In this exploratory study of English-Hindi code-switching on Twitter, we automatically create a large corpus of code-switched tweets and devise techniques to identify the relationship between successive components in a code-switched tweet. More specifically, we identify pragmatic functions such as narrative-evaluative, negative reinforcement, translation or semantically equivalent statements, and so on characterizing the relation between successive components. We analyze the difference\/similarity between switching patterns in code-switched and monolingual multi-component tweets. We observe strong dominance of narrative-evaluative (non-opinion to opinion or vice versa) switching in case of both code-switched and monolingual multi-component tweets in around 40% of cases. Polarity switching appears to be a prevalent switching phenomenon (10%) specifically in code-switched tweets (three to four times higher than monolingual multi-component tweets) where preference of expressing negative sentiment in Hindi is approximately twice compared to English. Positive reinforcement appears to be an important pragmatic function for English multi-component tweets, whereas negative reinforcement plays a key role for Devanagari multi-component tweets. Our results also indicate that the extent and nature of code-switching also strongly depend on the topic (sports, politics, etc.) of discussion.<\/jats:p>","DOI":"10.1145\/3314935","type":"journal-article","created":{"date-parts":[[2019,7,24]],"date-time":"2019-07-24T12:05:56Z","timestamp":1563969956000},"page":"1-28","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":12,"title":["Identifying and Analyzing Different Aspects of English-Hindi Code-Switching in Twitter"],"prefix":"10.1145","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2486-7608","authenticated-orcid":false,"given":"Koustav","family":"Rudra","sequence":"first","affiliation":[{"name":"Department of CSE, IIT Kharagpur, India"}]},{"given":"Ashish","family":"Sharma","sequence":"additional","affiliation":[{"name":"Microsoft Research Lab, Bangalore, India"}]},{"given":"Kalika","family":"Bali","sequence":"additional","affiliation":[{"name":"Microsoft Research Lab, Bangalore, India"}]},{"given":"Monojit","family":"Choudhury","sequence":"additional","affiliation":[{"name":"Microsoft Research Lab, Bangalore, India"}]},{"given":"Niloy","family":"Ganguly","sequence":"additional","affiliation":[{"name":"Department of CSE, IIT Kharagpur, India"}]}],"member":"320","published-online":{"date-parts":[[2019,7,23]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/COMSNETS.2017.7945452"},{"volume-title":"Proceedings of the 26th International Conference on Computational Linguistics. 1211--1219","year":"2016","author":"Al-Badrashiny Mohamed","key":"e_1_2_1_2_1"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/1367006913489198"},{"volume-title":"Managing Multilingualism in India: Political and Linguistic Manifestations","author":"Annamalai Elayaperumal","key":"e_1_2_1_4_1"},{"volume-title":"One Speaker, Two Languages","author":"Auer Peter","key":"e_1_2_1_5_1"},{"volume-title":"Proceedings of the 8th International Conference on Language Resources and Evaluation (LREC\u201912)","year":"2012","author":"Bakliwal Akshat","key":"e_1_2_1_6_1"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.3115\/v1\/W14-3914"},{"volume-title":"Proceedings of the Workshop on Modeling, Learning and Mining for Cross\/Multilinguality (MultiLingMine\u201916)","year":"2016","author":"Banerjee Somnath","key":"e_1_2_1_8_1"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.3115\/v1\/W14-3902"},{"volume-title":"Pragmatic functions of code-switching among Basque-Spanish bilinguals.
