These holiday days when partly has to spend time at work, but changes are not entered into the working systems any more because "soon holidays who needs your fresh bugs?", it is possible to be engaged in cutting asterisks and snowflakes from paper and small experiments.
Generally, we heard such expression more than once: "my call was kicked as a ball from the operator to the operator, and as a result bounced", and can even once it was told in a fit of temper. Also it was thought, and if to provide a call as the jumping ball from a wall to a wall and as at us several tens calls happen on an asterisk in one step, then it has to look at least funny.
2 years, 2 months ago It is analog paper "application", a volvell. That on a photo — the flight portable computer (rather modern volvella)
Each modern program thanks to thought over (we will optimistically see things) to the interface allows the person to obtain the necessary information quickly. To obtain data, it is necessary to move on the screen a finger-tip, and — voila, information already here. Perhaps, you will be surprised, but this idea did not appear presently. To it hundreds of years!
Of course, many tens, and even were not any screens, especially, touch hundreds years ago. But there were so-called volvella, it is quite possible to call them ancestors of modern applications. What is a volvella? Let's talk about it slightly below, and now – it is representable as defined time in old times without existence of a portable clockwork.
At the end of 2014 the MIEM new educational and administrative complex of Higher School of Economics National Research University in Strogin where many different abrupt things for training of students are implemented was put in operation. One of such projects — laboratory for prototyping of electronic and computing means. Under this business the small budget was selected, we are selected as the contractor. Further we solved not absolutely typical problem of creation of the room where around you fly different virtual 3D - objects. For example, that it was convenient to understand electronic chips.
It was necessary to apply creative imagination and just that mathematics which is vigorously mastered by students to achievement of effect of the return projection (when you pass it by the screen, but the shadow at the same time on it is not cast).
I like to open for myself new methods of thinking. Especially it is pleasant to observe how the vague idea is transformed to the specific concept. A striking example of it is the information theory.
The information theory gives us exact language for the description of many things. What degree of uncertainty? How to answer a question B, knowing the answer to a question A? Than one set of beliefs is similar to another?
When I was a child, I had some non-standard thoughts about it, but the information theory created them in specific, strong ideas which have a set of scopes of application: from data compression to quantum physics and machine learning.
The information theory looks frightening, but I think that it not so. Actually, many main ideas can be explained clearly.

While behind a window temperature on the way to the next records, it is interesting to look and what in general there were temperatures in any interval, for any years for the last several decades in 30 000 points worldwide. And can not lose with days of issue and take them those days when there is some "statistical benefit" in the selected location on warm weather, and can be on cold, having estimated it visually on any of three types of charts. Well or it is possible just to rotate the globe, to visually evaluate a variety of temperatures and "as this world is beautiful".
But if you thought that our "affair with Tolstoy" on it ended, then you were mistaken – having digitized texts of the writer, we began to investigate them by means of technology of information extraction ABBYY Compreno – not to vanish to such rich material. About what gave us "Thick text mining" and where now the received results are used, read further.
The main goal of the All Tolstoy in One Click project was to make Tolstoy's creativity rather general property that all texts which issued from its pen were available in one click in any point of Earth. As, by the way, the author who still during lifetime refused all rights to the texts also bequeathed (yes, the anonymous, Lev Tolstoy knew about a copyleft and an opendata long before this your Internet and Richard Stallman).
However an opportunity to load the book in a convenient format in the reader or the tablet – not the only plus of digitization. Now it is possible not only to read Tolstoy's texts, but also "to measure", that is to investigate by different quantitative methods, using all arsenal of means of hands-off processing of the text (AOT, it is NLP). If you have all texts of the writer in electronic form, even by means of one-two competent search queries you can obtain curious data for which production in other times some literary critic could spend weeks and months of persistent work. And if you besides have an advanced technology of the analysis of a natural language, that is chances to make serious philological discovery (even without being a philologist). Below I will tell that we managed to namerit and learn, but before it is the couple of words about the one who as well as why is engaged in hands-off processing of artistic texts and that interesting can turn out at the same time.
4 December days in a row, about 1300 people for 60 hours from 30 cities read "War and peace". The unprecedented multimedia project from VGTRK during which Lev Tolstoy's work was read from the first and to the last line. The project takes the grandness and pulls on the Guinness Book of Records.
In addition to a literary marathon a series of interactive infografichesky works under the auspices of analytical community Tolstoy Digital was released. Each infographics, and all them 4, analyzes work under razlichnyma corners: human relations, places, time, history, objects, culture in general.
Under a cat fragments from the novel, there is a little code and my thoughts on process of an infografirovaniye of data on the example of an event taymlayn.
Someone waits for Christmas, someone – a new series of Star wars, "Awakening of force". And at this time I decided to process all six-serial cycle from the quantitative point of view and to isolate the social networks which are contained in it – both from each movie separately, and from all Universe of ZV together. Fixed looking at social networks reveals interesting distinctions between original parts and their prequels.
Below – the social network got from all 6 movies in the sum.
In general, circles can tell a lot of things about school. A large number of sports sections, probably, speaks about existence of good halls and the equipment. The prices of circles, perhaps, speak about a kommertsializirovannost of school in general. Besides it was interesting to look whether the number of paid services influences success of school. Whether help to try to obtain a mug of the best rezult at examinations and the Olympic Games.
On pgu.mos.ru there is a section where it is possible to write the child in section. In night all this section was extorted and we on hands had information about 80 000 Moscow circles.
