For background on this dataset, please check https://arxiv.org/abs/2405.20163.  

## 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.
