Shahrukh Badar defended his Master Thesis on Process Mining for Workflow-Driven Assistance in Visual Trend Analytics

/in , , , /by

In his thesis, Shahrukh Badar created process-driven assistance that is applied to the visual trend analytics domain. The goal was, based on previous users interactions and solved tasks, to assist further users in their work. Therefore, a universal visual assistance model was defined and acts also as the main contribution, based on defined interaction event taxonomy. This concept was applied to the Visual Trend Analytics domain on the SciTics reference system. This “SciTics – Science Analytics” is connected with different data sources and provides analysis of scientific documents. The interaction model provides assistance in terms of recommendations, where the user has an option either to apply a recommendation or ignore it. The solution provided in this thesis is model-based and utilizes the potential of Process Mining and Discovery techniques. It is started by creating an event taxonomy by identifying all possible ways of user interactions on the “SciTic – Visual Trend Analytics” web application. Next, enable the “SciTic – Visual Trend Analytics” web application to start logging events chronologically based on predefined taxonomy. Later, these events log is converted into Process Mining log format. Next, it applies the Process Discovery algorithm “Heuristics Miner” on these log data to generate a process model, which shows the overall flow of user interaction along with the frequencies. Later, this process model is used to provide users with recommendations.

Sibgha Nazir defended her Master Thesis on Visual Analytics on Enterprise Reports for Investment and Strategical Analysis

/in , , , /by

In her thesis, Sibgha Nazir created a visual analytical approach to analyze annual financial reports in the perspective of investors’ interests. The goal of the thesis is to make use of visual analytics for the fundamental analysis of a business to support investors and business decision-makers. The idea is to collect the financial reports, extract the data and feed them to the visual analytics system. Financial reports are PDF documents published by public companies annually and quarterly which are readily available on companies’ websites containing the values of all financial indicators which fully and vividly paint the picture of a companies’ business. The financial indicators in those reports make the basis of fundamental analysis. The thesis focuses on those manually collected reports from the companies’ websites and conceptualizes and implements a pipeline that gathers text and facts from the reports, processes them, and feeds them to a visual analytics dashboard. Furthermore, the thesis uses state-of-the-art visualization tools and techniques to implement a visual analytics dashboard as the proof of concept and extends the visualization interface with interaction capability by giving them options to choose the parameter of their choice allowing the analyst to filter and view the available data. The dashboard fully integrates with the data transformation pipeline to consume the data that has been collected, structured, and processed and aims to display the financial indicators as well as allow the user to display them graphically. It also implements a user interface for manual data correction ensuring continuous data cleansing.

The presented application makes use of state-of-the-art financial analytics and information visualization techniques to enable visual trend analysis. The application is a great tool for investors and business analysts for gaining insights into the business and analyzing historical trends of its earnings and expenses and several other use-cases where financial reports of the business are a primary source of valuable information.

Establishment of an Afghanistan Online University

/in , , , , , /by

The Human-Computer Interaction and Visual Analytics group of the Darmstadt University of Applied Sciences led the technical sessions on the first conference on establishing the Afghanistan Online University. Prof. Dr. Kawa Nazemi was assigned to the steering committee and the coordination team of the envisaged university.

The Afghanistan Online University aims to provide young persons of Afghan origin living outside Afghanistan – notably those living in refugee camps and other precarious settings – the opportunity to acquire general professional competencies and expertise in Afghan culture and society. A comprehensive system of online teaching, learning, and examination concurrently ensure the accessibility of the study provisions for young persons living in Afghanistan.

Students will be prepared to be professionally active in tune with their competencies all over the world and contribute to a desirable future of Afghanistan. A mix of professors and junior academics both from various countries of the world and of Afghan origin – among them those having lost the opportunity to serve universities in Afghanistan – can contribute to academic quality in all disciplines represented and the enhancement of knowledge on Afghan culture and society. Cooperation in teaching and research will be encouraged between scholars employed at this online university, those at a partner institution to be found for each discipline, and persons from many countries and institutions to be involved on a part-time basis.

Study programs on bachelor and master level, similar in length to the dominant „Bologna“ practices, as well as doctoral training will be provided – as customary at most open universities in the world – in the humanities, social sciences, and economic sciences, actually in 10 fields: Language and literature, education, psychology, social work, sociology, political science, journalism/communication science, economics, business studies, and additionally in IT/computer science. Master programs might specialize in certain topics (e.g. natural resources management) or interdisciplinary (e.g., gender studies). These fields are likely to be enriched by a creative dialogue between the theories, methods, and findings and the specifics of culture and society of Afghan culture and society. No study programs are envisaged in fields requiring substantial laboratory work or internships, of a clear universalistic knowledge base, and a sole national or regional thrust. Further education and continuing professional education programs might be added in the future.

Altogether, 60 professors and the same number of junior academic staff (FTE), supported by a substantial number of administrative staff, have to be employed for the ten disciplines to cover half of the teaching assignments and to be the backbone of research. A quarter of teaching each will be taken care of by scholars of the partner institutions and scholars from all over the world being involved part-time. Altogether, about 5,000 students can be accommodated, and a further increase can be realized with limited additional resources.

The online university will strive for high academic quality, a convincing link between academic quality and professional relevance, a guarantee of academic freedom, as well as support of the academic areas and of those persons suffering most under current adverse political conditions in Afghanistan, i.e., ethnic and religious minorities as well as women.

Irtaza Rasheed defended his Master Thesis on Name Disambiguation on Digital Library Data for an Enhanced Profile Analysis in Visual Trend Analytics

/in , , , /by

In his thesis, Irtaza Rasheed implementated a universal name disambiguation approach that considers almost any existing property to identify authors. After an author of a paper is identied, the normalized name writing form on the paper is used to refine the author model and even give an overview about the different writing forms of the author’s name. This can be achieved by first examine the research on Human-Computer Interaction specifically with focus on (Visual) Trend Analysis. Furthermore, a research on different name disambiguation techniques. After that, building a concept and implementing a generalized method to identify author name and affiliation disambiguation while evaluating different properties.
