This article develops and tests an expectancy model that predicts specific conditions under which collective benefits can be made to converge with private ones, thus resolving communication dilemmas and motivating voluntary contributions to a collectively shared database. In the model, motivation is a multiplicative function of individual-level attitudes and beliefs: (a) organizational commitment; (b) organizational instrumentality, an instrumentality that links successful collective information sharing to broader organizational gain; (c) connective efficacy, an expectation that information contributed to the database will reach other members of the collective; and (d) information self-efficacy, the self-perceived value of a contributor's information to other database users. The model was tested by a survey administered to members of an intact work team using a discretionary database. The multiplicative model was significant and explained sizeable amounts of variance in the motivation to contribute discretionary information. Implications for theory and practice are discussed. The model can be readily extended to predict information sharing by means of other communication media.

This is explained by the fact that this kind of information exchange represents a social dilemma. This article applies critical concepts of dilemma theory to the interpretation of database information exchange as a social dilemma and tests their effects experimentally. A prestudy with the experimental task ensures that people perceive database information exchange as a social dilemma, and two experiments investigate three factors influencing this dilemma: (a) a person's meta-knowledge about the importance of his information for the other group members, (b) a use-related bonus system that rewards contribution of important information, and (c) costs incurred by the contribution of important or less important information. As dependent variables people's contribution behavior as well as their subjective perception of the dilemma structure are considered. The results show that metaknowledge enhances the quality of contributions, especially in combination with a use-related bonus system, whereas increased contribution costs influence the contribution behavior negatively.

The case-based task management (CBTM) system is based on the transduction of execution protocols, so-called cases; and the pattern-based task management (PBTM) system is based on task patterns that are derived from cases but yield more abstract information. As user motivation to contribute to a collaborative task management system is a crucial factor for its success, we consider the different motivational requirements of CBTM and PBTM from a psychological point of view. Based on experimental findings about different factors that have been shown to enhance people's motivation to contribute their knowledge to a shared pool, we compare the two approaches and assess which one is more appropriate with respect to motivation. http://www.bibsonomy.org/bibtex/2f0361e985a26b51edadccec8d7c0b2f6/uvrissuvriss2007-09-26T10:36:02+02:00PIM haystack <span style="color:#555555;">Dennis <a href="http://www.bibsonomy.org/author/Quan">Quan</a> and David <a href="http://www.bibsonomy.org/author/Huynh">Huynh</a> and David R. <a href="http://www.bibsonomy.org/author/Karger">Karger</a> </span><em>Proceedings of ISWC, </em>(<em>2003</em>)Wed Sep 26 10:36:02 CEST 2007Proceedings of ISWCHaystack: A Platform for Authoring End User Semantic Web Applications2003PIM haystack The Semantic Web promises to open innumerable opportunities for automation and information retrieval by standardizing the protocols for metadata exchange. However, just as the success of the World Wide Web can be attributed to the ease of use and ubiquity of Web browsers, we believe that the unfolding of the Semantic Web vision depends on users getting powerful but easy-to-use tools for managing their information. But unlike HTML, which can be easily edited in any text editor, RDF is more complicated to author and does not have an obvious presentation mechanism. Previous work has concentrated on the ideas of generic RDF graph visualization and RDF Schema-based form generation. In this paper, we present a comprehensive platform for constructing end user applications that create, manipulate, and visualize arbitrary RDFencoded information, adding another layer to the abstraction cake. We discuss a programming environment specifically designed for manipulating RDF and introduce user interface concepts on top that allow the developer to quickly assemble applications that are based on RDF data models. Also, because user interface specifications and program logic are themselves describable in RDF, applications built upon our framework enjoy properties such as network updatability, extensibility, and end user customizability—all desirable characteristics in the spirit of the Semantic Web.Haystack: A Customizable General-Purpose Information Management Tool for End Users of Semistructured Data (ResearchIndex)http://www.bibsonomy.org/bibtex/2055721cf7a510a347d71df4e337049db/uvrissuvriss2007-09-26T10:34:39+02:002005 PIM <span style="color:#555555;">David R. <a href="http://www.bibsonomy.org/author/Karger">Karger</a> and Karun <a href="http://www.bibsonomy.org/author/Bakshi">Bakshi</a> and David <a href="http://www.bibsonomy.org/author/Huynh">Huynh</a> and Dennis <a href="http://www.bibsonomy.org/author/Quan">Quan</a> and Vineet <a href="http://www.bibsonomy.org/author/Sinha">Sinha</a> </span><em>Proceedings of of CIDR 2005, </em>(<em>2005</em>)Wed Sep 26 10:34:39 CEST 2007Proceedings of of CIDR 2005Haystack: A Customizable General-Purpose Information Management Tool for End Users of Semistructured Data20052005 PIM http://www.bibsonomy.org/bibtex/2107849390258ecf22fd85500e3947c42/uvrissuvriss2007-09-26T10:17:52+02:00PIM semantic_desktop <span style="color:#555555;">Leo <a href="http://www.bibsonomy.org/author/Sauermann">Sauermann</a> </span><em>Proceedings of the I-KNOW 2005. 5th International Conference on Knowledge Management, </em><em>page294 - 301. </em>(<em>2005</em>)Wed Sep 26 10:17:52 CEST 2007Proceedings of the I-KNOW 2005. 5th International Conference on Knowledge Management294 - 301The Semantic Desktop - a Basis for Personal Knowledge Management2005PIM semantic_desktop iMeMexhttp://www.bibsonomy.org/bibtex/2edc145b72c97e045ee146d288e548298/uvrissuvriss2007-09-26T10:09:13+02:00iMeMex PIM 2005 <span style="color:#555555;">Jens-Peter <a href="http://www.bibsonomy.org/author/Dittrich">Dittrich</a> and Marcos Antonio Vaz <a href="http://www.bibsonomy.org/author/Salles">Salles</a> and Donald <a href="http://www.bibsonomy.org/author/Kossmann">Kossmann</a> and Lukas <a href="http://www.bibsonomy.org/author/Blunschi">Blunschi</a> </span><em>VLDB '05: Proceedings of the 31st international conference on Very large data bases, </em><em>page1306--1309. </em><em>VLDB Endowment, </em>(<em>2005</em>)Wed Sep 26 10:09:13 CEST 2007VLDB '05: Proceedings of the 31st international conference on Very large data bases1306--1309iMeMex: escapes from the personal information jungle2005iMeMex PIM 2005 Modern computer work stations provide thousands of applications that store data in > 100.000 files on the file system of the underlying OS. To handle these files data processing logic is reinvented inside each application. This results in a jungle of data processing solutions and a jungle of data and file formats. For a user, it is extremely hard to manage information in this jungle. Most of all it is impossible to use data distributed among different files and formats for combined queries, e.g., join and union operations. To solve the problems arising from file based data management, we present a software system called iMeMex as a unified solution to personal information management and integration. iMeMex is designed to integrate seamlessly into existing operating systems like Windows, Linux and Mac OS X. Our system enables existing applications to gradually dispose file based storage. By using iMeMex modern operating systems are enabled to make use of sophisticated DBMS, IR and data integration technologies. The seamless integration of iMeMex into existing operating systems enables new applications that provide concepts of data storage and analysis unseen before.proceedings of the 1st semantic desktop workshophttp://www.bibsonomy.org/bibtex/25bc7a439f68d2bcef066aaab91a20861/uvrissuvriss2007-09-26T09:54:17+02:00semantic_desktop PIM <span style="color:#555555;">Huiyong <a href="http://www.bibsonomy.org/author/Xiao">Xiao</a> and Isabel F. <a href="http://www.bibsonomy.org/author/Cruz">Cruz</a> </span><em>Proc. of Semantic Desktop Workshop at the ISWC, Galway, Ireland, November 6, </em><em>175, </em><em>November2005. </em>Wed Sep 26 09:54:17 CEST 2007Proc. of Semantic Desktop Workshop at the ISWC, Galway, Ireland, November 6November A Multi-Ontology Approach for Personal Information Management 1752005semantic_desktop PIM Reference reconciliation in complex information spaceshttp://www.bibsonomy.org/bibtex/2b20229716aa3b0076ce2f7a44c8fa0f3/uvrissuvriss2007-09-26T09:47:52+02:002005 PIM SIMEX <span style="color:#555555;">Xin <a href="http://www.bibsonomy.org/author/Dong">Dong</a> and Alon <a href="http://www.bibsonomy.org/author/Halevy">Halevy</a> and Jayant <a href="http://www.bibsonomy.org/author/Madhavan">Madhavan</a> </span><em>SIGMOD '05: Proceedings of the 2005 ACM SIGMOD international conference on Management of data, </em><em>page85--96. </em><em>New York, NY, USA, </em><em>ACM Press, </em>(<em>2005</em>)Wed Sep 26 09:47:52 CEST 2007New York, NY, USASIGMOD '05: Proceedings of the 2005 ACM SIGMOD international conference on Management of data85--96Reference reconciliation in complex information spaces20052005 PIM SIMEX Reference reconciliation is the problem of identifying when different references (i.e., sets of attribute values) in a dataset correspond to the same real-world entity. Most previous literature assumed references to a single class that had a fair number of attributes (e.g., research publications). We consider complex information spaces: our references belong to multiple related classes and each reference may have very few attribute values. A prime example of such a space is Personal Information Management, where the goal is to provide a coherent view of all the information on one's desktop.Our reconciliation algorithm has three principal features. First, we exploit the associations between references to design new methods for reference comparison. Second, we propagate information between reconciliation decisions to accumulate positive and negative evidences. Third, we gradually enrich references by merging attribute values. Our experiments show that (1) we considerably improve precision and recall over standard methods on a diverse set of personal information datasets, and (2) there are advantages to using our algorithm even on a standard citation dataset benchmark.http://www.bibsonomy.org/bibtex/2212ebf12ad3099589e1079ebeebc5fe3/uvrissuvriss2007-09-26T09:32:30+02:00SEMEX 2005 PIM <span style="color:#555555;">Xin <a href="http://www.bibsonomy.org/author/Dong">Dong</a> and Alon Y. <a href="http://www.bibsonomy.org/author/Halevy">Halevy</a> </span><em>CIDR, </em><em>page119-130. </em>(<em>2005</em>)Wed Sep 26 09:32:30 CEST 2007CIDR119-130A Platform for Personal Information Management and Integration2005SEMEX 2005 PIM dblphttp://www.bibsonomy.org/bibtex/2899785a20995a99c05c97bab06f2a301/uvrissuvriss2007-09-25T19:52:40+02:00activities 2006 <span style="color:#555555;">Sibel <a href="http://www.bibsonomy.org/author/Adali">Adali</a> and Shawn <a href="http://www.bibsonomy.org/author/Pearce">Pearce</a> and Maria Luisa <a href="http://www.bibsonomy.org/author/Sapino">Sapino</a> </span><em>ICDE Workshops, </em><em>page103. </em><em>IEEE Computer Society, </em>(<em>2006</em>)Tue Sep 25 19:52:40 CEST 2007ICDE Workshopsconf/icde/2006w103On Querying and Exploring Activities on a User's Desktop.2006activities 2006 http://www.bibsonomy.org/bibtex/2553bcaa73c3109c3ce21ff075762069f/uvrissuvriss2007-09-19T15:58:10+02:00SWS web_service 2006 <span style="color:#555555;">E. <a href="http://www.bibsonomy.org/author/Michael Maximilien">Michael Maximilien</a> </span><em>scc</em>(<em>2006</em>)Wed Sep 19 15:58:10 CEST 2007Los Alamitos, CA, USAscc11-18Semantic Web Services for Human Activit02006SWS web_service 2006 activity patterns WebServiceshttp://www.bibsonomy.org/bibtex/2f17dfd3aa603ee5d6b41422957ab653e/uvrissuvriss2007-09-19T15:39:32+02:00activity pattern UAM <span style="color:#555555;">A. <a href="http://www.bibsonomy.org/author/Cozzi">Cozzi</a> and S. <a href="http://www.bibsonomy.org/author/Farrell">Farrell</a> and T. <a href="http://www.bibsonomy.org/author/Lau">Lau</a> and B.

However, beside consistency checking, current ontology engineering tools provide only basic functionalities for analyzing ontologies. Since ontologies can be considered as (labeled, directed) graphs, graph analysis techniques are a suitable answer for this need. Graph analysis has been performed by sociologists for over 60 years, and resulted in the vivid research area of Social Network Analysis (SNA). While social network structures in general currently receive high attention in the Semantic Web community, there are only very few SNA applications up to now, and virtually none for analyzing the structure of ontologies. We illustrate in this paper the benefits of applying SNA to ontologies and the Semantic Web, and discuss which research topics arise on the edge between the two areas. In particular, we discuss how different notions of centrality describe the core content and structure of an ontology. From the rather simple notion of degree centrality over betweenness centrality to the more complex eigenvector centrality based on Hermitian matrices, we illustrate the insights these measures provide on two ontologies, which are different in purpose, scope, and size.http://www.bibsonomy.org/bibtex/242f436b527e5d2f144c743d0ee41dec9/uvrissuvriss2007-08-13T18:26:57+02:00project context knowledge_management personalization EPOS <span style="color:#555555;">Leo <a href="http://www.bibsonomy.org/author/Sauermann">Sauermann</a> and Andreas <a href="http://www.bibsonomy.org/author/Dengel">Dengel</a> and Ludger van <a href="http://www.bibsonomy.org/author/Elst">Elst</a> and Andreas <a href="http://www.bibsonomy.org/author/Lauer">Lauer</a> and Heiko <a href="http://www.bibsonomy.org/author/Maus">Maus</a> and Sven <a href="http://www.bibsonomy.org/author/Schwarz">Schwarz</a> </span><em>Proceedings of the Semantic Web Personalization Workshop at the ESWC, </em><em>page42 - 52. </em>(<em>2006</em>)Mon Aug 13 18:26:57 CEST 2007Proceedings of the Semantic Web Personalization Workshop at the ESWC42 - 52Personalization in the EPOS project2006project context knowledge_management personalization EPOS In this work we present the results of the EPOS project with regard to the needs of personalization in the Semantic Web. Focus of this work is the subjective view of an individual person, expressed in a Personal Information Model (PIMO). It is matched both with personal resources (files, e-mails, and websites) of the user and organizational knowledge (ontologies). A user observation component gathers actions of the user to calculate the current context with regards to current goals and matching elements in the user's PIMO. Combined, the representation of the user's stored information and the current context provide a thorough representation of the user. Desktop applications can use this representation to provide personalized services. Three special purpose applications were implemented: a search engine, a context-sensitive assistant, and a tool for filing new information. An evaluation of this approach showed that it increases productivity and indeed reflects the subjective view of users. Also, the approach satisfies most of the requirements of an Adaptive Educational Hypermedia System AEHS.
