node.js - 我无法从 Watson Discovery 收到任何答复

Question

我正在使用 Watson Assistant 和 Discovery 的聊天机器人中工作，但我无法从 Discovery 收到任何答复这是我使用发现意图时的对话框

这是我设计的 UI 的输出

function updateMessage(res, input, response) {
// if (!response.output) {
//     response.output = {};
// } else 
if (response.output.action === 'callDiscovery') {
  // if you want to use natural_language_query, set here the input from the user like my example: 
  params.natural_language_query = response.input.text || null;

    console.log('Calling discovery');
    discovery.query(params, (error, returnDiscovery) => {
        if (error) {
          next(error);
        } else {
          console.log('return from discovery: '+returnDiscovery);
          //if you want to send all text returned from discovery, discomment these lines
            var text;
              for (i = 0; i < returnDiscovery.results.length; i++) {
                text += returnDiscovery.results[i].text + "<br>";
              }
          //sending the TEXT returned from discovery results
          response.output.text = 'Discovery call with success, check the results: <br>' + text; //results */
          //sending the PASSAGES returned from discovery results
          response.output.text = 'Discovery call with success, check the results: <br>' + returnDiscovery.passages[0].passage_text; //passageResults
          return res.json(response);
        };
    });
} else if (response.output && response.output.text) {
    return res.json(response);
}

}

分词器应该是 lemmatizer.lemmatize 而不是 lemmatizer

 lemmatizer = WordNetLemmatizer()
 TFIDF = TfidfVectorizer(tokenizer=lemmatizer.lemmatize,analyzer= 'word',min_df=3,token_pattern=r'(?u)\b[A-Za-z]+\b',stop_words= 'english')

输出

TFIDF.fit_transform(['how are you', 'facing issue','hope this well help you' ])
