London Information Retrieval Meetup

We are pleased to announce the ninth London Information Retrieval Meetup, a free evening meetup aimed to Information Retrieval passionates and professionals who are curious to explore and discuss the latest trends in the field.
This time we go fully remote, given the COVID-19 situation and the impossibility of hosting the event live.
The evening will be structured with 2 technical talks, with Q&A session after each talk.

Lucene-grep

I’m going to present my pet project Lucene-grep. Lucene-grep is a multi-platform command-line full-text search tool that leverages Lucene to get the work done and have some fun while doing it.

My motivation behind Lucene-grep is to bring the awesomeness of Lucene to new places while making it simple to install and start hacking. This is an interesting task given that Lucene is a Java library that is viewed as old and just too complicated to hack with.

In the live coding session, I will show how to turn Lucene-grep from a simple full-text search tool e.g.
“`
echo “Lucene is awesome” | lmgrep “Lucene”
“`
into an alternative for the Elasticsearch Percolator.

Second talk

Eric Pugh

He is a member of the Apache Software Foundation and continues to be very active in the Solr and Tika projects, as well as avidly reads every commit to the Zeppelin project!  In biotech, financial services, and defense IT, he has helped European and American companies develop coherent strategies for embracing open source software. Eric became involved in Solr when he submitted the patch SOLR-284 for extracting text from binary files (such as PDF and MS Office formats), that subsequently became the single most popular patch as measured by votes!  He co-authored the book Apache Solr Enterprise Search Server, now on its third edition.  Today he helps OSC’s clients build their own search teams and improve their search maturity, both by leading projects and by acting as a trusted advisor.

Gathering Multiple Ratings w/ Quepid

At Haystack 2019, Tito Sierra and Tara Diedrichsen made the case for a Human Rated Testing program in improving search. https://haystackconf.com/2019/human-judgement/  

In this talk we’ll share an update on adding support for multiple judgements from multiple raters to Quepid, an open source tool for supporting HRT programs.   We’ll talk about some of the analytics to measure how aligned the raters are, and solicit feedback from the community on next steps.

Lastly, we’ll do some live rating with the audience, to demonstrate some of pitfalls of human judgements.

Join us for a free evening!
