Proceedings of the 2012 ASE International Conference on Social Informatics, SocialInformatics 2012 English 2013 gSocial computingh is a keyword in contemporary society. However, if we ask anew what the term social computing means, we realize that its definition, meaning and modeling have not necessarily been clarified. This paper first investigates when questions are raised about gsocial computing.h We find that the oldest Wikipedia article on social computing was written on January 21, 2005. However, it is found that a major rewrite was done on October 17, 2007, which caused a great change in its definition. It seems that the reason for this change is the idea of collective intelligence that has been popularized in James Surowiecki's book, The Wisdom of Crowds. In order to examine how the concept of social computing is accepted by and has infiltrated the web society, we performed an analysis of the search engine results page (SERP) using Google, specifying the search keyword as gsocial computing.h This paper investigates a formal model of social computing, which is described in contrast with the traditional computing scheme. Based on this model, we investigate the relationship between social computing and computer science, and we conclude that the Wikipedia article on social computing that states gsocial computing is a general term for an area of computer science ch is inaccurate. 0 0
Developing WikiBOK: A Wiki-based BOK formulation-aid system Lecture Notes in Electrical Engineering English 2012 The design and implementation of WikiBOK, a Wiki-based body of knowledge (BOK) formulation-aid system, is investigated in this paper. In contrast to formulating a BOK for a matured discipline such as computer science, BOK formulation for a new discipline such as social informatics needs a "bottom-up" approach because academics in a new discipline cannot draw its entire figure par avance. Therefore, an open collaboration approach based on the collective intelligence concept seems promising. WikiBOK is under development as part of our project based on BOK+, which is a novel BOK formulation principle for new disciplines. It uses Semantic MediaWiki (SMW) to facilitate its fundamental functions. To support a rich graphical user interface for WikiBOKers, a a graph visualization software, Graphviz, is adopted. SMW is enhanced to work in conjunction with Graphviz. Because edit conflicts occur when WikiBOKers collaborate, a resolution principle is investigated to resolve BOK tree edit conflicts. 0 0

Proceedings - 2012 ASE/IEEE International Conference on Privacy, Security, Risk and Trust and 2012 ASE/IEEE International Conference on Social Computing, SocialCom/PASSAT 2012 English 2012 A body of knowledge (BOK) of an academic field is an indispensable aid not only to people's understanding of the entirety of a targeted academic field, but also to designing a perfect curriculum of that field for educational purposes. However, in contrast to a BOK for a mature discipline such as computer science, the formulation of a BOK for a new discipline, such as social informatics, life science, and sustainability science, is difficult because academics in such a new discipline cannot present it in its entirety par advance. Therefore, a bottom-up and open collaborative approach based on collective intelligence seems promising, and contrasts strongly with the traditional style in which a BOK is formulated: by the authorities in the field in a top-down manner. WikiBOK is a wiki-based body of knowledge (BOK) formulation-aid system for new disciplines. It is developed based on BOK+, which is a novel BOK formulation principle for new disciplines that enables us to construct a BOK in a bottom-up manner. As its name indicates, WikiBOK uses Semantic Media Wiki (SMW) to facilitate its fundamental functions. A rich graphical user interface is provided using open source graph visualization software. The main objective of this paper is to illustrate how edit conflicts are resolved in WikiBOK. Needless to say, edit conflicts are unavoidable when WikiBOKers collaborate to formulate a BOK-tree. A WikiBOK edit conflict resolution principle is shown, and the WikiBOK Edit Conflict Resolver is implemented based on this principle. Social Informatics BOK (SIBOK) is under construction using WikiBOK. 0 0

Semantic MediaWiki (SMW)
WikiSym 2010 English 2010 This paper describes a wiki-based collective intelligence approach to provide a system environment that enables users to formulate a body of knowledge (BOK) for a new discipline, such as social informatics. When the targeted discipline is mature, for example, computer science, its BOK can be straightforwardly formulated by a task force using a top-down approach. However, in the case of a new discipline, it is presumed that nobody has a comprehensive understanding of it; therefore, the formulation of BOK in such a field can be carried out using a bottom-up approach. In other words, a collective intelligence approach supporting such work seems promising. This paper proposes the BOK+ which is a novel BOK formulation principle for new disciplines. To realize this principle, the BOK Constructor is designed and prototyped where Semantic MediaWiki (SMW) is used to provide its basic functions. The BOK Constructor consists of a BOK Editor, SMW, Uploader, and BOK Miner. Most of the fundamental functions of the BOK Constructor, with the exception of the BOK Miner, were implemented. We validated that the BOK Constructor serves its intended purpose. 0 0
