No entities are Returned using Microsoft Academic API

Question

I used the following API call to get the information from Microsoft Academic API: https://api.labs.cognitive.microsoft.com/academic/v1.0/evaluate?expr=Ti=='bayesian modelling of student misconceptions in the one-digit multiplication with probabilistic programming.' I get the following message: Request-Context: appId=cid-v1:8d5cbad1-6ca8-4d39-8271-8f3a8d671eae Date: Sun, 31 May 2020 10:49:04 GMT X-Powered-By: ASP.NET Content-Length: 157 Content-Type: application/json; charset=utf-8

{ "expr": "Ti=='bayesian modelling of student misconceptions in the one-digit multiplication with probabilistic programming.'", "entities": [], "timed_out": false } No entities are returned.Don't know why.Could someone help me with this?

Answer 1

It works for me if I search like this (without the hyphen between one and digit):

https://api.labs.cognitive.microsoft.com/academic/v1.0/evaluate?&expr=Ti==%27bayesian%20modelling%20of%20student%20misconceptions%20in%20the%20one%20digit%20multiplication%20with%20probabilistic%20programming%27&attributes=AA.AuN,AA.AuId,DOI,Ti,VFN,Y&orderby=Y:desc&subscription-key={YOUR-KEY}

If you are unsure about the exact title, but know the first words, then you could add three dots ... after the shortened Ti-value (and before the next field), as in: expr=Ti='bayesian modelling of student misconceptions'...&attributes={YOUR-ATTRIBUTES}.
