet portals is probably their potential as a KM tool (Lloyd-Walker & Soutar, 2005). Portals must be convenient to use and represent an advantage to users over more traditional means (Peansupap & Walker, 2005a). Also, appropriate change management practices should be adopted when planning, deploying, and applying portals as a tool for KM in an organisation to ensure that an appropriate knowledge sharing culture exists where both the organisation and its staff values and rewards knowledge-sharing (Fernie, Green, Weller, & Newcombe, 2003; Gupta & Govindarajan, 2000; Lloyd-Walker et al., 2005). We will now focus on our main theme of describing a prototype KM portal developed for a major Australian construction contractor. We set aside further detailed discussion of the important diffusion and adoption issues. These are addressed in depth elsewhere (Attewell, 1992; Peansupap & Walker, 2005b; Rogers, 1995). This article is structured as follows. We have provided a brief introduction to knowledge portals in this section and highlighted further references for ICT diffusion. In the next section, we provide background to the prototype KM portal tool to enable readers to understand its scope and limitations. In that section we also briefly explain how a soft systems methodology (SSM) approach facilitated the development of our ideas. We then focus our next section on describing the prototype. This is followed by a brief discussion of future trends and concluding comments. The value of this work lies in its novel approach to designing a knowledge portal and the conceptual work that supports this prototype KM system.","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123822526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also deals with methods for acquiring, storing, retrieving and analysing biological data obtained by querying biological databases or provided by experiments. Bioinformatics applications involve different datasets as well as different software tools and algorithms. Such applications need semantic models for basic software components and need advanced scientific portal services able to aggregate such different components and to hide their details and complexity from the final user. For instance, proteomics applications involve datasets, either produced by experiments or available as public databases, as well as a huge number of different software tools and algorithms. To use such applications it is required to know both biological issues related to data generation and results interpretation and informatics requirements related to data analysis. Bioinformatics applications require platforms that are computationally out of standard. Applications are indeed (1) naturally distributed, due to the high number of involved datasets; (2) require high computing power, due to the large size of datasets and the complexity of basic computations; (3) access heterogeneous data both in format and structure; and finally (5) require reliability and security. For instance, applications such as identification of proteins from spectra data (de Hoffmann & Stroobant, 2002), querying of protein databases (Swiss-Prot), predictions of proteins structures (Guerra & Istrail, 2003), and string-based pattern extraction from large biological sequences, are some examples of computationally expensive applications. Moreover, expertise is required in choosing the most appropriate tools. For instance, protein structure prediction depends on proteins family, so choosing the right tool may strongly influence the experimental results. Recently, there has been much interest from database community and computer science community for bioinformatics. Nevertheless, what is still missing is a high-level environment able to classify tools and provide Web-based easy to use application programming interfaces. In such a way, users can concentrate on the logic of application (i.e., biological aspects) leaving to such platform the work to compose applications, format input data, provide options and parameters, and collect results. Another important requirement is the accessibility of such platform through a Web portal, that is, by using the user interfaces and protocols of the World Wide Web. A bioinformatics Web portal is thus a Web portal that allows access to bioinformatics tools and databases through a Web browser. Moreover, due to the complexity, diversity and a huge number of bioinformatics tools and databases, a bioinformatics Web portal should also support problem formulation, application composition and execution, results visual","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127187297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In their brief lifetime, Web portals have benefited various sectors of the society and found widespread use (Jafari & Sheehan, 2003; Tatnall, 2005). By careful aggregation of information, Web portals simplify access, as well as decrease the time and effort of locating resources on topical themes. In doing so, they have created a sense of community with common interests. It is crucial that a Web portal be able to capture, represent, and syndicate information adequately. To that regard, the Web portals today face the challenges of increasing amounts of information, diversity of users and user contexts, and everincreasing variations in proliferating computing platforms. They need to continue being a successful business model for providers and continue to be useful to their user community in the light of these challenges. This article discusses the potential of Semantic Web technologies in tackling the issues of agility, sustainability, and maintainability of the information architecture of domain-specific Web portals. The organization of the article is as follows. We first outline the background necessary for the discussion that follows and state our position. This is followed by a detailed treatment of social prospects and technical concerns pertaining to knowledge representation of integrating Semantic Web technologies in Web portals. Next, challenges and directions for future research are outlined and, finally, concluding remarks are given.","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127468064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An important aspect of Web portals is the organisation, navigation, labelling, and indexing of their content in order to facilitate searching of information and services (that is, the resources stored as Web portal content). One of the aims of Web portals is to collect and categorize resources (otherwise called content objects), so that users can search, identify, and access the most appropriate resources for their needs. Metadata plays a critical role in such systems. Metadata is defined as structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage a resource. It is often called “data about data” or “information about information” (NISO, 2004; Steinacker, Ghavam, & Steinmetz, 2001). Metadata is used to provide information about resources that do not necessarily need to be displayed on the screen. It can then be used by software such as search engines or content management systems. Examples of information commonly stored as metadata include authorship, publication date, modification date, copyright information, and subject keywords. Metadata can be therefore used in the context of Web portals to describe resources, and thus to facilitate their categorization, storage, search, and retrieval procedures (Duval, Hodgins, Sutton, & Weibel, 2002; Miller, 1996). In this article, we provide an overview of what metadata is, and how it can be used for the description, categorization, and classification of Web portal content. Using the case study of an organic agriculture (OA) Web portal, appropriate metadata for describing OA electronic markets (e-markets) and developing an e-market directory service is presented.","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115530772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
