Description: 1-The Cranfield collection is a standard IR text collection(included in this directory)., consisting of 1400 documents the aerodynamics field.Write a program that preprocesses the collection.Determine the frequency of occurence for all the words in this collection. Integrate the Porter stemmer and a stopword eliminator into your code.
2- For weighting, use the TF/IDF weighting scheme.For each of the ten queries provided on the class webpage, determine a ranked list of documents, in descending order of their similarity with the query.
3- I will have to implement an efficient and effective spam filter (a text Classifier).

Description: 算法思想：提取文档的TF/IDF权重，然后用余弦定理计算两个多维向量的距离来计算两篇文档的相似度，用标准的k-means算法就可以实现文本聚类。源码为java实现(Algorithm idea: extract the TF/IDF weight of the document, then calculate the distance between two multidimensional vectors by cosine theorem, calculate the similarity of the two documents, and achieve the text clustering with the standard k-means algorithm. Source code for Java implementation)
