| pretty_name: Using KGs to test knowledge consistency in LLMs |

|
| ## What it is: |
| Each dataset in this delivery is made up of query clusters that test an aspect of the consistency of the LLM knowledge about a particular domain. All the questions in each |
| cluster are meant to be answered either 'yes' or 'no'. When the answers vary within a cluster, the knowledge is said to be inconsistent. When all the questions in a cluster |
| are answered 'no' when the expected answer is 'yes' (or viceversa), the knowledge is said to be 'incomplete' (i.e., maybe the LLM wasn't trained in that particular domain). |
| It is our experience that incomplete clusters are very few (less than 3%) meaning that the LLMs we have tested know about the domains included here (see below for a list of the |
| individual datasets), as opposed to inconsistent clusters, which can be between 6%-20% of the total clusters. |
|
|
| ## How it is made: |
| The questions and clusters are automatically generated from a knowledge graph from seed concepts and properties. In our case, we have used Wikidata, |
| a well known knowledge graph. The result is an RDF/OWL subgraph that can be queried and reasoned over using Semantic Web technology. |
|
|
| ## Types of query clusters |
|
|
| There are different types of query clusters depending on what aspect of the knowledge graph and its deductive closure they capture: |
|
|
| Edge clusters test a single edge using different questions. For example, to test the edge ('orthopedic pediatric surgeon', IsA, 'orthopedic surgeon), the positive |
| or 'edge_yes' (expected answer is 'yes') cluster is: |
| |
| "is 'orthopedic pediatric surgeon' a subconcept of 'orthopedic surgeon' ?", |
| "is 'orthopedic pediatric surgeon' a type of 'orthopedic surgeon' ?", |
| "is every kind of 'orthopedic pediatric surgeon' also a kind of 'orthopedic surgeon' ?", |
| "is 'orthopedic pediatric surgeon' a subcategory of 'orthopedic surgeon' ?" |
| |
| There are also inverse edge clusters (with questions like "is 'orthopedic surgeon' a subconcept of 'orthopedic pediatric surgeon' ?") and negative or 'edge_no' clusters |
| (with questions like "is 'orthopedic pediatric surgeon' a subconcept of 'dermatologist' ?") |
|
|
| Hierarchy clusters measure the consistency of a given path, including n-hop virtual edges (in graph's the deductive closure). For example, the path |
| ('orthopedic surgeon', 'surgeon', 'medical specialist', 'medical occupation') is tested by the cluster below |
|
|
| "is 'orthopedic surgeon' a subconcept of 'surgeon' ?", |
| "is 'orthopedic surgeon' a type of 'surgeon' ?", |
| "is every kind of 'orthopedic surgeon' also a kind of 'surgeon' ?", |
| "is 'orthopedic surgeon' a subcategory of 'surgeon' ?", |
| "is 'orthopedic surgeon' a subconcept of 'medical specialist' ?", |
| "is 'orthopedic surgeon' a type of 'medical specialist' ?", |
| "is every kind of 'orthopedic surgeon' also a kind of 'medical specialist' ?", |
| "is 'orthopedic surgeon' a subcategory of 'medical specialist' ?", |
| "is 'orthopedic surgeon' a subconcept of 'medical_occupation' ?", |
| "is 'orthopedic surgeon' a type of 'medical_occupation' ?", |
| "is every kind of 'orthopedic surgeon' also a kind of 'medical_occupation' ?", |
| "is 'orthopedic surgeon' a subcategory of 'medical_occupation' ?" |
| |
| Property inheritance clusters test the most basic property of conceptualization. If an orthopedic surgeon is a type of surgeon, we expect that |
| all the properties of surgeons, e.g., having to be board certified, having attended medical school or working on the field of surgery, are inherited by orthopedic surgeons. |
| The example below tests the later: |
|
|
| "is 'orthopedic surgeon' a subconcept of 'surgeon' ?", |
| "is 'orthopedic surgeon' a type of 'surgeon' ?", |
| "is every kind of 'orthopedic surgeon' also a kind of 'surgeon' ?", |
| "is 'orthopedic surgeon' a subcategory of 'surgeon' ?", |
| "is the following statement true? 'orthopedic surgeon works on the field of surgery' ", |
| "is the following statement true? 'surgeon works on the field of surgery' ", |
| "is it accurate to say that 'orthopedic surgeon works on the field of surgery'? ", |
| "is it accurate to say that 'surgeon works on the field of surgery'? " |
| |
|

|
| ## List of datasets |
|
|
| To show the versatility of our approach, we have constructed similar datasets in the domains below. We test one property inheritance per dataset. The Wikidata main QNode |
| (the node corresponding to the entities) and PNode (the node corresponding to the property) are indicated in parenthesis. |
