Description

From the listing uploaded by “appupdater”.

JDict is a Japanese-English offline dictionary featuring over 160000 entries, over 10000 kanji and almost 60000 example sentences. It is largely inspired by well-known "[Imi_wa?]" dictionary for [i_O_S] platform both functionally and visually. Current features: - works offline - shows kana/romaji as you type - supports wildcards in vocabulary - recent words, examples and kanji - romaji mode in search - kanji search is divided by ON/KUN readings, Nanori and meaning results - very fast example search - extract words from sentences feature - kanji stroke order animations - furigana is matched everywhere with my own algorithm (still can have some bugs though) - in component view, you can see all kanji with given component ordered by JLPT level and word commonness - in kanji view, you can see all compounds with given kanji ordered like above - search kanji by components (design inspired by "Japanese" dictionary) - browse kanji by JLPT and School Grades - notes - lists (works like favorites but with folders/sub-folders) - vocabulary search recognizes some basic grammar when typing - in word detail view examples are categorized by word meaning if such a connection exists As you can see features are mostly basic for now. The database file is quite big (~230MB). The reason for that is that it contains a lot of example sentences data and needs a lot of indexes to run smooth. My plans: - make the application more user-friendly (list search) - learn vocabulary feature (using lists) - exporting lists to Anki - external links in vocabulary - kanji handwriting recognition - Shiratori game - improve extract words algorithm (I have some ideas using the statistical approach to make it run faster) Acknowledgments: - Electronic Dictionaries Research Groups - KanjiVG - Tatoeba - KanjiCafe - Tanos (JLPT)
