    Semantic Similarity Metric

    Calculates semantic similarity between text fields extracted from the event
    by leveraging OpenAI embeddings. Compares event["outputs"]["content"] with
    event["feedback"]["ground_truth"] to produce a similarity score.

    This implementation uses a dot-product similarity on embeddings obtained 
    from the "text-embedding-3-small" model. 

    Score range:
        0.0 to 1.0 (though it can slightly exceed this depending on embedding behavior),
        where higher values indicate closer semantic similarity.

    Args:
        event (dict): 
            - event["outputs"]["content"] (str): The model's output text.
            - event["feedback"]["ground_truth"] (str): The reference or ground truth text.

    Returns:
        float: A similarity score between 0.0 and 1.0. Returns 0.0 if there's an error 
               or if either string is empty.
