LANGUAGE FORUM

Problem Statement:

Being a part of computer science we often face problems of learning languages and have certain doubts on various concepts. We often refer huge books and attend different forums to get the doubts answered. We aim at having a system which could help one learn languages through Q&A with questions on languages and further bifurcated on topics. This would help the student and other people to get their answers at one place within a very short span of time.

Idea

Problem Statement and Scope
The existing systems on forums do have answers related to various languages and aspect; but they are not covered under one roof and might be sometimes feel irrelevant
Most of the industry today is dominated by IT. And many people emerge each year to appear for interviews in various companies; also students appear for exams. Such a system with integrated features on various languages and additional options would be quite helpful to the IT developers community
By having such a system users can have their work cut out on searching for relevant data to their problems. Also the bifurcated data to various domains will make the search towards the relevant things easier
The system also aims at answering the problems of various users by having professionals answering certain questions and also helps the users rate answers(in case of open ended questions)
At the application level the system also aims at having certain examinations at different levels
By having different sets of Q&A we can have people learning through these questions
By automating the process of collecting data we could have many questions on the languages helping learn in a more quantitative way
Open-ended questions may have multiple answers we can have ratings for the answers to let the user decide the best answer for himself
By having a whole bunch of Q&A it will enable users to get the questions having at one place. Making the learning easier for the users.

Novelty of Idea

The system is aimed to be developed as an web application

Relevance and Applications

The problem domain is relevant to the IT industry and the IT in terms of education
So its applicable to students, professionals and also at a enterprise level because the system also aims at having certain online examinations which would help test the knowledge of various users at various levels

Solution

Technology Layer/Solution

Technology – Java

Platform – Windows, Google App Engine

Architecture of the Solution – Multi-tenant

Proof of Concept

An application named “Online Book Purchase” was being developed by us before which was a web application and holds certain features which would be helpful for the development of the application

R&D

R&D Elements in the solution

We have checked out on various forums on the computer field
Checked out the peculiarities of different web applications on the same
Looked towards various different aspects at betterment
Aim at providing an online examination with time-boxing feature to enhance the product. Pretty much like various different online examinations do

Improvements on existing solution/Provides a new solution

We aim at having a different and simplified view at providing the service to the user by managing the data for them and providing the better of those
If implemented as a web service it would help enterprise and education centers on filtering the interview procedure and examinations by having the candidates passed to appear for the interview and at the education level at having students have different reportings of their performances
It would be an application for all the different stakeholders in the IT industry

Comment by Ankit Marothi on April 3, 2011 at 8:29pm: Hi Sir,

I had given a few more tries with the saxparser but since the HTML is not well formed I cant get the data filtered.

Here's a code that i used for balancing the tags it has got to do with HTMLparser but i just am using it to balance the tags.

I cant figure out how to save the changes to the file again. I have commented the lines of codes i added. Can you please help out.

Comment by Ankit Marothi on March 25, 2011 at 8:30pm: Sir, I got it soughted. Proceeding on the same.:-)

Comment by Ankit Marothi on March 25, 2011 at 7:02pm: This is the fragment where I'm facing the problem...

messages.add("start " + element.rawname);

super.startElement(element, attributes, augs);
}

}

public void endElement(QName element, Augmentations augs) throws XNIException {
messages.add("end " + element.rawname);

super.endElement(element, augs);

Comment by Ankit Marothi on March 25, 2011 at 7:00pm: Sir, I'm working on the html balancing stuff and am stuck on adding a string element to the type List.
Here's the code.
I'm also sending the code as a zip to you.
