Re: Cosine Similarity ElasticSearch
Hello Rick , MLT query translates the source document into a normal boolean terms query. This query is fired against the index and a normal TF IDF is used to find the score. AFAIK this is the working of MLT. Thanks Vineeth On Fri, Aug 1, 2014 at 2:11 PM, RickDast chicco...@gmail.com wrote: There is someone that can help us?

Re: Cosine Similarity ElasticSearch
Hi, I found some native script codings from Igor Motov here: https://github.com/imotov/elasticsearch-native-script-example/blob/master/src/main/java/org/elasticsearch/examples/nativescript/script/CosineSimilarityScoreScript.java and now playing with it Alex On Friday, August 1, 2014 11:53:24 AM UTC+3, Federico Bianchi wrote: There is someone that can help us?

Re: Cosine Similarity ElasticSearch
I am also interested in this question. I have found a fairly old code snippet [1] to calculate the cosine similarity in lucene, but I was wondering if elasticsearch provided an easier API to access this information. [1] http://sujitpal.blogspot.ch/2011/10/computing-document-similarity-using.html Hi, I'm using elasticsearch to index documents and then, with an other document, I score similarity using the more_like_this query. Just two questions: Does the more_like_this query use cosine similarity to score documents (I've read the documentation, but I'm still not sure)? There is a way to get the scores between 0 and 1?
