|
||
<p>对输入字符串进行一系列自定义的文本标准化处理。</p>
|
||
<p>该算子按顺序执行以下操作：
|
||
1. 将所有大写字母转换为小写字母。
|
||
2. 去除字符串首尾的空白字符 (space, <code class="docutils literal notranslate"><span class="pre">\t</span></code>, <code class="docutils literal notranslate"><span class="pre">\n</span></code>, <code class="docutils literal notranslate"><span class="pre">\v</span></code>, <code class="docutils literal notranslate"><span class="pre">\f</span></code>, <code class="docutils literal notranslate"><span class="pre">\r</span></code>)。
|
||
3. 删除字符串中预定义的一组标点符号 (例如 <code class="docutils literal notranslate"><span class="pre">.*()\"</span></code>)。
|
||
4. 标准化缩写词，例如，将 <code class="docutils literal notranslate"><span class="pre">we</span> <span class="pre">'re</span></code> 转换为 <code class="docutils literal notranslate"><span class="pre">we're</span></code>。
|
||
5. 展开常见的英文缩写词 (例如, <code class="docutils literal notranslate"><span class="pre">n't</span></code> -> `` not``, <code class="docutils literal notranslate"><span class="pre">'ll</span></code> -> `` will``, <code class="docutils literal notranslate"><span class="pre">i'm</span></code> -> <code class="docutils literal notranslate"><span class="pre">i</span> <span class="pre">am</span></code> 等)。
|
||
6. 标准化问号和感叹号，例如合并连续的符号 (<code class="docutils literal notranslate"><span class="pre">!!!</span></code> -> <code class="docutils literal notranslate"><span class="pre">!</span></code>) 并在符号和单词之间添加空格 (<code class="docutils literal notranslate"><span class="pre">Hello?</span></code> -> <code class="docutils literal notranslate"><span class="pre">Hello</span> <span class="pre">?</span></code>)。
|
||
7. 去除字符串首尾预定义的另一组字符 (例如 <code class="docutils literal notranslate"><span class="pre">[\\s,:;\\-&'\"]+</span></code>)。
|
||
8. 再次去除字符串首尾的空白字符。
|
||
9. 如果处理后的字符串长度超过300个字符，则将其截断为300个字符。
|
||
10. 在字符串首部添加前缀 <code class="docutils literal notranslate"><span class="pre"><S></span> <span class="pre">``，尾部添加后缀</span> <span class="pre">``</span> <span class="pre"><E></span></code>。</p>
