# Commercial approaches to UPKD act like specialized search engines As far as I can tell, the commercial applications out there suggest possibly relevant papers, but leave it up to the reader to read through them and determine how they’re relevant or whether they’re relevant. They generally focus on finding the most relevant paper at a given moment. This is because [[Knowledge discovery is just not that useful]]. Examples are: * [[Iris.AI]] * [[Meta (Paper Discovery)]] which is a commercialized version of * [[Semantic Scholar]] * [[ContentMine]] * [[Metabus.org]] <!-- #evergreen --> [Web URL for this note](http://notes.benjaminreinhardt.com/Commercial+approaches+to+UPKD+act+like+specialized+search+engines) [Comment on this note](http://via.hypothes.is/http://notes.benjaminreinhardt.com/Commercial+approaches+to+UPKD+act+like+specialized+search+engines)
