One of the most important research topics concerns improving the selection of \"interesting\" Web pages (for the user), according to importance metrics. Another relevant point is content freshness, i.e. maintaining freshness and consistency of temporary stored copies. For this, the crawler periodically repeats its activity going over stored contents (recrawling process). We propose a scheme to permit a crawler to acquire information about the global state of a Website before the crawling process takes place. This scheme requires Web server cooperation in order to collect and publish information on its content, useful for enabling a crawler to tune its visit strategy. If this information is unavailable or not updated the crawler still acts in the usual manner. In this sense the proposed scheme is not invasive and is independent from any crawling strategy and architecture.","PeriodicalId":376743,"journal":{"name":"Proceedings of the IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices (IEEE Cat.

There are various useful recently-issued ISO standards related to software quality models, measurement and evaluation processes, however, we observe sometimes a lack of a sound consensus among the same terms in different documents or sometimes absent terms. We present an ontology for software metrics and indicators-based as much as possible on the concepts of those standards, which can be useful to support different assurance processes, methods and tools in addition to being the foundation for our cataloging Web system [Olsina, L et al., (2003)]. Without sound and consensuated definitions it is difficult to assure metadata consistency and, ultimately, data values are comparable on the same basis.","PeriodicalId":376743,"journal":{"name":"Proceedings of the IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices (IEEE Cat.

From this study, a set of design rules has been obtained. These rules help the modeler to build navigational models in a systematic way.

Based on these actions, a finite automaton of fine-grained authorization checks, may be specified in a separate layer that is easily configurable for security needs of a particular application. In the Mobile case there may be two such state machines - one performing state-based authorization checks of the application execution process and the other performing such checks for the mobile agent execution process. Authorization checks of these machines may be both state-based and policy based, and the policies should distinguish between human clients and mobile agents cases. We develop the framework to specify and enforce finegrained state-based authorization checks of Web application execution, consisting of a Web browser (client) and a server. We adopt this framework to the mobile case so that state machines representing finegrained authorization checks of application and mobile agent execution are synchronized.","PeriodicalId":376743,"journal":{"name":"Proceedings of the IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices (IEEE Cat.
