Information fusion includes the integration of data for situational understanding. As a situation unfolds, maintaining awareness depends on diverse collections of data. In complex and dynamic scenarios, human operators face the difficult task of choosing which data to collect next. Hence, there is a need for multilayered fusion processes that exploit multiple models and levels of abstraction for understanding and sense-making Data collection has its roots in sensor management; however, there is an analogous need for data management - such as the incorporation of public domain data. Mature sensor management includes methods to utilize platform, sensor, and scene modeling so as to guide the user for future data collection. Additionally, these physics-based models could be a method to guide human-derived information models. Using the Data Fusion Information Group Model (DFIG), we develop an equivalent method for diffusion control. This paper focuses on recent techniques in statistical relational learning (SRL), Markov logic networks (MLN), and ontologies to support the control diffusion of data sensing to answer user queries.
