# Project arXiv Citation Network
## 0. Usage
### Data Preparation
To prepare the data, run the following command:
```bash
python3 cite_parser.py
```
This will generate csv files for the nodes and edges of the citation network.
### Neo4j Database
To load the data into a Neo4j database, run the following command:
```bash
python3 load_neo4j.py
```
This will load the data from the csv files into a Neo4j database.
> [!NOTE]
> If it takes too long to load the data, you can change the number of random samples in the `prepare_data.py` file (`N_SAMPLES` variable).
## 1. Introduction
This project aims to analyze the citation network of arXiv papers. We use Python to clean the data and create a Neo4j network to visualize and analyze the citation relationships between arXiv papers.
## 2. Data Description
The data was extracted from: [https://github.com/mattbierbaum/arxiv-public-datasets/releases/tag/v0.2.0](https://github.com/mattbierbaum/arxiv-public-datasets/releases/tag/v0.2.0). More exactly, we'll use the file `internal-references-v0.2.0-2019-03-01.json.gz`, which contains the list of papers and their references, all papers using their arXiv IDs and `oai-arxiv-metadata-hash-abstracts-2019-03-01.json`, which contains the metadata of the papers.
The processed dataset is stored in JSON format. It contains metadata for arXiv papers, including titles, authors, abstracts, and references. The data is stored in two files:
- `data/oai-arxiv-metadata-hash-abstracts-2019-03-01.json`
- `data/internal-references-pdftotext.json`
### Neo4j Network
Using Neo4j, we created a citation network for the arXiv papers. The nodes represent papers and categories, while the edges represent citation and categorization relationships. By running the Neo4j command:
```cypher
MATCH (n) RETURN n
```
we visualize the citation network where:
- **Paper nodes** have attributes such as:
- `elementId`: Element ID of the paper
- `id`: Identifier of the paper
- `abstract_md5`: MD5 hash of the abstract
- `authors`: List of authors
- `doi`: Digital Object Identifier
- `idAxv`: arXiv identifier
- `report_no`: Report number
- `submitter`: Paper submitter
- `title`: Paper title
- **Category nodes** have attributes like:
- `elementId`: Element ID of the category
- `id`: Identifier of the category in the graph
- `category`: Name of the category
- **Relationships**:
- **CATEGORIZED**: Connects papers to categories. It has attributes `elementId` and `id`.
- **CITES**: Represents citations between papers. It has attributes `elementId` and `id`.
The network consists of **313 nodes** and **667 relationships**.
## 3. Analysis
### 3.1 Network Metrics
#### Average Citations per Paper
- The average number of citations per paper is **0.783**.
- This suggests that many papers are either not cited frequently or not cited at all.

Maximums:
- The table reveals that the most popular category is _hep-ph_ (High Energy Physics - Phenomenology) with 95 papers, followed by _hep-th_ (High Energy Physics - Theory) with 80 papers. The least popular categories are _math.GN_ (General Topology) and _cs.DM_ (Discrete Mathematics), each with only 1 paper.
- The most frequently cited paper is titled "Stringy Instantons at Orbifold Singularities," which has been cited 3 times.
- The maximum number of papers authored by a single author is 2, with 14 different authors contributing exactly 2 papers each.
Density:
- The network's density is calculated as 217 (the total number of `CITES` links) divided by 38,226 (the total number of possible `PAPER` node pairs), yielding a density of 0.005. This indicates that the network is very sparse, which is typical of citation networks. Not all papers cite every other paper, and citations are generally selective.
### 3.2 Node pair metrics
- The most cocitation:
- We picked the top 4 cocitation pairs to show the most cocitation pairs since the table is too long to show all of them.
| Paper1 | Paper2 | CoCitationCount |
| -------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- | --------------- |
| "Strong Phase and $D^0-D^0bar$ mixing at BES-III" | "D-\bar D mixing and rare D decays in the Littlest Higgs model with non-unitarity matrix" | 2 |
| "Marginal Solutions for the Superstring" | "Analytic solutions for marginal deformations in open superstring field theory" | 2 |
| "Numerical Evaluation of Six-Photon Amplitudes" | "Direct extraction of one-loop integral coefficients" | 2 |
| "Improved Measurement of the Positive Muon Lifetime and Determination of the Fermi Constant" | "Measurement of the Rate of Muon Capture in Hydrogen Gas and Determination of the Proton's Pseudoscalar Coupling $g_P$" | 2 |
- The table is make sense since the most cocitation pairs are the pairs that are related to each other. For example, the first pair is about the mixing of D mesons and the second pair is about the marginal solutions for the superstring.
- The most bibliographic coupling:
| Paper1 | Paper2 | BibliographicCouplingCount |
| --------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------ | -------------------------- |
| "Implication of the D^0 Width Difference On CP-Violation i n D^0-\bar D^0 Mixing" | "D0-anti-D0 Mixing and CP Violation in D0 vs anti-D0 to K\* (+-) K(-+) Decays" | 2 |
| "Marginal deformations in string field theory" | "Real analytic solutions for marginal deformations in open superstring field theory" | 2 |
| "On-Shell Methods in Perturbative QCD" | "One-loop phi-MHV amplitudes using the unitarity bootstrap" | 2 |
| "Muon Physics: A Pillar of the Standard Model" | "Electroweak Radiative Corrections to Muon Capture" | 2 |
- From the cocitation and bibliographic coupling tables, we can see that the most cocitation and bibliographic coupling pairs are related to each other. On the one hand, the number of cocitation and bibliographic coupling pairs is very low compared to the number of papers. This is because not all papers are cited by all other papers and vice versa which is common in citation networks.
### 3.3 Nodes Metrics
1. **The paper with the highest degree (using Neuler):**
The result shows that the paper titled _"Moriond QCD 2007 - Theory Summary"_ has the most connections to other papers, with 5 citations.
2. **The paper with the highest betweenness centrality (using Neuler):**
The result shows that the paper titled _"Moriond QCD 2007 - Theory Summary"_ has the highest betweenness centrality with a score of 24. This indicates that this paper plays the most crucial role in the network, acting as a bridge on the shortest paths between other papers.
3. **The paper with the highest closeness centrality (using Neuler):**
The result shows that all papers have the same closeness centrality score of 1. This suggests that each paper is equally close to all other papers in the network, meaning they either cite or are cited by each other. This is typical in citation networks where papers are interconnected.
4. **The paper with the highest eigenvector centrality (using Neuler):**
The result shows that the following papers have the highest eigenvector centrality with a score of 0.45:
- _"Marginal Solutions for the Superstring"_
- _"Analytic Solutions for Marginal Deformations in Open Superstring Field Theory"_
- _"Direct Extraction of One-Loop Integral Coefficients"_
- _"Numerical Evaluation of Six-Photon Amplitudes"_
This means that these papers are the most influential and prestigious in the network since they are cited by other important papers.
5. **Papers with the highest clustering coefficient (using Neuler):**
The results show that there are 30 papers with the highest clustering coefficient of 1. This indicates that these papers form a highly interconnected cluster where they cite each other, which is common in citation networks, especially among papers in the same category.
## 4. Limitation
- This analysis is that the Neo4j graph is not large enough to fully represent all 4,000 papers, which means the results may not be entirely accurate.
- The analysis is based solely on the data present in the graph database, which may not provide a comprehensive view of the citation network.
- The data is limited to arXiv papers, which may not represent the entire field of research in the scientific community.
- The dataset is released in April 2019, which may not include the most recent papers and citations.
- We just generate a subset of the data to analyze the network due to the limitation of the computer's memory and processing power. This may lead to inaccurate results.
## 5. Conclusion
Through the application of various data analysis techniques and tools, we effectively analyzed the citation network to identify key papers, popular categories, frequently co-cited and bibliographically coupled pairs, and influential publications. This analysis offers insights into the citation network's structure and the relationships among its papers.
However, the analysis is limited by the incomplete dataset within the graph database, which restricts a comprehensive representation of the network. Future work will prioritize refining the data collection algorithms to capture a more complete and accurate view of the citation network.
