I could see DBPedia is missing very important mobile phone list. They exist in Wikipedia but not in DBPedia, e.g. OnePlus series, Micromax Yureka , Moto g4

I'm refering this link: http://live.dbpedia.org/page/Smartphone

Does it mean that it is not yet ready to be used for critical usage - say a customer related project?

  • Shouldn't you ask this question at DBPedia?

  • Data quality depends on the effort you are willing put into this. An alternative strategy would be to search for smartphone manufacturers, and then (for each of them) for their products, maybe with a SPARQL query.

  • Yes, DBPedia, being updated once per 6 months is definitely not ready for "critical usage" - it would have been all too easy otherwise, no?

  • Wikidata might be more up-to-date.

DBpedia (http://dbpedia.org/sparql) holds a static dataset, updated in batches roughly every 6-12 months. Changes made on Wikipedia will eventually show up here.

DBpedia-Live (http://live.dbpedia.org/sparql) holds a dynamic dataset, updated from the Wikipedia firehose on a near-constant basis. Changes made on Wikipedia generally show up here within hours if not seconds.

Wikipedia (and hence, derived DBpedia and DBpedia-Live) data is messy, and often lacks the specific detail you want, especially in the structured data block. For instance, the YU Yureka (not the "Micromax Yureka") does not have a Type: Smartphone entry, unlike, for instance, the Xiaomi Mi 2S.

The solution to your complaint is to update Wikipedia content, and then wait for DBpedia-Live to pick up your changes.
