  • I think there is a difference between exploring, a deliberate exposing to things unknown and serendipity, an accidental encounter with the unknown. In the first case, the mind is prepared for the situation. In the second, the mind needs to be receptive to the serendipity. I think that design may matter a lot here. A serendipitous result low on a list may not have the same impact as a point on a map or a line in a story.
  • Oxford English dictionary’’s definitions of:
    • serendipity: “the faculty of making happy and unexpected discoveries by accident”.  
    • explore:  An act of exploring an unfamiliar place; an exploration, an excursion. 
    • discoverTo disclose, reveal, etc., to others or (later) oneself; to find out. 
    • sagacity: Acuteness of mental discernment; aptitude for investigation or discovery; keenness and soundness of judgement in the estimation of persons and conditions, and in the adaptation of means to ends; penetration, shrewdness.
    • synchronicity: the phenomenon of events which coincide in time and appear meaningfully related but have no discoverable causal connection.

    • The bohemian bookshelf: supporting serendipitous book discoveries through information visualization
      • A ThudtU HinrichsS Carpendale
      • Serendipity, a trigger of exciting discoveries when we least expect it, is currently being discussed as an often neglected but still important factor in information seeking processes, research, and ideation. In this paper we explore serendipity as an information visualization goal. In particular, we introduce the Bohemian Bookshelf visualization that aims to support serendipitous exploration of digital book collections. The Bohemian Bookshelf consists of five interlinked visualizations, each representing a unique (over)view of the collection. It facilitates serendipitous discoveries by (1) offering multiple access points by providing visualizations of different perspectives on the book collection, (2) enticing curiosity through abstract, metaphorical, and visually distinct representations of the collection, (3) highlighting alternate adjacencies between books, (4) providing multiple pathways for exploring the data collection in a flexible way, (5) supporting immediate previews of books, and (6) enabling a playful approach to information exploration. Our design goals and their exploration through the Bohemian Bookshelf visualization opens up a discussion on how to promote serendipity through information visualization.
      • six design goals that we have derived for promoting serendipitous discoveries through information visualization.
      • Austin coined the term altamirage that describes serendipitous discoveries as a result of chance paired with individual traits of the exploring person [2, 29].
      • This is closely related to the notion of synchronicity where related ideas may manifest as simultaneous occurrences that seem acausal but still meaningful [29].
      • The prevalence of these ideas of chance, fortuity, and coincidence in the discussion around serendipity has led to a tendency to trivialize this complex concept by assuming that serendipity can be supported simply through the introduction of randomness.
      • The design of the Bohemian Bookshelf offers multiple pathways through the book collection by (1) providing multiple interactive overviews of the book collection that can guide the information seeker into different and interesting directions, (2) the presentation of adjacent data that can act as visual signposts providing alternatives for the viewer to move through the dataset by following up on related books, and (3) emphasizing cross visualization attributes by mutual highlighting as in coordinated views [3, 7]
      • multiple pathways through the book collection that can provide guidance in a serendipitous way. The visual overviews can provide one way of exploring books. For instance, visitors can systematically browse through all books of their favourite colour and, in this way, possibly encounter books that are of interest to them but that they did not think of to search for directly. Furthermore, emphasizing adjacent books can be considered as visual signposts. For instance, following up on highlighted books in the Book Pile is likely to rapidly guide people serendipitously to different topical areas of the book collection. As a third approach to multiple pathways, all visualizations of the Bohemian Bookshelf are interlinked with each other. Therefore, every selection of a book in one visualization can be considered a cross road to the other visualizations that highlight this selection as well in their particular context.
      • We deliberately designed the Bohemian Bookshelf to provide multiple overviews of the entire book collection to provide opportunities to discover unexpected trends and relations within the collection.
    • Discovery is never by chance: designing for (un)serendipity – finished. Good paper!
      • P AndréJ TeevanST Dumais
      • Serendipity has a long tradition in the history of science as having played a key role in many significant discoveries. Computer scientists, valuing the role of serendipity in discovery, have attempted to design systems that encourage serendipity. However, that research has focused primarily on only one aspect of serendipity: that of chance encounters. In reality, for serendipity to be valuable chance encounters must be synthesized into insight. In this paper we show, through a formal consideration of serendipity and analysis of how various systems have seized on attributes of interpreting serendipity, that there is a richer space for design to support serendipitous creativity, innovation and discovery than has been tapped to date. We discuss how ideas might be encoded to be shared or discovered by “association-hunting” agents. We propose considering not only the inventor‘s role in perceiving serendipity, but also how that inventor‘s perception may be enhanced to increase the opportunity for serendipity. We explore the role of environment and how we can better enable serendipitous discoveries to find a home more readily and immediately.
        • there is “no discovery of a thing you are looking for
        • However, most systems designed to induce or facilitate serendipity have focused on the first aspect, subtly encouraging chance encounters, while ignoring the second part, making use of those encounters in a productive way.
        • Especially, however, we want to offer approaches to get at
          the desired effect of serendipity: insight
        • For us, serendipity is:
          1. the finding of unexpected information (relevant to the goal or not) while engaged in any information activity,
          2. the making of an intellectual leap of understanding with that information to arrive at an insight
        • In our study, a number of participants remarked that they thought of themselves as ‘serendipitous’, and were surprised to find no instances of it in their search behaviour.
          • This is because exploring is not serendipity. See first point above
        • Click entropy, a direct measure of how varied the result clicks are for the query, was found to be significant. That is, a positive correlation between entropy and the number of potentially serendipitous results suggests that people may have clicked varied results not just because they could not find what they wanted, but because they considered more things interesting, or were more willing to go off at a tangent.
        • Arguably however, almost all visualization systems are designed to support such a goal: identifying interesting, but unknown, trends or patterns in data that would not have been visible otherwise.
        • Erdelez‘s [12] so-called ‘super-encounterers’, encountering unexpected information on a regular basis, even counting on it as an important element in information acquisition.
        • Instead of treating serendipity as arcane, mysterious and accidental, we embrace the ability of computers to help us perceive connections and opportunities in various pieces of information
        • presenting such information to users has the potential to increase the overall information the user must interact with. This can lead to two problems: distraction or overload, and the negative consequences of incorrect or problematic recommendations or assumptions
        • It is widely acknowledged that serendipitous discoveries are preceded by a period of preparation and incubation [7]. They are, in that respect, not as ‗serendipitous‘ as we might expect, being the product of mental preparation as well as of an open and questioning mind
        • The challenge from a design perspective may not necessarily be discovering domain literature opportunities, but defining mechanisms for presenting these suggestions in ways that are effective for the investigator. Further to creating a reading list is defining the space to deliver them opportunistically
        • This idea again supposes a form of common language model, a way to express interest or expertise in particular areas, and a way to search for results.
        • In this spectrum, we have also demonstrated that computer science has spent most of it’s design effort perhaps overly focused on trying to create insight (effect of serendipity), by recreating the cause (chance), rather than on, for instance, increasing the rate and accuracy of proposed candidates for serendipitous insight, or developing domain expertise
  • Ordered this, too: Information Visualization: Beyond the Horizon. Has quite a bit on maps that’s going to be needed in the implications for design section
  • What is a Diagram?
    • This paper responds to renewed interest in the centuries old question of what is a diagram. Existing status of our understanding of diagrams is seen as unsatisfactory and confusing. This paper responds to this by proposing a framework for understanding diagrams based on symbolic and spatial mapping. The framework deals with some complex problems any useful definition of diagrams has to deal with. These problems are the variety of diagrams, meaningful dynamics of diagramming, handling change in diagrams in a well formed way, and all of this in the context of semantically mixed diagrams. A brief description of the framework is given discussing how it addresses the problems.
  • Supporting serendipity: Using ambient intelligence to augment user exploration for data mining and web browsing.
    • Has some very Research-Browser-ish bits in it
    • an agent-based system to support internet browsing. It models the user‘s behaviour to look ahead at linked web pages and their word frequencies, using a Bayesian approach to determine relevance. It then colours links on the page depending on their relevance. In evaluation, the colouring was seen as successful, with people tending to follow the strongly advised links most of the time.
  • Retroactive answering of search queries
    • Major search engines currently use the history of a user’s actions (e.g., queries, clicks) to personalize search results. In this paper, we present a new personalized service, query-specific web recommendations (QSRs), that retroactively answers queries from a user’s history as new results arise. The QSR system addresses two important subproblems with applications beyond the system itself: (1) Automatic identification of queries in a user’s history that represent standing interests and unfulfilled needs. (2) Effective detection of interesting new results to these queries. We develop a variety of heuristics and algorithms to address these problems, and evaluate them through a study of Google history users. Our results strongly motivate the need for automatic detection of standing interests from a user’s history, and identifies the algorithms that are most useful in doing so. Our results also identify the algorithms, some which are counter-intuitive, that are most useful in identifying interesting new results for past queries, allowing us to achieve very high precision over our data set.

  • Herding in humans (Ramsey M. Raafat, Nick Chater, and Chris Frith)
    • Herding is a form of convergent social behaviour that can be broadly defined as the alignment of the thoughts or behaviours of individuals in a group (herd) through local interaction and without centralized coordination. We suggest that herding has a broad application, from intellectual fashion to mob violence; and that understanding herding is particularly pertinent in an increasingly interconnected world. An integrated approach to herding is proposed, describing two key issues: mechanisms of transmission of thoughts or behaviour between agents, and patterns of connections between agents. We show how bringing together the diverse, often disconnected, theoretical and methodological approaches illuminates the applicability of herding to many domains of cognition and suggest that cognitive neuroscience offers a novel approach to its study.
  • Alignment in social interactions (M.Gallotti, M.T.Fairhurst, C.D.Frith)
    • According to the prevailing paradigm in social-cognitive neuroscience, the mental states of individuals become shared when they adapt to each other in the pursuit of a shared goal. We challenge this view by proposing an alternative approach to the cognitive foundations of social interactions. The central claim of this paper is that social cognition concerns the graded and dynamic process of alignment of individual minds, even in the absence of a shared goal. When individuals reciprocally exchange information about each other’s minds processes of alignment unfold over time and across space, creating a social interaction. Not all cases of joint action involve such reciprocal exchange of information. To understand the nature of social interactions, then, we propose that attention should be focused on the manner in which people align words and thoughts, bodily postures and movements, in order to take one another into account and to make full use of socially relevant information.
  • Herding and escaping responses of juvenile roundfish to square mesh window in a trawl cod end (This is the only case I can find of 3-D stampeding. Note the [required?] dimension reduction)
    • The movements of juvenile roundfish, mainly haddock Melanogrammus aeglefinus and whiting Merlangius merlangus, reacting to a square mesh window in the cod end of a bottom trawl were observed during fishing experiments in the North Sea. Two typical behavioral responses of roundfish are described as the herding response and the escaping response, which were analyzed from video recordings by time sequences of the movement parameters. It was found that most of the actively escaping fish approached the square mesh window at right angles by swimming straight ahead with very little change in direction, while most of the herded fish approached the net at obtuse angles and retreated by sharp turning. The herding and escaping responses showed significant difference when characterized by frequency distributions of swimming speed and angular velocity, and both responses showed large and irregular variations in swimming movement parameters like the panic erratic responses. It is concluded that an escaping or herding response to the square mesh window could be decided by an interaction between the predictable parameters that describe the stimuli of net and angular changes of fish response, such as approaching angle, turning angle and angular velocity.
  • Assessing the Effect of “Disputed” Warnings and Source Salience on Perceptions of Fake News Accuracy
    • What are effective techniques for combating belief in fake news? Tagging fake articles with “Disputed by 3rd party fact-checkers” warnings and making articles’ sources more salient by adding publisher logos are two approaches that have received large-scale rollouts on social media in recent months. Here we assess the effect of these interventions on perceptions of accuracy across seven experiments (total N=7,534). With respect to disputed warnings, we find that tagging articles as disputed did significantly reduce their perceived accuracy relative to a control without tags, but only modestly (d=.20, 3.7 percentage point decrease in headlines judged as accurate). Furthermore, we find a backfire effect – particularly among Trump supporters and those under 26 years of age – whereby untagged fake news stories are seen as more accurate than in the control. We also find a similar spillover effect for real news, whose perceived accuracy is increased by the presence of disputed tags on other headlines. With respect to source salience, we find no evidence that adding a banner with the logo of the headline’s publisher had any impact on accuracy judgments whatsoever. Together, these results suggest that the currently deployed approaches are not nearly enough to effectively undermine belief in fake news, and new (empirically supported) strategies are needed.

  • Got the official word that I should be charging the project for research. Saved the email this time.
  • Continuing to work on the papers list
  • And in the process of looking at Daniele Quercia‘s work, I found Auralist: introducing serendipity into music recommendation which was cited by
    An investigation on the serendipity problem in recommender systems. Which has the following introduction:

    • In the book ‘‘The Filter Bubble: What the Internet Is Hiding from You’’, Eli Pariser argues that Internet is limiting our horizons (Parisier, 2011). He worries that personalized filters, such as Google search or Facebook delivery of news from our friends, create individual universes of information for each of us, in which we are fed only with information we are familiar with and that confirms our beliefs. These filters are opaque, that is to say, we do not know what is being hidden from us, and may be dangerous because they threaten to deprive us from serendipitous encounters that spark creativity, innovation, and the democratic exchange of ideas. Similar observations have been previously made by Gori and Witten (2005) and extensively developed in their book ‘‘Web Dragons, Inside the Myths of Search Engine Technology’’ (Witten, Gori, & Numerico, 2006), where the metaphor of search engines as modern dragons or gatekeepers of a treasure is justified by the fact that ‘‘the immense treasure they guard is society’s repository of knowledge’’ and all of us accept dragons as mediators when having access to that treasure. But most of us do not know how those dragons work, and all of us (probably the search engines’ creators, either) are not able to explain the reason why a specific web page ranked first when we issued a query. This gives rise to the so called bubble of Web visibility, where people who want to promote visibility of a Web site fight against heuristics adopted by most popular search engines, whose details and biases are closely guarded trade secrets.
    • Added both papers to the corpus. Need to read and code. What I’m doing is different in that I want to add a level of interactivity to the serendipity display that looks for user patterns in how they react to the presented serendipity and incorporate that pattern into a trustworthiness evaluation of the web content. I’m also doing it in Journalism, which is a bit different in its constraints. And I’m trying to tie it back to Group Polarization and opinion drift.

  • Continuing An Introduction to the Bootstrap.
  • This helped a lot. I hope it’s right…
  • Had a thought about how to build the Bootstrap class. Build it using RealVector and then use Interface RealVectorPreservingVisitor to do whatever calculation is desired. Default methods for Mean, Median, Variance and StdDev. It will probably need arguments for max iteration and epsilon.
  • Didn’t do that at all. Wound up using ArrayRealVector for the population and Percentile to hold the mean and variance values. I can add something else later
  • I think to capture how the centrality affects the makeup of the data in a matrix. I think it makes sense to use the normalized eigenvector to multiply the counts in the initial matrix and submit that population (the whole matrix) to the Bootstrap
  • Meeting with Wayne? Need to finish tool updates though.

Doing so strays from the dominant research paradigm, grounded in convictions about the supremacy of rational thought, verbal information, news as cold hard facts, and electoral activities as the gold standard of participatory practices. We advanced arguments for a departure from tradition and elaborated on how the very notions of informed citizenship and political participation are mutating in (and because of) the current media environment.
    • And this is kind of scary: Freedom is on the longest global downward trajectory in 40 years (Freedom House, 2011), democratic failure is at the highest rate since the mid-1980s (Diamond, 1999), and there are indicators of qualitative erosion in democratic practice worldwide (Bertelsmann Foundation, 2012). he people’s view on democratic life appears tepid, in several parts of the world, there are reports of a so-called authoritarial nostalgia among citizens who live in Asian countries that are transforming to democratic systems of governance (Chang, Chu, & Park, 2007) while a mere half (or fewer) of Russians, Poles, Ukrainians, and Indonesians expressed strong support for democratic rule (World Public, 2015).

The ‘Weights’ column actually means ‘scalar’. This issue is that the whole matrix would have to be shown, since the weight exists at the intersection of two items. So a row or column is sort of a sum of weights.

By implication, citizens have social awareness that spans vast territory without having in-depth understanding of specific topics. Related to the idea of monitorial instead of informed citizenship, Pew Center (2008) data identified an emerging group of young (18–34) mobile media users called news grazers. These grazers ind what they need by switching across media platforms rather than waiting for content to be served.

      • Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to arrive at a decision. The authors propose an alternative theoretical perspective, the risk-as-feelings hypothesis, that highlights the role of affect experienced at the moment of decision making. Drawing on research from clinical, physiological, and other subfields of psychology, they show that emotional reactions to risky situations often diverge from cognitive assessments of those risks. When such divergence occurs, emotional reactions often drive behavior. The risk-as-feelings hypothesis is shown to explain a wide range of phenomena that have resisted interpretation in cognitive–consequentialist terms.

If you want to associate a bitcoin address at a later time, then a more detailed biometric analysis would have to take place. Maybe a game. Also, users should be able to create a BC address alias.

  • Good meeting with Wayne yesterday evening
  • Tensorflow playground
  • Continuing The ‘like me’ framework for recognizing and becoming an intentional agent
    • Page 4: Based on the ‘like me’ framework, I hypothesized that it would be possible to demonstrate such tool-use learning at younger ages by transforming the situation. Instead of having the infant sit across the table from the adult, I had them sit side-by-side. In that way the adult’s actions could more easily serve as a blueprint for the child’s own action plans. Recent brain imaging studies with adults show the facilitative effects of seeing a to-be-imitated action from one’s own point of view (Jackson, Meltzoff, & Decety, 2006).
    • Page 5:This study was the first to show infants how to use complex tools ‘from their own perspective.’ Sitting shoulder-to-shoulder with the child closes the gap between the perceived and executed actions. The model becomes more ‘like me.’ 
      • Eyewitness value, photos and images all come from a ‘like me’ framework. As much as possible, we are looking out of the eyes of the witness. This high level of credibility traces all the way back to infancy. Wow. On a related note, this has implications for news reporting using VR.
    • Page 6: Evidently, young toddlers can understand our goals even if we fail to fulfill them. In another study (Meltzoff, 1995; Experiment 2), it was shown that infants did not reenact the target act if  they saw a mechanical device rather than a person performing the ‘slipping’ movements. The device did not look human and had poles as arms and pincers instead of fingers, but it traced the same spatiotemporal pattern as did the person’s yanking. Infants did not pull apart the dumbbell at any higher than baseline levels in this case. They did, however, correctly perform the target act in another condition in which the mechanical device succeeded in pulling apart the dumbbell. This makes sense, because in the case of success the object transformation is visible (it is pulled apart), but in the case of the unsuccessful attempt, there is no object transformation, only a ‘slipping’ motion that has to be interpreted at a different level.
      • Does this mean that we have a ‘wired-in’ model of the intention of others?
    • Page 7: Persistence and emotions as markers of infants’ intention—In further work, I showed 18-month-olds (N = 33) the standard unsuccessful-attempt display, but handed them a trick toy. The toy had been surreptitiously glued shut before the study began. When infants picked it up and attempted to pull it apart, their hands slipped off the ends. This, of course, matched the surface behavior of the adult. The question was whether this imitation of the adults’ behavior satisfied the infants. It did not. When infants matched the surface behavior of the adult, they did not terminate their behavior. They repeatedly grabbed the toy, yanked on it in different ways, and appealed to the adult for help by looking and vocalizing. About 90% (20/23) of those who tried to pull apart the object immediately stared at the adult after they failed to do so (mean latency = 1.74 s). Why were they appealing for help? They had matched the adult’s surface behavior. Evidently, they were striving toward something else: the adult’s goals, not his literal behavior
      • Definately a model of something… And a goal.
    • Page 7: We also conducted related neuroscience work in adults. The results reveal that neural structures known to be involved in adult theory-of-mind tasks (medial prefrontal cortex) are activated in tasks requiring adults to infer unconsummated goals in basic action tasks (Chaminade, Meltzoff, & Decety, 2002; see also Reid, Csibra, Belsky, & Johnson, 2007, for related work). This suggests a tie between the processing of action sequences in terms of goals and more sophisticated aspects of social cognition.
    • Page 7: Our adult commonsense psychology includes a distinction between the types of entities that are accorded goals and intentions and those that are not. We ascribe a goal to the archer not to the arrow that reaches (or misses) the target
      • That’s a fundamental ‘humanness’ definition that Social Trust depends on. If the inferred goals are trustworthy, then slips in behavior are discounted.
    • Page 7: I am currently exploring whether mechanical devices such as social robots can be treated as ‘like me’ based on bodily structure and/ or the type of behavior they exhibit, prompting action imitation by the infant. Preliminary results suggest so.

  • Updated the deployable RatingApp.exe. Asked Andy to set up a Skype meeting so I can demo.
  • Presented and deployed.
  • Made a new CSE that only points to the online Moby Dick, that can be used for query testing.

  • Continuing The ‘like me’ framework for recognizing and becoming an intentional agent
  • Page 2: Perception influences production, and production influences perception, with substantial implications for social cognition.
    • This must be a foundational element of Social Trust. I see you do a thing. I imitate the thing. I feel (not think!) that it is the same thing. I do a thing. You imitate the thing. Think peekaboo. We establish a rapport. This is different from System Trust, where I put something somewhere and it’s still there. System trust may be derived fundamentally from Object Permanence, while Social Trust comes from imitation?
    • This is(?) tied to motor neurons. From Mirror neurons: Enigma of the metaphysical modular brainEssentially, mirror neurons respond to actions that we observe in others. The interesting part is that mirror neurons fire in the same way when we actually recreate that action ourselves.
      • Implications for design? Journalism is definitely built around the ‘like me’ concept that it is built around stories. IR is much less so, and is more data focused.
    • At section 3 – Experiment 1: learning tool-use by observing others
      • We have Social Trust first. Then we learn to use tools. Tools are different from, though related to the environment. They are not ‘like me’, but they extend me (Heidegger again). More later.
  • Page 3: For example, there is an intimate relation between striving to achieve a goal and a concomitant facial expression and effortful bodily acts.
    • This is like the boot loader or initial dictionary entry. Hard-wired common vocabulary.
  • Page 3: Humans, including preverbal infants, imbue the acts of others with felt meaning not solely (or at first) through a formal process of step-by-step reasoning, but because the other is processed as ‘like me.’ This is underwritten by the way humans represent action—the supramodal action code—and self experience
    • So is there a ‘more like me’ and ‘less like me’?
  • Meeting with Wayne this evening
    • Go over notes
    • Coding session
  • ——————
  • Check to see that reports are being made correctly
    • Fix “Get all rated” Numerous issues, including strings with commas
    • Fix “Get Match Counts” all zeros
    • Fix “Get No Match Counts” redundent
    • Change “Get Blacklist (CSV)” to “Black/White list (CSV)
    • Add “Get Whitelist (Google CSE)
    • Change the Sets in getBlack/Whitelist to use maps rather than sets so blacklist culling can be used with more informative rows.
  • Update remote DB and test a few pages. Ran into a problem with LONGTEXT and Postgress. Went back to TEXT
  • Went over Aaron’s ASB slides a couple of times. Introduced him to Partial Least Squares Structural Equation Modeling (PLS-SEM).
  • Present new system to Andy, Margarita and John. Tomorrow…
