Summary
I hope this chapter and the previous chapter on LSI helped you gain a comprehensive understanding of LSI. In this chapter, we learned how to build an LSI model in Gensim and deploy it as a search engine. We learned how to use the coherence score to find the optimal number of topics. Then, investigated the results of the final model to ensure a sound outcome. Finally, we applied the model to score new documents.
In the following chapter, we will learn about Latent Dirichlet Allocation (LDA). The techniques that we learned in this chapter will help you to learn LDA effectively.
