Digitally enabled means for judgment aggregation have renewed interest in “wisdom of the crowd” effects and kick-started collective intelligence design as an emerging field in the cognitive and computational sciences. A keenly debated question here is whether social influence helps or hinders collective accuracy on estimation tasks, with recent results on the role of network structure hinting at a reconciliation of seemingly contradictory past results. Yet, despite a growing body of literature linking social network structure and collective accuracy, strategies for exploiting network structure to harness crowd wisdom are underexplored. We introduce one such strategy: rewiring algorithms that dynamically manipulate the structure of communicating social networks. Through agent-based simulations and an online multiplayer experiment, we provide a proof of concept showing how rewiring algorithms can increase the accuracy of collective estimations—even in the absence of knowledge of the ground truth. However, we also find that the algorithms’ effects are contingent on the distribution of estimates initially held by individuals before communication occurs. •Human-centered computing → Collaborative and social computing• Applied computing → Psychology.
数字化的判断汇总手段重新激发了人们对 "群体智慧 "效应的兴趣,并使集体智能设计成为认知科学和计算科学的一个新兴领域。其中一个争论激烈的问题是,社会影响是帮助还是阻碍了估算任务的集体准确性,而最近关于网络结构作用的研究结果则暗示着可以调和过去看似矛盾的结果。然而,尽管越来越多的文献将社会网络结构与集体准确性联系在一起,但利用网络结构来发挥群众智慧的策略却未得到充分探索。我们介绍了一种这样的策略:动态操纵交流社交网络结构的重新布线算法。通过基于代理的模拟和在线多人游戏实验,我们提供了一个概念证明,展示了重新布线算法如何提高集体估计的准确性--即使是在不了解基本事实的情况下。不过,我们也发现,算法的效果取决于通信发生前个人最初所持估计的分布情况。-以人为本的计算 → 协作和社会计算 - 应用计算 → 心理学。

Designing interaction techniques for end-users often involves exploring vast design spaces while balancing many objectives. Bayesian optimization offers a principled human-in-the-loop method for selecting designs for evaluation to efficiently explore such design spaces. To date, the application of Bayesian optimization in a human-in-the-loop setting has largely been restricted to optimization, or customization, of interaction techniques for individual user needs. In practice, interaction techniques are typically designed for a target population or group of users, with the goal is to produce a design that works well for most users. To accommodate this common use case in interaction technique design, we introduce two practical approaches that facilitate multi-objective Bayesian optimization at the group level. Specifically, our approaches streamline the process of (1) deriving designs suitable for a group of users from data collected in individual user evaluations; and (2) deriving an initialization from group data to improve the efficiency of design optimization for new users. We demonstrate the advantages of these practical approaches in two multi-phase user studies involving the design of non-trivial interaction techniques.
为最终用户设计交互技术往往需要探索广阔的设计空间,同时兼顾多个目标。贝叶斯优化法提供了一种原则性的人在环方法,用于选择设计进行评估,从而有效地探索此类设计空间。迄今为止,贝叶斯优化法在 "人在回路 "环境中的应用主要局限于优化或定制交互技术,以满足用户的个性化需求。在实践中,交互技术通常是为目标人群或用户群设计的,目标是设计出适合大多数用户的交互技术。为了适应交互技术设计中的这种常见情况,我们引入了两种实用方法,以促进群体层面的多目标贝叶斯优化。具体来说,我们的方法简化了以下过程:(1) 从单个用户评估中收集的数据中推导出适合一组用户的设计;(2) 从群体数据中推导出初始化,以提高针对新用户的设计优化效率。我们在两项多阶段用户研究中展示了这些实用方法的优势,这些研究涉及到非简单交互技术的设计。

Theoretical constructs, such as the information gap theory and compression progress theory, seek to explain how humans practice curiosity. According to the former, curiosity is the drive to acquire information missing from our understanding of the world. According to the latter, curiosity is the drive to construct parsimonious mental world models. To complement the densification and simplification processes inherent to these frameworks, we propose the conformational change theory, wherein we posit that curiosity builds mental models with marked conceptual flexibility. We formalize curiosity as a knowledge-network-building process to investigate each theoretical account for individuals and collectives. In knowledge networks, gaps can be identified as topological cavities, compression progress can be quantified using network compressibility, and flexibility can be measured as the number of conformational degrees of freedom. We find that curiosity fills gaps and constructs increasingly compressible and flexible knowledge networks. Across individuals and collectives, we determine the contexts in which each account is explanatory, clarifying their complementary and distinct contributions. Our findings offer a novel networks-based perspective that harmonizes with (and compels an expansion of) the traditional taxonomy of curiosity.
理论建构,如信息缺口理论和压缩进步理论,试图解释人类如何实践好奇心。根据前者的观点,好奇心是获取我们对世界的理解中缺失的信息的动力。根据后者的说法,好奇心是构建节俭的心理世界模型的动力。为了补充这些框架固有的致密化和简化过程,我们提出了构象变化理论,其中我们假设好奇心建立了具有显著概念灵活性的心理模型。我们将好奇心形式化为一种知识网络构建过程,以调查个人和集体的每种理论解释。在知识网络中,间隙可以识别为拓扑空腔,压缩进度可以使用网络可压缩性来量化,而灵活性可以通过构象自由度的数量来衡量。我们发现好奇心填补了空白,并构建了越来越可压缩和灵活的知识网络。在个人和集体中,我们确定了每种解释的背景,阐明了它们的互补和独特贡献。我们的发现提供了一种新颖的基于网络的视角,与传统的好奇心分类相协调(并迫使其扩展)。

Intelligence Everywhere is predicated on the seamless integration of INTERNET of Things (IoT) networks transporting a vast amount of data streams through many computing resources across an edge-to-cloud continuum, relying on the orchestration of distributed machine learning models. The result is an interconnected and collective intelligent ecosystem where devices, systems, services, and users work together to support IoT applications. This paper discusses the state-of-the-art research and the principles of the Intelligence Everywhere framework for enhancing IoT applications in vertical sectors such as Digital Health, Infrastructure, and Transportation/Mobility in the context of intelligent society (Society 5.0). It also introduces a novel perspective for the development of horizontal IoT applications, capable of running across various IoT networks while fostering collective intelligence across diverse sectors. Finally, this paper provides comprehensive insights into the challenges and opportunities for harnessing collective knowledge from real-time insights, leading to optimised processes and better overall collaboration across different IoT sectors.
智能无处不在是基于物联网(IoT)网络的无缝集成,通过边缘到云连续体的许多计算资源传输大量数据流,依赖于分布式机器学习模型的编排。其结果是一个相互关联的集体智能生态系统,其中设备,系统,服务和用户协同工作以支持物联网应用。本文讨论了智能无处不在框架的最新研究和原则,以增强智能社会(社会5.0)背景下数字健康、基础设施和交通/移动等垂直领域的物联网应用。它还为横向物联网应用的开发引入了一个新的视角,能够跨各种物联网网络运行,同时促进跨不同部门的集体智慧。最后,本文提供了对利用实时洞察中的集体知识的挑战和机遇的全面见解,从而优化流程并在不同物联网部门之间实现更好的整体协作。

Developing system understanding and testing interventions are critical steps to addressing wicked problems. Fuzzy cognitive mapping (FCM) can be a useful participatory modeling tool that enables aggregation of individual perspectives to build system models that represent groups’ collective intelligence (CI). However, current FCM aggregation methodologies for creating CI models have rarely been tested and compared. We conducted 51 FCM interviews with local experts in the Flint, MI food system to map their mental models about how different food system sectors influenced desirable outcomes. Using four differing aggregation techniques, based on experts’ identity diversity and cognitive diversity, we generated four CI models. The models were compared based on their similarity to real-world complex systems using performance metrics like network structure, micro-motifs, cognitive distance, and scenario outcomes. We found that using cognitive diversity to group individuals was better suited for modeling systems with diverse holders of knowledge.
发展系统理解和测试干预措施是解决棘手问题的关键步骤。模糊认知映射(FCM)是一种有用的参与式建模工具,它可以聚合个人视角来构建代表群体集体智慧(CI)的系统模型。然而,目前用于创建CI模型的FCM聚合方法很少被测试和比较。我们对密歇根州弗林特食品系统的当地专家进行了51次FCM访谈,以绘制他们关于不同食品系统部门如何影响理想结果的心理模型。基于专家的身份多样性和认知多样性,采用四种不同的聚合技术,生成了四种CI模型。通过网络结构、微主题、认知距离和场景结果等性能指标,对模型与现实世界复杂系统的相似性进行了比较。我们发现,使用认知多样性对个体进行分组更适合于具有不同知识持有者的系统建模。

Semantic computing with IEML 基于IEML的语义计算
Pub Date : 2023-10-01 DOI: 10.1177/26339137231207634
Pierre Lévy
This paper presents IEML, Information Economy MetaLanguage, a constructed language with the same expressive power as a natural language and with computable semantics. Distinguished from pragmatic and referential semantics, linguistic semantics have not yet been completely formalized. Only its syntagmatic dimension has been mathematized in the form of regular languages. Its paradigmatic dimension remained to be formalized. In order to complete the mathematizing of language, including its paradigmatic dimension, I have coded linguistic semantics with IEML. This article introduces its 3000-word dictionary, its formal grammar, and its integrated tools for building semantic graphs. For the future, IEML could become a vector for a fluid calculation and communication of meaning—semantic interoperability—capable of de-compartmentalizing the digital memory, and of advancing the progress of collective intelligence, artificial intelligence, and digital humanities. I conclude by indicating some research directions.
信息经济元语言(IEML)是一种具有与自然语言相同的表达能力和可计算语义的构造语言。与语用语义学和指称语义学不同,语言语义学尚未完全形式化。只有它的组合维度以规则语言的形式被数学化了。它的范例维度仍有待正式确定。为了完成语言的数学化,包括它的范式维度,我用IEML编码了语言语义。本文介绍了它的3000字字典、形式语法和用于构建语义图的集成工具。在未来,IEML可能会成为一种流体计算和意义交流的载体——语义互操作性——能够去划分数字记忆,并推动集体智能、人工智能和数字人文学科的进步。最后,我指出了一些研究方向。

Shared language in the team network-performance association: Reconciling conflicting views of the network centralization effect on team performance 团队网络绩效关联中的共享语言:协调网络集中化对团队绩效影响的不同观点

We reconcile two conflicting views of the network centralization effect on team performance. In one view, a centralized network is problematic because it limits knowledge transfer, making it harder for team members to discover productive combinations of their know-how and expertise. In the alternative view, the limits on knowledge transfer encourage search and experimentation, leading to the discovery of more valuable ideas. We maintain the two sides are not opposed but reflect two distinct ways centralization can affect a team’s shared problem-solving framework. The shared framework in our research is a shared language. We contend that team network centralization affects both how quickly a shared language emerges and the performance implications of the shared language that develops. We analyze the performance of 77 teams working to identify abstract symbols for 15 trials. Teams work under network conditions that vary with respect to centralization. Results indicate that centralized teams take longer to develop a shared language, but centralized teams also create a shared language that is more beneficial for performance. The findings also indicate that the highest performing teams are assigned to networks that combine elements of a centralized and a decentralized network.
我们调和了网络集中化对团队绩效影响的两种相互矛盾的观点。一种观点认为,集中式网络是有问题的,因为它限制了知识转移,使团队成员更难发现他们的知识和专业知识的有效组合。在另一种观点中,对知识转移的限制鼓励了搜索和实验,从而导致发现更有价值的想法。我们认为,这两方面并不对立,而是反映了集中化影响团队共同解决问题框架的两种截然不同的方式。我们研究中的共享框架是一种共享语言。我们认为,团队网络集中化既会影响共享语言出现的速度,也会影响开发的共享语言的性能。我们分析了77个团队在15次试验中识别抽象符号的表现。团队在网络条件下工作,这些网络条件随集中化程度的不同而变化。结果表明,集中式团队需要更长的时间来开发共享语言,但是集中式团队也可以创建更有利于性能的共享语言。研究结果还表明,表现最好的团队被分配到集中和分散网络元素相结合的网络中。

Crowd science and science skepticism 大众科学和科学怀疑主义
Pub Date : 2023-04-01 DOI: 10.1177/26339137231176480
O. A. Acar
Science skepticism is widespread and on the rise. It is a strong threat to public well-being and global sustainability. In this paper, I argue that crowd science is a promising and underutilized tool to fight this threat. Drawing on recent behavioral research in marketing, I identify several positive psychological consequences of crowd science initiatives—both for the participants and observers of these initiatives—which could in turn promote stronger trust in science.
科学怀疑主义很普遍,而且还在上升。这是对公众福祉和全球可持续性的严重威胁。在本文中,我认为群体科学是一种很有前途但未被充分利用的对抗这种威胁的工具。根据最近的市场营销行为研究,我确定了群体科学倡议的几个积极的心理后果——对这些倡议的参与者和观察者都是如此——这反过来又可以促进对科学的更强信任。

An analogy is drawn between the study of human behavior and the study of plutonium to demonstrate that soft and hard sciences are more similar than different, making the distinction moot and unproductive. The studies of human behavior and plutonium follow a common scientific research cycle that aligns with Thomas Kuhn’s views of scientific change. This common research cycle provides evidence that the thought processes and methodologies required for success are congruent in the soft and hard sciences. The primary implication from this analogy is that scientists in all disciplines should eradicate the distinction between soft and hard sciences. Focusing on similarities rather than differences among researchers from different disciplines is necessary to enhance collective intelligence and the type of transdisciplinary collaboration required to tackle difficult sociotechnical problems. CCS Concepts: • Social and professional topics • User characteristics • Cultural characteristics.
对人类行为的研究和对钚的研究进行了类比,以证明软科学和硬科学的相似之处多于不同之处,这使得两者的区别毫无意义,也没有任何意义。对人类行为和钚的研究遵循了一个常见的科学研究周期,这与托马斯·库恩(Thomas Kuhn)关于科学变化的观点一致。这个共同的研究周期提供了证据,证明成功所需的思维过程和方法在软科学和硬科学中是一致的。这个类比的主要含义是,所有学科的科学家都应该消除软科学和硬科学之间的区别。关注来自不同学科的研究人员之间的相似性而不是差异性,对于提高集体智慧和解决困难的社会技术问题所需的跨学科合作类型是必要的。CCS概念:•社会和专业主题•用户特征•文化特征。
