Languagetool 是基于规则的。显然,“每天吃我米饭,像个男孩一样上学”这句话还没有被任何规则所抓住。
http://wiki.languagetool.org/tips-and-tricks有关于如何将用户定义的规则添加到 Languagetool 的信息。
以下是此类规则的示例:
<rule>
<pattern>
<token>
<exception regexp="yes">(that|ha[ds]|will|must|could|can|should|would|does|did|may|might|t|let)</exception>
<exception inflected="yes" regexp="yes">feel|hear|see|watch|prevent|help|stop|be</exception>
<exception postag="C[CD]|IN|DT|MD|NNP|\." postag_regexp="yes"></exception>
<exception scope="previous" postag="PRP$"/>
</token>
<token postag="NNP" regexp="yes">.{2,}<exception postag="JJ|CC|RP|DT|PRP\$?|NNPS|NNS|IN|RB|WRB|VBN" postag_regexp="yes"></exception></token>
<marker>
<token postag="VB|VBP" postag_regexp="yes" regexp="yes">\p{Lower}+<exception postag="VBN|VBD|JJ|IN|MD" postag_regexp="yes"></exception></token>
</marker>
<token postag="IN|DT" postag_regexp="yes"></token>
</pattern>
<message>The proper name in singular (<match no="2"></match>) must be used with a third-person verb: <suggestion><match no="3" postag="VBZ"></match></suggestion>.</message>
<short>Grammatical problem</short>
<example correction="walks" type="incorrect">Ann <marker>walk</marker> to the building.</example>
<example type="correct">Bill <marker>walks</marker> to the building.</example>
<example type="correct">Guinness <marker>walked</marker> to the building.</example>
<example type="correct">Roosevelt and Hoover speak each other's lines.</example>
<example type="correct">Boys are at higher risk for autism than girls.</example>
<example type="correct">In reply, he said he was too old for this.</example>
<example type="correct">I can see Bill looking through the window.</example>
<example type="correct">Richard J. Hughes made his Morris County debut in his bid for the Democratic gubernatorial elections.</example>
<example type="correct">... last night got its seven-concert Beethoven cycle at Carnegie Hall off to a good start.</example>
<example type="correct">... and through knowing Him better to become happier and more effective people.</example>

<!-- The present Federal program of vocational education began in 1917. -->
</rule>
有一个在线规则编辑器可在

该问题的一个简单解决方案是
<!-- English rule, 2014-09-19 -->
<rule id="ID" name="EatI">
<pattern> <token>Eat</token> <token>i</token> </pattern>
<message>Instead of <match no="2"/> <match no="1"/> it should be <match no="1"/> <match no="2"/></message>

<short>wrong order of verb and nown</short>
<example type='incorrect'><marker>Eat i</marker> rice</example> <example type='correct'>I eat rice</example>
</rule>
但当然这只会涵盖动词“吃”——但我希望你能明白它是如何工作的……
