PARC's Augmented Social Cognition researchers -- who come from cognitive psychology, computer science, HCI, CSCW, and other disciplines -- focus on understanding how to "enhance a group of people's ability to remember, think, and reason". Through Social Web systems like social bookmarking sites, blogs, Wikis, and more, we can finally study, in detail, these types of enhancements on a very large scale.
Here we summarize recent work and early findings such as: (1) how conflict and coordination have played out in Wikipedia, and how social transparency might affect reader trust; (2) how decreasing interaction costs might change participation in social tagging systems; and (3) how computation can help organize user-generated content and metadata.}, acmid = {1559959}, address = {New York, NY, USA}, author = {Chi, Ed H.}, booktitle = {Proceedings of the 2009 ACM SIGMOD International Conference on Management of data}, doi = {10.1145/1559845.1559959}, interhash = {d24a64ce5e95bae4de9329a467342dee}, intrahash = {d09b484b1036ca8273743cac1992dd7f}, isbn = {978-1-60558-551-2}, location = {Providence, Rhode Island, USA}, numpages = {12}, pages = {973--984}, publisher = {ACM}, title = {Augmented social cognition: using social web technology to enhance the ability of groups to remember, think, and reason}, url = {http://doi.acm.org/10.1145/1559845.1559959}, year = 2009 } @inproceedings{happel2010considering, abstract = {The notions of collaborative information seeking (CIS) and social search have extended the classical model of information seeking and retrieval.

The Wikipedia project, for example, succeeded in creating the by far largest encyclopedia just on the basis of a wiki. Recently, several approaches have been proposed on how to extend wikis to allow the creation of structured and semantically enriched content. However, the means for creating semantically enriched structured content are already available and are, although unconsciously, even used by Wikipedia authors. In this article, we present a method for revealing this structured content by extracting information from template instances. We suggest ways to efficiently query the vast amount of extracted information (e.g. more than 8 million RDF statements for the English Wikipedia version alone), leading to astonishing query answering possibilities (such as for the title question). We analyze the quality of the extracted content, and propose strategies for quality improvements with just minor modifications of the wiki systems being currently used.}, author = {Auer, S{\"o}ren and Lehmann, Jens}, bibsource = {DBLP, http://dblp.uni-trier.de}, booktitle = {ESWC}, crossref = {DBLP:conf/esws/2007}, ee = {http://dx.doi.org/10.1007/978-3-540-72667-8_36}, file = {auer2007what.pdf:auer2007what.pdf:PDF}, groups = {public}, interhash = {2b70ab546da1b45f5350d3ff742c4288}, intrahash = {b8e464b4a672530bf91c9189f17cca73}, pages = {503-517}, timestamp = {2010-02-23 14:49:49}, title = {What Have Innsbruck and Leipzig in Common?

Social aspects can be categorized into social interaction, social communities, social groups or any kind of behavior that emerges from interlinking, overlapping or similarities between interests of a society. These social aspects are dynamic and emergent. Therefore, interlinking them in a social structure, based on bipartite affiliation network, may result in isolated graphs. The major reason is that as these correspondences are dynamic and emergent, they should be coupled with more than a single affiliation in order to sustain the interconnections during interest evolutions. In this paper we propose to interlink actors using multiple tripartite graphs rather than a bipartite graph which was the focus of most of the previous social network building techniques. The utmost benefit of using tripartite graphs is that we can have multiple and hierarchical links between social actors. Therefore in this paper we discuss the extraction, plotting and analysis methods of tripartite relations between authors, articles and categories from Wikipedia. Furthermore, we also discuss the advantages of tripartite relationships over bipartite relationships. As a conclusion of this study we argue based on our results that to build useful, robust and dynamic social networks, actors should be interlinked in one or more tripartite networks.}, author = {Nazir, F. and Takeda, H.}, booktitle = {IEEE International Symposium on Technology and Society}, doi = {10.1109/ISTAS.2008.4559785}, interhash = {7d3cb02c1c7774fe43e4303f0d3c37a4}, intrahash = {c3cca9801ab1e6d2598be1041c19618c}, isbn = {978-1-4244-1669-1}, month = jun, organization = {IEEE}, pages = {1--13}, title = {Extraction and analysis of tripartite relationships from Wikipedia}, url = {http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=4559785}, year = 2008 } @book{Hildebrand.2006, address = {Heidelberg}, author = {Hildebrand, Knut and Hofmann, Josefine}, interhash = {10758973fb39f4d87057329698ecf83c}, intrahash = {a62672e137133ee3df9f6b8205d6d3ec}, isbn = {3898643840}, publisher = {dpunkt-Verl.}, series = {HMD - Praxis der Wirtschaftsinformatik}, title = {Social Software: Einsatz- und Nutzungspotenziale, Web 2.0 im Kundenmanagement, Mobile Social Software, Wissensmanagement mit Wikis, Social Internet, Wikipedia in der Aus- und Weiterbildung, Mobile Communities}, volume = {43.2006,252}, year = 2006 } @book{Moller.2006, address = {Hannover}, author = {Möller, Erik}, edition = {2., erw. und aktualisierte Aufl.}, interhash = {a878c974c6ace8cd7b96840a0d3d8339}, intrahash = {02fc63ee866cb96eedba8b04ad55152b}, isbn = {3936931364}, publisher = {Heise}, series = {TelepolisMagazin der Netzkultur}, title = {Die heimliche Medienrevolution: Wie Weblogs, Wikis und freie Software die Welt verändern}, url = {http://www.sub.uni-hamburg.de/ebook/ebook.php?act=b&cid=7335 / http://deposit.ddb.de/cgi-bin/dokserv?id=2780980&prov=M&dok_var=1&dok_ext=htm}, year = 2006 } @book{berendt2008challenge, editor = {Berendt, Bettina and Glance, Natalie and Hotho, Andreas}, interhash = {ab9a3d6f27b2bc93cb8137a0f7988271}, intrahash = {50f6cd75018d7ee98f49c5ab4ef0faaf}, publisher = {Workshop at 18th Europ.

As they grow, wikis suffer from a number of problems (anarchical structure, large number of pages, aging navigation paths, etc.). We believe that semantic wikis can improve navigation and search. In SweetWiki we investigate the use of semantic web technologies to support and ease the lifecycle of the wiki. The very model of wikis was declaratively described: an OWL schema captures concepts such as WikiWord, wiki page, forward and backward link, author, etc. This ontology is then exploited by an embedded semantic search engine (Corese). In addition, SweetWiki integrates a standard WYSIWYG editor (Kupu) that we extended to support semantic annotation following the "social tagging" approach made popular by web sites such as flickr.com. When editing a page, the user can freely enter some keywords in an AJAX-powered textfield and an auto-completion mechanism proposes existing keywords by issuing SPARQL queries to identify existing concepts with compatible labels. Thus tagging is both easy (keyword-like) and motivating (real time display of the number of related pages) and concepts are collected as in folksonomies. To maintain and reengineer the folksonomy, we reused a web-based editor available in the underlying semantic web server to edit semantic web ontologies and annotations. Unlike in other wikis, pages are stored directly in XHTML ready to be served and semantic annotations are embedded in the pages themselves using RDF/A. If someone sends or copy a page, the annotations follow it, and if an application crawls the wiki site it can extract the metadata and reuse them.}, author = {Buffa, Michel and Crova, Gaël and Gandon, Fabien and Lecompte, Claire and Passeron, Jeremy}, booktitle = {Proceedings of the First Workshop on Semantic Wikis -- From Wiki To Semantics}, crossref = {SemWiki2006-proceedings}, editor = {V\"{o}lkel, Max and Schaffert, Sebastian}, interhash = {1c74dcb1a3394af9f9a61b8a9228d693}, intrahash = {76b6d7afdb3d4f4c19cb02a60c41bb0c}, month = {June}, owner = {voelkel}, publisher = {ESWC2006}, series = {Workshop on Semantic Wikis}, timestamp = {2006.06.14}, title = {SweetWiki : Semantic WEb Enabled Technologies in Wiki}, url = {http://semwiki.org/semwiki2006}, year = 2006 } @proceedings{SemWiki2006-proceedings, editor = {V\"{o}lkel, Max and Schaffert, Sebastian}, interhash = {25c4d07a674694805cd9bf759037ff4f}, intrahash = {6729d6637b54ea901e5a021153186f3b}, month = {June}, owner = {voelkel}, publisher = {ESWC2006}, series = {Workshop on Semantic Wikis}, timestamp = {2006.06.14}, title = {Proceedings of the First Workshop on Semantic Wikis -- From Wiki To Semantics}, url = {http://semwiki.org/semwiki2006}, year = 2006 } @inproceedings{Schaffert:2006:LwSW, abstract = {The knowledge society requires life-long learning and flexible learning environments that allow learners to learn whenever they have time, whereever they are, and according to their own needs and background knowledge.
