不支持的文本语言：自然语言理解 API

Question

我正在使用 IBM 云的自然语言理解 API，但是英语以外的语言给我一个不受支持的语言的错误。

我的请求参数如下所示：

        $url = "https://api.us-south.natural-language-understanding.watson.cloud.ibm.com/instances/****/v1/analyze?version=2017-02-27";
        $token = "apikey:****************";
        $token = base64_encode($token);
        $language = 'de';
        $bodyArray = [
            "text" => $text,
            "features" => [
                "syntax" => [
                    "sentences" => true
                ]
            ],
            "language" => $language
        ];

        $body = json_encode($bodyArray);
        $headers = [
            'Authorization' => 'Basic ' . $token,
            "Content-Type" => "application/json"
        ];

        $client = new Client();
        $request = new GuzzleHttpRequest('POST', $url, $headers, $body);
        $response = $client->send($request);
        $response = $response->getBody()->getContents();

Answer 1

syntax / sentences seems to be an experimental feature and hence only supported for the English language. That feature is not listed in the language support for the GA features 的 NLU 功能。

因此，我认为它不是设计使然。
