how to determine language of text
cld-2

in a nutshell: I need to be able to search within Oracle DB inside a certain column, for all occurrences that are not English text, or contain signs like -^ etc'. (capital and non-capital are ok) in general, I'm looking to find all occurrences of other languages, Korean Spanish etc'.

ID    NAME      DATE
1     TEST      2018-12-02 11:09:05
2     TE-ST     2018-12-02 11:09:05
3     测试       2018-12-02 11:09:05

i expect the query to find only row #3.

with test as
(
select 'hello good morning' txt from dual 
union select 'Bad weather' from dual
union select '测试 ' from dual
    union select 'L''Inhêrit ' from dual
    union select 'هلا' from dual
)
select *
from test
where txt != asciistr( txt )

Determine if text is in English?, It would take too much time and too much data. Instead, it is better to find a way to standardize all the words in the observing text. Croatian is a  NVACHAR, NCHAR, NTEXT are the datatypes in SQL Server that can be used for storing non-English characters. Precede the Unicode data values with an N (capital letter) to let the SQL Server know that the following data is from Unicode character set. Without the N prefix, the string is converted to the default code page of the database.

Finding non-English characters is pretty straightforward. @moudiz 's solution will solve that problem. But identifying whether a body of text is written in English or some other language requires some form of AI / ML capability which does not come as standard in Oracle RDBMS.

One possibility might be Oracle Text. The World Lexer has auto-detection support for a number of languages. It may be possible to wrangle its capability to tell whether a piece of text is in English. Find out more. (Caveat: blue sky thinking here, never tried anything like this.)

Another solution would be to build a PL/SQL package which calls Google Translate API. The detect() can identify the language of the passed text. Find out more.

There are a couple of obvious snags:

  1. A lot of organisations would object to passing text from a database to an external site like Google.
  2. If you have a lot of data to test the licensing would get expensive.

Text processing problems with non-English languages, Google's free service instantly translates words, phrases, and web pages between English and over 100 other languages. Hi smirnov, Thanks for the Reply. But, Above Query not giving desired results as expected. It is giving results which contains numerals along with english text.

thanks to @moudiz I was able to find a perfect solution for this. I'm using:

select * from table 
where not  REGEXP_LIKE (field_name, '^[^0-9a-z]+$', 'i');

Google Translate, So what if we only grabbed the English-language data and then worked with that​? automatic language identifiers are very error prone, especially on very short texts. which is very wrong (not even in the same language family as Turkish).

  • I can't think of a pure database solution to this. Example: the word autobus or even bus are valid words in both English and Spanish, and probably a few other languages.
  • In fact, test is a commonly used word in Spanish :)
  • maybe the example of Spanish is indeed wrong, since as you mentioned test is also usable. differentiating between Korean/Chinese or any other type of language where no works are in English is good enough.
  • To be clear, are you looking for text which contains characters which do not appear in English (accents, Cyrillic, etc)? Or do you want to identify words which are not written English?
  • I don't think so. Did you try "lasjdvje" instead of the first string and "aljfei kszzz" for the second one? None of these are *English". True, that's garbage, but - use "dobro jutro" and "gadno vrijeme" which are Croatian translations for your examples; these aren't English for sure either, but your query will return only the last ... huh, no idea what it really is, I don't know that language.
  • @Littlefoot well the above code i used for foreign language. and his requirement was I'm looking to find all occurrences of other languages, Korean Spanish
  • @Littlefoot my select will get the characters are not english, for example `ê' or turkish/arabic/russian/korean characters, and in one of his example he mentioned that. if he wants other then that he can specify so i provide anotehr query
  • The OP said: "search (...) for all occurrences that are not English text". String "dobro jutro" (good morning in Croatian) isn't English, and that SELECT won't return it. As we've already found out, we (Moudiz and me) have different thoughts about it, which is perfectly OK. If the question was "that are not written in English alphabet" (you know, [a-zA-Z]), that would still be very broad as "aaieffnx" is written like that, but certainly isn't a valid English word. Oh well, we'll see what the OP says (if anything). Thank you for the comment, anyway, @APC.
  • @Moudiz perfect, thanks :) it is what i was looking for. i apologize if I wasn't clear enough that i don't really care if the word is valid, i just want to know if in English or not, if some1 misspelled that and wrote thet, i'm ok with that.
  • thank you for your comment, i didnt know about the Google translate API, i will keep it in mind for future notice in case i want to actually validate a word or use some kind of a translation.
  • Note that 1. it is naïve to assume non-7-bit-ascii isn't English (even without considering common characters like £); 2. text can easily contain words from another language without changing the base language. This is a hard problem.
  • Yeah, when seeing people assume English text can only contain ASCII I always get a sense of déjà vu. English dictionaries have a lot of odd stuff in them.
