Published:
This is a note on how to do science reading, writing, and presentation.
Scientific Reading, Writing and Presenting 1
Literature Search
How do I find relevant literature?
If you don’t have a starting point (paper) yet, use keyword based search
If you found an interesting paper, you can use forward and backward search
- For finding new papers that cite this paper, click the “Cited by” on Google Scholar
- For finding older papers cited by a paper, read related work section (references)
Use online tools
- Connected Papers
- Research Rabbit
- Find author’s homepage and check their publications
Is a paper worth reading?
- In general, it’s difficult to say before reading
- You must invest time, it’s a hard work
How do I organize my literature?
Citation and reference management software
- JabRef (offline)
- Mendeley (offline / online)
- Zotero (offline / online)
Scientific Reading
How to read a paper?
- Unless 100% sure the paper is relevant, don’t read it linearly from start to end
- Instead, take a quick look at abstract, contributions, teaser, results (~ 10 min)
- Take notes, summarize and decide if you want to read it in depth (~ 2h)
Keep notes
- Highlight important passages
- Add comments, take notes
- Mark what you did understand and what you didn’t
- Summarize in your own words
Understand the content deeply
- Look up unknown concepts
- Read prior work if necessary
Scientific Writing and Reviewing
How to write a report?
Start early and iterate
- Writing needs time
- Ideas form while writing
- Problems surface while writing
- It’s important to start writing early on and iterate
- Start with a longer text and shorten it later
- Be inspired by the papers you read, adopt good writing styles
- Make sure language and grammar are correct, avoid colloquial language (use tools like Grammarly for finding and fixing typos)
Come up with a good structure
- Abstract - Motivation and key messages? (200-400 words)
- Introduction - What is the problem? Where does it occur?
- Motivation - Why should we care? What applications?
- Background - Which background knowledge is necessary?
- Approach - How does it work? How do different methods compare?
- Results – What has been achieved? What works and what doesn’t? Why?
- Summary – What should we have learned? Future work?
- References – Use the \cite command
Follow good scientific practice
- Your text should be your own exposition and explain things in your words
- Don’t copy sentences 1:1 from your sources (unusual in natural science)
- Whenever stating a fact that is known, add the corresponding citations
- Make sure all related work is cited appropriately (otherwise: plagiarism)
- Citations are added before punctuation marks
- Use Latex in combination with Bibtex to manage your citations and bibliography
- Use the cite package to format the bibliography alphabetically
Figures help understanding
- Place figure outside running text, usually at top of page
- Adjust font size to font size of main text
- Caption should describe figure concisely to be understood stand-alone
- When using a figure or table from another source, cite the source in the caption
- Make sure all figures and tables are referenced from the main text
- You can reference the same figure or table multiple times
What is a review?
Reviews are a core element of the scientific process
- Provide feedback to the authors prior to publication, including: Language, clarity, math, rigor, references, experiments (and novelty)
- They serve to improve the manuscript ⇒ make concrete suggestions
- Reviews are objective and state both pros and cons
- Reviews judge the quality of a paper and if it gets accepted
- Area chairs / associate editors make final decision based on reviews
- Often the authors and reviewers don’t know each other (double blind)
- Sometimes the reviewers can see the author’s names (single blind)
Your review provides value
- What is the report about and why is the problem relevant?
- Is the structure of the report appropriate or could it be improved?
- Is the problem description clear? Is it easy to follow?
- Are related works cited appropriately? Are citations missing?
- Are the related works clustered in groups / a taxonomy? Can it be improved?
- Does the report discuss pros and cons of the presented methods?
- Is the problem described formally? Is the math correct? Can it be improved?
- Are all symbols / formulas explained? Common notation? Easy to follow?
- Are the methods well illustrated? If not, what is missing / what can be improved?
- Do the table / figure captions help understanding the tables / figures?
- Is the the language clear and correct? Are there typos?
- Is the experimental setup properly explained?
- Are all utilized datasets, baselines and metrics explained?
- Does the report present qualitative and quantitative results?
- Are the results discussed in an objective manner (pros and cons)?
- Provide both positive and negative feedback, be constructive
Where should I start?
- LaTex is a standard tool for academic typesetting
- Latex allows for professional typesetting of text, formulas, illustration and tables
- Overleaf is an online Latex editor: no installation required, good for beginners
Scientific Presenting
What should I pay attention to?
- Remember that you know more about your subject than anyone else
- Never assume knowledge of your audience
- Pitch your talk such that experts and non-experts (your friend) can understand
- Come up with a good structure
- Introduction – What is the problem? Why should we care? Applications?
- Approach – How does it work? How do different methods compare
- Results – What has been achieved? What works and what doesn’t? Why?
- Summary – What should we have learned? Pros and Cons? Future Work?
- Finalize your talk well in advance
How should I prepare my slides?
- Your story matters
- A common mistake is to create too many slides
- Make sure you spend at least 1 minute per slide (less slides than minutes)
- Keep slides simple and clean to not distract the audience from your message
- Use a simple template, avoid excessive decoration / logos
- Use a large font size
- Use simple and consistent color scheme
- Use a homogeneous background
- Add your name, presentation title and page number to the footline
Focus on the Core Message
- Simplicity is key
- Remember that you can convey only 1 message per slide
- Use maximally 3 bullets per slide, short sentences and simple figures
- Avoid big tables, try to use simple diagrams or bar / pie / curve plots instead
- Highlight important parts of a diagram / illustration as you go through it
- Avoid long text, use keywords instead and explain while presenting
- Your slides should support and illustrate your message, not replace it
- But it is important to explain all baselines / metrics / symbols that you show
- Avoid animations unless important to ease understanding (but then use them)
Language
- Your language matters
- Make sure language and grammar are correct
- Use simple yet precise language
- Avoid colloquial language
- Avoid unnecessary complicated language
- Use tools like Grammarly for finding and fixing typos
Formulas
- Formulas are tough
- Formulas are challenging as they can become complex
- However, they can help to make your message more precise
- Distill the core ideas into the most relevant formulas
- Remove unnecessary symbols (indices, etc.)
- Make sure your notation is consistent across your presentation
- Explain mathematical content slowly and step-by-step
- Show formula side-by-side with a simple example
- Often its easier to understand by example
Which presentation tool should I use?
- Use any tool you get along with (PPT, Beamer, etc.)
How should I practice my talk?
- Practice is everything
- Present your talk to yourself several times before giving the talk
- While practicing, keep track of your time and adjust presentation
- If possible, present to others with no expert knowledge to get feedback
- Avoid using presenter’s notes (and under no circumstances read them)
- Plan your presentation without laser pointer or file cards
- Instead, practice free speech and highlight items directly on the slide
- Show bullets / illustrations one-by-one, highlight key numbers / plots, etc.
What should I do if I get nervous?
- Being nervous is normal
- Adrenaline helps to be present in the moment
- Setup your laptop prior to your session and make sure video / audio works
- Try to remember you first 3 sentences by heart, this helps getting started
- Avoid using presenter’s notes (and under no circumstances read them)
- Instead, practice free speech, every time you will become better
What should I do during the talk?
- Capture your audience
- Keep eye contact with your audience
- Speak slowly, pause from time to time (i.e., after important points)
- Explain the content of every slide, do not leave things out
- Avoid using pointing devices (mouse / laser pointer / hands) too much
- Be excited about the topic that you are presenting (fosters interest)
- Keep track of the time (put a timer, e.g., mobile phone, in front of you)
