What This Enables in Target ID

With Xtract running, your documents, clinical, omics, and regulatory data becomes an AI-ready asset.

Clinical trial intelligence at scale

Endpoints, eligibility criteria, dosing arms, and biomarkers extracted from hundreds of reports, structured for target identification without manual reading.

Knowledge graph-ready structured data

Every extracted value mapped to your schema and normalized to any specific ontology, such as MONDO, UBERON, and MeSH.

Full audit trail per extracted value

Every field hyperlinks to its source sentence, so a reviewer can open the original document text behind any number, making it 4x faster with human level quality.

Part of the Elucidata service offering

Xtract powers the curation layer across four of Elucidata's partnership models.

Program Partner

Xtract structures your proprietary documents, CRO reports, assay data, and trial protocols for ingestion into the program-specific knowledge graph, at 98% field-level accuracy, with full audit trails carried through to the validation stage.

Data Harmonization Partner

Xtract is the extraction layer ahead of harmonization, turning unstructured documents, including patient-level EMR/EHR exports, into schema-enforced records before they enter the harmonization pipeline.

Infrastructure Partner

When Elucidata owns a customer's computational infrastructure layer, Xtract is the extraction step underneath it, turning unstructured proprietary documents into schema-enforced records the rest of that infrastructure runs on.

Bioinformatics Partner

Building a multi-omic and clinical profile of a patient subgroup, one of the translational offerings under this partnership, starts with Xtract pulling structured values out of the unstructured clinical sources behind that population's records, ahead of cohort profiling.

Questions From Every Target ID Evaluation Call

What document types does Xtract handle?

PDFs (native and scanned), Word, spreadsheets, HTML and LaTeX-based tables, CRO reports, EMR/EHR exports, and clinical protocols. No pre-processing required.

Why six specialized agents rather than one general LLM?

A general-purpose LLM loses context in long documents and returns no confidence signal. Xtract runs six agents, parsing, entity extraction, knowledge lookup, ontology mapping, schema generation, and quality control, each built for one step of schema-enforced curation at scale, with a human review loop for anything flagged.

What accuracy benchmarks does Xtract achieve?

What accuracy benchmarks does Xtract achieve? 98% accuracy, matching or exceeding human-expert benchmarks, with 100% consistency across binary fields over repeated runs and 90% groundedness, meaning extracted values trace back to source. Across a 50+ field benchmark spanning study design, trial arms, and outcomes, accuracy runs at 90%+ for binary and textual fields and roughly 87% for numeric fields, with F1 scores above 85% across most field types.

Which Elucidata programs use Polly Xtract?

Both partnership models. In Program Partner engagements, Xtract structures proprietary documents for knowledge graph ingestion, from nomination through validation. In Data & Harmonization Partner engagements, it's the extraction layer that turns unstructured and patient-level documents into schema-enforced records ahead of harmonization.

How does Xtract support target identification in drug discovery?

Xtract turns unstructured documents, CRO reports, protocols, publication supplements, into structured records ready for knowledge graph ingestion, with every value traceable to its source.

Can Xtract process proprietary data?

Yes. Internal assay reports, LIMS exports, and regulatory submissions go through the same pipeline as public sources.
