Has anyone heard about a replacement for the Conce

问题:

I have been learning about the IBM Watson services and Bluemix over the last few months. I had previously looked at the Concept Expansion service but when I returned to the page where this service is described, I found the message from IBM that this service was being withdrawn: Has anyone seen or heard of an alternative or replacement being suggested or offered by IBM?

The closest equivalent is Concept Insights. It works by making graphs of concepts in a corpus, with each concept having a path within that graph. Many of the Concept Insights APIs are for searching text documents, but you can use the related_concepts endpoint to expand a concept. For example, the following queries concepts related to IBM Watson and Business:

curl -u "{username}":"{ci-password}" -G -d "concepts=[\"/graphs/wikipedia/en-latest/concepts/IBM_Watson\",\"/graphs/wikipedia/en-latest/concepts/Business\"]&level=1&limit=2" "https://gateway.watsonplatform.net/concept-insights/api/v2/graphs/wikipedia/en-latest/related_concepts"

returns this:

{
  "concepts": [
    {
      "score":0.7795701,
      "concept": {
        "id":"/graphs/wikipedia/en-20120601/concepts/Business_intelligence",
        "label":"Business intelligence"
      }
    },
    {
      "score":0.7564283,
      "concept": {
        "id":"/graphs/wikipedia/en-20120601/concepts/Data_model",
        "label":"Data model"
      }
    }
  ]
}

which distills down to "Business Intelligence" and "Data model".

Concept Insights is retired. I am now using AlchemyLanguage and this is working adequately for my needs.
