认知服务主题检测 API 不返回任何结果 [英] Cognitive Services Topic Detection API not returning any results

问题描述

我似乎无法从用于主题检测的认知服务文本分析 API 获得任何结果.我下载了API 定义"，并使用我下载的 Swagger 元数据文件将 REST API 客户端生成到 C# 项目中.

I can't seem to get any results back from the Cognitive Services Text Analytics API for Topic Detection. I downloaded the "API definition" and generated the REST API Client into a C# project using the Swagger metadata file that I downloaded.

我正在运行一个测试，其中包含 2000 多个包含常用短语的小句子，因此检测应该有效.代码构造如下:

I'm running a test that included 2000+ small sentences that include common phrases so the detection should work. The code is constructed as follows:

1. 我创建了一个 TopicDetectionInputV2 对象，向其中添加了 2000 多个 InputV2 文档.尝试使用和不使用 StopWords 和 TopicsToExclude.

1. I created an TopicDetectionInputV2 object to which I added the 2000+ InputV2 documents. Tried with and without the StopWords and TopicsToExclude.

我创建了一个 AzureMachineLearningTextAnalytics 对象，我将其称为 DetectTopics(key, null, null, null, TopicDetectionInputV2).尝试了每个单词集的最小/最大文档.

I created an AzureMachineLearningTextAnalytics object that I call the DetectTopics(key, null, null, null, TopicDetectionInputV2). Tried both min/max documents per word set.

我总是收到来自 API 调用的空响应.

I always receive a null response from the API call.

当我调试生成的 REST API 调用并检查 httpResponse 时，它总是返回 Status Code: 202 和 ReasonPhrase: 'Accepted'code>，但是响应体是空的.

When I debug into the generated REST API call and inspect the httpResponse, it always returns a Status Code: 202 and ReasonPhrase: 'Accepted', however the response body is empty.

有没有人能够从 DetectTopics API 获得实际结果?任何信息都非常感谢.

Has anyone been able to get actual results from the DetectTopics API? Any information is greatly appreciated.

推荐答案

我没有使用过这个 API，但根据文档，这是预期的行为.

I haven't used this API, but according to the documentation this is the expected behavior.

DetectTopics API返回 202(正在处理)或 400(错误).

DetectTopics API will either return a 202 (processing) or 400 (error).

成功提交请求后，您应该使用 OperationStatus API.

Once the request has successfully been submitted, which is appears that it has, you should get the result using the OperationStatus API.
