Integration with research-assistant

note-processor works with the same database as research-assistant (research_db.json).

Typical Workflow

# 1. Add research notes
research_organizer.py add "new-topic" "Research finding here" "tag1" "tag2"

# 2. Add more notes over time
research_organizer.py add "new-topic" "Another finding" "tag3"

# 3. Summarize when done
note_processor.py summarize new-topic

# 4. Find specific information
note_processor.py extract new-topic keyword

# 5. See all topics
note_processor.py list

Using Both Together

# Research phase
research_organizer.py add "experiment" "Test result 1" "testing"
research_organizer.py add "experiment" "Test result 2" "testing"
research_organizer.py add "experiment" "Conclusion: worked!" "results"

# Analysis phase
note_processor.py summarize experiment
note_processor.py keywords experiment

# Writing phase
note_processor.py extract experiment conclusion
# Now write report based on extracted notes

Key Point Detection

The summarize command detects key points by finding sentences with important words:

• important, key, critical, essential
• must, should, note, remember
• warning, priority, critical

This helps surface actionable insights from your research.

Keyword Extraction

The keywords command:

• Filters words shorter than 4 characters
• Removes common stop words
• Counts frequency across all notes
• Shows top 20 keywords

Stop words filtered: that, this, with, from, have, been, will, what, when, where, which, their, there, would, could, should, about, these, those, other, into, through

Use Cases

Before Writing a Report

# Get overview
note_processor.py summarize research-topic

# Find specific data points
note_processor.py extract research-topic metrics

# Extract themes
note_processor.py keywords research-topic

Reviewing Research Progress

# See what you've been working on
note_processor.py list

# Check a specific topic's progress
note_processor.py summarize current-project

# Find patterns
note_processor.py keywords current-project

Finding Specific Information

# Search across a topic
note_processor.py extract income-experiments monetization

# Find references to specific tools
note_processor.py extract security-incident path-validation

# Locate conclusions
note_processor.py extract experiment conclusion

Best Practices

1. Use summaries - Get overview before diving into details
2. Search first - Use extract before reading all notes
3. Check keywords - Find themes you might have missed
4. List regularly - Review all topics to see gaps
5. Tag consistently - Makes keywords more meaningful

Data Location

Database: ~/.openclaw/workspace/research_db.json Format: Compatible with research-assistant skill

Limitations

• Simple keyword extraction - Frequency-based, not semantic
• No NLP - Basic text processing (no ML/AI)
• Stop word list - English-focused, customize for other languages
• Key point detection - Pattern-based, not understanding-based

Tips

For Better Keywords

• Use consistent terminology in your notes
• Avoid abbreviations or synonyms for the same concept
• Tag notes with important terms
• Review keywords to see if important terms appear

For Better Summaries

• Write complete sentences in notes
• Include important words (key, critical, must, etc.)
• Tag notes with themes
• Regularly summarize to track progress

For Better Search

• Use specific keywords in extract
• Search for related terms (synonyms)
• Check tags in results
• Use summaries to find the right topic

Troubleshooting

"Topic not found"

Topic 'x' not found.

Solution: Check topic name spelling. Use note_processor.py list to see all topics.

"No matches found"

No matches for 'keyword' in topic 'x'

Solution: Try different keywords, check spelling, use note_processor.py keywords to find related terms.

Poor keyword results

Top Keywords are mostly common words

Solution:

• Use more specific terms in your notes
• Tag notes with important terms
• The stop word filter can be customized in the code
