Technology · Polly Knowledge Graph

A knowledge graph is only as good as its evidence.

Each custom, program specific Polly KG, that Elucidata builds, captures directional relationships, not just co-occurance, labelling which way each connection points before it counts as evidence.

What Polly Knowledge Graph Actually Is

Every connection in Polly KG is a specific, labeled claim, not a guess based on what showed up in the same paper.

01

It draws a labeled line, not a blank one
It draws a labeled line, not a blank one
Polly KG draws a specific, labeled line between a gene and a disease, or a drug and a pathway, such as "drives," "inhibits," or "is a marker of," instead of just placing them side by side.

02

One generic label can't answer three questions
One generic label can't answer three questions
Most knowledge graphs connect entities with just associations. Polly KG spells out which relationship is actually present between the entities.

03

More papers isn't more proof
More papers isn't more proof
Polly KG only counts a relationship once it holds up independently in both internal manual review and in outside literature.

Cross-species KG · Comparative genomics biotech

3x

Faster hypothesis generation

A Base-KG foundation from 10+ curated public sources was ready on day one. The team skipped infrastructure work and went straight to scoring, reaching 5 high-confidence targets in 6 months on a graph of 31M+ nodes and 60M+ relationships.
AML target-indication assessment · Differentiation-therapy biotech

4x

Faster target-indication assessment

A biotech developing differentiation therapy that converts leukemia cells to healthy ones used Polly KG to evaluate 10 candidate targets for acute myeloid leukemia in 6 months, versus the typical 15–24 months. The assessment improved the odds of a shortlisted candidate reaching clinical trials from the industry baseline of 1 in 2,000 to 1 in 5.

What This Enables in Target ID

Once the graph is built on direction-graded evidence, your target selection runs on the same standard.

Every relationship graded before it's an edge

Each relationship carries a type, a direction, and a polarity score before it becomes an edge. Contradicting evidence surfaces during scoring, before it costs a validation cycle.

20,000 genes to an investment-ready shortlist

Custom scoring across disease relevance, evolutionary conservation, and druggability narrows a full gene set to a ranked, defensible list.

One graph the rest of your program builds on

Scout-sourced evidence and Xtract-structured proprietary data enter the same graph, so spatial, GWAS, and patient-stratification work start from one consistent schema.

Part of the Elucidata Service Offering

Polly KG is the evidence backbone inside both of Elucidata's partnership models.

Program Partner

Elucidata leads target discovery and uses Polly KG for the customer, scoring each relationship from nomination to validation so contradictions appear before committing to a candidate. Customers get a concise, evidence-backed shortlist.

Infrastructure Partner

When Elucidata owns a customer's computational infrastructure layer, whether that's a knowledge graph deployment, an omics pipeline environment, or an AI co-scientist workflow, Polly KG usually sits underneath it, direction-graded from the day it's built rather than qualified after the fact.

FAQs

Questions From Every Evaluation Call

What is the difference between a co-occurrence knowledge graph and a qualified biomedical knowledge graph?

Co-occurrence counts how often a gene and a disease appear together in the same text, with no direction, no polarity, and no mechanism. Polly KG grades every relationship as supporting, contradicting, or neutral, with a direction and a certainty level, before writing it as an edge. For target identification, that distinction determines which candidates make the shortlist.

What is the difference between target ranking and target validation with Polly KG?

Target ranking narrows a full gene set, commonly around 20,000 candidates, to a scored shortlist using the graph. Target validation uses the same qualified evidence to stress-test specific candidates before a wet-lab commitment. Both run on direction-graded evidence. The question changes from "who should we pursue" to "does this candidate hold up."

How does Polly KG support target identification in drug discovery?

It gives your scoring layer direction-graded evidence for each candidate. Candidates with mixed or contradicting evidence are flagged before they reach the shortlist.

Can the knowledge graph handle rare targets or thin literature?

Yes. Full-text processing recovers evidence from methods sections and supplementary data that abstract-only tools miss, roughly 8 million full-text papers Open Targets' abstract-based evidence layer doesn't reach. Proprietary in-house datasets go through the same qualification pipeline as public literature. That pipeline let one program surface a viable target in a disease area with only a single public dataset available.

How often is the knowledge graph updated?

Literature is ingested continuously. Proprietary data integrates at your program's milestones.

What stage of target discovery does Polly KG support?

The full range, from initial target discovery through target validation. The same graph that ranks a full gene set also carries the contradicting evidence your team needs at the validation stage.

How does AI-driven drug discovery benefit from Polly KG?

AI models that query a co-occurrence graph amplify its noise. Polly KG gives those models qualified, direction-graded inputs, so predictions start from defensible evidence.

A knowledge graph built on co-occurrence isn't defensible.
‍Ours is.
