Microsoft Academic API searching by Title

Question

I am trying to use the Microsoft Academic Search API to find articles by title. As it is, I have a series of test titles, for instance, "Emotion detection for wheelchair navigation enhancement," an article I know appears precisely once, it does not appear in the API results.

Here is the URL call:

https://api.projectoxford.ai/academic/v1.0/evaluate?expr=Ti='Emotion detection for wheelchair navigation enhancement'&model=latest&count=1&offset=0&attributes=Ti,Y,AA.AfN,C.CN,J.JN,E

Here is the associated HTTP request:

GET https://api.projectoxford.ai/academic/v1.0/evaluate?expr=Ti='Emotion detection for wheelchair navigation enhancement'&model=latest&count=1&offset=0&attributes=Ti,Y,AA.AfN,C.CN,J.JN,E HTTP/1.1
Host: api.projectoxford.ai
Ocp-Apim-Subscription-Key: ••••••••••••••••••••••••••••••••

And these are the results I get:

apim-request-id: 1e0501f9-6398-4bd1-8a3d-36bff155bdd2
Strict-Transport-Security: max-age=31536000; includeSubDomains; preload

{
  "expr": "Ti='Emotion detection for wheelchair navigation enhancement'",
  "entities": []
}

With Ti parameter you should put all your text in lowercase and delete all special characters.

You should use E.DN parameter (an Extended Metadata Attributes) which is "Display Name of the paper" to have the full name of the paper (with uppercase and special characters).

try adding three dots at the end of 'Ti' that is,

Ti='Emotion detection for wheelchair navigation enhancement'...

I replicated your search and making the query string lowercase did the trick for me, so this works:

https://westus.api.cognitive.microsoft.com/academic/v1.0/evaluate?expr=Ti='emotion detection for wheelchair navigation enhancement'&model=latest&count=10&offset=0&attributes=Id

I couldn't find any references in the docs that explain this behaviour, please feel free to comment in case you do.
