London Information Retrieval Meetup (December 2020)

london information retrieval meetup

We are so happy to announce the seventh 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 1 technical talk followed by a Q&A session with questions from the audience chosen (add your question as a comment to the event!). The meetup will end with a networking session.



After a short welcome & latest news speech from our Founder Alessandro Benedetti, we will proceed to the first talk.

Enriching postal addresses with Elastic stack

Most of the time postal addresses from our customers or users are not very well formatted or defined in our information systems. And it can become a nightmare if you are a call center employee for example and want to find a customer by its address. Imagine as well how a sales service could easily put on a map where are located the customers and where they can open a new shop…
Let’s take a simple example:

  "name": "Joe Smith",
  "address": {
    "number": "23",
    "street_name": "r verdiere",
    "city": "rochelle",
    "country": "France"

Or the opposite. I do have the coordinates but I can’t tell what is the postal address corresponding to it:

  "name": "Joe Smith",
  "location": {
    "lat": 46.15735,
    "lon": -1.1551

In this live coding session, I will show you how to solve all those questions using the Elastic stack with a lot of focus on Logstash and Elasticsearch.

Ilaria Petreti


Ilaria is a Data Scientist passionate about the world of Artificial Intelligence.She got a Master in Data Science, strongly believing in the power of Big Data and Digital Transformation. Thanks to the practical application on Flight Delay Prediction developed during her thesis work, she implemented several Data Mining and Machine Learning techniques and became familiar with the programming language R. She is also involved in a Research Project, deepening her knowledge about Ensemble Learning, with a specific focus on the Super Learner algorithm.

Anna Ruggero


Anna Ruggero is a software engineer passionate about Information Retrieval and Data Mining.
She loves to find new solutions to problems, suggesting and testing new ideas, especially those that concern the integration of machine learning techniques into information retrieval systems.
Anna came into contact with search engines during her studies falling in love with this world, therefore she decided to investigate this topic further participating to the 12th European Summer School in Information Retrieval and doing her master degree dissertation on Entity Search.
Thanks to this path, she has expanded and improved her knowledges of Java and Python languages, information retrieval systems, clustering and word embeddings.
