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 quanteda?

Text analysis in R keeps optimising its token internals — and builds a path out to torch

quanteda is a mature framework for quantitative text analysis in R. Since the 4.0 rewrite around external-pointer tokens objects, releases have concentrated on the internals: recompilation control, memory reduction on concatenation, type-table consistency between tokens and dfm objects. The newest release adds tokens_recompile() for explicit ID reassignment, stops query functions from recompiling implicitly, and returns dense rather than sparse tensors from as.tensor() with arguments passed through to torch.

contentanalysis vs quanteda: editorial side-by-side

C0.0

A scientific-text analysis package moved from counting citations to classifying argument structure.

◆ 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.

Text analysis in R keeps optimising its token internals — and builds a path out to torch

◆ Current state

quanteda is a mature framework for quantitative text analysis in R. Since the 4.0 rewrite around external-pointer tokens objects, releases have concentrated on the internals: recompilation control, memory reduction on concatenation, type-table consistency between tokens and dfm objects. The newest release adds tokens_recompile() for explicit ID reassignment, stops query functions from recompiling implicitly, and returns dense rather than sparse tensors from as.tensor() with arguments passed through to torch.

◆ Where it's heading

Two threads run in parallel. The dominant one is performance and correctness housekeeping on the tokens_xptr representation introduced in 4.0 — each release closes another case where the external-pointer path diverged from the plain tokens path. The quieter thread points outward: as.matrix() returning a document-by-position integer matrix and as.tensor() handing off to torch::torch_tensor() make the tokenised corpus directly consumable by neural models rather than only by quanteda's own bag-of-words machinery.

◆ Prediction

The tensor and matrix export path is the least mature part of the surface and gained arguments in this release rather than settling, so expect further work there before the token internals change again.
