In the last few days (4 days) I am getting a 400 when calling the Evaluate API (rest) via POST.
The response is always :
{
"Error": {

"Id": "d316da3c-9198-40aa-afd5-214a3b894c66",

"Code": "System.AggregateException",

"Message": "One or more errors occurred.",

"InnerErrors": [{

  "Id": "a98b1f72-7f09-4b44-961f-3335f3a8a3cb",

  "Code": "System.ArgumentException",

  "Message": "Offset must be an integer"

}, {

  "Id": "22e375c5-3506-447b-9bdb-943930938be9",

  "Code": "System.ArgumentException",

  "Message": "Count must be an integer"

}]

}
}

A month ago, if I made this request:

params = {'expr': 'Composite(AA.AuId=120559464)', 'attributes': 'Id,E.DN'}

I'd get back:

{

'logprob': -19.012,

'prob': 5.5359647e-09,

'Id': 2036161137, 

'DN': 'Extracellular vesicles as drug delivery systems : lessons from the liposome field',

'PK': 2036161137

}

Now, the Display Name (DN) is missing. This is not the first time metadata has gone missing; it was AWOL in February and March as well. See https://github.com/MicrosoftDocs/azure-docs/issues/24799

Will this be fixed?

When searching for an AuN in evaluate, doubling single quote does not work for people with apostrophes - it returns an error. This is a huge problem for us - is there a workaround?

Thanks very much for providing this service, but I really want to know some critical information such as how many quest per second/minute, how many quest per day/week/month, or is there a limit of total response size?

Please also note these information in document, thanks.

Please bring back graphSearch online - it has been down for several days. The server replies:

{ "statusCode": 500, "message": "Internal server error", "activityId": "8366f920-6ab6-40b1-8956-ce3171eb49ec" }

The following queries shown in the documentation (https://docs.microsoft.com/en-us/azure/cognitive-services/academic-knowledge/queryexpressionsyntax) do not work:

Ti='indexing by latent seman'...
Composite(AA.AuN='sue du'...)

However the numeric version does work:

Y='19'...

Being able to query strings via a prefix value would be really useful.

In the Evaluate API endpoint, we should be able to query based on Entity Type
i.e. the following API call:
https://api.labs.cognitive.microsoft.com/academic/v1.0/evaluate?expr=Composite(Ty=0)

should return results which are 'book's

After the 500 errors last week, my script is no longer returning results. It seems the api changed from right under me. I wish I had been notified. I paid for support, but they has been of little help. Can you communicate changes to the API?

I am interested in finding papers that quote exactly the text "Ecopath with Ecosim", not papers that contain the words 'Ecosim' and 'with' and 'Ecosim' because that may return irrelevant publications.

IE - specific titles.

Please bring this APi back , it is down from last 2-3 weeks.

can you add more attributes for affiliation, such as type (university, corporation, non-profit, hospital, government, ...), and their addresses populated at least with country?

In the Evaluate API endpoint, we should be able to query based on Entity Type
i.e. the following API call:
https://api.labs.cognitive.microsoft.com/academic/v1.0/evaluate?expr=Id=1500058340

should return the entity 1500058340

In the "Author" entity, List<uint> AffiliationID can contain many duplicates. This dramatically slows down query time.
From the example query below you can immediately see the Entity ID '1341412227' being repeated over 30 times--ridiculous.
{

"path": "/author",

"author": {

    "type": "Author",

    "match": {"DisplayAuthorName": "Chiao-Fe Shu"},

    "select": [ "DisplayAuthorName", "AffiliationIDs" ],

    "return": {}

}

}

Hi,
Is this service still operational? I'm receiving a 401 access denied when trying to hit any of the API endpoints. I made a stackoverflow issue here: https://stackoverflow.com/questions/50383519/microsoft-cognitive-services-subscription-not-working?noredirect=1#comment87783297_50383519

Thanks!

Oops. Something went wrong ... sorry
An unhandled exception has occurred and the request was terminated. Please refresh the page. If the error persists, go back

The call to POST /graph/search returns 500 in the API testing console here: https://westus.dev.cognitive.microsoft.com/docs/services/56332331778daf02acc0a50b/operations/57e3569ddbe2d91158fa270e/console.

I've also mentioned this issue here: https://github.com/Microsoft/azure-docs/pull/1964

How do we use the free access (granted to an academic institution) to apply DreamSpark credits to the Academic API?

It seems that for some searches on Microsoft academic API (and Microsoft's own web portal), the top result (in terms of relevance and citations count) is absent.

For example, search for "topological insulators". The top result, correctly given by Google scholar, is the most cited review article in the field, from 2010 (7454 citations), titled Colloquium: topological insulators​. ​ ​
​In Microsoft's academic however, there is no mention of this seminal article no matter if you order results by relevance or by citations.
How can that be?

Please enable ability to search(bing like) without specific a particular data field.
