Abstract
In this, the system will collect SMS’s and online Feedback from students in free text format. To get instance response of lecturer
feedback by analyzing free text messages using sentiment analysis. It is very low cost and plat form independent. It will show you
three different outputs, i.e. Good, Bad and Average/Neutral. The result will be shown in graphical format.
Key Words: Sentiment analysis, online feed-back.

1. INTRODUCTION
In this we introducing the feedback from student by
collecting through SMS’s and online using free text for
assessment of teaching. In traditional method, the
assessment of the teacher is done by students in the format
of Multiple Choice Question (MCQ) or polling using SMS
facility. In the MCQ, the feedback may be a single-alphabet
(A or B or C or D) and in the case of polling, either we can
select Yes (Y) or No (N) to give feedback about the teacher.
In the proposed system, the assessment of the teacher is
done by students in the form of free text. These SMS’s are
collected by the System. Then it will analyze the SMS’s and
gives the feed-back of teacher by using Sentiment Analysis.
The system will have lecturer and student login pages. In
student login, there is an option to give feedback with many
categories (teaching, behaviour, communication,
knowledge, interaction) of a teacher. The system will check
the spelling and grammar errors for the free text given by
the student and it will highlight the errors, for changing to
correct one. In Lecturer login, we will show the feedback in
graphical representation for all categories and overall
presentation also.
2. LITERATURE SURVEY
Zhang et al, proposed an important system application in
text mining. Sentiment detection is becoming more and
more important, due to the expanding volume of available
online information, such as micro-blogging messages and
review comments. As a result, a lot of sentiment detection
methods have been developed, among which machine
learning methods have received a lot of interest.
Michael Hagenau et al proposed a system in which it
examines stock price. Effects can be automatically predicted
by analyzing unstructured-textual information in financial
news. The main contribution is the usage of expressive
features to represent text feedback as part of our word
selection process. The methodology can be transferred to
any other application area providing textual information and
corresponding effective data.
Pete Rotella and Sunita Chulani has proposed a system in
which it conducts a Customer Satisfaction survey (CSAT)
each year to gauge customer sentiment regarding products,
technical support, technical services, order fulfilment, and a
number of other aspects of the company’s business using
free text. As a result, the company can make changes
according to the survey and user’s requirements.
Karma soft gave a detail description for SPELL-CHECK for
free text in ASP.NET. It is using Microsoft office word’s
spell- checking method. The text data will save in word
document and checks the spell. It will give you an option to
change the mistakes, if any.
Llia Smirnov gave the varieties of stemming algorithms.
Stemming is to change the words to its root word. For
example Teaching is changed to Teach.
Willett Peter gave briefly explained about Porter Stemming
Algorithm. He explained how the algorithm works before
and after. He tells about efficiency and it’s important also.
Steven Abney gave how to do a POS-Tagging and parsing
simultaneously. POS-Tagging is to find the parts of speech
for a sentence includes parsing. Parsing is used in Natural
language.
By using this SMS’s and online feedback, the assessment of
the teacher will be more faster and easy. This method will
be more useful in educational institutions for the teaching
evaluation. By using this, we can get the instant response
from the students. The students will also interestingly
participate in this survey. For this method, we need an
internet enable computer and mobile-phone.

3. PROPOSED SYSTEM
Feedback will be taken from 2 ways. First is through student
login. Second is through SMS. The database will maintain
the login detail of student and staff. The data that entered in
student login page will save in database along with SMSs
that are received for a particular teacher. We will merge
those data in a staff id. Then we will analyze the data with
sentiment analysis method for result. The result should be
shown in lecturer login in the form of chats for better
understanding purpose. The comments and messages that
are received for lecturer also shown in their login.
Fig -1: System Architecture
In this system, we have 10 modules. The introduction of
each module is given below.
Fig -2: Login Screen
Student Login: In this, Student can give feedback to many
categories (teaching, behaviour, communication,
knowledge, interaction) of a particular lecturer for
respective class. The student should register first in Student-
Registration page.
Lecturer login: In this, Lecturer can see the messages of the
student and feedback of a particular class with graph format
for overall feed-back and another graph for individual
categories. The lecturer should also register first in Staff-
Login page.
Collection of SMSs and Messages: First step is to collect
messages from the students in a particular subject through
SMSs and from student login. Next step is to create database
for the collected messages. Database contains number of
messages received from the students, received message, date
and time.
Corrected model: In this, there is spell checker. We can
correct the spelling mistakes in each document, if any. It
will suggest some words from dictionary. We select from
the list for changing it.
Grammar Correction: In this, we correct the grammar of a
sentence in each document, if any. It will show the correct
sentence options for changing.
Stop Word Removal: It will remove the stop-words like to,
a, an, not, the, etc. It will help for easy analyzing purpose in
sentiment analysis module.
Stemming: It is process of mapping of all the alternatives to
the ROOT word. It will identify the tense of the word. For
example, the root word “go” has the following variations –
go, went, gone.
Parsing: It will parse the data and tag the parts-of speech
for every word.
Sentiment Analyzer: This is very important module. The
system will analyze each and every message in relevant
group individually using sentiment analysis. It gives each
and every person feedback as positive or negative or average
about the lecture in graph format.
4. RESULT
The user can give the feedback in different forms. If the user
types wrong spelling or incorrect grammar it will show
immediately to user for changes. So by this correction the
analysis of text will be easier. We can show the result
immediately to the user for their feedback. The result will be
in three forms, i.e. good, bad, and average.
WORDS in sentence RESULT
Good GOOD
Not good AVERAGE
Not bad GOOD
Bad BAD
Other data/irrelevant data AVERAGE
Empty space AVERAGE
The result of this methodology is a graphical representation
in lecturer login page. We are showing different graphs for
different categories and a graph for overall status from SMS
and online feedback. We will show the messages that are
collected from SMS and suggestions from student login in
lecturer login page.

5. CONCLUSIONS
By this methodology we can give feed-back to lecturer. It
will correct spelling and grammar in text entered by the
user. We will show the result in graphical format for better
understanding to lecturer. This is useful for improvement of
his/her performance. In future this can be developed as
ANDROID-APP for simple and fast response. We can use
this method for various other categories. This is very low
cost and platform independent.
