<span class="sd">A WordNet Browser application which launches the default browser</span>
<span class="sd">(if it is not already running) and opens a new tab with a connection</span>
<span class="sd">to http://localhost:port/ . It also starts an HTTP server on the</span>
<span class="sd">specified port and begins serving browser requests. The default</span>
<span class="sd">port is 8000. (For command-line help, run "python wordnet -h")</span>
<span class="sd">This application requires that the user's web browser supports</span>
<span class="sd">Javascript.</span>
<span class="sd">BrowServer is a server for browsing the NLTK Wordnet database It first</span>
<span class="sd">launches a browser client to be used for browsing and then starts</span>
<span class="sd">serving the requests of that and maybe other clients</span>
<span class="sd">Usage::</span>
<span class="sd"> browserver.py -h</span>
<span class="sd"> browserver.py [-s] [-p <port>]</span>
<span class="sd">Options::</span>
<span class="sd"> -h or --help</span>
<span class="sd"> Display this help message.</span>
<span class="sd"> -l <file> or --log-file <file></span>
<span class="sd"> Logs messages to the given file, If this option is not specified</span>
<span class="sd"> messages are silently dropped.</span>
<span class="sd"> -p <port> or --port <port></span>
<span class="sd"> Run the web server on this TCP port, defaults to 8000.</span>
<span class="sd"> -s or --server-mode</span>
<span class="sd"> Do not start a web browser, and do not allow a user to</span>
<span class="sd"> shutdown the server through the web interface.</span>

<span class="s2"><h2>NLTK Wordnet Browser Help</h2></span>
<span class="s2"><p>The NLTK Wordnet Browser is a tool to use in browsing the Wordnet database. It tries to behave like the Wordnet project's web browser but the difference is that the NLTK Wordnet Browser uses a local Wordnet database.</span>
<span class="s2"><p><b>You are using the Javascript client part of the NLTK Wordnet BrowseServer.</b> We assume your browser is in tab sheets enabled mode.</p></span>
<span class="s2"><p>For background information on Wordnet, see the Wordnet project home page: <a href="http://wordnet.princeton.edu/"><b> http://wordnet.princeton.edu/</b></a>. For more information on the NLTK project, see the project home:</span>
<span class="s2"><a href="http://nltk.sourceforge.net/"><b>http://nltk.sourceforge.net/</b></a>. To get an idea of what the Wordnet version used by this browser includes choose <b>Show Database Info</b> from the <b>View</b> submenu.</p></span>
<span class="s2"><h3>Word search</h3></span>
<span class="s2"><p>The word to be searched is typed into the <b>New Word</b> field and the search started with Enter or by clicking the <b>Search</b> button. There is no uppercase/lowercase distinction: the search word is transformed to lowercase before the search.</p></span>
<span class="s2"><p>In addition, the word does not have to be in base form. The browser tries to find the possible base form(s) by making certain morphological substitutions. Typing <b>fLIeS</b> as an obscure example gives one <a href="MfLIeS">this</a>. Click the previous link to see what this kind of search looks like and then come back to this page by using the <b>Alt+LeftArrow</b> key combination.</p></span>
<span class="s2"><p>The result of a search is a display of one or more</span>
<span class="s2"><b>synsets</b> for every part of speech in which a form of the</span>
<span class="s2">search word was found to occur. A synset is a set of words</span>
<span class="s2">having the same sense or meaning. Each word in a synset that is</span>
<span class="s2">underlined is a hyperlink which can be clicked to trigger an</span>
<span class="s2">automatic search for that word.</p></span>
<span class="s2"><p>Every synset has a hyperlink <b>S:</b> at the start of its</span>
<span class="s2">display line. Clicking that symbol shows you the name of every</span>
<span class="s2"><b>relation</b> that this synset is part of. Every relation name is a hyperlink that opens up a display for that relation. Clicking it another time closes the display again. Clicking another relation name on a line that has an opened relation closes the open relation and opens the clicked relation.</p></span>
<span class="s2"><p>It is also possible to give two or more words or collocations to be searched at the same time separating them with a comma like this <a href="Mcheer up,clear up">cheer up,clear up</a>, for example. Click the previous link to see what this kind of search looks like and then come back to this page by using the <b>Alt+LeftArrow</b> key combination. As you could see the search result includes the synsets found in the same order than the forms were given in the search field.</p></span>
<span class="s2"><p></span>
<span class="s2">There are also word level (lexical) relations recorded in the Wordnet database. Opening this kind of relation displays lines with a hyperlink <b>W:</b> at their beginning. Clicking this link shows more info on the word in question.</p></span>
<span class="s2"><h3>The Buttons</h3></span>
<span class="s2"><p>The <b>Search</b> and <b>Help</b> buttons need no more explanation. </p></span>
<span class="s2"><p>The <b>Show Database Info</b> button shows a collection of Wordnet database statistics.</p></span>
<span class="s2"><p>The <b>Shutdown the Server</b> button is shown for the first client of the BrowServer program i.e. for the client that is automatically launched when the BrowServer is started but not for the succeeding clients in order to protect the server from accidental shutdowns.</span>

<span class="s2"><li>All underlined texts are hypertext links. There are two types of links:</span>
