add_wchnstr - Linux
Overview
add_wchnstr is a lightweight utility for adding word chains to a given text file. It’s primarily used in natural language processing (NLP) tasks, such as text generation, language modeling, and text analysis. The word chains it adds are created using a Markov chain model.
Syntax
add_wchnstr [OPTIONS] FILE
Options/Flags
- -o, –output-file
: Specifies the output file name. Defaults to stdout (console). - -n, –order
: Sets the Markov chain order. Defaults to 2. - -k, –min-freq
: Sets the minimum frequency for a word to be included in the chain. Defaults to 2. - -m, –max-chain
: Specifies the maximum length of the added word chains. Defaults to 5. - -d, –delimiter
: Sets the delimiter used to separate words in the chain. Defaults to " ". - -h, –help: Displays help information.
Examples
Add word chains of order 3 with a minimum frequency of 3:
add_wchnstr -n 3 -k 3 input.txt
Save output to a file with a delimiter of "_":
add_wchnstr -o output.txt -d "_" input.txt
Common Issues
- Ensure that the input file contains plain text.
- Adjust the Markov chain order and minimum frequency based on the specific needs of the task.
Integration
Combine with grep to extract specific chains:
add_wchnstr -m 5 input.txt | grep "the cat"
