Mecab output meaning? - Suppaman - 2013-04-03
Hi all
I'm another japanese student. ^_^ Recently I found this tool called mecab able to analyze the japanese text and return info regarding the various chunks. My problem is that I don't understand the info returned. To be more precise I found the meaning of various fields in case of "chasen" output type but this library have also a "detailed" explanation that seem to have a "fixed format" of data show. just for make an example using the test tool provided it show an example like this:
すもももももももものうち
すもも 名詞,一般,*,*,*,*,すもも,スモモ,スモモ
も 助詞,係助詞,*,*,*,*,も,モ,モ
もも 名詞,一般,*,*,*,*,もも,モモ,モモ
も 助詞,係助詞,*,*,*,*,も,モ,モ
もも 名詞,一般,*,*,*,*,もも,モモ,モモ
の 助詞,連体化,*,*,*,*,の,ノ,ノ
うち 名詞,非自立,副詞可能,*,*,*,うち,ウチ,ウチ
EOS
Get the first line:
すもも 名詞,一般,*,*,*,*,すもも,スモモ,スモモ
The first chunk (すもも) is the original "word" to which the information relates. But al the other fields separated by comma what are? Also read the ipadic pdf documentation (the dictionary used by the tool) I can not know which info I should to expect in these field. Especially because in many of these appear very often the symbol '*'.
Someone have a better knowledge that can share with me? ;-)
Thank you

Hi
Thank you very much. The funny thing is that the reply of my question was exactly two lines before the same example block I got as example for this post... Unfortunately the mecab documentation are written all japanese and I was not able to find the info I needed. Thank you again for your help. ^_^

Hi
Thank you for your additional explanation, very useful. Regarding the info returned by mecab I have question about dictionary used. The installable version of mecab is provided with ipadic dictionary. However the author of the library recently made available for download also an additional dictionary called jumandic (download from http://code.google.com/p/mecab/downloads/list). Do you know the difference between these two dictionary and, more important, if both the dictionaries return the same info or change some item description?
Thank you

Hi
Someone can explain me better the difference between 読み and 発音? My translation is "reading" and "pronunciation" but what si the difference between these two terms? In my understanding it sould be the same thing...
Sorry for my ignorance... :-(
Thank you

In my understanding it sould be the same thing...When and how this differs is probably largely dependent on the dictionary used, but consider this example[1]:
雰囲気
読み：ふんいき
発音：ふいんき
The article linked above also lists a couple of other examples.
(Note: This distinction is not present in IPADIC which suggests that in practice they are always exactly the same.)
