Information Systems Test 2

Platform businesses don't own the '______ ___ __________' instead, they own the '______ __ ___________'

'means of production', 'means of connection'

If a '_______' model can be derived (maybe, maybe not), it can be put into use (deployed) to generate a ________ of the output variable (Y), given new sets of input data (X)

'quality', prediction

Hybrid impact

(switching between positive & negative): • Massive multiplayer online games » positive network effects when congestion is low (no lag) » negative if a tipping point is reached and more users lead to a slower system response (Gallaugher calls: congestion effect)

T/F network effects always have a positive impact

False: sometimes more users is worse - value depletion. - eBay (more sellers may lead to smaller margins)

The most common algorithm is called the _________.

apriori algorithm

Collaborative Filtering is also a technique to identify __________

associations

Lift

controls for the support (frequency) of the consequent. Lift of an association rule is the ratio of observed support compared to that expected if X & Y were independent.

In a Tippy market, the firm that reaches a ...

critical mass of users (or complementors) first (a tipping point) will likely win the entire market - "winner takes all" - especially when the growth in network effects is exponential.

The internet is a ______

network of networks, connecting many private, business, academic, and government computers worldwide

fabricated content

new content that is 100% false, designed to deceive and do harm

In unsupervised learning input data (x) is available but

no corresponding output data (Y) -- so, no known outcomes. So, developing a mapping function is not feasible

Misinformation:

False information that is held or spread, regardless of intent

Disinformation:

False information that is spread with the intent to mislead.

T/F: Association Rules Mining determines causation

False: it only traces evidence of association

T/F: every company posseses data about social graphs

User-curated shopping (The Fancy, Lyst)

- Users create and share lists of products and services for others to shop from

What is the chicken-and-egg problem?

-Cold-start problem. • A new platform doesn't initially create enough value to attract new users. It's not economical for consumers to join the platform when there are no producers and vice versa

Is hype news misinformation?

-Hype news is information that is taken out of context, exaggerated, and overgeneralized to attract public attention. -Hype news can be more insidious because it is based on a grain of truth, and its deletion raises the specter of censorship. To that extent, hype news is a pernicious form of information distortion that cannot be easily eliminated - Distinct from "fake news," which is "fabricated information that mimics news media content in form but not in organizational process or intent"

Quickbooks started moving towards a platform by:

Negative (Balancing) Feedback Loop is a...

-Self-diminishing (weakening ---) trend -Negative feedback keeps a positive effect/externality from growing indefinitely, pulling a system back towards an equilibrium (ex body temp) (i.e., reducing fluctuations in the output). • Important in nature! • Negative does not necessarily mean 'bad'

lift roughly = 1

-indicates almost no association - the events seem independent.

Lowering costs - Economies of scale def

-product becomes cheaper to produce as business increase size and output, increasing scale leads to lower cost per unit of output( cost per unit decreases as fixed costs are spread out over more units)

Increasing value - network effects def

-product becomes more valuable as more users use it (ie as more users demand to use it (bc "demand side")) -Network effects help build a moat - leading to high/repeat rates of engagement, higher margins

2 main types of network effects:

-same side -cross-side

2 sided markets can exhibit both same-side & cross-side networks, Xbox example of same-side and cross-side

-same-side: if there are more Xbox owners, each player can play against more owners and each owner benefits more from their console -cross-side: if there are more console game developers, then owners derive more value from their devices by having a larger selection of games

Positive Feedback Loop is a ...

-self-reinforcing (strengthening) trend -a company gains customers which in turn, attracts more customers -Or A company loses customers, which in turn, leads to other customers leaving -"positive" does not necessarily mean "good"

Insights are:

-value obtained through analytics. Output -novel and actionable

What is a social graph?

A Social Graph is "a mapping of everyone and how they are related." • From an individual perspective: A map of all relevant links or connections for one member of a social network. • May also include things, organizations, products, etc. • Conceptually, it can be thought of as a network of things and connections between them

Regression supervision learning problem:

A regression problem is when the output variable (Y) is a value, such as "dollars" or "weight"

Crowdsourcing

A sourcing model in which individuals or organizations obtain goods and services, including ideas and finances, from a large, relatively open and often rapidly-evolving group of internet users; it divides work between participants to achieve a cumulative result, younger term with more emphasis on technology as an enabler
