This work aims at proposing a knowledge-model based in the application of a systemic methodology for ontology building about the official recognition for the victims of forced displacement in the Colombian case. In this human and social science circumstance, the official policy of restitution is the way as the Estate is reestablishing the victims’ rights, particularly for land restitution problematic. We expose the relevance of a qualitative analysis based on netnography as another and useful knowledge source together with the application of a methodology for ontology construction (SMOL). In addition to the tool used for ontology building and enrichment, we have applied some common tools (NVIVO & GEPHI) for qualitative analysis incrementally during this knowledge-discovering process. Consequently, the land restitution domain representation has been reached from different knowledge sources, such as journals reviews, other previous domain-ontologies (SIDEON), some interviews for affected by displacements and the derived knowledge available on social networks (Twitter posts).
