Testing the weighted salience model of conceptual combinationPatterson, Merryl Joy 30 September 2004 (has links)
In two experiments the Weighted Salience Model (WSM) of conceptual combination was examined. Several of the hypotheses set forth in the WSM were evaluated, including the importance of salience of constituent features, differential interpretation strategies based on similarity, an initial reliance on the modifier as opposed to the head, and a context effect of salience reorganization. Results confirmed that the hierarchy of output dominance within constituent features was important in determining features in final combinations. Additionally, similar pairs were defined with property interpretations more frequently than were dissimilar pairs, and dissimilar pairs were defined with relation interpretations more frequently than were similar pairs. Context effects were demonstrated through the finding that target features were found more often in primed than unprimed pairs. The hypothesis of modifier superiority was not confirmed. These findings indicate that the WSM adds to the current understanding of conceptual combination through a reliance on output dominance and the importance of context. Despite these strengths, changes to the WSM may be necessary if future studies fail to support the importance of the modifier over the head noun.

Using patterns in conceptual modeling of business activitiesHe, Feihu 11 1900 (has links)
Patterns are used as building blocks for design and construction in many fields such as
architecture, music, literature, etc. Researchers and practitioners in the information
systems area have been exploring patterns and using them in system analysis and design.
Patterns found in the analysis stage, when analysts create conceptual models to abstractly
represent domain reality, are call business patterns or analysis patterns. Although various
business patterns were proposed in previous studies, we found that business semantics
were missing in these patterns. These business patterns failed to show functionalities that
is essential to patterns in general. Most of these patterns were also not capable of
describing business activities, the dynamic aspect of business. This study is conducted to
address these issues. In this thesis, we provide a brief literature review on business
patterns, and discuss the major problems we found in these studies. Then we introduce
our research approach and the major outcomes. We propose a new definition of business
patterns with business semantics, which enables us to recover the missing functionality in
business patterns. We suggest the key elements to represent business patterns, and
propose a two-level template (functional and operational) to describe these elements.
Based on theR²M approach, we propose a modeling method with graphical notations to
describe the operational level of patterns, where business activities can be modeled.
Examples and a case study are provided in this thesis to demonstrate how to use the
modeling method and how to use business patterns in practice.

Previous issue date: 2015-05-28 / Conceptual models often capture the invariant aspects of the phenomena we perceive. These invariants may be considered static when they refer to structures we perceive in phenomena at a particular point in time or dynamic/temporal when they refer to regularities across different points in time. While static invariants have received significant attention, dynamics enjoy marginal support in widely-employed techniques such as UML and OCL. This thesis aims at addressing this gap by proposing a technique for the representation of dynamic invariants of subject domains in UML-based conceptual models. For that purpose, a temporal extension of OCL is proposed. It enriches the ontologically well-founded OntoUML profile and enables the expression of a variety of (arbitrary) temporal constraints. The extension is fully implemented in the tool for specification, verification and simulation of enriched OntoUML models.

Generic evolutionary design of solid objects using a genetic algorithmBentley, Peter John January 1996 (has links)
This thesis investigates the novel idea of using a computer to create and optimise conceptual designs of a range of differently-shaped three-dimensional solid objects from scratch. An extensive literature review evaluates all related areas of research and reveals that no such system exists. The development of a generic evolutionary design system, using a genetic algorithm (GA) as its core, is then presented. The thesis describes a number of significant advances necessitated by the development of this system. Firstly, a new low-parameter spatial-partitioning representation of solid objects is introduced, which allows a wide range of solid objects to be appropriately defined and easily manipulated by a GA. Secondly, multiobjective optimisation is investigated to allow users to define design problems without fine-tuning large numbers of weights. As a result of this, the new concepts of acceptability, range-independence and importance are introduced and a new multiobjective ranking method is identified as being most appropriate. Thirdly, variable-length chromosomes in GAs are addressed, to allow the number of primitive shapes that define a design to be variable. This problem is overcome by the use of a new hierarchical crossover operator, which uses the new concept of a semantic hierarchy to reference chromosomes. Additionally, the thesis describes how the performance of the GA is improved by using an explicit mapping stage between genotypes and phenotypes, steady-state reproduction with preferential selection, and a new lifespan limiter. A library of modular evaluation software is also presented, which allows a user to define new design problems quickly and easily by picking combinations of modules to guide the evolution of designs. Finally, the feasibility of the generic evolutionary design of solid objects is demonstrated by presenting the successful evolution of both conventional and unconventional designs for fifteen different solid-object design tasks, e.g. tables, heatsinks, penta-prisms, boat hulls, aerodynamic cars.
