Semantic Scholar Lookup

Fast, targeted lookups of paper metadata, citations, and authors using the Semantic Scholar API via `asta papers` commands.

When to Use This Skill

• User asks for details about a specific paper (by title, DOI, arXiv ID, etc.)
• User wants to see papers citing a given work
• User asks about an author's papers
• User wants a quick keyword search (not a comprehensive report)
• Task requires targeted paper metadata or citation graphs

Not for comprehensive reports - use the Literature Report Generation skill for that.

Installation

This skill requires the asta CLI:

# Install/reinstall at the correct version
PLUGIN_VERSION=0.14.0
if [ "$(asta --version 2>/dev/null | grep -oE '[0-9]+\.[0-9]+\.[0-9]+')" != "$PLUGIN_VERSION" ]; then
  uv tool install --force git+https://github.com/allenai/asta-plugins.git@v$PLUGIN_VERSION
fi

Prerequisites: Python 3.11+ and uv package manager

asta papers author search "Hinton" --limit 5 --format text

asta papers author papers - Get papers by an author

# First, get author ID from search

# Then get their papers using the author ID
asta papers author papers 1741101 --limit 50

asta papers author papers 1741101 --fields title,year,venue,citationCount

Options:

• --fields: Fields to return for papers
• --limit: Max results (default 50, max 1000)
• --format: Output as json or text

Output Formats

All commands support two output formats:

JSON format (default):

• Machine-readable
• Complete data structure
• Pipe to jq for filtering
• Best for programmatic use

Text format (--format text):

• Human-readable
• Formatted output
• Best for quick browsing
• Use when showing results to user

Usage Tips

Efficient Field Selection

Only request fields you need for faster responses:

# Good - minimal fields for quick browse
asta papers search "deep learning" --fields title,year,authors,citationCount

# Less efficient - many fields slow down response
asta papers search "deep learning" --fields title,abstract,authors,year,venue,citations,references

Year Filtering

Restrict to recent papers when appropriate:

asta papers search "RLHF" --year 2023-2024  # 2023-2024
asta papers search "RLHF" --year 2023-      # 2023 onwards
asta papers search "RLHF" --year -2020      # Before 2020

Piping to jq

For complex JSON processing:

# Extract just titles
asta papers search "transformers" | jq '.data[].title'

# Filter by citation count
asta papers search "neural networks" | jq '.data[] | select(.citationCount > 100)'

# Get author names
asta papers get ARXIV:2005.14165 | jq '.authors[].name'

Multi-Step Workflows

Chain commands for complex queries:

Example 1: Find highly-cited recent papers by an author

# 1. Find author
asta papers author search "Geoffrey Hinton" --format text

# 2. Get their recent papers
asta papers author papers 1751273 --fields title,year,citationCount --limit 50 | \
  jq '.data[].paper | select(.year >= 2020) | select(.citationCount > 100)'

Example 2: Explore citation network

# 1. Get paper details
asta papers get ARXIV:2005.14165

# 2. Get who cited it
asta papers citations ARXIV:2005.14165 --limit 20 --format text

# 3. Get details on specific citing papers
asta papers get CorpusId:123456789

Example Workflows

"Get details for arXiv:2005.14165"

asta papers get ARXIV:2005.14165 --format text

Present the output to user in a readable format.

"What papers cite the GPT-3 paper?"

# GPT-3 paper
asta papers citations ARXIV:2005.14165 --limit 50 --format text

Show recent/highly-cited papers from the results.

"Recent papers on RLHF"

asta papers search "RLHF reinforcement learning from human feedback" \
  --year 2023- \
  --limit 20 \
  --fields title,abstract,year,authors,venue,citationCount \
  --format text

"Papers by Yoav Goldberg"

# Step 1: Find author
asta papers author search "Yoav Goldberg" --format text

# Step 2: Get their papers (using author ID from step 1)
asta papers author papers 1741101 \
  --fields title,year,venue,citationCount \
  --limit 50 \
  --format text

"Find evidence of 'chain-of-thought' reasoning"

# Search for papers discussing this
asta papers search "chain-of-thought reasoning" \
  --fields title,abstract,year,authors \
  --limit 15

# Then examine specific papers with 'asta papers get'

1. **Paper Title** - Author et al. (Year) - [Venue] - [X citations]
2. **Another Paper** - ...
...

For citations:

Found [N] papers citing this work:

Recent citations:

2. [Paper 2] (2023) - [citations]
...

Best Practices

• Use --format text when showing results directly to user
• Use JSON output when you need to process or filter results
• Start with small limits, increase if needed
• Only fetch fields you'll actually use
• For comprehensive research, suggest Literature Report Generation skill instead
• Provide Semantic Scholar URLs when helpful (https://semanticscholar.org/paper/{paperId})

API Key

The commands use the ASTA_TOOL_KEY environment variable if available. Most queries work without a key, but a key provides higher rate limits.
