sensitive-word: sensitive word filtering tool, efficient DFA algorithm implementation

General Introduction

Sensitive word filtering tool (Sensitive Word) is a high-performance Java sensitive word filtering tool based on the implementation of the DFA algorithm framework. The tool can efficiently detect and filter sensitive words , support for multiple format conversion and custom replacement strategies. Its design goal is to provide an easy to use and superior performance of the sensitive word filtering solution for a variety of application scenarios .

Function List

• Sensitive word detection: support sensitive word judgment, return, desensitization and other operations
• Format Conversion: Support full- and half-corner conversion, traditional and simplified Chinese conversion, English case conversion, etc.
• Customized Replacement: Support user-defined sensitive words and replacement strategies
• Dynamic update: Support the dynamic update of the sensitive words database, real-time effective
• Tag interface: support for tag management of sensitive words
• Special Character Handling: Supports flexible matching by skipping special characters

Using Help

Installation process

1. Preparing the environment: Ensure that JDK 1.8+ and Maven 3.x+ are installed.
2. Introducing dependencies: In the project'spom.xmlfile to add the following dependencies:

   <dependency>
       <groupId>com.github.houbb</groupId>
       <artifactId>sensitive-word</artifactId>
       <version>0.19.2</version>
   </dependency>
   

3. initialization: Initialize the SensitiveWordHelper class in the project.

Usage

1. Sensitive word detection::

   String text = "待检测的文本内容";
   boolean contains = SensitiveWordHelper.contains(text);
   

   This method returns a boolean value indicating whether the text contains sensitive words.

2. sensitive word replacement::

   String replacedText = SensitiveWordHelper.replace(text, '*');
   

   This method replaces sensitive words in the text with the specified characters.

3. Get all sensitive words::

   List<String> sensitiveWords = SensitiveWordHelper.findAll(text);
   

   This method returns a list of all sensitive words in the text.

4. Customized Sensitive Phrase Bank::

   SensitiveWordHelper.addSensitiveWord("自定义敏感词");
   

   This method allows users to dynamically add sensitive words.

Detailed Operation Procedure

1. Initialize Sensitive Word Database: Load the default sensitive lexicon or a customized sensitive lexicon at project startup.
2. text detection: In the text content that needs to be detected call theSensitiveWordHelper.containsmethod to determine if it contains sensitive words.
3. sensitive word processing: Choose to use, based on business needs, thereplacemethod for sensitive word substitution, or use thefindAllmethod to get all the sensitive words for further processing.
4. dynamic update (Internet): During operation, theaddSensitiveWordThe method dynamically updates the sensitive word database to ensure real-time and accurate detection of sensitive words.
