How SW can benefit from incorporation with existing 'Social Web'.
\r\n"...collaborative generation of metadata... using social networks as a user\r\nbase..."
\r\nUses fb groups created for sharing and organisation of research. Suggests\r\nposting links to useful resources is comparable to annotating the resource.\r\nComments are more metadata.
\r\nPoints out usual stuff of actually generating semantic data being a problem\r\nfor SW.
\r\nSystem requirements:
\r\nReview of existing systems:
\r\n[1] Using existing information to derive semantics from folksonomies\r\n(delicious):
\r\n_X Wu, L Zhang, Y Yu. Exploring social annotations for the Semantic Web.\r\n_Proceedings of the 15th international conference on the World Wide Web,\r\n2006.
[15] Social bookmarking tools and how semantic info aids resource discovery.\r\nProbabalistic model of how resources are annotated:
\r\n_A Plangprasopchok, K Lerman. Exploiting Social Annotation for Automatic\r\n_Resource Discovery. Eprint arXiv, 2007.
\r\n[16] Distributed nature of folksonomies. Improve search mechanisms. Tags not\r\ngreat:
\r\nS Choy, A. Lui. Web Information Retrieval in Collaborative Tagging Systems.\r\nProceedings of International Conference on Web Intelligence, 2006.
\r\n (vs.)
\r\n[17] Rigid taxonomies not great:
\r\n_C Shirky. Ontology is Overrated: Categories, Links, and Tags. Clay Shirky’s\r\n_Writings About the Internet, 2005.
\r\n[18] Methodology for easier browsing of large scale social annotations:
\r\nZ Xu, Y Fu, J Mao, D Su. Towards the semantic web: Collaborative tag\r\nsuggestions. Collaborative Web Tagging Workshop at WWW2006, 2006.
\r\nAll use one annotation per resource, not annotation of content within, so only\r\none lot of metadata about a page.
\r\nMeervisage
\r\n
\r\n
"To aid the process of collaborative annotation of web documents"
\r\nAllows sharing of annotations between subset of SNS users (eg. fb group).
\r\nManagement of users and groups offloaded to third party.
\r\nStored in central annotation store.
\r\nAnnotations contain author, SNS, folksonomies and date. Made from content\r\nwithin.
\r\nMeerkat is "responsible for generating semantic metadata by annotating\r\nexternal web resources." Meervisage for management via social network.
\r\nMeerkat allows a user to edit another user's annotations if they are members\r\nof the same group on facebook.
\r\nPopularity rating of resources rises with fb discussion.
\r\nMeerkat informs browser users if they come across a resource that has been\r\nheavily discussed on fb, and by which group etc.
\r\nMeervisage also provides RSS feed.
\r\nEvaluate by comparing precision and recall metrics of annotations by one user\r\nin an allotted time, and those by a group.
\r\n-> Don't know how this helps to assess quality of annotations; maybe I'm dumb? Find out.
\r\nLimited to private, says it's like that's a good think :s
\r\nOh, because public access would be "laborious and resource intensive".
\r\nAnnotations rated on usefulness and weighted.
\r\n[20] Attempt to describe folksonomies as part of formal ontology. Meervisage\r\ndoesn't; limited to users' viewpoint:
\r\n_S Angeletou, M Sabou, L Specia, E Motta. Bridging the Gap Between\r\nFolksonomies and the Semantic Web: An Experience Report. Workshop: Bridging\r\nthe Gap between Semantic Web and Web 2.0, European Semantic Web Conference,\r\n_2007.
\r\n[9] + [13] are most similar. Have groups, but groups aren't already\r\nestablished networks.
\r\nFuture work
\r\nAnnotating multimedia.
\r\nMatching assigned tags with ontology terms mined from Web.
\r\n[19] Desktop app for annotating text with ontology:
