0 likes93 views
This document proposes a system to filter unwanted messages from walls and block non-legitimate users in online social networks. It uses machine learning for content-based filtering of messages. Short text is classified and filtering rules are provided to block certain content. Blacklists are also used to prevent some users from posting messages temporarily. The proposed system aims to provide privacy and control over the content visible on users' walls.

Abstract— Today’s life is totally based on Internet. Now a
days people cannot imagine life without Internet.
Information and communication technology plays vital role
in today’s online networked society. In today’s life, we are
very close to the online social networks. Online social
networks are used for posting and sharing information
across various social networking sites. But user’s privacy is
not maintained by online social networks. For maintaining
users sensitive information’s privacy online social networks
provides little or no support. For filtering unwanted
messages we propose a system using machine learning
(ML). Using machine learning in soft classifier content
based filtering performed. In proposed system filtering rules
(FR’s) are provided for content independent filtering..
Blacklists are used for more flexibility by which filtering
choices are increased. Proposed system provides security to
the Online Social Networks.
Key words: Online Social Networks, Machine Learning,
Information Filtering, Content based Filtering
I. INTRODUCTION
Online social networks are today’s are very popular
interactive medium for communication, sharing and
dissemination of large amount of human life information
across various social networking sites. In communication,
exchange of different types of content like text, image,
audio, and video data. For useful information extraction
filtering is used. In OSN’s for posting or commenting or
posts on particular public or private area called walls. Using
information filtering user can control the messages written
on their walls, by filtering out unwanted messages. Today
OSN’s provide little support or no support for unwanted
messages. But no content based filtering supported.
Therefore, It is hard to prevent unwanted messages, such as
political or vulgar. Therefore Proposed a system for filtering
or preventing unwanted messages called Filtered Walls
(FW’s). Use Machine Learning (ML) text categorization
techniques[5]. For short text classification use radial basis
function networks (RBFN), In managing noisy data[6]. We
insert two level classification strategy, in first level RBFN
categorize short messages as a neutral and non-neutral; in
the second, Non-neutral messages are classified and
correctness estimate are produced. In proposed system
filtering rules are provided. FR’s are the rules in which user
can stste what contents are not displayed on their walls. In
addition the system used user defined Blacklists (BL’s). In
which it makes lists of users that are temporarily prevented
to post any type of messages on a user wall. Proposed
system filters unwanted messages from OSN user walls. On
the basis of message content and message creator
relationship.
II. LITERATURE SURVEY
We are using Content based filtering and Policy based
Personalisation for filtering unwanted or vulgar messages or
text from users Online Social Networks (OSN) walls. So for
that purpose we are surveying the literature in both fields.
The Main motive of this paper is to implement an
architecture which provides customized content based
filtering for OSN’s, based on machine learning techniques.
Our related work is related with both content based filtering
and Policy based personalisation.
For Example: In Facebook user states who is
allowed to insert messages on their walls (like friends,
friends of Friends and Groups of friends) but no content
based filtering are supported.
A. Content based Filtering:
In content based filtering, each user is assumed to work
separately. A content based filtering collects the information
of items based on the relationship between the item’s
content and the user choices. An electronic mail is well
known example of Content based filtering. Only textual data
is processed in content based filtering, Therefore content
based filtering is closely similar to Text Classification.
Content Based filtering is based on the use of machine
learning paradigm. According to machine learning paradigm
a classifier is automatically induced by learning from a sets
of predefined examples. The Information Retrieval is
presented by P.W. Foltz and S.T. Dumais [1].There is no
information filtering in this approach.in our approach we are
using information filtering. Information retrieval is very
much similar to information filtering. filtering involves
process of removing information from stream, while IR
involves process of finding information in that stream.
B. Policy Based Personalization:
Policy based personalization is useful in different types of
contexts. In Online Social Networking sites user defined
policies can define how communication between two parties
or more parties can handled. The policy based
personalization mostly focuses the Twitter. It categorizes the
each tweet and only shows those tweets which are of user’s
interest. Policy based personalization shows the ability of
use to filter unwanted messages based on filtering criteria
suggested by him or the customized settings chosen by him
B. Sriram, D.fuhry, E.Demir, H. Ferhatosmanogly,
and M. Demirbas [2], our paper describes classification of
tweets into general. our approach allows settings of filter
rules according to a variety criteria’s described by him and
classifies the text into various pre-defined sets of classes like
various categories like sports, politics, Bollywood etc.
L. Fang and K. LeFevre [3], this paper is related to
privacy control but no facility for stopping anyone for](https://image.slidesharecdn.com/ijsrdv3i100606-160213072644/85/Filter-unwanted-messages-from-walls-and-blocking-nonlegitimate-user-in-osn-1-320.jpg)

posting something on wall. Our approach can stop posting
particular categories as per users choice.
Fong, P.W.L., Anwar, M.M., Zhao, Z. [4], this
paper describes policies such as topology based, history
based. So that it is time consuming our approach presents
content based filtering and Policy based personalization.
III. PROPOSED SYSTEM
From above literature survey we can conclude that there is
no any prevention on post which is posted by friends or any
person. So, if any person is not interested to see or to read
specific category of messages then he cannot apply any filter
on their walls. In this situation he can receive any type of
messages.in our proposed system we apply prevention to
messages by using or providing filtering rules. The main
aim of system is to prevent or filter unwanted messages
from user walls. In proposed system, filtering are supported
by content based preferences. The main part of proposed
system is content base message filtering(CBMF) and the
short text classifier module. The second element that is short
text classifier are used to categorize messages according to
set of different categories. In comparison, the first element
uses the message categorization provided by short text
classifier to implement filtering rules specified by the user.
For enhancing the filtering process Blacklist can also be
used. Blacklists are the list of users which are temporarily
prevented to post messages or text on user walls.
In our system architecture we designed a filter to
discard those messages which are vulgar in nature and
prevented to be displayed on another users wall. If User1
wants to posts some content on someone’s wall then before
it will display on that user wall, it will be checked that
whether the content is vulgar, we have provided predefined
dataset which include those words which are vulgar in
nature. If User1 data matched to the dataset then this
message is vulgar in nature so it cannot displayed on wall
and that user who wants to write message will be blocked.
This process is carried out through user defined rules and in
some cases BlackList(BL) are also used.

IV. CONCLUSION
In our proposed system, Filtered wall is a system to prevent
or filter unwanted or unnecessary messages from online
social networks walls. This system approach decides when
user should be inserted into a blacklist. Filtered wall has a
wide variety of applications in OSN wall. In future, more
work is needed on further improving the performance
measures.
