    ### About This Research Interface

    **Translation Models**:
    - [megalaa/coptic-english-translator](https://huggingface.co/megalaa/coptic-english-translator) & [megalaa/english-coptic-translator](https://huggingface.co/megalaa/english-coptic-translator)
    - Based on work by Enis & Megalaa (2024)

    **Dependency Parser** (Neural-Symbolic Hybrid):
    - **Neural**: Stanza NLP pipeline + DiaParser for Coptic
    - **Symbolic**: Prolog implementation of Walter Till's Coptic grammar
    - **Lexicon**: Integration with Crum's Coptic Dictionary
    - **Error Detection**: Prolog validation catches neural parser hallucinations

    **Research Features**:
    - CoNLL-U format export for corpus analysis
    - Grammatical pattern detection (tripartite sentences, etc.)
    - Dialect-aware processing (Sahidic/Bohairic)
