Abstract : This paper addresses the problem of information evaluation for Intelligence. Starting from NATO recommendations for assessing information, we propose a semantic-based model to evaluate information. We also define a semi-automatic evaluation process in which an ontology is used to detect similar items of information. Semantically similar items are then presented to an operator in charge to estimate their correlations. Items of information are electronic documents exploited for intelligence purposes and they are considered in a broader sense with respect to their form structured files or free-form text and with their content description of images of video scenes, HUMINT reports. Linguistic variance, an inherent feature of textual data, can also be handled by using the ontology, while the human intervention during the evaluation process ensures a good quality outcome. Finally we show that this process is compliant with NATO recommendations, while going beyond their limitations
