Focused crawls are collections of frequently-updated webcrawl data from narrow (as opposed to broad or wide) web crawls, often focused on a single domain or subdomain.
Informative and comprehensive subject word lists provide a wealth of material connected with many entry words.
Lists included are famous people such as actors, artists, composers, politicians, and writers, all arranged by occupations, and geographical information such as countries, capitals, currencies, and political parties, arranged by subject. It is therefore a source of invaluable information for solving general-knowledge clues in crosswords and puzzles, and for boosting home study.
