TOMSK, Oct 9 –
RIA Tomsk. To issue a list of suitable professions,
to identify the most popular graduate on Wikipedia, to distinguish extrovert
from introvert - this can be done using big data. What big data is and where
they are in ordinary life – head of the TSU
educational and scientific laboratory of computer learning tools at TSU Artyom
He had a lecture on the TSU Youtube channel as part of
the NAUKA 0+ festival. Theses of the lecture - in the review of RIA Tomsk.
Earlier it was reported that the festival takes place
in Tomsk from October 4 to 8. Its program includes about 70 events - lectures
from Tomsk scientists, podcasts about science, excursions to scientific
laboratories, scientific shows, quests, competitions and creative workshops.
What is big data?
"Big data is when data are more than one
terabyte, this is data that does not fit in Excel, data that cannot be
processed on the one computer. There is an opinion that big data is generally
any data, and also that big data does not exist at all - they say, this term
was invented by marketers," Feschenko says.

There are a lot of definitions of this phenomenon, and
they all depend on the context and scope of activity, the expert of TSU says.
He stressed that data sources were diverse. Thanks to digitalization and the
emergence of technologies that allow a person to easily and quickly publish
various information on the Internet, world data are doubled in their volume not
even daily, but in a shorter period of time.
"It turns out an abyss of information into which
humanity plunges day after day. And there is user data in this abyss -
these are all our actions, digital reactions that we produce while in digital
space. Even simple registration on a social network and the creation of a
half-empty account is already an artifact that we leave behind in the virtual
world," the scientist explains.
Big data under the magnifying glass
Center for Applied Big Data Analysis was created at
TSU to study big data, including user data in 2016. Every year it grows in the
skills and competencies available when working with big data, in the number of
tasks and projects.
"TSU Center is not the only example where
scientists are trying to benefit from a huge amount of data. So, a consortium
of universities has appeared, the purpose of which is to join forces, exchange
data, skills and technologies to extract these data," Feschenko says.

One of the areas of research of the consortium
scientists is a project related to measuring the third role of the university,
that is, its impact on the economy, the level of human capital and the
innovative potential of the region. Within its framework, among other things,
experts found out which famous graduates of the university are the most
"viewed" on Wikipedia.
"TSU made an interesting discovery for itself. It
turned out that Kim Yom Nam is in first place among our most popular graduates.
Who is he? Prominent politician of the Democratic People's Republic of Korea.
Mikhail Bashkatov is in second place, in third - Andrei Burkovsky," the
TSU scientist says.
Another study concerned a psychological portrait of a
benefactor who supports endowment funds of universities.
"Scientists have wondered what pushes people to
thank their universities and make contributions. Here, big data helped to
collect a digital trail of philanthropists on social networks, summarize it and
see some patterns. <...> All this helps universities improve methods of
working with graduates and increase the number of philanthropists," the
Personality and trail - all in the
" digital symbol"
The so-called digital model of a person or personality
is directly related to big data. As a rule, artificial intelligence is used to
compile such a model.
Feschenko notes: to understand what is meant by the
digital model of a person, you need to understand what a digital footprint is.
"There are activities in human life related to
learning and work. And in this part of digital space, a person generates a
digital footprint, but not very saturated. It can be used to predict what will
happen in human behavior, which requires a digital personality model. But from
the point of view of creating forecasts its digital footprint in social
networks, video hosting, instant messengers is richer," he says.
It is impossible to extract this data from everywhere
- scientists work with open user data in social networks, and this is a huge
layer of information. Science proves that from the digital trace you can
understand what a person is and what psychological features he has.
So, one of the studies showed that according to the
text on the "wall" of a particular person in social networks, it is
possible to determine which psychological type he belongs to. This experiment
was with the following scheme: real people performed a test, for example, at
the level of extraversion, then their digital footprint on Facebook was
investigated, and artificial intelligence found patterns.
It turns out that extroverts more often write texts
related to sports, recreation, beach, and introverts more often mention modern
What application can a digital footprint have?
"An example of TSU's "Robot Career Guide" - an application in
VKontakte, which will tell one of 10 professional areas in a few seconds that
suits you in interests and life values printed in a digital footprint. The
robot gives a forecast that will lead you to a list of professions, and there
you will be able to choose both the faculty and the university," Feschenko
Digital models of people are used in marketing,
political election campaigns and much more, the scientist notes. The scope of
application is growing every day - with the development of technology, and even
more so with the transition of the world to a deeper distant.
