Mobile Novelty Mining

Service-oriented Web applications allow users to exploit applications over networks and access them from a remote system at the client side, including mobile phones. Individual services are built separately with comprehensive functionalities. In this article, the authors transform a standalone offline novelty mining application into a service-oriented application and allow users to access it over the Internet. A novelty mining application mines the novel, yet relevant, information on a topic specified by users. In this article, the authors propose a design for a service-oriented novelty mining application. After deploying their service-oriented novelty mining system on a server, use case scenarios are provided to demonstrate the system. The authors’ service-oriented novelty mining system increases the efficiency of gathering novel information from incoming streams of texts on their mobile devices for users.

Another consequence of the rapid growth of technology is the information overload in the form of news articles, scientific papers, blogs (Chen, Tsai, & Chan, 2008), and social networks (Tsai, Han, Xu, & Chua, 2009). Information is abundantly available on the Internet, where people can find almost anything they desire. However, most of the time, people tend to suffer from information overload because of irrelevant and redundant information in these documents. Therefore, novelty mining (NM), or novelty detection, is a solution to this phenomenon. Novelty mining can be used to solve many solve many business problems, such as in corporate intelligence (Tsai, Chen, & Chan, 2007) and cyber security (Tsai, 2009; Tsai & Chan, 2007). A novelty mining process is a process of retrieving novel yet relevant information, based on a topic given by the user (Ng, Tsai, & Goh, 2007; Ong, Kwee, & Tsai, 2009). To the best of our knowledge, no previous work has been reported in designing and developing a service oriented novelty mining system for the business enterprise. The purpose of creating a Web-based application for the novelty mining system is to offer an online system for users to ease their information burden. This saves time by allowing users to only read novel and relevant information in their topic of interest. For enterprise users, this serviceoriented novelty mining system conveniently helps them to retrieve new information about certain events of interest. They do not need to go through all documents or passages in order to find the novel information. Creating Web services for the novelty mining components facilitates the rapid deployment and availability of these services for these diverse set of users, which can balance technical significance and business concerns in business processes and enterprise systems. The objective of this article is to develop a Web service application i.e. novelty mining system that is used to detect and retrieve any new information of an incoming stream of text to be executed on mobile devices. This article is organized as follows. First, we review recent work on novelty mining. Next, we describe our novelty mining framework, algorithm, and performance evaluation. Then, the architecture and design of the service-oriented novelty mining system are presented. The development of the new system is explained. Two test case scenarios are given to illustrate the service-oriented novelty mining system. Next, we describe the integration of Web service into mobile devices. Finally, the last section summarizes the entire article.
