Quality Assurance for HTML Annotations

Review visible-text labels in saved HTML pages with their rendered context intact. Resolve span boundaries, field roles, and same-page relationships before releasing webpage training data.
Rendered product-page text annotations surrounded by catalog and job-page review context.

Quality Controls for HTML Annotation

Keep every quality decision tied to the same stored HTML snapshot and the exact text that was labeled.
Reviewing the correct product occurrence among recommendations

Expert Review

Inspect the selected product occurrence among recommendations, navigation, and other page content. Correct text spans, entity properties, or same-page relationships with the rendered snapshot in view.
Independent annotations of the same product page disagree on whether the Price span includes the currency symbol.

Consensus

Collect independent annotations of the same HTML snapshot. Compare field classes and text boundaries, then review differences such as whether a Price span includes its currency symbol.
A saved product offer shows a sale-price benchmark compared with a submission selecting the list price.

Quality Gate (Honeypot)

Compare supported HTML spans, labels, and properties with a hidden approved answer key for the same item. Apply the configured threshold and keep unavailable comparisons on a separate route.
Annotation, consensus, quality gate, expert review and completion stages with failed or rejected work returned to annotation.

QA Workflows

Route saved HTML pages through annotation, consensus, quality gates, and review. Return incomplete spans or incorrect field roles for correction, then complete the reviewed snapshot.

HTML QA for Product and Recruitment Data

Check the exact text and its role in the page instead of treating nearby or repeated content as interchangeable.
HTML specification relation with field properties

Product Fields and Specification Relationships

Review product identity, price roles, and specification values in their rendered context. Check that same-page relationships connect the intended labeled entities and that semantic properties follow the ontology.

Required and Preferred Job Criteria

Distinguish required skills from preferred experience using the wording and headings in a saved job posting. Review contiguous text spans and their configured properties without inferring requirements that the page does not state.

HTML Annotation QA FAQs

What is HTML annotation quality assurance?

It is the review of visible-text entities, same-page relationships, and semantic properties in a stored HTML snapshot. The rendered page helps reviewers distinguish the intended field from surrounding content. QA overview

How do QA Workflows move HTML labels from annotation to approval?

Configure annotation, Consensus, Quality Gate, and Review stages for each saved HTML item. Pass results can advance; failed checks and rejected reviews can return the item for correction. Keeping the same rendered snapshot throughout the workflow lets reviewers resolve the label without losing its page context. QA workflows

How does Consensus compare HTML annotations?

Consensus compares independent annotations of the same stored snapshot, including supported text-span boundaries, labels, and properties. It can expose differences such as a price span that omits its currency symbol. Agreement measures consistency between annotators; a Quality Gate checks an approved answer key. Reviewers still resolve meaning in context. Consensus guide

How does a Quality Gate (Honeypot) check HTML labels?

A Quality Gate compares an eligible HTML submission with an approved, frozen answer key for that snapshot. The key remains hidden from annotators. Supported span and label differences inform the check. Pass and Fail use configured routes, while unavailable or incompatible comparisons follow Not evaluated rather than counting as acceptance. Quality Gate guide

How can reviewers distinguish the intended value from nearby content?

Inspect the highlighted text together with the rendered heading, table, and surrounding page content. On a product page, a sale price may sit beside a previous price or a recommendation. Apply the ontology’s field definition, then check the selected span and its relationship to the intended product. Review stages

What makes an HTML text selection valid?

Each entity must be one contiguous, non-overlapping selection of visible text. A selection can cross adjacent text nodes, but it should not overlap another entity. Define how punctuation, units, and currency symbols belong in each class, then review boundaries consistently across examples of the same field. Review stages

How are relationships and page properties reviewed?

Check that a relationship connects the intended labeled entities within the same snapshot, such as a product and its price. Review the relationship type and direction alongside semantic entity properties. Page-level properties classify the whole item; they are separate from text spans and raw HTML attributes. Review stages

Does review follow the saved snapshot when a website changes?

Review is anchored to the processed snapshot of an uploaded HTML or HTM file. Reflow, Fit, and other display modes change its presentation while preserving source identity. A revised website is a different source; do not assume its text inherits the reviewed spans from an earlier snapshot. Review stages

What context is preserved when reviewed HTML labels are exported?

Versioned releases support JSONL and Unitlab’s native format, preserving labeled text, supported properties, same-page relationships, and snapshot identity. Text anchors and surrounding context connect the labels to their saved source. Check that the release contains the intended snapshot and reviewed annotations before using it for extraction training.
