Data extend to Social data that I will discuss today. You have to understand the social network analysis. So, you will know how people connected by use social data. Before you have a social data, you must Internet connection to connect the data. You also have the information overload in the Internet (Big data). You will query from the big data. Nowadays, the role is change, many people tag data from themselves. So, Why we tag?? I will talk about this. First, you must understand the following...

> Social book marking: It is a center online service that helps people to add, comment, edit, and share bookmark of web document that they like.

>Metadata/Tag: It will describe the information or detail of data such as when it build, where, how or the method.

Social tagging challenges

All the keyword below, you have to concern about that. You can tagging something and put some keyword on it. When you go to some website, there will have categories that use you to put that information. User will not feel like they were monitoring. Social tagging makes different things. When generate the tag, they have many set of keyword. The keyword that you search will keep in your computer. Even through when you search for that keyword again, it will show that keyword. The purpose for design of tagging system is to response ans carry the demand of user. There are advantage and disadvantage for suggest the tagging.

Disadvantage
- Hind user preference
- I pick a suggest tag that now I cannot remember.
- I tend to overuse same tags all over again “exploit” vs. “explore”. It means that you over use the keyword that you search.

Advantage: when you do tagging, you create the cool start.
- Less effort and also save your cognitive
- Encourage user to use tag. It means that you get cool start.
- Agreement in vocabulary
