Etiquetagem e folksonomia: uma análise sob a óptica dos processos de organização e recuperação da informação na web

This research studies tagging and folksonomy related to the process of organization and re-trieval of information in the web. Some elements that must be in these processes are defined: index, knowledge organization, users and applications, allowing the validation of tagging and folksonomy in this context. It uses the methodology of bibliographic review, user study and exploratory and descriptive analysis of websites. A bibliographic research about index is presented, including cognitive index, user-centered index, fiction index, image index and democratic or collaborative index. It identifies elements presented in those kinds of indexes that share characteristics with the process of tagging, making possible a parallel between both practices. The same methodology is used to study folksonomy under the view of the approaches in knowledge organization in with folksonomy finds basis to be analyzed: user-based, cognitive, social and information retrieve approaches. This chapter highlights positive and negative aspects of folksonomy as a knowledge representation scheme and analyzes also how this structure can reflect knowledge or not. The research applies a study of the users that participate of the process of tagging, so as to find out the motivations for tagging. It analyses how this motivations are related to the objectives of organization and retrieval of information. The last chapter verifies the application of tagging and folksonomy in the web. It describes sites that use such systems relating with the process of information organization and retrieval. The research concludes that, despite of some limitations, tagging and folksonomy have enough characteristics to be considered a valid model for organization and retrieval of information in the web, with higher or lower potential, depending on the nature of the site in which its inserted and of the information package with which it’s related
