Data Specification (thinking about assignment 2)

MGMT 7020   Technology and Project Management

Concepts

There is a critical difference between a

– a particular thing, and

– a concept of a ‘sort of thing’

A concept is a class, a set, a category which

groups particular things that have attributes in common

Forms of Concept definition:

– strict, defined by its boundaries, members are in or out

– fuzzy, defined by its core, members are more-or-less in or out

Much of our thinking (world 2) is

– about concepts

– relating concepts to each other

– relating concepts to particular things

We think in concepts

We talk and read concepts (world 3)

MGMT 7020   Technology and Project Management

An ontology:  ‘Explicit representation of conceptualization’ (Guarino et al. 2009)

Specifying our conceptualisation of a domain ..

Used  to:

develop common understanding of structures

(e.g. the structure of information among people or systems)

make assumptions explicit

(to avoid and identify gaps in understanding)

analyse and formalise different types of knowledge

(e.g. domain knowledge and technical)

uncover missing knowledge

(to surface biases and weaknesses)

enable machine ‘intelligence’

(Trivago)

A formal vocabulary & conceptual framework for a domain  (ie. a semantic network)

A Domain:  A coherent structure of concepts, a field of knowledge, …

Rough Preliminary Conceptual Framework

MGMT 7020   Technology and Project Management

Conceptual Structure – a taxonomy

A Hierarchy of concepts  https:// en.wikipedia.org /wiki/Taxonomy

https://www.earley.com/blog/taxonomy-vs-taxonomy-vs-taxonomy

MGMT 7020   Technology and Project Management

Conceptual Frameworks

Every statement we make draws on concepts

Conceptual Structure – example: Building – a Cross-Section Plan

MGMT 7020   Technology and Project Management

1. Find descriptions of the concepts you are interested in (ie. the terms used to describe it)

definitions – dictionaries, indexes and glossaries of textbooks, encyclopaedia,

thesaurii, wikipedia, etc

uses in practice – the literature

note senses     … begin to narrow relevance by exclusion of out-of-scope senses

A Method for Conceptual Framework Creation

1b. Look for examples (instances)

Exemplars & Prototypes

Core boundary & non examples (conditions for determination)

Difficult cases

3. Identify surrounding concepts

How are they related?

2. Identify the Taxonomy around the concept

type hierarchies – find parent(s), sibling and child concepts (see wordnet)

1a. Identify attributes of the concept

how would you recognise an example of the concept in the wild?

are attributes observable, measurable? (scalar, polar or fuzzy,…?)

Conceptual Framework  Described Formally 2

General Taxonomy (eg. the Standard Upper Ontology, ebXML, …) :

T  >  event  >  act

T  >  physical-object >  animate-object  >  person

( (subt) abbreviated to “>”, T = top)

General Relationships:

(agnt) agent

(attr) attribute

(inst) instrument

(obj) object

(part) part

(loc) location

(eg.  [cat] <- (agnt) <- [sat] -> (loc) -> [mat] )

[author] generic concept, there is an author (or [author:*])

[author : Fred] an individual, the author, Fred

Conceptual Framework  Described Formally 3

Workshop Concepts:

T  >  physical-object >  paper

Workshop Definitions:

act  >  write

[write]   ->  (agnt)  ->  [animate]

->  (obj)     ->  [paper]

Then we can start using the ontology …

[author : Fred]  <-  (agnt)  <-  [write]  ->  (obj)  ->  [paper:#27]

[workshop : ISF19]          (loc)         [city : Canberra]

Example from the ‘Workshop’ domain

Workshop Taxonomy:

“Fred wrote paper number 27”

“paper number 27 wrote Fred”

A machine can detect this invalid statement…

Concepts & Ontology

The 3 worlds idea can be seen as an ‘ontological’ theory That is, it posits 3 concepts about the sorts of things that exist: material entities, forces and structures thinking (a process) abstract entities (concepts and relationships)

The  Big  Ideas

Why  Study  These?

Because they specifically underlie the key organisational technologies  and, more generally, underlie our capacity to understand our world!

Now, using your knowledge of the language of the domain,

start to sketch a rich picture.

Data & Abstraction

MGMT 7020   Technology and Project Management

Data Base Technology

Stores data !

eg. the temperature of this room recorded every 10 mins

eg. all the relevant data relating to you is in the student database

How do we tell a machine what the data is about?

(eg. how does it know 22 is the temperature of this room etc)

We analyse the domain and develop a model of the

SORT of data we want.

Then build systems to capture the actual data and process it…

‘meta-data’

‘data’

MGMT 7020   Technology and Project Management

Data model (meta-data):

Diagram of data entities and their relationships

Not the data itself

Entity-relationship (ER) diagrams:

Data models use basic graphical symbols to show the organization of and relationships between data-entities

Provides a global reference to an organization’s data structures.

Useful for designing a database structure, semantic web, etc.

Exercise:

Write an English sentence equivalent to the E-R diagram below.

(A “Vet” is a Veterinary doctor who looks after animals

A “Practice” is a place where a doctor works)

This is a data model – a kind of Conceptual Framework

MGMT 7020   Technology and Project Management

Entity (a concept, a set, a class):

An Entity is a concept identifying a set of Objects

about which we want to record data.

eg. Employee.

Employee

Meta-Data – Basic Ideas

Attribute:

An Attribute identifies a property all instances of an entity have.

eg.

Employee:

employee number

employee name

employee address

employee salary

Employee

Employs

Department

An event (world 1) establishes a relationship between objects

eg. Schmit was employed by the Management Department on January 1 2017

The ’employs’ event generated an instance of the ‘Employs’ Entity.

Obtain a “narrative”

(e.g. from observation, a business analysis, an interview, etc.)

Identify the entities needed

Look for objects (often nouns) in the narrative

Detect the relationships between the entities
