Item Combining Hierarchical Filtering, Fuzzy Logic, and Simulation with Software Agents for IP (Intellectual Property) Selection in Electronic Design(2000-02-04) Liu, Jian; Shragowitz, Eugene; Tsai, Wei-TekOne of the central issues in electronic design is reuse of existing design solutions (IPs). This paper describes an Internet-based distributed system of software agents, performing dialogue with the users, search of IPs over Internet, filtering and evaluation of IPs based on fuzzy logic and vendor site simulation environment. Application of this system allows the potential user to speed up the search process and improve the quality of selected solutions.Item Network Publishing Paradigm: A Web Authoring and Publishing Methodology for Internet Commerce(1997) Koo, Benjamin; Poonawala, Mustafa; Tsai, Wei-Tek; Qiu, ElimThis paper presents a Network Publishing Paradigm (NPP) as a framework for building large scale Internet and Intranet (INED systems. It changes the traditional function-centered infonnation systems design paradigm by integrating content-centered design disciplines. NPP also categorizes the web site construction tasks into five different domains. We propose a layered methodology for web authoring where each domain is mapped onto a specific software layer. To maximize the utilization of layered software architecture, NPP modularizes technical elements and packages human expertise into interchangeable units that allow the construction of network publishing environments to be highly flexible and scaleable. These qualities, coupled with secure production protocols, are essential to commercial transactions on the INET. The NPP is a comprehensive development methodology that enables organizations to adopt late breaking technologies with minimal financial risks and managerial uncertainty.Item Servicetizing User Experiences for Complex Business Applications(2006-08-07) Liang, Donglin; Tsai, Wei-TekWeb interfaces have been widely used to support user interactions in complex business applications. In a typical design of such an application, the execution is driven by the http requests sent by the web-browser. Thus, the control of the workflow is encoded by the hyperlinks and buttons embedded in various web pages that support the user interactions. This web-driven design makes it hard to reason about and to maintain the workflows, especially when the web pages are dynamically generated at runtime. This design also increases the complexity in developing rich user interactions for complex workflows. In this paper, we propose a new design that separates the workflow specification from the user interaction specification in a business application. This design is based on a workflow-driven service-oriented architecture pattern. In this architecture, the user interactions are captured by user experience services that can be developed, deployed, and maintained independently of the application. These services can be composed together with other business services by an executable workflow specification to provide the functionalities required by the application. This approach increases the flexibility in the implementation of the user interactions. It also enables a model-driven development approach for implementing the workflows that involve sophisticated user interactions.
