Semantic markup of information on sanitation initiatives in informal settlements
(2006) Obonyo, Esther; Omenya, Alfred
The fundamental problem with the ‘traditional’ Web is: information is designed for human consumption and even with the evolution of powerful search engines, information filtering still remains a task that requires significant human involvement. Consequently, any application that is designed to use Web-enabled technologies will eventually encounter problems related to ‘information overload’ and ‘digital anarchy’ (the latter problem emanates from lack of interoperability across systems especially in different organisations). This paper describes a conceptual framework that addresses these issues using emerging Semantic Web Technologies. The framework will focus on demonstrating the potential benefits of using semantic markups and ontologies to augment Web content for Sanitation initiatives in informal settlements using the experience in Nairobi as a test case. It will address problems arising from the sheer scale and diversity of data on sustainable sanitation practice through the use of the Semantic Web technologies. The conceptual framework presented in this paper will be further defined through an iteration of workshops with the stakeholders and expanded into a platform for semantically matching a controlled taxonomy for Sustainable Sanitation for informal settlements.
