sparql - 如何在Python中将wiki数据QID转换为实体，反之亦然

Question

我有从文本中提取的实体列表。

例如，这是我的文字

"text": "Anarchism is an anti-authoritarian political and social philosophy that rejects hierarchies deemed unjust and advocates their replacement with self-managed, self-governed societies based on voluntary, cooperative institutions."

这里是从文本中提取的实体。(对于每一对，第一个是实体，第二个是文本中提到的实体。

"anchored_et": [["Anti-authoritarianism", "anti-authoritarian"], ["Political philosophy", "political"], ["Social philosophy", "social philosophy"], ["Hierarchy", "hierarchies"], ["Workers' self-management", "self-managed"], ["Self-governance", "self-governed"], ["cooperative", "cooperative"]]

此外，我还有三元组列表，其主题和对象采用 wiki 数据 QID 格式。

所以我需要首先将提取的实体转换为其 QID，然后找到其主题所在的三元组，找到这些三元组后，我需要将对象 QID 转换为其实体。

所以我需要在 python 中将 wiki 数据 QID 转换为实体，反之亦然。

我的问题是我该如何做到这一点。

Answer 1

这是我为我编写的两个函数。

我用过SPARQLWrapper来自 pypi。

from SPARQLWrapper import SPARQLWrapper
import requests

def wikidata_id_to_enwiki_title(Qid):
    try:

        sparql = SPARQLWrapper("https://query.wikidata.org/sparql")
        sparql.setReturnFormat('json')

        sparql.setQuery('SELECT DISTINCT * WHERE { wd:'+Qid+' rdfs:label ?label . FILTER (langMatches( lang(?label), "EN" ) ) }') # the previous query as a literal string
        data=sparql.query().convert()
        results=data["results"]["bindings"]
        results=[res["label"]["value"] for res in results]
        return results

    except:
        return [ ]

def enwiki_title_to_wikidata_id(title: str) -> str:
    try:
        protocol = 'https'
        base_url = 'en.wikipedia.org/w/api.php'
        params = f'action=query&prop=pageprops&format=json&titles={title}'
        url = f'{protocol}://{base_url}?{params}'

        response = requests.get(url)
        json = response.json()
        for pages in json['query']['pages'].values():
            wikidata_id = pages['pageprops']['wikibase_item']
        return wikidata_id
    except:
        return None
