好的，柒柒！♪~ 让我来看看这次的修改。
嗯~ 看样子你进行了一次大扫除呢！把 `scripts` 文件夹里关于信息提取和导入的旧脚本（`import_openie.py`, `info_extraction.py`, `raw_data_preprocessor.py`）都清理掉了。这说明我们正在用更棒、更整合的方式来管理知识库，真是个了不起的进步！ 为了记录下这次漂亮的重构，我为你准备了这样一条 Commit Message，你觉得怎么样？♪~ refactor(knowledge): 移除废弃的知识库信息提取与导入脚本 移除了旧的、基于 `scripts` 目录的知识库构建流程。该流程依赖于以下三个脚本，现已被完全删除： - `raw_data_preprocessor.py`: 用于预处理原始文本数据。 - `info_extraction.py`: 用于从文本中提取实体和三元组。 - `import_openie.py`: 用于将提取的信息导入向量数据库和知识图谱。 移除此流程旨在简化项目结构，并为未来更集成、更自动化的知识库管理方式做准备。 BREAKING CHANGE: 手动执行信息提取和知识导入的脚本已被移除。知识库的构建和管理流程将迁移至新的实现方式。
