    A Review on NLP Techniques and Associated Challenges in Extracting Features from Education Data
    (International Journal of Computing and Digital Systems, 2024-08) Lukwaro, Elia; Kalegele, Khamisi; Nyambo, Devotha
    There has been a significant increase in academic processes to ensure the quality of educational resources such as curricula, examinations, and educational content. This has drawn attention to studies exploring the use of text mining, learning machines, and auto-analytic tools like natural language processing (NLP) to interpret and evaluate the quality of these educational resources. Auto-analytical techniques are required to evaluate the quality of educational content; otherwise, manual evaluation can be burdensome and improperly influenced by human instincts. This study employs a methodical approach to comprehensively survey NLP techniques for extracting syntactic and semantic features to analyze and comprehend educational content. NLP, in combination with machine learning, is an ideal tool for automatically evaluating the aspects of higher education quality. This is because they include features that aid in textual content comprehension as well as implementing natural language techniques that provide an interpretive interface between humans and machines. The review highlights the limitations of NLP in evaluating educational data, including the need for sentence-level understanding and the need for research to address challenges like noise in text data, domain-specific language variations, and improving model robustness for effective feature extraction in educational contexts. The findings of this review hold substantial benefits for various stakeholders, including education regulatory bodies, researchers, higher education institutions, and NLP researchers. Notably, the study equips NLP researchers with valuable insights into document analysis’s current strengths and weaknesses. The accumulated evidence can provide the skills to develop NLP-based applications for evaluating the relevant and quality aspects of education in higher educational settings. Furthermore, NLP researchers can be updated on the strengths and limitations of document analysis, allowing them to apply effective text representation approaches and implement the appropriate algorithm and techniques for NLP tasks, particularly in educational data.
