CSeqpat {CSeqpat}

Mining Frequent Contiguous Sequential Patterns in a Text Corpus

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)
