A brief history of the WWW
1989
CERN physicist Tim Berners-Lee lays out a proposal for information management called “Mesh”
Original proposal available from http://www.w3.org/History/1989/proposal.html
1990
Berners-Lee changes name to “World Wide Web” while writing code for the Mesh
Creates three fundamental building blocks:
HTML
URL (later called URI)
HTTP

A brief history of the WWW
1990
First web page appears on the Internet
1991
Web available for access to people outside of CERN
1993

A brief history of the WWW
Design principles for WWW adopted by the W3C:
Decentralization (no one controls content on the web)
Non-discrimination (net neutrality)
Bottom-up design (Open source, participatory approach to maintaining web code)
Universality (Agnostic to computing platforms or hardware)
Consensus (Participatory approach to web standards)

A brief history of the WWW
1993
Mark Andreessen from NCSA releases Mosaic – the first graphical browser for the web
1994
Andreessen, with two colleagues form Mosaic Communications Corporation and release the first commercial web browser: Netscape Navigator
First International WWW conference is organized at CERN in May 1994
1996—2000
Dot com boom (“Get large or get lost” mantra) and birth of several first generation search engines and e-commerce sites (Yahoo, Excite, Lycos, Altavista, Amazon, …)
Bangalore Science Forum, February 2016
A brief history of the WWW
2001—2002
Dot com bust. Major web and Internet companies go bankrupt (Excite, Lycos, Nortel Networks, Worldcom,...)
2002–
Web 2.0. Web reinvents itself as a participatory social medium bringing social science and psychology central to thinking about the web.
Bangalore Science Forum, February 2016
Models of the Web
The web is unlike any other technology developed so far
Unlike say cars or washing machines, there is only one web
Is the web a “technology” or a “tool” that we use or is it something else?
Notable paradigms of the Web considered by researchers:
Very large database
Digital library / Repository
A cognitive extension of ourselves
Participatory socio-cognitive space
Bangalore Science Forum, February 2016
Web as a Database
Early approaches (mid '90s) to model the Web
Focused on the “semi-structured” nature of the Web and as a special case of managing structured (RDBMS) databases
Research objectives: structured and rich query semantics
Examples include: [AMM 97], [Eng 98], WebQL
An example WebQL query
Source: http://en.wikipedia.org/wiki/WebQL
Bangalore Science Forum, February 2016
Web as a Digital Library
Shift from:
Strict notions of “query” Looser notions of “retrieval” and “relevance”
Strict notions of “schema” Looser notions of “ontology”
Emphasis still on retrieving information
Web still seen as a passive repository of information
Examples: [GR+ 97], [HMA 03]
Bangalore Science Forum, February 2016
Web as a Cognitive Extension of Ourselves
Rooted in Vannevar Bush's interpretation of hypertext reflecting the way information is organized in human brains
Focus on interpreting hyperlinks, rather than (just) data on web pages
Hyperlink as a(n):– Relevance indicator
– Endorsement
– Attention pathway
Examples: PageRank [BP 98], HITS [GKR 98]
Memex
Bangalore Science Forum, February 2016
Web as a Socio-cognitive Space
Most contemporary paradigm for understanding the web
Web as an active, participatory, social space – people are no longer users, but participants
Shift of emphasis from retrieving information from the web to engaging users with the web
The Web uses us as much as we use the Web! Examples:
Crowdsourcing, Participatory authoring, Push notifications on social media, Click-baiting, etc.
The global mind and superintelligence

Web Science
From www.webscience.org
“Nothing like the Web has ever happened in all of human history. The scale of its impact and the rate of its adoption are unparalleled. This is a great opportunity as well as an obligation. If we are to ensure the Web benefits the human race we must first do our best to understand it.
The Web is the largest human information construct in history. The Web is transforming society. In order to understand what the Web is, engineer its future and ensure its social benefit we need a new interdisciplinary field that we call Web Science.”
Bangalore Science Forum, February 2016
Social Machines
Represents a class of environments comprising of interplay between humans and technology
Outputs of social machines a result of both human and algorithmic decisions
Building blocks of the global socio-cognitive space
“The Web is an engine to create abstract social machines”
– Tim Berners-Lee, Weaving the Web [BH 09]

The psychological dimension of theonline free-speech debates
Bangalore Science Forum, February 2016
The Free Speech Conundrum
Bangalore Science Forum, February 2016
The Free Speech Conundrum
The holy grail of democratic societies – freedom of speech (and expression) – is suddenly at the center of a new found controversy
At the core of this debate is a call to distinguish between “free speech” and “bad speech”
Bangalore Science Forum, February 2016
Free Speech and Bad Speech
The line is not always clear:
Disagreeing with popular opinion (free speech)
Supporting/opposing a political party (free speech)
Racial slur (bad speech)
Inciting mob violence publicly (bad speech)
Scholarly writing criticizing government or specific religions (free speech considered bad speech in some places)
Artistic depiction that offends religious sentiments (let's not even go there!)
Bangalore Science Forum, February 2016
Characterizing Speech
Claim:
The free speech versus bad speech debate presents a false dilemma, which can never be completely resolved
Need:
Semantic characterization of speech and conversations and creating awareness and tool-support for online conversations based on this characterization
Bangalore Science Forum, February 2016
Abstraction and Expression
Articulation of our objective understanding of something
Communicates an idea
Articulation of our subjective feeling about something
Communicates an emotion
Bangalore Science Forum, February 2016
Abstraction and Expression
Reporting: mostly abstraction
Opinion: mix of abstraction and expression
Emotional reaction: mostly expression
Bangalore Science Forum, February 2016
Abstraction
● Semantic meta-construct used to build our world view
● Processing is resource intensive (“System 2” in Prospect Theory [KT79] terminology)
● Subject to innate cognitive resistance in assimilation due to factors like bounded rationality and conformance pressures

Bangalore Science Forum, February 2016
Abstraction and Conformance
Asch Conformity Experiments
Bangalore Science Forum, February 2016
Conformance and Diffusion of Ideas
Information diffusion is faster in sparsely connected parts of a network, rather than densely connected (entrenched) parts due to conformance effects.
Node d in the above figure does not switch to the new idea because of conformance pressures from nodes e, f and g
Image Source: [Sri 06]
Bangalore Science Forum, February 2016
Models for Diffusion of Ideas
Typically based on an element of “criticality” balancing: ability to communicate new idea, and pressure to conform to existing ideas
Example models [EK 10]
Percolating clusters
Ising model
Cluster density based diffusion
Bangalore Science Forum, February 2016
Expression● Semantic construct encapsulating
our emotional state for communication
● Subconsciously affects receiver's emotional state by means of emotional contagion
● Emotional contagion also spreads through the web (Ex: Facebook Experiment [KGH 14])
● Characteristically different from spread of ideas, which have a natural resistance to assimilation
Images source: Wikipedia
Bangalore Science Forum, February 2016
Spread of Emotions
Models based on spread of epidemics, useful in modeling spread of emotions
Emotions are psychosomatic phenomena causing both cognitive and physical affect
Intense emotional states induce a state of trauma that have long range repercussions like PTSD
Example epidemic models [EK 10]
– SIR (Susceptible-Infected-Recovered/Resistant) useful for modeling spread of intense emotions in a population
– SIS (Susceptible-Infected-Susceptible) useful for modeling spread of mild emotions in a population
Bangalore Science Forum, February 2016
Abstraction versus Expression
Objective belief
Asserts an idea
Humans have innate resistance towards ideas thrown at them
We need to have an “open mind” to entertain new abstractions
Subjective emotion
Communicates a feeling
Humans have innate “anti-resistance” towards emotions thrown at them
We need to be “mindful” of our emotional state to be unaffected by an incoming emotion
Bangalore Science Forum, February 2016
Mental Model
Axiomatic framework within which we perform reasoning.
Encapsulates underlying assumptions, ground truths and inference rules
Active mental model
Reasoning and deduction carried out within the framework of the currently active mental model
Any input that challenges the currently held mental model usually elicits an emotional reaction (laughter, terror, etc.)
Linking Abstractions and Expressions

Bangalore Science Forum, February 2016
The Intense Online World
Online communication tend to be more intense and overwhelming due to following factors:– Lack of coherence between mental models (due to
anonymity, asynchrony, solipsism, etc.)
– Interplay between abstractive and expressive content in conversation
Emotions spread faster than ideas due to anti-resistance
Spread of emotions greatly complicates the spread of ideas
Bangalore Science Forum, February 2016
Online Collectives
Bangalore Science Forum, February 2016
Wisdom of Crowds?
Not all groups of people form“wise” crowds!
Bangalore Science Forum, February 2016
Coagulation
Abstraction and Expression can affect group behaviour in different ways
A given abstraction or expression can “coagulate” over a group of people (most people in the group think the same way / most people in the group feel the same way)
Coagulation in abstraction and expression can explain some failures of crowdsourcing efforts
Bangalore Science Forum, February 2016
Classification of Groups [SS 15]
Some coherence inabstractions(Ex: NPOV, NOR,Vfor Wikipedia)
High coagulation
Low coagulation
Bangalore Science Forum, February 2016
Classification of Groups
Crowds
Group of people having shared attention but no shared abstraction or shared expression
Rich in insights due to diverse opinions
No major emotional contagion
Members act as individuals
Pose high cognitive load on members
Unstable
Wise Crowds
Share some common abstraction in the form of “ground rules” to facilitate management of diverse opinions without degenerating
Bangalore Science Forum, February 2016
Classification of Groups
Herds
Group sharing a common abstraction
“Herd mentality” pertains to every member of the group thinking in the same way
High in persuasive power
Low on collective insight
Manipulable by external forces if the characteristics of the herd are known
Bangalore Science Forum, February 2016
Classification of Groups
Mobs
Groups sharing a common emotional state
Common emotional state could be either positive emotion (jubilant football fans) or negative emotion (lynch mobs)
Need not have common abstraction (members of an angry mob may each be venting personal frustrations through the mob)
Highly unpredictable behaviour
Bangalore Science Forum, February 2016
Classification of Groups
Gangs
Groups sharing both a common abstraction and common emotion
All members of the group think and feel the same way about something
Passionate and highly persuasive
Common emotion could be positive (The researcher “gang of four” on design patterns) or negative (bandits and other organized criminals)
Powerful and highly impactful collective actions

Free Speech Revisited
What appears as the online free speech conundrum is actually a complex phenomenon caused by abstraction, expression, dissonance across mental models and group coherence of abstractions and expressions and amplified by the scale of the Web
The issue is not (just) a question of what is or should be legal provisions around online speech
We need better models to understand cognitive and emotional aspects of human communication and their impacts on a global scale
Linearly extrapolating existing models from social psychology bound to fail because, never before in human history was there a global socio-cognitive conversational space like the Web
Bangalore Science Forum, February 2016
The Web and the Mind
The web is affecting what we think and feel – thus molding us at a very fundamental level, offering both opportunities and challenges
Our understanding of web-scale cognitive phenomena too premature to advocate any form of social or regulatory solutions
Web Science: A rich area of research for enthusiastic and curious minds!
