Title: Knowledge Representation in the Era of Deep Learning, Watson and the Semantic Web
A burst in optimism (and unwarranted fear) has grown around a number of technologies that are high impact and able to solve problems that have challenged AI researchers for years. The over-enthusiasm that often follows such breakthroughs has caused some to declare (yet again) that it is the end of "knowledge representation" as AI moves into a world dominated by neural networks, data mining and the knowledge graph. In this talk, I argue that these technologies, while extremely powerful separately, are not only still a long way from human intelligence, but cannot get there without a level of knowledge and reasoning beyond what is currently available to these techniques, On the other hand, I also argue that taking these technologies into new and harder realms will require rethinking what knowledge representation is and how it is used.

He is also the first computer scientist to serve on the Board of Reviewing editors for Science. In 2010, Hendler was selected as an "Internet Web Expert" by the US government. In 2012, he was one of the inaugural recipients of the Strata Conference "Big Data" awards for his work on large-scale open government data, and he is a columnist and associate editor of the Big Data journal. In 2013, he was appointed as the Open Data Advisor to New York State and in 2015 appointed a member of the US Homeland Security Science and Technology Advisory Committee and in 2016, became a member of the National Academies Board on Research Data and Information.

Research Session (30 min / each talk)

Hideaki Takeda (NII)

Title: Design Process of Agriculture Ontologies
In this talk, I will talk about the experience of designing and developing the agriculture ontologies, in particular, how the structure of the ontologies were defined as the agreement. We are currently developing two ontologies: the ontology for agriculture activity (AAO) and the ontology for crop. Since they are domain ontologies, there needs the collaboration between computer scientists and domain experts. We learnt the importance of iterative interaction between two sides. Furthermore we have two parties in domain experts. One is the member of the developing team who know computer science and agriculture both and the other is the experts who only know agriculture. The former is important to bridge the gap between knowledge about computer science and agriculture.

Hiroshi Masuya (RIKEN BioResource Center)
Title: RDF based integration of biological phenotype data produced in Japan
In the life science, bio-resource as an experimental material is one of the most important fundamentals to secure reproducibility of the experimental results. Phenotype data is also crucial for researchers to choose appropriate experimental materials for their studies. Recently sharing of phenotype data of experimental animals are performed various databases using phenotype ontologies as standardized vocabularies. Using Resource Description Framework (RDF) related technologies, candidates of disease model can be shown through the disease-phenotype relationship between across human, rodents, fish, worms and flies. Therefore, dissemination of phenotype-related information, RDF technologies becomes one of the best solutions. For wider data dissemination of experimental animals produced in Japan, we worked out a data integration project, "J-Phenome" (, to develop RDF data of Japanese bio-resources. I would like to overview the development of RDF datasets and discuss advantage of RDF for sharing phenotype data in Japan and worldwide.

Hiroshi Masuya received PhD in School of Life Science, The Graduate University for Advanced Studies (National Institute Genetics) in 1996. He is currently unit leader of the RIKEN BioResource center. His research interest is development of integrated database of biological phenotype revealing relationships between phenotypes and human diseases using Semantic Web technologies.
Sadao Kurohashi (Kyoto University)
Title: Knowledge-Intensive Structural Natural Language Processing
There have been two obstacles to make machines understand language: lack of knowledge and lack of methodology to utilize knowledge. The former was basically solved by the emergence of the web. A huge volume of texts on the web including Wikipedia have become a resource for knowledge extraction. The latter hard problem also has started to be alleviated by Deep Learning recently. In this talk, I will present our recent research achievements related to knowledge-intensive structural natural language processing.

Sadao Kurohashi received the B.S., M.S., and PhD in Electrical Engineering from Kyoto University in 1989, 1991 and 1994, respectively. He is currently a professor of the Graduate School of Informatics at Kyoto University. His research interests include natural language processing, knowledge acquisition/representation, and information retrieval. He received the 10th and 20th anniversary best paper awards from Journal of Natural Language Processing in 2004 and 2014 respectively, 2009 Funai IT promotion award, and 2009 IBM faculty award.
Yohei Murakami (Kyoto University)
Title: The Language Grid: Towards an Interoperable Language Service Infrastructure Fragmentation and recombination is the key to creating a full range of customized language environments for different types of user activities. Fragmentation provides various components for the customized language environments and recombination builds each language environment according to user's request by combining these components. To realize the fragmentation and recombination process, we proposed the Language Grid by introducing the service-oriented approach to language resource domain. This infrastructure wraps existing language ron.

Title: Semantic sensitive simultaneous tensor factorization and related applications
The semantics distributed over large-scale knowledge bases can be used to intermediate heterogeneous users' activity logs created in services; such information can be used to improve applications that can help users to decide the next activities/services. Since user activities can be represented in terms of relationships involving three or more things (e.g. a user tags movie items on a webpage), tensors are an attractive approach to represent them. The recently introduced Semantic Sensitive Tensor Factorization (SSTF) is promising as it achieves high accuracy in predicting users' activities by basing tensor factorization on the semantics behind objects (e.g. item categories). However, SSTF currently focuses on the factorization of a tensor for a single service and thus has two problems: (1) the balance problem occurs when handling heterogeneous datasets simultaneously, and (2) the sparsity problem triggered by insufficient observations within a single service. Our solution, Semantic Sensitive Simultaneous Tensor Factorization (S3TF), tackles the problems by: (1) Creating tensors for individual services and factorizing them simultaneously; it does not force the creation of a tensor from multiple services and factorize the single tensor. This avoids the low prediction accuracy caused by the balance problem. (2) Utilizing shared semantics behind distributed activity logs and assigning semantic bias to each tensor factorization. This avoids the sparsity problem by sharing semantics among services. Experiments using real-world datasets show that S3TF achieves higher accuracy in rating prediction than the current best tensor method. It also extracts implicit relationships across services in the feature spaces by simultaneous factorization with shared semantics. The presentation also introduces the question and answering system that creates answers for non-factoid questions using the related ideas with the above S3TF. It is practical and has already been applied to the love advice service in Oshiete goo.
