Writing a Science or Engineering Paper: It is just a story Frank Shipman Department of Computer Science Texas A&M University

Scientific Writing as Storytelling What is the goal of science / engineering? –To answer questions of what, where, when how, and who. –To convey these answers to others. But how do we convince others of our results?

Convincing Results Different fields use different (primary) methods for generating and evaluating the validity of results. –Proofs in mathematics –Statistics in psychology –Grounded observation in anthropology –Precise argument in the humanities

But it all comes down to … Why do we care about the proof? Why do we believe the interpretation of the statistics or observations? Why do we believe the humanities argument? Storytelling

Not a Derogatory Term Storytelling frequently is used as a derogatory term indicating the presentation of untruths. But in the end it is the story that you tell about the proof, the statistics, the observations, or the argument that will make your results convincing.

Telling a Good Scientific Story Have a protagonist –a user trying to accomplish something, something your audience cares about –in some cases the protagonist is implicit Examples –the person using the network or computer to make decisions (scheduling deliveries, deciding on investments) –the person performing a task with computer support (landing a broken airplane, teaching a class, etc.)

Telling a Good Scientific Story Have a villain –the problem that threatens to keep the protagonist from accomplishing their goals –the problem should be real in order to keep your reader’s attention Examples –an insurmountable amount of information –an unpredictable communication channel –a limited amount of human attention, etc.

Telling a Good Scientific Story Have a plot –an approach for the protagonist to win out over the villain (solving the problem) –this is the hypothesis and contribution –it can be very focused or very big Examples –an algorithm for dealing with more data –a new flight-control system for pilots

Telling a Good Scientific Story Have a full and rich backdrop –stories must happen in “believable” settings – consistency is a must –stories are rarely simple, there are other stories that interact with the main one Examples –Related work and prior results –Details of the setting –Interactions with other systems and solutions that the protagonist may be using

Telling a Good Scientific Story Have a strong finale –have an answer about the outcome of the story (is the protagonist’s problem solved?) –good stories do not always have happy endings Examples –The algorithm locates (or not) information that lets the decision be made –The system makes (or not) the person’s task more efficient, more accurate, or more satisfying.

The (Idealized) Outline Introduction and Problem Statement –The protagonist and antagonist Approach –The plot Related and prior work, design and implementation –The setting Evaluation results and interpretation –The finale

Finale When writing reports, don’t just describe what you did. Describe why you did it. Describe how it compared to other options. Describe what did and did not work.

My Finale Computer science is a new field, relative to other disciplines like physics, that answers a variety of questions: –What can be computed using what resources? –What problems can be solved using computers? To answer these questions, methods are borrowed from a number of disciplines. It needs researchers that can author and recognize good stories regardless of the particular methodology.
