    Study Notes

    Language and Sound

    • Phonological analysis studies language at the sound level, focusing on distinct words identified by their morphemes, the smallest units of meaning.
    • Syntax in NLP examines the grammatical structure of sentences by analyzing how words are arranged and interact to form meaning.

    Word Formation and Semantics

    • Morphology relates to word formation, encompassing the combination of sounds into organized speech units.
    • Semantics focuses on the meaning of sentences derived from interactions among word-level meanings and the overall context they create.

    Core NLP Tasks

    • Core tasks in Natural Language Processing (NLP) include converting natural language text into structured numerical data.
    • Common NLP tasks may exclude those such as basic string manipulation, which doesn't involve complex language processing.

    Natural vs. Computer Languages

    • Natural languages differ from computer programming languages due to their complexity and ambiguity; they can't be directly translated into mathematical operations.
    • The term 'Corpus' refers to a collection of texts used as datasets in NLP methods.

    Discourse and Pragmatic Analysis

    • Discourse Integration analyzes interconnected sentences and the context that shapes their interpretation.
    • Pragmatic Analysis explains how additional meaning is inferred from text beyond the literal content, incorporating world knowledge and contextual intentions.

    NLP System Pipeline

    • The NLP system pipeline involves several stages, including feature extraction from natural language, planning responses, and generating text based on conversation history.
    • Once structured data is extracted, it can be used for various applications, including machine learning for language understanding.

    Contextual Understanding

    • Understanding contextual aspects of meaning is crucial in NLP, as it takes into account how previous sentences influence the interpretation of current sentences.
