Prof. Herwig Unger

Title: Brain Inspired methods for Natural Language Processing


Prof. Dr.-Ing. habil. Dr. h.c. Herwig Unger (1966) received his PhD with a work on  Petri Net transformation in 1994 from the Technical University of  Ilmenau and his doctorate (habilitation) with a work on a fully decentralised web operating systems from the University of Rostock in 2000. Since 2006, he is a full professor at the FernUniversität in Hagen and the head of the Department of Communication Networks. In 2019, he obtained a honorary PhD in Information Technology from the King Mongkut’s University of Technology in North Bangkok (Thailand). His research interests are in decentralised systems and self-organization, natural  language processing, Big Data as well as large scale  simulations. He has  published more than 150 publications in refereed  journals and conferences, published or edited more than 30 books and gave over 35 invited talks and lectures in 12 countries. Beside various industrial co-operations, e.g. with Airbus Industries, he has been a guest researcher/professor at the ICSI Berkeley (USA), the University of Leipzig and other universities in Canada, Mexico and Thailand.


Until today, the human brain ist still the most advanced and powerful information processing and communication unit on earth; the highly parallel working millions of neurons with their complex connectivity allow complex operations like abstraction,  the building of hierarchies, as well as an invariant, associative storage of a huge amount of information.
The basic design of some of those processes may inspire new methods for natural language processing and information retrieval, It is intended to introduce in the keynote TheBrain project of researchers at FernUniversität in Hagen (Germany)  as well as KMUTNB (Thailand) applying such innovative  methods in the context of a huge, decentralised (P2P) system to support natural language processing.
It will be shown, how the computing intense construction of frequently used co-occurrence graphs can be parallelised in a new manner and how new routing and fault tolerance algorithms can be implemented. Last but not least, methods to model oblivion, abstract categories as well as  frequent sequence learning will be introduced and first simulation results are presented.

Data contain hidden knowledge applied for decision-making in a wide variety of applications such as businesses/manufacturing selections and other decision-making tasks in governmental sections. Data mining techniques has been implemented to extract knowledge from small raw datasets; however, the knowledge results from small data may not be enough for a given task, as it does not cover the universe of domain of interests. This may be due to an under-fitting problem that is too few samples in the domain of interests. So big data should be applied if they are available. As big data are now more and more exponentially increase due to the rapid growth of the Internet of Things, manufacturing data, machine-generated data, and social network user-generated data. Nevertheless, mining big data is not easy; it is required suitable knowledge about big data analytics. This keynote talk is about the big data analytics problems and challenges including big data ecosystems and technologies, big data mining techniques, and machine learning in big data problems. The talk will give brief reviews state-of-the-art of deep learning for big data including Convolutional Neural Network (CNN), Recurrent Neural Network (RNN), Long Short-Term Neural Network (LSTM), and Gated Recurrent Unit (GRU). Applications of deep learning and big data on Image Processing and Natural Language Processing will be also covered.

Waralak Vongdoiwang Siricharoen is Assistant Professor of Faculty of Information and Communication Technology, Silpakorn University, Bangkok, Thailand. She received her master degree in Business Administration with Computer Information Systems Certificate in 1999 from University of Southern New Hampshire (New Hampshire College), NH, USAAnd she received her Doctoral Degree of Technical Science in 2005 from Asian Institute of Technology (AIT), ThailandHer previous works focus on creating the object models from ontologiesHer works have been reported in peerreviewed papers published in international journals, conference proceedings, and booksHer research area specialists are ontologies, database technology, software engineering, object oriented, human computer interaction, etc


Exploring user attitudes and behaviors within the domain of interests helps the user experience team to match the user with a deeper understanding. The mapping process also reveals any gap in existing user data. Design thinking is the ground-breaking and cooperative approach to problem-solving that puts the user first to make user-centered products and services. There are many various design thinking activities that use to generate a thoughtful of the users or customer, including the conception of personas. This paper revisits the concept of persona and draws the connection of using empathy map to build persona within the design thinking process. Also showing the benefit of empathizing method to construct the effective persona.This can be used for the benefit in Human Computer Interaction(HCI) designing processes or marketing analysis.
