Use Java to perform wordcount

 

The csv file below has three columns:

title,text,date

exampleTitle,This is is is an example example, April 2022

The 2nd Title,This this is an an example 4 K k,April 2023

Use Java to do this: Traverse each line to first output the 1st column, and then split the 2nd column as words and output the appearance frequency of each word. Numbers and single letters are not counted; only words with different cases are treated as individual words. Below is the expected result:

exampleTitle

an 1

example 2

is 3

this 1

The 2nd Title

an 2

example 1

is 1

this 2

Write the following SPL script:

A

B

1

for T("data.csv")

>output(A1.title)

2

=A1.text.words().(lower(~))

3

=B2.groups(~;count(1))

4

=B3.select(len(#1)>1)

5

>output(B4.export())

A1: Parse the csv file as a two-dimensional table and loop through each row.

B2: Split the text column to get words and convert them to lowercase.

B3: Count the appearances of every word.

B4: Get words having more than one character.
