LSI (Latent Semantic Indexing)
- LSI enables to find relevant information when it shares no words with their queries.
- LSI considers transcripts that have words in common that are semantically close.
- LSI does not require an exact match to return useful results.
- Same example, search on “Chronobot” will return statements containing about “time-machine”, “virtual-classroom”,”DrChang”, ”Nocture”
