The Development and the Evaluation of a System for Extracting Events from Web Pages

The centralization of a particular event is primarily useful for running news services. These services should provide updated information, if possible even in real time, on a specific type of event. These events and their extraction involved the automatic analysis of linguistic structure documents to determine the possible sequences in which these events occur in documents. This analysis will provide structured and semi-structured documents in which the unit events can be extracted automatically. In order to measure the quality of a system, a methodology will be introduced, which describes the stages and how the decomposition of a system for extracting events in components, quality attributes and properties will be defined for these components, and finally will be introduced metrics for evaluation.Event, Performance Metric, Event Extraction System

MODEL DRIVEN DEVELOPMENT OF ONLINE BANKING SYSTEMS

In case of online applications the cycle of software development varies from the routine. The online environment, the variety of users, the treatability of the mass of information created by them, the reusability and the accessibility from different devices are all factors of these systems complexity. The use of model drive approach brings several advantages that ease up the development process. Working prototypes that simplify client relationship and serve as the base of model tests can be easily made from models describing the system. These systems make possible for the banks clients to make their desired actions from anywhere. The user has the possibility of accessing information or making transactions.MDA, UML, Online Banking, Class diagram, Platform Independent Model

Platform paradigm: fluid flow on online platforms

Az elmúlt évtizedben az online platformok soha nem látott ütemben fejlődtek és nemcsak a gazdaságot, hanem a mindennapi életünket is alaposan megváltoztatták. Az online platformok korában a mindennapi szokásaink, a vállalatok lehetőségei és munkaerőpiac szerkezete is jelentős átalakulásokon megy át. A napjainkban használt technológia, amely az életünk szinte minden területét behálózza, nagyon rövid idő alatt fejlődött ki. Mivel szinte bárhol a világon internetkapcsolatot létesíthetünk, valamint a böngészők is könnyen elérhetők, ezért nem nagyon érdekel bennünket, hogy hol fut vagy miként van valójában egy adott rendszer, amelyet éppen használunk [1]. A leggyakrabban a YouTube-ot vagy éppen a Facebook-ot használjuk [3]. Ezek online platformok. Minket falhasználókat pedig az érdekel, hogy ezek a „szolgáltatások” gyorsan és lehetőleg ingyen legyenek elérhetők

Developing web applications using the MDA paradigm

Data intensive web based systems, that in the most of their uptime do data processes have become a part of our everyday life. Several systems of this type appeared on the internet: webshops, online ticket shops, banks, etc. These are used everyday by users around the worls. The use of model drive approach brings several advantages that ease up the development process. Working prototypes that simplify client relationship and serve as the base of model tests can be easily made from models describing the system. These systems make possible for the banks clients to make their desired actions from anywhere. The user has the possibility of accessing information or making transactions

CONSIDERATIONS ON OBJECTIVE METHODS FOR DEVELOPING APPLIED EVENT EXTRACTION SYSTEMS

There are several similarities between designing classic systems and systems for event extraction. Similarities derive from the use of common methodology in designing and developing these systems. The system is intended to be a helpful instrument when looking for pieces of informationon different web pages or when in case of a special type of event,information needs to be centralized. Use-case diagrams need to be designed through both methods. The relationships between classes have to be identified and described. Differences induced by the design process are due to the special character of a web based data exchange

DESIGNING AN EVENT EXTRACTION SYSTEM

In the Internet world, the amount of information available reaches very high quotas. In order to find specific information, some tools were created that automatically scroll through the existing web pages and update their databases with the latest information on the Internet. In order to systematize the search and achieve a result in a concrete form, another step is needed for processing the information returned by the search engine and generating the response in a more organized form. Centralizing events of a certain type is useful first of all for creating a news service. Through this system we are pursuing a knowledge - events from the Internet documents - extraction system. The system will recognize events of a certain type (weather, sports, politics, text data mining, etc.) depending on how it will be trained (the concept it has in the dictionary). These events can be provided to the user, or it can also extract the context in which the event occurred, to indicate the initial form in which the event was embedded

BUSINESS MODELLING AND DATABASE DESIGN IN CLOUD COMPUTING

Electronic commerce is growing constantly from one year to another in the last decade, few are the areas that also register such a growth. It covers the exchanges of computerized data, but also electronic messaging, linear data banks and electronic transfer payment. Cloud computing, a relatively new concept and term, is a model of access services via the internet to distributed systems of configurable calculus resources at request which can be made available quickly with minimum management effort and intervention from the client and the provider. Behind an electronic commerce system in cloud there is a data base which contains the necessary information for the transactions in the system. Using business modelling, we get many benefits, which makes the design of the database used by electronic commerce systems in cloud considerably easier
