Synonyms list plays an important part for search. However, it usually take a long time to detect and maintain synonyms by the search or ontology group in a company. In this talk, we will discuss how to automatically detect synonyms from user click data and compare with popular methods such as word2vec (which is able to find related word but not nessisarily interchangeable for search purposes). We will also demo how to generate those analytical results and use them to improve search relevancy by a system, which combines the power of Solr with the power of a fast distributed compute engine like Apache Spark, to bring data science into production.
