# The Corpus of Singapore English Messages (CoSEM) ![enter image description here][1] ### Overview The Corpus of Singapore English Messages (CoSEM) is a corpus of online text messages collected between 2016 and 2022, compiled and managed by a group of scholars who share an interest in Colloquial Singapore English (CSE) research. <br /> #### Features - Contains the following metadata (as reflected in tags) - age - gender - race - nationality - year of collection - year of utterance - in hierarchical text format: primed for concordance software including AntConc, CasualConc <br /> <br /> ### License The CoSEM follows the CC BY-NC-SA 4.0 License, meaning that you are free to: - Share — copy and redistribute the material in any medium or format; - Adapt — remix, transform, and build upon the material. The licensor cannot revoke these freedoms as long as you follow the license terms. Under the following terms: - Attribution — You must give appropriate credit , provide a link to the license, and indicate if changes were made . You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use. - Non-Commercial — You may not use the material for commercial purposes. - ShareAlike — If you remix, transform, or build upon the material, you must distribute your contributions under the same license as the original. No additional restrictions — You may not apply legal terms or technological measures that legally restrict others from doing anything the license permits. <br /> ### Disclaimer The public version of the CoSEM (see 'Corpus Version' below) has some limitations. For example, based on our initial assessment, the scrubber does its work for the most part. However, we note that it scrubs non-name information that might be important for analyses. For example, (a) below becomes (b). Furthermore, we observed that it only scrubs information from the [`scrubadub`](https://scrubadub.readthedocs.io/en/stable/ "scrubadub") package. As such, we recommend that you exercise caution in using the public version of the corpus. We put forward our intention of contributing to the scholarly community by showing whatever we can at this time. We thank you for your patience. <br /> ``` (a) <COSEM:18MF02-9431-23CHF-2014> Why u still dunwan go homr (b) <COSEM:18MF02-9431-23CHF-2014> Why u still {{NAME}} go {{NAME}} ``` <br /> <br /> <br /> ### Overview #### Collection methodology Please check out [our overview paper](https://github.com/wdwgonzales/CoSEM/tree/main/Overview%20paper). <br /> <br /> #### Personal Data Scrubbing Ensuring the privacy for messaging data is paramount, and as such, we try our best to adopt a strict standard in dealing with sensitive data in the message itself. We utilize the [`scrubadub`](https://scrubadub.readthedocs.io/en/stable/ "scrubadub") package in Python as well as a customized RegEx script to remove sensitive data as much as we can. For example, any detected email address will be replaced by the code {{EMAIL}}. This process gives at least some protection against publishing sensitive data. While we remove such confidential information, it is generally impossible to remove all sensitive data with any custom RegEx-based script or computation-based, especially one trained with machine learning methods like scrubadub. We did this to lower the anxiety of contributors and protect their privacy. We thank Tao Chen and Min-Yen Kan for the disclaimer template. <br /> #### Corpus metadata or tag format Every line of utterance has been tagged with an identifier tag. The tag format allows for easy identification of a line of utterance within the corpus, and for easy interpretation of relevant metadata. For example, the tag < 17CF15-40341-20CHF-2016 > shows that the utterance was collected in the year 2017 by a Chinese female with identification number 15; the utterance is line 40341 in the corpus; and the line was produced by a 20-year-old Chinese Singaporean female in 2016. <br /> <br /> #### Corpus Version The current public version stands at 10.9 million tokens (as of September 17, 2023). It is anonymized using the [`scrubadub`](https://scrubadub.readthedocs.io/en/stable/ "scrubadub") package as well as customized `RegEx` scripts. As with any type of automated scrubbing, there is a chance that some utterances are not properly scrubbed, in which case, we ask the corpus users to exercise tact in using the data, anonymizing unscrubbed private information if they intend to present examples that contain them. <br /> ##### Plans for future versions - more targetted scrubs - reduction of mis-scrubbed tokens - increased size <br /> <br /> ### Team - [Assoc.

It documents the process of compiling and organizing CoSEM and describes the corpus’s initial structure and composition. We further discuss the social variables used in tagging the data, as well as ethical challenges, advantages, and disadvantages unique to online message datasets. In addition, we present preliminary analyses of two selected CSE features: (1) the Hokkien-derived expression (bo)jio and (2) sentence-final adverbs (already, also, only). We concluded the article with notes on future directions.
