Provides the classes to take Tibetan language passages and divide the passages up
|
|
|
|
|
into their component phrases and words, and display corresponding dictionary definitions.
|
|
|
|
|
<p>This tool helps Tibetan to English translators partially automate the
|
|
|
|
|
translation process. In the Tibetan language, the boundaries of individual words
|
|
|
|
|
are not marked in any manner such as the way in which spaces separate and mark
|
|
|
|
|
words in English. Instead, there is
|
|
|
|
|
a punctuation mark called a "tsheg" which separates each syllable. Thus while syllabic boundaries are utterly explicit, word boundaries are
|
|
|
|
|
often unclear. One of the main
|
|
|
|
|
difficulties beginning students thus have with translating Tibetan texts is
|
|
|
|
|
figuring out where each word ends and the next word starts, and determining what
|
|
|
|
|
series of syllables to look up in the dictionary either as constituting a single
|
|
|
|
|
word or a larger compound phrase. This
|
|
|
|
|
entails a very time consuming process of looking up multiple combinations of
|
|
|
|
|
syllables to determine which are found within a given dictionary.</p>
|
|
|
|
|
<p>It partially automates that process by
|
|
|
|
|
breaking up a sentence/paragraph entered in <a href="http://iris.lib.virginia.edu/tibet/tools/ewts.pdf" target="_blank">
|
|
|
|
|
Extended Wylie</a> or Tibetan script
|
|
|
|
|
into the biggest component parts it can find in multiple dictionary databases.
|
|
|
|
|
Then for each component part found, it displays its stored definitions and
|
|
|
|
|
relevant information. This will
|
|
|
|
|
thus often yield only the definition of a long phrase, rather than its component
|
|
|
|
|
words, but one can also search for the syllables of that phrase one by one
|
|
|
|
|
separately.</p>
|
|
|
|
|
<p>The tool can run on-line through a:</p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li>
|
|
|
|
|
Java servlet (using Roman script for input and Tibetan script for output)
|
|
|
|
|
directly on a browser<p>The text is typed (or pasted) using <a href="http://iris.lib.virginia.edu/tibet/tools/ewts.pdf" target="_blank">
|
|
|
|
|
Extended Wylie</a> in a
|
|
|
|
|
text box within a form. All of the processing is done on the server, and the
|
|
|
|
|
results are returned in plain HTML. This allows the user to run this version on
|
|
|
|
|
even the most basic browser without needing any additional software installed.
|
|
|
|
|
Also, because the results are returned in HTML, features of HTML like
|
|
|
|
|
hyperlinks, tables, and text formatting allow it to be skimmed more easily. The
|
|
|
|
|
user can choose between seeing the Tibetan within the results in <a href="http://iris.lib.virginia.edu/tibet/tools/ewts.pdf" target="_blank">
|
|
|
|
|
Extended Wylie</a> or in Tibetan script

Java applet & application (using Tibetan script for both input and output)

communicating to a servlet<p>The text is typed in <a href="http://iris.lib.virginia.edu/tibet/tools/ewts.pdf" target="_blank">
|
|

|
|
Extended Wylie</a>, but with the added
|
|
|
|
|
value that optionally the user can choose to see it directly in the Tibetan script
|
|
|
|
|
(<a href="http://iris.lib.virginia.edu/tibet/tools/tmw.html" target="_blank">using
|
|
|
|
|
Tibetan Machine Web font now available for free</a>) as he types. We
|
|
|
|
|
eventually plan to support other keyboard methods of entry as well. Here all the processing is also done on the server side, and the results
|
|
|
|
|
are displayed interactively within the program's window. Again the user can choose
|
|
|
|
|
to see the results in <a href="http://iris.lib.virginia.edu/tibet/tools/ewts.pdf" target="_blank">
|
|
|
|
|
Extended Wylie</a> or in the Tibetan script. </p>
|
|
|
|
|
<p>Even though the application runs as a stand-alone application in the
|
|
|
|
|
desktop's user, connection to the Internet is still necessary to access the
|
|
|
|
|
dictionary databases. Easy launching of the application can be done over the
|
|
|
|
|
Internet using <a href="http://java.sun.com/products/javawebstart/">Java Web
|
|
|
|
|
Start</a>, which comes with <a href="#Sun's Java Runtime Environment">
|
|
|
|
|
Sun's Java Runtime Environment version 1.4</a> or higher. This is the
|
|
|
|
|
recommended way to run the tool.</p>
|
|
|
|
|
<p>The applet runs within a browser. The browser not only needs
|
|
|
|
|
to support Java, but since the classes that handle the Tibetan font use <i>Swing</i>, <a href="#Sun's Java Runtime Environment">
|
|
|
|
|
Sun's Java Runtime Environment version 1.4</a> or higher must additionally be installed.<br>
|
|
|
|
|
</p>
|
|
|
|
|
</li>
|
|
|
|
|
</ul>
|
|
|
|
|
<p>The tool can also run off-line in:</p>

|
|
|
<ul>
|
|
|
|
|
<li><b>Desktop & laptop computers</b>
|
|

|
|
|
|
|
although <a href="#Sun's Java Runtime Environment">version 1.4</a> or higher is
|
|
|
|
|
recommended. This is distributed as <i>DictionarySearchStandalone.jar</i>.</li>

|

<p><i>Notes on Input:</i></p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li>For the "punctuation marks", the tool assumes that
|
|
|
|
|
<ul>
|
|
|
|
|
<li>' ' (tsheg), '_' (space), <enter>, <tab>:
|
|
|
|
|
function as syllable separators and may show up in between component word or phrases.</li>
|
|
|
|
|
<li> '/' (shad), ';', '|', '!', ':', '[', ']', '^', '@', '#', '$', '%', '=', '<', '>',
|
|
|
|
|
'(', ')', '{', '}', <i>blank line</i> (two enters in a row): may not show up in between
|
|
|
|
|
component word or phrases (and hence is interpreted as marking the end of a
|
|
|
|
|
component word or phrase). See <a href="http://iris.lib.virginia.edu/tibet/tools/ewts.pdf" target="_blank">
|
|
|
|
|
Extended Wylie</a> documentation for the corresponding symbols in the
|
|
|
|
|
Tibetan script.
|
|
|
|
|
</li>
|
|
|
|
|
<li>all other characters are part of the syllable<br>
|
|
|
|
|
</li>
|
|
|
|
|
</ul></li>
|
|
|
|
|
<li>To force the parser to "break up" a component word or phrase into
|
|
|
|
|
its individual syllables, use any character of the second set in between the syllables. For
|
|
|
|
|
example, if the entry is:
|
|
|
|
|
<p><i>chos nyid</i></p>
|
|
|
|
|
<p>or</p>
|
|
|
|
|
<p><i>chos<br>
|
|
|
|
|
nyid</i></p>
|
|
|
|
|
<p>the parser will recognize it as a single word "<i>chos nyid</i>".
|
|
|
|
|
But if the entry is:</p>
|
|
|
|
|
<p><i>chos / nyid</i></p>
|
|
|
|
|
<p>or</p>
|
|
|
|
|
<p><i>chos</i></p>
|
|
|
|
|
<p><i>nyid</i></p>
|
|
|
|
|
<p>the parser will assume "chos" and "nyid" are independent,
|
|
|
|
|
and will be looked up separately.</p>
|
|
|
|
|

|
|
