paperscout 0.1.0

A multi-purpose tool for searching, downloading, and managing academic papers

paperscout

A multi-purpose tool for searching, downloading, and managing academic papers.

Features

• Search papers across multiple sources using pluggable backends
• Download papers by DOI or arXiv ID
• Programmatic API and CLI interface
• Backend architecture for easy addition of new sources
• Smart title matching - searches across title and abstract

Installation

pip install paperscout

With all backend support

pip install paperscout[arxiv]
# or install all optional dependencies
pip install paperscout[all]

Available backend extras:

• arxiv - arXiv backend using arxivy
• dblp - DBLP backend using dblpcli
• s2cli - Semantic Scholar backend using s2cli
• acl-anthology - ACL Anthology backend

Backend Architecture

The package uses a backend architecture where each source has its own backend implementation:

paperscout/
├── backends/
│   ├── base.py              # Base backend class (abstract)
│   ├── arxiv.py             # arXiv backend using arxivy
│   ├── dblp.py              # DBLP backend using dblpcli
│   ├── s2cli.py             # Semantic Scholar backend using s2cli
│   └── acl_anthology.py     # ACL Anthology backend
├── similarity.py            # Title similarity functions
├── search.py                # Searcher using backends
├── client.py                # Client using searchers
└── formatter.py             # Rich formatting for CLI output

To add a new backend:

1. Create a new module in backends/ (e.g., pubmed.py)
2. Implement the BaseBackend abstract class
3. Register it in PaperSearcher.BACKENDS

CLI Usage

Commands

Command	Description
search	Search for papers across sources
match	Get the best matching paper by title
download	Download a paper

Search Papers

# Search all backends (default - ACL Anthology has priority)
paperscout search "Attention Is All You Need"

# Search specific source
paperscout search "Transformer" --source arxiv
paperscout search "Attention" --source acl_anthology

# Limit results
paperscout search "quantum computing" --limit 20

# Output as JSON
paperscout search "query" --json

# Save to file
paperscout search "query" --output results.txt

Get Best Match

# Get the single best matching paper
paperscout match "Attention Is All You Need"

# Specify source
paperscout match "Transformer" --source arxiv

# JSON output
paperscout match "query" --json

Download Paper

# Download by arXiv ID
paperscout download arXiv:2301.12345

# Download by DOI
paperscout download 10.1234/example.doi

# Specify output directory
paperscout download arXiv:2301.12345 --output ./papers

# JSON output
paperscout download arXiv:2301.12345 --json

Python API

Using the Client

from paperscout import PaperFinderClient

# Create client
client = PaperFinderClient()

# Search for papers (ACL Anthology has priority)
results = client.search("Attention Is All You Need", source="all", limit=10)
for paper in results:
    print(f"{paper['title']} - {paper['authors']}")

# Search specific source only
results = client.search("Transformer", source="arxiv", limit=5)

# Download a paper
client.download("arXiv:2301.12345", output_dir="./papers")

Using Backends Directly

from paperscout.backends.acl_anthology import ACLAnthologyBackend
from paperscout.backends.arxiv import ArxivBackend
from paperscout.backends.dblp import DblpBackend
from paperscout.backends.s2cli import SemanticScholarBackend

# Use ACL Anthology backend
backend = ACLAnthologyBackend()
results = backend.search("Attention Is All You Need", limit=10)

# Use arXiv backend
arxiv_backend = ArxivBackend()
papers = arxiv_backend.search("quantum computing", limit=5)

# Download from any backend
backend.download("arXiv:2301.12345")

Searching by Similarity

from paperscout.search import PaperSearcher
from paperscout.similarity import _title_similarity

searcher = PaperSearcher()

# Search all backends with exact match priority
results = searcher.search("Transformer", exact_match_first=True)

# Calculate title similarity
similarity = _title_similarity(
    "Attention Is All You Need",
    "Attention Is All You Need"
)
print(similarity)  # 1.0 for exact match

Sources

Source	Backend	Description
all	Multiple	Searches all backends (ACL Anthology has priority)
arxiv	ArxivBackend	Preprints in physics, math, CS, and more
dblp	DblpBackend	Computer science bibliography
semantic_scholar	SemanticScholarBackend	Academic paper search
acl_anthology	ACLAnthologyBackend	ACL/EMNLP/NAACL papers

CLI Output

The CLI uses rich formatting for better readability:

• Tables for multiple papers showing source, year, title, and authors
• Panels for single paper details with full metadata
• Color coding for better visual separation
• Truncation for long titles and abstracts
