Wikidata entity value from name
Is there a way to get Wikidata page information based on the name of the entity for example if I wanted to get page data for Google. I think it has to be done using "entity" with the corresponding entity value however I am not sure of there is any easy way to determine the entity value.
Answer
If you want to do this using the API, you would first use wbsearchentities to find out which entity do you want. For example:
https://www.wikidata.org/w/api.php?action=wbsearchentities&search=Google&language=en
The problem with this is that there are multiple entities called "Google": the company (Google Inc.), the search engine (Google Web Search), the verb (to google) and even a Wikipedia disambiguation page.
After you somehow decide which entity to access, use wbgetentities to actually get the information you want:
https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q95&languages=en
Or, if you can't decide which entity to use, you could get information for all of them at the same time:
https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q95|Q9366|Q961680|Q1156923&languages=en
