Document composition: content assemblage

After having had one-page summaries peer-reviewed and ranked, the organisers asked the speakers to submit a paper of maximum 8 pages, providing a two-column template for IEEE Conference Proceedings. The paper in this record has been created typesetting a LaTeX source code.

Not unusually for conferences, the deadlines catalysed some advancements with respect to the proposed summary. A few findings worth emphasizing were identified while drafting the manuscript. Likewise, composing the text stimulated fresh interpretations; these required additional triaging before being promoted to highlights/insights worth proposing.

Therefore, in order to accommodate for rapid cycles of hypothesis (re)formulation, analysis, (re-)evaluation and incorporation, the first draft was arranged into the canonical sectioning for journal articles in science and technology: Introduction, Methods, Results, Discussion, and Conclusions. These sections provided convenient bins where, based on it anticipated valence, candidate content of varying persistence was routed into. This first round of composition resulted into a 12-page first draft.

Document composition: shortening

The manuscript has then been shrunk to 8 pages interleaving several passes of a three-pronged strategy, aiming at coherence and clarity (the content) as well as at a compact management of the page space (the container).

At the level of sections and paragraphs, coherence was enhanced upon grouping consistent information into single paragraphs and signalling the internal logic with transition words. This also invited reshuffling the canonical sectioning, for example upon splitting the content of the Discussion and moving it into subsections of the Results. While a new structure developed organically, the section titles were renamed altogether to guide the reader directly into restricted topics, as shown in the final table of contents. All these operations made the article more succinct and reduced the space taken without sacrificing the content.

At the level of sentences, clarity was firstly enhanced by simply removing text, images and table parts, whether because of their apparent redundancy or in a kill-your-darlings mode. Making use of the LaTeX way of composing documents, the old text could merely be commented out, conveniently storing old ideas for later re-use. Secondly, tightening up phases and expressions as well as using keywords from specialistic fields in lieu of paraphrases gave additional clarity and conciseness.

Finally, unnecessary empty space was removed upon arranging smaller images in panels and sharing the original-size figures separately as supplementary material; presenting the axis quantities in the figure captions rather than in their labels; and moving supplementary information from the text body to the footnotes. This required some passes of editing and typesetting in order to make sure that the built-in whitespace administration of LaTeX actually produced a visually compact document.

Document composition: release

At the end of this work, the 8-page release candidate underwent a round of final checks of the co-authors', in case linguistic editing had introduced uncertain or unclear statements. This resulted into version 1.1, as published in both the proceedings and Zotero. Residual fixes and improvements --- identified with a fresh pair of eyes after several days of detachment from the document --- have eventually led to a version 1.2. Those versions, each with its own DOI, have been uploaded ahead of the conference and embargoed until its start date. Conveniently, Zenodo also generates a particular DOI that always points to the latest version of the record.

The DOI of this record has been reserved upon creating an unpublished Zenodo entry while drafting the manuscript.The DOI is mentioned in the Acknowledgements to inform the viewers of the possibility to download the paper and its figures after the conference. The publication date is the start date of the conference.
