Getting Started with MEAN.io Stack in less than 60 seconds

I had the pleasure to play around with the MEAN.io stack and it feels really easy to get started. I had mean.io up and running within 60 seconds, and i’m sure you can do it too.

For those who have no idea what the MEAN stack is, it is akin to the LAMP stack, but MEAN is built upon:

  1. MongoDB
  2. Express.js ( a framework built on top of Node.js )
  3. Angular.js – Super heroic JavaScript Framework by Google
  4. Node.js

And guess what ? The friendly folks at mean.io have create a repository that recreates the mean.io stack

Here’s how you can get started with MEAN stack in less than 60 seconds:

  1. Go to http://www.mean.io/ and click on the large green “Download” button.
  2. Unzip the folder downloaded from step 1.
  3. Change directory into the root of the folder.
  4. If you have not installed bower, you can install it using the following command:
    npm install -g bower
  5. Enter this command from your terminal:
    npm install
  6. Once everything is installed, you can start the server using:
    grunt
  7. If you noticed that the grunt command is not found, than chances are you have not installed grunt. You can install it using this command:
    npm install -g grunt
  8. Now visit: http://localhost:3000
  9. You are done!

If you happen to see that there are no CSS related stuff loaded, than chances are the /lib folder are not found in the project. If this is the case, you need to run

sudo bower install --allow-root

first. Than, you need to run

 npm install

again to make sure everything is loaded perfectly.

Now you have completed installation for mean.io.

Smart Assisted Query for ECommerce Search

Screen Shot 2014-01-10 at 4.59.32 PM

The main idea is to enhance user experience by reducing the number of clicks required for a user to reach her desired product page after a user performs a query.

The problems I am trying to solve are:

  1. Optimize both click through rate and query click through rate after a user performs search
  2. Allow user to quickly reach product page with minimal clicks.

The solution i’ve implemented is to allow user to perform “drill down” during the query phase. Instead of just showing autocomplete suggestions, I show possible categories/attributes based on the keyword ( or product ) the user is searching for. The user can than select categories/attributes directly while performing search.

Feel free to view the demo (interface is in Mandarin Chinese) here:

This is the desktop version: note that as the query selects a brand name from the autocomplete suggested terms, the query suggestion switches to provide category/attribute selection.

 

Mobile version. This is a proof of concept done using powerpoint and some prototyping templates.

Social Behavior of Investors

Screen Shot 2014-01-10 at 4.44.23 PM

“Social Behavior of Investors” is my master’s thesis completed just a few months ago.

The problem I am trying to solve here is to matchmake investors with companies ( especially early stage startups ) in order to get the investment funds flowing. I did not focus on public companies as the data are generally public; a great amount of research has been done about them already. But what about the smaller companies where little financial information about them are available ?

The solution is to make model this problem as a classic link prediction problem: given a social network of investors and companies in Time A, predict if (which) new links ( investments ) will form between investors and companies in Time B. I’ve used dataset from Crunchbase for the purposes of this research.

The result is encouraging: the accuracy rate is up to 90% with AUC ( area under curve ) of up to 87% for both datasets[1] that I have used.

A video demo:

[1] I derived 2 datasets from Crunchbase: using Facebook as a seednode, i collected companies, financial organizations and individuals 4 hops away from Facebook. The second dataset is based off RenRen, and collected companies, financial organizations and individuals 4 hops away from RenRen.

GoSpread.me

Screen Shot 2014-01-10 at 5.05.45 PM

GoSpread.me was a weekend hack project when i was trying to help my friend market his Facebook fanpage and his website.

The problem: faced with limited budget and marketing options, it appears that spreading the word about his FanPage and website through his friends is the best way to get Likes and quality visits to his site since his friends all know him. However, there is no easy way to reach all his friends on Facebook; making wall posts/public posts don’t really help due to EdgeRank.

The solution: I’ve built a tool that allows my friend to send personalized messages to all of his Facebook friends in an automated manner. Think of it as “Autoresponder Meets Facebook Messaging”

QueryBox – an update.

Screen Shot 2014-01-08 at 3.19.20 PM

The main idea of Querybox is to allow non-technical users to quickly slice and dice through social data.

The problem I am trying to solve is avoiding the use of dashboards: i want users to immediately get to the dataset/point they are looking at. In a way, dashboards can be confusing and may or may not surface the exact data users want.

The solution we proposed is to use a smart assisted query that allow non-technical users know the type of queries they can conduct based on the dataset they have. Using the assisted query UI, users can conduct queries without the need to know programming.

Feel free to check out Querybox and view our winning presentation during StartUp Weekend 2013 here.

Open Data Meets Yahoo Query Language

The main idea is to help developers ( or even semi developers ) to quickly query Taiwan’s Open Data. However, since the Taiwanese government do not have a stable platform for hosting its dataset, we suggested hosting the data through Yahoo Query Language (YQL) platform with support from Yahoo Taiwan.

Taiwan’s government data is ported and made YQL ready. I’ve built a smart assisted query interface that allows non-technical people write YQL queries to extract government data. [ Video in Mandarin Chinese. ]
