Emerging non-volatile memory (NVM) technologies provide opportunities to improve the performance of key-value databases (KVDBs) by deploying database on NVM. However, existing in-memory KVDBs cannot fully exploit the advantages of NVM. They process data on in-memory database and store an image on persistent storage via an underlying file system. The performance of database operations is degraded by...
Building upon a collection with functionality for discovery and analysis has been described by Lynch as a `layered' approach to digital libraries. Meanwhile, as digital corpora have grown in size, their analysis is necessarily supplemented by automated application of computational methods, which can create layers of information as intricate and complex as those within the content itself. This combination...
Tujia brocade (Xi lan ka pu) is a kind of traditional handcraft brocade which was listed in the first batch of non-material cultural heritage of China. It has become a popular trend to promote non-material cultural heritage with digital technology. Personalization recommendation for Tujia brocade culture resources could push new knowledge and something the user interested in, which could improve the...
The Nevada Research Data Center (NRDC) joined up with DataONE by becoming a Member Node to help with their goal of preserving and sharing scientific data. The NRDC is an NSF funded data management center for several climate based research groups across Nevada. DataONE is a collaboration that seeks to conserve scientific data and make researching global ecological issues easier. We brought our Member...
Palm-leaf manuscripts are a unique medium that serve as a repository of knowledge from across a few centuries. Digitization is an essential process to preserve this knowledge and provide access to users. Due to their unique nature, palm-leaf manuscripts pose some specific challenges. This paper highlights such challenges identified during the course of implementation at SCSVMV University Palm Leaf...
Text Extraction plays an important role in finding valuable information. As a result of rapid growth of available multimedia documents on web and increasing requirement for information, identification, indexing and retrieval, several research have been done on text extraction. Here, a methodology to build a system for text extraction has been presented that is designed to provide support to the applications...
The metadata system is introduced into the design of coal mine equipment management system, use SQL Server2005 to build Coal mining equipment management information element database and other databases, and develop all the modules by VC 6.0, through ADO (ActiveX Data Objects) to store and transfer data. The application of the system is able to help regulate the management of coal mining enterprise,...
Building digital library applications is often a search for an applicable and adequate data or document model as well as for software tools which meets the requirements. Especially in digital archives, there are several data and document models to be considered. Unfortunately, there is no one-size-fits-all document model or system. For each application, the requirements and properties of a project...
Digital preservation has now become a key activity in every library and information center due to proliferation of Information and Communication Technologies (ICT) and advancement of Internet technologies. The availability of Open Source Software, training at desired time and market demand has revolutionized the creation of digital libraries. Digitization and preservation of readily available resources...
Learning registry is a network for sharing metadata and paradata about the learning resources. We created experimentally a website that visualizes these data and provides basic interactions with the learning registry, such as viewing the resources, searching, rating, and posting of specific resources to the network. These experiments serve for testing the offered technologies and for the specification...
Often in a research community there are several different metadata standards used to describe the same type of objects. In this paper we explore using an RDF/XML (Resource Description Framework) framework to address this issue, and create a flexible, reusable solution that can adapt to new metadata standards. We create a semantic framework that contains multiple metadata views of the objects that...
The purpose for integration system is to provide a unified, global view to the user over various heterogeneous sources. To answer user queries, a data integration system employs a set of semantic mapping between and mediated schema(global schema) and schemas of data sources (local schema). Such data integration raises main challenging issue: (1) Scheme creations and (2) Schema mappings. In order to...
This article presents a concept model, and the associated tool to help advanced learners to find adapted bibliography. The purpose is the use of an IT representation as educational research software for newcomers in research. We use an ontology based on the ACM's Computing Classification System in order to find scientific articles directly related to the new researcher's domain without any formal...
The paper explores the new model of Information resource sharing of Personal Digital Library by using such methods as the systems analysis and design and the simulation. Through the technology such as the P2P, metadata and database, it aims to construct the PDL resource sharing platform to implement the effective information resource sharing of PDL in the certain sharing scope such as academic society,...
