1 Reading Discussions Metcalfe’s Law paper What is metcalfe’s Law? Examples from the Web? How can we utilize it? How semantics contribute to social networks, folksonomy Content creation is not enough, creating links is critical Social context, semantic content Tagging creates folksonomy or social interactions? Link space, content space Metadata, semantic web-represent metadata in a web and machine readable way What is the power of FOAF? And Semantic Web? Using pre-defined ontologies to couple the content space and link space, see RealTravel, vs. Dopplr, persistent URIs Linking the URI space of Web resources – Mashups Web is about creating relationships, semantic web is about representing these relationships to connect link space and content space, this process is a loop process Social tagging success: free typing loose associations

2 Reading Discussions Web Science What is web science, Emerging interdisciplinary field What is Web? Human interaction, Figure 2, micro and macro Web as a graph, scale-free Why Wikipedia is successful, technical model or social model Web is the social machine?, what is social machine? What are research challenges of web science? Coevoluation of technology and social needs Social context Social consequences to enable the greater public exposure and sharing of information that is currently locked in databases Web scientists need to develop new methodologies for gathering evidence and finding ways to anticipate how human behavior will impact on the development of a system which is constantly evolving at such an amazing rate.

3 Reading Discussions Semantic Technology Knowledge management: bring unstructured data into semantic data to enable better searching Information integration: connecting data silos using ontologies, benefits? Semantic wiki Oracle, IBM, Xerox Gartner: metadata… will drive interoperability, automation, cost cutting, better search capabilities, and new business opportunities Semantics for searching?: adding structures to the web The semantic web and information retrieval: bridging the gap, the notion of relevance is changing What are major SW users? Large corporation and government? Semantic for web services: the web of services provenance

4 Reading Discussions Long live the Web Web as electricity Walled social networks Web is yours What is universality What is decentralization? Why important? Your web pages are on the Web, but your data are not -- why and how to understand? Do you have "a single, universal information space"? Do you think Tim's "open standard" is feasible? Why separating the Web from the Internet? What are e Human Rights? Net neutrality Linked data

5 Reading Discussions (optional) Data Preservation Digital data in the cyberworld is analogous to infrastructure in the physical world. Cyberinfrastructure for knowledge economy Figure 1, data cyberinfrastructure Data deluge and data preservation, challenges Adding metadata when preserving your data
