The Blue Nile

"The Blue Nile" is an ontology visualization web app that can visualize graph network ontologies in 3D/VR/AR/2D format.

In this project, I made a web app that visualizes a NASA dataset in 3D and AR using https://github.com/vasturiano/react-force-graph

I made the front end in next js and I managed to change the XML file:(http://webarchive.loc.gov/all/20111207225100/http:/nasataxonomy.jpl.nasa.gov/xml/subjects.skos) into JSON

using this script: https://bl.ocks.org/mbostock/1080941

Then I extracted useful information that helped me make this graph and put it in a "data.json" file.

the JSON dataset syntax is as follows:

{

"nodes":[

{

description: .....,

id: .....,

group: parent of current node. used to color the nodes,

tagName: used to identify type of node: label, concept or note

},

"link":[

source: id of source,

target: id of target

]

}

Benefits of the web app:

• It can serve as an API endpoint, or a library that can help developers in NASA gamify the process of model classification and metadata collection
• It can help teams collaborate in real-time VR environments. With Vr headsets, team members will be able to change and interact with the nodes together. They can also be able to create new ones.
• Help in visualizing queried data. With more work on the data, I believe that the entire NASA dataset can be queried and represented in this way
• Help Develop better ways to extract nodes and links from the well-known ontology formats using AI and natural language processing to predict relationships

This has been a tremendous learning experience for me. I learned a lot of new things I never knew before. At first, when I chose this challenge I knew nothing about data science, I was overwhelmed. I could understand any of the concepts. But then I remembered a quote by Warren Buffet: "We don't have to be smarter than the rest. We have to be more disciplined". So then I made it my motto and I kept reading everything I could find, I even started reading the book "The rise of the knowledge Graph". The dots slowly started connecting, and even though I have a really really long way to go I know that I am better than I was yesterday.

Doing it alone was not an easy task, however, it gave me the chance to really challenge myself.

Before this challenge, I wanted to be a computer science/software engineering student. But now after going through this challenge and learning so much I will definitely consider data science/machine learning.

I really learned a lot!!

I don't wish I had more time to work on my challenge since the experience and the knowledge that I got in this short amount of time far outweigh anything else. Besides, I will be working on "The Blue Nile"(The name of the App) in my free time, I'm already invested in it. I claimed a domain from godaddy.

Thanks, NASA for this awesome challenge!!!
