Horizontal Integration of Intelligence
Horizontal Integration• “Horizontally integrating warfighter intelligence data
… requires access (including discovery, search, retrieval, and display) to intelligence data among the warfighters and other producers and consumers via standardized services and architectures. These consumers include, but are not limited to, the combatant commands, Services, Defense agencies, and the Intelligence Community.”

Challenges to the horizontal integration of Intelligence Data
• Quantity and variety– Need to do justice to radical heterogeneity in the
representation of data and semantics Dynamic environments
– Need agile support for retrieval, integration and enrichment of data
• Emergence of new data resources– Need in agile, flexible, and incremental integration
approach
Horizontal integration
=def. multiple heterogeneous data resources become aligned in such a way that search and analysis procedures can be applied to their combined content as if they formed a single resource
6This
7will not yield horizontal integration
Strategy• Strategy to avoid stovepipes requires a solution that is
– Stable – Incrementally growing– Flexible in addressing new needs– Independent of source data syntax and semantics
The answer: Semantic Enhancement (SE), a strategy of external (arm’s length) alignment

Dataspace on the Cloud• Cloud (Bigtable-like) store of heterogeneous data and
data semantics– Unified representation of structured and unstructured data– Without loss and or distortion of data or data semantics
• Homogeneous standardized presentation of heterogeneous content via a suite of SE ontologies

Basis of the SE Approach
SE ontology labels
• Focusing on the terms (labels, acronyms, codes) used in the source data.
• Where multiple distinct terms {t1, …, tn} are used in separate data sources with one and the same meaning, they are associated with a single preferred label drawn from a standard set of such labels
• All the separate data items associated with the {t1, … tn} thereby linked together through the corresponding preferred labels.
• Preferred labels form basis for the ontologies we build

SE Requirements to achieve Horizontal Integration
• The ontologies must be linked together through logical definitions to form a single, non-redundant and consistently evolving integrated network
• The ontologies must be capable of evolving in an agile fashion in response to new sorts of data and new analytical and warfighter needs our focus here
Creating the SE Suite of Ontology Modules• Incremental distributed ontology development
– based on Doctrine; – involves SMEs in label selection and definition
• Ontology development rules and principles– A shared governance and change management process– A common ontology architecture incorporating a common,
domain-neutral, upper-level ontology (BFO)• An ontology registry • A simple, repeatable process for ontology development• A process of intelligence data capture through ‘annotation’
or ‘tagging’ of source data artifacts• Feedback between ontology authors and users

Ontology Development Principles• Reference ontologies – capture generic content
and are designed for aggressive reuse in multiple different types of context– Single inheritance– Single reference ontology for each domain of
interest• Application ontologies – created by combining
local content with generic content taken from relevant reference ontologies
Illustration
vehicle =def: an object used for transporting people or goods
tractor =def: a vehicle that is used for towing
crane =def: a vehicle that is used for lifting and moving heavy objects
vehicle platform=def: means of providing mobility to a vehicle
wheeled platform=def: a vehicle platform that provides mobility through the use of wheels
tracked platform=def: a vehicle platform that provides mobility through the use of continuous tracks
artillery vehicle = def. vehicle designed for the transport of one or more artillery weapons
wheeled tractor = def. a tractor that has a wheeled platform
Russian wheeled tractor type T33 = def. a wheeled tractor of type T33 manufactured in Russia
Ukrainian wheeled tractor type T33 = def. a wheeled tractor of type T33 manufactured in Ukraine

Black – reference ontologies
Red – application ontologies
Role of Reference Ontologies• Normalized (compare Ontoclean)
– Allows us to maintain a set of consistent ontologies – Eliminates redundancy
• Modular– A set of plug-and-play ontology modules– Enables distributed development
• Surveyable– Common principles used, common training and
governance
Examples of Principles• All terms in all ontologies should be singular nouns• Same relations between terms should be reused in
every ontology• Reference ontologies should be based on single
inheritance• All definitions should be of the form
an S = Def. a G which Dswhere ‘G’ (for: species) is the parent term of S in the corresponding reference ontology
SE Architecture• The Upper Level Ontology (ULO) in the SE hierarchy
must be maximally general (no overlap with domain ontologies)
• The Mid-Level Ontologies (MLOs) introduce successively less general and more detailed representations of types which arise in successively narrower domains until we reach the Lowest Level Ontologies (LLOs).
• The LLOs are maximally specific representation of the entities in a particular one-dimensional domain

Shared Semantic Resource
• Growing collection of shared ontologies asserted and application
• Pilot program to coordinate a small number of development communities including both DSC (internal) and external groups to produce their ontologies according to the best practice guidelines of the SE methodology
• Given the principles of building the SE (governance, distributed incremental development, common architecture) the next step is to create a semantic resource that can be shared by a larger community, and used for inter- and intra-integration on numerous systems
