DESCRIPTION

I created this presentation to present my research work to the committee. My research was on extracting tweets and analyzing it with an previously created ontology model. The results of the ontology model will help in identifying the domain area of the problem for which use had shared negative sentiments on tweeter. This system along with the ontology model developed for Postal service domain. The next step in research will be to generate automated responses on twitter to the user who shares negative sentiments.

OVERVIEW Introduction Problem Background Research Proposed Solution Architecture Results Conclusion

INTRODUCTION Social media connects organizations and customers. i.e.

Twitter, Facebook and Google+.

Use of social media: Organization

Get product feedbacks Promote brand value Directly connect with customers.

Customer Get product updates Build and connect with product user community Share experience

PROBLEM Organizations:

Read direct feedbacks Generate report of satisfaction/dissatisfactions Communicate

NO Interactive communication for user’s complaint on

social media

A system is needed Can extract social media content & analyze Identify the reason for problem Generate the response on the social media platform

Ontology building

PROPOSED SOLUTION An ontology-based sentiment analysis model and an

automated response generator system.

Architecture of the model - three processes Ontology model creation process Sentiment analysis with ontology model (Identifying

the associated problem with the content) Automated response generator

ARCHITECTURE PROCESS 1

ARCHITECTURE PROCESS 2

ARCHITECTURE PROCESS 3

ARCHITECTURE - MODULES Data extraction: Extract data from Twitter GATE software: Extract information like nouns and

verbs from the content Protégé software: Build ontology model and to query

the model Ontology model: Consists class, subclass, objects,

object properties SentiStrength2: Identify positive and negative

sentiments tweets. SPARQL query language: Query the ontology model

and retrieve the information

CONCLUSION “We can develop a system to analyze negative

content being shared on social media platform and try to find out problem associated with it. After understanding the problem, it is possible to generate predefine reply for it on social media.”

This model will help in building foundation for further research on the use of ontology for sentimental analysis.
