How to Write an Expert Systems with Applications Cover Letter (Template)

The order matters. ESWA editors scan for application signal density, not literary polish. A letter that names the application, the contribution, the fit, and the declaration in that sequence routes faster than one that opens with three sentences of literature context.

The opening sentence either signals an application paper or it does not. ESWA editors can tell within one line whether you understand the venue.

Weak opener:

"In this paper we propose a novel deep learning model and evaluate it on a benchmark dataset."

Why it fails: no application domain, no real setting, no consequence, and it reads as a methods note that belongs at a pattern-recognition or pure-ML venue.

Strong opener:

"We present an intelligent fault-diagnosis system deployed on production-line sensor streams in a manufacturing setting, and we show it reduces unplanned-downtime false alarms by a measurable margin against the current rule-based baseline."

Why it works: the application domain is concrete, the system has a real setting, the comparison is to a deployed baseline, and the editor can already see why this is an ESWA paper rather than a generic model paper.

ESWA's primary article type is the Research Paper, and the journal does not run a separate short-communication or brief-report format. So name the type plainly in the first line. The two cases worth distinguishing in the letter:

• Research Paper. The default. State it, then make the application-fit argument. ESWA Research Papers typically present a system applied and validated in a real domain.

• Review Article. If you are submitting a survey rather than primary research, say so in the opening sentence so the editor screens it against review-article expectations (coverage, taxonomy, field synthesis) rather than primary-research expectations (baselines, ablations, reproducibility).

If your contribution is too brief to stand as a full Research Paper, expand it or route it to a sibling venue rather than forcing a short format ESWA does not offer.

This is where ESWA differs from many cover-letter guides, and it is a genuine source of confusion. Elsevier's official support guidance says the cover letter should not include funding information, author declarations, or suggested reviewers, because Editorial Manager requests these in separate, structured steps. Elsevier's author-education guidance, however, recommends including the originality and conflict declarations in the letter itself. Both are Elsevier sources.

The practical reconciliation: complete the dedicated Editorial Manager fields (declarations, funding, CRediT contribution statement, data availability, preferred and opposed reviewers), and also state the originality and all-authors-approved lines in the cover letter as a courtesy and a fail-safe. Editors read the letter first; a clean declaration there signals a carefully prepared package.

The verbatim declaration to include:

This manuscript is original, has not been published previously, and is not under consideration for publication elsewhere. All authors have read and approved the submitted version and agree to its submission.

On suggested reviewers specifically: Editorial Manager provides preferred-reviewer and opposed-reviewer fields. Provide 2 to 4 reviewers with genuine expertise in your application domain and method. Exclude reviewers who are recent co-authors, current or former advisors, same-institution colleagues, or anyone with a funding or commercial tie. Do not pad the list, and do not repeat it in the cover letter unless the submission system lacks a reviewer field.

On preprints: ESWA permits posting a preprint, but disclose any preprint link in the submission so the editor can see the prior-posting context. On competing interests and funding: declare them in the structured Editorial Manager step and the manuscript's declarations section, even when there are none to report.

When we read an ESWA-bound cover letter the way a handling editor would, we are not scanning for politeness. We read the first two sentences to answer one question: is there a real application here, or is this a model paper wearing an application label? If the opening names a domain, a setting, and a comparison to a current baseline, we keep reading.

If it opens with "we propose a novel architecture," we have already started routing the paper toward a desk decision or a transfer suggestion. The letter that earns review is the one that lets the editor route the paper without opening the manuscript file first.

In our pre-submission review work with Expert Systems with Applications submissions, the cover letter fails in three patterns that show up before the editor opens the manuscript file, and each one is fixable in a single revision pass. Each is a specific, named failure pattern you can check your own draft against, and each reflects the editorial culture of an application journal rather than a generic methods venue.

The model-first opener that hides the application. In our analysis of ESWA-bound letters, the most common pattern we see is an opening sentence built around the method ("we propose a novel transformer variant") with the application domain demoted to a subordinate clause or omitted entirely. We observe that letters with this opener draw faster desk decisions, because editors routinely screen for application context in the first line.

ESWA is an application journal, so this framing reads as a methods note routed to the wrong venue. We rewrite the opener so the application domain and real setting lead and the model is the enabler. The fix is mechanical: the first sentence of the cover letter should name the domain, the setting, and the consequence, and the abstract's first sentence should match it.

When the cover letter and abstract both lead with the application, the desk-screen risk drops sharply.

The benchmarks claim with no fair-comparison signal. ESWA reviewers are instructed to weight whether the comparison set is fair and whether the result is independently checkable, far more than whether the idea is new. We repeatedly see cover letters that assert state-of-the-art results without naming a single current baseline or acknowledging the comparison conditions.

A handling editor reading that letter cannot tell whether the benchmarks are fair, so the safest editorial move is a revision request or a desk decision. We add one sentence naming the current baselines the paper beats and the dataset or deployment setting, which converts an unverifiable claim into a checkable one and signals that the benchmark table will hold up under review.

The missing reproducibility and declaration signals. Across ESWA submissions we pre-screen, the letters that draw the cleanest first decisions reference downloadable reproducibility artifacts (code and data) and carry the originality and all-authors-approved declarations plainly. The letters that stall omit both: no mention of a code or data archive, and no non-duplication declaration, which forces the editor to chase the structured Editorial Manager fields to confirm the submission is complete.

We add a one-line reproducibility reference and the verbatim originality declaration, because ESWA's data-availability expectation and double-anonymized review mean a reproducibility-aware, declaration-complete package reads as a carefully prepared submission rather than a hopeful upload. A complete declaration set in the letter is the cheapest trust signal available before review.

These three patterns are why we treat the ESWA cover letter, the abstract's first sentence, the benchmark table, the reproducibility files, and the declarations as one editorial intake package rather than separate documents. A ESWA cover letter and benchmark-framing check evaluates application-fit signal and citation integrity before you submit.
