NL Seminar: Cultural Negotiating Agents
Fri, Jun 06, 2014 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Elnaz Nouri, USC/ICT
Talk Title: Cultural Negotiating Agents
Series: Natural Language Seminar
Abstract: People from different cultures and backgrounds tend to make different decisions faced with the same set of choices. Cultural background influences people's decisions in social interactions. Computational agents that are intended to simulate human behavior or engage in interpersonal interactions such as negotiation with humans need decision making models that are sensitive to culture. In this talk, we show how agents can learn to behave like people from specific cultures in the context of a negotiation game.
Biography: Elnaz Nouri is a PhD student in the Natural Language group at USC's Institute for creative Technologies (ICT).

NL Seminar-

Speaker: Julian Schamper, (RWTH Aachen)
Series: Natural Language Seminar
Abstract: Performing machine translation with monolingual data instead of parallel data is an interesting problem. Because of the lack of parallel data for many language pairs, solving the problem would arise interesting new use cases. On the road towards this we look at similar but easier problems. In the past improvements on simple substitution ciphers (1:1) were made - Even word substitutions ciphers with large vocabularies were solved for example by a beamsearch approach. This talk concentrates on the more complicated cipher class of homophonic substitution ciphers (1:m) like the famous Z408 of the Zodiac killer or the second page of the Beale cipher. We preset a method based on beamsearch. Covered aspects are an improved heuristic, the order the beamsearch should explore the search space, pruning, and the impact of the cipher lengths and cipher alphabet size on the deciphering accuracy.
Biography: Julian Schamper studies computer science at RWTH Aachen University. He did its bachelor thesis in the field of deciphering foreign language and works as a student research assistant at Prof. Hermann Ney's Human Language Technology and Pattern Recognition Group.

NL Seminar-"Scaling Semantic Parsing to Large Domains" [Intern talk]

Speaker: Eunsol Choi, University of Washington
Talk Title: Scaling Semantic Parsing to Large Domains [Intern talk]
Series: Natural Language Seminar
Abstract: We consider the challenge of learning semantic parsers that scale to large, open-domain problems, such as question answering or knowledge base completion with Freebase. In such settings, the sentences cover a wide variety of topics and include many phrases whose meaning is difficult to represent in a fixed target ontology. For example, even simple phrases such as `daughter' and `number of people living in' cannot be directly represented in Freebase, whose ontology instead encodes facts about gender, parenthood, and population. Here, we introduce a semantic parsing approach that learns to resolve such ontological mismatches. The parser uses a probabilistic CCG to build linguistically motivated logical-form meaning representations, and includes an ontology matching model that adapts the output logical forms for each target ontology.
Biography: Eunsol Choi is a Ph.D student at the University of Washington, advised by Prof. Luke Zettlemoyer. Prior to UW, she studied mathematics and computer science at Cornell University.
