SEIPID Citation Impact Threshold Indices
SEIPID Citation Impact Threshold Indices measure citation impact across a scholarly platform’s registered works. They include the h-index and h5-index, alongside fixed-threshold indices that count how many works have received at least a specified number of citations.
- h-index
- The largest number h for which at least h works have received at least h citations each. An h-index of 8 means that at least eight works have each received eight or more citations.
- h5-index
- The same calculation, restricted to works published during SEIPID’s five-year publication window—the current calendar year and the previous four years.
- Citation threshold indices
- The number of works with citations at or above each threshold: i10: 10+; Seen (س): 25+; Sheen (ش): 50+; Qaf (ق): 100+; Lam (ل): 250+; Meem (م): 500+. For example, a Seen-index of 12 means that 12 works have each received at least 25 citations.
These indices are calculated using all citations, with additional options to exclude platform self-citations, same-author citations, same-organisation citations and same-publisher citations.
Citation Counts & Velocity Metrics
Citation Counts & Velocity Metrics track the citations received by a scholarly platform identified by a NiD or an output identified by a SEIPID. They show total citations, annual and cumulative trends, citations within a selected period, and the rate at which new citations accumulate. These measures update as new citation connections become available.
- Total citations: all recorded citations received.
- Top-cited works: identify the registered outputs with the highest all-time citation counts.
- Citation-source breakdown: compare citation counts and percentages under the SEIPID Registry and SEIPID Rasad source labels.
- Citations by year: citations received in each year.
- Selected-period citations: citations received within the chosen period.
- Cumulative citations: the running citation total over time.
- Citation velocity: the rate of citation accumulation over a defined period.
- Year-on-year change: the increase or decrease compared with the previous year.
- Time to first citation: the interval from an output’s publication to the publication date of its earliest confirmed citing work.
- Citation speed across works: compare the median time to first citation, measured outputs and the share of cited and not-yet-cited works.
Institutional Affiliation & Editorial Board Metrics
Institutional Affiliation & Editorial Board Metrics examine the institutions associated with contributors, editorial board members and registered scholarly works. They show institutional participation, affiliation diversity, concentration and overlap between editorial and publishing communities.
- Institutional participation: explore the registered works associated with contributors from each identified institution.
- Own-organisation authorship share: see the percentage of authorships with recorded affiliations that match the platform’s registered organisation.
- Affiliation coverage: see how many authorships have recorded affiliations out of the total authorships in the selection.
- Affiliation diversity and concentration: understand whether participation is distributed across institutions or concentrated within particular institutions.
- Editorial board affiliations: explore the institutions associated with registered editorial board members.
- Board–author overlap: identify relationships between editorial board membership and authors publishing within a platform.
- Institutional comparisons: compare publication and citation activity across identified institutions within the selected period.
Citation Independence & Network Integrity Metrics
Citation Independence & Network Integrity Metrics examine who cites a scholarly platform or output, the relationships between citing and cited works, and how citations are distributed across the wider network. They explore shared authors, platforms, organisations and publishers, alongside citation independence, concentration and unusual network patterns.
- Who Cited
- Explore citing works, their authors and platforms, and the available citation sources.
- Citation Relationships
- Identify shared platforms, authors, organisations and publishers between citing and cited works. A citation may have more than one identified relationship.
- Citation Independence
- Distinguish citations with identified shared relationships, citations with no identified shared relationship, and cases with insufficient information to determine a relationship.
- Citation Concentration
- Explore how many citations come from particular authors, platforms, organisations or publishers, and their share of the citation total.
- Citing-Publisher Diversity
- Explore how citations are distributed across identified publishers and how much of the citation total comes from particular publishers or publisher groups.
- Reciprocal Citation Patterns
- Examine citation exchange between platforms, including how often platform A cites platform B and platform B cites platform A.
- Network Integrity Patterns
- Explore closely connected groups, ring patterns and unusual citation increases as signals for further review, alongside the diversity and concentration of the citing network.
Readers & AI Usage Metrics
Readers & AI Usage Metrics track recorded interactions with NiD and SEIPID public records, scholarly metadata and SEIPID links. They distinguish human readership from identified AI, search-engine and other automated activity, showing how scholarly records are accessed across different channels and formats over time.
- Readers and automated activity: compare recorded human interactions with AI, search-engine and program activity.
- Reading trends: explore activity over time and within the selected period.
- Activity by format: see recorded access to public pages, supported metadata formats and SEIPID links.
- Audience and discovery sources: explore available reader countries, referring sites and identified automated agents.
- Most viewed works: explore the outputs attracting the most recorded activity within a platform.
Resolution & Link Health Metrics
Resolution & Link Health Metrics describe how SEIPID links are used and whether registered output sources remain reachable. They bring together resolution activity and source-link checks to explain access to the registered source or the output’s public metadata fallback.
- Resolution activity: explore recorded use of SEIPID links by people and automated systems.
- Source-link health: identify links recorded as available, unchecked, unavailable or affected by certificate issues.
- Link checks: review the latest recorded check and available response details to understand the reported status.
- Public metadata fallback: understand how the Registry record remains accessible when an output’s registered source is unavailable or missing.
- Source recovery: follow changes in recorded link health as sources become available again or registered links are updated.

Geographic Reach & Collaboration Metrics
Geographic Reach & Collaboration Metrics examine the geographical reach of a scholarly platform or output through citation origins, readership and research collaboration. They show where research receives attention and how contributors connect across countries and institutions.
- Citing countries: explore the countries from which citations originate, their citation counts and their share of the total.
- Geographical diversity: understand how reach is distributed across countries or concentrated in particular locations.
- Domestic and international collaboration: explore joint publications by contributors within one country or across different countries.
- International collaboration share: see the percentage of outputs involving contributors from more than one known country, calculated across outputs with recorded authorship, alongside the number of outputs used.
- Cross-institution collaboration: identify joint publications involving contributors from different institutions.
- Reach over time: explore changes in geographical reach and collaboration within the selected period.
- Reader geography: explore the available reader-country distribution separately from citation origins.
Collaboration is identified through shared authorship or contribution relationships; citation connections are analysed separately.
Authorship & Contributor Roles Metrics
Authorship & Contributor Roles Metrics examine who contributes to registered scholarly works, how publications are distributed among authors, and the roles contributors perform. They bring together contributor identities, repeat-publication patterns, co-authorship and declared contribution roles.
- Identified authors: count distinct authors identified through the available contributor identifiers and explore their registered works.
- Repeat authors: identify authors with at least two registered outputs within the same platform/NiD in the same calendar year.
- Repeat-author outputs: explore the percentage of outputs associated with repeat authors.
- Identification coverage: see the percentage of recorded authorships linked to confirmed author identities.
- Authorship concentration: explore how publications are distributed among authors, including the most-published authors, their works and their share of platform outputs.
- Co-authorship patterns: explore single-author and multi-author works, team sizes and recurring author groups.
- Authorship countries: explore contributors’ country distribution in a dedicated view.
- Contributor roles: explore registered CRediT roles, such as conceptualisation, methodology, investigation and writing, and their distribution across contributors and works.
Author identification prioritises X-PEN iD, ORCID and email. Possible name-based matches remain subject to review.
When identification or publication-date coverage is incomplete, the repeat-author output share may be presented as a lower bound (≥).
Citation Exclusion Filters
Citation Exclusion Filters allow users to compare metrics calculated from all citations with results excluding platform self-citations, same-author citations, same-organisation citations or same-publisher citations.
- Without platform self-citations: excludes citations between works from the same platform.
- Without same-author citations: excludes citations where the citing and cited works share at least one confirmed author.
- Without same-organisation citations: excludes citations where the citing and cited works share an identified author-affiliated organisation.
- Without same-publisher citations: excludes citations between works from platforms under the same identified publisher.
Each exclusion provides a separate comparison with the all-citations result.

- Submission to acceptance: measure the interval between the recorded submission and acceptance dates.
- Acceptance to publication: measure the interval between acceptance and publication.
- Submission to publication: explore the overall recorded processing timeline.
- Median processing times: compare typical durations and how they change across publication years.
- Date coverage: see how many works have the date pairs required for each calculation.
Reference Profile Metrics
Reference Profile Metrics examine the reference lists registered for scholarly outputs. They describe reference volume, references per output, reference age, identifier coverage, references to works within the same platform, and identified references to retracted works.
- Reference Volume
- Explore total registered references, the average number of references per output, and references-per-output trends by publication year.
- Reference Age
- Explore the median age of references relative to the citing output’s publication year, together with the number of references whose recorded years support the calculation.

- Explore the percentages of references with and without SEIPIDs or DOIs. SEIPID and DOI coverage are measured separately; a reference may contain both identifiers.
- Registry Connections & Own-Platform References
- Explore available connections to registered scholarly records and the share of references pointing to works within the same platform/NiD.
- Retracted References
- Identify registered references connected to works with a recorded retraction status through available Registry matches or recognised identifiers.
- Reference Style Indication
- Explore the indicated reference style, such as APA, Harvard, Vancouver or another supported style. An inferred indication reflects available formatting patterns and may be mixed or undetermined.
- Data Coverage
- Interpret reference measures alongside the available registered reference lists, identifiers and publication years. References supplied by a work are analysed separately from citations that work receives.
Metadata & Citation Format Usage Metrics
Metadata & Citation Format Usage Metrics measure recorded access to scholarly metadata and citation exports in formats such as RIS, BibTeX, CSL-JSON and JSON-LD. They show which formats are requested, by human readers or identified automated systems, and how that activity changes over time.
