Interactively Search & Visualize Your Big Data and NLP for Lucene

Join us for the monthly San Francisco Solr Meetup, with the below talks from Cloudera's Romain Rigaux and Lucene/Solr Committer, Koji Sekiguchi. Food and drinks will be provided.

Interactively Search and Visualize Your Big Data, Presented by Romain Rigaux, Cloudera

Open up your user base to the data! Contrary to programming and SQL, almost everybody knows how to search. This talk describes through an interactive demo based on open source Hue how users can graphically search their data in Hadoop. The underlying technical details of the application and its interaction with Apache Solr will be clarified.

The session will detail how to get started with data indexing in just a few clicks as well as explore several data analysis scenarios with the latest Solr Analytics Facets and Spark Streaming. Through a Web browser, attendees will be shown how to explore and visualize data for quick answers. The search dashboard in Hue, with its draggable charts and dynamic interface, lets any non-technical user look for documents or patterns.

Attendees of this talk will learn how to get started with interactive search visualization in their Solr cluster.

Speaker: Romain is the Lead of Hue and an engineer at Cloudera. Before he worked on distributed systems at Yahoo! and Google and has been building Web apps since the early days.

An Introduction to NLP4L: Natural Language Processing Tool for Apache Lucene, Presented by Koji Sekiguchi, RONDHUIT

NLP4L is a natural language processing tool for Apache Lucene written in Scala. The main objective of this OSS project is to use NLP technologies to improve Lucene users' search experience. There is a famous problem in IR field - the trade-off problem between precision and recall. They are incompatible. I will first mainly talk about how we try to solve this problem in our project. Then I will introduce to you our NLP4L Framework that we are currently developing. Moving forward, NLP4L will run on this Framework. Dictionaries that NLP4L created from corpus will be deployed to Solr via the Framework.

Speaker: Koji Sekiguchi is a Lucene/Solr committer and PMC member. He enrolled in the Japan Advanced Institute of Science and Technology in 2012 to major in natural language processing and received a master's degree in information science in 2014. He is the founder of RONDHUIT, an Apache Lucene/Solr consulting/training service provider based in Japan.
