How to write a great research paper Simon Peyton Jones Microsoft Research, CambridgeWhy bother Fallacy Good papers and we write papers and talks are a give talks mainly to impress others, gain fundamental recognition, and get promoted part of research excellence„„ Papers communicate ideas Your goal: to infect the mind of your reader with your idea, like a virus Papers are far more durable than programs (think Mozart) The greatest ideas are (literally) worthless if you keep them to yourselfWriting papers: model 1 Idea Do research Write paper„„„ Writing papers: model 2 Idea Do research Write paper Idea Write paper Do research Forces us to be clear, focused Crystallises what we don’t understand Opens the way to dialogue with others: reality check, critique, and collaborationDo not be intimidated Fallacy You need to have a fantastic idea before you can write a paper or give a talk. (Everyone else seems to.) Write a paper, and give a talk, about any idea, no matter how weedy and insignificant it may seem to you„„ Do not be intimidated Write a paper, and give a talk, about any idea, no matter how insignificant it may seem to you Writing the paper is how you develop the idea in the first place It usually turns out to be more interesting and challenging that it seemed at firstThe purpose of your paperThe purpose of your paper is... To convey your idea ...from your head to your reader’s head Everything serves this single goalƒƒ The purpose of your paper is not... To describe the WizWoz system Your reader does not have a WizWoz She is primarily interested in reusable brainstuff, not executable artefacts„„„„„„ I wish I Conveying the idea knew how to solve that Here is a problem It’s an interesting problem I see how It’s an unsolved problem that works. Ingenious Here is my idea My idea works (details, data) Here’s how my idea compares to other people’s approaches„„„„„„„ Structure Abstract (4 sentences) Introduction (1 page) The problem (1 page) My idea (2 pages) The details (5 pages) Related work (12 pages) Conclusions and further work (0.5 pages)„„„ The abstract I usually write the abstract last Used by program committee members to decide which papers to read Four sentences Kent Beck 1. State the problem 2. Say why it’s an interesting problem 3. Say what your solution achieves 4. Say what follows from your solutionExample 1. Many papers are badly written and hard to understand 2. This is a pity, because their good ideas may go unappreciated 3. Following simple guidelines can dramatically improve the quality of your papers 4. Your work will be used more, and the feedback you get from others will in turn improve your research„„„„„„„ Structure Abstract (4 sentences) Introduction (1 page) The problem (1 page) My idea (2 pages) The details (5 pages) Related work (12 pages) Conclusions and further work (0.5 pages)The introduction (1 page) 1. Describe the problem 2. State your contributions ...and that is allDescribe the problem Use an example to introduce the problem„„„ State your contributions Write the list of contributions first The list of contributions drives the entire paper: the paper substantiates the claims you have made Reader thinks “gosh, if they can really deliver this, that’s be exciting; I’d better read on”State your contributions Bulleted list of contributions Do not leave the reader to guess what your contributions areContributions should be refutable We describe the WizWoz We give the syntax and semantics of system. It is really cool. a language that supports concurrent processes (Section 3). Its innovative features are... We study its properties We prove that the type system is sound, and that type checking is decidable (Section 4) We have used WizWoz in We have built a GUI toolkit in practice WizWoz, and used it to implement a text editor (Section 5). The result is half the length of the Java version.„„ No “rest of this paper is...” “The rest of this paper is structured as Not: follows. Section 2 introduces the problem. Section 3 ... Finally, Section 8 concludes”. Instead, use forward references from the narrative in the introduction. The introduction (including the contributions) should survey the whole paper, and therefore forward reference every important part.„„„„„„„ Structure Abstract (4 sentences) Introduction (1 page) The problem (1 page) My idea (2 pages) The details (5 pages) Related work (12 pages) Conclusions and further work (0.5 pages)No related work yet Related work Your reader Your idea We adopt the notion of transaction from Brown 1, as modified for distributed systems by White 2, using the fourphase interpolation algorithm of Green 3. Our work differs from White in our advanced revocation protocol, which deals with the case of priority inversion as described by Yellow 4.„„ No related work yet I feel Problem 1: describing tired alternative approaches gets between the reader and your idea Problem 2: the reader knows nothing about the problem yet; so your (carefully trimmed) I feel description of various technical stupid tradeoffs is absolutely incomprehensible„„„ Instead... Concentrate singlemindedly on a narrative that Describes the problem, and why it is interesting Describes your idea Defends your idea, showing how it solves the problem, and filling out the details On the way, cite relevant work in passing, but defer discussion to the endƒƒƒ The payload of your paper Consider a bufircuated semilattice D, over a hyper modulated signature S. Suppose pi is an element of D. Then we know for every such p there is an epimodulus i j, such that p p . j i Sounds impressive...but Sends readers to sleep In a paper you MUST provide the details, but FIRST convey the ideaThe payload of your paper Introduce the problem, and your idea, using EXAMPLES and only then present the general caseThe Simon PJ question: is there Using examples any typewriter font Example right away„„„„ Conveying the idea Explain it as if you were speaking to someone using a whiteboard Conveying the intuition is primary, not secondary Once your reader has the intuition, she can follow the details (but not vice versa) Even if she skips the details, she still takes away something valuable„„„„ Evidence Your introduction makes claims The body of the paper provides evidence to support each claim Check each claim in the introduction, identify the evidence, and forward reference it from the claim Evidence can be: analysis and comparison, theorems, measurements, case studies„„„„„„„ Structure Abstract (4 sentences) Introduction (1 page) The problem (1 page) My idea (2 pages) The details (5 pages) Related work (12 pages) Conclusions and further work (0.5 pages)Related work Fallacy To make my work look good, I have to make other people’s work look badƒƒƒ The truth: credit is not like money Giving credit to others does not diminish the credit you get from your paper Warmly acknowledge people who have helped you Be generous to the competition. “In his inspiring paper Foo98 Foogle shows.... We develop his foundation in the following ways...” Acknowledge weaknesses in your approachƒƒ Credit is not like money Failing to give credit to others can kill your paper If you imply that an idea is yours, and the referee knows it is not, then either You don’t know that it’s an old idea (bad) You do know, but are pretending it’s yours (very bad)„„„ Making sure related work is accurate A good plan: when you think you are done, send the draft to the competition saying “could you help me ensure that I describe your work fairly”. Often they will respond with helpful critique They are likely to be your referees anyway, so getting their comments up front is jolly good.„„ „„„ The process Start early. Very early. Hastilywritten papers get rejected. Papers are like wine: they need time to mature Collaborate Use CVS to support collaboration„„„„ Getting help Get your paper read by as many friendly guinea pigs as possible Experts are good Nonexperts are also very good Each reader can only read your paper for the first time once So use them carefully Explain carefully what you want (“I got lost here” is much more important than “wibble is misspelt”.)Listening to your reviewers Every review is gold dust Be (truly) grateful for criticism as well as praise This is really, really, really hard But it’s really, really, really, really, really, really important„„„ Listening to your reviewers Read every criticism as a positive suggestion for something you could explain more clearly DO NOT respond “you stupid person, I meant X”. Fix the paper so that X is apparent even to the stupidest reader. Thank them warmly. They have given up their time for you.Language and style„„„ „„„ Basic stuff Submit by the deadline Keep to the length restrictions Do not narrow the margins Do not use 6pt font On occasion, supply supporting evidence (e.g. experimental data, or a writtenout proof) in an appendix Always use a spell checker„„„„ „„ Visual structure Give strong visual structure to your paper using sections and subsections bullets italics laidout code Find out how to draw pictures, and use themVisual structureUse the active voice The passive voice is “respectable” but it DEADENS your paper. Avoid it at all costs. “We” = you and the NO YES reader It can be seen that... We can see that... 34 tests were run We ran 34 tests These properties were We wanted to retain these thought desirable properties “We” = the authors It might be thought that You might think this would this would be a type error be a type error “You” = the readerUse simple, direct language NO YES The object under study was The ball moved sideways displaced horizontally On an annual basis Yearly Endeavour to ascertain Find out It could be considered that the The garbage collector was really speed of storage reclamation slow left something to be desired„„„ Summary If you remember nothing else: Identify your key idea Make your contributions explicit Use examples A good starting point: “Advice on Research and Writing” http://www2.cs.cmu.edu/afs/cs.cmu.edu/user/ mleone/web/howto.html
