# THINK KB Implementation Summary
|
|
|
|
## What Was Implemented
|
|
|
|
### 1. Core Functionality
|
|
- **File**: `botserver/src/basic/keywords/think_kb.rs`
|
|
- **Purpose**: Explicit knowledge base reasoning with structured results
|
|
- **Syntax**: `results = THINK KB "query"`
|
|
|
|
### 2. Key Features
|
|
- **Structured Results**: Returns detailed JSON object with results, confidence, and metadata
|
|
- **Confidence Scoring**: Calculates confidence based on relevance, result count, and source diversity
|
|
- **Multi-KB Search**: Searches all active knowledge bases in parallel
|
|
- **Token Management**: Respects token limits (default 2000 tokens)
|
|
- **Error Handling**: Comprehensive error handling with meaningful messages
|
|
|
|
### 3. Return Structure
|
|
```json
|
|
{
|
|
"results": [
|
|
{
|
|
"content": "Relevant text content",
|
|
"source": "document.pdf",
|
|
"kb_name": "knowledge_base_name",
|
|
"relevance": 0.85,
|
|
"tokens": 150
|
|
}
|
|
],
|
|
"summary": "Brief summary of findings",
|
|
"confidence": 0.78,
|
|
"total_results": 5,
|
|
"sources": ["doc1.pdf", "doc2.md"],
|
|
"query": "original search query",
|
|
"kb_count": 2
|
|
}
|
|
```
|
|
|
|
### 4. Integration Points
|
|
- **Keywords Module**: Added to `botserver/src/basic/keywords/mod.rs`
|
|
- **BASIC Engine**: Registered in `botserver/src/basic/mod.rs`
|
|
- **Feature Flag**: Protected by `vectordb` feature flag
|
|
- **Dependencies**: Uses existing KB infrastructure (KbContextManager, KnowledgeBaseManager)
|
|
|
|
### 5. Documentation
|
|
- **ALWAYS.md**: Comprehensive documentation with examples and best practices
|
|
- **BotBook**: Added `botbook/src/04-basic-scripting/keyword-think-kb.md`
|
|
- **Summary**: Added to `botbook/src/SUMMARY.md`
|
|
|
|
### 6. Testing
|
|
- **Unit Tests**: Added tests for confidence calculation, summary generation, and JSON conversion
|
|
- **Test Script**: Created `/tmp/think_kb_test.bas` for manual testing
|
|
|
|
## Key Differences from USE KB
|
|
|
|
| Feature | USE KB (Automatic) | THINK KB (Explicit) |
|
|
|---------|-------------------|-------------------|
|
|
| **Trigger** | Automatic on user questions | Explicit keyword execution |
|
|
| **Control** | Behind-the-scenes | Full programmatic control |
|
|
| **Results** | Injected into LLM context | Structured data for processing |
|
|
| **Confidence** | Not exposed | Explicit confidence scoring |
|
|
| **Filtering** | Not available | Full result filtering and processing |
|
|
|
|
## Usage Examples
|
|
|
|
### Basic Usage
|
|
```basic
|
|
USE KB "policies"
|
|
results = THINK KB "What is the remote work policy?"
|
|
TALK results.summary
|
|
```
|
|
|
|
### Decision Making
|
|
```basic
|
|
results = THINK KB "database error solutions"
|
|
IF results.confidence > 0.8 THEN
|
|
TALK "Found reliable solution: " + results.summary
|
|
ELSE
|
|
TALK "Need to escalate to technical support"
|
|
END IF
|
|
```
|
|
|
|
### Multi-Stage Reasoning
|
|
```basic
|
|
general = THINK KB "machine learning applications"
|
|
IF general.confidence > 0.6 THEN
|
|
specific = THINK KB "deep learning " + general.results[0].content.substring(0, 50)
|
|
TALK "Overview: " + general.summary
|
|
TALK "Details: " + specific.summary
|
|
END IF
|
|
```
|
|
|
|
## Benefits
|
|
|
|
1. **Explicit Control**: Developers can programmatically control KB searches
|
|
2. **Structured Data**: Results can be processed, filtered, and analyzed
|
|
3. **Confidence Scoring**: Enables confidence-based decision making
|
|
4. **Multi-KB Support**: Searches across all active knowledge bases
|
|
5. **Performance Aware**: Respects token limits and provides performance metrics
|
|
6. **Error Resilient**: Comprehensive error handling and fallback strategies
|
|
|
|
## Next Steps
|
|
|
|
1. **Integration Testing**: Test with real knowledge bases and documents
|
|
2. **Performance Optimization**: Monitor and optimize search performance
|
|
3. **Advanced Features**: Consider adding filters, sorting, and aggregation options
|
|
4. **UI Integration**: Add THINK KB support to the web interface
|
|
5. **Documentation**: Add more examples and use cases to the documentation
|
|
|
