contentanalysis vs mmconvert
A side-by-side editorial comparison of contentanalysis and mmconvert — release velocity, themes, recent moves, and the top alternatives to consider.
Shared themes:r-package
contentanalysis vs mmconvert: at a glance
What is contentanalysis?
A scientific-text analysis package moved from counting citations to classifying argument structure.
contentanalysis parses scientific papers from PDF and analyses their content — citation clustering, reference extraction and matching, word distribution, TF-IDF summaries by section. The most recent release adds a different kind of analysis: sentence-level classification of rhetorical moves, built on Swales' CARS model and extended to literature review and discussion sections, using rules by default with an optional Google Gemini path. PDF handling has been reworked in parallel for multi-column layouts and running header removal.
What is mmconvert?
A single-purpose mouse map interpolator that solved its problem in 2023 and has coasted since
mmconvert does one thing: interpolate between GRCm39 physical positions and the revised Cox genetic map for mouse MUGA array markers. The substantive work all landed in a burst across 2021-2023 — the initial function, the GRCm39 annotation dataset, cross2_to_grcm39(), the recomputed Cox maps and their smoothed replacement. Everything since is upkeep: a warning-message fix in 0.12, and 0.14 is a test adjustment to silence a CRAN Note with no code change at all.

◆ Current state
contentanalysis parses scientific papers from PDF and analyses their content — citation clustering, reference extraction and matching, word distribution, TF-IDF summaries by section. The most recent release adds a different kind of analysis: sentence-level classification of rhetorical moves, built on Swales' CARS model and extended to literature review and discussion sections, using rules by default with an optional Google Gemini path. PDF handling has been reworked in parallel for multi-column layouts and running header removal.
◆ Where it's heading
The arc runs from surface features toward discourse structure. Early releases were about getting references matched correctly and plots readable; the current one asks what function each sentence performs in the argument, which is a categorically harder question and one the package answers with rules first and a language model second. The optional-LLM design is worth noting for what it avoids — the analysis still runs without an API key, and the package has already had to prune retired Gemini model versions once, which is the maintenance cost of depending on a hosted model. Reference parsing is being made format-aware rather than pattern-guessing, with CrossRef enrichment filling in what the PDF omits.
◆ Prediction
Expect the rhetorical move classification to widen to more section types and the rule-based path to keep being the default, given the package has already been forced to track model deprecations on the optional one.
mmconvert
0.0ANALYTICS
A single-purpose mouse map interpolator that solved its problem in 2023 and has coasted since
◆ Current state
mmconvert does one thing: interpolate between GRCm39 physical positions and the revised Cox genetic map for mouse MUGA array markers. The substantive work all landed in a burst across 2021-2023 — the initial function, the GRCm39 annotation dataset, cross2_to_grcm39(), the recomputed Cox maps and their smoothed replacement. Everything since is upkeep: a warning-message fix in 0.12, and 0.14 is a test adjustment to silence a CRAN Note with no code change at all.
◆ Where it's heading
The package has reached the natural end state of a reference-data converter — the reference data stopped moving, so the package stopped moving. Releases now arrive roughly annually and exist to keep CRAN checks green. The 0.14 release shipped the same day as sibling qtl2convert 0.36, confirming these are batch maintenance passes across the maintainer's packages rather than independent development.
◆ Prediction
Without a new mouse genome build or a revised Cox map, the next release is likely another CRAN-check accommodation rather than new functionality.
