How SemanticHub works
The product model, core objects, and the complete path of a publication.
SemanticHub is an automated content-intelligence pipeline. It is not merely a news-reading dashboard. Its job is to judge the relevance of incoming articles, combine the related ones into a cluster, and deliver a result where the downstream work happens.
The system relies on a handful of concepts, each defined in exactly one place — the glossary. The rest of this page assumes you know at least five of them: goal, source, article, cluster, and result.

The path of an item
Fetch
The crawler checks a source on its schedule, records new URLs, and extracts their content.
Evaluate relevance
The item is evaluated independently for every goal connected to the source. If no goal accepts it, processing stops.
Embed and group
Accepted material receives one shared embedding and joins a cluster based on semantic similarity and publication time.
Promote
Once the cluster meets the goal’s conditions, it becomes a result. Optional research can enrich a small cluster first.
Process
In direct mode, the cluster is the result. With a workflow enabled, AI steps produce sections defined by the goal’s output contract.
Review and deliver
The result lands in Post moderation, where it waits for approval, or it is sent automatically according to the goal’s delivery policy.
Two ways to finish the pipeline
| Mode | Output | Use it when |
|---|---|---|
| Direct | Cluster description and source articles | The downstream system performs its own processing or you need monitoring without another model call |
| Workflow | Result sections generated by AI steps | The result should be a draft, analysis, or other structured material |
What stays under human control
- the choice of sources and relevance filter;
- grouping thresholds and the moment of execution;
- the models and prompts of workflow steps;
- the final result format — the sections a result is made of;
- the decision to require manual approval or deliver automatically;
- turning off test mode before a real send.
