Question

我正在寻找某种方法来检索某个关键字（也是主题）的所有相关主题。例如，对于关键字“ Pizza”，我想要得到类似的内容：[“ Food”，“ Italian”，“ Cheese” ....]。有什么办法可以使用Wikipedia API？谢谢！

最容易想到的是文章类别。有关如何使用API检索它们的信息，请参阅API:Categories。例如，文章pizza具有以下non-hidden类别：

{
    "continue": {
        "clcontinue": "24768|Popular_culture",
        "continue": "||"
    },
    "query": {
        "pages": {
            "24768": {
                "pageid": 24768,
                "ns": 0,
                "title": "Pizza",
                "categories": [
                    {
                        "ns": 14,
                        "title": "Category:Cheese dishes"
                    },
                    {
                        "ns": 14,
                        "title": "Category:Convenience foods"
                    },
                    {
                        "ns": 14,
                        "title": "Category:Flatbread dishes"
                    },
                    {
                        "ns": 14,
                        "title": "Category:Greek inventions"
                    },
                    {
                        "ns": 14,
                        "title": "Category:Italian-American cuisine"
                    },
                    {
                        "ns": 14,
                        "title": "Category:Italian cuisine"
                    },
                    {
                        "ns": 14,
                        "title": "Category:Italian inventions"
                    },
                    {
                        "ns": 14,
                        "title": "Category:Mediterranean cuisine"
                    },
                    {
                        "ns": 14,
                        "title": "Category:National dishes"
                    },
                    {
                        "ns": 14,
                        "title": "Category:Pizza"
                    }
                ]
            }
        }
    }
}

您可以通过https://en.wikipedia.org/w/api.php?action=query&prop=categories&titles=Pizza&clshow=!hidden进行检索。

与dog类似：https://en.wikipedia.org/w/api.php?action=query&prop=categories&titles=Dog&clshow=!hidden
