Sentiment analysis on Bangla conversation using machine learning approach

Nowadays, online communication is more convenient and popular than face-to-face conversation. Therefore, people prefer online communication over face-to-face meetings. Enormous people use online chatting systems to speak with their loved ones at any given time throughout the world. People create massive quantities of conversation every second because of their online engagement. People's feelings during the conversation period can be gleaned as useful information from these conversations. Text analysis and conclusion of any material as summarization can be done using sentiment analysis by natural language processing. The use of communication for customer service portals in various e-commerce platforms and crime investigations based on digital evidence is increasing the need for sentiment analysis of a conversation. Other languages, such as English, have well-developed libraries and resources for natural language processing, yet there are few studies conducted on Bangla. It is more challenging to extract sentiments from Bangla conversational data due to the language's grammatical complexity. As a result, it opens vast study opportunities. So, support vector machine, multinomial naïve Bayes, k-nearest neighbors, logistic regression, decision tree, and random forest was used. From the dataset, extracted information was labeled as positive and negative

Smoothing the Lies: The Distinctive Effects of Patent Characteristics on Examiner and Applicant Citations

This is the peer reviewed version of the following article: Azagra‐Caro, J. M., Mattsson, P., & Perruchas, F. (2011). Smoothing the lies: The distinctive effects of patent characteristics on examiner and applicant citations. Journal of the Association for Information Science and Technology, 62(9), 1727-1740., which has been published in final form at http://doi.org/10.1002/asi.21574. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving."Patent citations added by examiners are often used as indicators of technological impact and knowledge flows, despite various criticisms. In this study we analyze the distribution of examiner patent citations according to patent characteristics in order to show their limitations. According to our findings, the number of applicant citations included is dependent on the science-base of the technology. However, this gets masked by the citations added by patent examiners, who smooth the distribution of citations across technology classes and include the same number of citations regardless of whether applicants cite any references. Some researchers have called for the use of applicant rather than examiner patent citations as indicators of technology impact and knowledge flows. Nevertheless, we show that the former also have important caveats, because applicants may increase the number of citations in international patents and when there are coapplicants. The implication is that analysts should consider a context-driven use of citation-based indicators.We thank the Valencian R&D Consultancy Council for funding the data gathering on which the study relies.

Travelers, Translators, and Spiritual Mothers: Yoga, Gender, and Colonial Histories

Analyzing the work of women traveling to India in the nineteenth and early twentieth centuries, this essay explores the intersections of gender, race, and colonial history and connects them to contemporary cultures of yoga. It suggests that analyzing gender in colonial contexts provides a way to understand the dynamics of yoga cultures more fully, and to place them within a historical and cultural frame. As a mind-body practice that was initially becoming consumed by Western audiences and by women in the late nineteenth century and that continues to be a potent and popular practice globally, yoga in its various forms and representations can reflect how the dynamics of colonialism endure and are culturally sustained

”Mother language for me is a part of life, a part of human being” : A qualitative study of how preschool teachers reason about the importance and development of the mother language of preschool children with a mother language other than Swedish

Syftet med denna studie är att undersöka hur förskolans pedagoger resonerar kring betydelsen och utvecklandet av modersmålet hos barn med annat modersmål än svenska. En kvalitativ forskningsansats valdes med semistrukturerade intervjuer. Åtta pedagoger som deltog i studien bestod av förskollärare och barnskötare. Studiens resultat analyserades utifrån ett sociokulturellt perspektiv. Resultatet visar att metoder som förskolans pedagoger använder är att tala på barnens modersmål och att använda digitala verktyg för att utveckla modersmålet. Miljöns utformning bestod av material som tvillingböcker samt språkhörna med alfabet på barnens modersmål för att gynna barns läs- och skrivutveckling på sitt moderrsmål. Slutsatsen är att modersmål ses som tillgång. Varierande metoder och material används som till exempel digitala verktyg, tvillingböcker, TAKK och bildstöd, samtidigt finns det utmaningar vilket är bland annat begränsad ekonomi och tidsbrist.
