With this aim in mind, many recent efforts have attempted to supplement increasing membership with more advanced services, such as searching and browsing that span multiple collections of ETDs. France, Eskinder Sahle, Amjad M.
All that is necessary is to provide methods that follow the API of generating a weight from an object description and, thence, a weighted set of objects. Therefore, in the interim, semantic heterogeneity is a problem that has to be dealt with. Besides being thus tailored to the typical information-seeking behavior of researchers, the interface also has multilingual capabilities.
The OAI protocol is a request-response protocol layered over HTTP that allows one computer to collect metadata incrementally over time from another computer - this is commonly known as harvesting. Nodes in the MARIAN information network can be simple atomic or scalar objects, as in the semi-structured model [ Abiteboul, ], but they also can be complex information objects.
This portal provides users with a simple and intuitive interface to search and browse through the merged collection of theses and dissertations. Current NDLTD Research Efforts NDLTD has a strong commitment to advance the state of the art in electronic publishing and digital library technologies and services, in connection with its core activities supporting graduate education and sharing of knowledge.
Posted Jul 2, OATD currently indexes 3, theses and dissertations. Virtua ILS, their flagship product, is an integrated library automation system specifically designed to cater to the differing needs of librarians in different contexts. Most ETDs are made up of structures of text in a particular language.
Additional research efforts include advanced search mechanisms, semantic interoperability, the design and development of multi- and cross-lingual search systems, and software modules that support the development of higher-level services to aid researchers in seeking relevant ETDs.
Many theses are available electronically, at no charge, directly from the publishing institution. Serving Users in Many Languages: Two excellent resources are: Virtua supports multiple modes of data entry, converting all input data into the standard USMARC format that is familiar to many librarians and archivists.
About 50, are online. For instance, MARIAN treats title text as a special sort of natural language sequence, with various rules for capitalization, punctuation, and sentence formation, but treats names of persons as sequences of atomic strings. These uses interact; while the simple construct of synthetic superclasses with weighted subclasses cannot handle every situation, we have found it strikingly effective.
France, Kaushal Dalal, and Edward A. Digital information objects and connecting links are organized into object-oriented classes, each supporting indexing, retrieval, and presentation methods.
It also provides information on the online availability of electronic theses in the library and information science through centrally-maintained digital repositories which not only ensure easy access and archiving of doctoral theses but will also help in raising the standard and quality of research.
This system distributes a query to multiple sites and then gathers the result pages into a cache for browsing. Current research on translation is based on the work of Akira Maeda and the NAIST Multilingual group [ Maeda, ], using co-occurrence statistics to scale and combine different translations.
The responses are XML documents whose structures are defined precisely using the XML Schema Description [ Fallside, ] language, with protocol tags designed to support the operation of the protocol and container tags that encapsulate individual record or archive-level metadata.The NDLTD Union Catalog project focused on theses metadata via the Protocol for Metadata Harvesting (OAI-PMH).
It was a lightweight protocol for moving or sharing metadata that allowed synchronization of loosely coupled databases and mandates XML Dublin Core as the default metadata format. NDLTD (Networked Digital Library of Theses and Dissertations) - Free - The Networked Digital Library of Theses and Dissertations (NDLTD) is an international organization dedicated to promoting the adoption, creation, use, dissemination, and preservation of electronic theses and dissertations (ETDs).
