A Clojure wrapper library for Sudachi, a Japanese morphological analyzer written in Java.
If you are using Leiningen, clone this repository to your-project/checkouts/ directory. For example, your project files should look like this:
your-project/
project.clj
src/
checkouts/
sudachi-clj/
With Leiningen's checkout dependencies feature, you can define the dependencies in your project.clj as follows:
:dependencies [[org.clojure/clojure "1.10.1"]
[sudachi-clj "0.1.0"]
...]
After that, you can load this library like (require [sudachi-clj.core: as sudachi]).
The morphological analysis engine requires a Sudachi dictionary, which can be downloaded from here.
Once you have downloaded the Sudachi dictionary file, place it in any location (e.g. /path/to/system_core.dic).
By setting the path to the dictionary file in the environment variable SUDACHI_DICTIONARY_FILE, the system can automatically locate the dictionary. Or you can also specify the location as an argument of the start function described below.
Let's play with lein REPL:
lein repl
sudachi-clj.core=>
In order to perform morphological analysis, you must activate the Sudachi system by calling sudachi-clj.core/start function.
sudachi-clj.core=> (start)
:started
Or you can manually specify the location of the Sudachi dictionary, instead of setting the environment variable SUDACHI_DICTIONARY_FILE.
sudachi-clj.core=> (start :dictionary-file "/path/to/system_core.dic")
:started
Now you are ready to analyze sentences. Let's try as follows:
sudachi-clj.core=> (analyze "宇宙、生命、そして万物についての究極の疑問の答え")
[["宇宙" ["名詞" "普通名詞" "一般" "*" "*" "*"]]
["、" ["補助記号" "読点" "*" "*" "*" "*"]]
["生命" ["名詞" "普通名 詞" "一般" "*" "*" "*"]]
["、" ["補助記号" "読点" "*" "*" "*" "*"]]
["そして" ["接続詞" "*" "*" "*" "*" "*"]]
["万物" ["名詞" "普通名詞" "一般" "*" "*" "*"]]
["に" ["助詞" "格助詞" "*" "*" "*" "*"]]
["つい" ["動詞" "一般" "*" "*" "五段-カ行" "連用形-イ音便"]]
["て" ["助詞" "接続助詞" "*" "*" "*" "*"]]
["の" ["助詞" "格助詞" "*" "*" "*" "*"]]
["究極" ["名詞" "普通名詞" "一般" "*" "*" "*"]]
["の" ["助詞" "格助詞" "*" "*" "*" "*"]]
["疑問" ["名詞" "普通名詞" "一般" "*" "*" "*"]]
["の" ["助詞" "格助詞" "*" "*" "*" "*"]]
["答え" ["名詞" "普通名詞" "一般" "*" "*" "*"]]]
Note that the sudachi-clj.core/analyze function returns nil if the system is not started or stopped.
After completing the morphological analysis, it's recommended to shut down the system to free resources, using sudachi-clj.core/stop.
sudachi-clj.core=> (stop)
:stopped
The settings passed to the original Java Sudachi library are defined at :sudachi-clj.config/json in resources/config.edn. If you want to change the plug-in settings and so on, look out there.
