从文本文件中创建带有实体注释的json文件，并将startIndex和endIndex附加到字典中

import json

def create_json_with_entity_annotations(text_file, json_file):
    # 读取文本文件内容
    with open(text_file, 'r') as file:
        text = file.read()

    # 解析实体注释，这里假设实体注释使用方括号括起来，如 [实体]
    annotations = []
    start_index = 0
    while True:
        start = text.find('[', start_index)
        if start == -1:
            break
        end = text.find(']', start)
        if end == -1:
            break
        entity = text[start+1:end]
        annotations.append((entity, start, end))
        start_index = end + 1

    # 创建字典并添加实体注释
    entity_dict = {}
    for entity, start, end in annotations:
        entity_dict[entity] = {
            'annotation': '实体注释',
            'startIndex': start,
            'endIndex': end
        }

    # 将字典转换为 JSON，并写入文件
    with open(json_file, 'w') as file:
        json.dump(entity_dict, file, ensure_ascii=False, indent=4)

# 示例用法
create_json_with_entity_annotations('input.txt', 'output.json')
