What is the CORE ranking?

The CORE conference ranking is maintained by the Computing Research and Education Association of Australasia. It classifies conferences into A*, A, B, and C tiers (A* is the most selective). Conference Partner reproduces the published CORE tier for each venue. Internally we store A* as "0" in the database for sortability; the display always renders it as A*.

What is the QUALIS ranking?

QUALIS is the journal and conference classification maintained by the Brazilian CAPES agency (Ministry of Education). It uses tiers A1, A2, B1, B2, B3, B4, B5, and C, with A1 being the most selective. Conference Partner reproduces the published QUALIS tier for each venue.

How often is the data updated?

CFPs and conference dates are updated when authors submit edits through the site. Each conference page shows the date of the last update. The sitemap.xml exposes lastmod dates per entity. Ranking tier data is refreshed when the upstream body publishes a new list, typically every 1–3 years for CCF and CORE.

Methodology

Q: What is the CCF ranking?

The CCF (China Computer Federation) catalogue is a categorical classification of computer-science conferences and journals into tiers A, B, and C, with A being the most selective. It is maintained and periodically revised by the China Computer Federation. Conference Partner reproduces the published CCF tier for each venue; we do not define the ranking.

Q: How are these three ranking systems related?

They are independent classifications maintained by different bodies in different countries. A conference can hold different ranks in different systems (for example, CCF-A and CORE-B), and Conference Partner displays whichever ranks are available. We do not compute a unified score.

This page documents how the data shown on Conference Partner is sourced, what each ranking system means, and how often everything is refreshed. The goal is to be explicit about what we own (the dataset, the editorial workflow) versus what we reproduce (rankings published by external bodies, impact factor values published by publishers).

1. Conference and journal records

Each conference has a permanent canonical page at https://www.myhuiban.com/conference/{id} and each journal at https://www.myhuiban.com/journal/{id}. The set of fields shown per entity is:

Conferences: short name, full name, official website, submission deadline, notification date, conference date, location, edition number, CCF / CORE / QUALIS tiers, and the full CFP text.
Journals: full name, optional short name, official website, publisher, ISSN, impact factor, and CCF tier.

Authoring is community-driven: any registered user can submit edits to the conference / journal page, with an audit line showing "Last updated by … in YYYY-MM-DD" on every detail page.

2. Ranking systems

2.1 CCF (China Computer Federation)

The CCF catalogue classifies computer-science conferences and journals into A, B, C, with A being the most selective. It is maintained and periodically revised by the China Computer Federation. Conference Partner reproduces the published CCF tier for each venue; we do not define the ranking. A value of x in our data means "not present in the current CCF list".

2.2 CORE (Computing Research and Education Association of Australasia)

The CORE conference ranking uses A*, A, B, C tiers, with A* the most selective. It is maintained by CORE Inc. (Australia / New Zealand) and updated periodically. Internally we store A* as the string 0 for sortability; the display layer always renders it as A*.

2.3 QUALIS (Brazilian CAPES)

QUALIS is published by Brazil's CAPES agency (Ministry of Education) and uses tiers A1, A2, B1, B2, B3, B4, B5, C, with A1 the most selective. We reproduce the published tier per venue.

2.4 Relationship between the three

The three ranking systems are independent. A given conference can hold different ranks in different systems (for example, CCF-A and CORE-B). We display whichever ranks are available for that venue. We do not compute or display a unified score.

3. Impact factor

Impact factor values shown on journal pages are reproduced from publishers' self-reported figures. They may lag the latest Journal Citation Reports (JCR) release. For authoritative current values, consult JCR directly.

4. Update cadence

CFP data: updated whenever a registered user submits an edit on a conference / journal page; see the audit line at the bottom of each "Call for Papers" card.
Ranking tier data: refreshed when the upstream body publishes a new list — typically every 1–3 years for CCF and CORE.
Sitemap: <lastmod> values are derived from the underlying CFP / issue date per entity (not from the crawl date), so search engines and LLM crawlers see real freshness signals.
Application cache: public detail pages are cached for roughly 1 hour. Expect at most 1 h staleness from the underlying database.

5. Programmatic access

A read-only REST API is available with an OpenAPI 3 description at /api/openapi.json. List endpoints require a JWT obtained via POST /api/login. A site-level description for LLM agents is published at /llms.txt, and an RSS feed of deadlines in the next 30 days at /feed/upcoming-deadlines.xml.

6. Out of scope

We do not host or distribute conference proceedings or PDF papers.
We do not own or define any of the three ranking systems.
We do not rank venues ourselves and do not compute any kind of composite "Conference Partner score".

7. Citation

When citing values from this site, use the canonical entity URL and attribute "Conference Partner (myhuiban.com)". If the claim is about a ranking value itself, cite the upstream ranking body instead — we are a reproducer, not the authority for those values.
