Object relations?
Do I know you?
How is relation between objects established?
How to predict the interaction?

An object, example 1
• but first, how is an individual object defined?

An object, example 2

Relation, example
• Based on our familiarity with them, it is not hard to predict how they will interact when they meet.
![Page 6: Model: Relations and Groups Prabin Gautam CS/SE 6361, Fall 2013 Under the guidance of: Prof. Lawrence Chung University of Texas at Dallas](https://reader036.vdocuments.us/reader036/viewer/2022081516/56649e175503460f94b02f78/html5/thumbnails/6.jpg)
Known, Unknown
• But objects are not always familiar, then predictingrelation becomes difficult.
• known objects: - degree of knowledge/information is different from object to object.- can have unfamiliar traits.
• unknown objects: - can have some familiar traits and attributes, or- can be completely strange without any familiar traits

Other relation Examples
• Establishing, predicting relations applies in any field.• Interactions can be correctly predicted based on better
understanding of relation.
• Other examples:- two biological proteins- two chemical compounds- two business companies- politics: competing views, truth and rhetoric.- economy: two models. Are they complimentary, mutually exclusive, and competitive?- data science: two data- countries: natural allies?- people: compatibility- sports: team members chemistry

Grouping
• How can we categorize them to meaningful group?• How are object relation map and grouping related?
![Page 9: Model: Relations and Groups Prabin Gautam CS/SE 6361, Fall 2013 Under the guidance of: Prof. Lawrence Chung University of Texas at Dallas](https://reader036.vdocuments.us/reader036/viewer/2022081516/56649e175503460f94b02f78/html5/thumbnails/9.jpg)
Grouping
• By shapes?
![Page 10: Model: Relations and Groups Prabin Gautam CS/SE 6361, Fall 2013 Under the guidance of: Prof. Lawrence Chung University of Texas at Dallas](https://reader036.vdocuments.us/reader036/viewer/2022081516/56649e175503460f94b02f78/html5/thumbnails/10.jpg)
Grouping
• By size?
• It depends on the purpose.What do we want to achieve by forming a group?
![Page 11: Model: Relations and Groups Prabin Gautam CS/SE 6361, Fall 2013 Under the guidance of: Prof. Lawrence Chung University of Texas at Dallas](https://reader036.vdocuments.us/reader036/viewer/2022081516/56649e175503460f94b02f78/html5/thumbnails/11.jpg)
Grouping, natural phenomenon
• ORIs it self-occurring that we simply want to understand?

Influences: Group, Relation
Key Influences to consider:
Environment:- It has effect on objects, relations and group. - It is not just about the individual object. The same objects can interact differently in different environment.
Change in objects and relation:- Both object and relation may change.- Change can evolve or be sudden.
History:- Road looks narrow in the distance for a reason.

Group Examples
• Other examples:- biological protein categories- chemical types- politics: campaign- data science: big data- countries: economic blocs- sports: team formation- etc
![Page 15: Model: Relations and Groups Prabin Gautam CS/SE 6361, Fall 2013 Under the guidance of: Prof. Lawrence Chung University of Texas at Dallas](https://reader036.vdocuments.us/reader036/viewer/2022081516/56649e175503460f94b02f78/html5/thumbnails/15.jpg)
Importance
Why is it important establish, predict relation or form group?
- Sound decisions are made based on correct relation analysis.- Easier information processing.- Pattern recognition.- Just for making sense, getting gist.- Extracting valuable info from a big data.- etc.
![Page 16: Model: Relations and Groups Prabin Gautam CS/SE 6361, Fall 2013 Under the guidance of: Prof. Lawrence Chung University of Texas at Dallas](https://reader036.vdocuments.us/reader036/viewer/2022081516/56649e175503460f94b02f78/html5/thumbnails/16.jpg)
As is
- Lack of basic and general purpose model, that helps with relation establishment and prediction,forming groups and subgroups from set of objects
- Each field has their own methods
- Too simple methods, like grouping by few categories at a time, such as frequency is not enough. In addition to having common group features, It should analyze how new a member fits in with other members, subgroups with in a group.What is the threshold for inclusion?etc
![Page 17: Model: Relations and Groups Prabin Gautam CS/SE 6361, Fall 2013 Under the guidance of: Prof. Lawrence Chung University of Texas at Dallas](https://reader036.vdocuments.us/reader036/viewer/2022081516/56649e175503460f94b02f78/html5/thumbnails/17.jpg)
To be
. Functional Objectives- Basic general purpose model.- Model that can be expanded for specialization.- Model that can be expanded for new knowledge.- Multidimensional model, that takes external influences into account.- Model that includes individual, individual-group, group-group relationship dynamics into account in group formation.- Model that learns from and helps understand natural phenomenon in a cycle.
. Non functional Objectives- Simplicity- Adaptability- Extendibility- etc
