Some background about http://recsyschallenge.com
Abstract: Maria from Illusion Inc. recently told her colleague Recruiter-John that she needs an additional team member: "I'm looking for a new team member that can support us in building up our new search engine. Some experience with Lucene or other search technologies and some background in information retrieval would be cool!". Recruiter-John then did his work and redirected her message to the world: "We are searching for a Data Scientist who has a PhD in Computer Science or some related field, 5 years industry experience in building search engines with Lucene at large scale, is highly skilled in Elixir and Erlang and fits into our young, dynamic team…". Paul is currently searching for a job: "I am a Senior Software Engineer with more than 10 years of industry experience in Java, Scala, C++ and 15 other programming languages, familiar with technologies such as Solr, Hadoop, Pig, Hive, Hbase, Cassandra, Riak, … I'm currently looking for a job where I can bring my dog to work." Bringing together the demand and offer on the job market is a non-trivial problem.
In this talk, we will share some of our frustration and will describe how we tackle this problem with recommender systems on XING, a career-oriented social network. We will give insights on the RecSys challenge (http://recsyschallenge.com) which is our attempt to let the bright minds of the RecSys community solve the recommendation problem that we failed to solve properly over the past four years. :-)
