垂直搜索引擎数据采集技术的研究与实现的中期报告
摘要：
本文是一篇关于垂直搜索引擎数据采集技术的研究与实现的中期报告。本研究旨在分析目前主流搜索引擎无法满足特定领域的搜索需求，并提出了一种基于垂直领域的搜索引擎的构想。该搜索引擎需要收集特定领域的数据，并且根据用户的搜索需求提供高质量的搜索结果。本文介绍了目前主流的搜索引擎的特点和优缺点，并提出了垂直搜索引擎的构想。接着，本文重点介绍了数据采集的基本原理和技术，并依次介绍了数据采集的流程，包括数据源的选择、网页抓取、数据清洗和数据存储等方面。最后，本文结合实例介绍了如何基于Python语言实现数据采集的各个环节，并给出了数据采集的结果和分析。
