Rich metadata searches using the JXTA content manager service

Abstract: With the development of networking technologies and the advent of the peer-to-peer computing paradigm, distributed file-sharing systems like Gnutella are becoming prevalent over time. JXTA, an interoperable and platform independent peer-to-peer computing infrastructure, has been adopted in an increasing number of network applications providing file-sharing and cooperative service. In this paper, we propose the metadata search layer which serves as an enhancement to the CMS (content manager service), a JXTA-based file-sharing service. Through the metadata search layer, more precise search of resources could be conducted as opposed to the inflexible keyword-based search mechanism employed in most of current file-sharing applications in use. A compact general-purpose query language is proposed to facilitate the use of standard metadata schema and bridge the gap between users and metadata descriptions of resources. We exemplify the advantage of the metadata-based search mechanism over the traditional keyword search with a proof-of-concept application.

Application of Data mining Technology

Abstract: It discusses application of data mining technology in Xinjiang Training Center of CNPC. The existing training management information system gathered lots of data, used data mining technology bases on these data, applied Microsoft SQL Server 2005 IDE and Microsoft Time Series as an example, created data mining model to mining data, predicted the abiliy of training Departments ,in order to provide useful informatns for Managers when they made decision of reasonable allocation training resources, finally summed up problems and solutions in the development process.

Utilizing metadata as a knowledge communication tool

Abstract: The modern enterprise environment is a collection of technical, functional, application, and data related assets loosely connected within a heterogeneous environment. Communicating the inventory, meaning, and eventual understanding of the knowledge held within the corporation can be a daunting task This work presents a detailed methodology and case study of building enterprise business intelligence from a multi-dimensional metadata framework. The framework includes structural, integration, and semantic metadata as well as the physical components required to deliver the functionality to the end user. The case study section will review a large telecommunications effort at communicating the knowledge of enterprise business intelligence.

The social space of metadata: perspectives of LIS academics and postgraduates on standards-based and socially constructed metadata approaches

Abstract: This article aims to contribute to the discussion on user-generated metadata. It presents the perspectives of eleven purposefully selected library and information science (LIS) academics and postgraduates on optimality of standards-based versus socially constructed metadata approaches and develops conceptual themes that emerged, which include the obsolescence of the Online Public Access Catalogue (OPAC) in relation to web search engines, the preference of users for searching versus browsing, and the proliferation of extant metadata standards resulting in interoperability challenges. This study also reveals the role ascribed to Web 2.0 and to semantic web technologies in libraries and the importance of enriching information objects with metadata that better conveys the various perspectives of users. Finally, the importance of underpinning metadata decisions with sound theoretical foundations is identified.

Direct access of language metadata

Abstract: Method and system for direct access of language metadata are disclosed. In an implementation, the method includes receiving commands from a user to modify language metadata of a programming language. The metadata is modified based on the command and the modified metadata is utilized as a feature in the programming language at runtime.
