<p>It helps to understand when and how pretranslate will merge. The default is to follow msgmerge’s behaviour but we add some extra features with fuzzy matching:</p> <ul class="simple"> <li>If everything matches we carry that across</li> <li>We can resurrect obsolete messages for reuse</li> <li>If we cannot find a match we will first look through the current and obsolete messages and then through any global translation memory</li> <li>Fuzzy matching makes use of the <a class="reference internal" href="levenshtein_distance.html"><em>Levenshtein distance</em></a> algorithm to detect the best matches</li> </ul> </div> <div class="section" id="performance"> <span id="pretranslate-performance"></span><h2>Performance<a class="headerlink" href="#performance" title="Permalink to this headline">¶</a></h2> <p>Fuzzy matches are usually of good quality. Installation of the <a class="reference external" href="https://sourceforge.net/project/showfiles.php?group_id=91920&package_id=260161">python-Levenshtein</a> package will speed up fuzzy matching. Without this a Python based matcher is used which is considerably slower.</p> <p>Install psyco for additional speedup (it is used by most toolkit tools if it is installed.)</p> </div> </div> </div> <hr> <footer class="footer"> <div class="container"> <p class="pull-right"><a href="#">Back to top ↑</a></p> <ul class="unstyled muted"> <li><small> © 2012, Translate.org.za.<br/> </small></li> <li><small> Created using <a href="http://sphinx.pocoo.org/">Sphinx</a> 1.1.3. </small></li> </ul> </div> </footer> </body> </html>
