In ananthajanakiraman/CSeqpat: Frequent Contiguous Sequential Pattern Mining of Text

Description

Takes in the filepath and minimum support and performs pattern mining

Usage

CSeqpat(filepath, phraselenmin = 1, phraselenmax = 99999, minsupport = 1,
  docdelim, stopword = FALSE, stemword = FALSE, lower = FALSE,
  removepunc = FALSE)

Arguments

filepath	Path to the text file/text corpus
phraselenmin	Minimum number of words in a phrase
phraselenmax	Maximum number of words in a phrase
minsupport	Minimum absolute support for mining the patterns
docdelim	Document delimiter in the corpus
stopword	Remove stopwords from the document corpus (boolean)
stemword	Perform stemming on the document corpus (boolean)
lower	Lower case all words in document corpus (boolean)
removepunc	Remove punctuations from document corpus (boolean)

Value

A dataframe containing the frequent phrase patterns with their absolute support

Examples

test1 <- c("hoagie institution food year road ",
"place little dated opened weekend fresh food")
tf <- tempfile()
writeLines(test1, tf)
CSeqpat(tf,1,2,2,"\t",TRUE,FALSE,TRUE,FALSE)
