## ✅ Issues Fixed

### 1. Import Conflict Fixed
- **File**: `text_similarity.py`
- **Issue**: Method name `cosine_similarity` conflicted with imported function
- **Fix**: Renamed import to `sklearn_cosine_similarity` to avoid conflict
- **Status**: ✅ FIXED

### 2. Unused Import Removed
- **File**: `text_preprocessing.py`
- **Issue**: `import string` was not being used
- **Fix**: Removed unused import
- **Status**: ✅ FIXED

### 3. Potential Bug Fixed
- **File**: `entity_recognition.py`
- **Issue**: `extract_locations` could fail if GPE returns None
- **Fix**: Wrapped in `list()` to ensure it's always a list
- **Status**: ✅ FIXED

### 4. Error Handling Enhanced
- **Files**: `nlp_pipeline.py`, `app.py`, `templates/index.html`
- **Issue**: Missing comprehensive error handling
- **Fix**: Added try-catch blocks, input validation, and error display
- **Status**: ✅ FIXED
