			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>Chương trình screen đúng là một trình quản lý terminal rất thông minh và tiện lợi trên unix. Very nice idea.</p>
<p>+ Cho phép mình mở nhiều terminal ảo trên cùng một cửa sổ terminal vật lý<br />
+ Chuyển đổi giữa các terminal dễ dàng<br />
+ Trong trường hợp kết nối tới server (bằng ssh client), khi đường truyền bị ngắt, mình không phải chạy lại từ đầu, có thể khôi phục dễ dàng bằng các tùy chọn lệnh của screen (quá tuyệt)</p>
<p>Nói chung ai nghĩ ra ý tưởng này quả là giỏi.</p>

			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>Minipar là một tool dependency parsing cho tiếng Anh, viết bởi Dekang Lin (<a href="http://www.cs.ualberta.ca/~lindek/minipar.htm" target="_self">http://www.cs.ualberta.ca/~lindek/minipar.htm</a>). Chạy tương đối nhanh, ví dụ trên máy Pentium II 300 với 128MB memory, nó phân tích khoảng 300 từ trên giây, khá nhanh so với một bộ phân tích Denpendency Parsing khác là Stanford Parser (<a href="http://nlp.stanford.edu/software/lex-parser.shtml" target="_self">http://nlp.stanford.edu/software/lex-parser.shtml</a>)</p>
<p>Bài viết nhắm hướng dẫn cách sử dụng tool minipar cho dependency parsing, step by step. Môi trường sử dụng là Unix hoặc Unix-like ví dụ như Cygwin</p>
<p>Step 0: Download minipar từ trang chủ <a href="http://www.cs.ualberta.ca/~lindek/minipar/" target="_self">http://www.cs.ualberta.ca/~lindek/minipar/</a>. Có nhiều version khác nhau, ở đây tôi sử dụng version cho linux 32bit. Giả sử tôi chép vào thư mục ~/nlp/local-tools</p>
<p>Step 1: Giải nénfile minipar-0.5-Linux32.tgz dùng lệnh tar<br />
tar xvfz minipar-0.5-Linux32.tgz</p>
<p>sau đó đổi tên thư mục vừa giải nén ra thánh minipar, xóa file tgz<br />
mv minipar-0.5-Linux32 minipar<br />
rm minipar-0.5-Linux32.tgz</p>
<p>Step 2: Thiết lập đường dẫn cho minipar. Với bash shell, thêm dòng sau vào file .bashrc<br />
export MINIPATH=/cygdrive/d/workspaces/minipar</p>
<p>Step 3: Sử dụng pdemo để phân tích Dependency</p>

			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>Bài viết này trình bày cách cài đặt English Wordnet 3.0 (Từ điển từ vựng điện tử) trên Unix hoặc Cygwin từ mã nguồn</p>
<p>Step 0: Download mã nguồn của Wordnet 3.0 tại địa chỉ <a href="http://wordnetcode.princeton.edu/3.0/WordNet-3.0.tar.gz" target="_blank">http://wordnetcode.princeton.edu/3.0/WordNet-3.0.tar.gz</a> vào một thư mục nào đó chẳng hạn /home/user-name/nlp/src</p>
<p>Step 1: Chuyển vào thư mục chứa file mã nguồn (lệnh cd), giải nén file vừa Download<br />
$tar xvfz WordNet-3.0.tar.gz</p>
<p>Step 2: Chuyển vào thư mục vừa giải nén, trong TH này là: ~/nlp/src/WordNet-3.0</p>
<p>Step 3: Cấu hình file make, dùng lệnh<br />
$./configure  &#8211;prefix=~/nlp/local-tools/wn-3.0</p>
<p>Lệnh này sẽ chỉ ra đường dẫn để cài đặt Wordnet 3.0. Ở đây tôi muốn đặt đường dẫn tại ~/nlp/local-tools/wn-3.0</p>
<p>Step 4: Sau khi thực thi lệnh configure thành công, gõ lệnh make để biên dịch mã nguồn<br />
make</p>
<p>Step 5: Install<br />
$make install</p>
<p>Sau khi cài đặt thành công, ta phải cấu hình đường dẫn mới có thể sử dụng WordNet</p>
<p>Step 6: Tạo biến môi trường WNHOME là đường dẫn tới thư mục mà ta cài đặt WordNet, ở đây là /home/user-name/nlp/local-tools/wn-3.0<br />
Nếu shell đang sử dụng là bash, thêm vào dòng<br />
export WNHOME=/home/user-name/nlp/local-tools/wn-3.0</p>
<p>Thêm đường dẫn thư mục bin (file binary) của wordnet 3.0 vào đường dẫn PATH<br />
export PATH=/home/minhpqn/nlp/local-tools/wn-3.0/bin:$PATH</p>
<p>Bây giờ có thể sử dụng wordnet rồi đó. Cheer!</p>
