What is Boolean Retrieval in Information Retrieval about?
The Boolean model is the simplest model for information retrieval systems. Queries are Boolean expressions and documents are returned if they satisfy the Boolean expression. Terms and documents are represented using an inverted index and 0/1 vectors. An inverted index stores a list of documents for each term. To evaluate queries, the corresponding term vectors are combined using bitwise operations. This representation is more efficient than a term-document matrix for large collections due to sparsity.
