Welcome to the website of the "Enterprise Platform and Integration Concepts" (EPIC) group.
Our activities are focused on the following research topics:
In-Memory Data Management for Enterprise Applications
Human-Centered Software Design and Engineering
In-Memory Data Management for Life Sciences
Our group includes PostDocs, PhD students, and student assistants, and is headed by Prof. Dr. Hasso Plattner. If you are interested in our work or want to join our team, please contact Dr. Matthias Uflacker.
Our team is giving a series of lectures and seminars with a focus on enterprise systems design and in-memory data management. Strong links to the industry ensure a close connection between theory and its implementation in the real world.
Our research focuses on the principles of in-memory data management on modern hardware and the integration of different hard- and software systems to meet business requirements. This involves studying the conceptual and technological aspects of modern enterprise applications as well as tools and methods for enterprise systems design.
We continually strive to translate our research into practical outputs that improve the quality of enterprise applications. A close link to industry partners ensures relevance and impact of our work. Get here an overview of our current and previous projects.
The current data deluge demands fast and real-time processing of large datasets to support various applications, also for textual data, such as scientific publications. Natural language processing (NLP) is the field of automatically processing textual documents. Processing and semantically annotating large textual collection is a time-consuming and tiresome task, which requires integration of various tools. In-memory database (IMDB) technology comes as an alternative given its ability to process large document collections quickly in real time.
We have a open position for students, please contact us!
Olelo is our NLP platform and integrate various NLP-related tasks for the biomedical domain.
NLP includes a variety of tasks such as tokenization (delimitation of words), part-of-speech tagging (assignment of syntactic categories to words), chunking (delimitation of phrases) and syntactic parsing (construction of syntactic tree for a sentence). Further, NLP also involves semantic-related tasks such as named-entity recognition (delimitation of predefined entity types, e.g., person and organization names), relation extraction (identification of pre-defined relations from text) and semantic role labeling (determining pre-defined semantic arguments). We have implemented many NLP methods in the SAP HANA database, as follow:
Chunking/shallow parsing and semantic role labeling (MP ss2015)
Named-entity recognition(BP 2015/2016)
Relation extraction (MP ws2015/2016)
There are many NLP applications that can be developed for various scenarios and domains, such as automatically generating summaries of one or more documents (summarization), retrieval of documents relevant for a particular query (information retrieval), extraction of specific information from a huge document collection (information extraction) and automatically answering questions posed by the users (question answering). We have developed NLP methods and applications for many of these task, as follow:
Deep learning to extract exact answers (Master thesis Georg Wiese)
Semantic role labeling to support question answering (Master thesis Fabian Eckert)

"A Course in In-Memory Data Management" by Prof. Dr. h.c. Hasso Plattner. This book is the culmination of six years work of in-memory research. As such, it provides the technical foundation for combined transactional and analytical workloads inside one single database as well as examples of new applications that are now possible given the availability of the new technology. The book is available at Springer.
