Compute the vocabulary size M for this scenario: Looking at a collection of web pages, you find that there are 3000 different terms in the first 10,000 tokens and 30,000 different terms in the first 1,000,000 tokens. Assume a search engine indexes a total of 20,000,000,000 (2 × 1010) pages, containing 200 tokens on average What is the size of the vocabulary of the indexed collection as predicted by Heaps’ law?
