"abstract": "This study examines the evolutionary trajectory of graphicons in a 13-year corpus of comments from BiliBili, a popular Chinese video-sharing platform. Findings show that emoticons (kaomoji) rose and fell in frequency, while emojis and stickers are both presently on the rise. Graphicon distributions differ in comments and replies to comments. There is also a strong correlation between the types of graphicons used in comments and their corresponding replies, suggesting a priming effect. Finally, qualitative analysis of the 10 most-frequent kaomojis, emojis, and stickers reveals a trend for each successive graphicon type to become less about emotion expression and more integrated with platformspecific culture and the Chinese language. These findings lend partial support to claims in the literature about graphicon evolution.",

"text": "Graphicons are graphical icons used in text-based computer-mediated communication (Herring & Dainas, 2017) . From the first use of :-) in 1982 (Evans, 2017) to the varied and colorful stickers on social media today, graphicons have changed dramatically. ASCII emoticons, the first graphicons, were composed of keyboard symbols and were typically used for expressing emotion. Emoticons in the Western context emphasize the mouth and are read at a 90-degree angle to the words (e.g., :-) for a smiley), while kaomoji (literally 'face letters'), a style of emoticon that arose in Japan and also became popular in China, are read in-line with words and emphasize the eyes (e.g., ^_^ or ^^) (Katsuno & Yano, 2002) . Kaomojis express not only emotions, but also actions, objects, and story lines. 1 1 http://kaomoji.ru/en/, retrieved April 5, 2022.",

Emoji are more colorful, more representational (as opposed to schematic), and express a wider array of concepts than ASCII emoticons. Stickers, which were introduced a few years after emojis, take these trends further (Konrad et al., 2020) . Usually larger than emoticons and emojis, stickers may include text; this is typical of stickers used on Chinese social media (e.g., see the examples in de Seta, 2018; Ge, 2020) . Stickers are character-driven illustrations or animations that are typically offered as thematic sets on social media platforms (de Seta, 2018), although social media users in China may also create their own stickers (Ge, 2020) .",

"text": "As graphicons continue to grow in popularity worldwide and shape social media and mobile communications, it is important to understand how and why they evolve, and the implications of their evolution for where they are headed in the future. Konrad et al. (2020) posit that graphicons tend to follow an evolutionary trajectory consisting of three phases: an early phase, a high (or peak) phase, and a phase of decline and/or conventionalization. One of the main criteria for determining which phase a graphicon is currently in is frequency of use; another is pragmatic changes in graphicon use. For Western graphicons, according to Konrad et al. (2020) , emoticons are in the third phase, emoji are in the second phase, and stickers are in the first phase. The authors predict that emoji will eventually reach the third phase, following the path of emoticons, and that stickers may eventually reach the second (and eventually the third) phase and overtake emoji in popularity.",

Pavalanathan and Eisenstein (2016) analyzed emoticons and emoji on Twitter in the 17 months after emoji were first introduced on the platform. They found that emoticon use dramatically decreased as emoji use increased. Furthermore, a number of studies have reported that emoticons have become conventionalized as a type of punctuation (Markman & Oshima, 2007; Provine et al., 2007) . That is, emoticons have declined in frequency of use and have become conventionalized, evidence that they are in the third phase of Konrad et al.'s (2020) evolutionary trajectory.

They also noted some differences: participants described emojis as better suited for expressing emotion, whereas stickers were considered more specific and better at expressing the user's personality. However, Konrad et al. (2020) did not quantify emoji and sticker use over time. What is needed is a longitudinal corpus of data involving the use of emoticons, emojis, and stickers, in order to be able to map the evolutionary trajectory of the three types of graphicons.",

They are designed in creative ways by and for Chinese social media users to enliven conversations (Ge, 2020) , resolve the tension between the openness of social media and constraint-bounded social norms (Zhang et al., 2021) , and playfully subvert reality and avoid internet surveillance and censorship (Li & Zhu, 2019) . The design of graphicons carries rich cultural messages (de Seta, 2018) and interacts with the Chinese national character (Li & Zhu, 2019) . Users of Chinese social media use the umbrella term \u8868\u60c5 Biaoqing (a contraction of \u8868\u8fbe\u60c5\u611f 'expressing emotions') for all types of graphicons, suggesting a popular understanding of the shared usage of graphicons for emotion expression (de Seta, 2018). Yet different types of Biaoqing are distinguished. Kaomojis were introduced to Chinese users in the mid-1990s; emojis were first used in the early 2000s in Chinese discussion boards, instant messaging services, and social networking web sites; and stickers first became available on the QQ and WeChat platforms in 2012 (de Seta, 2018).

"text": "In terms of frequency of use, Konrad et al. (2020) suggest that graphicon evolution is more advanced in Asia than in the West. They predict that stickers should be catching up with or surpassing emoji use in Asia, in contrast to the West, where stickers are still much less popular than emojis. The evidence to support this prediction so far is limited and primarily anecdotal. Fifteen years ago, Markman and Oshima (2007) reported that the use of kaomojis as punctuation was more conspicuous in Japan than the United States. Emojis are used more frequently by Chinese social media users compared to their Western counterparts (Zhang et al., 2014) ; however, comparable statistics about the frequency of sticker use have not been found. Several studies have pointed out that stickers are now very popular among Chinese social media users (e.g., de Seta, 2018; Ge, 2020), but their frequency has not been compared with that of emojis. In this paper, we quantify the relative frequency of the three different types of graphicons in Chinese social media over time.",

The users of the platform are mainly under the age of 35, 2 and its average monthly active users reached 272 million (almost one-fifth of the Chinese population) by the end of 2021. 3 Second, the comments can include emoticons, emojis, and stickers (although stickers did not become available on the platform until 2016). Third, BiliBili is well-established, having been launched in 2009 as a platform for sharing ACG-related (Anime, Comics, and Games) content, 4 and it has expanded over the years to cover more general topics. Last and most relevant for this study, the platform preserves a historical record of the comments posted below the videos, including the graphicons in the comments, and the comments can be captured automatically.

The BiliBili show started in 2010 and soon became an important annual event on the platform. 6 The show consists of a mash-up video of content provided by professional users to celebrate the Chinese New Year, and is released on the eve of the Chinese New Year. It is considered by BiliBili users to be the online equivalent of the Spring Festival Gala produced by the China Media Group, which is broadcast annually on Chinese New Year's Eve and has the largest audience of any entertainment show in the world. Besides the show videos, the BiliBili show channel includes a number of videos related to the gala show, such as trailers, teasers, and outtakes.

"text": "The three types of graphicons in the corpus were identified using different methods. The emoticons in our corpus are Japanese-style kaomoji. The recognition of kaomojis was carried out by a semisupervised process of deep learning and manual identification. Manual annotation of kaomojis in a sample corpus was done, and this was used to train deep learning models of BiLSTM and CRF (Qin et al., 2019) to learn and develop a list of kaomoji types. Kaomoji types identified by the algorithm were checked manually. Three rounds of manual and machine iteration were conducted before a final set of kaomoji types was obtained for the purpose of examining kaomoji use in the corpus. The set of sticker types was developed based on the package of BiliBili stickers available on GitHub. 7 The set of Yellow Faces [\u5c0f\u9ec4\u8138 ] from the GitHub sticker package (see contains a number of graphicons that we reclassified as emojis, as described below. The set includes three kinds of images: 1) iconic representations of objects (e.g., Koi [\u9526\u9ca4] , the second from the top left in Figure 1) ; 2) yellow faces that are more elaborated than Unicode emojis (e.g., Astonished face [\u60ca\u8bb6], the second from the top right; and 3) stickers that are character-driven (e.g., the Laigu [\u6765\u53e4] series of three girls expressing contemplation [\u6c89\u601d] (the third from the bottom right), dullness [ \u5446 \u6ede ] (second from the bottom right), and doubt [\u7591\u95ee] (bottom right). However, the iconic images and yellow faces are displayed in the corpus the same size as emojis, which are smaller than stickers, and they are not character-driven. Therefore, we removed them from the sticker package and added them to the set of emojis prior to analysis. The set of emojis also includes Unicode emojis from the Python emoji module with a character length of 1.",

"text": "Further, graphicon usage differs in comments and replies, as summarized in Figure 5 . Kaomojis and stickers appear more frequently in comments, while emojis are used with similar frequency in comments and replies. Meanwhile, as displayed in Figure 6 , a consistent pattern is found whereby more graphicons were used in comments than in replies every year except for 2022. It is also worth noting that stickers were available on the platform in 2016, but they were not used in replies until 2018; the reasons for this lag are unclear. Another interesting phenomenon is the strong correlation between the frequency of each graphicon type in the comments and their corresponding replies. This is evident for kaomojis in Figure 7 and for emojis in Figure 8 . Frequencies for stickers are not presented here because stickers were not available on BiliBili until 2016. The years of the replies in Figures 7 & 8 refer to the year when the corresponding comments were made rather than the year when the replies were made (as in Figure 6 ). For instance, for a reply made in 2022 to a comment from 2010, the year of the reply was counted as 2010 in Figures 7 & 8 but counted as 2022 in Figure 6 . The frequencies of kaomoji usage in comments and replies ( Figure 7) show a very similar pattern; the correlation is 0.93. The frequencies of emojis ( Figure 8) show a less consistent pattern, but the correlation between comments and replies is still strong at 0.89. The strong correlations between graphicon usage in comments and replies suggest a \"priming effect\" (Molden, 2014) of graphicon usage, meaning that the occurrences of graphicons in comments have an impact on the usage of graphicons in corresponding replies.",

The types and tokens of emojis and stickers are both on the rise, although stickers do not seem to be overtaking emojis. It is highly possible that emojis have not reached their peak yet. Meanwhile, features of stickers, such as specific references and more detailed graphics, are increasingly being incorporated into emoji design (e.g., the Astonished face in Figure 1 ). If this trend continues, it is likely to expand the functions of emojis and blur the distinction between emojis and stickers. The icons in the set of Yellow Faces in the GitHub package of BiliBili stickers that we reclassified as emojis (as discussed in Section 3.2) are somewhat ambiguous between the two graphicon types. Meanwhile, the fact that more than one sticker is used per message suggests that users are borrowing from emojis the practice of repeating graphicons in one message. Thus the interrelation of emojis and stickers, as the examples and statistics in this study show, is more complex than one replacing the other.",

Kaomojis appeared more frequently in replies that were directed at individuals than in comments directed at more general readers. It remains to be explored further using both qualitative and quantitative methods how and why graphicon are used in different ways in comments and replies. Furthermore, we found that more kaomojis and stickers were used in comments, but the use of emojis was roughly the same in comments and replies.

It provides support for Konrad et al.'s (2020) evolutionary model concerning the relationship between emoticons (kaomoji) and other graphicons. However, the BiliBili data do not show stickers leading or taking over from emoji, contrary to Konrad et al.'s intriguing speculation that Chinese graphicons would show that trend. Moreover, our qualitative analysis of the top 10 most frequently used graphicons reveals a trend of graphicon evolution from general emotion expression to meanings localized in the discourse practices of the BiliBili platform. Further, our analysis of a large longitudinal dataset went beyond reporting overall frequencies of occurrence to explore more finegrained distinctions between types and tokens and differences in graphicon usage between comments and replies to comments. We also provided statistical evidence for priming effects on graphicon usage in comments and replies.

"text": "A number of limitations potentially affect the generalizability of the patterns of graphicon evolution identified in this study. First, trends in Chinese graphicon usage might differ on a different platform such as WeChat or Weibo, because Chinese social media users are inclined to use platform-specific sets of graphicons. Kaomoji usage is likely more frequent on BiliBili than on any other platform, given that the platform was initially set up to share Japanese anime, comics, and games. Stickers from users' collections cannot be used on BiliBili like they are on WeChat and Weibo. Meanwhile, only a very limited number of sticker sets are free to users, which is likely to have an impact on the varieties of stickers in use. For instance, all of our top 10 stickers are from free sets rather than paid ones. The landscape of sticker usage in WeChat or Weibo, therefore, could be very different. Meanwhile, a majority of BiliBili users are under the age of 35, and this demographic might use graphicons differently from older groups. Second, our data center on the topic of the Chinese New Year, which is both a strength and a limitation of our study. The topic provided straightforward clues for interpreting the meaning of graphicons, and the fixed content allowed us to focus on graphicon forms. However, while kaomoji meanings are rather general, the denotations of emojis and stickers are increasingly content specific; thus their usage might vary for different topics. We would not expect, for instance, to find as many graphicons on the theme of the Chinese New Year in comments on videos on other topics. More topics, and different platforms, should therefore be analyzed in order to increase the generalizability of our evolutionary findings.",

We therefore should be cautious in interpreting the statistics about graphicon usage in 2022, as they might not fully represent the graphicon usage of the year. Follow-up study with future data from BiliBili is needed to develop a fuller picture of graphicon evolution on the platform, particularly with regard to emojis and stickers.",
