When building a social network for performing an SNAanalysis, an initial process of data gathering is achieved in order to extract the characteristics of theindividuals and their relationships. This is usually done by completing a questionnaire containingdifferent types of questions that will be later used to obtain the SNA measures needed to perform thestudy. There are, then, a great number of different possible network-generating questions and alsomany possibilities for mapping the responses to the corresponding characteristics and relationships.Many variations may be introduced into these questions (the way they are posed, the weightsgiven to each of the responses, etc.) that may have an effect on the resulting networks. All thesedifferent variations are difficult to achieve manually, because the process is time-consuming anderror-prone. The tool described in this paper uses semantic knowledge representation techniques inorder to facilitate this kind of sensitivity studies. The base of the tool is a conceptual structure, called“ontology” that is able to represent the different concepts and their definitions. The tool is comparedto other similar ones, and the advantages of the approach are highlighted, giving some particularexamples from an ongoing SNA study about alcohol consumption habits in adolescents.
