Proceedings of the Annual Conference of JSAI   2018(0) 4Pin129-4Pin129   2018
<p>We are developing a conversation system which efficiently transfers a massive amount of information like news articles by spoken dialogue. Here, "efficient" means that only the necessary information is transferred except unnecessary information...

Proceedings of the Annual Conference of JSAI   2018(0) 3Pin123-3Pin123   2018
<p>In a human-human conversation, a listener frequently conveys various intentions explicitly/implicitly to the speaker with reflexive short responses. The speaker recognizes the intentions of these feedbacks and changes the utterance plans to mak...

<p>This paper describes a spoken dialogue system for accommodating a user's information behaviors with various levels of information need. Our system, given a set of same-topic news articles, compiles a utterance plan that consists of a primary pl...

Research Grants & Projects

Deep semantic annotation of video contents
Project Year: Apr 2017 - Mar 2021
Towards integrated use of different lexical knowledges
Project Year: Apr 2015 - Mar 2018
These are three major frameworks to represent lexical knowledge, knowledge on word senses. In this study, we examined relationships among those and investigated their integrated use. On the representation based on semantic subsumption (hpyonymy) r...
Semantic similarity using human associative knowledge
Project Year: Apr 2014 - Mar 2017
Developing an appropriate computational mechanism of semantic similarity between linguistic expressions is an important subject for both engineering applications and cognitive science. In this research project, by focusing on evocation relationshi...
Building Multilingual Lexical-Semantic Web by Sense Linking
Project Year: Apr 2013 - Mar 2017
We studied a methodology for linking lexical-semantic resources with different conceptual systems in different languages on the basis of Linked Data. The key element of the proposal is “linking by meaning”: the probabilistic correspondences of con...
Exploring the grouning of linguistic concepts in images on the Web
Project Year: Apr 2012 - Mar 2014
The recent research direction toward multimodal semantic representation would be further advanced, if we could have a machinery to collect adequate images from the Web, given a target concept. With this motivation, this research particularly inves...
