Multi-dialect Workflows

Abstract: The results presented in this paper contribute to the techniques for conceptual representation of data analysis algorithms as well as processes to specify data and behavior semantics in one paradigm. An investigation of a novel approach for applying a combination of semantically different platform independent rule-based languages (dialects) for interoperable conceptual specifications over various rule-based systems (RSs) relying on the rule-based program transformation technique recommended by the W3C Rule Interchange Format (RIF) is extended here. The approach is coupled also with the facilities for heterogeneous information resources mediation. This paper extends a previous research of the authors [1] in the direction of workflow modeling for definition of compositions of algorithmic modules in a process structure. A capability of the multi-dialect workflow support specifying the tasks in semantically different languages mostly suited to the task orientation is presented. A practical workflow use case, the interoperating tasks of which are specified in several rule-based languages (RIF-CASPD, RIF-BLD, RIF-PRD) is introduced. In addition, OWL 2 is used for the conceptual schema definition, RIF-PRD is used also for the workflow orchestration. The use case implementation infrastructure includes a production rule-based system (IBM ILOG), a logic rule-based system (DLV) and a mediation system.

Editorial: Accessing Conceptual Representations for Speaking

Abstract: Systematic investigations into the role of semantics in the speech production process have remained elusive. This special issue aims at moving forward toward a more detailed account of how precisely conceptual information is used to access the lexicon in speaking and what corresponding format of conceptual representations needs to be assumed. The studies presented in this volume investigated effects of conceptual processing on different processing stages of language production, including sentence formulation, lemma selection, and word form access.

The Internal Representation of Curriculum-Based Conceptual Systems

Abstract: Publisher Summary This chapter discusses the internal representation of curriculum-based conceptual systems. A decisive role in psychological memory research is being played by studies of the attainment and internal representation of natural concepts and conceptual systems. The purpose of the study is to demonstrate the possibilities of an invariant structural description of well-defined natural conceptual systems and to test its validity by way of experiment. By a natural conceptual system, a linguistically labeled and induced conceptual structure is described whose elements are concepts over which inter-conceptual, mostly asymmetrical relations are defined. The attribute “natural” is to denote that a well-defined realm of reality is represented in this conceptual system, and the system term is to denote that conceptual organization is based on structure-forming principles. There are a wide variety of principles of the structuring of conceptual systems and, hence, their internal organization. Depending upon whether either a functionally or a taxonomically defined organizing principle is adopted as determining structure, roughly two types of conceptual systems are differentiated as subjects of psychological studies.

Improved Database Schema Development for OWL2

Abstract: This paper proposes a novel approach to storing ontologies in relational databases. The approach consists of a database schema, which was created to be capable of storing ontology information defined in OWL2 (Web Ontology Language 2) functional syntax. The paper explains how the schema has been designed and what advantages it offers to any user. The described schema is part of a larger system. This paper also discusses how the schema cooperates with the external system, which, however, is outside the scope of this paper, to successfully create, store and retrieve ontology knowledge from the functionality offered by the relational database. Further, this paper describes the implementation of the proposed method in prototype software. The described schema shall be the first step of the creation of an ontology-based database access system.
