ducksemantics vs pedprobr
A side-by-side editorial comparison of ducksemantics and pedprobr — release velocity, themes, recent moves, and the top alternatives to consider.
ducksemantics vs pedprobr: at a glance
What is ducksemantics?
ducksemantics puts an ontology graph and ColBERT retrieval inside DuckDB, callable from R.
ducksemantics is a first release, and an unusually complete one. It combines a DuckDB-native semantic graph, lexical grounding, dense retrieval, exact late-interaction scoring, and structured judgment behind a single R API. The release notes report a full HPO ontology load of 19,836 nodes with 202,740 materialized is_a closure rows, plus persisted EmbeddingGemma and LFM2.5-ColBERT vectors, with DuckDB MaxSim agreeing with an external implementation to seven decimal places.
What is pedprobr?
pedprobr is the likelihood engine, and it keeps finding ways to compute what it previously could not.
pedprobr computes pedigree likelihoods for the ped suite. Version 1.1.0 updated its loop handling to match pedtools 2.11.0, including founder and repeated loop breakers, and improved the peeling algorithm with single-child shortcuts and lower memory use. Version 1.0.0 was the other expansion: special lumping lets markers with mutation models that are un-lumpable in the Kemeny-Snell sense be lumped anyway in certain cases, with alleleLimit as a fallback for the rest.

◆ Current state
ducksemantics is a first release, and an unusually complete one. It combines a DuckDB-native semantic graph, lexical grounding, dense retrieval, exact late-interaction scoring, and structured judgment behind a single R API. The release notes report a full HPO ontology load of 19,836 nodes with 202,740 materialized is_a closure rows, plus persisted EmbeddingGemma and LFM2.5-ColBERT vectors, with DuckDB MaxSim agreeing with an external implementation to seven decimal places.
◆ Where it's heading
With one release on the record there is no trend to read, only a stated posture: correctness first. The release documents transactional and idempotent graph writes, atomic and resumable embedding caches, index preservation across graph projection, and a verified numerical match against a reference MaxSim implementation. That is the profile of a package expecting to be used as infrastructure rather than a demo.
◆ Prediction
Where this goes next is not yet determinable from a single release. The obvious pressure point is ontology coverage beyond the HPO used for validation, but the entries do not indicate a plan.
pedprobr
0.0ANALYTICS
pedprobr is the likelihood engine, and it keeps finding ways to compute what it previously could not.
◆ Current state
pedprobr computes pedigree likelihoods for the ped suite. Version 1.1.0 updated its loop handling to match pedtools 2.11.0, including founder and repeated loop breakers, and improved the peeling algorithm with single-child shortcuts and lower memory use. Version 1.0.0 was the other expansion: special lumping lets markers with mutation models that are un-lumpable in the Kemeny-Snell sense be lumped anyway in certain cases, with alleleLimit as a fallback for the rest.
◆ Where it's heading
Every significant release here removes a class of computation that used to be infeasible, either by making a marker lumpable or by making a loop breakable. The rest is steady peeling-algorithm optimization, which has been reducing memory footprint release after release since 0.9.2. The newly added .diagnostics option suggests the peeling internals are now complex enough that the maintainer needs to inspect them.
◆ Prediction
Since special lumping is documented as covering only some cases so far, expect further lumping situations to be implemented as pedmut adds them.
