## 🔧 **Advanced Features**



### **Memory Management**



v0lur includes sophisticated memory management for processing large datasets:



```python

# Automatic memory monitoring

Memory usage [entity_extraction_start]: 595.2MB RSS, 3.6% of system

Memory usage [entity_extraction_after_gc]: 526MB RSS, 3.2% of system



# Configurable memory limits

max_memory_mb: 2048        # Hard limit (2GB)

memory_warning_mb: 1536    # Warning threshold (1.5GB)

cleanup_threshold_mb: 1024 # Auto-cleanup trigger (1GB)

```



### **Quote-Aware Processing**



Advanced speaker attribution prevents misattribution of quoted content:



```python

# Detects and handles:

# - Forwarded messages 

# - Quoted text spans

# - Multi-speaker messages

# - Reply contexts



Messages with quotes: 430/598 (71.9%)

Multi-speaker messages: 18/598 (3.0%) 

Average spans per message: 2.35

```



### **Topic Discovery**



Hybrid approach combining ontology classification with unsupervised discovery:



```yaml

# Ontology-based classification

topic_ontology: "config/topics.yaml"



# Unsupervised discovery  

bertopic_enabled: true

discovery_min_cluster_size: 10

discovery_max_topics: 50

ontology_mapping: true     # Map discovered topics to ontology

```



### **Performance Optimization**



Built-in optimizations for large-scale processing:



- **Batch Processing** - Configurable batch sizes for memory efficiency

- **Lazy Loading** - On-demand model loading to reduce startup time

- **Caching** - Intelligent caching of embeddings and intermediate results

- **Streaming** - Support for processing datasets larger than available memory

## 🐛 **Troubleshooting**



### **Common Issues**



#### **1. Bus Error 10 (macOS)**

**Fixed!** Memory-safe architecture eliminates this crash.

```bash

# If you encounter this in older versions:

python telegram_analyzer.py --memory-safe --memory-limit 1024

```



#### **2. Missing Dependencies**

```bash

# Install BERTopic stack

pip install bertopic>=0.15.0 hdbscan>=0.8.29 umap-learn>=0.5.3



# Install spaCy model  

python -m spacy download en_core_web_sm

```



#### **3. Memory Issues**

```bash

# Use memory-safe mode

python telegram_analyzer.py --memory-limit 1024 --input data/large_export.json



# Or enable checkpointing

python telegram_analyzer.py --checkpoint-interval 50 --input data/export.json

```



#### **4. UI Not Loading Data**

```bash

# Refresh run list

# Press 'r' in the UI, or:

python textual_ui.py --rescan

```



### **Debug Mode**

```bash

# Enable verbose logging

python telegram_analyzer.py --debug --input data/export.json



# Check processing logs

tail -f out/your_run/processing_log.txt

```

## 📊 **Performance Benchmarks**



### **Processing Speed** (MacBook Pro M2, 16GB RAM)

| Dataset Size | Processing Time | Memory Usage | Output Size |

|-------------|----------------|--------------|-------------|

| 1K messages | 2-3 minutes | ~500MB | ~50MB |

| 10K messages | 15-20 minutes | ~1GB | ~200MB |

| 100K messages | 2-3 hours | ~2GB | ~1.5GB |



### **Memory Safety** 

- **Before:** Bus Error 10 crashes on large datasets

- **After:** ✅ Stable processing of 100K+ messages with checkpoints



### **Fault Tolerance**

- **Checkpoint Creation:** Every 100 messages (configurable)

- **Resume Time:** <30 seconds from any checkpoint

- **Data Loss:** Zero (all progress saved)
