Week 3- web scraping

Here is what I have done on week 3

Gaoting Xu

In what ways does Bucher feel that algorithms are encouraging new ways of ordering the world? 1.系统大数据学习:In data-intensive environments such as social media, machine learning algorithms have become a standard way of learning to recognize patterns in the data.其中models是理解machine learning的最核心的一环 2.最common way的一种algorithms learn is supervised learning.

What are some connections between algorithms and power? 1.For an understanding of algorithmic power, this implies that algorithms do not have or possess power。 2.algorithms enact “the possibility of conduct and putting in order the possible outcome” 机器和算法是没有属性的,但是使用的人是有属性的。 对于数据的保护与记录也是应该有规则的。 在做web scraping的时候应当注意算法代码的各类空格填写,因为爬取的过程中可能会出现各种因为没有空格导致的爬取失败。同时,paython的算法爬取学习也是困难的,但是并非没有解决的办法。要学会看懂每一行代码的意思,比如说for 字段的内容循环,根据需要爬取的内容去动态调整自己的爬取办法。 从某种意义上来说,paython 和outwit hub是同一种类型的爬取内容和图片的办法。但是对于如何从关键词中提取必要的内容这一问题,仍有待日后继续研究和学习。
