It was designed to consider semantic plausibility in word sequences with recurrent neural network language models, and version 2 rewrote the toolkit around a faster open C++ implementation. ### Project history Kyoto University's Juman++ page links the project as a Japanese morphological analyzer and cites the 2015 EMNLP paper on morphological analysis for unsegmented languages using recurrent neural network language models. The GitHub README describes Juman++ as a new analyzer that uses an RNN language model, and states that version 2 improved accuracy and analysis speed by more than 250 times compared with the original Juman++. The 2018 ACL Anthology system-demonstration paper describes the version 2 toolkit as a C++11/14 lattice-based morphological-analysis library with linear and recurrent neural net language models, plus tools for exposing model problems and partial annotation. ### Adoption history Juman++ gained adoption in Japanese NLP because it improved the accuracy and speed tradeoff of the JUMAN/Jumandic line while keeping a command-line analyzer usable in pipelines. The Homebrew and Nix packages made the analyzer easy to install for developers outside Kyoto University's downloadable tarball workflow. The project also remained academically citeable through EMNLP 2015, ANLP 2018, EMNLP 2018, and a 2020 Journal of Natural Language Processing paper listed by the README. ### How it is used Users run `jumanpp` with UTF-8 Japanese text and receive one analyzed morpheme per line followed by `EOS`. The README documents options such as `--model`, `--beam`, `--specifics`, `--version`, and `--help`. The package distribution includes a pretrained model, while the README warns that building directly from Git does not by itself provide a usable model for analysis. ### Why package nerds care Juman++ is notable to package maintainers because the source tree alone is not the product: usable packages need the analyzer and model assets. That tension is visible in the README's warning that release packages are much larger than source snapshots because they include a pretrained model. It is also a bridge between classic Japanese morphological analyzers and neural NLP tooling: it keeps the Unix filter style while using neural language-model scoring under the hood. ### Timeline - 2015-09: The RNNLM-based Juman++ work appeared at EMNLP 2015. - 2017-12-02: GitHub release v2.0.0-rc1 was published as the first preview. - 2018-03-14: GitHub release v2.0.0-rc2 was published. - 2018-11: The Juman++ toolkit paper appeared in the EMNLP 2018 system demonstrations. - 2023-10-03: GitHub release v2.0.0-rc4 was published. ### Related projects - Juman++ is closely related to JUMAN, Jumandic, KNP, PyKNP, and the Kyoto University Text Corpus ecosystem. - The README points to `jumanpp-jumandic` for training a Jumandic model and to tutorial code for building analyzers for other scriptio continua settings. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** jumanpp - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - jumanpp: normalized package name match | nixpkgs package indexes: pkgs/by-name/ju/jumanpp/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Scientific computing packages](https://www.automicvault.com/pkg/scientific-computing-tools/) - Matched scientific computing metadata. - [juman](https://www.automicvault.com/pkg/brew/juman/) - Shares av.db curated category or tags: cli, japanese, morphological-analysis, natural-language-processing, nlp. - [kytea](https://www.automicvault.com/pkg/brew/kytea/) - Shares av.db curated category or tags: cli, japanese, natural-language-processing, nlp, science. - [freeling](https://www.automicvault.com/pkg/brew/freeling/) - Shares av.db curated category or tags: cli, natural-language-processing, nlp, science. - [sfst](https://www.automicvault.com/pkg/brew/sfst/) - Shares av.db curated category or tags: cli, natural-language-processing, nlp, science. - [link-grammar](https://www.automicvault.com/pkg/brew/link-grammar/) - Shares av.db curated category or tags: cli, natural-language-processing, science. - [openfst](https://www.automicvault.com/pkg/brew/openfst/) - Shares av.db curated category or tags: cli, nlp, science. - [aamath](https://www.automicvault.com/pkg/brew/aamath/) - Shares av.db curated category or tags: cli, science. - [abpoa](https://www.automicvault.com/pkg/brew/abpoa/) - Shares av.db curated category or tags: cli, science. ## Combined YAML source View the package source record on GitHub.
