Andrea Gioia: Human-Centered Modeling for Data Products – Episode 30
Andrea Gioia
In recent years, data products have emerged as a solution to the enterprise problem of siloed data and knowledge.
Andrea Gioia helps his clients build composable, reusable data products so they can capitalize on the value in their data assets.
Built around collaboratively developed ontologies, these data products evolve into something that might also be called a knowledge product.
We talked about:
his work as CTO at Quantyca, a data and metadata management consultancy
his description of data products and their lifecycle
how the lack of reusability in most data products inspired his current approach to modular, composable data products - and brought him into the world of ontology
how focusing on specific data assets facilitates the creation of reusable data products
his take on the role of data as a valuable enterprise asset
how he accounts for technical metadata and conceptual metadata in his modeling work
his preference for a federated model in the development of enterprise ontologies
the evolution of his data architecture thinking from a central-governance model to a federated model
the importance of including the right variety business stakeholders in the design of the ontology for a knowledge product
his observation that semantic model is mostly about people, and working with them to come to agreements about how they each see their domain
Andrea's bio
Andrea Gioia is a Partner and CTO at Quantyca, a consulting company specializing in data management. He is also a co-founder of blindata.io, a SaaS platform focused on data governance and compliance. With over two decades of experience in the field, Andrea has led cross-functional teams in the successful execution of complex data projects across diverse market sectors, ranging from banking and utilities to retail and industry.

Dave McComb: Semantic Modeling for the Data-Centric Enterprise – Episode 29
Dave McComb
During the course of his 25-year consulting career, Dave McComb has discovered both a foundational problem in enterprise architectures and the solution to it.
The problem lies in application-focused software engineering that results in an inefficient explosion of redundant solutions that draw on overlapping data sources.
The solution that Dave has introduced is a data-centric architecture approach that treats data like the precious business asset that it is.
We talked about:
his work as the CEO of Semantic Arts, a prominent semantic technology and knowledge graph consultancy based in the US
the application-centric quagmire that most modern enterprises find themselves trapped in
data centricity, the antidote to application centricity
his early work in semantic modeling
how the discovery of the "core model" in an enterprise facilitates modeling and building data-centric enterprise systems
the importance of "baby step" approaches and working with actual customer data in enterprise data projects
how building to "enduring business themes" rather than to the needs of individual applications creates a more solid foundation for enterprise architectures
his current interest in developing a semantic model for the accounting field, drawing on his history in the field and on Semantic Arts' gist upper ontology
the importance of the concept of a "commitment" in an accounting model
how his approach to financial modeling permits near-real-time reporting
his Data-Centric Architecture Forum, a practitioner-focused event held each June in Ft. Collins, Colorado
Dave's bio
Dave McComb is the CEO of Semantic Arts. In 2000 he co-founded Semantic Arts with the aim of bringing semantic technology to Enterprises. From 2000- 2010 Semantic Arts focused on ways to improve enterprise architecture through ontology modeling and design. Around 2010 Semantic Arts began helping clients more directly with implementation, which led to the use of Knowledge Graphs in Enterprises. Semantic Arts has conducted over 100 successful projects with a number of well know firms including Morgan Stanley, Electronic Arts, Amgen, Standard & Poors, Schneider-Electric, MD Anderson, the International Monetary Fund, Procter & Gamble, Goldman Sachs as well as a number of government agencies. Dave is the author of Semantics in Business Systems (2003), which made the case for using Semantics to improve the design of information systems, Software Wasteland (2018) which points out how application-centric thinking has led to the deplorable state of enterprise systems and The Data-Centric Revolution (2019) which outlines a alternative to the application-centric quagmire.
Prior to founding Semantic Arts he was VP of Engineering for Velocity Healthcare, a dot com startup that pioneered the model driven approach to software development. He was granted three patents on the architecture developed at Velocity. Prior to that he was with a small consulting firm: First Principles Consulting. Prior to that he was part of the problem.

Andrea Volpini: The Role of Memory in Digital Branding for AI – Episode 27
Andrea Volpini
Your organization's brand is what people say about you after you've left the room. It's the memories you create that determine how people think about you later.
Andrea Volpini says that the same dynamic applies in marketing to AI systems. Modern brand managers, he argues, need to understand how both human and machine memory work and then use that knowledge to create digital memories that align with how AI systems understand the world.
We talked about:
his work as CEO at WordLift, a company that builds knowledge graphs to help companies automate SEO and other marketing activities
a recent experiment he did during a talk at an AI conference that illustrates the ability of applications like Grok and ChatGPT to build and share information in real time
the role of memory in marketing to current AI architectures
his discovery of how the agentic approach he was taking to automating marketing tasks was actually creating valuable context for AI systems
the mechanisms of memory in AI systems and an analogy to human short- and long-term memory
the similarities he sees in how the human neocortex forms memories and how the knowledge about memory is represented in AI systems
his practice of representing entities as both triples and vectors in his knowledge graph
how he leverages his understanding of the differences in AI models in his work
the different types of memory frameworks to account for in both the consumption and creation of AI systems: semantic, episodic, and procedural
his new way of thinking about marketing: as a memory-creation process
the shift in focus that he thinks marketers need to make, "creating good memories for AI in order to protect their brand values"
Andrea's bio
Andrea Volpini is the CEO of WordLift and co-founder of Insideout10. With 25 years of experience in semantic web technologies, SEO, and artificial intelligence, he specializes in marketing strategies. He is a regular speaker at international conferences, including SXSW, TNW Conference, BrightonSEO, The Knowledge Graph Conference, G50, Connected Data and AI Festival.
Andrea has contributed to industry publications, including the Web Almanac by HTTP Archive. In 2013, he co-founded RedLink GmbH, a commercial spin-off focused on semantic content enrichment, natural language processing, and information extraction.

Podcast intro transcript
This is the Knowledge Graph Insights podcast, episode number 27. Some experts describe the marketing concept of branding as, What people say about you after you’ve left the room. It's the memories they form of your company that define your brand. Andrea Volpini sees this same dynamic unfolding as companies turn their attention to AI. To build a memorable brand online, modern marketers need to understand how both human and machine memory work and then focus on creating memories that align with how AI systems understand the world.
