Japanese-Slovenian Learner's Dictionary jaSlo

The jaSlo dictionary contains almost 10.000 entries, many of them linked to corpus examples. More infomation about the dictionary can be found it in its TEI header.

The complete dictionary can be downloaded in source TEI P5 format from the CLARIN.SI repository via the permanent URL hdl.handle.net/11356/1050.

Slovenian-Japanese Learner's Dictionary sloJa

The Slovenian-Japanese online dictionary for Slovenian speaking learners of Japanese was compiled by extracting and converting data from jaSlo, first automatically and then manually cleaning double or inappropriate entries, labelling the Slovenian headwords with part-of-speech and difficulty tags according to the CEFR scale as available in the Core Vocabulary of Slovenian (http://hdl.handle.net/11356/1697), and manually edited all entries using Lexonomy.

Senses of polysemous words and corresponding translation equivalents were manually glossed with hints on their meaning, in part also with examples, extracted from the jaSlo parallel corpus, and manually adapted for the learner's dictionary. Japanese translational equivalents from different registers were tagged according to their level of politeness and with notes on usage restrictions aimed at dictionary users who are learning Japanese as a foreign language.

The dictionary can be browsed at https://www.lexonomy.eu/#/sloJa, or downloaded from the CLARIN.SI repository with a CC-BY 4.0 licence, at http://hdl.handle.net/11356/1898.

Japanese Corpora

The jaSlo parallel corpus

The Japanese-Slovenian parallel corpus jaSlo is sentence aligned and contains about half a million words per language from 130 sources.

It is available via the CLARIN.SI noSketch Engine:

• Japanese part
• Slovenian part

The jpWaC-L web corpus

The Japanese web corpus with difficulty levels jpWaC-L contains over 300 million words, with words and sentences annotated with their difficulty level. The corpus is further split into 5 subcorpora, each for one difficulty level, from 4 (easiest) to 0 (hardest).

The difficulty level of the words comes from a lexicon provided by prof. Yoshiko Kawamura, Tokyo International University. Words are assigned difficulty levels according to the Japanese Language Proficiency Test Content Specifications (Revised Edition), Japan Foundation & Association of International Education Japan. Tokyo: Bonjinsha 2004. The difficulty level of the sentences is computed using various heuristics, based on the (difficulty level of) words, sentence length, etc. (c.f. Hmeljak et al. 2010)

The corpus was collected from the Web using WaCkY tools and then processed by Chasen.

The corpus is available as a downloadable dataset from the CLARIN.SI repository (http://hdl.handle.net/11356/1047) as well as for exploration via the CLARIN.SI installation of noSketch Engine, also split by difficulty level:

• jpWaC (Japanese Web, complete corpus)
• jpWaC-L0 (Japanese Web, v.difficult sentences)
• jpWaC-L1 (Japanese Web, difficult sentences)
• jpWaC-L2 (Japanese Web, intermediate sentences)
• jpWaC-L3 (Japanese Web, easy sentences)
• jpWaC-L4 (Japanese Web, v.easy sentences)

Corpus annotation

The corpora were part-of-speech tagged and lemmatised with ChaSen. The ChaSen tags (originally written in Japanese) have been also translated to English tags. In the concordancers the ChaSen-jp tags (i.e. those written in Japanese) are stored in the positional attribute "ctag" ChaSen-en in the attribute "tag". The table below gives the mapping (it is also available as a tabular file):
