Master Thesis: Extracting a Repository of Events and Event References from News Clusters
Silvia Julinda created an approach for mining events and their textual representations from news clusters on the Web. Her thesis work led to a publication at the AHA! Workshop on Information Discovery at COLING 2014.
Priska Herger used clustering methods on large corpora of text to determine broad relationship types that hold between nouns, such as hypernymy, meronymy, co-hypernymy and others.
Diplomarbeit: Automatisierte Extraktion textueller Änderungen aus dem Bearbeitungsverlauf von Online-Nachrichtenartikeln
("Extracting Microedits from Online News Articles")
Christian Niedrich mined online news for 'microedits', i.e. small changes that are made to online news articles after they are online. He is developing a method that automatically constructs a corpus of such edits.
Bachelor Thesis: A Workflow for Defining Information Extraction Patterns Oresti Konomi designed a workflow and implemented a tool for defining Information Extraction patterns addressed at users without a background in NLP. Together with the work from Michail Melnikov's bachelor thesis, this work has been published as an ACL 2013 demo.
Bachelor Thesis: Design und Umsetzung eines Systems zur verteilten Ausfuhrung von patternbasierter Informationsextraktion
("Design and Implementation of a System for Distributed Pattern-Based Information Extraction")
Michail Melnikov built a system that executes complex Information Extraction patterns in a distributed environment. Together with the work from Oresti Konomi's bachelor thesis, this work has been published as an ACL 2013 demo.
Diplomarbeit: Automatisierte Extraktion von Zitaten und zugehörigen Themen aus Webdokumenten
("Automatic Extraction of Quotes and Speakers from Web Documents")
Philipp Keese built and evaluated an Information Extraction system that finds quotes and their speakers in Web documents.
Bachelor Thesis: Mining von Events in Twitter mit Fokus auf deutscher Politik
("Mining Twitter Events with Focus on German Politics")
Kfir Admoni built a system that continuously mines twitter for news related to German politics for 'hot topics'.
Bachelor Thesis: Gezieltes Retrieval von faktenstarken Sätzen im Web auf Basis von Wikipedia
("Targeted Retrieval of Sentences with High Information Content from the Web")
Do Tuan Ahn built a system that finds and retrieves sentences that contain factual data from the Web.
Stephan Pieper investigated machine learning approaches to automatically learn patterns for N-ary open information extraction.
Bachelor Thesis: Information Extraction von Zitaten in türkischsprachigen Quellen
("Quote-Extraction from Turkish Newswire Text")
Ahmet Karakas built a pipeline for extracting quotes and speakers from Turkish-language text. He will also conduct a survey of existing NLP resources for the Turkish language. The results of his work will be integrated into the QuoteMine project.
Bachelor Thesis: Extraktion von Relationen und Konzepten von komplexen Nominalphrasen
("Extraction of Relations and Concepts from Complex Noun Phrases")
Umar Maqsut extracted information from complex noun phrases and investigated when such phrases can be used as concepts in a knowledge base.
Bachelor Thesis: Implementierung und Evaluierung eines Verfahrens zur Erhöhung der Qualität der flachen Extraktion komplexer Nominalphrasen
("Using World Knowledge to find Complex Noun Phrases in Shallow Parsing")
Stefan Schramm investigated a number of 'world knowledge' features in a CRF classifier for finding complex noun phrases, something that can normally only be achieved using a deep syntactic parser. He trained a classifierusing different featuresets and evaluates the results.
This is my Master thesis, which I submitted in May 2009. I examine Relation Extraction as a method for
automatically generating a semantically annotated wiki from the English Wikipedia. This work has given
rise to many ideas I have since been exploring.
