This model paves the way for semantic annotation of implicit, well-defined workflows, thus making them explicit and exposing the missing information in a machine processable way. Grounding this work within the Social Semantic Desktop [1] via appropriate ontologies means that this information can be exploited for the benefit of the user. This will have a direct impact on their personal information management - given email is not just a major channel of data exchange between desktops, but it also serves as a virtual working environment where people collaborate. Thus the presented workflow model will have a concrete manifestation in the creation, organization and exchange of semantic desktop data.}, added-at = {2010-08-30T14:19:40.000+0200}, author = {Decker, Simon Scerri Siegfried Handschuh Stefan}, biburl = {http://www.bibsonomy.org/bibtex/27d84d78ead292dc2f5a0365c34d386b7/nepomuk}, interhash = {a9b86c0d346699fa4fcc691642bfcd08}, intrahash = {7d84d78ead292dc2f5a0365c34d386b7}, keywords = {information outlook semantic desktop scerri interface speech personal email social semanta from:irrecs conversation simon act user management add-in}, timestamp = {2010-08-30T14:19:40.000+0200}, title = {Semantic Email as a Communication Medium for the Social Semantic Desktop}, year = 2008 } @inproceedings{Jaeschke2008logsonomy, abstract = {In social bookmarking systems users describe bookmarks by keywords called tags.

The structure behind these social systems, called folksonomies, can be viewed as a tripartite hypergraph of user, tag and resource nodes. This underlying network shows specific structural properties that explain its growth and the possibility of serendipitous exploration. Today’s search engines represent the gateway to retrieve information from the World Wide Web. Short queries typically consisting of two to three words describe a user’s information need. In response to the displayed results of the search engine, users click on the links of the result page as they expect the answer to be of relevance. This clickdata can be represented as a folksonomy in which queries are descriptions of clicked URLs. The resulting network structure, which we will term logsonomy is very similar to the one of folksonomies. In order to find out about its properties, we analyze the topological characteristics of the tripartite hypergraph of queries, users and bookmarks on a large snapshot of del.icio.us and on query logs of two large search engines. All of the three datasets show small world properties. The tagging behavior of users, which is explained by preferential attachment of the tags in social bookmark systems, is reflected in the distribution of single query words in search engines. We can conclude that the clicking behaviour of search engine users based on the displayed search results and the tagging behaviour of social bookmarking users is driven by similar dynamics.}, added-at = {2009-05-13T09:36:02.000+0200}, address = {New York, NY, USA}, author = {Krause, Beate and Jäschke, Robert and Hotho, Andreas and Stumme, Gerd}, biburl = {http://www.bibsonomy.org/bibtex/2e64d14f3207766f4afc65983fa759ffe/nepomuk}, booktitle = {HT '08: Proceedings of the Nineteenth ACM Conference on Hypertext and Hypermedia}, doi = {http://doi.acm.org/10.1145/1379092.1379123}, interhash = {6d34ea1823d95b9dbf37d4db4d125d2a}, intrahash = {e64d14f3207766f4afc65983fa759ffe}, isbn = {978-1-59593-985-2}, keywords = {2008 analysis engine from:jaeschke information l3s logsonomy myown network retrieval search social wp5}, location = {Pittsburgh, PA, USA}, pages = {157--166}, publisher = {ACM}, timestamp = {2009-05-13T09:36:02.000+0200}, title = {Logsonomy - Social Information Retrieval with Logdata}, url = {http://portal.acm.org/citation.cfm?id=1379092.1379123&coll=ACM&dl=ACM&type=series&idx=SERIES399&part=series&WantType=Journals&title=Proceedings%20of%20the%20nineteenth%20ACM%20conference%20on%20Hypertext%20and%20hypermedia}, vgwort = {17}, year = 2008 } @inproceedings{Scerri2008semanticemail, abstract = {In this paper we provide a summary of work that has been pursued in the area of Semantic Email, with a particular focus on our work in the area.

Here we also generate text in the CL from an existing ontology using template-based (or shallow) Natural Language Generation (NLG). The text generator and the CLOnE authoring process combine to form a RoundTrip Ontology Authoring environment: one can start with an existing imported ontology or one originally produced using CLOnE, (re)produce the Controlled Language, modify or edit the text as required and then turn the text back into the ontology in the CLOnE environment. Building on previous methodology we undertook an evaluation, comparing the RoundTrip Ontology Authoring process with a well-known ontology editor; where previous work required a CL reference manual with several examples in order to use the controlled language, the use of NLG reduces this learning curve for users and improves on existing results for basic ontology editing tasks.}, added-at = {2009-03-25T15:51:00.000+0100}, author = {Davis, Brian and Iqbal, Ahmad and Funk, Adam and Tablan, Valentin and Bontcheva, Kalina and Cunningham, Hamish and Handschuh, Siegfried}, biburl = {http://www.bibsonomy.org/bibtex/268c730408ca714d95aabcfc2313ab69d/nepomuk}, citeulike-article-id = {4039710}, doi = {http://dx.doi.org/10.1007/978-3-540-88564-1\_4}, interhash = {1ac5be1019d857bdb2e6acd024239858}, intrahash = {68c730408ca714d95aabcfc2313ab69d}, journal = {The Semantic Web - ISWC 2008}, keywords = {authoring controlledLanguage from:siggi language ontology roundtrip smilegroup}, pages = {50--65}, posted-at = {2009-02-12 17:43:48}, priority = {2}, timestamp = {2009-03-25T15:51:00.000+0100}, title = {RoundTrip Ontology Authoring}, url = {http://dx.doi.org/10.1007/978-3-540-88564-1\_4}, year = 2008 } @inproceedings{4314, added-at = {2009-01-26T11:29:43.000+0100}, author = {Papailiou, Niki and Christidis, Costas and Apostolou, Dimitris and Mentzas, Gregoris and Gudjonsdottir, Rosa}, biburl = {http://www.bibsonomy.org/bibtex/2b8945d730e4056d6d354459347a8a576/nepomuk}, booktitle = {Collaboration and the Knowledge Economy: issues, Applications and Case Studies}, editor = {Cunnigham, O. and Cunnigham, M.}, interhash = {85f010b222dd2f7643ce4f12cf44b17c}, intrahash = {b8945d730e4056d6d354459347a8a576}, keywords = {ICCS KTH WP9000 from:dapost nepomuk}, timestamp = {2009-01-26T11:29:43.000+0100}, title = {Personal and Group Knowledge Management with the Social Semantic Desktop }, year = 2008 } @inproceedings{tetradio1, abstract = {This paper seeks to review the role of social networks in knowledge management in the business context of consulting firms.
