It is concerned with the elicitation of stake-holders goals, the elaboration of these goals into requirements on the software behavior, and the assignment of responsibilities for these requirements to agents . Inadequacy in the execution of any of these RE subtasks inevitably leads to development problems which are often difficult and costly to repair. This […]
Ontology- Language based in multi -facet (OMF) framework
The last decade, there has been tremendous growth in the field of network. The information served to the internet users through web is enormous. Some information provided is of use to the end users, and others of no use to them. Current web information gathering systems attempt to satisfy user requirements by capturing their information […]
The efficient minimum-spanning tree clustering Algorithm method
The aim of choosing a subset of good features with respect to the target concepts, feature subset selection is an effective way for reducing dimensionality, removing irrelevant data, increasing learning accuracy, and improving result comprehensibility. Many feature subset selection methods have been proposed and studied for machine learning applications. They can be divided into four […]
OSNs provide and prevent unwanted messages on user walls
On-line Social Networks (OSNs) are today one of the most popular interactive medium to communicate, share and disseminate a considerable amount of human life information. Daily and continuous communications imply the exchange of several types of content, including free text, image, audio and video data. Facebook statistics1 average user creates 90 pieces of content each […]
Mobile presence services for large-scale social network services
The ubiquity of the Internet, mobile devices and cloud computing environments can provide presence-enabled applications, social network applications/services, worldwide. Facebook, Twitter, Foursquare, Google Latitude, buddy cloud and Mobile Instant Messaging (MIM), are examples of presence-enabled applications that have grown rapidly in the last decade. Social network services are changing the ways in which participants engage […]
Tweets Monitored to detect a target event of social sensor in location estimation
Twitter, a popular microblogging service, has received much attention recently. This online social network is used by millions of people around the world to remain socially connected to their friends, family members, and coworkers through their computers and mobile phones. Twitter asks one question, “What’s happening?” Answers must be fewer than 140 characters. A status […]
Idealized security requirements: impersonation, collusion, and privacy breaching
The conventional model of social networks, users select their contacts from a set of off-line acquaintances. Despite their utility, these conventional networks support only a subset of social networking: two users will only be able to establish a relationship in the social network if they , or are introduced to each other. One more Encounter […]
Active Discovery And Imblanced Learning in Generative-Discriminative models
The vast majority of sky survey image content is due to well understood phenomena, and only 0.001% of data is of interest for astronomers to study. Computer network intrusion detection exhibits vast amounts of normal user traffic, and a very few examples of malicious attacks. In computer vision based security surveillance of public spaces, observed […]
Privacy Preservation in distributed social network using clustering technique
Networks are structures that describe a set of entities and the relations between them. A social network, for example, provides information on individuals in some population and the links between them, which may describe relations of friendship, collaboration, correspondence and so forth. An information network, as another example, may describe scientific publications and their citation […]
CF-based web service recommender systems and QoS space visualization
Web services are software components designed to support interoperable machine-to-machine interaction over a network. The adoption of web services as a delivery mode in business has fostered a new paradigm shift from the development of monolithic applications to the dynamic setup of business process. The number of public web services is steadily increasing. Implementing service-oriented […]
