Jamdict is used in Jamdict-web - a web-based free and open-source Japanese reading assistant software. Please try out the demo instance online at:

https://jamdict.herokuapp.com/

There also is a demo Jamdict virtual machine online for trying out Jamdict Python code on Repl.it:

Installation

Jamdict & Jamdict database are both available on PyPI and can be installed using pip

pip install --upgrade jamdict jamdict-data

Sample jamdict Python code

from jamdict import Jamdict
jam = Jamdict()

# use wildcard matching to find anything starts with 食べ and ends with る
result = jam.lookup('食べ%る')

# print all word entries
for entry in result.entries:
     print(entry)

# [id#1358280] たべる (食べる) : 1. to eat ((Ichidan verb|transitive verb)) 2. to live on (e.g. a salary)/to live off/to subsist on

Using KRAD/RADK mapping

Jamdict has built-in support for KRAD/RADK (i.e. kanji-radical and radical-kanji mapping). The terminology of radicals/components used by Jamdict can be different from else where.

  • A radical in Jamdict is a principal component, each character has only one radical.
  • A character may be decomposed into several writing components.

By default jamdict provides two maps:

  • jam.krad is a Python dict that maps characters to list of components.
  • jam.radk is a Python dict that maps each available components to a list of characters.
# Find all writing components (often called "radicals") of the character 雲
print(jam.krad['雲'])
# ['一', '雨', '二', '厶']

# Find all characters with the component 鼎
chars = jam.radk['鼎']
print(chars)
# {'鼏', '鼒', '鼐', '鼎', '鼑'}

# look up the characters info
result = jam.lookup(''.join(chars))
for c in result.chars:
    print(c, c.meanings())
# 鼏 ['cover of tripod cauldron']
# 鼒 ['large tripod cauldron with small']
# 鼐 ['incense tripod']
# 鼎 ['three legged kettle']
# 鼑 []

Finding name entities

# Find all names with 鈴木 inside
result = jam.lookup('%鈴木%')
for name in result.names:
    print(name)

# [id#5025685] キューティーすずき (キューティー鈴木) : Kyu-ti- Suzuki (1969.10-) (full name of a particular person)
# [id#5064867] パパイヤすずき (パパイヤ鈴木) : Papaiya Suzuki (full name of a particular person)
# [id#5089076] ラジカルすずき (ラジカル鈴木) : Rajikaru Suzuki (full name of a particular person)
# [id#5259356] きつねざきすずきひなた (狐崎鈴木日向) : Kitsunezakisuzukihinata (place name)
# [id#5379158] こすずき (小鈴木) : Kosuzuki (family or surname)
# [id#5398812] かみすずき (上鈴木) : Kamisuzuki (family or surname)
# [id#5465787] かわすずき (川鈴木) : Kawasuzuki (family or surname)
# [id#5499409] おおすずき (大鈴木) : Oosuzuki (family or surname)
# [id#5711308] すすき (鈴木) : Susuki (family or surname)
# ...

Exact matching

Use exact matching for faster search.

Find the word 花火 by idseq (1194580)

>>> result = jam.lookup('id#1194580')
>>> print(result.names[0])
[id#1194580] はなび (花火) : fireworks ((noun (common) (futsuumeishi)))

Find an exact name 花火 by idseq (5170462)

>>> result = jam.lookup('id#5170462')
>>> print(result.names[0])
[id#5170462] はなび (花火) : Hanabi (female given name or forename)
