# ============================================================================
# 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.
