Web Technologies Project on Car Pooling Application

A brief walkthrough of the Car Pooling project

This Car Pooling application allows users to:

  • Become a member of the carpooling community (register and login)
  • Join rides
  • Offer rides
  • See the most popular rides taken

Joining A ride

The user searches for:

  • Source (starting point)
  • Destination (drop off point)

On selecting a ride, choose the number of seats (based on availability)

The cost of the ride will be displayed and will ask for verification of booking the ride

Offering the ride

A registered user creates a ride by

  • Selecting the starting point (source)
  • Selecting the endpoint (destination)
  • Entering car model (registration)
  • Enter the number of seats available
  • Cost per kilometer
  • The offered pickup points

 Inclusion of features

  • Webservices using RESTful APIs
  • Ajax Patterns
  • Submission throttling
  • To populate the source and destination of the list being searched
  • Multistage download
  • On loading the home page, the images are downloaded one after the other
  • Comet
  • SSE (server-sent events)
  • To view the topmost rides driven/ joined

Use of framework

  • RESTful API’s
  • Flask micro framework
  • Bootstrap for CSS
  • Mongo DB (for the database)

Intelligent Component

  • Calculate the fare: – ((distance * cost/km) / seats), Distance is calculated using the haversine algorithm
  • haversine algorithm – Takes two points (their latitude and longitude) and used to calculate the distance
  • To select pickup points – K nearest neighbors used
  • The intelligent component is trained using the dataset having rows as Place name, latitude, longitude
  • The model generated is used to predict the nearest neighbors of any given place
  • To decrease calculation time a pre-computed matrix of given places with respect to  distance  from all other points (places) is used

Two such matrices are used:

  • Distance matrix
  • Indexes matrix

Design & Development of Educational Institutions Grievances Portal Project

Currently, there is a portal name Grievances portal similar to this. In the grievances, portal people can share their local problems and their solutions are provided by anyone. But in our portal people can share problems of any region and they are taken up by colleges of the region facing problems. This helps several institutes to work collaboratively on a large scale.

Introduction: 

This Educational Institutions Grievances Portal Project report gives a scope description and overview of everything included in the Project Report.

The following is the overview:

Purpose:

The purpose of this report is to give a detailed description of finding and solving common issues with educational institutions. It will illustrate the complete declaration and purpose for the development of the system. It will illustrate an interaction, constraints, and interface between different users of the system.

System Overview:

This Grievances Portal Project takes the problems faced by students of a particular institute as input in the form of upvotes or posting a problem. All users have to log in using Google authentication facebook or any social media platform. This helps to keep the track of users participating.

The institute first has to register so that it is possible to keep a track of which colleges are participating. All the passwords of institutes are encoded using ​md5 ​and the colleges can then take up the problems about a particular locality and can do collaborative projects to solve them.

The solutions are generally provided in the form of videos which is easily understandable to the local public. But before posting solutions, the colleges have to first check for the authenticity of the problems. They can mark any solution as duplicate or bogus.

This ensures any unrelevant problems from reaching admin and the system is thus maintained. Finally, a report is generated in the form of an excel sheet that helps the admin to know the problems existing in our country. This file can be downloaded as well.

Model of Solution:

Goals:

The Grievances Portal Project aims for semantic text/web page classifications. It provides a better and more comprehensible platform for posting college-level problems and finding solutions. It is extremely user-friendly and easy to use.

Objective / Future scope:

● Define a mechanism to decide ​the count of votes needed to approve an issue
● Once voting is closed for an issue i.e. when the issue is upvoted by the number of users count of votes needed to approve an issue, then the upvote facility will be closed and the system immediately sends a notification to all the related institutes.
● There should be a way to maintain “Reputed Institutes”
● Admin should be able to see which Institutes are working on that problem.
● Each problem should have a thread on which registered users may discuss its solution or upvote or downvote the solutions also.
● The emails of users sending “bogus approved issues” may be blocked when marked as bogus as colleges​

Functional and non-functional requirements:

Grievances Portal Project website there three types of users:

● Citizens
● Institute
● Admin

All users get the same view of the website with similar functionalities but they all perform different tasks.

Functional Requirements:

User Functions

1. Sign Up
2. Can change his/her profile
3. To add an issue
4. Users may also look for issues in any region
5. Can visit a problem description directly through a URL and upvote for it.
6. Users cannot upvote the same issue more than once.
7. Will be notified through email to approve if any solution is available for any of the problems he has upvoted for.

Institute Functions

1. Institutes will have a login

2. After login they will be able to see the issues of ​their region only​ like

a. Unsolved issues (approved)
b. Issues with solutions

System Functions

1. Knows list of Institutes per district
2. Gets added issues and stores
3. Keeps a track of upvotes per issue – Once upvotes reach a ​threshold ​the issue is notified to all the Institutes in that region or district via email. (Institutes can see approved issues of their region via their login as well).

  • Problems of a district may be shown to that region instead of that district
  • Institutes of nearby districts may fall under the same region.
  • Or simply it can be forwarded to the Institutes falling in the same district.

4. Once an Institute submits a solution, the system notifies all the users who upvoted for that issue. So that they may approve the solution.

5. Will know how many solutions an Institute has provided. It means how many of them are solved issues.
6. Long pending issues should be notified to UGC who then will notify the Institutes
7. Institute should be notified when its solution is approved.

Administrator Function

Reports to be generated

The technology stack used:

Backend: PHP.
Frontend: Html, Jquery, javascript, Ajax, bootstrap.

Implementation strategy:

1. Initially, the whole template was designed to suit our requirements.
2. Bootstrap was used for the development of the template of this website (SB Admin 2)
3. All pages were then linked which made the division of work easier.
4. The whole backend was made using PHP.
5. There were various event listeners used in this system like on focus, click, change, etc., which were implemented using JS and Jquery.
6. Almost all pages had the same page refresh and reload for which we have used AJAX.

Conclusion:

1. Our team has completed a Web Application
2. Product Design was a crucial point in the development
3. We now have a complete understanding of how a website works from start to end
4. We learned a new language – AJAX. We also strengthened our knowledge in PHP, JS, and Jquery.
5. Most importantly, we learned how to work in a team.
6. The future scope of our specified in the Goals -> Objectives section.

Online College Complaints Suggestions and Compliances PHP Project

“Online Complaints, Suggestions, and Compliances” is a website and through this project, we have learned to design webpages using HTML, CSS, JavaScript, and PHP. It has enabled us to have a deeper understanding of how frameworks help in the development of websites.

Thus, in this College Complaints Suggestions and Compliances project, we have acquired a lot of knowledge about various technologies in web development. We have explored many new concepts on the web, such as JavaScript and AJAX.

Solving these problems must be quick and transparent. Often, Students shy away from writing complaints and suggestions into the box, as students are afraid of peer views of their actions.

Problem Statement:

A College Complaints Suggestions and Compliances Web Application to allow students to raise complaints and suggestions transparently without exposing their identity.

The Objectives of this application are:

  • Allows students to log in with E-mail verification before submission of complaints and suggestions
  • Allows students to track their submissions from their portal
  • Allows teachers to reply and change the status of the submissions without exposing student’s USN
  • Provides a pie chart representing the types of submissions
  • Admin can block submissions using foul languages

Steps Involved:

Step 1: The web application loads the home page. With options of Student, Teacher, and Admin
Step 2: On selecting Student, the user must first log in using the login page. On successful login, the user is greeted with the student portal.
Step 3: The student portal allows users to check the status of the previous complaints, and suggestions.
Step 4: Students can click to submit complaints and suggestions, after the verification page using email verification.
Step 5: The student can click on the logout option and is then taken to the login page, which has the option to return to the home page
Step 6: On clicking the teacher option on the home page, the teacher has to log in. They are then taken to the teacher’s home page. The teacher can choose to view complaints and suggestions.
Step 7: On clicking on a complaint/suggestion is taken to the auction page. Where the teacher can change the status of the complaint with the option to reply.
Step 8: After replying, the teacher is taken back to the teacher’s home portal. On logging out, you are taken to the login page, with the option to be redirected to the home page
Step 9: On clicking the Admin option on the home page, the admin has to log in. They are then taken to the Admin home page. Admin can choose to view complaints and suggestions which are blocked due to the use of foul language. After allowing or disallowing the admin is returned to the Admin home portal. On logging out, you are taken to the login page, with the option to be redirected to the home page.

Functionalities

Login: This module allows students, teachers, and Admin to log in with different access to web pages and controls. The username and hash of the password are compared with the Tables stored in the Database.

Signup: This module allows students, teacher, and Admin to register their access to the web application. By signing up the user is registered in the Database, so that their login credential is saved for future logins.

Complaint and Suggestion Form: This module allows students to fill up complaints or suggestions. Before uploading to Database. It checks for any foul language violation. It marks the entry to be checked by the admin, before allowing it to be viewed by the teacher.

Student Submission view: This module allows students to view the status and reply to their complaints or suggestions previously raised. On clicking the user can re-open a submission.

Verification: Students have to enter the One-time password (OTP) sent to their email to verify the authenticity of the complaint and suggestions. This module is implemented using PHPMailer Library.

Teacher submission view: This module allows concerned teachers to view the complaints and suggestions without revealing students’ USN. On selecting a submission, the teacher can update the status, reply to the same, and notify the same to the student’s email.

Admin unblock submission: Display submissions flagged due to misuse of the platform. Allows admin to unblock the submission if it is appropriate, and updates the same in Database.

Application

  • This application can be used in all colleges to collect Complaints and suggestions
  • It can be viewed by a teacher without relieving student’s use
  • Students get updated by their emails when the status of their submissions changes
  • The teacher can view a pie chart representing the type of submission. So, they can concentrate on a given area
  • Submissions using foul language are blocked and are reviewed by Admin

Conclusion

The internet is a very powerful platform for people to share their views in confidence. This Web Technology Mini Project draws further on the notion of the same lines, allowing Students to place complaints and suggestions without relieving their identity. Colleges and institutions improve from the useful insights provided through our platform. Thus, allowing them to understand the needs of students wholesomely.

Snippet Visualization System PHP Project Code Report PPT

this web-based Snippet Visualization System is to provide a visualization-based technique for web search results based on textual snippets. This project was developed with PHP, javascript, Ajax, and MySQL Database. Here Students can download the complete project code, and report PPT.

Introduction

Many internet users search for some query and as a result, they get a ranked list of URLs.
The user could get disappointed with this related search.
Hence, we are developing a system that is focusing on retrieving search results in thumbnail form.
Users can interact with more results in a single view.
It affords easy navigation and is straightforward to interpret with the user.

Objectives:

To perform pre-processing of collected data.
To perform similarity identification and ranking of the snippets using the k means algorithm.
To perform optimization of the snippets for visualization purposes.
To analyze the performance of the proposed system via experimental evaluation of results.

System Architecture

System Architecture

Modules

1. Collecting information:

It is the first step where the system will collect data from a custom search engine and store it in a database for further processing. Data is stored in the form of text, URLs, and descriptions displayed on each web page.

2. Pre-processing:

It is the second step where each entry returned from a textual query is processed and its term frequency vector extracted. 

3. Similarity Identification:

Multidimensional projection techniques may be employed to generate visualizations that favor the perception of groups of similar documents. Such methods typically represent documents as points in a two-dimensional visual space, where neighboring points correspond to documents with similar content. However, points only convey information on neighborhood relations.

4. Ranking:

Snippets collected in similarity are then ranked in this module using the following algorithm.
• Text-based ranking algorithm.
• Weighted page ranking algorithm.

5 . Optimization:

This module Optimizes the placement of the snippets to avoid overlapping while preserving data neighborhoods as computed by the projection.

Implementation

For the implementation we have used different web technology ie., PHP, javascript, ajax, and open-source databases i.e., MySQL

Conclusion:

We introduced the Snippet visualization technique to visualize the collection of the textual result returned from the webpage.
The system collects URLs from webpages displayed as a result of a search query and stores them in the database.
After storing the data in the database it will display all collected text, URLs, and descriptions on the server side.
Then it starts preprocessing the collected URL. Hence it is useful to the system to do further task. Finally, preprocessed data as output is displayed.
