How to query microsoft academic graph for citation and co-citation? - api

Question

Reading through:
https://www.microsoft.com/cognitive-services/en-us/Academic-Knowledge-API/documentation/GraphSearchMethod
It is a bit obscure the meaning of "path":
"path": "/paper/AuthorIDs/author" - I don't see authorIds object in the returned results.
# post data query
{
"path": "/paper/AuthorIDs/author",
"paper": {
"type": "Paper",
"NormalizedTitle": "graph engine",
"select": [
"OriginalTitle"
]
},
"author": {
"return": {
"type": "Author",
"Name": "bin shao"
}
}
}
#results
{
"Results": [
[
{
"CellID": 2160459668,
"OriginalTitle": "Trinity: a distributed graph engine on a memory cloud"
},
{
"CellID": 2093502026
}
],
[
{
"CellID": 2171539317,
"OriginalTitle": "A distributed graph engine for web scale RDF data"
},
{
"CellID": 2093502026
}
],
[
{
"CellID": 2411554868,
"OriginalTitle": "A distributed graph engine for web scale RDF data"
},
{
"CellID": 2093502026
}
],
[
{
"CellID": 73304046,
"OriginalTitle": "The Trinity graph engine"
},
{
"CellID": 2093502026
}
]
]
}
Which is the correct path (or data to post) to query for citation and co-citation of an article, and paginate results?

Answer 1

You will find AuthorIDs on the graph schema from Microsoft Academic Search:

Answer 2

Assuming you know the ID of the source paper (2118322263 in the following example), here is the POST part of the request:
{
"path": "/paper/CitationIDs/citation",
"paper": {
"type": "Paper",
"id": [ 2118322263 ],
"select": [
"OriginalTitle"
]
},
"citation": {
"return": {
"type": "Paper"
},
"select": [
"OriginalTitle"
]
}
}
This returns 634 results in one response, while a query to the paper itself shows a citation count of 732. I have no idea why there is a difference, nor how to do pagination.
