Natural language grammar to concept map

Hello
I am interested to know if techniques exist for the transformation of English grammar diagrams, such as Phrase Bracketing converted to concept maps. I understand concept mapping but I can't find a source that explains diagramming conventions used by linguists to be able to relate the two approaches.
thanks

Ontology domain v universe and reusing existing ontologies

So far, this book and discussion appear to be exactly what I need to evaluate creating an ontology; I look forward to the next few weeks. My initial comment is that the quoted definitions for Artificial Intelligence and Knowledge Representation include the header term in the definition. (Foundations section)
Here are some initial questions. If topics will be covered later, I can re-post after doing the reading.

1. How would you distinguish a universe from a domain when discussing an ontology?
2. Does the Evaluating Ontologies section in Chapter 2 discuss incorporating portions of existing ontologies into a new ontology? If not, that's my primary question.

I'm unable to attend week 1 discussion, but will listen to the recording and review any chat/feedback. Thank you.

Patterns

I have a particular interest in spatial relation patterns found in natural language that I want to model as ontology patterns. I have not received the book yet and hope there is some discussion about patterns as they bridge NL and ontology. Perhaps we can discuss the role or function of patterns during book club sessions. Thanks, Dalia

Ch 2 Section 2.5 Evaluating Ontologies: Correctness

How can ontologies be evaluated for correctness of content, and not just for logical consistency and coherence? Is this all done during authoring or are there approaches for doing it retrospectively?

Regression testing

Chapter 4, pg 48, #8 under steps involved in ontology development.
Could you please give an example of what is meant with regression testing as the ontology evolves?

CH 2.1 Domain Analysis: Modeling Choices based on Implementation

Does the implementation architecture of an application or knowledge graph affect the ontology design, or should OWL ontologies be implementation agnostic beyond profiles? For example, should subclass relationships ever be explicitly defined instead of inferred due to a constraint of not having access to a reasoner, and how would these constraints be integrated into the ontology engineering process?

Chapter 2 - From Data Model to Concept Model?

Question to Chapter 2.4 BUSINESS VOCABULARY DEVELOPMENT

In an enterprise a knowledge graph project often uses relational data from existing applications.
So, there is already a detailed data model available with the schema.

What is the best way to transfer that data model into a concept model representing real things, propeties and logic?

Thanks,
Marcus

Description Logics and complexity theory

Ontologies are based in fragments of first-order logic that are decidable. Given that they are decidable, an algorithm will halt (eventually) on an input that follows that DL. Most ontology editors have the ability to execute a reasoner that eventually halts, but are there good estimates on the time complexity it takes for those reasoners to run? Are there any resources that you can recommend related to the time complexities of reasoning over ontologies and the trade-offs between different reasoner implementations?
