What to remember
- Justified seed sites
- An explicit co-citation rule
- Visible corpus, depth and date
- Calculated and estimated outputs kept separate
Define the question and corpus
A useful map starts with a question: which sites structure a topic, which sources are cited together, which actors connect communities, or which areas remain poorly documented?
Choose seed sites and explain their role. Set depth, maximum pages, excluded domains and the observation period. These limits are part of the result.
- Research question
- Seed-site list
- Inclusion and exclusion rules
- Depth and maximum volume
- Collection date
Build a co-citation arena
In Nexus co-link mode, an investigation starts from seed sites, follows outbound links and retains domains cited by several seeds. A node represents a domain actor; an edge A → B means A cites B. Citation frequency shows which domains appear across several neighborhoods.
The analysis mode should accompany the result. Co-link finds domains cited by several seeds; snowball expands the neighborhood step by step; inter-actor observes citations among seed sites; sentiment qualifies citation tone. These outputs answer different questions.
| Mode | Question | Caution |
|---|---|---|
| Co-link | Who is cited by several seed sites? | The retention rule defines the arena |
| Snowball | How far does the neighborhood extend? | Depth materially changes the corpus |
| Inter-actor | How do seed sites cite one another? | No link does not mean no relationship |
| Sentiment | What is the tone of citations? | Qualification depends on collected text |
Read indicators with care
PageRank indicates centrality in the constructed network. Betweenness identifies nodes located on many paths. Community methods such as Louvain reveal structural groups.
Nexus also calculates structural measures such as k-core, participation, harmonic closeness and source concentration. Some measures may be unavailable: a missing result remains “not calculated” and is never artificially converted to zero.
Each metric measures a precise structural dimension. Trust, editorial quality and offline influence require complementary evidence; interpretation depends on the corpus, link type and collection parameters.
- Centrality ≠ quality
- Community ≠ real organization
- No link ≠ no relationship
- Missing result ≠ zero
- Comparison requires consistent granularity
Connect network structure to SEO opportunities
When the crawl produces a usable text corpus, Nexus can group documents by similarity, surface themes and identify coverage gaps. Opportunities are weighted by observed centrality in the arena: they prioritize editorial investigation rather than guarantee rankings.
The “citations in the arena” lens shows which domains are cited by the sites actually crawled. The denominator remains visible: a map with hundreds of domains may rely on far fewer pages that were actually read.
- Themes from the collected corpus
- Coverage gaps weighted by arena centrality
- Crawled sites separated from referenced domains
- Editorial validation before content creation
Separate calculated from estimated outputs
Graph measures, citation counts and deterministic corpus analysis are calculated outputs. SEO narratives, value propositions or model-generated interpretations are estimated outputs and retain the provider name.
This separation matters for GEO: a synthesis is more useful when readers can retrieve the corpus, calculation rules and limits. Estimated status remains explicit in the final wording.
| Output | Status | Expected control |
|---|---|---|
| Links, citations, PageRank, communities | Calculated | Corpus, parameters and date |
| Themes and coverage gaps | Calculated on the corpus | Analyzed documents and thresholds |
| SEO narrative or AI synthesis | Estimated | Named provider and human validation |
| JSON or GEXF export | Traceable | Provenance retained in the deliverable |
What Nexus currently supports
Nexus is an Innovatio module outside the seven-module Innovatio Decision Suite. It structures web investigations, explores actors and co-citations, calculates indicators, compares observations over time and exports JSON or GEXF data.
Its current version is used locally on a bounded corpus. AI-assisted interpretations, third-party collectors and Memgraph are activated according to the investigation need.
The map can guide monitoring, reveal dependence on a few sources, identify bridges or suggest topics to verify. It should lead to validation rather than a definitive ranking of actors.
Frequently asked questions
What is a co-citation in Nexus?
In co-link mode, Nexus observes which domains are cited by several seed sites. The map therefore depends on the selected seeds and collection limits.
What does high centrality mean?
It indicates a structural position in the collected network. Evaluating influence requires complementary evidence.
Where does Nexus sit within Innovatio?
Nexus is an Innovatio module outside Innovatio Decision Suite. Its current version is used locally to explore bounded corpora and actor networks.
How can Nexus support SEO or GEO?
Nexus helps identify themes, coverage gaps and citations in a bounded arena. These observations then inform editorial validation and search-result evaluation.
Which scope does the network reflect?
It reflects the seed sites, rules, limits and dates of collection. These parameters accompany every interpretation.
