October 2023 kicked off with an incredibly busy week, full of events including the 8th annual HPCC Systems Poster competition, the 10th annual HPCC Systems Community Day Summit, and a series of free ECL workshops to help attendees explore the platform deeper. The purpose of the Summit is to gather engineers, data scientists and technology professionals to share knowledge and future roadmap plans for the HPCC Systems platform. This event is dedicated to showcase our community and have industry and academia present their HPCC Systems use cases, research projects and share their experience on how they leverage the HPCC Systems platform. Below you will find some of the standout moments and highlights from these events.

HPCC Systems Poster Competition

The 8th annual poster presentations competition was held as part of the Community Virtual Summit, showcasing the work of our academia community on how students leverage the HPCC Systems platform. In addition to the standard judged categories, the Community Choice Award was announced where our virtual attendees participated in the voting of their favorite poster. Winners were revealed as part of the Community Recognition and Awards ceremony.

This contest was run entirely remote. Posters were divided up into four categories, Data Analytics, Platform Enhancement, Use Case, and Research. Students submitted an abstract, their completed poster and a five minute video. A page on our Community Wiki was then created for each student, providing a space to access all these resources. At first the resources were only available to the judges, but once they had an opportunity to view them in private and make their decisions on the winners of the four categories, the posters were then made available for the public to view in our 2023 Poster Contest Wiki. The community then voted on their selection for the winner of the Community Choice Award.

Poster Competition Judges

In 2023, we had a great team of four judges that were assigned with a challenging task of evaluating each student’s poster and providing valuable feedback. If you recognize Amila, there is a good reason to it as she presented at the summit last year with a talk about PyHPCC. The same applies to Jeff Mao, who was an HPCC Systems Summer intern twice, and is now pursuing a computer science degree at Georgia Tech. He has also started his own startup in the e-commerce sector. Michael Gardner is a former intern and is now software engineer at LexisNexis Risk Solutions. Michael is a member of the HPCC Systems platform team playing a key role in the platform project builds. Finally, Mauricio Oliveira who is a manager of software engineering at LexisNexis Risk Solutions and also a former intern, now leads the technical development and support of data solutions for the Brazilian market. Thank you judges for volunteering your time to support the growth of our student community.

2023 HPCC Systems Community Summit:

Building Trustworthy and Auditable Digital Human Readers…

Machine Learning, Neural Networks and Large Language Models are statistical and opaque, human memory is fallible, and NLP++ is now stepping in to fix these problems and build trustworthy systems in areas such as law enforcement, healthcare, and sentiment analysis. Not only can NLP++ perform better than humans, but it can build systems that eventually can be better than human experts. Unlike the statistical methods of ML, NN, and LLM which are opaque and not auditable, NLP++ is a verifiable and auditable technology which is a game-changer in today’s critical systems. NLP++ is a glass box computer programming language and framework that seamlessly integrates with HPCC systems to provide sophisticated text processing that until now, have been only achievable by humans. We will look at work being done at Clemson to help solve the medical coding task that is currently done by human readers and has a 50% failure rate.

2023 HPCC Systems Community Summit:

Digital Human Readers Making History with NLP++ and HPCC Systems

From resume processing, to sentiment analysis, to digital dictionaries, NLP++ and HPCC Systems are making history. Searching for resumes is precarious when using simple keyword search and new work using NLP++ is making resume searching an exact science. Sentiment analysis till now has been done with statistical and keyword methods and have been too generic to used as real-world systems. Two sentiment analyzers break that mold, one involving soccer teams in Brazil, and the other cricket teams in India. NLP digital dictionaries have either been stuck in time for decades or are non-existent. Two Wiktionary projects use NLP++ to parse linguistic information from Wiktionary pages, processing hundreds of thousands and millions of pages using HPCC Systems, and creating dictionaries that can be used in future NLP systems. The result will be the most comprehensive English dictionary ever created for NLP and the first digital dictionary with linguistic information ever created for the Tamil language.

2023 HPCC Systems Community Summit:

Parquet Support for ECL

Introducing the Parquet Plugin, an interface between ECL and Apache Arrow that gives the ECL programmer the capability to interact with the parquet file format. This talk will demonstrate how ECL programmers can efficiently read and write parquet files with ease.  With this interface, ECL programmers can partition datasets, read any partitioned or non-partitioned dataset, and write to a parquet file. In the demo all the functions of the plugin will be shown. One of the key highlights of the plugin is its capability to handle datasets larger than memory. By leveraging streaming techniques, we ensure efficient processing of large-scale datasets without sacrificing performance or data integrity. Attendees will gain insights into the integration of parquet and how the Apache Arrow library was leveraged to give the ECL programmer efficient access to the parquet file format. A variety of demos to include usage examples will be shown as well as opportunities to ask questions and learn more about the plugin. 

HPCC Systems in Action

2023 HPCC Systems Community Summit:

Vulnerable Victim Monitoring – Connecting the Dots to Find…

According to Child Find of America, an estimated 2,300 children go missing each day. That equates to over half a million missing children per year. Most of these children are runaways, a population that is quite vulnerable to trafficking. Trafficked victims can be exploited for their PII in relation to account take over, stolen or synthetic identity fraud. LexisNexis Risk Solutions Inquiries are comprised of searches for fraud and credit seeking consumers which are stored in HPCC Systems.  These hundreds of billions of inquiry data can be searched retroactively and monitored proactively for matches on missing children within a reasonable geographic area. Additional topics of discussion will include data visualization capabilities in Python with data obtained from both the National Center for Missing & Exploited Children’s public RSS feed (current missing cases) as well as all missing cases from the past 20 years (obtained from the ADAM Program). We will also discuss proposals for additional future studies utilizing the power of HPCC Systems to extract other types of big data and provide further insights and information to provide law enforcement and social services to better aid them in the search and prevention of human trafficking.

HPCC Systems Community Day Summit Workshops


The HPCC Systems Training and Support team was very busy last year visiting universities and trade show events to promote HPCC Systems and ECL through Code Days, hackathons, and workshops. The 2023 Community Summit workshops presented an in-depth look at some of these events in three 1-hour sessions. Lead trainer Bob Foreman crafted each of these hackathons and then adapted them into workshop format for this event. Bob Foreman has worked with the HPCC Systems technology platform and the ECL programming language for over a decade and has been a technical trainer for over 30 years. He is the developer and designer of the HPCC Systems online training courses and is the senior instructor for all classroom and remote based training.

Part 1:

The “Music is Life!” Workshop

Who doesn’t love music? Take a break from your daily routine datasets and join us in this first hour. We break down a popular open-source music dataset, explore normalizing the dataset and its effects, and look at a variety of data evaluation and query techniques.

Part 2:

The “Find your Paradise” Hackathon

Have you ever thought about building an application that can help people find places to live that maximize their quality of life and happiness?
The goal of this challenge is to analyze different datasets across different categories and correlate them using the HPCC Systems platform. After analyzing, the participants are asked to design an interface to query this data and assign it a scoring system, then deliver it to the user via ROXIE and show the user where they should most likely want to live. Users should be given choices in an easy-to-use form that when submitted will generate a unique set of scores based on locations.

Part 3:

Better Customer Insights Through Relational Dataset Queries

In this final hour of our workshop series, we look at the power of the open data model, transforming normalized data into a denormalized relational dataset, and use the implicit relationality power to analyze relationships to provide better customer insights.
