# ============================================================================
# GERMAN LINGUISTICS HUB (CONSOLIDATED APP V22)
#
# This script combines multiple NLP tools into a single Gradio interface.
#
# ============================================================================
# TABS & FUNCTIONALITY:
# ============================================================================
#
# --- PRIMARY TABS ---
#
# 1. Word Encyclopedia (DE):
#    - NON-CONTEXTUAL analysis of single words.
#    - Multi-engine dispatcher with user selection and automatic fallback:
#      (Wiktionary -> DWDSmor -> HanTa -> IWNLP)
#    - Aggregates all grammatical (Wiktionary, Pattern) and semantic 
#      (Wiktionary, OdeNet, ConceptNet) possibilities, grouped by Part-of-Speech.
#    - Validates and filters artifacts (e.g., "abgeschnitten", "lauf").
#
# 2. Comprehensive Analyzer (DE):
#    - CONTEXTUAL analysis of full sentences.
#    - Uses the Word Encyclopedia's dispatcher for robust lemma analysis.
#    - Ranks all semantic senses (Wiktionary, OdeNet) by relevance to the sentence.
#
# --- STANDALONE TOOL TABS ---
#
# 3. spaCy Analyzer (Multi-lingual): 
#    - Direct, raw spaCy output (NER, POS, dependencies) for multiple languages.
#
# 4. Grammar Check (DE): 
#    - Direct LanguageTool output.
#
# --- RAW ENGINE TABS (for debugging & comparison) ---
#
# 5. Engine: Wiktionary (DE): 
#    - Standalone access to the Wiktionary DB (Primary) engine.
#
# 6. Engine: DWDSmor (DE):
#    - Standalone access to the DWDSmor (Fallback 1) engine.
#
# 7. Engine: HanTa (DE):
#    - Standalone access to the HanTa (Fallback 2) engine.
#
# 8. Engine: IWNLP-spaCy (DE):
#    - Standalone access to the IWNLP-spaCy (Fallback 3) engine.
#
# --- RAW COMPONENT TABS (for debugging & comparison) ---
#
# 9. Component: Inflections (DE): 
#    - Direct access to the `pattern.de` library.
#
# 10. Component: Thesaurus (DE): 
#     - Direct access to the `OdeNet` library.
#
# 11. Component: ConceptNet (Direct): 
#     - Direct access to the ConceptNet API.
