[Foursquare Spatial Desktop](https://foursquare.com/products/spatial-desktop) - a powerful geospatial analysis tool and modernized version of [Kepler.gl](https://kepler.gl) running natively on your desktop with an embedded [DuckDB](https://duckdb.org/) as the spatial processing engine.

The big win? Everything happens locally. Your data stays on your machine – you're not limited by network bandwidth or shared cloud resources, you can fully utilize your desktop computer and can save projects as local files.

And... The app is built on [SQLRooms](/p/sqlrooms) - our open-source framework for creating data analysis environments.

[FlowmapBlue](https://flowmap.blue)
is a free tool for representing aggregated numbers of movements between geographic
locations as flow maps. It is used to visualize urban mobility, commuting behavior,
bus, subway and air travels, bicycle sharing, human and bird migration, refugee flows,
marine traffic, freight transportation, trade, supply chains, scientific collaborations,
epidemiological and historical data and data on many other topics.

The project [won bronze](https://twitter.com/kachkaev/status/1197262339935997952)
at the [Information is Beautiful Awards](https://www.informationisbeautifulawards.com/showcase/3815-flowmap-blue)
in 2019.

<embed src="flowmapblue-palermo-anim-4mapbox.mp4">

Until recently making flow maps has involved manual drawing, knowledge of programming or
specialised software.
I had learned from my experience developing
[flow](https://github.com/ilyabo/jflowmap)
[mapping](https://github.com/ilyabo/jflowmap.js)
[libraries](https://github.com/teralytics/flowmap.gl)
that there was a need for an _easy-to-use_ tool with which people without special
knowledge could make flow maps.
This is why I decided to develop flowmap.blue.
The tool makes it possible to publish interactive flow maps from data uploaded to Google Sheets.
It's free, it requires no installation and allows anyone to create a flow map in no time.

Data visualization made for [Resource Matters](https://www.resourcematters.org/) showing where the cobalt produced by certain companies ends up, to identify potential levers and pressure points, in hope that this helps improve corporate behavior on the ground.

Testimonial from <a href="https://resourcematters.org">Resource Matters</a>:

<blockquote>
We collaborated with Ilya on the development of a platform visualizing transactions along the supply chains of several cobalt-containing products. We were very satisfied with the results. After a quick introductory call, Ilya presented a mockup that ended up being pretty much the final version, while also resolving a major issue we initially had with our data. Further work involved expanding our initial data display ambitions. The back and forth was always speedy. By asking the right questions, Ilya easily understood (and helped us understand, which is more complex as we are not visualization experts) what we wanted to communicate and how to make it clearer and more user-friendly. The final product achieves a balance between being lightweight, beautiful, and self-explanatory, surpassing our expectations. We intend to continue collaborating with Ilya for future iterations of this platform and other projects. We highly recommend other companies to consider his services."

Network analysis tools can be intimidating, and especially, the data preparation in the form that these tools expect (which often involves combining multiple datasets) can be very time-consuming. SQL is a very powerful and quite popuar language for data analysis and manipulation which can be of immense help for the data preparation. However, setting up a database with an SQL query engine is often a tedious process. Thanks to [DuckDB](https://duckdb.org/) we can now run an efficient SQL database, execute queries directly in the browser and pass the results to a graph layout engine to visualize them as a network.

I built a simple video annotation tool used for a medical study
carried out at [Charité – Universitätsmedizin Berlin](https://nephrologie-intensivmedizin.charite.de/).

The full title: [“Point-of-care lung ultrasound in COVID-19 patients: inter- and intra-observer agreement in a prospective observational study”](https://www.nature.com/articles/s41598-021-90153-2).
The results of the study were published in [Nature - Scientific Reports](https://www.nature.com/articles/s41598-021-90153-2).

Testimonial from <a href="https://www.linkedin.com/in/frederic-muench-md-72b56042/">Frederic Muench, MD,
Resident Physician, Nephrology & Intensive Care at Charité</a>:

<blockquote>
We collaborated with Ilya in a COVID-19 intensive care unit project at the university hospital Charité Berlin and were thrilled by his work. Within a week after kick-off we had a working and stable online tool which incorporated more functionalities than expected and its usability and design (which was crucial to the project) was just great! Ilya had additionally optimised our initial idea which in the end resulted in a much more broadly usable tool. He also agreed to modify the tool for a follow-up study. The results of the projects are currently in review and will be published for the medical community soon. This would not have been possible without Ilya's commitment and effectiveness. We definitely endorse Ilya and his work, and really hope to further collaborate!

  The presidential election in 2012 in Russia was clearly fradulent.
  Despite manipulating the results the authorities published very detailed data on the elections
  which made it possible to analyse it and find traces of fraud.

![Vote for Putin in 2012 presidential elections in Russia.](2012-orangevaya-zaraza3-crop.png)

The dark blue dots show polling stations which reported unlikely high votes for Putin:
![](orangevaya-zaraza-large-3.png)


The above visualization was used by the Danish online magazine Europa in [this article](http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fmagasineteuropa.dk%2F%3Fp%3D5544&act=url) (translated from Danish).



## Vote for Putin vs Turnout

Each dot is a polling station, x-axis is the turnout, y-axis is vote for Putin. Here you can see that there is a very high correlation between the turnout (the percentage of people who voted) and the vote for Putin. This correlation is most probably due to the fact that in the polling stations where the turnout was reported as unlikely high votes for Putin were injected.
Anoter anomaly is “the grid pattern”, that is, the higher concentration of reported turnout and vote for Putin around 75, 80, 85, 90, 95%. This is a clear evidence of fraud.

In this research study we analyzed ﬁndings made by the participants with ﬂow maps using animation and small-multiples as two alternative ways of representing temporal
changes. 

![](interaction-timeline.png)

The goal was to ﬁnd out whether there are qualitative differences between the types of ﬁndings users make with these two representations. 
This required a deep analysis of the collected ﬁndings and the interaction logs. To enable this analysis
I developed web based tools for collaborative  classification of the findings, resolving disagreements in the classification and a visualization of the interaction logs.

User study on visualizing temporal changes in flow maps

Flow map user study


Flowstrates extend the idea of a [flow map](http://en.wikipedia.org/wiki/Flow_map) (which are used for representing entities flowing between geographic locations) to the temporal dimension and allow to analyze the changes of the flow magnitudes over time. In Flowstrates the origins and the destinations of the flows are displayed in two separate maps, and the temporal changes of the flow magnitudes are displayed between the two maps in a heatmap in which the columns represent time periods.

![](Flowstrates-2012.png)

<iframe width="560" height="315" src="https://www.youtube.com/embed/nij8OUyiaV0?rel=0&amp;controls=0&amp;showinfo=0" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>

As in most flow maps which focus on representing the flow magnitudes, the exact routes of the flows are not accurately represented in Flowstrates. Instead, the flow lines are rerouted so that they connect the flow origins and destinations with the corresponding rows of the heatmap, as if the flows were going through it. The flow lines help to see in the geographic maps the origins and the destinations corresponding to each of the flows shown in the heatmap.

<iframe width="560" height="315" src="https://www.youtube.com/embed/UQPN7o6A3Cg?rel=0&amp;showinfo=0" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>

Flowstrates are meant for interactive exploration. Unlike OD-matrices which represent exactly one flow in each matrix cell, in Flowstrates every flow occupies one whole row of the heatmap for showing how the flow changed over time. Hence, much more screen real estate is used to represent the same number of flows, and for many datasets it is impossible to display all the flows simultaneously on the screen without filtering or aggregating them. Therefore, to allow the users to explore the whole data in every bit of detail Flowstrates provide interactive support for performing spatial visual queries, focusing on different regions of interest for the origins and destinations, zooming and panning, sorting and aggregating the heatmap rows.

You can also read our [paper on Flowstrates](/assets/flowstrates-eurovis11-fin.pdf) published in Computer Graphics Forum.

Flowstrates is a part of JFlowMap, an open-source tool for the analysis of spatial interactions.

A visualization tool in which we experiment with various visualization techniques for spatial interactions, i.e. interactions between pairs of geographic locations. These can be migrations, movement of goods and people, network traffic, or any kind of entities "flowing" between locations. Spatial interactions are often represented as origin-destination data, meaning that only the origins, the destinations and the magnitudes of the flows are known, but not the exact flow routes.

<img src=simqa.png alt="Components of a Question Answering System">

This system, developed for my master's thesis,
learned how to transform queries for [question answering](https://en.wikipedia.org/wiki/Question_answering)
in the Web. The goal of such transformations is to construct a query for a
traditional Web search engine given a factual natural language question so that
the first several documents returned by the search engine by this query contain
the correct answer to the original question. In other words, the system enhances web-based question answering by transforming natural language questions into effective search engine queries. It uses statistical algorithms, particularly the QASM model, to learn the best ways to modify a question for optimal search results. The system addresses the challenge of fact-based question answering on the web, where the quality of query transformation is crucial.
Key aspects and features of the system include:

- Query transformation modifies questions by adding, deleting, or replacing words, or by adding search engine syntax operators. Transformations are categorized into "translation" transformations that express the query in a different way and "refinement" transformations that modify the semantics of the query.
- The system employs atomic operators, such as stemming and stop word removal, to make transformations.
- A training process uses a set of questions and answers to learn the best sequences of atomic transformations. The system uses an Expectation Maximization (EM) algorithm to iteratively improve the model. The QASM algorithm is trained to map query contexts to the best atomic transformation operators.
- A modified QASM algorithm (modQASM) generates multiple query variations and uses a scoring function to select the most relevant ones. This modification addresses the issue that different transformations may be optimal for very similar questions.
- The system is evaluated using Mean Reciprocal Rank (MRR) and Total Reciprocal Document Rank (TRDR) metrics. These metrics measure the effectiveness of the query transformations by considering the rank of correct answers in search results. TRDR is more sensitive to differences in query effectiveness as it considers all correct answers within the top results, whereas MRR only considers the first correct answer.
- A prototype system was developed using the Yandex search engine and its specific syntax. It includes specific operators for the Yandex search engine, such as one that disables morphological analysis.
- The system uses the TRDR metric for both training and evaluation purposes.
- In modQASM, each generated query is given a significance score, which can be based on the probability of its selection or the selectivity of the atomic operators used to create it.
- Experimental results showed that the modified QASM algorithm outperformed the original QASM and direct Yandex search. The experiments also showed that the removal of words operator and the number of proper nouns in a query were the most significant for the overall effectiveness of the system.
  The system aims to improve the accuracy of web searches for fact-based questions by intelligently transforming them into queries that produce the most relevant results. The research also explores the limitations of current query transformation methods and how to address them.
