This document provides an overview of the CS-651 Intelligent Information Systems course for Spring 2022, taught by Khalid Saleem. It discusses key topics that will be covered, including data mining, knowledge discovery in databases, the differences between data, information, and knowledge. It also outlines different types of information systems like decision support systems, executive support systems, and transaction processing systems. Examples of real-world big data applications are provided, such as how Obama's 2012 re-election campaign used data analytics. Recommended readings for the course are listed at the end.

3. So, we need to device right
questions for the computers to
answer.
Come up with systems which can
help us in this activity ….

knowledge ….

5. PSU definition of IIS Research
 The goal of the Intelligent Information Systems
Research is to explore and support all levels of
research that will improve and enhance our ability
to generate, manage, search, and mine
information and knowledge. Current research
covers Internet database design and analysis,
mobile Web computing, Web mining and
navigation, Web agents, novel and intelligent
Web tools, multimedia retrieval, Web and internet
models, Web usage, automatic content analysis
and digital libraries, Web search, niche search
engines, semantic web, scientific databases, data
mining, and information retrieval.
 All about Web ….

6. Knowledge
Information
Data
 Data : Simple things; easily captured, structured,
transferred, compressible and quantifiable
 Information : Relevant and related data having
some purpose; needs consensus on meaning and
human mediation necessary
 Knowledge : Valuable information from human
mind; contextual; hard to capture electronically and
structure; mostly tacit

8. Definition - DM and KDD
 Data mining(DM) is a step in the knowledge
discovery process consisting of particular data
mining algorithms that, under some acceptable
computational efficiency limitations, find patterns
or models in data
 Knowledge discovery in databases (KDD)
(Fayyad et al, 1996), is the process of identifying
valid, novel, potentially useful, and ultimately
understandable patterns or models in data.

9. Data Items
 Data items refer to an elementary description
of things, events, activities, and transactions
 that are recorded, classified, and stored but
are not organized to convey any specific
meaning.
 Data items can be numbers, letters, figures,
sounds, or images. Examples of data items
are a
 student grade in a class and the number of
hours an employee worked in a certain week.

10. Information
 Information refers to data that have been
organized so that they have meaning and
value to the recipient.
 For example, a grade point average (GPA) is
data, but a student’s name coupled with his or
her GPA is information.
 The recipient interprets the meaning and
drawsconclusions and implications from the
information.

11. Knowledge
 Knowledge consists of data and/or
information that have been organized and
processed
 to convey understanding, experience,
accumulated learning, and expertise as they
apply to a current business problem. For
example, a company recruiting at your
university has found
 Over time that students with grade point
averages over 3.0 have had the most success
in its management program.
 Based on its experience, that company may

16. Task – LOSE WEIGHT!
 UK survey - relevant respondents were asked to
name the top reasons as to how using dieting
apps on their Smartphone has helped them to
lose weight. The five highest ranked answers
emerged as follows:
 1. Easier to track calories and food intake at the
push of a button (47%)
 2. Can check calorie content of items before
deciding to eat them (36%)
 3. Helpful for planning healthy and nutritious
meals in advance (32%)
 4. Helps keep me motivated (24%)
 5. Cheaper and easier alternative to diet books
and magazines (18%)

17. Information System

18. Big Data …. Open Data

19. Magnitude of Data
 Human brain capacity 2.5 PETABYTES
 Total digital data created 422 EXABYTES (2008)
 Web size - 98 PETABYTES (2010)
 Total genome sequences of all people on Earth 4.75
EXABYTES
 Web users - 2 Billion + (2011)
 World’s digital storage capacity 1 ZETTABYTE (2011)
 Digital data created 1.8 ZETTABYTES (2011) 2.7 ZB
(2012)
 Digital Data to be produced - 35 ZETTABYTES (by 2020 )
 Drastic price reduction in per Gigabyte production of storage
 => All data is being or is going to be conserved!
 => Huge data centres

21. Data Equity
 UK Report : Annual economic benefit of these big
data analytics can be above 40 billion £ for UK,
for 2017 from Government and Enterprise point of
view.
 US government has dedicated 200 million dollars
for research to handle big data
 $10 million data project at the University of
California, Berkeley, support for a geosciences
data effort called Earth Cube, and more.

22. Some Scenarios …

23. Obama’s secret weapon in re-
election
 With a sluggish economy, unemployment
teetering at around the eight per cent mark, and
growing anti-Obama sentiment in some parts of
the country, a second term seemed an uphill task
for Obama and it was going to take an
extraordinary campaign to make it happen
 From the get-go David Axelrod, the brain behind
the Obama campaign, recognised the role that
data and information could play in the election.
The process had been initiated in 2008 but
databases were scattered and it wasn’t until the
2010 midterm elections that the Democratic
Party, despite heavy losses, was able to
streamline the data to accurately forecast results
in a meaningful way.

24. Obama’s secret weapon in re-
election
 Pakistani scientist Rayid Ghani
 Ghani’s job was to make sense of huge amounts of
information
“The core of the work I was doing was looking at a
large amount of data and making sense of it to help
other people make better decisions”
If the 2008 campaign was about charisma and hope,
the 2012 campaign was about science and data.
 How data helps you, is it makes you more efficient and it
helps you spend your money carefully and in the right
way

25. Collaborative Social IS
The data content published by individuals on web,
specifically in a collaborative environment like social
forum, blog, games etc.
Data can be analysed/created by thousands of users
(crowd-sourcing initiatives).
• Right after the earthquake in Haiti in 2009, the
company holding the license to use geo-imagery
opened up the map data of Haiti to general public.
The web users all over the world examined the
imagery and within a couple of days populated the
map with information like refugee camps, hospitals,
damaged buildings. The relief workers in the area
used the map to organise the relief work

Millions of transactions over internet, e.g.
online game servers, business transaction
portals or other business to business oriented
services

one terabyte of data per day
• WallMart Data Warehouse Intelligence
• Querying these transactions in Column
databases!
• NoSQL Databases
• Graph Databases
