Ongoing Projects

Educational Web 2.0 (EduWeb)

This project explores the use of Natural Language Processing (NLP) and collaboratively constructed resources on the web (i.e. Wikipedia and Wiktionary) for innovative applications in technology enhanced education.

Semantic Information Retrieval (SIR)

This project systematically investigates the possible usage of semantic and lexical relationships between words or concepts for improving the information retrieval process. The main focus is on semantic relatedness measures using different knowledge sources (e.g. WordNet, GermaNet, or Wikipedia).

THESEUS (Projects TEXO and MEDICO)

The project investigates the use of semantic technologies to enable future business value networks. Our main focus is the use of NLP and semantic IR technologies to enable automatic service search and discovery as well as community mining methods to recognize opinions and trends about services.

Semantics- and Emotion-Based Conversation Management in Customer Support (SIGMUND)

The project is concerned with an ultimately new area in the situation-aware support of phone-base customer support: optimizing the work of call center agents through an automatic call monitoring and a dynamic selection and presentation of the relevant documents during the call. Our contribution is in the area of semantic document analysis and context-aware information retrieval.

Mining Lexical-Semantic Knowledge from Dynamic and Linguistic Sources and Integration into Question Answering for Discourse-Based Knowledge Acquisition in eLearning

The project investigates novel applications of dynamic lexical-semantic resources for information search in eLearning. On the one hand, we develop novel ways of mining knowledge from Wikipedia and other Web 2.0 knowledge repositories. On the other hand, we apply question answering in the area of discourse-based knolwedge acquisition in eLearning for the first time.

Automatic Quality Assessment and Feedback in eLearning 2.0 (AQUA)

The project investigates the use of Natural Language Processing and Machine Learning techniques to automatically measure the quality of user generated textual documents in Web 2.0, such as forum posts, Wikipedia articles, or blog entries. This can be utilized to recommend the user (e.g. the learner) high-quality materials, to implement quality-aware information retrieval, or to predict the popularity of web sites for computational advertising.

Wikulu - Self-Organizing Wikis

Wikulu assists the user while creating, editing, or searching content. The self-organizing abilities of the wiki are enabled through Natural Language Processing algorithms like keyphrase extraction, document summarization, document clustering, or graph-based term weighting.

Darmstadt Knowledge Processing (DKPro) Repository

The DKPro Repository consists of a growing number of scalable, robust and flexible UIMA components for various kinds of NLP tasks such as tokenization, sentence splitting, PoS tagging, negation detection, lexical chaining, word pair extraction.

Sentiment Analysis for User Generated Discourse in eLearning 2.0

The project aims to support easy exploration of subjective content and feedback generation to content providers. We develop components for subjectivity identification, opinion and topic extraction.

Ambient Semantic Computing (ASC)

Video lectures, audio recordings, wiki content, and forum entries are often seen as separate entities. The goal of ASC is the integration of these multimodal content streams by combining techniques from Natural Language Processing and Human Computer Interfaces.
