Although the exploitation of temporal information in retrieval and organization tasks has a long tradition, content-based approaches have not been fully explored for Twitter and researchers lack of sucient Corpus annotated with temporal information. In this paper, we propose a temporal document annotation model based on Formal Concept Analysis theory for Twitter domain. The tweets attributes dening the temporal context are the temporal expressions, the events and their types. It is also proposed a calendar especially suited to the phenomena of commemoration of anniversaries and dates in Twitter: The Social-Imaginary Calen- dar. The Corpus used to the experiments is a subset of the RepLab2013 collection. A detailed description of its temporal aspects is provided.
