Word2Vec model to generate synonyms on the fly in Apache Lucene [Berlin Buzzwords]

June 14 @ 2:50 pm - 3:30 pm

Berlin Buzzwords is a conference focused on open source software projects in the field of big data analysis, scalability, storage and searchability. It provides a platform for developers, engineers, IT architects, analysts and data scientists who are interested in information retrieval, the searchability of large amounts of data, NoSQL and big data processing.

//THE TALK

Word2Vec model to generate synonyms on the fly in Apache Lucene

Schedule: 14th June, 2:50–3:30 GMT +2
location: Berlin, Kulturbrauerei, Kesselhaus

If you want to expand your query/documents with synonyms in Apache Lucene, you need to have a predefined file containing the list of terms that share the same semantic.
It’s not always easy to find a list of basic synonyms for a language and, even if you find it, this doesn’t necessarily match with your contextual domain.
The term “daemon” in the domain of operating system articles is not a synonym of “devil” but it’s closer to the term “process”.
Word2Vec is a two-layer neural network that takes as input a text and outputs a vector representation for each word in the dictionary.
Two words with similar meanings are identified with two vectors close to each other.
This talk explores our contribution to Apache Lucene that integrates this technique with the text analysis pipeline.
We will show how you can automatically generate synonyms on the fly from an Apache Lucene index and how you can use this new feature along with Apache Solr with practical examples!
