ContenTube _{^{- The ultimate search engine for videos. No more clickbait!}}

By Dan and Jonathan

Information Retrieval (IR) Systems

• We implementetd the search feature using TF-IDF, a heuristic to determine and rank the best matches for a given input query.

• To determine how good our search engine is, we developed 3 independent IR systems to compare. They are based on:

  1. Title
  2. Description
  3. Content

Dataset

1. Ted Talks
2. Clickbait Videos and Podcasts

Final Demo

Evaluation

• We evaluated the success of our content based IR system in comparison to the other 2 IR systems. Metrics we used:
  • Order Unaware: Precision (P), Recall (R), Accuracy (A), F Measuree (F1 score)
  • Order Aware: Mean Reciprocal Rank (MRR), Average Precision (AP), Mean Average Precision (MAP), Cumulative Gain (CG), Discounted Cumulative Gain (DCG), Normalized Discounted Cumulative Gain (NDCG)
