Python uses Fuzzywuzzy to convert Chinese characters into pinyin for matching
Preparation work:
Before using Fuzzywuzzy for pinyin matching, it is necessary to first install the relevant libraries. The specific steps are as follows:
Firstly, you need to install Python's Pinyin library pypinyin. You can use the pip command for installation:
pip install pypinyin
2. Next, you need to install the Fuzzywuzzy library. You can also use pip for installation:
pip install fuzzywuzzy
Note: If you are using Python version 3. x, please use the fork version of the fuzzywuzzy library, fuzzywuzzy [speedup], to improve performance.
Class library introduction:
1. pypinyin: is a Python pinyin conversion library used to convert Chinese characters into pinyin. It supports multiple pinyin styles and can set the format of the returned results.
2. fuzzywuzzy: It is a Python library based on fuzzy string matching algorithms. It uses the Levenshtein Distance algorithm to calculate the similarity between two strings, thereby achieving fuzzy matching.
Data sample:
To demonstrate the functionality of pinyin matching, we need to prepare some data samples for testing. Here is an example:
python
data = {
Zhang San:,
Li Si,
Wang Wu,
Zhao Liu,
Qian Qi
}
Sample code:
python
from fuzzywuzzy import fuzz
from fuzzywuzzy import process
from pypinyin import pinyin, Style
data = {
Zhang San:,
Li Si,
Wang Wu,
Zhao Liu,
Qian Qi
}
def convert_to_pinyin(name):
"""
Convert Chinese characters to pinyin
"""
pinyin_list = pinyin(name, style=Style.NORMAL)
return ''.join([item[0] for item in pinyin_list])
def fuzzy_match(query):
"""
Using Fuzzywuzzy for Fuzzy Matching
"""
result = process.extractOne(query, data.keys(), scorer=fuzz.ratio)
return data[result[0]]
#Example call
Input_ Name='Zhang San'
pinyin_name = convert_to_pinyin(input_name)
matched_name = fuzzy_match(pinyin_name)
Print (f 'Enter name: {inputname}')
Print (f 'Matched name: {matchedname}')
Summary:
This article introduces the preparation and implementation steps for using Fuzzywuzzy for pinyin matching. Firstly, you need to install pypinyin and fuzzywuzzy libraries. Then, use pypinyin to convert Chinese characters into pinyin, and then use Fuzzywuzzy for fuzzy matching. Finally, an example code was used to demonstrate how to use these two libraries for phonetic matching.
