LotusScript to translate text between languages

I am currently working to update our Sametime Bot with a new feature: translation of text. It will be a prompted flow where user is asked for input language, output language and text. The answer from the bot is the translated text. The translation is done by using a LotusScript agent which gets the translation from Google Translate page. LotusScript agent uses MSXML object for web communication with the Goggle server.
See below for an example of translation between English and German.
Pictures show the messagebox for German, Spanish, French and Russian translations. The translation is of course not perfect, but enough good to understand the general meaning.
The best automated translator I've seen so far is by the company "Prompt": http://www.e-promt.com/ It produces very correct translations and even sees the difference between "hello all Domino developers" and "hello to all Domino developers".


Sub Initialize
Dim xmlhttp, MySoap
Dim StartTag As String,EndTag As String, FromLang As String, ToLang As String, TextToTranslate As String
StartTag= |<div id=result_box dir="ltr">|
EndTag = "</div>"
FromLang="en"
ToLang="de"
TextToTranslate="hello all Domino developers"
TextToTranslate=Replace(TextToTranslate," ","%20")

WebServer="http://translate.google.com/translate_t?text="+TextToTranslate+"&hl=en&langpair="+FromLang+"|"+ToLang+"&ie=utf-8"
Set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP")
Call xmlhttp.open("GET", WebServer, False)
Call xmlhttp.setRequestHeader("Content-Type", "text/html; charset=utf-8")
Call xmlhttp.setRequestHeader("User-Agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)")
Call xmlhttp.setRequestHeader("Accept","image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*")
Call xmlhttp.setRequestHeader("Accept-Language","sv")
Call xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded")
Call xmlhttp.send(Null)

strxml = xmlhttp.responseText

Msgbox Strleft(Strright(strxml,StartTag),EndTag)

End Sub

hej Andrei, some creative work!

Sounds cool... have you seen the RTTS stuff over at the greenhouse site? https://greenhouse.lotus.com/home/html/inside/instructions.jsp

Andrei Kouvchinnikov said...

Yes, I've checked both Greenhouse and BleedYellow. Real-Time Translation Services (RTTS) can be interesting for multi-national companies, but I guess that even then, RTTS will be used only as last resort.

Nate said...

Andrei, you might find it interesting that Google now puts a captcha check in front of their translator software if you use this approach. :-(

I'm working on a conversion of this script to Yahoo's Babelfish

Andrei Kouvchinnikov said...

Nate, I have just tested the code and URL and it worked fine. Maybe Google shows capcha check only for certain countries?

Hi Andrei,

Thanks for the code. FYI, I've modified it so that it can be used in Lotus Notes. Basically it will translate selected text to English. ^_^

Hi Andrei. How can I replace the translate.google.com site with the e-prompt online translator with your code?
