Part 2: How the Google Predicition API Can Help a Business ratings and Reviews Service Like Wasamundi.com
There has been lots of buzz about the cloud in recent years and you may have heard of popular cloud related acronyms like IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS (Software as a Service). If you have never heard of them, close this page, go to Youtube and watch Gangnam Style for this was not written with you in mind. Now back to the cloud talk. Today I invent a new acronym, MLaaS (Machine Learning as a Service) - at least I think I have invented the acronym.
If you know what machine learning is, skip to "How the Google Predicition API Can Help a Jobs Website"
Machine Learning is ... well you guessed it, "Machine Learning". Its all about teaching machines to make predictions, decisions or recommendations based on historical data (your computer science teacher may not describe it like that, but then he did not write this post).
Now put one and two together and you get Machine Learning as a Service which is a cloud service that provides apps or humans with machine learning services via a pay-as-you-use model. Freeing them of the burden of having to build machine learning software themselves, buying a machine to run it or both.
The Googe Prediction API is an example of a machine learning cloud service.
How the Google Predicition API Can Help a Jobs Website.
The Google Predicition API a machine learning service which in Google words gives you the ability to "Use Google’s machine learning algorithms to analyze data and predict future outcomes using a familiar RESTful interface."
This can be used by a jobs website like Njorku in the following ways:
- Automatically categorize user submitted CVs. For example a user should submit her/his CV and it will be categorized as Marketing, Software Engineering, or Legal to name a few so that only jobs relevant to that category are emailed to the user. The reverse can also be done where by jobs crawled from other websites are automatically categorized using machine learning and emailed only to users interested in that category
- Do a "Users who viewed/liked this job also viewed/liked the following jobs" section. Where by a user viewing a banking job gets recommended other jobs based on what previous viewers of that job liked/viewed.
Many more ideas come to mind but I planned to write this in an hour and for you to read this post in five minutes but I fear I am already failing at one if not both.
So How Will This Work ?
For the first use case, people will have to build the training data for the model. This can be a CSV file that looks like this:
"marketting", "text found in one user submitted marketing CV" "software engineering", "text found in user submitted software engineering CV" "marketting", "text found in another user submitted marketing CV" "legal", "text found in a lawyers CV"
To build a good model, you will need hundreds of CVs per category but a usable model can be created with at least tens of CVs per a category.
This is a basic idea with the least implementation information required to push it through. Taking it to production will need some more development. You can start by reading the Google Prediction API documentation.
Next week I will write on how a real estate service like WasaHostel or a local business directory like WasaMundi can use the Google Prediction API to their advantage.
You can recommend any start-ups you will like me to "make smarter". :-)
