RESUMO

Social Network Services (SNSs) may represent an opportunity for not digitally literate people to effectively familiarize themselves with information and communication technologies. For that, these systems should provide inclusive access, creating situations where users cultural diversity is respected and their difficulties minimized. SNSs with resources that promote access for all, including those in the margin of the digital culture can be defined as Inclusive Social Network Services (ISNs). In these networks, ordinary people must have the possibility of easily recovering correct information, which makes sense to them. In this context, the objective of this work is to investigate the conception of an inclusive search mechanism more adequate to the ISN concept, which may propitiate more meaningful and personalized search results. Although the use of search mechanisms has been the main alternative to access information in the Web, such mechanisms are still built mainly through lexic-syntactical processing of information, resulting in barriers for many users. The use of semantic search techniques driven by Semantic Web (SW) technologies presents new possibilities for the highlighted problem, but it is still grounded in limited paradigms and methods for the representation of the social knowledge. In order to develop an inclusive search mechanism in ISN it is necessary to "interpret" the meanings shared by people. Approaches and methods that allow capturing the social and cultural aspects from the social network, such as their colloquial language and semantic relations, are necessary for that. Therefore, the inclusive search mechanism proposed in this work adopts an ontology-based solution that is based on a novel approach for the design of Web ontologies. Such approach is grounded on Organizational Semiotics (OS) concepts and methods, combined with SW technologies. The conception of this solution was inspired in experimental results with real users on search activities in an ISN system. This may enable novel ontology-based search strategies, and consequently generates the possibility of promoting the participatory and universal access to knowledge.
