Subset Sequence Frequency in Set

No algorithm description given

Fast Algorithm to compute the most common prefixes in a large dataset.  AKA "Starting Pattern Occurrence Frequency " Results ranked by the most common. Applications: Next letter prediction Word completion DNA sequencing Protein sequencing Computational linguistics Compression algorithms Optional parameters: minScore - result frequency cutoff [default: 2] minLength - minimum prefix length [default: 1] startsWith - fixed prefix filter, useful for predictions (not used by default) maxResults - return at most this many results (by default return all matching) Examples: { "minLength": 4, "maxResults": 10, "dataset": ["John", "William", "James", "Charles", "George", "Frank", "Joseph", ...] }  Returns the top10 Baby Name prefixes, minimum length 4, from a 20th century US Baby Names list (2.5Mb), example dataset trimmed, result: {"Mari": 1941, "Fran": 1420, "Chris": 1227, "Chri": 1227, "Juli": 1167, "Will": 1151, "Char": 1066, "Christ": 1057, "Marg": 1041, "Kath": 983} Sample input and output against a "buzzwords" list:
