Systems Social Seience: A Design Inquiry Approach For Stabilization And Reconstruction Of Social Systems, Barry G. Silverman
Systems Social Seience: A Design Inquiry Approach For Stabilization And Reconstruction Of Social Systems, Barry G. Silverman
Barry G Silverman
This paper explores novel approaches under the design inquiry paradigm that promise to help organizations better understand and solve socio-technical dilemmas. Design inquiry is contrasted with scientific inquiry (Section 1). Section 2 presents a meso-scale model of models methodology for design inquiry that synthesizes systems science, agent modeling and simulation, knowledge management architectures, and domain theories and knowledge. The goal is to focus computational science on exploring underlying mechanisms (white box modeling) and to support reflective theorizing and discourse to explain social dilemmas and potential resolutions. Section 3 then describes an evolving agent modeling and simulation testbed while Section 4 …
Rich Socio-Cognitive Agents For Immersive Training Environments: Case Of Nonkin Village, Barry G. Silverman, David Pietrocola, Ben Nye, Nathan Weyer, Oleg Osin, Dan Johnson, Ransom Weaver
Rich Socio-Cognitive Agents For Immersive Training Environments: Case Of Nonkin Village, Barry G. Silverman, David Pietrocola, Ben Nye, Nathan Weyer, Oleg Osin, Dan Johnson, Ransom Weaver
Barry G Silverman
Demand is on the rise for scientifically based human-behavior models that can be quickly customized and inserted into immersive training environments to recreate a given society or culture. At the same time, there are no readily available science model-driven environments for this purpose (see survey in Sect. 2). In researching how to overcome this obstacle, we have created rich (complex) socio-cognitive agents that include a large number of social science models (cognitive, sociologic, economic, political, etc) needed to enhance the realism of immersive, artificial agent societies. We describe current efforts to apply model-driven development concepts and how to permit other …
Holistically Evaluating Agent Based Social System Models, Gnana K. Bharathy, Barry G. Silverman
Holistically Evaluating Agent Based Social System Models, Gnana K. Bharathy, Barry G. Silverman
Barry G Silverman
The philosophical perspectives on model evaluation can be broadly classified into reductionist/logical positivist and relativist/holistic. In this paper, we outline some of our past efforts in, and challenges faced during, evaluating models of social systems with cognitively detailed agents. Owing to richness in the model, we argue that the holistic approach and consequent continuous improvement are essential to evaluating complex social system models such as these. A social system built primarily of cognitively detailed agents can provide multiple levels of correspondence, both at observable and abstract aggregated levels. Such a system can also pose several challenges, including large feature spaces, …
A Systems Approach To Healthcare: Agent-Based Modeling, Community Mental Health, And Population Well-Being, Barry G. Silverman, Nancy Hanrahan, Gnana K. Bharathy, Kim Gordon, Dan Johnson
A Systems Approach To Healthcare: Agent-Based Modeling, Community Mental Health, And Population Well-Being, Barry G. Silverman, Nancy Hanrahan, Gnana K. Bharathy, Kim Gordon, Dan Johnson
Barry G Silverman
Purpose Explore whether agent-based modeling and simulation can help healthcare administrators discover interventions that increase population wellness and quality of care while, simultaneously, decreasing costs. Since important dynamics often lie in the social determinants outside the health facilities that provide services, this study thus models the problem at three levels (individuals, organizations, and society). Methods The study explores the utility of translating an existing (prize winning) software for modeling complex societal systems and agent's daily life activities (like a Sim City style of software), into a desired decision support system. A case study tests if the 3 levels of system …
An Embeddable Testbed For Insurgent And Terrorist Agent Theories: Insurgisim, Barry G. Silverman, Aline Normoyle, Praveen Kannan, Richard Pater, Deepthi Chandrasekaran, Gnana K. Bharathy
An Embeddable Testbed For Insurgent And Terrorist Agent Theories: Insurgisim, Barry G. Silverman, Aline Normoyle, Praveen Kannan, Richard Pater, Deepthi Chandrasekaran, Gnana K. Bharathy
Barry G Silverman
Many simulators today contain traditional opponents and lack an asymmetric insurgent style adversary. InsurgiSim prototypes an embeddable testbed containing a threat network of agents that one can easily configure and deploy for training and analysis purposes. The insurgent network was constructed inside a socio-cognitive agent framework (FactionSim-PMFserv) that includes: (a) a synthesis of best-of-breed models of personality, culture, values, emotions, stress, social relations, mobilization, as well as (b) an IDE for authoring and managing reusable archetypes and their task-sets (Sect. 2). Agents and markups in this library are not scripted, and act to follow their values and fulfill their needs. …
Affordances In Ai, Benjamin D. Nye, Barry G. Silverman
Affordances In Ai, Benjamin D. Nye, Barry G. Silverman
Barry G Silverman
Affordances in AI refer to a design methodology for creating artificial intelligence systems that are designed to perceive their environment in terms of its affordances (Sahin et al. 2007). Affordances in AI are adapted from affordances introduced in The Ecological Approach to Visual Perception by James J. Gibson (1979). Design methodologies in the applied sciences use affordances to represent potential actions that exist as a relationship between an agent and its environment. This approach to artificial intelligence is designed for autonomous agents, making it suitable for robotics and simulation.
Validating Agent Based Social Systems Models, Gnana K. Bharathy, Barry G. Silverman
Validating Agent Based Social Systems Models, Gnana K. Bharathy, Barry G. Silverman
Barry G Silverman
Validating social systems is not a trivial task. The paper outlines some of our past efforts in validating models of social systems with cognitively detailed agents. It also presents some of the challenges faced by us. A social system built primarily of cognitively detailed agents can provide multiple levels of correspondence, both at observable and abstract aggregated levels. Such a system can also pose several challenges including large feature spaces, issues in information elicitation with database, experts and news feeds, counterfactuals, fragmented theoretical base, and limited funding for validation. Our own approach to validity assessment is to consider the entire …
Social Learning And Adoption Of New Behavior In A Virtual Agent Society, Benjamin D. Nye, Barry G. Silverman
Social Learning And Adoption Of New Behavior In A Virtual Agent Society, Benjamin D. Nye, Barry G. Silverman
Barry G Silverman
Social learning and adoption of new behavior govern the rise of a variety of behaviors: from actions as mundane as dance steps to those as dangerous as new ways to make IED detonators. However, agents in immersive virtual environments lack the ability to realistically simulate the spread of new behavior. To address this gap, a cognitive model was designed that represents the well-known socio-cognitive factors of attention, social influence, and motivation that influence learning and the adoption of a new behavior. To explore the effectiveness of this model, simulations modeled the spread of two competing memes in Hamariyah, an archetypal …

Gameplay, Interactive Drama, And Training: Authoring Edutainment Stories For Online Players (Aesop), Barry G. Silverman, Michael Johns, Ransom Weaver, Joshua Mosley
Barry G Silverman
This paper describes initial efforts at providing some of the technological advances of the videogame genres in a coherent, accessible format to teams of educators. By providing these capabilities inside an interactive drama generator, we believe that the full potential of educational games may eventually be realized. Sections 1 and 2 postulate three goals for reaching that objective: a toolset for interactive drama authoring, ways to insulate authors from game engines, and reusable digital casts to facilitate composability. Sections 3 and 4 present progress on those tools and an in-depth case study that made use of the resulting toolset to …
Constructing Virtual Asymmetric Opponents From Data And Models In The Literature: Case Of Crowd Rioting, Barry G. Silverman, Michael Johns, Kevin O'Brien, Ransom Weaver, Jason Cornwell
Constructing Virtual Asymmetric Opponents From Data And Models In The Literature: Case Of Crowd Rioting, Barry G. Silverman, Michael Johns, Kevin O'Brien, Ransom Weaver, Jason Cornwell
Barry G Silverman
This paper describes an effort to integrate human behavior models from a range of ability, stress, emotion, decision theoretic, and motivation literatures into a game-theoretic framework appropriate for representing synthetic asymmetric agents and scenarios. Our goal is to create a common mathematical framework (CMF) and an open agent architecture that allows one to research and explore alternative behavior models to add realism to software agents - e.g., physiology and stress, personal values and emotive states, and cultural influences. Our CMF is based on a dynamical, game-theoretic approach to evolution and equilibria in Markov chains representing states of the world that …
Modeling Factions For ‘Effects Based Operations’: Part Ii – Behavioral Game Theory, Barry G. Silverman, Gnana Bharathy, Benjamin Nye, Roy Eidelson
Modeling Factions For ‘Effects Based Operations’: Part Ii – Behavioral Game Theory, Barry G. Silverman, Gnana Bharathy, Benjamin Nye, Roy Eidelson
Barry G Silverman
Military, diplomatic, and intelligence analysts are increasingly interested in having a valid system of models that span the social sciences and interoperate so that one can determine the effects that may arise from alternative operations (courses of action) in different lands. Part I of this article concentrated on internal validity of the components of such a synthetic framework – a world diplomacy game as well as the agent architecture for modeling leaders and followers in different conflicts. But how valid are such model collections once they are integrated together and used out-of-sample (see Section 1)? Section 2 compares these realistic, …

Challenges Of Country Modeling With Databases, Newsfeeds, And Expert Surveys, Barry G. Silverman, Gnana K. Bharathy, G. Jiyun Kim
Barry G Silverman
According to expert practitioners and researchers in the field of human behavior modeling ([Silverman et al., 2002; Pew and Mavor, 1998; Ritter et al., 2003]), a common central challenge now confronting designers of HBM (human-behavior-modeling) applications is to increase the realism of the synthetic agents' behavior and coping abilities. It is well accepted in the HBM (human-behavior-modeling) community that cognitively detailed, "thick" models are required to provide realism. These models require that synthetic agents be endowed with cognition and personality, physiology, and emotive components. (We will hereafter refer to these rich models as "cognitively detailed models" or "thick agents.") To …

1. (n.) An affordance is an action possibility formed by the relationship between an agent and its environment (J. Gibson 1977; J. Gibson 1979). For any combination of agent or environment, any given affordance either exists or does not exist. There is no middle ground. The most inclusive definition of affordances considers only the physical possibility of an action occurring. An agent does not need to be aware of the afforded action, such as the affordance of opening a secret door. This definition is rooted in perceptual psychology and its primary source is The Ecological Approach to Visual Perception by …

A Demonstration Of The Pmf-Extraction Approach: Modeling The Effects Of Sound On Crowd Behavior, Jason Cornwell, Barry G. Silverman, Kevin O'Brien, Michael Johns
Barry G Silverman
The vast majority of psychology, sociology, and other social-science literature describing human behavior and performance does not reach the eyes of those of us working in the modeling and simulation community. Our recent work has been concerned with the extraction and implementation of Human Behavior Models(HBMs)/ Performance Moderator Functions(PMFs) from this literature. This paper demonstrates how our methodology was applied to extract models of the effects of music and sound on both individuals and groups and to implement them in a simulated environment. PMFs describing how several classes of sound affect decision-making and performance were constructed based on well-established psychological …
