我使用Microsoft Academic API的graph search方法使用以下查询按ID检索论​​文:

{
    "path": "/paper",
    "paper": {
        "type": "Paper",
        "id": [2557283755],
        "select": [
            "PublishYear",
            "CitationCount",
            "OriginalTitle",
            "NormalizedTitle",
            "DOI"
        ]
    }
}

我遇到的问题是,对于某些论文,响应完全是空的,即使我通过用户界面查找论文时,它也有完整的元数据。例如,尝试通过API检索this paper会产生

{
    "Results": [
        [
            {
                "CellID": 2557283755,
                "PublishYear": "",
                "CitationCount": "",
                "OriginalTitle": "",
                "NormalizedTitle": "",
                "DOI": ""
            }
        ]
    ]
}

而对于另一篇论文,答案是正确的:

{
    "Results": [
        [
            {
                "CellID": 2112796928,
                "PublishYear": "1998",
                "CitationCount": "135",
                "OriginalTitle": "Gradient-based learning applied to document recognition",
                "NormalizedTitle": "gradient based learning applied to document recognition",
                "DOI": "10.1109/5.726791"
            }
        ]
    ]
}

有没有人有这方面的经验?对我而言,它看起来像是数据库中的错误,但我想确保它不是与我的查询相关的东西。谢谢!

问题是由数据版本差异引起的。图搜索方法使用的学术图数据集的版本可能与Microsoft Academic门户https://academic.microsoft.com的版本不同。我们正在部署新的数据管道,以使版本差异尽可能小。
