Assume you have two documents D1 = abccacab D2 = acacabca a.) Find the 2-shingles of both documents (hints: A 2-shingle is a k-shingle, with k = 2. Also, remember that sets cannot contain duplicates) b.) Find the Jaccard Similarity of D1 and D2 The question has been answered but isn’t the jaccard similarity 0.8 not 0.4? Isn’t (AUB)= 5 [ab, ca, bc, ac, cc] and (|A ∩ B|) = 4 [ab, bc, ca, ac] So: 4/5 = 0.8 Right? Because the sets cannot contain duplicates.

Intermediate SQL Concepts

A query is a request for data or information from one or more database tables. This information could be presented in the form of pictorials, graphs, or complicated findings which helps in easy interpretation. Structured Query Language (SQL) is the most widely used programming language for retrieving and organizing data from relational databases. Collection of tables with rows and columns is referred to as a database. SQL is the language of databases. It makes it easier to extract specific data from databases, which can then be used for analysis.
