Data Comparison Tool

This tool provides a comprehensive way to compare two sets of data, evaluating both exact and semantic equality of their values. It leverages text normalization and a language model to determine if the data originates from the same entity.

Features

• Text Normalization: Converts text to lowercase, removes punctuation, and normalizes whitespace.
• Value Comparison: Compares values directly and semantically (ignoring order for lists).
• JSON Traversal: Iterates through each key in the JSON objects and compares corresponding values.
• Language Model Integration: Uses a generative language model to assess semantic similarity and provide a final judgment on whether the data comes from the same entity.

Installation

To use this tool, ensure you have the necessary dependencies installed. You can install them using pip:

pip install genai

Usage

Functions

1. normalize_text(text):

   • Normalizes the input text by converting it to lowercase, removing punctuation, and normalizing whitespace.

2. compare_values(val1, val2):

   • Compares two values both exactly and semantically.
   • If the values are lists, it ignores the order of elements for semantic comparison.

3. compare_json(json1, json2):

   • Compares two JSON objects key by key.
   • Uses compare_values to evaluate each key's values.
   • Integrates a language model to assess semantic similarity and provides a final judgment.

Example

import json
import genai
import re

# Define your JSON objects
json1 = {
    "name": "John Doe",
    "address": "123 Main St, Anytown, USA",
    "hobbies": ["reading", "hiking", "coding"]
}

json2 = {
    "name": "john doe",
    "address": "123 Main Street, Anytown, USA",
    "hobbies": ["coding", "hiking", "reading"]
}

# Compare the JSON objects
comparison_results = compare_json(json1, json2)

# Generate final matching result
model1 = genai.GenerativeModel("gemini-2.0-flash-thinking-exp")
result_matching = model1.generate_content("综合这些信息，你认为可以判断两个数据来自同一主体吗？"+json.dumps(comparison_results, ensure_ascii=False, indent=4))
print(result_matching.text)
