‘Systems of on-line kanji handwriting recognition’ seminar

The objective of the presentation was to describe modern systems of on-line kanji handwriting recognition. To this purpose, we presented some basic information about japanese language and writing system and we focused on the difficulties in identifying kanji characters.

The seminar was led by Małgorzata Gałężewska.

‘Recognition of the innovative logotypes on the web pages’ seminar

The objective of this presentation was to describe a found method for detection of logotypes that indicate innovativeness of companies, where the images originate from their Internet domains. To this purpose, we elaborated a system that covers a supervised and heuristic approach to construct a reference dataset for each logotype category that is utilized by the logistic regression classifiers to recognize a logotype category. The author in this presentation will show and explain in details the proposed approach.

The seminar was led by dr Marcin Mirończuk.

‘The requirements management and the changes management process in system analysis based on the project artifacts repository’ seminar

The objective of the presentation was to present the results of the research project in which we try to elaborate and develop the method of change management process of the project artifacts.

The main goals of the method are:

  • Unified version control functionality added to diagram repository application;
  • The possibility to show differences in time and between versions;
  • The possibility to show the relationship between the analytical and software artifacts;
  • To create to traceability matrix to show the relationship and the state and completeness between parts of the software project.

The seminar was led by Adam Bochenek.

‘A diversified classification committee for recognition of innovative Internet domains’ seminar

The objective of this presentation was to describe a classification method of innovative domains on the Internet. The proposed approach helped to estimate whether companies are innovative or not through analyzing their web pages. A Naïve Bayes classification committee was used as the classification system of the domains. The classifiers in the committee were based concurrently on Bernoulli and Multinomial feature distribution models, which were selected depending on the diversity of input data. Moreover, the information retrieval procedures were applied to find such documents in domains that most likely indicate innovativeness. The proposed methods have been verified experimentally. The results have shown that the diversified classification committee combined with the information retrieval approach in the preprocessing phase boosts the classification quality of domains that may represent innovative companies. This approach may be applied to other classification tasks. The seminar was led by dr Marcin Mirończuk.

European University Information Systems (EUNIS 2016) Congress

Marek Michajłowicz took part in the European University Information Systems congress in Thessaloniki, Greece. In this conference, it has been presented the article “A brief overview of the Information System for Science and Higher Education in Poland” that was created together with Jarosław Protasiewicz and Mikołaj Szypke. The objective of this paper was to introduce POL-on, Polish Information System for Science and Higher Education to the wider audience of European software providers for science and higher education. The conference was an opportunity to exchange experiences and ideas and to identify current trends in this area.

Part IV of ‘Introduction to frontend applications’ seminar

The last semiar on frontend programming took place on Thursday, April 7. The seminar covered Angular 2, the new web development framework from Google. We introduced Angular by comparing it to ReactJS since both frameworks share a lot of similarities. Afterward, we reviewed change detection mechanism, framework modules, existing libraries and tools for Angular 2. The seminar was led by Sławomir Dadas.

Part III of ‘Introduction to frontend applications’ seminar

The third seminar on frontend programming took place on Friday, April 1. Its goal was to familiarize participants with ReactJS framework. The seminar included brief introduction to component based view structure and how it was implemented in React. We also looked at change detection algorithm and popular event-driven Flux architecture. The seminar was led by Sławomir Dadas.

Part II of ‘Introduction to frontend applications’ seminar

The second seminar on frontend programming took place on Tuesday, March 22. The main topic of the meeting was to present libraries and tools used to organize and build JavaScript and TypeScript projects, with particular emphasis on modularity and how can project be structured to optimize application load time and performance. The seminar was led by Sławomir Dadas.
