Journal Rank Local by Luluya

Journal Rank Local 是一款面向科研用户的浏览器扩展，在学术网页上自动识别期刊，并就地显示影响因子、分区与收录信息。

网站专门适配，本地优先识别
针对多个主流学术平台的页面结构专门适配，更准确地定位期刊来源，减少参考文献、推荐内容等无关信息的干扰。优先使用本地期刊数据库完成匹配，减少无关扫描与不必要的联网查询。

期刊指标与收录
- JCR：影响因子、JCR 分区
- 中科院分区
- 北大核心
- CSSCI（含扩展版）
- CCF 推荐目录
- 浙大期刊分级
- 中国科技核心（仅在知网页面显示）
- EI Compendex 来源期刊
每项来源均可在弹窗中单独开启或关闭，弹窗同时显示各数据的版本。EI 徽标仅表示期刊属于 EI Compendex 来源目录，不代表当前文章已被 EI 收录。

内置支持的网站
学术检索与文献平台：Google Scholar、Web of Science、PubMed / PMC、中国知网（CNKI）、ResearchGate、ACL Anthology；另支持手动授权后的 Gmail Google Scholar 快讯。
出版社与期刊平台：ScienceDirect、Cell Press、The Lancet、Springer / SpringerLink、Nature、Wiley、Taylor & Francis、SAGE、Oxford Academic、Cambridge Core、IEEE Xplore、ACM Digital Library、Science / AAAS、JAMA Network、BMJ、Frontiers、MDPI、JSTOR、Brill、De Gruyter / De Gruyter Brill、APA PsycNet / APA Journals、ACS Publications、RSC Publishing、Royal Society Publishing、APS Journals、IOPscience、PLOS、PNAS、Emerald Insight、AEA、INFORMS PubsOnLine、Academy of Management、Annual Reviews、Project MUSE、MIT Press Direct、John Benjamins / JBE Platform、Edinburgh University Press。
支持范围因网站和页面类型而异；是否显示还取决于页面信息是否足以确认期刊身份，以及期刊是否收录于本地数据库。
其他网站可在弹窗中授权当前网站后尝试识别，效果取决于页面提供的期刊信息。

主要功能
- 按 ISSN、页面元数据、标准刊名和确定性链接识别期刊；证据冲突或无法确定时不显示，尽量避免误标。
- Google Scholar 搜索与 Gmail Scholar 快讯可分别开启期刊结果过滤（默认关闭）；可选择仅显示可识别的期刊结果，并控制是否保留未确定项（默认保留）。
- 弹窗可随时暂停或恢复当前页面的显示。
- Gmail 默认不运行，需用户手动授权；仅处理 Google Scholar 快讯，不扫描普通邮件。

隐私
期刊等级数据全部内置在扩展中，优先在浏览器本地完成匹配，不上传完整网页内容，不收集用户数据。
仅当本地无法识别某篇论文所属期刊时，扩展才会按需使用该论文公开的标识符（如 DOI、PII、PMID 或 APA 记录号）查询 Crossref、NCBI 等公共元数据服务，或读取已授权出版社落地页的有限 HTML 头部，以获取期刊 ISSN 和刊名。
Google Scholar 搜索与 Gmail Scholar 快讯在上述途径仍无法识别时，还可能使用公开文章标题查询 Crossref。
这些元数据请求不携带 Cookie 或来源页信息；第三方服务仍会收到所查询的公开标识符或标题及连接 IP。具体处理方式见隐私政策。

Journal Rank Local helps researchers see journal metrics and indexing information directly on academic webpages. It automatically identifies journals and displays badges in place.

Site-specific support, local-first matching
Tailored to the page structures of major academic platforms, the extension locates journal information more precisely and reduces interference from references, recommendations, and other unrelated content. It prioritizes matching against its local journal database to reduce unnecessary scanning and network requests.

Metrics and catalogs
- JCR: Impact Factor and JCR quartile
- CAS (Chinese Academy of Sciences) journal ranking
- Peking University Core Journals
- CSSCI (including the extended list)
- CCF Recommended List
- Zhejiang University journal classification
- China Science and Technology Core Journals (displayed on CNKI pages only)
- EI Compendex source journals
Each source can be turned on or off individually in the popup, which also shows the version of each dataset. The EI badge indicates that a journal is listed as an EI Compendex source; it does not mean that the current article is indexed in Compendex.

Built-in sites
Academic search and literature platforms: Google Scholar, Web of Science, PubMed / PMC, CNKI, ResearchGate, and ACL Anthology. Google Scholar alerts in Gmail are also supported after you grant permission.
Publishers and journal platforms: ScienceDirect, Cell Press, The Lancet, Springer / SpringerLink, Nature, Wiley, Taylor & Francis, SAGE, Oxford Academic, Cambridge Core, IEEE Xplore, ACM Digital Library, Science / AAAS, JAMA Network, BMJ, Frontiers, MDPI, JSTOR, Brill, De Gruyter / De Gruyter Brill, APA PsycNet / APA Journals, ACS Publications, RSC Publishing, Royal Society Publishing, APS Journals, IOPscience, PLOS, PNAS, Emerald Insight, AEA, INFORMS PubsOnLine, Academy of Management, Annual Reviews, Project MUSE, MIT Press Direct, John Benjamins / JBE Platform, and Edinburgh University Press.
Supported page types vary by site. Badges also depend on sufficient evidence to identify the journal and its inclusion in the local database.
You can grant access to other sites from the popup to try journal recognition; results depend on the journal information available on the page.

Key features
- Identifies journals using ISSNs, page metadata, standard journal titles, and deterministic URLs. No badge is shown when evidence conflicts or is uncertain, helping avoid incorrect labels.
- Separate optional journal-result filters for Google Scholar search and Gmail Scholar alerts (off by default). You can select recognized journal results and choose whether to retain uncertain items (retained by default).
- Pause or resume badges on the current page at any time.
- Gmail access is off by default and requires explicit permission. Only Google Scholar alerts are processed; ordinary emails are not scanned.

Privacy
All journal ranking data is bundled with the extension, and matching is performed locally whenever possible. The extension does not upload complete webpage content or collect user data.
Only when a paper’s journal cannot be identified locally does the extension use its public identifiers, such as DOI, PII, PMID, or APA record ID, to query public metadata services such as Crossref and NCBI, or read a limited portion of an authorized publisher landing page’s HTML head to obtain the journal ISSN and title.
For Google Scholar search and Gmail Scholar alerts, a public article title may also be queried through Crossref if those methods are unsuccessful.
These metadata requests include no cookies or referrer information. Third-party services still receive the queried public identifiers or titles and the connection IP address. See the privacy policy for details.
