我正在如下使用SPARQLWrapper
来运行我的wikidata查询。
from SPARQLWrapper import SPARQLWrapper, JSON
import pandas as pd
sparql = SPARQLWrapper("https://query.wikidata.org/sparql")
sparql.setQuery("""
SELECT DISTINCT ?item {
VALUES ?searchTerm { "word2vec" "fasttext" "natural language processing" "deep learning" "support vector machine" }
SERVICE wikibase:mwapi {
bd:serviceParam wikibase:api "EntitySearch".
bd:serviceParam wikibase:endpoint "www.wikidata.org".
bd:serviceParam wikibase:limit 3 .
bd:serviceParam mwapi:search ?searchTerm.
bd:serviceParam mwapi:language "en".
?item wikibase:apiOutputItem mwapi:item.
?num wikibase:apiOrdinal true.
}
?item (wdt:P279|wdt:P31) ?type
}
ORDER BY ?searchTerm ?num
""")
sparql.setReturnFormat(JSON)
results = sparql.query().convert()
results_df = pd.io.json.json_normalize(results['results']['bindings'])
print(results_df)
我想将单词列表"word2vec" "fasttext" "natural language processing" "deep learning" "support vector machine"
作为python列表。即如下。
mylist = ["word2vec", "fasttext", "natural language processing", "deep learning", "support vector machine"]
在这种情况下,如何将mylist
作为参数插入到上面已经提到的现有wikidata查询中。
我尝试如下使用f字符串。但是,它对我不起作用。
sparql.setQuery(f"
SELECT DISTINCT ?item {
VALUES ?searchTerm { {mylist} }
SERVICE wikibase:mwapi {
bd:serviceParam wikibase:api "EntitySearch".
bd:serviceParam wikibase:endpoint "www.wikidata.org".
bd:serviceParam wikibase:limit 3 .
bd:serviceParam mwapi:search ?searchTerm.
bd:serviceParam mwapi:language "en".
?item wikibase:apiOutputItem mwapi:item.
?num wikibase:apiOrdinal true.
}
?item (wdt:P279|wdt:P31) ?type
}
ORDER BY ?searchTerm ?num
")
很高兴在需要时提供更多详细信息。
