business registries that are driven by the needs of business users using UDDI and
Semantic MediaWiki.
Paoli et al. [ 26 ] believe that service registries should address all stakeholders.
Current service descriptions only concentrate on the service developers. Service
discovery has technical and business (“semantic”) facets. The technical part of a
service description deals with the syntax of the service interface and is affected by
the underlying SOA infrastructure. The semantic part should reflect the business
objectives of the service. They conclude that traditional information retrieval
techniques based on descriptive terms are clearly insufficient and must be aug-
mented by consideration of each term together with its network of somehow-related
terms. These authors argue that for technical and application reasons the technical
and business aspects of the service description should be kept separate. They also
suggested that UDDI is practically the only standard for advertising services
through service registries. The use of UDDI serves to establish a worldwide service
registry to create a worldwide market of services and enable small and unknown
companies anywhere in the world to offer their innovative services to customers on
the other side of the globe.
The rapid growth of personal and community data on the Web demands effective
Social Webtops , i.e. Web-based infrastructure for users to organise and share online
data [ 27 ]. A social Webtop uses the Web for data storage and provides special
applications for seamlessly moving our daily data process applications onto the
Web. For example, Wikipedia reduces the need for encyclopaedia software on PCs,
and Google Document, an open Web-based alternative, does the same for conven-
tional word processing software. According to these authors, a successful social
Webtop requires many critical capabilities, such as structured data representation,
smart data integration and propagation, provenance-aware social data access con-
trol, Web data persistency and preservation and friendly data access UI.
Bao et al. [ 27 ] argue that a social Webtop should provide versatile concept
modelling supports to facilitate Web users creating, propagating, accessing and
consuming. It should also be aware of social provenance and support both socialisa-
tion that promotes collaborative data generation and consumption, and personalisa-
tion that ensures necessary data privacy protection and customisation. According to
these authors, the Semantic Wiki is not only a general purpose tool for content
management, but also a powerful workbench for building lightweight social Webtop
applications. Social Webtop applications can be developed on internal and external
online data using wiki-based concept modelling and programming power. Each
layer gives a higher level of abstraction of the information than the layer below.

10.5.3 Personal Knowledge Management

A key to success in the modern economy is the management of knowledge.
Knowledge is fundamentally created by individuals [ 28 ]. It is important to support
individuals in their personal knowledge management. According to V
