The Three AspectsThe speaker• body language

– focus • preparedness• voice

– volume– speed– clarity

• nerves • ...

The story• story line• clarity • level• timing• use of terminology• ...

The slides• bullet lists• graphics• fonts• highlights• ...

Effects on you/audience by choices to these?What was helpful to get message across?

Aspect 1: The Storyline

Coursework for Today Make a 1. outline of your presentation

– following our skeleton above – with title slides and – core concepts/slogans per slide

2. list of your terminology – specialist terms that you need in

your presentation

3. suitable running example

‣ Roughly 1 page

Discussion:‣ Pair up with 1 neighbour‣ Discuss for ~5min:‣ storyline‣ list of terms‣ running example

‣ Then swap

‣ Is something ? missing? too long? too short

‣ Is example? big enough? small enough

• Setting the scene: – what kind of problem is addressed?– why is that interesting/relevant?

• Focus: – your Research Hypothesis/Question?

• Methodology/approach/work done: – what have you done/are you doing?

• Context:– how does this relate to other people’s

work? • Contributions made:

– what is the outcome of the work done? – what are the new insights gained? – how do these answer research

hypothesis/question? • Outlook/next steps/open questions?

Aspect 3: Slides for a good presentation

Yes, we’ll discuss Aspect 3 before Aspect 2

Slides for Good Presentations are • pretty

– by being clutter free• clear

– suitable layout & grouping mechanisms– no superfluous ink

• support the story– helpful graphics– main points & keywords

• don’t distract– no complete sentences

Ontology Diffing

pretty - aesthetically pleasing: • helps understanding• attracts interest • raises expectations• makes audience keen to listen

Slides for Good Presentations are

are clear: • serve as handrail for presenter & audience

– contain well-designed graphics to illustrate certain points• should not:

– distract from presenter– confuse

• ... we need to avoid – visual noise– background graphics– un-necessary ink

Slides for Good Presentations

???

Graphics

“a picture can say more than 1,000 words”:• enhances re-call

– amplified under short exposure

…but they need to be done properly:• think of the purpose, message of picture• make sure that this message becomes clear• again, use as little ink as possible

!14

Graphics and Tables

• require a lot of thought & care for choosing– what to display – format (see last slides)– colour - use wisely!– captions, axis titles, etc

• can reader understand what is being shown?– can they read numbers: is 72348765 < 87623458? – how much eye movement & comparison is required?

Good graphics help us remember

• Use good graphics• Repeat them (shrunk) to enhance recall!

Results

• Performance of FFNNs on Task 1

Results

• Performance of RNNs on Task 1

Good examples for using graphics

GroupingGrouping can be done by

• proximity

• color

• region

• connectors

but you should only use 1 of these methods!

Text and Grouping

Bullet lists:• the grouping method for text• make sure grouping

– is logical• items on same level are of the same kind• sub-items related to super item

– is not too deep– has no “lonely” items: these are rarely logical

• (again) minimize ink: avoid duplicating words• no complete sentences/telegram style:

avoid multi-line items like the plague

Ontology• represents

– agreement,– terminology, or– nomenclature

• contains– extensive domain knowledge and/or– known facts/assertions

• is key enabler for semantic metadata extraction from data (un- or semi- or structured)

• plays central role in enabling– resolution of semantic heterogeneity– semantic integration– semantic correlation of objects and documents

Which slide looks clearer?

Fonts

• Choose 1 font for all slides• Careful: projector’s resolution is often poor

– un-serifed (sans serif): serifs are no good on screen– readable: cornet vs comet — dark vs clark vs dork– Arial, Computer Modern Sans, Helvetica, etc.

• Large enough letters

Fonts and Emphasis

• Choose 1 pattern for emphasis and stick to it:– for emphasis: bold or color ...careful: might do the converse!– for new terms/quotes/names: italic– no underlining!– NO CAPITALIZING!

• .... and really stick to it

Animation?

• can be great to– illustrate an algorithm running– show behaviour of example– build up complex picture – ...

• otherwise it creates– useless noise– distraction from speaker

Discuss: making bullet points appearing one-by-one is great!

Which tool to use for your slides?

• Beamer (with Latex)• Latex other • Keynote • Powerpoint• Prezzie• HTML other• something else

My view: Each of these can be used well/badly

Discuss briefly!

Summary: your slides should…

• be clear & pretty – not distracting– not puzzling– not confusing – not making viewers eyes move too much

• contain illustrations to– support your points/findings– help audience understand & remember

Coursework for Tuesday Bring 3-5 of the slides you want to use for your presentation • Ideally some

– with graphics – with texts– you think are good

‣ We will discuss these on Tuesday

the last plenary session

Preview of Aspect 3: Some considerations

regarding the presenter

Clothing & Body Language• Wear something you’re comfortable with when

– many eyes are on you– you’re nervous, sweating

• Talk to the audience– not to the screen, wall, ceiling, lectern,…– show a friendly face, even smile

• Plan what to do with nerves – where to put hands – how/where to stand

• Use your body to make your voice heard– speak to the audience (see above)– stand tall – breath

Making your voice heardTalk• at the right speed

– requires practice & preparation• with breaks so that

– you can breathe– the audience can think

• in an audible way– loud/at the right volume– clear/no mumbling

• following your well thought through narrative – structured in a suitable way– with suitable transitions

• (again) to the audience!

Organisation Part 2

Deliverable 1• during the whole seminar, in particular the discussion

of fellow students’ presentations you• are present• participate actively

Make sure you’ve signed the attendance sheet

During your presentations, we will all give feedback (directly verbally & via those Feedback Notes)

Deliverable 2 • attend all presentations of the Research Symposium • You are assigned 10 presentations; for each

– give a 2-3 sentence summary of its contents and– write a critique: what was good, what could have been better – taking into account all 3 aspects of a presentation

• storyline• slides• presenter

• submit all your summaries and critiques via easychair– your reviews will be anonymous and fed back to presenters– we will discuss these on May 9th

• we’ll clarify this later

In preparation to this, we will email you • from easychair• ask you to become a PC member of UoMRS2019• follow instructions• submit your 10 critiques there

• following the Feedback Notes• these will be shared anonymously with presenters

Deliverable 3• you will give a 15 minute presentation

• about your research (PhD, previous, Tichy study) • to a small group of ~13 fellow participants• we discuss what

• worked well • can be improved

• Later today, we • organise you into groups• start scheduling your presentations

• First presentations: • Thursday, March 21st

You will • attend all and only your group’s presentations in

• ~4 sessions of ~2hours each• give your presentation there

You have received an email from me with • your group (C1, C2, P, U1, U2)• your presentation slot

Coursework for Tuesday Bring 3-5 of the slides you want to use for your presentation • Ideally some

– with graphics – with texts– you think are good

‣ We will discuss these on Tuesday

the last plenary session
