Tablassert
Extract knowledge assertions from tabular data into NCATS Translator-compliant KGX NDJSON — declaratively, with entity resolution built in and optional quality control.
Tablassert turns biomedical spreadsheets (Excel, CSV, TSV) into knowledge graphs ready for NCATS Translator. Declare how your columns map to subject–predicate–object statements in YAML; Tablassert resolves free text to standard CURIEs, attaches provenance and statistical annotations, and emits KGX-compliant nodes and edges.

Quick Start
pip install tablassert
Given a CSV of gene–disease associations with p-values and sample sizes, declare the mapping in a
table config (table.yaml):
template:
source:
kind: text
local: ./gene-disease.csv
url: https://example.com/data.csv
row_slice: [1, auto]
delimiter: ","
statement:
subject: { method: column, encoding: A, prioritize: [Gene] }
predicate: associated_with
object: { method: column, encoding: B, prioritize: [Disease] }
provenance: { repo: PMID, publication: "12345678" }
annotations:
- { annotation: p_value, method: column, encoding: C }
- { annotation: supporting_study_size, method: column, encoding: D }
Wrap it in a graph config (graph.yaml) pointing at your fullmap entity-resolution database
and carrying the required rig: metadata for the generated Resource Ingest Guide:
name: MY_KG
version: 1.0.0
tables:
- ./table.yaml
fullmap: /path/to/fullmap
rig:
source_info:
infores_id: infores:my-kg
terms_of_use_info:
terms_of_use_url: https://example.org/terms
data_access_locations:
- My source downloads - https://example.org/downloads
source_status: maintained_regular_updates
ingest_info:
utility: Gene-disease associations support Translator disease-mechanism queries.
scope: Gene-disease associations extracted from tabular sources.
provenance_info:
contributions:
- "Author Name - code author, data modeling"
artifact_base_url: https://example.org/my-kg
artifact_base_path: ./published/my-kg
Build the knowledge graph:
tablassert build-kg graph.yaml
Output is one JSON object per line — nodes with Biolink categories, edges with annotations:
{"id":"HGNC:11998","name":"TP53","category":["biolink:Gene"],"taxon":"NCBITaxon:9606"}
{"id":"MONDO:0008903","name":"lung cancer","category":["biolink:Disease"]}
{"subject":"HGNC:11998","predicate":"biolink:associated_with","object":"MONDO:0008903","p_value":"1.0000e-03","supporting_study_size":"450"}
See the Tutorial for the full walkthrough.
Key Features
- Declarative YAML configuration — define data transformations without writing code
- Built-in entity resolution — map free text to genes, diseases, and chemicals with standard CURIEs, taxonomic filtering, and provenance, backed by an embedded redb database
- Optional quality control — a four-stage audit (exact → fuzzy → abbreviation → SapBERT embeddings) flags low-confidence mappings
- KGX compliance — emits NCATS Translator-compatible node/edge NDJSON with Biolink categories and predicates
- Autonomous agent —
tablassert agentderives, builds, and refines configs for whole papers - Performance & reproducibility — lazy Polars pipelines and a deterministic UV-based development environment
Installation
pip install tablassert
Or with uv: uv tool install tablassert. The base install builds knowledge graphs from
CSV/TSV/Excel sources; optional extras add runtime and pipeline capabilities:
| Extra | Adds | Install |
|---|---|---|
rt |
CPU-compatible Polars runtime | pip install "tablassert[rt]" |
aria2 |
bundled aria2c downloader for build-fullmap --aria2c (Linux/Windows wheels only) |
pip install "tablassert[aria2]" |
qc |
four-stage QC audit (exact → fuzzy → abbreviation → SapBERT embeddings) | pip install "tablassert[qc]" |
agent |
autonomous agent (smolagents, litellm, PDF context) | pip install "tablassert[agent]" |
optimize |
GEPA prompt optimization for agent --optimize (dspy) |
pip install "tablassert[optimize]" |
QC is opt-in at build time (build-kg --qc). Reaching a feature whose extra is not installed never
produces a bare ModuleNotFoundError: the failure names the missing package and the exact install
command, and for build-kg --qc and tablassert agent it arrives before the run starts rather than
partway through. See the
Installation guide for the full matrix and the
CLI Reference for every flag.
Entity Resolution API
from pathlib import Path
from tablassert.lib import resolve_many
results = resolve_many(
col="gene",
entities=["TP53", "BRCA1"],
fullmap=Path("/path/to/fullmap"),
taxon="9606",
)
# [{"original_gene": "TP53", "gene": "HGNC:11998", "gene_name": "TP53", ...}, ...]
Point resolve_many() at a fullmap database to resolve any iterable of entity strings to CURIEs —
no LazyFrame setup or NLP preprocessing required. See the
Batch Resolution API for the full reference.
