Introduction

When I was a college student, I used to call a part of my friend's name as an antonym for some reason.

Saigo Takamori → Togo Takamori
Ono no Imoko → Ono no Imoko

After repeating it several times, I fell in love with a friend's acupuncture points and laughed so much that I couldn't move. I wanted that friend to be happy for the first time in a long time, and I wanted to automate it (?), So I implemented it programmatically.

Convert some Japanese names to antonyms

Database

From LinkData, KeitarouNakayama has published "Antonym of one kanji character" ”was used. It is a public domain with 380 kinds of kanji (190 pairs).

Implementation

The code that implements the function looks like this:

import random
import re
import requests

JSON_URL = "http://linkdata.org/api/1/rdf1s3497i/antonym_rdf.json"
LABEL = "http://www.w3.org/2000/01/rdf-schema#label"
WORD = "http://ja.dbpedia.org/page/Chinese characters"
ANTONYM_WORD = "https://www.wikidata.org/wiki/Property:P461"

res = requests.get(JSON_URL)
data = res.json()

antonym_data = {}
for i in data:
  if i not in antonym_data:
      antonym_data[data[i][WORD][0]["value"]] = []
  antonym_data[data[i][WORD][0]["value"]].append(data[i][ANTONYM_WORD][0]["value"])

def be_antonyms_name(pure_name):
  antonym_name = ""
  for one_kanji in pure_name: 
    if one_kanji in antonym_data:
      antonym_name += random.choice(antonym_data[one_kanji])
    else :
      antonym_name += one_kanji
  return antonym_name

Run

Let's run it.

names = ["Oda Nobunaga", "Ryoma Sakamoto", "Saigo Takamori", "Minamoto no Yoritomo", "Ono no Imoko"]
for name in names:
  print(be_antonyms_name(name))

Nobutaka Oda
Sakasue Ryuneko
Ryu Togo
Gen Yoriyu
Ohno Sister

It has been converted correctly (?).

in conclusion

Please use it by all means! It can also be applied to sentences!
