Recipe Objective: What is a corpus in Gensim?

A corpus is an extensive and well-structured collection of texts that a machine can read. A corpus is a collection of document objects in Gensim, and Corpora are the plural of the corpus. It serves the following roles in Gensim:

  It serves as an input for training a Model. The models use this training corpus to look for common themes and topics during training, initializing their internal model parameters. Gensim focuses on unsupervised models so that no human intervention, such as costly annotations or tagging documents by hand, is required.

  Documents to organize. The model can then be used to extract topics from new texts once trained. The new documents here were not used during the training period. Corpora can also be indexed for Similarity Queries.

A sample corpus can be found here. It comprises five documents, each of which is made up of a single sentence. The preceding sample loads the entire corpus into memory. However, corpora may be massive in practice, making memory loading unfeasible. Gensim handles such corpora by streaming them one document at a time.

"Find end-to-end projects at ProjectPro",
"Stop wasting time on 10 different online forums to get your project solutions",
"Each of our projects solve a real business problem from start to finish",
"All projects come with downloadable solution code and explanatory videos",
"All our projects are designed modularly so you can rapidly learn and reuse modules"]

This is just a tiny sample of a corpus for demonstration reasons. Another example would be a list of all blogs on a website, or a list of all the books written by J.K. Rowling, etc.
