How can we best estimate the amount of time a keyword is discussed in a course?

  • Frequency.py results for keyword “probability”:

The function loads the lecture transcripts for a specific MADS course (using the course ID) from the database. Each function estimates the keyword’s frequency using different algorithms

  • Improve the search engine by including multiple word phrases as keywords, and integrating related terms
  • Add features such as sort by relevance or importance
  • Implement LearningClues in classrooms and get feedback from instructors and students

CLUE: Contextual Linkaging for Undergraduate Education

INTRODUCTION

The LearningClues project consists of a database of class sessions, utilizing Natural Language Processing to analyze the lecture's transcripts to identify words and phrases that are mentioned in class. It plays a key role in the students' learning environment as links are automatically generated between the keywords and phrases that refer to specific instances in the course textbook, articles, other activities and educational resources. This learning aid makes access to relevant information more readily available as the search engine provides further support and improves studying efficiency. Think Google for the classroom. This solution will give academic institutions a mechanism to dynamically link learning tools according to context, increasing the quality and effectiveness of their current curriculum.

TASK OVERVIEW

FUTURE DIRECTIONS

  • Work through the coursera-dl library
  • Download, format and upload MADS (Masters of Applied Data Science) course lectures
  • Research various search engine APIs and NLP algorithms and relevant packages (NumPy, NLTK, PyTerrier)
  • Create a word frequency and time approximation function (frequency.py)
  • Test the accuracy and efficiency of frequency.py using MADS course videos
