<!-- # 👋🏻 Introduction

ResearchArcade is a graph interface for academic tasks. It utilizes a coherent multi-table format with graph structures to organize data from different sources and multiple modalities. And it preserves temporal evolution at both the manuscript and community levels. -->

# 🧭 Motivation

Academic data is distributed across multiple platforms (e.g., ArXiv, OpenReview) and modalities (text, figures, tables, reviews). ResearchArcade unifies these heterogeneous data sources into a single graph-based interface to enable large-scale, structured, and temporal analysis of academic dataset.

### Core Features

- **Multi-Source**: ArXiv (Academic Corpora) & OpenReview (Peer Reviews and Manuscript Revisions)
- **Multi-Modal**: Figures and Tables in Academic Corpora
- **Highly Structural and Heterogeneous**: Data can be intuitively viewed as heterogeneous graphs with multi-table format
- **Dynamically Evolving**: Manuscript (Intra-paper) Level (e.g., Paper Revision) & Community (Inter-paper) Level (e.g., Paper Citation with Timestamp)
- **Highly Scalable**: Graph is readily extensible as new items can be added by simply appending a row to the table

### Data Illustration

![data_description](https://raw.githubusercontent.com/ulab-uiuc/research-arcade/main/assets/research_arcade.png)

Tables are classified into **node tables** (colored) or **edge tables** (black and white). The blue (denoting the OpenReview part) or red (denoting the ArXiv part) columns represent the unique identification of each node or edge, and the remaining columns represent the features of the nodes or edges. The conversion from the multiple tables to heterogeneous graphs is straightforward.

# 🚀 Get started

### Supported Features

- **Dual Backend Support**: CSV backend & PostgreSQL backend
- **Comprehensive Data**
    - **OpenReview**: Support for papers, authors, reviews, revisions, paragraphs, and their interconnections
    - **ArXiv**: Support for papers, authors, paragraphs, sections, figures, tables and their interconnections
- **Flexible Data Import**: Load data from OpenReview API, Arxiv API, CSV files, or JSON files
- **Flexible Data Output**: The output data is in the format of `pd.Dataframe`, and they can be conveniently converted into CSV or JSON files.
- **Graph-like Operations**: Navigate relationships between entities
    - **OpenReview**: authorship (paper-author), comment-under-paper (paper-review), revision-of-paper (paper-revision), revision-caused-by-review (revision-review), etc.
    - **ArXiv**: citationship (paper-paper), authorship (paper-author), paragraph-of-paper (paper-paragraph), figure-of-paper (paper-figure), table-of-paper (paper-table), etc.
- **CRUD Operations**: Full support for Create, Read, Update, and Delete operations on all entities
- **Continuous Crawling**: Automatically crawls newly updated arXiv data and integrates it into the graph

### Setup
#### 1. Environment Setup
- Python ≥ 3.9 (tested on 3.10)
- PostgreSQL ≥ 14 (for SQL backend)
- Conda ≥ 22.0 (recommended)
- API keys:
  - Semantic Scholar API

##### Python Setup
```bash
# create a new environment
conda create -n research_arcade python=3.10
conda activate research_arcade

# install research_arcade through pip
pip install research_arcade
```

##### PostgreSQL Setup (Optional)
```bash
# Download Source File
wget https://ftp.postgresql.org/pub/source/v16.2/postgresql-16.2.tar.gz
tar -xvzf postgresql-16.2.tar.gz
cd postgresql-16.2

# Set Installation Path
export INSTALL_DIR=/YOUR/INSTALL/DICT
mkdir -p $INSTALL_DIR

# Compile and Install
./configure --prefix=$INSTALL_DIR --without-icu --without-readline
make
make install

# Add PostgreSQL to PATH
export PATH=$INSTALL_DIR/bin:$PATH

# Set the Data Directory
export PGDATA=/YOUR/DATA/DICT
mkdir -p $PGDATA

# Initialize Database
### WARNING: Initialize Again will Clean the Database ####
initdb -D $PGDATA

# Launch Database
pg_ctl -D $PGDATA -l logfile start

# Create Database
createdb iclr_openreview_database
psql iclr_openreview_database

# Configure PostgreSQL to Python Access (Enable TCP Listening)
nano $PGDATA/postgresql.conf
### add at the end of the file ###
listen_addresses = 'localhost'
port = 5432
### add at the end of the file ###

# Allow TCP Connection Authentication
nano $PGDATA/pg_hba.conf
### add at the end of the file ###
# Allow local TCP connections to use md5 password authentication
host    all             all             127.0.0.1/32            md5
### add at the end of the file ###

# Restart Database when it Lost Connection
pg_ctl -D $PGDATA restart
```

#### 2. Configure Environment Variables

To run the code, you’ll need to set up environment variables such as your **Semantic Scholar API key** and **Database Configurations**.

Copy the template file into the project root directory:
```bash
cp .env.template .env
```

#### 3. Backend Selection

##### Initialize with CSV Backend

```python
from research_arcade import ResearchArcade

research_arcade = ResearchArcade(
    db_type="csv",
    config={"csv_dir": "/path/to/csv/data/"}
)
```

##### Initialize with SQL Backend

```python
from research_arcade import ResearchArcade

research_arcade = ResearchArcade(
    db_type="sql",
    config={
        "host": "localhost",
        "dbname": "conference_db",
        "user": "username",
        "password": "password",
        "port": "5432"
    }
)
```

### Core Operations

The following examples demonstrate the core operations available in ResearchArcade. For comprehensive examples covering all supported tables and operations, please refer to the `examples/tutorials.ipynb` file in the repository.

#### Table Construction

```python
# From API
config = {"venue": "ICLR.cc/2025/Conference"}
research_arcade.construct_table_from_api("openreview_papers", config)

# From CSV file
config = {"csv_file": "/path/to/papers.csv"}
research_arcade.construct_table_from_csv("openreview_papers", config)

# From JSON file
config = {"json_file": "/path/to/papers.json"}
research_arcade.construct_table_from_json("openreview_papers", config)
```

#### Query Operations

```python
# Get all entities
papers_df = research_arcade.get_all_node_features("openreview_papers")

# Get specific entity by ID
paper_id = {"paper_openreview_id": "zGej22CBnS"}
paper = research_arcade.get_node_features_by_id("openreview_papers", paper_id)

# Get relationships
paper_authors = research_arcade.get_neighborhood("openreview_papers_authors", paper_id)
```

#### Node Manipulation

```python
# Insert new node
new_author = {
    'venue': 'ICLR.cc/2025/Conference',
    'author_openreview_id': '~john_doe1',
    'author_full_name': 'John Doe',
    'email': 'john@university.edu',
    'affiliation': 'University Name'
}
research_arcade.insert_node("openreview_authors", node_features=new_author)

# Update existing node
updated_paper = {
    'paper_openreview_id': 'paper123',
    'title': 'Updated Title',
    # ... other fields
}
research_arcade.update_node("openreview_papers", node_features=updated_paper)

# Delete a node
review_id = {"review_openreview_id": "review456"}
research_arcade.delete_node_by_id("openreview_reviews", review_id)
```

#### Edge Manipulation

```python
# Create an edge
paper_author_edge = {
    'venue': 'ICLR.cc/2025/Conference',
    'paper_openreview_id': 'paper123',
    'author_openreview_id': '~john_doe1'
}
research_arcade.insert_edge("openreview_papers_authors", paper_author_edge)

# Delete an edge
research_arcade.delete_edge_by_id("openreview_papers_authors", paper_author_edge)
```

#### Continuous Crawling

```python
research_arcade.continuous_crawling(interval_days=2, delay_days=2, paper_category='All', dest_dir="./download", arxiv_id_dest="./data")
```
