Overview of the track on Sentiment Analysis for Dravidian Languages in Code-Mixed Text

Abstract: Sentiment analysis of Dravidian languages has received attention in recent years However, most social media text is code-mixed and there is no research available on sentiment analysis of code-mixed Dravidian languages The Dravidian-CodeMix-FIRE 2020, a track on Sentiment Analysis for Dravidian Languages in Code-Mixed Text, focused on creating a platform for researchers to come together and investigate the problem There were two languages for this track: (i) Tamil, and (ii) Malayalam The participants were given a dataset of YouTube comments and the goal of the shared task submissions was to recognise the sentiment of each comment by classifying them into positive, negative, neutral, mixed-feeling classes or by recognising whether the comment is not in the intended language The performance of the systems was evaluated by weighted-F1 score

A Graph-Based Security Framework for Securing Industrial IoT Networks From Vulnerability Exploitations

Abstract: Industrial IoT (IIoT) refers to the application of IoT in industrial management to improve the overall operational efficiency. With IIoT that accelerates the industrial automation process by enrolling thousands of IoT devices, strong security foundations are to be deployed befitting the distributed connectivity and constrained functionalities of the IoT devices. Recent years witnessed severe attacks exploiting the vulnerabilities in the devices of IIoT networks. Moreover, attackers can use the relations among the vulnerabilities to penetrate deep into the network. This paper addresses the security issues in IIoT network because of the vulnerabilities existing in its devices. As graphs are efficient in representing relations among entities, we propose a graphical model representing the vulnerability relations in the IIoT network. This helps to formulate the security issues in the network as graph-theoretic problems. The proposed model acts as a security framework for the risk assessment of the network. Furthermore, we propose a set of risk mitigation strategies to improve the overall security of the network. The strategies include detection and removal of the attack paths with high risk and low hop-length. We also discuss a method to identify the strongly connected vulnerabilities referred as hot-spots. A use-case is discussed and various security parameters are evaluated. The simulation results with graphs of different sizes and structures are presented for the performance evaluation of the proposed techniques against the changing dynamics of the IIoT networks.

A Survey of Current Datasets for Code-Switching Research

Abstract: Code switching is a prevalent phenomenon in the multilingual community and social media interaction. In the past ten years, we have witnessed an explosion of code switched data in the social media that brings together languages from low resourced languages to high resourced languages in the same text, sometimes written in a non-native script. This increases the demand for processing code-switched data to assist users in various natural language processing tasks such as part-of-speech tagging, named entity recognition, sentiment analysis, conversational systems, and machine translation, etc. The available corpora for code switching research played a major role in advancing this area of research. In this paper, we propose a set of quality metrics to evaluate the dataset and categorize them accordingly.

Proceedings of the International Conference on Advances in Computing, Communications and Informatics

Abstract: Globalization tends to be most perceptible and observable in almost every facet of life mainly due to the emergence of new digital technologies of computing and communications. At the same time, informatics with its strong focus on providing fast and ready access for human based on these developments in computing and communications plays more very crucial role in people's lives and permeates all it in all respects, from entertainment to healthcare and from databases to e-governance. The International Conference on Advances in Computing, Communications and Informatics (ICACCI'12) was held in Chennai, India during August 3-5, 2012 and hosted at RMK Engineering College, Chennai. ICACCI provides an international forum for exchange of ideas among interested researchers, students, developers, and practitioners in the areas of computing, communications, and informatics. ICACCI'12 was organized in association with National Association of Software and Services Companies (NASSCOM), Offenburg University of Applied Sciences, Germany; Computer Society of India (CSI), The International Society for Computers and Their Applications, Inc. (ISCA), USA; International Neural Network Society (INNS), India Chapter; Indian Association for Medical Informatics (IAMI), Software process improvement network (Spin); and Research Publishing Services (RPS), Singapore.
