OBJECTIVE
The centre addresses the challenges of research problems such as
 summarizing and analyzing the sentiment of the vast amounts of user-
generated content
 Analyzing the information in social networking websites
 Online recommendation system
 Ontology Ranking
 Dynamic Web service composition
 Dynamic data fusion of heterogeneous attributes

I. Mining Frequent Patterns without Tree
Generation
 The frequent patterns are generated without any candidate set or tree
construction.
 This methodology encodes the database using numerical approach and
reduces the size of the encoded database to a great extent. .
 This algorithm leads to the reduction in both space and time complexity.

II. Sentiment Analysis In Twitter Using Scoring
Model
 Twitter is one of the most fashionable microblogging that permits users to
express their views on sports, politics, modern technologies, movies and
spirituality and so on.
 It is hard to place the sentiment polarity of the tweets. In this paper new
scoring methodology to find the sentiment polarity of the twitter messages
is proposed.
 Emotions and shortened words are integrated to increase the significance of
the proposed scoring technique.

II. Sentiment Analysis In Twitter Using Scoring
Model
The following work has been done
 We are now monitoring food-price related tweets from January 2015 around 5000
tweets and analyze the impact of food price crises.
 Statistical scoring model is used to classify the relevant tweets, depending on the
sentiment they express (i. e. “positive tweet” “negative tweet” and “neutral tweet”).
Sample of tweets was then used to train to classify the tweets in the correct category
and identify the sentiment of new tweets.
 Data mining techniques are used to extract the relevant keywords/ features related to
food price crises. From the twitter conversations, these keywords/features are analyzed
on how to correlate the impact of food price crises – developing an efficient new
algorithm for clustering the features

Model Incorporating Language & Non-language Features”, Applied for
International Journal of Information Retrieval Research.

EXPERIMENTAL RESULTS
The overall score of the tweet is greater than zero, the tweets is classified as a
positive tweet, less than zero then classified as a negative tweet and closer to zero means
neutral tweet. Some sample tweets with the sentiment orientation is presented in the
Table 1.
Table 1. Sample tweets and Sentiment Polarity
Sl. No. Tweet Score Sentiment Polarity
1 Election this could get nasty -0.2000 Negative
2 I never reject this work 0.2200 Positive
3 The book is gud 0.1667 Positive
4
RT annual Spring Game is set for Saturday April at pm
ET in Commonwealth Stadium
0.0100 Neutral
5
With no respect for Indian cricket should be barred
from Villiers should go from IPL or be thrown out
-0.0111 Negative

III. Elimination of Redundant Association Rules –
An Efficient Linear Approach
 Association rule mining plays an important role in data mining and knowledge
discovery.
 Traditional association rule mining algorithms generate lots of rules based on the
support and confidence values, many such rules thus generated are redundant.
 The eminence of the information is affected by the redundant association rules.
 The proposed algorithm removes redundant association rules to improve the quality of
the rules and decreases the size of the rule list.
 It also reduces memory consumption for further processing of association rules.

RECOMMENDATION SYSTEM
Objective
- Capture the user intent and recommend the web pages the
contains user expected information.
- An important challenge of such system must include a need of
being self-adaptive because the needs of online user may
change dynamically and also design an accurate classifier for
improving the accuracy of recommendation system.
