Research work

The amazing technical progress of the past decades has opened a multitude of new possibilities to any of us. In our globalized world, spontanious and immediate digital communication plays a key role, in business as well as in private life. This is true even more, because relations, integrations and dependencies of different processes and workflows become more and more complex and time-critical.

My colleagues and I are researching for new algorithms and methods, better analysis-procedures as well as new models and simulation techniques, which allow innovative ways of information gathering and communication in real life. For this purpose, the chair of communication networks has invested in most modern hardware and has developed complex software tools. This equipment and the competence and experience of researching colleagues from all over the world makes the chair of communication networks ready for future challenges.

Decentralised Search Engines

Searching the Internet means today to use Google or any other big, centralised search engine. Besides wasting a huge amount of energy and other resources, those systems are neither trustworthy and scalable nor can they generate satisfying search results. After an analysis of the reasons for it, a new concept of a decentralised search engine is presented and some estimations on the complexity of search with it are given. The concept shall not be understood as the ultima ratio, but as a start of a discussion to find future search solutions.

Context-based and interactive seach for and with text documents

The search application DocAnalyser developed at the chair of communication networks is a new service that offers a novel way to interactively search for similar and related web documents and to track topics without the need to enter search queries manually. The user just needs to provide a web content to be analysed. This is usually the web page (or a specific part of it) currently viewed in the web browser. DocAnalyser then extracts its main topics and their sources (important inherent, influential aspects / basics) and uses them as search words. The returned search words and web search results are generally of high quality. This is mainly due to the implemented state-of-the-art graph-based extraction of keywords of the texts provided. Usually, the currently analysed web document is found again among the Top-10 search results which underlines and confirms this statement. Therefore, this tool can also be used to some extent to detect plagiarism in the WWW.

The service DocAnalyser is offered free of charge by the chair of communication networks.


Online feedback for eLearning

Multimedia and especially PowerPoint based video lectures become more and more a famous teaching opportunity for distance learning. While even the mobile Internet becomes fast enough to download the respective materials whenever and wherever needed, there is still no possibility for an ad-hoc feedback from the students to their teachers as known from standard lectures and seminars. Even feedback given by evaluations after the semester usually does not support comments to special slides or smaller sections of the course any more.

In the recent research project, this communication gap shall be eliminated. Students shall get by a respective software the possibility to use several gestures on their touchscreen to label unclear, wrong or bad explained parts of the slides while learning. Moreover, these information shall be collected in real time in an anonymous manner on the webserver of the provider, statistically evaluated and made accessible for the respective teaching staff to increase the quality of their online materials.
