Abstract

With the exponential growth of online marketplaces and user-generated content therein, aspect-based sentiment analysis has become more important than ever. In this work, we critically review a representative sample of the models published during the past six years through the lens of a practitioner, with an eye towards deployment in production. First, our rigorous empirical evaluation reveals poor reproducibility: an average 4-5% drop in test accuracy across the sample. Second, to further bolster our confidence in empirical evaluation, we report experiments on two challenging data slices, and observe a consistent 12-55% drop in accuracy. Third, we study the possibility of transfer across domains and observe that as little as 10-25% of the domain-specific training dataset, when used in conjunction with datasets from other domains within the same locale, largely closes the gap between complete cross-domain and complete in-domain predictive performance. Lastly, we open-source two large-scale annotated review corpora from a large e-commerce portal in India in order to aid the study of replicability and transfer, with the hope that it will fuel further growth of the field., Comment: 12 pages, accepted at ECIR 2021

47. Exploring the perception of ethnic migrants in Kolkata, India: A comparative study using sentiment analysis.

Author

Samanta, Purbita and Chattopadhyay, Subrata

Abstract

The challenges faced by ethnic migrants in urban areas highlight the importance of gaining a comprehensive understanding of their perception. This research investigates the adaptive capacities of ethnic migrants, extending the analysis beyond the first generation to explain how these communities navigate challenges in the post-COVID era. The study examines the dynamics of ethnic migration, exploring intercultural interactions and the evolving experiences of successive migrant generations using sentiment analysis techniques. The study analyzes textual data from in-depth semi-structured interviews to understand their experiences in city and sentiments about the host community. Sentiment analysis, often known as opinion mining, is used in this research to determine the emotional undertone of the third and fourth-generation Chinese and Anglo-Indian residents living in Kolkata, India. The study contributes to evidence-based strategies by identifying positive and negative sentiments associated with ethnic migrants. Results show that the frequency and polarity of the words used during the interviews significantly explain their association with the host community and their sense of belongingness. The findings of this research are significant in indicating the vitality of these communities in the city. [ABSTRACT FROM AUTHOR]

Abstract

Marketing management is one of the practical-oriented subjects in management education, which is very dynamic. In this changing and newly emerging business and marketing ecosystem, the challenge of marketing teaching pedagogy is increasing day by day. In marketing management teaching pedagogical research, there is a scarcity of integrated blended framework consisting of teaching technology and augmented learning exposure in supporting classroom teaching methodology. The study attempts to identify how various factors like theoretical knowledge, practical orientation, teaching technology and augmented learning can impact marketing management education's learning outcome in the Indian context. Current research has also tried developing and examining a structured framework that may strengthen the classroom teaching environment. This article is based on empirical data of 693 marketing and sales professionals who are mostly alumni from topmost Indian B-schools. Exploratory factor analyses and structural equation modelling, and path analysis are being done to test the conceptual research model. The results of this article demonstrate how contemporary integrated classroom teaching can boost the marketing management learning outcomes with a proper blend of augmented learning exposure, out-of-class exercises and teaching technology in an Indianized way.
