Information-Retrieval

NKU 信息检索; NKU Information Retrieval

1. 布尔检索：给定文档集合，使⽤BSBI算法实现倒排索引的构建，并使⽤可变长编码压缩保存到磁盘，然后实现联合查询。最后额外选择实现⼀种编码⽅式（gamma或者delta编码）
2. 阅读论文，并汇报。
3. 向量空间模型：给定查询文档集合（诗词txt文件），完成向量空间模型并对文档集合实现查询功能。
4. 功能设计（开放型任务）
5. 大作业：实现web搜索引擎。

This repository is for the Information Retrieval course at Nankai University, and the assignments are as follows:

1. Boolean Retrieval: Given a document collection, implement the construction of an inverted index using the BSBI algorithm, compress it using variable-length encoding, and store it on disk. Then, implement Boolean queries. Additionally, choose to implement one encoding method (gamma or delta encoding).
2. Literature Review and Reporting.
3. Vector Space Model: Given a query and document collection (text files of poems), complete the vector space model and implement query functionality for the document collection.
4. Functional Design (Open-ended task).
5. Major Assignment: Implement a web search engine.
