Cutting-edge computational tools like artificial intelligence, data scraping, and online experiments are leading to new discoveries about the human mind. However, these new methods can be intimidating. This textbook demonstrates how Big Data is transforming the field of psychology, in an approachable and engaging way that is geared toward undergraduate students without any computational training. Each chapter covers a hot topic, such as social networks, smart devices, mobile apps, and computational linguistics. Students are introduced to the types of Big Data one can collect, the methods for analyzing such data, and the psychological theories we can address. Each chapter also includes discussion of real-world applications and ethical issues. Supplementary resources include an instructor manual with assignment questions and sample answers, figures and tables, and varied resources for students such as interactive class exercises, experiment demos, articles, and tools.
This study investigates the integration of literal completions of idiomatic multiword expressions (MWEs) into two linguistic contexts: one promoting a literal interpretation and the other a figurative one, requiring reinterpretation to align with figurative bias. Sixteen Italian idioms were distributed in two groups by their Potential Idiomatic Ambiguity (PIA) score, an index of literal plausibility, decomposability and transparency. Using experimental dialogues, the study tested whether high-PIA idioms receive higher acceptability ratings across both contexts than low-PIA idioms. Eighty-four Italian-speaking participants rated idiom literal completions within literal and figurative contexts. Results show that literal completions of high-PIA idioms integrate better across contexts, while those of low-PIA idioms receive lower ratings and have longer combined reading and rating times. This supports hybrid models of idiom processing, emphasizing the role of idiomatic features and context in balancing figurative and compositional interpretations. This study also marks an initial effort to experimentally trace systematicity within idiomatic wordplay, challenging the idea that it lacks relevance for linguistic research while outlining limitations and directions for future work.
In the book’s first chapter, we looked at how technological change created conditions for the emergence and dominance of a specific form of innovation management. Coming full circle, this chapter asks how further technological change might challenge that form. We begin with technological change that is already here and that has begun to impact how innovation is managed. In Baldwin and von Hippel’s analysis, innovations in communication technologies and design tools are given credit for the expanding role of nonfirms in innovation, effecting shifts in the locus of innovation in society away from producer-firms toward users and peer-to-peer collaborations. In that view, firms might be poised to play a much smaller role in the innovation process of the future. Examining some of the same technologies, Altman et al. do not see the imminent end of firm-centric innovation. Instead, they propose that innovation management will evolve, that firms will take on new forms of collaboration and more porous boundaries to fully benefit from the possibilities of technological change. To close, we turn again to the question of how artificial intelligence might play into the further transformation of organizations. Cockburn et al.’s analysis asks whether artificial intelligence might be a method in the method of invention and what that might mean for the future of innovation and economic development.
Crowdsourcing platforms—such as Vivino—that aggregate the opinions of large numbers of amateur wine reviewers represent a new source of information on the wine market. We assess the validity of aggregated Vivino ratings based on two criteria: correlation with professional critics’ ratings and sensitivity to weather conditions affecting the quality of grapes. We construct a large, novel dataset consisting of Vivino ratings for a portfolio of red wines from Bordeaux, review scores from professional critics, and weather data from a local weather station. Vivino ratings correlate substantially with those of professional critics, but these correlations are smaller than those among professional critics. This difference can be partly attributed to differences in scope: Whereas amateurs focus on immediate pleasure, professionals gauge the wine’s potential once it has matured. Moreover, both crowdsourced and professional ratings respond to weather conditions in line with what viticulture literature has identified as ideal, but also hint to detrimental effects of global warming on wine quality. In sum, our results demonstrate that crowdsourced ratings are a valid source of information and can generate valuable insights for both consumers and producers.
Brain areas implicated in semantic memory can be damaged in patients with epilepsy (PWE). However, it is challenging to delineate semantic processing deficits from acoustic, linguistic, and other verbal aspects in current neuropsychological assessments. We developed a new Visual-based Semantic Association Task (ViSAT) to evaluate nonverbal semantic processing in PWE.
Method:
The ViSAT was adapted from similar predecessors (Pyramids & Palm Trees test, PPT; Camels & Cactus Test, CCT) comprised of 100 unique trials using real-life color pictures that avoid demographic, cultural, and other potential confounds. We obtained performance data from 23 PWE participants and 24 control participants (Control), along with crowdsourced normative data from 54 Amazon Mechanical Turk (Mturk) workers.
Results:
ViSAT reached a consensus >90% in 91.3% of trials compared to 83.6% in PPT and 82.9% in CCT. A deep learning model demonstrated that visual features of the stimulus images (color, shape; i.e., non-semantic) did not influence top answer choices (p = 0.577). The PWE group had lower accuracy than the Control group (p = 0.019). PWE had longer response times than the Control group in general and this was augmented for the semantic processing (trial answer) stage (both p < 0.001).
Conclusions:
This study demonstrated performance impairments in PWE that may reflect dysfunction of nonverbal semantic memory circuits, such as seizure onset zones overlapping with key semantic regions (e.g., anterior temporal lobe). The ViSAT paradigm avoids confounds, is repeatable/longitudinal, captures behavioral data, and is open-source, thus we propose it as a strong alternative for clinical and research assessment of nonverbal semantic memory.
This chapter looks beyond the temporal scope of the rest of book to the legacy of the OED’s empirical principles for contemporary dictionaries. The chapter argues that there are limitations inherent in any lexicographical model whose aim is to document a language as it is commonly and widely used. Though this ‘majority rule’ approach may seem democratic, it cannot help but marginalize people whose practices or identities—and the language by which they express them—diverge from dominant norms. While digital advances have enabled new ways of making dictionaries, from corpus-building to online crowdsourcing, these have not allowed lexicographers to evade the ideological pitfalls that surround the documentation of ‘minority usage’, whether present or past. The chapter closes with a reflection on the future of historical research into language and sexuality, both within the dictionary and beyond it.
Recent advances in machine learning have enabled computers to converse with humans meaningfully. In this study, we propose using this technology to facilitate design conversations in large-scale urban development projects by creating chatbot systems that can automate and streamline information exchange between stakeholders and designers. To this end, we developed and evaluated a proof-of-concept chatbot system that can perform design conversations on a specific construction project and convert those conversations into a list of requirements. Next, in an experiment with 56 participants, we compared the chatbot system to a regular online survey, focusing on user satisfaction and the quality and quantity of collected information. The results revealed that, with regard to user satisfaction, the participants preferred the chatbot experience to a regular survey. However, we found that chatbot conversations produced more data than the survey, with a similar rate of novel ideas but fewer themes. Our findings provide robust evidence that chatbots can be effectively used for design discussions in large-scale design projects and offer a user-friendly experience that can help to engage people in the design process. Based on this evidence, by providing a space for meaningful conversations between stakeholders and expanding the reach of design projects, the use of chatbot systems in interactive design systems can potentially improve design processes and their outcomes.
Researchers have encountered many issues while studying rare illnesses such as lack of information, limited sample sizes, difficulty in diagnosis, and more. However, perhaps the biggest challenge is to recruit a large enough sample size for clinical studies; at the same time, obtaining chronological data for these patients is even more difficult. This has urged us to implement a decentralized crowdsourcing medical data sharing platform to obtain chronological rare data for certain diseases, providing both patients and other stakeholders an easier and more secure way of trading medical data by utilizing blockchain technology. This facilitates the obtention of the most elusive types of health data by dynamically allocating extra financial incentives depending on data scarcity. We also provide a novel framework for medical data cross-validation where the system checks the volunteer reviewer count. The review score depends on the count, and the more the reviewers, the bigger the final score. We also explain how differential privacy is used to protect the privacy of individual medical data while enabling data monetization.
Oxymorons combine two opposite terms in a paradoxical manner. They are closely intertwined with antonymy, since the union of antonymous items creates the paradoxical effect of the oxymoron and generates a new meaning. Compared to other forms of figurative language, oxymorons are largely underinvestigated. We explored what makes good oxymorons through a crowdsourcing task in which we asked participants to judge the acceptability, comprehensibility, effectiveness/aptness, commonness, pleasantness, and humoristic connotation of Italian adjective–noun oxymorons. We hypothesized that oxymorons featuring morphologically related antonyms (felice infelicità ‘happy unhappiness’) may be perceived to be better than oxymorons featuring morphologically unrelated antonyms (felice tristezza ‘happy sadness’) and that oxymorons constructed by complementaries (esatta inesattezza ‘exact inexactness’) may be perceived to be better than oxymorons constructed by contraries (bella bruttezza ‘beautiful ugliness’). The results confirmed only partially our hypotheses: oxymorons with complementaries were perceived as more acceptable, comprehensible, effective/apt, common, whereas no strong trend was found for the other two dimensions. Surprisingly, our analyses revealed that oxymoronic constructions containing morphologically unrelated words were perceived as more acceptable, comprehensible, effective/apt, common, pleasant, contradicting our initial expectations.
New technologies hold great promises of making crisis response better. These technologies may improve information positions and enable faster communication as well as produce more rapid and targeted responses in crises. As such, technological progress boosts effectiveness and efficiency, while reducing risks to frontline responders. Still, the reality does not always match these great expectations due to technical failures and implementation difficulties as well as persistent social problems that cannot be resolved by new tools or systems. There are often even undesirable side effects. The dilemma for frontline responders revolves around finding the right attitude toward new technologies. Technological progress is a historical inevitability, but new innovations should only be adopted if these match a recognized problem in the response and not just for their own sake. There are guiding principles, based on earlier experiences, that offer useful insights in how to best incorporate modern tools and systems. This requires a prudent approach that considers new technology with a mix of hesitation and curiosity.
Le français est une langue parlée par plusieurs centaines de millions de locuteurs en Europe, en Afrique et en Amérique. Une telle dispersion favorise la variation, mais de grands corpus unifiés permettant de rendre compte de cette variation à l’échelle mondiale restent rares, et dans tous les cas nécessitent des efforts financiers et humains non négligeables, à l’instar du projet de Phonologie du Français Contemporain. Dans cet article, nous présentons une alternative possible : les données participatives. Pour ce faire, nous présentons Lingua Libre, la médiathèque linguistique participative de Wikimédia France, et l’utilisons pour décrire la variation sur une opposition phonémique entre deux voyelles ouvertes, /a/ et /ɑ/, dans de nombreuses variétés de français. Les données de 38 locuteurs provenant de 26 points d’enquête sont traitées automatiquement et comparées aux mesures présentées dans la littérature passée. Les résultats montrent que la plateforme a le potentiel de donner des résultats conformes à ceux des études de terrain professionnelles. L’article conclut sur les avantages et les limites de la plateforme, tout en proposant des pistes d’amélioration.
Although the individual has been the focus of most research into judgment and decision-making (JDM), important decisions in the real world are often made collectively rather than individually, a tendency that has increased in recent times with the opportunities for easy information exchange through the Internet. From this perspective, JDM research that factors in this social context has increased generalizability and mundane realism relative to that which ignores it. We delineate a problem-space for research within which we locate protocols that are used to study or support collective JDM, identify a common research question posed by all of these protocols—‘What are the factors leading to opinion change for the better (‘virtuous opinion change’) in individual JDM agents?’—and propose a modeling approach and research paradigm using structured groups (i.e., groups with some constraints on their interaction), for answering this question. This paradigm, based on that used in studies of judge-adviser systems, avoids the need for real interacting groups and their attendant logistical problems, lack of power, and poor experimental control. We report an experiment using our paradigm on the effects of group size and opinion diversity on judgmental forecasting performance to illustrate our approach. The study found a U-shaped effect of group size on the probability of opinion change, but no effect on the amount of virtuous opinion change. Implications of our approach for development of more externally valid empirical studies and theories of JDM, and for the design of structured-group techniques to support collective JDM, are discussed.
The availability of digital data in the fourth industrial revolution brings different trends with new opportunities and challenges for the engineering design community. As an opportunity, these trends would impact engineering design. However, the challenge is finding applications for these trends in engineering design. Crowdsourcing is one of the trends inspired by digital data. It is outsourcing an individually performed task to be mass-performed. This paper explores the application of crowdsourcing in identifying engineering design problems. Identifying an engineering design problem is an aspect of engineering design considered challenging but necessary for inventions. Secondary data from 63 invention-related cases and an interview with a renowned UK inventor are presented. The data contains scenarios on how the engineering design problems solved to qualify for a UK patent grant or application are identified. Lessons from the case studies are presented and discussed, especially regarding crowdsourcing engineering design problems. These seem to be promising ways of supporting the identification of new engineering design problems with inventive benefits once solved.
We examined the trade-off between the cost of response redundancy and the gain in output quality on the popular crowdsourcing platform Mechanical Turk, as a partial replication of Kosinski et al. (2012) who demonstrated a significant improvement in performance by aggregating multiple responses through majority vote. We submitted single items from a validated intelligence test as Human Intelligence Tasks (HITs) and aggregated the responses from “virtual groups” consisting of 1 to 24 workers. While the original study relied on resampling from a relatively small number of responses across a range of experimental conditions, we randomly and independently sampled from a large number of HITs, focusing only on the main effect of group size. We found that – on average – a group of six MTurkers has a collective IQ one standard deviation above the mean for the general population, thus demonstrating a “wisdom of the crowd” effect. The relationship between group size and collective IQ was characterised by diminishing returns, suggesting moderately sized groups provide the best return on investment. We also analysed performance of a smaller subset of workers who had each completed all 60 test items, allowing for a direct comparison between a group’s collective IQ and the individual IQ of its members. This demonstrated that randomly selected groups collectively equalled the performance of the best-performing individual within the group. Our findings support the idea that substantial intellectual capacity can be gained through crowdsourcing, contingent on moderate redundancy built into the task request.
Cities did not somehow emerge fully formed; they developed gradually – usually in oscillating, uneven lurches of development over time. Exacerbated by climate change, extreme weather events and sea levels are rising rapidly. This poses a significant, immediate threat to coastal or riverine cities and the priceless historic resources that make them unique. As protecting cultural heritage becomes a global priority, identifying effective strategies that governments can use to identify, manage, and protect historic resources is critical. This chapter is divided into two sections. The first part discusses some of the public health benefits that historic resources bring to urban areas and how cultural heritage increases urban resilience. The second section analyzes two important technological strategies that governments at all levels should have (or develop) to fulfill their legal obligations to protect cultural heritage by engaging the public more broadly in preservation initiatives.
As COVID-19 was declared a health emergency in March 2020, there was immense demand for information about the novel pathogen. This paper examines the clinician-reported impact of Project ECHO COVID-19 Clinical Rounds on clinician learning. Primary sources of study data were Continuing Medical Education (CME) Surveys for each session from the dates of March 24, 2020 to July 30, 2020 and impact surveys conducted in November 2020, which sought to understand participants’ overall assessment of sessions. Quantitative analyses included descriptive statistics and Mann-Whitney testing. Qualitative data were analyzed through inductive thematic analysis. Clinicians rated their knowledge after each session as significantly higher than before that session. 75.8% of clinicians reported they would ‘definitely’ or ‘probably’ use content gleaned from each attended session and clinicians reported specific clinical and operational changes made as a direct result of sessions. 94.6% of respondents reported that COVID-19 Clinical Rounds helped them provide better care to patients. 89% of respondents indicated they ‘strongly agree’ that they would join ECHO calls again.COVID-19 Clinical Rounds offers a promising model for the establishment of dynamic peer-to-peer tele-mentoring communities for low or no-notice response where scientifically tested or clinically verified practice evidence is limited.
The Portable Antiquities of the Netherlands (PAN) is an online system aimed at recording and documenting archaeological finds by the public. Since PAN launched in 2016, it has become an important data contributor to Dutch archaeology, amassing over 100,000 recorded finds. These data, mostly the result of metal detection, enable scholars to gain new insights and policy makers to make more informed decisions. This review describes the context in which PAN was established, along with its current structure and scope, before looking at its different components, including the underlying database and linked data reference collection. In a final section, the article briefly addresses some common issues inherent to public reporting programs and how PAN approaches these issues.
The international community is too often focused on responding to the latest cyber attack instead of addressing the reality of pervasive and persistent cyber conflict. From ransomware against the city government of Baltimore to state-sponsored campaigns targeting electrical grids in Ukraine and the United States, we seem to have relatively little bandwidth left over to ask what we can hope for in terms of “peace” on the Internet, and how to get there. It’s also important to identify the long-term implications for such pervasive cyber insecurity across the public and private sectors, and how they can be curtailed. This edited volume analyzes the history and evolution of cyber peace and reviews recent international efforts aimed at promoting it, providing recommendations for students, practitioners, and policymakers seeking an understanding of the complexity of international law and international relations involved in cyber peace. This title is also available as Open Access on Cambridge Core.
The last Chapter explores crowdfunding, a method of raising money from a large number of people via the internet. Crowdfunding is a new financial tool that allows ordinary investors to get in on the ground floor of startup investing. Crowdfunding solves several problems that are common in financial markets by capitalizing on the wisdom of the crowd by sharing information freely and leveraging online reputation. Equity crowdfunding is now a legitimate means to raise capital under the JOBS Act. However, this Chapter discusses how excessive regulations, such as the income threshold requirement, the inability to resell illiquid securities, and unrealistically low funding limits, hamper the most promising features of equity crowdfunding. Therefore, regulators must proactively design legislation that harnesses the benefits while mitigating costs, and further promote the attractiveness of open, public, and non-secretive markets.
This chapter describes methods for executing the designed experiment and recording the response variables. The ethical implications of the experiment have to be considered before starting data collection, with the aim to minimize harmful impacts. Various data sources and data collection methods are available: archival data sources, passive data collection, active data collection with methods to influence input variables, data collection from mobile apps, and data collection via crowdsourcing. The chapter also describes methods to store the collected data.
