ducksemantics vs pedmut: 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 pedmut?
pedmut turns awkward mutation models into ones the likelihood engine can actually handle.
pedmut builds and transforms the mutation models used in pedigree likelihood calculations. Its recent arc is a toolkit of model transformations: makeReversible() with three methods, makeStationary() replacing the older stabilize(), adjustRate() for tuning overall mutation rate, and lumpMutSpecial() for lumping models that strong lumpability cannot handle. The most recent release is narrow, adding a programmatic output format to getParams().

◆ 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.
pedmut
0.0ANALYTICS
pedmut turns awkward mutation models into ones the likelihood engine can actually handle.
◆ Current state
pedmut builds and transforms the mutation models used in pedigree likelihood calculations. Its recent arc is a toolkit of model transformations: makeReversible() with three methods, makeStationary() replacing the older stabilize(), adjustRate() for tuning overall mutation rate, and lumpMutSpecial() for lumping models that strong lumpability cannot handle. The most recent release is narrow, adding a programmatic output format to getParams().
◆ Where it's heading
The consistent goal is making models satisfy the mathematical properties downstream algorithms require. Reversibility, stationarity, and lumpability each unlock something in pedprobr, and the package keeps adding ways to coerce an arbitrary model into having them. lumpMutSpecial() is explicitly incomplete, described as covering only some cases with more possibly to follow, which sets up the main open thread.
◆ Prediction
Expect additional special lumping cases to be implemented, since the package documents the current coverage as partial and pedprobr's likelihood performance depends directly on it.
