查询DBpedia以获取不同输入的摘要 [英] Query DBpedia to get abstract for different inputs

问题描述

我有一个问题，我需要对DBpedia建立一个查询，这样，如果我输入其中任何一个作为输入，例如城市名称或人名，研究所名称或乐器名称，我可以得到其摘要为输出??? 例如， 纽约州-纽约州是美国东北和中大西洋地区的州... 火星-火星是距太阳第四的行星，也是太阳系中第二小的行星. 迈克尔·杰克逊(Michael Jackson)-迈克尔·约瑟夫·杰克逊(Michael Joseph Jackson)是美国歌手，词曲作者，舞蹈演员和演员...

I have a question I need to build a single query to DBpedia such that, If I give any one of these as input like a City name or a person name or a Institute name or a Instrument name can I get its abstract as a output??? For instance, New York- New York is a state in the Northeastern and Mid-Atlantic regions of the United States...... Mars- Mars is the fourth planet from the Sun and the second smallest planet in the Solar System.... Michael Jackson- Michael Joseph Jackson was an American singer, songwriter, dancer, and actor......

我已经尝试过了，但是它并不适用于所有人.

I have tried but its not working for all.

 SELECT ?abstract WHERE { 
 <http://dbpedia.org/resource/New_York> 
 <http://dbpedia.org/ontology/abstract> 
 ?abstract
 FILTER langMatches(lang(?abstract), "en")
 }

推荐答案

如果要获取多个事物的摘要，请在VALUES块中提供这些多个事物.我发现?name的匹配对于基于名称的搜索足够有效.

If you intend to get the abstract for multiple things, supply those multiple things within a VALUES block. I found that matching by ?name worked sufficiently well for name-based searches.

SELECT DISTINCT ?abstract WHERE { 
  [ rdfs:label ?name
  ; dbpedia-owl:abstract ?abstract
  ] .
  FILTER langMatches(lang(?abstract),"en")
  VALUES ?name { "New York"@en }
}
LIMIT 10
