Research Topic : Named Entity Recognition and Classification for Telugu Language
Research Abstract : Named Entity Recognition (NER) aims to classify each word of a document into predefined target Named Entity (NE) classes and is now-a-days considered to be fundamental for many Natural Language Processing (NLP) tasks such as Information Retrieval, Machine Translation, Information Extraction, Question Answering systems and others. For English a lot of work has already done in field of NER, where capitalization is a major clue for rules, whereas Indian Languages do not have such feature. This makes the task difficult for Indian languages especially Telugu Language as it is highly inflectional and agglutinative in nature. The NER system makes use of the different contextual information of the words along with the variety of features that are helpful in predicting the different NE's classes, such as Person name, Location name, Organization name, monetary expressions, dates, numerical expressions etc.

Research Topic: Integrating Digital Forensic Capabilities in Cloud for Incident Handling
Research Abstract: The likelihood of attacks and security breaches occurring in cloud is very high which underlines the need for digital forensic investigation in IaaS based Cloud environment. Performing forensics in cloud is challenging and even different from traditional digital forensics because of cloud virtualization, elasticity, multi-tenancy, trust and legal issues and physical inaccessibility. Our work focuses on resolving these challenges and applying digital forensic science in Infrastructure as a Service (IaaS) delivery model.

Research Topic: Analysis of Temporally Evolving Social Network Patterns
Research Abstract: In this work, we propose to investigate different techniques for identifying temporal patterns and events in social networks that evolve over time. We present a framework for detecting the evolution of dynamic social communities, along with tracking the events and transitions related to communities. These events can be considered as building blocks for pattern detection in networks with evolving communities. These detected events and transitions could then be used for predicting the future patterns of these social networks.

Research Topic:  Securing the Internet of Things Environment against RPL (Routing Protocol for Low power and Lossy Network) Attacks

Research Abstract: Internet of Things (IoT) is network of uniquely identified devices that have the ability to talk to each other without requiring human intervention. IoT devices are constrained which makes it difficult to implement complex security solutions on them. The communication is wireless, which also makes it susceptible to attacks. Also, the devices are mostly placed in locations which cannot be frequently accessed. These characteristics of IoT make it vulnerable to breaches in privacy and security. An effective way to prevent attacks is to have secured bootstrapping. Secure bootstrapping in IoT involves design of light weight cryptographic algorithms. RPL is the Routing protocol used in LLNs in IoT, which is vulnerable to several security attacks. Hence, it is important for an IoT network to have a holistic system to address the RPL attacks. The research topic aims to develop such a system, which can identify the RPL attacks, take action to counter it and also design secure bootstrapping algorithms for authentication of new nodes joining the IoT network.

Research Topic: Opinion Mining Challenges of Social Media Content & Sentiment Polarity Detection.
Research Abstract: Experiences and viewpoint expressed by others have always been important part of decision making process. In current era very large pool of public opinion is available on social media about certain event. These web contents are unstructured data set and a rich source for not only commercial exploitation but also for psychological & sociopolitical research. Our proposed research aims to find an efficient method to extract important features/ aspect about a particular event from social media message and then do the features based sentiment analysis about the same. The proposed method can be adapted to work for text from other online media as well.
