Geographical information systems and location science

Since the 1970s the field of Geographical Information Systems (GIS) has evolved into a mature research and application area involving a number of academic fields including Geography, Civil Engineering, Computer Science, Land Use Planning, and Environmental Science. GIS can support a wide range of spatial queries that can be used to support location studies. GIS will play a significant role in future location model development and application. We review existing work that forms the interface between GIS and Location Science and discuss some of the potential research areas involving both GIS and Location Science.Scope and purposeDuring the past 30 years there have been many developments in spatial data analysis, spatial data storage and retrieval, and mapping. Many of these developments have occurred in the field of Geographical Information Science. Geographical Information Systems software now supports many elementary and advanced spatial analytic approaches including the production of high quality maps. GIS will have a major impact on the field of Location Science in terms of model application and model development. The purpose of this paper is to explore the interface between the field of Location Science and GIS.     

The Design and Specification of a Visual Language: An Example for Customising Geographic Information Systems Functionalities

In this paper the design of a visual program editor and its specification using formal grammars are discussed. We consider an environment to specify, analyse and execute visual programs for a Geographical Information System (GIS). The lack of sophisticated user interfaces is one of the major drawbacks to Geographical Information Systems, particularly for people without a sound background in computer science. The use of a visual language approach is useful in order to hide the plethora of basic GIS functions, while providing ready- to-use tools to solve users' tasks. The visual environment provides users with higher level interfaces; it is based on the module concept, which is conceived as a software building block that implements a solution to a general basic task and is presented to the user through an interactive frame. Complex GIS queries can be carried out by interconnecting modules into flow networks, using a direct manipulation approach.     

API2MoL: Automating the building of bridges between APIs and Model-Driven Engineering

Context

A software artefact typically makes its functionality available through a specialized Application Programming Interface (API) describing the set of services offered to client applications. In fact, building any software system usually involves managing a plethora of APIs, which complicates the development process. In Model-Driven Engineering (MDE), where models are the key elements of any software engineering activity, this API management should take place at the model level. Therefore, tools that facilitate the integration of APIs and MDE are clearly needed.

Objective

Our goal is to automate the implementation of API-MDE bridges for supporting both the creation of models from API objects and the generation of such API objects from models. In this sense, this paper presents the API2MoL approach, which provides a declarative rule-based language to easily write mapping definitions to link API specifications and the metamodel that represents them. These definitions are then executed to convert API objects into model elements or vice versa. The approach also allows both the metamodel and the mapping to be automatically obtained from the API specification (bootstrap process).

Method

After implementing the API2MoL engine, its correctness was validated using several APIs. Since APIs are normally large, we then developed a tool to implement the bootstrap process, which was also validated.

Results

We provide a toolkit (language and bootstrap tool) for the creation of bridges between APIs and MDE. The current implementation focuses on Java APIs, although its adaptation to other statically typed object-oriented languages is straightforward. The correctness, expressiveness and completeness of the approach have been validated with the Swing, SWT and JTwitter APIs.

Conclusion

API2MoL frees developers from having to manually implement the tasks of obtaining models from API objects and generating such objects from models. This helps to manage API models in MDE-based solutions.     

Tradeoff and Sensitivity Analysis in Software Architecture Evaluation Using Analytic Hierarchy Process

Software architecture evaluation involves evaluating different architecture design alternatives against multiple quality-attributes. These attributes typically have intrinsic conflicts and must be considered simultaneously in order to reach a final design decision. AHP (Analytic Hierarchy Process), an important decision making technique, has been leveraged to resolve such conflicts. AHP can help provide an overall ranking of design alternatives. However it lacks the capability to explicitly identify the exact tradeoffs being made and the relative size of these tradeoffs. Moreover, the ranking produced can be sensitive such that the smallest change in intermediate priority weights can alter the final order of design alternatives. In this paper, we propose several in-depth analysis techniques applicable to AHP to identify critical tradeoffs and sensitive points in the decision process. We apply our method to an example of a real-world distributed architecture presented in the literature. The results are promising in that they make important decision consequences explicit in terms of key design tradeoffs and the architecture's capability to handle future quality attribute changes. These expose critical decisions which are otherwise too subtle to be detected in standard AHP results.

Specification and Standardization of a Java Trusted Computing API

The paradigm of Trusted Computing promises a new approach to improve the security of computer systems. The core functionality, based on a hardware component known as Trusted Platform Module, is integrated into commodity hardware. However, operating system integration and application software support remains limited at present. In particular, for Java, the most widely used platform‐independent computing environment, there is currently no generally accepted Trusted Computing API. In this article, we describe the design of a high‐level API for Trusted Computing. We report on the current state of the Trusted Computing Group's software architecture and on previous approaches targeting Java. We derive our requirements and design goals and describe a novel API design. We report on our transparent approach to standardization in the Java Community Process. The result of this effort is the API we propose in the Java Specification Request 321. In this work, we not only present the design of this new API but also discuss implementation and testing strategies. Copyright © 2011 John Wiley & Sons, Ltd.

Application of Text Summarization techniques to the Geographical Information Retrieval task

Automatic Text Summarization has been shown to be useful for Natural Language Processing tasks such as Question Answering or Text Classification and other related fields of computer science such as Information Retrieval. Since Geographical Information Retrieval can be considered as an extension of the Information Retrieval field, the generation of summaries could be integrated into these systems by acting as an intermediate stage, with the purpose of reducing the document length. In this manner, the access time for information searching will be improved, while at the same time relevant documents will be also retrieved. Therefore, in this paper we propose the generation of two types of summaries (generic and geographical) applying several compression rates in order to evaluate their effectiveness in the Geographical Information Retrieval task. The evaluation has been carried out using GeoCLEF as evaluation framework and following an Information Retrieval perspective without considering the geo-reranking phase commonly used in these systems. Although single-document summarization has not performed well in general, the slight improvements obtained for some types of the proposed summaries, particularly for those based on geographical information, made us believe that the integration of Text Summarization with Geographical Information Retrieval may be beneficial, and consequently, the experimental set-up developed in this research work serves as a basis for further investigations in this field.

Ginger2: an environment for computer-aided empirical softwareengineering

Empirical software engineering can be viewed as a series of actions to obtain knowledge and a better understanding about some aspects of software development, given a set of problem statements in the form of issues, questions or hypotheses. Experience has made us aware of the criticality of integrating the various types of data that are collected and analyzed as well as the criticality of integrating the various types of activities that take place, such as experiment design and the experiment itself. This has led us to develop a Computer-Aided Empirical Software Engineering (CAESE) framework to support the empirical software engineering lifecycle. The paper first presents the CAESE framework that consists of three elements: (1) a process model for the “lifecycle” of empirical software engineering studies, including needs analysis, experiment design, actual experimentation, and analyzing and packaging results; (2) a model that helps empirical software engineers decide how to look at the “world” to be studied in a coherent manner; (3) an architecture, based on which CAESE environments can be built, consisting of tool sets for each phase of the process model, a process management mechanism, and the two types of integration mechanism that are vital for handling multiple types of data: data integration and control integration. Next, the paper describes the Ginger2 environment as an instantiation of our framework. It concludes with reports on case studies using Ginger2, which dealt with a variety of empirical data types including mouse and keystrokes, eye traces, 3D movement, skin resistance level, and videotaped data
