# Use Cases¶

## DRAFT: Work in progress¶

This material is a work in progress, at "rough draft" stage.

## Operationalizing AI¶

One of the major learnings from a decade-plus of data science is that AI adoption in enterprise requires more than one team. Instead there must be extensive cross-team coordination with executive support. Moreover, the projects cannot be merely proof-of-concept (POC) "one-offs". To sustain this kind of work, organizations must pursue more efficient, effective approaches often called Operationalizing AI to produce a steady stream of AI projects. One difficulty of course is that enterprise organization must often integrate with internal legacy systems.

The kglab library provides means for an enterprise organization to establish and explore a baseline implementation for a knowledge graph practice internally. If an organization can see where it needs to integrate with its legacy systems, or where features within kglab could be migrated into proprietary systems, then use of this library may dramatically reduce time-to-market key performance indicators for enterprise KG projects.

## Data Context¶

In a world where organizations must be resilient in the face of abrupt changes, we must adapt more resilient means for reconciling data from a wide variety of sources: vendors, customers, partners, government agencies, standards bodies, and so on.

KGs provide means for a kind of abstraction layer to make the data cohere.

However, it's not clear when Gartner will acknowledge the breadth of industry adoption for KG approaches in enterprise data management.

To paraphrase Natasha Noy, a research scientist at Google Research and highly-regarded practitioner in this field:

An "enterprise knowledge graph" provides ground truth through which we can reconcile our queries and other usage of many disparate data stores.

For example, having persistent identifiers with other metadata attached is a great start.

For several KG projects, we kept reusing a similar working set of libraries:

Each of these libraries provides a useful piece of the puzzle when you need to leverage knowledge representation, graph algorithms, entity linking, interactive visualization, metadata queries, axioms, etc. However, some of them are relatively low-level (e.g., rdflib) or perhaps not maintained as much (e.g., skosify) and there are challenges integrating them. Challenges we kept having to reinvent work-arounds to resolve.

There are general operations that one must perform on knowledge graphs:

• building triples
• managing a mix of namespaces
• serialization to/from multiple formats
• queries
• interactive visualization
• transitivity and other forms of enriching a graph
• graph algorithms
• inference (e.g., PSL, Bayesian Networks, Causal, MLN, etc.)
• quality assurance (e.g., axioms)
• parallel processing across a cluster
• embedding (deep learning integration)
• other ML integrations
