Word to Number i18n

Convert number words from different languages with Python, CSharp or Java API eg. three hundred and forty two to numbers (342) or vingt-et-un (21) or две целых три десятых (2.3).Word2Number-i18n convert number words (eg. twenty one) to numeric digits (21). Below is the installation, usage and other details of this module.

Fun with numbers

• French: We can calculate! So 4*20+10 are 90 and this is normal (quatre-vingt-dix).
• German: We have our own rules. All under million is one word (but often false written) and also we say for 21 onetwenty (einunzwanzig) not twenty one.
• Spanish: Less is more, we need no word for 1.000.000.000 as word an says mil millón (for example tres mil millones).

Supported natural languages

• English
• French
• Portugues
• Russian
• Slovak
• Spanish

Request new language

Do follow steps

1. check your request (directory data), textfile name ISO-639-1 code
2. if not found check ISO-639-3 code
3. if not found create new file with new ISO-639-1/3 code

Example

You want to tranfer NLP CARD to numeric value for Lower Sorbian. German (de) isn't it. You do not found an ISO-639-1 code, you do not found an ISO-639-1 file for dsb extension. You create a new file number_system_dsb.txt with utf-8 encoding

null=0
jaden=1
dwa=2
tśi=3
styri=4
pěś=5
šesć=6
sedym=7
wósym=8
źewjeś=9
źaseś=10

Every config file need the values from zero to nine and every supported language need a config file.

And add all single words with values. In extensions you need also value for point and additional replacement words and measure words in the same configuration file. Its different to value names where the key is localized now the key is internal used and parts or full predefined. Feel free to copy a existing language config.

Example:

# 0-9
# much more
twenty=20
thousand=1000
# special
point=komma
replace:what=with
replace:две=два
replace:dozen=twelfe
replace:gran=thousand
measure:aLotOf=1000
measure:namesAreLikeIceOnMadeira=1000000

The point is elementary to work with decimal values and this value is the word in your language. The measure are the multiplier for the numbers. It extends the numeric value with an label or like NLP with an tag. So the name thousand is the name for the numeric value and a gran are a synonym for thousand and thousand is a measure word.

So giving twenty nice gran do the follow:

1. word2number-i18n register initial value 1000 as measure. The name aLotOf is your comment.
2. word2number-i18n looking for replace and change text to twenty nice thousand
3. word2number-i18n filter none number words to trash and your text is twenty thousand
4. word2number-i18n find out 1000 is a measure and the localized name is thousand. In result of this thousand is here a multiplier for the numeric value before.
5. word2number-i18n take the numeric value 20 instead of twenty and the multiplier after to give your the result 20000

Internal much more especially checks inside working.

Supported programming languages

Python

Please note that these Python implementation is similar to Java and CSharp.

Installation

Please ensure that you have updated pip to the latest version before installing word2number-i18n.

You can install the module using Python Package Index using the below command.

    pip3 install word2number-i18n 

Installation from source

On macOS

    # git clone https://github.com/bastie/w2ni18n.git w2n
    # python3 setup.py install

Make sure you install all requirements given in requirements.txt

    pip3 install -r requirements.txt

Usage

Add the word2number-i18n to requirements.txt in your project. First you have to import the module using the below code.

from word2numberi18n import w2n

Then you can use the word_to_num method to convert a number-word to numeric digits, as shown below.

print(w2n.word_to_num("two million three thousand nine hundred and eighty four"))
2003984

print(w2n.word_to_num('two point three')) 
2.3

print(w2n.word_to_num('one hundred thirty-five')) 
135

print(w2n.word_to_num('million million'))
Error: Redundant number! Please enter a valid number word (eg. two million twenty three thousand and forty nine)
None

print(w2n.word_to_num('blah'))
Error: No valid number words found! Please enter a valid number word (eg. two million twenty three thousand and forty nine)
None

i18n

word2number looking for your specific language with

1. given parameter for language and if not found
2. defined environment variable w2n.lang with ISO lang code like en, hi, de and if not found
3. over locale.getdefaultlocale() and if not found
4. over environment variable "LANGUAGE" and if not found
5. fallback to english 

In result use it classic Python like (example unit_testing_ru.py):

os.environ['w2n.lang'] = 'ru'
w2n.word_to_num('две целых три десятых')

Also work with object oriented Python like (example unit_testing_fr.py):

instance = w2n.W2N(lang_param="fr")
instance.word_to_num('trente-et-un')

Place in the data directory your language specific dictionary file with ISO lang code in the name.

    Locale.setDefault(Locale.CANADA);
    W2N english = new W2N();
    System.out.println(english.wordToNum("three hundred fifty"));

    Locale.setDefault(Locale.CANADA_FRENCH);
    W2N french = new W2N();
    System.out.println(french.wordToNum("vingt et un"));
    
    System.out.println(english.wordToNum("three point one four"));

In result it prints

350
21

Bugs/Errors

• german language need more specific algorithm

w2n fixed

• Add regex to fix comma bug fixed by jnelson16
• fixed floating point conversation bug
• accept also number values because it is more understandable to handle str:112 as same as int:112
