Government Funding Graph RAG
In this article, I present my latest open-source project — Government Funding Graph.
The inspiration for this project came from a desire to make better tooling for grant writing, namely to suggest research topics, funding bodies, research institutions, and researchers. I have made Innovate UK grant applications in the past, so I have had an interest in the government funding landscape for some time.
Concretely, a lot of the recent political discourse focuses on government spending, namely Elon Musk’s Department of Government Efficiency (DOGE) in the United States and similar sentiments echoed here in the UK, as Kier Starmer looks to integrate AI into government.
Perhaps the release of this project is quite timely. Albeit not the original intention, I hope as a secondary outcome of this article is that it inspires more exploration into open source datasets for public spending.

1. Definitions
What is UKRI?
UK Research and Innovation is a non-departmental public body sponsored by the Department for Science, Innovation and Technology (DSIT) that allocates funding for research and development. Generally, funding is awarded to research institutions and businesses.
“We invest £8 billion of taxpayers’ money each year into research and innovation and the people who make it happen. We work across a huge range of fields — from biodiversity conservation to quantum computing, and from space telescopes to innovative health care. We give everyone the opportunity to contribute and to benefit, bringing together people and organisations nationally and globally to create, develop and deploy new ideas and technologies.” — UKRI Website
What is a Graph?
A graph is a convenient data structure showing the relationships between different entities (nodes) and their relationships to each other (edges). In some instances, we also associate those relationships with a numerical value.
“In computer science, a graph is an abstract data type that is meant to implement the undirected graph and directed graph concepts from the field of graph theory within mathematics.
A graph data structure consists of a finite (and possibly mutable) set of vertices (also called nodes or points), together with a set of unordered pairs of these vertices for an undirected graph or a set of ordered pairs for a directed graph. These pairs are known as edges (also called links or lines), and for a directed graph are also known as edges but also sometimes arrows or arcs.” — Wikipedia

What is NetworkX?
NetworkX is a useful library in this project to construct and store our graph. Specifically, a digraph though the library supports many graph variants such as multigraphs, the library also supports graph-related utility functions.
“NetworkX is a Python package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.” — NetworkX Website
What is PyVis?
We use the PyVis Python package to create dynamic network views for our graph, screenshots of these can be found throughout the article.
“The pyvis library is meant for quick generation of visual network graphs with minimal python code. It is designed as a wrapper around the popular Javascript visJS library” — PyVis Docs
What is LlamaIndex?
LlamaIndex is a popular library for LLM applications, including support for agentic workflows, we use it to perform the graph RAG component of this project.
“LlamaIndex (GPT Index) is a data framework for your LLM application. Building with LlamaIndex typically involves working with LlamaIndex core and a chosen set of integrations (or plugins).” — LlamaIndex Github
What is Graph RAG?
Graph RAG at a high level (Image By Author)
Retrieval-augmented generation, or RAG as it is commonly known, is an AI framework for which additional context from an external knowledge base is used to ground LLM answers. Graph RAG, by extension, pertains to the use of a Graph to provide this additional context.
“GraphRAG is a powerful retrieval mechanism that improves GenAI applications by taking advantage of the rich context in graph data structures… Basic RAG systems rely solely on semantic search in vector databases to retrieve and rank sets of isolated text fragments. While this approach can surface some relevant information, it fails to capture the context connecting these pieces. For this reason, basic RAG systems are ill-equipped to answer complex, multi-hop questions. This is where GraphRAG comes in. It uses knowledge graphs to represent and connect information to capture not only more data points but also their relationships. Thus, graph-based retrievers can provide more accurate and relevant results by uncovering hidden connections that aren’t often obvious but are crucial for correlating information.” — Neo4j Website
What is Streamlit?
Streamlit is a lightweight Python web framework we will use to create the web application for this project.
“Streamlit is an open-source Python framework for data scientists and AI/ML engineers to deliver dynamic data apps with only a few lines of code. Build and deploy powerful data apps in minutes.” — Streamlit website
2. UKRI API
The UKRI API is a service that facilitates access to the public UKRI grant funding dataset, authentication is not required and the docs can be found here. I use only two endpoints for our application, they are the Search projects endpoint and the Projects endpoint. This allows a user to search for projects based on a keyword search and retrieve all project-specific information.
A search term, page size and page number are provided as query string parameters. The query string parameters;
selectedSortableField=pro.am&selectedSortOrder=DESC
Ensure that the results are returned by funded value descending.
I have also included the code I used for asynchronous pagination.
import math
import requests
import concurrent.futures
import os
from itertools import chain
import urllib.parse
import logging
def search_ukri_projects(args):
"""

"""
search_term, page_size, page_number = args
try:
encoded_search_term = urllib.parse.quote(search_term)
if (
(
response := requests.get(
f"https://gtr.ukri.org/api/search/project?term={encoded_search_term}&page={page_number}&fetchSize={page_size}&selectedSortableField=pro.am&selectedSortOrder=DESC&selectedFacets=&fields=project.abs",
timeout=10,
)
)
and (response.status_code == 200)
and (
items := response.json()
.get("facetedSearchResultBean", {})
.get("results")
)
):
return items
except Exception as error:
logging.exception("ERROR search_ukri_projects: %s", error)
return []
def search_ukri_paginate(search_term, number_of_results, page_size=100):
"""

"""
args = [
(search_term, page_size, page_number + 1)
for page_number in range(int(math.ceil(number_of_results / page_size)))
]
with concurrent.futures.ThreadPoolExecutor(os.cpu_count()) as executor:
future = executor.map(search_ukri_projects, args)
results = [result for result in future if result]
return list(chain.from_iterable(results))[:number_of_results]
The following function is used to get project-specific data using the unique UKRI project reference. The project reference is derived from the aforementioned project search results.
import requests
import logging
def get_ukri_project_data(project_grant_reference):
"""

try:
if (
(

and (items := response.json().get("projectOverview", {}))
):
return items
except Exception as error:
logging.exception("ERROR get_ukri_project_data: %s", error)
Similarly, we parse out the relevant data for the construction of the graph and remove superfluous information.
def parse_data(projects):
"""

data = []
for project in projects:
project_composition = project.get("projectComposition", {})

funder = fund.get("funder")
value_pounds = fund.get("valuePounds")
lead_research_organisation = project_composition.get("leadResearchOrganisation")
person_roles = project_composition.get("personRoles")
if all(
[
project_composition,
project_data,
fund,
funder,

]
):
record = {}

"resourceUrl", ""
)

record["project_url"] = project_data.get("resourceUrl")
data.append(record)
return data
3. Construct NetworkX Graph
There are different types of graphs, and I elected for a directed graph where the direction of the edges are important. More formally;
“A DiGraph stores nodes and edges with optional data, or attributes. DiGraphs hold directed edges. Self loops are allowed but multiple (parallel) edges are not.” — NetworkX Website
To construct the NetworkX graph, we must add nodes and edges — including the sequential updating of node attributes.
The standard attributes, compatible with PyVis graph rendering for nodes are as follows;
Title (The label that appears on hover over)
Group (The colour coding)
Size (How large the nodes appear in the graph)
We also use the custom attribute “funding”, which we will use to sum all of the funding for research and funding organizations. This will be normalized to set the node size according to the percentage of total funding for a particular group.
For our graph, we have nodes from four groups. They are classified as: funder_name, lead_research_organisation, project_title and person_name.
HTML links can be used in the node title to allow the user to easily click through to a URL. I have included a helper function to do this below. There are project, people, and research organisation-specific links that, if redirected to provide additional information to the user.
Government Funding Graph (Image By Author)
The code to construct the NetworkX graph can be seen below. The DiGraph class has methods to check if a graph already has a node and similarly for edges. There are also methods for adding nodes and edges. As we iterate through projects, we want to sum the total funding amount for the funding organization and lead research institution. There are methods to both get an attribute from a node in the graph and set an attribute on a node. Depending on the source and destination node, we also apply different titles and labels to reflect that specific predicate. These can be seen in the code below.

person_roles = row.get(

== role.get("name")
):
graph.add_edge(
person_name,
project_title,
title=role.get("name"),
label=role.get("name"),
)
return graph
Once the graph has been constructed and as previously described, I wanted to normalize the node sizes depending on the percentage of the total amount of funding for particular groups. I also append the total funding, both as a summation and as a percentage to the node label so it can be more easily viewed by a user.
The scale factor is just a multiple applied for aesthetic reasons, such that the node sizes appear relative to the other node groups present.

4. Filter a NetworkX Graph
Government Funding Graph UI (Image By Author)
I allow the user to filter nodes via the UI to create a subgraph. The form to do this in Streamlit is below. I also find the neighbors of neighbors for the filtered nodes. I had some issues with Pylint raising unnecessary comprehension errors from the generator, which I have disabled — more on Pylint later in the article. A smaller graph will take less time to render and will ensure that irrelevant context will be excluded.
import networkx as nx
import streamlit as st
def find_neighbor_nodes_helper(node_list, graph):
"""
Find unique node neighbors and flatten.
"""
successors_generator_array = [
# pylint: disable=unnecessary-comprehension
[item for item in graph.successors(node)]
for node in node_list
]
predecessors_generator_array = [
# pylint: disable=unnecessary-comprehension
[item for item in graph.predecessors(node)]
for node in node_list
]
neighbors = successors_generator_array + predecessors_generator_array
flat = sum(neighbors, [])
return list(set(flat))
def render_filter_form(annotated_node_data, graph):
"""
Render form to allow the user to define search nodes.
"""
st.session_state["filter"] = st.radio(
"Filter", ["No filter", "Filter results"], index=0, horizontal=True
)
if (filter_determinant := st.session_state.get("filter")) and (
filter_determinant == "Filter results"
):
st.session_state["node_group"] = st.selectbox(
"Entity type", list(annotated_node_data.keys())
)
if node_group := st.session_state.get("node_group"):
ordered_lookup = dict(
sorted(
annotated_node_data[node_group].items(),
key=lambda item: item[1].get("neighbor_len"),
reverse=True,
)
)
st.session_state["search_nodes_label"] = st.multiselect(
"Filter projects", list(ordered_lookup.keys())
)
if search_nodes_label := st.session_state.get("search_nodes_label"):
filter_nodes = [
ordered_lookup[label].get("label") for label in search_nodes_label
]
search_nodes_neighbors = find_neighbor_nodes_helper(filter_nodes, graph)
search_nodes = find_neighbor_nodes_helper(search_nodes_neighbors, graph)
st.session_state["search_nodes"] = list(
set(search_nodes + filter_nodes + search_nodes_neighbors)
)
NetworkX makes it easy to create a subgraph from a list of nodes with the subgraph_view function, which takes a callable as a parameter. The callable takes a graph node as a parameter and if the boolean True value is returned, the node would be included in the subgraph.
import networkx as nx
import streamlit as st
def filter_node(node):
"""
Check to see if the filter term is in the nodes selected.
"""
if (
(filter_term := st.session_state.get("filter"))
and (filter_term == "Filter results")
and (search_nodes := st.session_state.get("search_nodes"))
):
if node not in search_nodes:
return False
return True
graph = nx.subgraph_view(graph, filter_node=filter_node)
5. Graph Visualisation Using PyVis
To produce the visualizations I have presented earlier in the article, we must first convert the NetworkX graph to a PyVis network and then render the HTML file within the Streamlit UI.
If you are unfamiliar with Streamlit, you can see one of my other articles that explore the topic here.
Converting a NetworkX graph to PyVis format is relatively trivial and can be achieved with the code below. The Network class is the main class for visualization functionality, first we instantiate the class and in this example, the graph is directed. The barnes_hut method is then called, which is a gravity model. The from_nx method takes an existing NetworkX graph as an argument and translates it to PyVis, which is called in place.
from pyvis.network import Network
def convert_graph(graph):
"""
Convert networkx to pyvis graph.
"""
net = Network(
height="700px",
width="100%",
bgcolor="#222222",
font_color="white",
directed=True,
)
net.barnes_hut()
net.from_nx(graph)
return net
To render the Graph to the UI, we first create a unique user ID as we use the PyVis save_graph method to save the HTML file for the graph on the server. The uuid ensures a unique file name, which is then read into the streamlit UI and after the file is deleted.
import uuid
import contextlib
import os
import streamlit as st
def render_graphs(net):
"""
Helper to render graph visualization from pyvis graph.
"""
uuid4 = uuid.uuid4()
file_name = f"./output/{uuid4}.html"
with contextlib.suppress(FileNotFoundError):
os.remove(file_name)
net.save_graph(file_name)
with open(file_name, "r", encoding="utf-8") as html_file:
source_code = html_file.read()
st.components.v1.html(source_code, height=650, width=650)
os.remove(file_name)
6. Graph RAG Using LlamaIndex
Government Funding Graph RAG (Image By Author)
Through graph retrieval-augmented generation, we can query our graph data directly, an example can be seen in the prior screenshot. Extracted entities from the user query are looked up in the graph to give specific context to the AI to ground its response, as this information would likely not have been in the training corpus, and hence any answer given would have had an increased likelihood of being a hallucination.
We create a chat engine to pass a user’s previous query history into the model. Usually, the Open AI API key is read as an environment variable within LlamaIndex — however, since this is user-submitted for our application and we don’t want to save users’ Open AI credentials, we need to pass credentials to the LLM and embedding model classes as keyword arguments.
We then create an empty LlamaIndex Knowledge Graph Index and populate the knowledge graph by inserting triples. The triples come from traversing the edges of our NetworkX graph and calling the upsert_triplet_and_node method, which will create the triple and node if they don’t already exist.
Since the graph is directed, we can interchange the subjects and objects so that the graph is traversable in either direction. The chat engine uses the tree_summarize option for the response builder.
“Tree summarize response builder. This response builder recursively merges text chunks and summarizes them in a bottom-up fashion (i.e. building a tree from leaves to root). More concretely, at each recursively step: 1. we repack the text chunks so that each chunk fills the context window of the LLM 2. if there is only one chunk, we give the final response 3. otherwise, we summarize each chunk and recursively summarize the summaries.”— LlamaIndex Website
Calling the chat method with the user’s query and constructing the chat history from the Streamlit state object is included here.

7. Linting With Pylint
Government Funding Graph (Image By Author)
Since I have left some comments in the code to disable the linter in the examples above (examples are referenced from the GitHub repo), I thought I’d cover the topic of linting briefly.
For those unfamiliar, linting helps to check your code for potential bugs and stylistic issues. Linters automatically enforce coding standards.
To get started, install Pylint by running the command.
pip install pylint
Secondly, we need to create a .pylintrc file at the root of the project (we can also set default global and user-specific settings depending on where we create the .pylintrc file). To do this, you will need to run.
pylint --generate-rcfile > .pylintrc
We can configure this file to fit our preferences by updating the default values within the .pylintrc file.
To run the linter manually, you can use.
pylint ./main.py && pylint ./**/*.py
When the Docker image is built, it will automatically run Pylint and raise an error should it detect an issue with the code. This can be seen in the Dockerfile.
FROM python:3.10.16 AS base
WORKDIR /app
COPY requirements.txt .
RUN pip install --upgrade pip
RUN pip install -r requirements.txt
COPY . .
RUN mkdir -p /app/output
RUN pylint ./main.py && pylint ./**/*.py
RUN python -m unittest -v tests.test_ukri_utils.Testing
CMD ["streamlit", "run", "./main.py"]
A popular formatter that you might also find useful is Black —
“Black is a PEP 8 compliant opinionated formatter. Black reformats entire files in place.”
Running Black will automatically resolve some of the issues that would be raised by the linter.
