Speaker: Andreas Hart, Institute AIFB at the Karlsruhe Institute of Technology
Talk Title: On-the-fly Integration of Static and Dynamic Linked Data
Abstract: The relevance of many types of data perishes or degrades
over time; to support timely decision-making, data integration systems
must provide access to live data and should make it easy to incorporate
new sources. We outline methods, based on web architecture that enable
(near) real-time access to data sources in a variety of formats and access
modalities. Our methods also enable rapid integration of new live sources
by modeling them with respect to a domain ontology, and by using these
models to generate a Linked Data interface to access them. Finally, we
present initial experimental results of a scenario involving several static
and dynamic sources from the web.
Biography: Dr. Andreas Harth is a post-doctoral researcher at Institute AIFB at the Karlsruhe Institute of Technology. His research interests are large-scale data interoperation on the Semantic Web, Linked Data, knowledge representation, computational logic and user interaction on web data. Andreas has published several dozen papers in these areas, and is author of a number of open source software systems. Recently, he has become interested in how to apply (RESTful) architectures and Read-Write Linked Data to cyber-physical systems (e.g., smart energy grids, surgery systems, mixed-reality systems).
Andreas was awarded his Ph.D. by the Digital Enterprise Research Institute (DERI) at the National University of Ireland, Galway. Andreas worked as intern at Fraunhofer Gesellschaft in Wuerzburg and at IBM's Silicon Valley Lab in San Jose, CA. His Diplom thesis was carried out in collaboration with Centro Politenico Superior at Universidad de Zaragoza, Spain. He visited USC's Information Sciences Institute in Marina del Rey, CA as a research assistant.
Andreas has participated in numerous EU and national projects. He served as program committee member of numerous conferences and is one of the co-organisers of the Consuming Linked Data (COLD) workshop series and of the Semantic Web Challenge.

Speaker: Qing Dou, USC/ISI
Talk Title: "Dependency Based Decipherment for Resource-Limited Machine Translation (EMNLP 2013 Practice Talk) "
Series: Natural Language Seminar
Abstract: We introduce dependency relations into deciphering foreign languages and show that dependency relations help improve the state-of-the-art deciphering accuracy by over 500%. We learn a translation lexicon from large amounts of genuinely non parallel data with decipherment to improve a phrase-based machine translation system trained with limited parallel data. In experiments, we observe BLEU gains of 1.2 to 1.8 across three different test sets.

Speaker: Kuzman Ganchev , (Google Research)
Series: Natural Language Seminar
Abstract: I will describe a framework for cross-lingual transfer of probabilistic models that uses posterior regularization. As a long aside, I will describe several methods for learning with side information: constraint driven learning, posterior regularization, generalized expectation, augmented loss as well as how they relate to each other and to Bayesian measurements. I will conclude with some applications from my work and from the literature, including sequence and tree models.
Biography: I was born in Sofia, Bulgaria where I lived until February 1989. My family moved to Zimbabwe and then in 1995 to New Zealand where I went to high school. I came to the US in 1999 to study at Swarthmore College. I spent the 2001-2002 academic year studying abroad in Paris. After graduating with a Bachelor of Arts in Computer Science in 2003 I worked at StreamSage Inc. in Washington DC until starting at the University of Pennsylvania in Fall 2004. During the summer of 2007 I was an intern at TrialPay in Mountain View, CA and during the summer of 2008 I was an intern at Bank of America in New York. I graduated from UPenn in 2010 and have since been working at Google Inc. in New York.

NL Seminar- Roy Schwartz :"Authorship Attribution of Micro-Messages"

Speaker: Roy Schwartz, NLP Lab, Hebrew University in Jerusalem
Talk Title: "Authorship Attribution of Micro-Messages"
Series: Natural Language Seminar
Abstract: Work on authorship attribution has traditionally focused on long texts. In this work, we tackle the question of whether the author of a very short text can be successfully identified. We use Twitter as an experimental testbed. We introduce the concept of an author's unique "signature", and show that such signatures are typical of many authors when writing very short texts. We also present a new authorship attribution feature ("flexible patterns") and demonstrate a significant improvement over our baselines. Our results show that the author of a single tweet can be identified with good accuracy.
