In this paper, we propose two different alternatives to deal with degraded queries on Spanish Information Retrieval applications. The first is based on character n-grams, and has no dependence on the linguistic knowledge and resources available. In the second, we propose two spelling correction techniques, one of which has a strong dependence on a stochastic model that must be previously built ...

Interoperability has been identified as a major issue to be addressed by every egovernment initiative. In order to tackle this issue, egovernment agencies have developed tools to facilitate the interchange of information between agencies when providing public services to citizens and businesses through internet. The tools are called frameworks. The chapter surveys a sample of egovernment agenci...

This paper continues our work on the analysis and formalization of enterprise architecture frameworks, proposing a number of principles related to the construction and use of these frameworks. These principles are intended to guide the development of a formal foundation for frameworks. Enterprise architecture frameworks organize, manage, and interrelate the wide variety of models used to struct...

Software frameworks typically constitute a semi-finished software architecture for a complex application domain that can be adapted to the needs and requirements of a concrete application in the domain. Since the introduction of objectoriented frameworks in the late eighties, the development of software frameworks is still costly and difficult to handle. To reduce development risk, process mode...

Verbesserungen in der Software-Entwicklung basieren auf der Annahme, dass Fehler günstiger zu beheben sind, wenn sie möglichst früh entdeckt werden [Boe76,Boe87]. Erfahrungsberichte bestätigen diesen Zusammenhang [Bas84, Hum95, Kan03, Shu02]. Aktuelle oder detaillierte Zahlen liegen aber nicht vor. Darum ist zum Beispiel unklar, ob und wie sich ein objektorientiertes Vorgehen auswirkt und welch...

Many works have shown colorimetric additivity failures in colour-matching experiments. Thus, in the present work, using the colour-matching functions (CMF) of three real observers, we have conducted five experiments in isomeric and metameric matching. The stimuli matched, using two modified Donaldson colorimeters, were two achromatic, one blue, one orange and one green. Afterwards, we determine...

Knowledge Intensive Organisations (KIOs), that is organisations built on their use intellectual capital, need to create an environment that facilitates the effective deployment and reuse of existing organisational knowledge. As people transform data, information and experiences into shared knowledge, the management of individual competencies has become increasingly important to these organisati...

JavaScript is today’s most common client-side programming language for the web. Choosing the most adapted framework for each and every project can optimize the development process and increase profits. Developers often lack knowledge about what to prioritize when choosing a framework and very little previous research regarding this subject area is available. This thesis investigates two JavaScr...
