My name is Slava Novgorodov, Ph.D. and Computer Science Researcher.
I am Research Scientist at Meta (Facebook).
I obtained my Ph.D. in Computer Science from Tel Aviv University, under supervision of Prof. Tova Milo.
I am also a visiting lecturer at Tel Aviv University, teaching several courses.
I have different hobbies like learning languages, collecting soccer jerseys and traveling around the world.
Recent updates:
SIGMOD'25, The Web Conference'25 and SIGIR eCom'25 papers were accpeted.
Research
Currently I am Research Scientist at Meta, and most of my current projects are connected to the e-commerce. Mainly my focus is text analsysis and NLP research related to the e-commerce applications.
Prior to Meta, I worked at eBay Research as Applied Research Sceintist and before I was in different e-commerce related companies as Software Engineer and Data Scientist and also did research. I strated doing research during my B.Sc. studies in Mathematics and Computer Science when I joined the Data Management Research Group of Tel Aviv University (supervised by Prof. Tova Milo) as an intern. After finishing my B.Sc. in 2011, I continued to M.Sc. in Computer Science (which I finished in February 2014) and Ph.D. in Computer Science (2014-2018), all supervised by Prof. Milo.
During my master's studies I mainly worked on combination of crowdsourcing and web data management.
My M.Sc. thesis title was "Asking the Right Questions in Crowd Data Sourcing".
After working with the regular crowd, I started my research about crowdsourcing with experts. During my Ph.D. I worked mainly on "Data Cleaning using Experts" and "Rules Refinement and Sharing between Experts" projects.
The title of my Ph.D. thesis is "Experts in the Loop in Data Management".

Important dates
I was born in November 1989, in Russia (Soviet Union). I moved to Israel in September 2001.
In December 2009 I married my lovely wife Yana, and in October 2011 my first son, Dennis, was born.
In February 2017 my second and third kids, Alice and Tom, joined the family.
Industrial experience
In September 2006, my first job was IsraDon - largest Russian bookstore chain in Israel. My goal was clear - to define, design and implement the IT infrastructure from scratch. I started from buying equipment (computers, printers, barcode scanners, routers & switches), and then moved to the most important part - developing ERP software. I decided to develop a web-based application
(mainly because of my passion to the web), using PHP & MySQL as a backend and HTML, CSS, JavaScript and Ajax for the frontend.
After finishing developing and deploying the system, my responsibility was managing it and adding a new features.
I had a great time there, but in the end of 2009 I decided to move on.
In January 2010 I started my work in VisionMap -
a leading provider of digital mapping systems. I joined the Software Infrastructure Team as a C++ developer,
and my responsibilities were developing and deploying the best infrastructure for all software developers of VisionMap. It includes
bringing the latest version of C++ libraries and tools to the codebase (boost, Qt, OpenCV, Visual Studio),
switching all of our projects to support Unicode (personally, I believe in UTF-8 everywhere),
managing and upgrading the continuous integration server, source control, review board and a company's wiki.
In addition, I was developing digital mapping applications using our own infrastructure.
In October 2014 I moved to Linicom - a company that develops platform for online advertising and served as a Chief Scientist. I joined Linicom as a part time Research & Development consultant already in November 2013, and during the time I worked on different projects, until October 2014, when I started to work as Head of R&D, managing development and reasearch proccess in the company. This work included leading of user behaviour research, including better ads targeting and better user experience.
Starting January 2016 I moved to the Chief Scientist position and focused on the Data Science research - from prototype to production. We had different research projects, including Information Extraction, Recommendation Systems, Natural Language Processing and Web Data Management in general.
In January 2017 I joined Twiggle that develops a Natural Language search for e-commerces as a Senior NLP Engineer and Data Scientist. I spent first couple of month in the NLP team, developing features for better search queries understanding, and in parallel learning company's internal proccesses. Later, I moved to the Data Infrastructure team, as the first Data Scientist in the team. I was responsible for researching and developing automatic tools for matching customers data (product catalogs) to Twiggle's Knowledge Graph (Ontology), and fast customers onboarding. In addition, I was working on data-driven tools for semi-automatic knowledge creation, and search results improvements. Finally, I have participated in several innovation and strategic data-related projects.
In September 2018 I joined eBay Research as Applied Research Scientist were I worked on various NLP and ML project that are aimed to improve understanding of products data, estimating its quality and making eBay's catalog cleaner and better. During my work at eBay Research I also published 10+ research papers related to the e-commerce.
Starting March 2022 I work at Meta as Research Scientist.
Hobbies
In addition to my research and work, I have several hobbies.
First of them is strongly related to football:
I started collecting football teams shirts (jerseys)
from around the world, each of them having their own story. Later, I decided to focus only on CSKA Moscow (match worn) shirts.
I have one of the biggest collections of CSKA Moscow shirts (web-site will be available soon).
I also collect football balls and football teams scarfs. And of course, I play and watch football.
A second hobby of mine is learning languages:
As most of people that came to Israel from Russia, I have 3 main languages that I speak: Russian, Hebrew and English.
I spent some time learning Arabic, one of the most spoken languages in the world and also specificly very popular in the Middle East. Currently, I consider it as my fourth strongest language.
I studied Serbo-Croatian which is a beatiful slavic language, spoken by almost 20 million people, mostly in ex-Yugoslavian republics.
There are lots of great music, movies and books in this language.
I also have some basic knowledge and experience with Spanish. On the slavic languages axis I "played" with Polish and Czech.
The third one is connected to the previous two - traveling around the world:
After moving to Israel in 2001, I have visited different countries and places.
For some of them I studied a new language, and from part of them I bring football jerseys.
