Integration of mapping web services and scalable vector graphics

The purpose of this project was to develop a web-based application integrating mapping web services and SVG (Scalable Vector Graphics). This project helps a user locate a set of addresses anywhere in the United States on a map. The underlying mapping and address locator software systems are very complex and require large data sets and updates on a regular basis. The web services technology encapsulates tose complexities and exposes the required functionality in a secure manner over the internet

Questions and epistemic stance: Some examples from Italian conversations

Through the analysis of presuppositions, question design, social action and preference organisation in short fragments of Italian question-answer sequences, this paper aims to show that (1) wh-questions, on the one hand, and alternative and polar questions (i.e., polar interrogatives, tag and declarative questions), on the other, come from two different epistemic positions: unknowing and uncertain, respectively; (2) alternative and polar questions convey different degrees of uncertainty, thus placing themselves in different points along the epistemic continuum of the uncertain position. Keywords: Questions, Epistemic stance, Uncertainty, Unknowledge, Information-seeking, Confirmation-seekin

Software reuse environment user's guide

This document describes the services provided by the prototype Software Reuse Environment, which was developed by CTA for NASA Goddard Space Flight Center, Code 520. This is one of three guides delivered by CTA as part of the environment. The other two guides are: Software Generation and Installation Guide; and SEMANTX--Defining the Schema. The Software Generation and Installation Guide describes the software source modules that make up the Reuse Environment, with instructions on how to generate and install an executable system from the source code. SEMANTX--Defining the Schema describes how a reuse database is created. Actually this guide is more general than the reuse database, as it describes how to generate a SEMANTX database. SEMANTX is an off-the-shelf tool that we have used to implement the reuse database. It is a product of Semantyk Systems, Inc. The Software Reuse Environment is built upon SEMANTX as well as on the IDE Structured Analysis Integrated Environment. (IDE is Interactive Development Environments, Inc.) SEMANTX itself is built on top of the Unify Database Management System. To use the Software Reuse Environment you should have the User's Manuals for SEMANTX, for Unify, and for the IDE software. CTA has provided all of these with the environment

PROVIDING INFORMATION SYSTEMS WITH FULL HYPERMEDIA FUNCTIONALITY

The goal of this research is to provide hypermedia functionality to all information systems. In this paper I present the architecture of a system-level hypermedia engine, designed both to manage fill hypermedia functionality for an information system and to bind interface-oriented âfront-end" systems with separate computation-oriented "back-end "systems. The engine dynamically superimposes a hypermedia representation over a back-end application's knowledge components and processes. I then describe a set of minimal requirements for integrating the hypermedia engine. The more sophisticated and cooperative the information system, the higher the level of hypermedia support the engine will provide.Information Systems Working Papers Serie

ON INTEGRATING HYPERMEDIA INTO DECISION SUPPORT AND OTHER INFORMATION SYSTEMS

The goal of this research is to provide hypermedia functionality to all information systems that interact with people. Hypermedia is a concept involving access to information, embodying the notions of context-sensitive navigation, annotation and tailored presentation. We present the architecture of a system-level hypermedia engine, designed both to manage full hypermedia functionality for an information system and to bind interface-oriented front-end systems with separate computation-oriented back-end systems. The engine dynamically superimposes a hypermedia representation over a back-end application's knowledge components and processes. The hypermedia engine generates this representation using bridge laws, which capture the internal structure of client systems. Users access the application through its hypermedia representation. We also describe a set of minimal requirements for integrating our hypermedia engine with an information system. We believe these guidelines apply to all integration efforts, not just our own. Information systems will require some supplementary routines for the engine to manage hypermedia functionality for them. The more sophisticated and cooperative the information system, the higher the level of hypermedia support the engine will provide.Information Systems Working Papers Serie
