Recent research has been focused on the creation of intelligent compositional systems that utilize ontologies as a knowledge base to facilitate the composition of new systems/workflows. Within this “ontology-driven” compositional systems field, experts have created knowledge representation models to satisfy requirements of their own domain rather than considering a general perspective. This paper...
Phenotypic comparison may provide crucial information for obtaining insights into molecular interactions underlying various diseases. However, few attempts have been made to systematically analyze the phenotypes of hereditary disorders, mainly owing to the poor quality of text descriptions and lack of a unified system of descriptors. Here we present a secondary database, PHENOMIM, for translating...
Current collaboration technologies encompass a broad range of tools that enable groups of people to work together and collaboratively create and manage knowledge. To facilitate the efficient use of collaboration tools, patterns have been exploited as models for repeatable collaboration processes for recurring high-value collaborative tasks. We present Collaboration Patterns Assistant, a software tool...
Fine-grained software configuration management has been proven to offer substantial benefits for software development in many fields, overcoming developmental problems, such as complexity management and support for communication and coordination, among others. The same problems exist in a collaborative ontology development environment that uses a simple versioning and configuration management system...
Thanks to ICT, Web emergency and Internet, the achievement of maintenance services and monitoring can be performed automatically, remotely and through various distributed information systems. Hence the emergence of the concept of services offered through maintenance architectures, ranging from autonomic systems to integrated systems where knowledge management, cooperation and collaboration are vital...
The majority of cellular functions can rarely be attributed to a single protein, gene or enzyme. Protein-protein interactions are fundamental to most of cellular processes or functions. Hubs, proteins with high connectivity, mediate the organization and function of cellular protein interaction networks (PINs). As a first step, research on hub proteins starts with classification. Although there are...
Electronic negotiations are business negotiations conducted via electronic means using information and communications technologies (ICT). Two dominant types of electronic negotiation systems are automated negotiation systems for software agents and negotiation support systems (NSSs) for humans. However, the integration of two types for human-agent negotiations is an important task. In this paper,...
Semantic web technologies provide a standardised mechanism for describing and accessing the services of underlying infrastructure. These technologies facilitate the inclusion of the quality of network services in the control loop of high level applications and allow applications to tune the system level performance with additional quality dimensions. However, the descriptions of a large infrastructure...
This article introduces a model for representing motion primitives for entertainment humanoid robots using Generalized Hierarchical AND/OR graphs. On the one hand, the goal is to drive robots with scripts, as if they were on a stage. On the other hand, the approach allows for storing a minimum amount of behaviours, thereby reducing on-board memory and computational requirements. Standard ontology-based...
Information on web and in use of web services is increasing enormously even on hourly bases. On semantic web the information is represented in ontology. For system and services to share the information, a sort of mediation (i.e., mappings) is required. Mappings are established between the ontologies (information sources) of web services for resolving the terminological and conceptual incompatibilities...
Typhoon disaster is a complex system in which the environmental possibilities with hazard (EPH) and the bodies bearing disasters (BBD) are various. And different disasters caused by typhoon not only have their own laws of occurring, developing and turning into disasters, but also have explicit relationships among them. As a modeling tool describing concepts on semantic and knowledge level, ontology...
The cyber-physical society is a complex space where human abilities are extended to various spaces by coordinating the cyber space, physical space, socio space and mental space. A challenge issue is to seek the uniformity in managing resources in these spaces. This keynote introduces a complex semantic space model that is suitable for managing various resources in different spaces in the cyber-physical...
This paper illustrates a web-based infrastructure of an architecture for conversational agents equipped with a modular knowledge base. This solution has the advantage to allow the building of specific modules that deal with particular features of a conversation (ranging from its topic to the manner of reasoning of the chatbot). This enhances the agent interaction capabilities. The approach simplifies...
This paper describes the process of deriving the meaning of an unknown word within the framework of meaning based natural language processing. It uses the clues supplied by the rest of the sentence, taking into account various degrees of possibilities of what the unknown word can mean, according to the previously acquired knowledge resources. The process of finding the meaning is incremental, and...
Fuzzy Description Logics (Fuzzy DLs) are logics that allow to deal with structured knowledge affected by fuzziness. Fuzzy DLs are at the heart of Fuzzy OWL 2, a fuzzy version of the standard ontology language OWL 2. Although a relatively important amount of work has been carried out in the last years, fuzzy DLs are open to be extended with several features worked out in other fields. In particular,...
Computation of Semantic similarity between concepts play a key role in Ontology mapping, Psycholinguistics, Information Integration and Information Retrieval. A COSS (Cross Ontology Semantic Similarity) measure which follows information content approach and is based on Amos Tversky psychological contrast model for finding the semantic closeness of concepts belonging to different biomedical ontologies...
This paper presents a description logic based system to store and retrieve knowledge used in models for autonomous probabilistic decision making by multimodal service robots. These models are mainly generated by observation and analysis of humans performing tasks, the programming by demonstration methodology. As formal model representation, partially observable Markov decision processes (POMDPs) are...
Transforming database schemas into an ontology language opens the door wide to the many advantages offered by the Semantic Web. Industries in particular can benefit from intelligent systems (e.g., decision-support systems) arising from such transformations. In this paper, we propose a semi-automated algorithm to transform data to the ontology language, OWL, while taking advantage of the actual data...
This article describes our work in progress and deals with methods and approaches for handling internal complexity emerging in highly realistic models of human behaviour. We present a new modelling approach to human decision making along with a conceptual design of several methods targeting selected aspects of complexity, such as the combinatorial explosion of action alternatives in rich environments,...
