Welcome Dan Urman – Lead Technical Support Engineer

Hi, folks! Dan here!

I’ve always been interested in psychology and technology. My first website was a bunch of personality tests from my high school psychology class implemented in JavaScript. These hobbies led me to a career in web development, but eventually I realized that the best part of my job was actually when I got to help colleagues solve whatever technical problems they’d run into in their own work. Because of that, I transitioned to technical product support and have never been happier.

Building websites is still a hobby of mine, and it’s given me frequent opportunity to lament how difficult it is to make use of the immense amount of human knowledge that exists on the internet. When I heard about Diffbot’s mission to collect and structure this knowledge to enable truly intelligent systems, I was immediately excited!

I’m thrilled to join Diffbot’s Technical Support Engineering team where I’ll be working to empower our customers to meet their goals and to improve the resources available to our developer community.

Welcome Oliver Lehmberg – Machine Learning Engineer

Hi! My name is Oliver and I am a new Machine Learning Engineer at Diffbot!

I am from Germany and I have always been passionate about computer science as well as how to use computers to automate everyday tasks. After obtaining my master’s degree in Business Informatics, I joined the Data and Web Science Group at the University of Mannheim, where I worked on the large-scale integration of tabular data from web sites and knowledge graphs for five years.

I finished my PhD this year and will now work with the research team at Diffbot. My work here will continue in the area of large-scale data integration and focus on record linking and sub-record linking. These are critical tasks for the construction of knowledge graphs, as they determine which pieces of information from different source web sites are combined into the same entity, and how such entities are interlinked with each other.

In my free time I like to travel around the world and spend time with friends and family. I look forward to my new adventures at Diffbot!

Welcome Tomer Balan – Senior Software Engineer

Hi there!

My name is Tomer, and I’m a new Senior Software Engineer at Diffbot! I am from Tel Aviv, Israel, a city with beautiful beaches, restaurants, bars, and a lot of technology.

As far back as I can remember, I have always been passionate about identifying and solving business problems using technology. For that reason, I chose to study Industrial and Management Engineering at Ben-Gurion University.

While working as a Data Solutions Engineer at eBay, I signed up for a Diffbot trial and was amazed by the product and technology. I found Diffbot’s technology to be helpful for many use-cases in the company. By day, I used the Analyze and Product API’s, and by night, I investigated the new Knowledge Graph. Diffbot helped eBay reduce 30% of its manual work which lowered expenses and saved time. As a former Diffbot customer, I was fortunate to have been able to develop a great connection with the CEO, Mike and the rest of the team.

I am proud to be one of the first customers to join the Diffbot team. One of my main responsibilities at Diffbot is to build tools that enable non-technical users to understand our technology. I will be working on some very exciting projects so stay tuned!

In my free time, you can find me playing poker (online and offline), playing volleyball on the beach, watching European soccer, hanging out with friends and traveling (17 countries and counting!).  

I look forward to my new adventures and challenges at Diffbot!

Welcome Priya Venkateshan – Senior Software Engineer

Hi, my name is Priya, and I’m a Senior Software Engineer at Diffbot.

I grew up in Bangalore, India, and since everyone around me was getting into programming, I did too; though I secretly wanted to be in medicine or journalism. However, thanks to the professors and peers at NITK Surathkal, I discovered machine learning, got really into it, and was soon trying to learn information retrieval concepts from grainy MIT OpenCourseWare videos. Soon after, I enrolled in UC Irvine’s master’s program in Computer Science and enjoyed the wide variety of cutting-edge courses in machine learning concepts. During my time there, I worked on a thesis involving graphical models for coreference resolution.

My experience in the industry, especially on eCommerce data, has taught me about the importance of domain knowledge and scale in making machine learning models useful in a real-world context, as well as given me an interest in best practices regarding supporting data and models in production. Prior to Diffbot, I worked at eBay, where we crawled product websites to augment the eBay catalog. Diffbot was one of the tools our organization used towards this goal. Having worked on web crawling and data extraction in a specific domain, it is exciting to work on the generalized version of those problems at Diffbot, especially since I get to impact a state-of-the-art, commercial knowledge graph and work with some of the best minds focused on these problems.

I write and edit fiction in my spare time, where I use technology to make life easier for fiction writers.

Welcome Joone Hur – Software Engineer

Hello everyone! 

My name is Joone, and I am a new Software Engineer at Diffbot where I own the renderability and performance of the rendering farm here. For many years, I worked on web engines such as Gecko, WebKit and Chromium at Samsung and Intel Open Source Technology Center. Currently, I am pursuing a new adventure with a machine learning company.

Human beings have advanced with the internet. We can easily share information and communicate with anyone in the world, but sometimes we face issues such as the information being impermanent and inaccurate. Also, it is still hard to find information from the web even though we have good search engines and Wikipedia. In fact, they have not changed much since they were invented. Diffbot is building a knowledge graph that will be the future of human knowledge, which motivated me to join. Essentially, my role here is to make the web machine readable for our machine learning systems. I have also studied data mining using neural networks for my Masters degree which will help when working with our researchers.

In my free time, I’m a professional comic artist, and I post my comics about free/open source software at https://joone.net. If I have the chance, I will draw comics about machine learning and Diffbot’s services. Stay tuned for our blogs and follow us on Twitter!

Welcome Dimitris Kontokostas – Software Engineer

Hello there! I am Dimitris, and I am a new Software Engineer at Diffbot!

As the name implies, I am Greek. In particular, I am from the northern part of the mainland (far away from the beautiful beaches). I hold a degree in Electronics & Computer Engineering from the Technical University of Crete, a MSc in Web Science from Aristotle University of Thessaloniki, and a PhD on Large-scale Knowledge Extraction & Quality Assessment from the University of Leipzig. Through my MSc and PhD programs, I was exposed to knowledge graphs and felt really fascinated by the field. I have been working with knowledge graphs for almost 10 years now, and I am still amazed by the new possibilities they can unlock.

The Diffbot Knowledge Graph is really intriguing. It operates on web-scale using state of the art research on knowledge extraction and expands way beyond notable entities (e.g. celebrities, established companies, etc) that most knowledge graphs are limited to. I felt this was a perfect match for my research and professional skills and a great challenge to work on. My primary focus at Diffbot will be data quality and knowledge fusion. I will extend existing approaches and create new techniques to further improve & evaluate the accuracy of our knowledge graph.

In my free time, I enjoy spending time with family & friends, playing basketball, running and skiing.

I look forward to my new knowledge graph adventures at Diffbot!

Welcome Julia Wiedmann – Machine Learning Engineer (Research)

 

Hi there! My name is Julia and I am a Machine Learning Research Engineer at Diffbot.

Born and raised in Vienna, Austria, I moved to London to study Business. While I enjoyed my degree, I realized I was much more interested in technology, so I taught myself enough coding and math to qualify for a Masters degree in Computer Science at University College London (UCL). I recently finished my PhD at the University of Oxford, primarily developing new methods for machine learning-based web data extraction which can extract data from new pages at scale and without site-level supervision. My research interests widely overlap with Diffbot’s work, so I interned here last summer building the EventsAPI. The EventsAPI is a new addition to the Automatic API’s, which automatically extracts events from the open web. This allows events to be added to the Diffbot Knowledge Graph and customers to use the API directly. Now as an excited full timer, I am focusing on improving and expanding the Automatic API extraction methods.

In my free time I love all sorts of sports, such as cycling, skiing, hiking, and running.

I look forward to more adventures at Diffbot!

 

Welcome Lorenzo Torres – Technical Sourcer

I received my Bachelor’s Degree from University of Southern California (Fight On!) and then became a food truck driver and manager for a waffle dessert company in Pasadena, CA called Waffles de Liege. After 3 years, I felt that I wasn’t doing anything fulfilling and realized that I wanted to make an impact and difference in people’s lives. I left the industry and spoke to friends and family about the next career. They had mentioned recruiting and how it can change a person’s a life, as well as make a difference in the proper field. I went to various recruiting networking events and created my position with a start up called FabFitFun via their “create your job” submission. Impressed by my background, they hired me as an intern and then converted me full time into a Recruiting Coordinator. From there, I went to Robert Half for half a year for legal recruiting, and then a smaller tech recruiting agency called Strategic Employment Partners for Technical Sourcing. With minimal sourcing knowledge and only 7 months into the company, I received the 2017 Recruiter of the Year Award. I was then transferred to their New York branch, and once again received the 2018 Recruiter of the Year Award. I now find myself for the first time in an in house Technical Sourcer position with an awesome team, product, and company vision I can truly be behind.

Outside of work, I love to sing with friends and family via covers online and sometimes karaoke (was in choir when I was 10 years old all the way up to 19, and also trained formally), eating a lot (trying new restaurants and cooking), watching WWE/UFC/anything entertaining, play Dance Dance Revolution (used to compete), and just having a good ole time with friends and family.

I’m excited to help grow out the teams here in Diffbot, and can’t wait for what the future holds for all of us.

Welcome Paramita Mirza – Machine Learning Engineer Intern

 

Hello there! I’m Paramita (sounds similar to ‘parameter’) and I’m excited to be part of the Relation Extraction research team at Diffbot.

I received my PhD degree from the University of Trento/FBK-ICT in spring 2016. Under the supervision of Sara Tonelli, my PhD research focused on extracting temporal and causal relations between events from natural language texts, as part of the NewsReader project. I then joined Gerhard Weikum‘s group at Max Planck Institute for Informatics, where YAGO (Yet Another Great Ontology) Knowledge Base was developed, as a Postdoc. My research interests have always been revolved around Information Extraction and Machine Learning approach for it, making sense of unstructured text and building structured knowledge out of it. 

I learned more about Diffbot when I attended ISWC’18 in Monterey, and found out that they’re on their steadfastly way on building a gigantic knowledge graph out of the whole web. I got hooked and decided to temporarily escape rainy Germany to sunny California. Here at Diffbot, I’ll be working on extracting temporal qualifiers for facts extracted to build Diffbot Knowledge Graph, making sure that we can differentiate fresh facts from the historical ones. I would love to hear your ideas and suggestions on how to make that happen!
