Past Projects

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.

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.

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

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.

Semantic Assistance Services for Career Integration and Personal Competence Development

The SABINE project (German: "Semantische Assistenzdienste für die berufliche Integration und Persönliche Kompetenzentwicklung") develops methods to interlink the databases of recruitment agencies, personnel services and human resources departments by means of semantic methods. The UKP Lab's contribution will be in methods which extract semantic knowledge from domain-independent sources like Wikipedia by means of statistical text analysis.

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.

Secure Documents using Individual Markers (SiDiM)

The primary goal of the project is to develop novel methods that individualize electronic documents through the manipulation of their textual content that is unrecognizable by a reader. The marks are supposed to be difficult to remove, and at the same time to have no recognizable affect to the meaning of the content. This solution will be embedded in an electronic document distribution environment and remain transparent to an end user.

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.

Semantic Information Retrieval Part 1 & 2 (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. WordNetGermaNet, or Wikipedia).

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.
