Three forms of contextual search have been proposed in the literature. The first one is to scan the full text of a query to figure out user needs and based on that scan, HTML pages for content will return an index of the relevant content. In this case, the user has no control over the context of the query. The second form of contextual search is used by meta-search engines and requires the user to...
Retail data available for consumer-oriented company is a precious asset which can deliver useful insights in decision making and marketing strategy. KID (DataInformation-Knowledge) model which is a generic from data to knowledge cognitive model can be applied to retail business for supporting retail data analytics. The core part of KID model is the knowledge repository which should be designed to...
Web search engine provides information for the submitted query of the users, without consideration of user's interests. Personalized Web search is used to consider the user interests for providing the results. Existing research Link-click-concept based ranking (LC2R) algorithm is suggested that extracts a user's conceptual preferences from users' click through data resulted from web search. This preference...
The emerging growth and evolution of web based systems and services make the job of audit professionals a complicated and time-consuming one for many enterprises. In this context, continuous process auditing (CPA) systems in the form of audit-as-a-service (AaaS) emerges as an inexpensive and effective approach. A CPA system helps to satisfy process auditing needs and recommendations in the context...
As ever more data is collected in the business processes of large enterprises, the decision makers need new business intelligence tools. Enterprise reporting tools have been available for some time, however, while reports aggregate business data, the large number of reports can become unmanageable. The European funded project Questor aims to create a revolutionary product that will eliminate the complexities...
Web service compositions run in changing environment where different context events can arise to affect the execution of services. In order not to make service execution affected by context events, context-aware service composition becomes one of the major research trends. Service providers can develop context-aware services which can adapt their behaviors dynamically to execution contexts. However,...
Over the past few years, Cloud computing has been receiving much attention as a new computing paradigm for providing flexible and on-demand infrastructures, platforms and software as services. In Cloud computing, challenges in searching cloud services need to be renewed due to a number of unique characteristics of cloud services such as the dynamic, diverse services offering at different levels, as...
Vast arrays of reporting are nowadays in use, allowing ever increasing flexibility and control over the displayed results. However, as IT developed and became available to all business domains, the number of reports used by companies started to challenge the possibility of good management. The European funded project Questor aims to create a revolutionary product that will eliminate the complexities...
Semantic web search engine is the new generation of conventional web search engine that brings precise and meaningful information from the Internet. These new search engines answer user queries using Semantic Web Documents (SWDs) that are found in ontologies database. It is likely that a query may have more than one range in a domain. The semantic web search engines such as Hakia, Swoogle, and Watson...
Nowadays situation assessment in various scenarios depends on communication networks, information stored in various data stores (information networks), and knowledge of the roles and relations that particular people are involved in (social networks). In order to come up with a high-fidelity situation assessment, information from these three networks must be integrated consistently into a coherent...
A language contains complex history and knowledge of human kinds. Hence, we have to conserve the language in order to conserve the history and knowledge of our ancestors to the next generation. Currently, there are a lot of local languages that are endangered due to the extensive use of national language in daily practices. This could make us losing of historical and knowledge richness from our local...
Capturing a domain of discourse in an object-oriented class model and in a reference ontology leads to different results. On the one hand, modeling decisions for class models are motivated by pragmatic and efficiency-related choices because modeling decisions are motivated by different choices. However, information integration scenarios require a coexistence between reference ontologies and class...
The web size is increasing continuously. Chinese researchers have shown that web growth obeys the Moor's law and the Internet will double in size every 5.32 years. The more the Internet is growing; the more tendencies the people have to use the search engines. Moreover, since most of the commercial search engines are based on keyword indexing, there are many records in their result lists that are...
With the rapid development of computer technologies and medical industries, the sharing and exchanging of medical information has become increasingly important. A framework for integrating heterogeneous, diverse and various medical information systems based on Health Level 7(HL7), ontology and Web services is proposed in this paper. In the paper, we describe the framework architecture, module function,...
Policing a wireless network is an evolving and exciting paradigm, specially emphasized with the emergence of cognitive radio networks. The possibility to manage radio resources efficiently and achieve different goals imposed by different stakeholders with dynamically changing policies in a wireless network is the main advantage of the policy based cognitive system. Moreover, the ability to express...
With the increase of the number of independent database applications, Large organizations are eager to an effective solution of heterogeneous and distributed databases integration. Ontology is defined as an explicit formal specification of a shared conceptualization. It can provide semantics through relations between concepts and can be widely used on heterogeneous data. This paper mainly discusses...
Compare with SOAP-based service that based on interfaces access pattern, RESTful web service is HTTP-based and use resource as the operation object. On the purpose of supporting RESTful in the enterprise information application, a Resource-oriented Information Supported Framework is constructed based on ontology construction and evolution. First, the initial ontology with relational pattern is extracted...
In order to implement the quick discovery of metadata information on the grid system and to improve the utilization ratio of the resource as well as handle up the rate of the system, a novel metadata information discovery mechanism based on grid has been designed and implemented after the study on the grid. Firstly, VOMS (virtual organization metadata system) mode has been proposed, which adopts an...
The communication between the teachers and students is very important in network education. Question-answering system can resolve the problem. This paper proposes a question answering platform in network education and then introduces the kernel module which is the answer extraction based on FAQ and ontology in detail. The paper describes the similarity algorithm between the student question and the...
Current many information retrieval methods are based on purely keywords for representing the user needs. One of the main problems with this method is that it does not formally capture the explicit meaning of a keywords query, and ignores the documents that may be different in content but related with them. To improve the precision of the information retrieval, this paper proposes a hybrid method for...
