Minilexical

Minilexical refers to a minimalist approach to lexical representation, often used in computational linguistics and natural language processing (NLP). The concept emphasizes the use of the smallest possible set of linguistic units—such as morphemes, word stems, or even single characters—to capture the essential meaning or syntactic role of words in a text. This method is particularly useful in resource-constrained environments, where computational power or storage is limited, or when working with low-resource languages lacking extensive linguistic annotations.

The term "minilexical" contrasts with traditional lexical approaches that rely on full word forms, inflected forms, or rich morphological analyses. By focusing on minimal units, systems can achieve greater efficiency without sacrificing core functionality. For example, in morphological analysis, minilexical methods might break down words into their root morphemes rather than preserving all inflections, reducing the computational load while still enabling accurate parsing.

Minilexical techniques are commonly applied in tasks such as part-of-speech tagging, named entity recognition, and machine translation, especially in multilingual settings. They are also employed in the development of lightweight language models and dictionaries for under-resourced languages. The approach aligns with broader trends in NLP toward simplicity, scalability, and adaptability, making it a valuable tool in both research and practical applications.

While minilexical methods prioritize efficiency, they may sometimes sacrifice precision in capturing nuanced linguistic distinctions. However, their trade-offs are often justified by the need for practicality in real-world systems. The concept remains an active area of study, with ongoing research exploring ways to balance minimalism with accuracy in lexical representation.
