CHASEN(1)

💖 CHASEN — Japanese Morphological Analysis System 💖

okay bestie, sit down, hydrate, and let me tell you about chasen, a whole morphological analysis system from the General Commands Manual, section 1. she's iconic, she's academic, she segments Japanese text and she does NOT miss. let's go 🎀

✨ SYNOPSIS ✨

chasen [options] file

🌸 DESCRIPTION 🌸

so like, chasen is a morphological analysis system. what does that mean for us? it can segment and tokenize a Japanese text string, and it can output that with a TON of extra info attached — pronunciation, semantic information, and others. it's giving linguist main character energy fr fr 🧚

and the way it works? it prints the result of all that to standard output, so you can either write it to a file or keep processing it downstream. flexible queen behavior 💅

👑 OPTIONS 👑

here's the full roster, no skips, no cuts, we respect every flag in this house 🫶

• -s — use partial sentence mode for analysis.
• -j — use Japanese sentence mode for analysis. KUTEN (including other puncuation marks) and empty line are treated as the punctuation of the text.
• -C — use the command mode for analysis.
• -b — show the best path. (this one's the default, she's the baseline 💖)
• -m — show all morphemes where ambiguity is identified in the best path.
• -p — show all paths expanding for all combinations of the ambiguity. (all of them. every single one. brace yourself 😭)
• -f — show formatted morpheme data in column. (default ✨)
• -e — show entire morpheme data.
• -c — show coded morpheme data.
• -d — show detailed morpheme for use by Prolog.
• -v — show detailed morpheme for use by VisualMorphs.

• -Fh — print help information for -F option.
• -i lang — specify the character encoding of the input file. e: EUC-JP, s:Shift JIS, w:UTF-8, u:UTF-8, a:ISO-8859-1
• -o file — specify the output file to be file .
• -w width — specify the cost width.
• -r rcfile — use rcfile as the chasenrc file.
