We invite you to go through the process of speaking proposal submission – necessary details you will find below.
The 8th edition of the annual conference Big Data Technology Warsaw Summit takes February 23-24th 2022. Due to the commonly known circumstances it will be organized as online interactive event.
More than 500 professionals will attend the conference to hear technical presentations given by dozens of speakers from top data-driven companies.

Big Data Technology Warsaw Summit 2022 is fast approaching.
Please save the date - February 23 - 24, 2022.
This time the conference will be organized as an online interactive event. This makes it easier for everyone to speak and attend because there is no need to travel to Warsaw.
As the Call for Presentation (CfP) is still open, we’d like to encourage you to submit your proposals. To shed some light on how submissions are rated and selected, we describe our evaluation process in this blog post.
The deadline for the CfP is October 10th, 2020 and the submission page is here.
Knowledge sharing is the main focus
First and foremost, we aim for presentations about case studies, technologies that solve real-world problems, best practices and lessons learned. We reject submissions containing outright sales pitches and commercial presentations.
In each submission we evaluate a presentation value, uniqueness of its subject, alignment with conference core and also speaker’s professional achievements.
- Value - We aim for the practical and helpful content. If attendees go back to work after the conference, they should be able to apply new knowledge and inspirations in their projects. Ideal presentations are based on real-world use-cases, that work in production at reasonable scale and bring value to the business.
- Alignment - The main goal of the conference is knowledge sharing. Everyone enjoys presentations where speakers openly talk about their use-cases, technology stack, lessons learned. The authentic goal of the presentation should be sharing the knowledge, not selling some product, software or services.
- Uniqueness - Although we aim for practical and useful content, we prioritize talks that haven’t been already presented at other conferences. There aren’t many videos or blog posts in the Internet explaining a particular topic, technology or use-cases in detail. Ideally, a speaker should present her/his unique perspective on a given topic and have her/his own comments to share.
- Speaker - We check if a speaker is known in the BigData / Cloud / ML community, has some prior speaking experience at conferences/meetups, what company she/he represents, and so on. We also give a small-percentage bonus point for diversity to get more speakers from any underrepresented groups.
You can check the agenda of the last edition of the conference and notice that many presentations score very high in each of these 4 criteria. Among top-rated presentations during the CfP process in 2019 were, for example, “Building Recommendation Platform for ESPN+ and Disney+. Lessons Learned”, “Presto @Zalando: A cloud journey for Europe’s leading online retailer”, “Reliability in ML - how to manage changes in data science projects?” or “Omnichannel Personalization as an example of creating data ROI - from separate use cases to operational complete data ecosystem”.
One more experimental track
There are several tracks at the conference and all of the criteria above apply to all conference tracks excluding one.
This year, as an experiment, we decided to launch a new track called “Academia, the incubating projects, and POCs”. Presentations submitted to this track will be scored in a standard way against the Alignment, Uniqueness and Speaker criteria, but we will not expect that submissions describe production use-cases or battle-proven technologies that work at large scale. However, we assume that listening to these presentations will still bring value to the audience by putting some technologies into their radars or introducing new techniques or use-cases that might be popular in the future.
The CfP committee that consists of practitioners
Our CfP committee is quite large and consists of experts who have practical experience in the data-related field and work at top data-driven companies. Each reviewer has her/his own area of expertise. Typically each reviewer rates presentations in multiple tracks, and she/he can specify the importance (weight) of her/his rating in each particular track (from 0.0 meaning no expertise, to 1.0 meaning a lot of expertise). For example, a reviewer who is a senior data engineer specializing in building real-time streaming solutions can rate two tracks (i.e. data engineering and real-time streaming analytics) and give them slightly different weights.
To minimize the risk of bad decisions, multiple reviewers rate each submission (4 reviewers on average) and discuss them. Typically, we add comments next to the ratings so that we share our findings, feedback, concerns across the committee. We assume it’s fine that someone can change her/his vote after hearing feedback from others. We want the CfP process to be a discussion where the CfP members collaborate together to select the best submissions.
The first round to build a short-list
In the first round, each committee member rates presentations in her/his track(s) in four categories and provides additional comments. Here is an example:
We calculate a score for each submission based on the ratings, criteria weights and reviewers expertise.
Then for each track, we build a quite large list of good-rated presentations. During this process, we have several discussions and iterations based on provided comments and other findings so that we can review each presentation as carefully as possible and re-review them again if needed.
Second round to avoid duplicates and move submissions between tracks
It happens that we have multiple submissions from the same speaker or from the same company. Often all of them get high scores because they are practical, unique, and aligned to the conference core. However, to build a more diverse agenda, we must avoid multiple presentations from the same company or about the same technology or about the same use-case. For example, two years ago we rejected very good submissions about Apache Flink to avoid too many talks about Flink in the real-time streaming analytics track and accepted a bit lower-rated presentation about Apache Apex to cover a more diverse set of stream processing technologies. A year ago, we had one speaker who sent us three very well-rated submissions, and we had to accept only one of them, even though two other ones scored better than other presentations that we accepted. Also two years ago, we had three submissions about automotive and self-driving cars and we had to reject at least one of them, even though all of them looked good.
Also, a given submission might fit multiple tracks, so in this round we also check if some submissions can be moved across the tracks in case a particular track is too crowded.
As you see, our process is not automated and it requires a lot of brainstorming to build the agenda.
In this round, we divide the short-list into two parts - the submissions that we accept now, and the waiting list.
Third round to give last-minute opportunities to speak
It turns out that each year a few speakers have to cancel their presentations a few days or weeks before the conference for various reasons. To find a proper replacement we ask speakers from the waiting list first if they can still speak at the conference.
Does this system work?
During the conference we ask the audience to score each attended presentation so that we collect the feedback about its quality. Thanks to that we can also check if the presentations accepted by the CfP committee were enjoyed by the audience.
Last time, 18 out of 33 presentations given at the conference received a very good score from the audience (average of at least 4.0 in the 1-5 scale). Let’s call them well-rated presentations. 2 out of 33 presentations received a quite bad score from the audience (lower than 3.0 on average). Let’s call them badly-rated presentations. Here are some stats:
- 10 out of 16 presentations that were accepted by us through the CfP process were well-rated presentations. None of them was a badly-rated presentation.
- 6 out of the top 8 highest-rated presentations from the CfP process were also well-rated by the audience.
In other words, if the CfP committee accepts a submission it will be most likely enjoyed by the audience, or at least it will not disappoint the audience. We are quite happy about these numbers, but of course we still see the room for improving our process.
See you soon!
