This document discusses strategies for horizontally integrating warfighter intelligence data through the use of semantic enhancement (SE). SE involves developing a suite of shared ontologies to semantically align heterogeneous data sources. This allows the various data resources to be searched and analyzed as a single resource. The key aspects discussed are developing the ontologies incrementally based on common principles, creating a shared semantic resource, and using annotation to semantically tag source data and link it to the ontologies. The goal is to facilitate horizontal integration of intelligence data across different organizations and systems in a flexible way.
