3 years ago What you're asking the web site for is a different query than what you're asking the API for.
You can get the results the Web interface uses from: http://api.conceptnet.io/c/en/lead_singer
and to get exactly the same results, including the grouping by relation type: http://api.conceptnet.io/c/en/lead_singer?grouped=true
The /related/ query uses machine learning to suggest related concepts, including those that aren't connected by a single edge. It has a more limited vocabulary -- particularly in the smaller version can be queried quickly enough to run a public API -- and when you ask it for a phrase that's outside of its vocabulary, one of the ways it deals with it is to try to reduce it to a prefix that it knows about. Unfortunately, what it found in its vocabulary here was the prefix /c/en/lead, which of course leads to the results about lead-acid batteries and such.
I don't know specifically if "lead singer" is in the vocabulary of ConceptNet Numberbatch, the larger downloadable version of the machine-learned embeddings, but it's worth a try: https://github.com/commonsense/conceptnet-numberbatch

On browse page ConceptNet.io, search for "lead singer" gives reasonable return of related terms, as below:
Related terms
en front man (n) ➜ en frontman ➜ en frontwoman ➜ en vocalist ➜ en band ➜
However when accessing through python/API in this way:
obj = requests.get('http://api.conceptnet.io/related/c/en/lead_singer?filter=/c/en').json()
seem that it cannot handle the phrase:

Does anybody know what's happening here?
