Expert services, such as taxonomic identification, are required in many biodiversity management activities, yet these services remain inaccessible to poor communities, such as small-scale farmers. The aim of this research was to combine ontology and crowdsourcing technologies to provide taxonomic services to such communities. The study used a design science research (DSR) approach to develop the conceptual architecture. The DSR approach generates knowledge through building and evaluation of novel artefacts. The research instantiated the architecture through the development of a platform for experts and farmers to share knowledge on fruit flies. The platform is intended to support rural fruit farmers in Kenya with control and management of fruit flies. Expert knowledge about fruit flies is captured in an ontology that is integrated into the platform. The non-expert citizen participation includes harnessing crowdsourcing technologies to assist with organism identification. An evaluation of the architecture was done through an experiment of fruit fly identification using the platform. The results showed that the crowds, supported by an ontology of expert knowledge, could identify most samples to species level and in some cases to sub-family level. The conceptual architecture may guide and enable creation of citizen-expert knowledge exchange applications, which may alleviate the taxonomic impediment, as well as allow poor citizens access to expert knowledge. Such a conceptual architecture may also enable the implementation of systems that allow non-experts to participate in sharing of knowledge, thus providing opportunity for the evolution of comprehensive biodiversity knowledge systems.","PeriodicalId":105861,"journal":{"name":"South African Journal of Information and Communication","volume":"236 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114263365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The creative economy, based to a significant extent on ideas rather than physical capital, offers new, high-growth opportunities for developing countries. The author of this article led a WIPOcommissioned study (Belete & Tadesse, 2014) of the economic contribution of the creative industries in Ethiopia. That study quantified the contribution of “copyright industries” to the country’s economy, and showed the sector’s great potential to contribute to sustainable development in the country. Alongside the vast opportunities offered by the creative industries, that earlier study also found a number of corresponding challenges that needed to be addressed by Ethiopian policymakers. In this article, the author provides a framework for understanding the policy issues at play in the Ethiopian creative industries sector and then brings that framework to bear on the findings of his earlier study (Belete & Tadesse, 2014). The result is a set of proposed policy measures that the author determines are-necessary for optimal support of Ethiopia’s creative economy.","PeriodicalId":105861,"journal":{"name":"South African Journal of Information and Communication","volume":"202 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133490476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analytical framework used the concepts of social networks and online social networks (OSNs); social network ties; social capital and online social capital; knowledge and novel knowledge; communities of practice (CoPs); problem solving; and innovation. Quantitative methods were used, involving analysis of data collected from a sample of LinkedIn members residing in South Africa. It was apparent from the analysis that knowledge acquired on LinkedIn, relating to a member’s subject matter proficiency, benefited the member's firm. It was also evident that this knowledge contributed to the firm’s problem solving process. The data did not, however, confirm or refute the proposition that knowledge acquired by members on LinkedIn contributed to their firms’ innovation. An overall observation from the data was that members did not perceive substantial value from the knowledge available on LinkedIn. The authors therefore recommend that greater initiative be taken by members and firms to adopt open networking approaches, using online social networks such as LinkedIn, starting with attitudinal and policy considerations on the part of firms.","PeriodicalId":105861,"journal":{"name":"South African Journal of Information and Communication","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125419756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
