ducksemantics vs spsurvey
A side-by-side editorial comparison of ducksemantics and spsurvey — release velocity, themes, recent moves, and the top alternatives to consider.
ducksemantics vs spsurvey: 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 spsurvey?
spsurvey has spent four years consolidating after its 5.0.0 rewrite rather than adding to it
spsurvey implements design and analysis for spatially balanced environmental survey samples, the GRTS methodology used in large-scale monitoring programs. The 5.0.0 rewrite is the defining event in its history, and everything in this window is aftercare. 5.6.0 in September 2025 finally removed the startup message warning users about that upgrade, several years on.

◆ 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.

spsurvey has spent four years consolidating after its 5.0.0 rewrite rather than adding to it
◆ Current state
spsurvey implements design and analysis for spatially balanced environmental survey samples, the GRTS methodology used in large-scale monitoring programs. The 5.0.0 rewrite is the defining event in its history, and everything in this window is aftercare. 5.6.0 in September 2025 finally removed the startup message warning users about that upgrade, several years on.
◆ Where it's heading
The direction is toward standard R idioms and away from bespoke ones. 5.4.0 introduced sp_frame and sp_design classes so plot() and summary() work directly, keeping sp_plot() and sp_summary() only for backwards compatibility; 5.5.0 moved warnings from cat() to message() so they can be suppressed normally, and added adjwgtNR() for non-response weight adjustment. Documentation is being pushed off CRAN onto the package website, with only the Start Here vignette remaining. Release cadence is slow — five releases across roughly four years.
◆ Prediction
With the migration messaging retired and the class system settled, further releases are likely to stay in maintenance and statistical-detail territory. Nothing in the entries suggests another rewrite.
