Proceedings of the Third Conference "Wolfram Technologies" (SPbESU, 2015)
On June 9, 2015, the Third Wolfram Technology Conference was held at St. Petersburg State University of Economics (SPbHEU), which was attended by over 250 people. We are pleased to present its materials to you: this is a large number of speaker presentations, as well as their presentations, which you can download and study in detail, as well as use all the codes given in the reports in your work or hobby.
The conference examined a huge number of areas of knowledge: cloud computing, corporate solutions, modeling and simulation systems, computational finance, educational technologies, machine learning, computational geometry, data science, visualization, images, sound and signal processing, high-performance computing, publishing and education.
Keynote: Units of measurement, physical quantities and scientific data in Wolfram Language
Michael Trott | Chief Scientific Advisor, Wolfram | Alpha Research Groups
In his report, Michael talks about the concept of knowledge in the Wolfram Language, the Entity sublanguage for direct interaction with Wolfram | Alpha supervised databases, and also talks about the new functionality that will appear in the upcoming versions of the Wolfram Mathematica system: from the calculated Wolfram mathematical formula base Functions Site (contains over 300,000 formulas), up to anatomy data. At the end, Michael cites a huge number of interesting examples that use the knowledge bases built into Wolfram Language: from constructing the distribution of a possible monetary amount in a bag, if only its mass is known, to solving complex physical problems.

Manipulating structured data in Wolfram Mathematica (Wolfram Language)
Leonid Shifrin | Consultant, Advanced Research Group, Wolfram Research
Leonid talks about the database format built in Wolfram Language - Dataset and Association , as well as the functionality he develops for the kernel: lazy lists (lazy lists) that allow working with objects of arbitrary size (several terabytes) directly in the Wolfram Mathematica front end, which allows solving Big Data tasks much more efficiently.
