This study examined social learning as an antecedent of engaging with misinformation online. Using data released by Twitter for academic research in 2018, Tweets that included URL news links of both known misinformation and reliable domains were analyzed. Lindström’s computational reinforcement learning model was adapted as an expression of social learning, where a Twitter user’s posting frequency of news links is dependent on the relative engagement they receive in consequence. The research found that those who shared misinformation were highly sensitive to social reward. Inflation of positive social feedback was associated with a decrease in posting latency, indicating that users that posted misinformation were strongly influenced by social learning. However, the posting frequency of authentic news sharers remained fixed, even after receiving an increase in relative and absolute engagement. The results identified social learning is a contributor to the spread of misinformation online. In addition, behavior driven by social validation suggests a positive correlation between posting frequency, gratification received from posting, and a growing mental health dependency on social media. Developing interventions for spreading misinformation online may profit by assessing which online environments amplify social learning, particularly the conditions under which misinformation proliferates.展开更多

How these two learning strategies differ ...There are mainly two different ways of learning for animals and humans: trying on yourself through interactions or imitating/copying others through communication/observation. How these two learning strategies differ and what roles they are playing in achieving coordination among individuals are two challenging problems for researchers from various disciplines. In multiagent systems, most existing work simply focuses on individual learning for achieving coordination among agents. The social learning perspective has been largely neglected. Against this background, this article contributes by proposing an integrated solution to decision making between social learning and individual learning in multiagent systems. Two integration modes have been proposed that enable agents to choose in between these two learning strategies, either in a t'Lxed or in an adaptive manner. Experimental evaluations have shown that these two kinds of leaning strategies have different roles in maintaining efficient coordination among agents. These differences can reveal some significant insights into the manipulation and control of agent behaviors in multiagent systems, and also shed light on understanding the social factors in shaping coordinated behaviors in humans and animals.展开更多

On one hand, in...While last decade has witnessed a rapid growth of digital economy, there is limited understanding in literature on whether the conventional wisdom on pricing strategy still holds for information goods. On one hand, information goods, similar to durable goods, are subject to value depreciation; on the other, they differ from traditional goods in negligible marginal cost and the sensitivity to social influences. This paper develops a two-period, game-theoretic model to investigate optimal pricing strategy of information goods. On one dimension, two different depreciation mechanisms (self- and time-depreciation) are considered; on the other, two prevalent pricing schemes (perpetual licensing and subscription-fee models) are studied. We obtain closed-form solutions in all scenarios. Our findings suggest that vendors of time-depreciation information goods should adopt subscription-fee model to attract early adopters and exploit social influences, while the vendors of self-depreciation information goods should strategically balance between depreciation and social influences. Interestingly, as social influences become strong enough, the difference between pricing schemes diminishes and the tradeoff between candidate strategies vanishes. We also extend the model to static pricing in which the vendor commits to future price. We discover that the superiority of subscription-fee model might be overturned under static pricing. Our results above also imply that building consumer feedback and interaction systems could be helpful for minimizing the potential loss of a suboptimal pricing scheme.展开更多

We propose a framework for fostering artificial soci- eties using social learning mechanisms and social control ap- proaches. We present the application of fostering artificial so- cieties in parallel emergency management systems. Then we discuss social learning mechanisms in artificial societies, in- cluding observational learning, reinforcement learning, imi- tation learning, and advice-based learning. Furthermore, we discuss social control approaches, including social norms, social policies, social reputations, social commitments, and sanctions.展开更多

Assigning proper tags to the visual content is key to the success of many applications such as image retrieval and content mining. Although recent years have witnessed many advances in image tagging, these methods have limitations when applied to high-quality and large-scale training data that are expensive to obtain. In this paper, we propose a novel semantic neighbor learning method based on user-contributed social image datasets that can be acquired from the Web's inexhaustible social image content. In contrast to existing image tagging approaches that rely on high-quality image-tag supervision, we acquire weak supervision of our neighbor learning method by progressive neighborhood retrieval from noisy and diverse user-contributed image collections. The retrieved neighbor images are not only visually alike and partially correlated but also semantically related. We offer a step-by-step and easy-to-use implementation for the proposed method. Extensive experimentation on several datasets demonstrates that the performance of the proposed method significantly outperforms others.展开更多

We evaluate consumers’ learning processes via the perusal of information in online communities using "pageview" data for multiple websites from a clickstream panel as indicators. We propose a bivariate Bayesian learning model combined with complementary purchase choices.The proposed model enables simpler estimation of parameters and allows to accommodate detailed information about interactions between social and personal learning processes. From the results, we find empirical evidence that companies’ traditional marketing actions have a greater impact on social learning than on regular personal learning during the pre-launch period. When consumers make purchase decisions, their social beliefs about product quality are weighed at least three times more heavily than their personal beliefs. Counterfactual simulations suggest that by optimizing marketing actions,firms can stimulate consumers’ learning and promote increased product engagement.展开更多

文摘Determining the role that social learning plays in construction behaviors,such as nest building or tool manufacture,could be improved if more experimental control could be gained over the exact public information that is provided by the demonstrator,to the observing individual.Using video playback allows the experimenter to choose what information is provided but will only be useful in determining the role of social learning if observers attend to,and learn from,videos in a manner that is similar to live demonstration.The goal of the current experiment was to test whether live-streamed video presentations of nest building by zebra finches Taeniopygia guttata would lead observers to copy the material choice demonstrated to them.Here,males that had not previously built a nest were given an initial preference test between materials of 2 colors.Those observers then watched live-stream footage of a familiar demonstrator building a nest with material of the color that the observer did not prefer.After this experience,observers were given the chance to build a nest with materials of the 2 colors.Although two-thirds of the observer males preferred material of the demonstrated color after viewing the demonstrator build a nest with material of that color more than they had previously,their preference for the demonstrated material was not as strong as that of observers that had viewed live demonstrator builders in a previous experiment.Our results suggest researchers should proceed with caution before using video demonstration in tests of social learning.

文摘While last decade has witnessed a rapid growth of digital economy, there is limited understanding in literature on whether the conventional wisdom on pricing strategy still holds for information goods. On one hand, information goods, similar to durable goods, are subject to value depreciation; on the other, they differ from traditional goods in negligible marginal cost and the sensitivity to social influences. This paper develops a two-period, game-theoretic model to investigate optimal pricing strategy of information goods. On one dimension, two different depreciation mechanisms (self- and time-depreciation) are considered; on the other, two prevalent pricing schemes (perpetual licensing and subscription-fee models) are studied. We obtain closed-form solutions in all scenarios. Our findings suggest that vendors of time-depreciation information goods should adopt subscription-fee model to attract early adopters and exploit social influences, while the vendors of self-depreciation information goods should strategically balance between depreciation and social influences. Interestingly, as social influences become strong enough, the difference between pricing schemes diminishes and the tradeoff between candidate strategies vanishes. We also extend the model to static pricing in which the vendor commits to future price. We discover that the superiority of subscription-fee model might be overturned under static pricing. Our results above also imply that building consumer feedback and interaction systems could be helpful for minimizing the potential loss of a suboptimal pricing scheme.
文摘How can we foster and grow artificial societies so as to cause social properties to emerge that are logical, consistent with real societies, and are expected by design- ers? We propose a framework for fostering artificial soci- eties using social learning mechanisms and social control ap- proaches. We present the application of fostering artificial so- cieties in parallel emergency management systems. Then we discuss social learning mechanisms in artificial societies, in- cluding observational learning, reinforcement learning, imi- tation learning, and advice-based learning. Furthermore, we discuss social control approaches, including social norms, social policies, social reputations, social commitments, and sanctions.

文摘The explosive increase in the number of images on the Internet has brought with it the great challenge of how to effectively index, retrieve, and organize these resources. Assigning proper tags to the visual content is key to the success of many applications such as image retrieval and content mining. Although recent years have witnessed many advances in image tagging, these methods have limitations when applied to high-quality and large-scale training data that are expensive to obtain. In this paper, we propose a novel semantic neighbor learning method based on user-contributed social image datasets that can be acquired from the Web's inexhaustible social image content. In contrast to existing image tagging approaches that rely on high-quality image-tag supervision, we acquire weak supervision of our neighbor learning method by progressive neighborhood retrieval from noisy and diverse user-contributed image collections. The retrieved neighbor images are not only visually alike and partially correlated but also semantically related. We offer a step-by-step and easy-to-use implementation for the proposed method. Extensive experimentation on several datasets demonstrates that the performance of the proposed method significantly outperforms others.
文摘Background and Objective:Social media(SoMe)has emerged as a tool in health professions education(HPE),particularly amidst the challenges posed by the coronavirus disease 2019(COVID-19)pandemic.Despite the academia’s initial skepticism SoMe has been gaining traction in supporting learning communities,and offering opportunities for innovation in HPE.Our study aims to explore the integration of SoMe in HPE.Four key components were outlined as necessary for a successful integration,and include designing learning experiences,defining educator roles,selecting appropriate platforms,and establishing educational objectives.Methods:This article stemmed from the online Teaching Skills Series module on SoMe in education from the Ophthalmology Foundation,and drew upon evidence supporting learning theories relevant to SoMe integration and models of education.Additionally,we conducted a literature review considering Englishlanguage articles on the application of SoMe in ophthalmology from PubMed over the past decade.Key Content and Findings:Early adopters of SoMe platforms in HPE have leveraged these tools to enhance learning experiences through interaction,dialogue,content sharing,and active learning strategies.By integrating SoMe into educational programs,both online and in-person,educators can overcome time and geographical constraints,fostering more diverse and inclusive learning communities.Careful consideration is,however,necessary to address potential limitations within HPE.Conclusions:This article lays groundwork for expanding SoMe integration in HPE design,emphasizing the supportive scaffold of various learning theories,and the need of furthering robust research on examining its advantages over traditional educational formats.Our literature review underscores an ongoing multifaceted,random application of SoMe platforms in ophthalmology education.We advocate for an effective incorporation of SoMe in HPE education,with the need to comply with good educational practice.
文摘This research examines the micro-level correlation between traditional marketing actions(TV ads and public relations) and pre-release consumers’ social learning about videogame consoles(Wii and PS3, launched in 2006). We evaluate consumers’ learning processes via the perusal of information in online communities using "pageview" data for multiple websites from a clickstream panel as indicators. We propose a bivariate Bayesian learning model combined with complementary purchase choices.The proposed model enables simpler estimation of parameters and allows to accommodate detailed information about interactions between social and personal learning processes. From the results, we find empirical evidence that companies’ traditional marketing actions have a greater impact on social learning than on regular personal learning during the pre-launch period. When consumers make purchase decisions, their social beliefs about product quality are weighed at least three times more heavily than their personal beliefs. Counterfactual simulations suggest that by optimizing marketing actions,firms can stimulate consumers’ learning and promote increased product engagement.
