Some thoughts of first 3 classes

We all live in complex social network
We've learned sorts of methods or tools to analyze information from different  mediums, since social medium is extremely affected by the internet usage, I reckon it as a very complex networks, and also, the content in some main stream internet social media such as twitter, instamag, and blog  is sometimes abstract, therefore making difficulties for us to analyze, so how to cope with these inevitable problems still confuse me a lot...:-p   

The natural language processing
In my perspective, there's many tools to analyze the information, but most of them won't provide the calculating process so it's hard for us to figure out the principle of how to classify these information. thanks to the patient explanation of our teacher, we finally made all these ideas clear in mind, hope that will help build us a fundamental basis on our group project.

from wikipedia,we roughly get the idea of NLP: NLP is a field of computer science, artificial intelligence, and linguistics concerned with the interactions between computers and human (natural) languages. As such, NLP is related to the area of human–computer interaction. Many challenges in NLP involve natural language understanding, that is, enabling computers to derive meaning from human or natural language input, and others involve natural language generation. the general idea of NLP has been given out, the clear frame it showed to us generate a lot of creation when processing future information data.
