Turing Talk

Fabian Suchanek (Max-Planck-Institute for Computer Science)
YAGO - A Core of Semantic Knowledge
January 29 (Thursday), 11:00 am - 12:30 pm, Paul G. Allen Center for Computer Science and Engineering 305

The slides of this Turing Talk are available.

Abstract

This talk will present YAGO. YAGO is a large ontology, which currently contains more than 2 million entities and close to 20 million facts about them. The talk will explain how YAGO was constructed and how we represent YAGO's knowledge. It will also introduce the SOFIE project. SOFIE uses logical reasoning to extract new information for YAGO from Web sources.

Speaker

Fabian Suchanek recently received his PhD in Computer Science at Max-Planck-Institute; he was advised by Professor Gerhard Weikum. Fabian has been working in the areas of Automated Reasoning, Information Extraction, Ontologies and the Semantic Web. His main work is the YAGO ontology.

Turing Talk

Francis Bond (MASTAR Project, National Institute of Information and Communications Technology)
Opportunistic Lexicon Development
February 18 (Wednesday), 11:00 am - 12:00 noon, Paul G. Allen Center for Computer Science and Engineering 403

Abstract

In this talk I present a variety of opportunistic methods for rapidly building bilingual lexicons. They include: linking through multiple languages, deducing semantics from numeral classifiers, identifying cognates using Chinese characters and finding translations in mainly monolingual corpora.

Symposium

Eighteenth UW/Microsoft Quarterly Symposium in Computational Linguistics
April 10 (Friday), 3:30 pm - 5:30 pm, Mary Gates 241

You are invited to take advantage of this opportunity to connect with the computational linguistics community at Microsoft and the University of Washington. Sponsored by the UW Departments of Linguistics, Electrical Engineering, and Computer Science; Microsoft Research; and UW alumni at Microsoft.

Talk 1

Vikram Dendi (Microsoft Research)
Standing in the User’s Shoes—Enhancing the “Perceived Value” of Translation

Abstract

Microsoft recently announced a technology (Translator Widget) that makes it dead simple to bring machine translations to a web page. Why does MSR’s machine translation team see this as a critical step in increasing the value of MT? In his responsibility of planning the innovation value chain for this team at Microsoft Research, Vikram has been exploring the idea of “perceived value” and how it ties into translation quality. The “perceived value” concept contrasts with more empirical methods of measuring (translation) quality in that it captures a user’s overall expectation of the value that a technology delivers to them. You will have an opportunity to contrast the scientist’s viewpoint with that of a strategist in this brief conversation.

Speaker

Vikram Dendi wears multiple hats in Microsoft Research’s machine translation team. He primarily leads business strategy and planning for the team, but also spends a lot of time thinking about the user experience.

Talk 2

Kevin Duh (Signal, Speech, and Language Interpretation Lab, UW)
Semi-Supervised Learning for Ranking

Abstract

The problem of ranking, whose goal is to predict an ordering over a set of objects, is a key problem in many applications. In web search, for instance, ranking algorithms are used to order webpages in terms of relevance to the user. In complex NLP systems (e.g. machine translation, parsing), a set of candidate hypotheses is re-ranked such that the best one emerges at the top. While ranking has become an active research area, most work is done under the framework of supervised learning.

In this talk, I will discuss whether ranking algorithms can be extended to the semi-supervised learning framework, i.e., “Can additional unlabeled data be exploited to improve ranking performance?” I will begin by surveying possible approaches in this open area (based on prior work in semi-supervised classification). Then I will introduce a general “transductive/local” meta-algorithm for turning a standard supervised algorithm into a semi-supervised one. Results in the context of information retrieval will be presented.

Speaker

Kevin Duh is a PhD student at the University of Washington. He is a member of the UW SSLI lab, where he works on in natural language processing, information retrieval, and machine learning. In particular, he is interested in minimally-supervised approaches for resource-poor languages and complex structured problems. He received his B.S. in Electrical Engineering from Rice University in 2003 was an NSF Graduate Fellow from 2005-2008.
