将单词添加到语言工具建议列表

Question

我在我的应用程序中使用 LanguageTool 进行一些拼写检查和拼写更正功能。

LanguageTool documentation 描述了如何从拼写检查中排除单词（通过调用您正在使用的拼写检查规则的 addIgnoreTokens(...) 方法）。

如何将一些词（例如来自特定词典的词）添加到拼写检查中？也就是说，LanguageTool 可以修复拼写错误的单词并从我的特定词典中推荐单词吗？

Answer 1

不幸的是，我认为 API 不支持这一点。如果没有 API，您可以将单词添加到 spelling.txt 以使它们被接受并用作建议。对于 API，您可能需要扩展 MorfologikSpellerRule 并更改 this place of the code。（披露：我是 LanguageTool 的维护者）

Answer 2

我有类似的需求，就是将一些自定义词加载到字典中作为 "suggest words"，而不仅仅是 "ignored words"。最后，我扩展了 MorfologikSpellerRule 来执行此操作：

创建 class MorfologikSpellerRuleEx 从 MorfologikSpellerRule 扩展，覆盖方法 "match()"，并编写我自己的 "initSpeller()" 来创建拼写器。
然后对于语言工具，创建此自定义拼写规则以替换现有规则。

代码：

Language lang = new AmericanEnglish();
JLanguageTool langTool = new JLanguageTool(lang);
langTool.disableRule("MORFOLOGIK_RULE_EN_US");

try {
    MorfologikSpellerRuleEx spellingRule = new MorfologikSpellerRuleEx(JLanguageTool.getMessageBundle(), lang);
    spellingRule.setSpellingFilePath(spellingFilePath);
        //spellingFilePath is the file has my own words + words from /hunspell/spelling_en-US.txt
    langTool.addRule(spellingRule);

} catch (IOException e) {
    e.printStackTrace();
}

我自定义的MorfologikSpellerRuleEx代码：

public class MorfologikSpellerRuleEx extends MorfologikSpellerRule {

private String spellingFilePath = null;
private boolean ignoreTaggedWords = false;

public MorfologikSpellerRuleEx(ResourceBundle messages, Language language) throws IOException {
    super(messages, language);
}

@Override
public String getFileName() {
    return "/en/hunspell/en_US.dict";
}

@Override
public String getId() {
    return "MORFOLOGIK_SPELLING_RULE_EX";
}

@Override
public void setIgnoreTaggedWords() {
    ignoreTaggedWords = true;
}

public String getSpellingFilePath() {
    return spellingFilePath;
}

public void setSpellingFilePath(String spellingFilePath) {
    this.spellingFilePath = spellingFilePath;
}

private void initSpellerEx(String binaryDict) throws IOException {
    String plainTextDict = null;
    if (JLanguageTool.getDataBroker().resourceExists(getSpellingFileName())) {
        plainTextDict = getSpellingFileName();
    }
    if (plainTextDict != null) {

        BufferedReader br = null;
        if (this.spellingFilePath != null) {
            try {
                br = new BufferedReader(new FileReader(this.spellingFilePath));
            }
            catch (Exception e) {
                br = null;
            }
        }

        if (br != null) {
            speller1 = new MorfologikMultiSpeller(binaryDict, br, plainTextDict, 1);
            speller2 = new MorfologikMultiSpeller(binaryDict, br, plainTextDict, 2);
            speller3 = new MorfologikMultiSpeller(binaryDict, br, plainTextDict, 3);

            br.close();
        }
        else {
            speller1 = new MorfologikMultiSpeller(binaryDict, plainTextDict, 1);
            speller2 = new MorfologikMultiSpeller(binaryDict, plainTextDict, 2);
            speller3 = new MorfologikMultiSpeller(binaryDict, plainTextDict, 3);
        }

        setConvertsCase(speller1.convertsCase());
    } else {
        throw new RuntimeException("Could not find ignore spell file in path: " + getSpellingFileName());
    }
}

private boolean canBeIgnored(AnalyzedTokenReadings[] tokens, int idx, AnalyzedTokenReadings token)
        throws IOException {
    return token.isSentenceStart() || token.isImmunized() || token.isIgnoredBySpeller() || isUrl(token.getToken())
            || isEMail(token.getToken()) || (ignoreTaggedWords && token.isTagged()) || ignoreToken(tokens, idx);
}   

@Override
public RuleMatch[] match(AnalyzedSentence sentence) throws IOException {
    List<RuleMatch> ruleMatches = new ArrayList<>();
    AnalyzedTokenReadings[] tokens = getSentenceWithImmunization(sentence).getTokensWithoutWhitespace();
    // lazy init
    if (speller1 == null) {
        String binaryDict = null;

        }
        if (binaryDict != null) {
            initSpellerEx(binaryDict);  //here's the change
        } else {
            // should not happen, as we only configure this rule (or rather its subclasses)
            // when we have the resources:
            return toRuleMatchArray(ruleMatches);
        }
    }
    int idx = -1;
    for (AnalyzedTokenReadings token : tokens) {
        idx++;
        if (canBeIgnored(tokens, idx, token)) {
            continue;
        }
        // if we use token.getToken() we'll get ignored characters inside and speller
        // will choke
        String word = token.getAnalyzedToken(0).getToken();
        if (tokenizingPattern() == null) {
            ruleMatches.addAll(getRuleMatches(word, token.getStartPos(), sentence));
        } else {
            int index = 0;
            Matcher m = tokenizingPattern().matcher(word);
            while (m.find()) {
                String match = word.subSequence(index, m.start()).toString();
                ruleMatches.addAll(getRuleMatches(match, token.getStartPos() + index, sentence));
                index = m.end();
            }
            if (index == 0) { // tokenizing char not found
                ruleMatches.addAll(getRuleMatches(word, token.getStartPos(), sentence));
            } else {
                ruleMatches.addAll(getRuleMatches(word.subSequence(index, word.length()).toString(),
                        token.getStartPos() + index, sentence));
            }
