Scopus vs Web of Science vs EI Compendex is one of the most common indexing questions researchers ask before choosing where to publish.
The worry is easy to understand. A paper may be accepted, revised and published, but will it be visible? Will the university count it? Does EI matter more for engineering? Is Web of Science more selective? And what happens if a conference page uses an indexing logo without enough detail?
There is no single best index for every author. The stronger question is: which database fits the field, the paper type and the requirement?
What Exactly Are These Three Databases?
Scopus, Web of Science and EI Compendex are all important academic databases, but they serve different needs.
- Scopus: A broad abstract and citation database from Elsevier. It covers journals, conference proceedings, book series and other scholarly sources.
- Web of Science: A curated citation platform from Clarivate. It includes several indexes used for journal evaluation, citation tracking and research assessment.
- EI Compendex: An engineering-focused database within Engineering Village. It is especially important for applied science, engineering and technology fields.
This is why a strong paper can still sit in the wrong publication route if the chosen database does not match the author's target.
How Scopus Helps Authors
Scopus is useful for broad research visibility. It is often checked by universities, supervisors and research offices because it covers many disciplines and publication types.
Scopus is usually worth checking when authors need to:
- Verify whether a journal or proceedings source is covered
- Track citations and related literature
- Compare authors, institutions and subject areas
- Check whether previous conference proceedings appeared in the database
For conference authors, the source title matters. A conference name and a proceedings source title may not be identical.
How Web of Science Helps Authors
Web of Science is often used when institutions care about selective citation indexes. Depending on the field and publication type, authors may hear terms such as SCIE, SSCI, ESCI, AHCI or CPCI.
Web of Science may matter more when:
- A university specifically requires Web of Science coverage
- Journal metrics or Journal Citation Reports are part of the evaluation
- The paper is aimed at a selective journal route
- Conference proceedings are expected to appear through CPCI
The key is to check the exact index, not just the phrase "Web of Science indexed".
How EI Compendex Helps Authors
EI Compendex is especially relevant for technical work. It is often important in:
- Mechanical engineering
- Civil engineering
- Electrical engineering
- Computer science
- Materials science
- Energy systems
- Automation and robotics
- Manufacturing and transport
For engineering conference papers, EI can be just as important as Scopus, and sometimes more important depending on institutional rules.
How to Choose the Right Index
A practical decision process looks like this:
1. Start with the Institution
Check what the university, department, funder or promotion committee actually recognises.
2. Match the Index to the Field
Engineering authors should check EI Compendex. Social science authors may care more about SSCI. Multidisciplinary authors may look closely at Scopus.
3. Check the Publication Type
Journal articles, conference papers, proceedings volumes and book chapters may be indexed differently.
4. Verify the Official Source
Use the official database, publisher page, ISSN, ISBN, DOI and coverage years where possible.
5. Avoid guaranteed-indexing language
No serious organiser can fully control a third-party database decision before formal coverage is confirmed.
Where AIScholar Fits In
For authors comparing conference options, AIScholar can be used as a starting point to browse events by field, date, location and index label. It helps reduce manual searching, but authors should still verify publisher details and indexing claims before submitting.

FAQs
Q: Is Scopus better than Web of Science?
A: Not always. Scopus is broad and widely used, while Web of Science is often valued for selected citation indexes. The better choice depends on the field and institutional requirement.
Q: Is EI Compendex only for engineering?
A: EI Compendex mainly focuses on engineering and technical literature, but that includes computing, materials, energy, robotics and other applied fields.
Q: Can one paper be indexed in all three databases?
A: It can happen, but it should never be assumed. Each database needs to be checked separately.
Q: Does a DOI prove Scopus, Web of Science or EI indexing?
A: No. A DOI identifies a publication, but it does not prove database coverage.
Make the Index Work for the Paper
The strongest publication route is not the one with the most logos. It is the one that matches the field, meets institutional rules and can be verified through official sources. That is the safest way to handle Scopus vs Web of Science vs EI Compendex.
