IR Homework1 Introduction

This is the homeworks of NTUST CSIE IR course in 2017.

steps:

1 : get the query list
2 : get the dictionary and document tf,idf and query tf
3 : document term weight，先取得一個 document 作爲豎着向量。再找到 query term weight，作爲橫着向量
4 : compute the 兩個向量點乘
5 : compute the 兩個向量長度
6 : 計算 cos
7 : 排序比較對於這個 query ，最接近的結果 cosVal 越大
8 : 找到所有的 query 的排序結果
