Abstract(s)
As tags podem ser utilizadas com diferentes propósitos, entre os quais organizar os recursos para fins pessoais e partilhar informação potencialmente relevante com outros utilizadores.
Este trabalho conjuga diversas Ôreas de conhecimento e explora a utilização de tags, debruçando-se numa categoria em particular que engloba as tags de opinião. Estas podem ser usadas para expressar sentimentos ou opiniões sobre os recursos.
Foram realizadas anÔlises sobre a utilização de tags na loja online Amazon. Recolhida uma amostra de dados, as tags foram classificadas e analisadas segundo diversos aspectos, inclusive quanto à sua polaridade.
AlĆ©m da atribuição de tags, na Amazon Ć© possĆvel atribuir pontuaƧƵes (de 1 a 5) aos recursos. Neste trabalho compararam-se ainda as duas formas referidas de classificação de recursos, verificando a existĆŖncia de alguma correspondĆŖncia entre ambas, com significado estatĆstico.
Adicionalmente, foi desenvolvido um classificador semi-automĆ”tico que tem como objectivo classificar as tags atribuĆdas aos recursos para proporcionar uma classificação rĆ”pida e eficiente da polaridade das tags que considera tambĆ©m a informação disponĆvel sobre os recursos durante o processo.

This work combines several knowledge areas and explores the use of tags, in particular the opinion tags. These can be used to express feelings or opinions about the resources. Analyses were performed on the use of tags in the Amazon online store. After selecting a data sample, the tags were classified and analyzed according to various aspects, including their polarity. In addition to the allocation of tags in Amazon, scores (1-5) can be assigned to resources. This work also compared the two mentioned resource classification forms, checking for any correspondence between them, with a statistical significance. Additionally, we developed a semi-automatic classifier which aims to classify the tags assigned to resources to provide a fast and efficient classification of the polarity of the tags that also considers the available information on the resources during the process.
