Data visualization - Bibliography? (※5MB GIF included!!)

Data visualization of papers & keywords 

• Developed as a part of convergence research contest.
• Our team members decided to propose the concept for analyzing, visualizing and exhibit the research relationships in our institute.
• We started from extracting the keywords in papers published in recent 5 years from our institute.
• Because of the lack of time, I "conceptually" developed an application to show how the relationships can be visualized.

Data visualization, 2D or 3D? 

• The D3.js is now getting popular for most type of data visualization in 2D.
• 2D data visualization has advantages on concise expression and easy perception to users.
• On the other hand, the 3D visualization is needed when we want to provide "spatial" sort of experience to user.
• Usually the type of data we focused tends to be visualized in 2D, but we(actually I,) tried to visualize it in 3D for future.
• For instance, LBS or AR use.
• Of course the effective visualization approach should be discussed more in later.

Development of a demo application

• Like always, Unity3D is very useful when you need to develop an application in very short time. 
• The concept of my visualization is a planetarium, which each keyword is floating on the dome shaped sky. 
• Application includes relationship visualization functions and search functions. 
• Also the titles, authors and research fields can be seen if user selected certain keyword to get into the "Focus Mode". 
• Textures are simply made from MS PowerPoint. 
• Source database exists in Dropbox and read through WWW class at first time, but I changed it into TextAsset resource since the data is not going to be dynamically changing. 
• Again, the multi-channel visualization can be easily done though the multi-channel module I have.

Discussion? 

• As I mentioned, the effectivess of visualization should be improved in so many ways.
• Location based service application using GPS data can be easily developed, but the performance should be improved when using it with smart device.
• There's not much "analysis" of the data in demo application. Data analysis method in bibliography fields should be applied.
