Efficient, automatic web resource harvesting

Michael L. Nelson, Joan A. Smith, Ignacio Garcia del Campo
2006 Proceedings of the eighth ACM international workshop on Web information and data management - WIDM '06  
There are two problems associated with conventional web crawling techniques: a crawler cannot know if all resources at a non-trivial web site have been discovered and crawled ("the counting problem") and  ...  We present the Apache module "mod oai", which can be used to address the counting problem by listing all valid URIs at a web server and efficiently discovering updates and additions on subsequent crawls  ...  CONCLUSIONS mod oai is a demonstration of combining complex object metadata formats with OAI-PMH for efficient web resource harvesting.  ...

Integration of Non-OAI Resources for Federated Searching in DLIST, an Eprints Repository

Anita Coleman, Paul Bracke, S. Karthik
2004 D-Lib Magazine  
The Open Archives Initiative Protocol for Metadata Harvesting (OAIPMH) is designed to facilitate searches across OAIcompliant databases.  ...  Software such as Arc allow service providers to offer federated searching of multiple, OAIcompliant resources. The majority of webaccessible information resources, however, are not OAIcompliant.  ...  It must be possible to schedule harvesting of nonOAI resources regularly and automatically. 3. The process developed must be transferable.  ...

Evaluation of Semi-Automatic Metadata Generation Tools: A Survey of the Current State of the Art

Jung-ran Park, Andrew Brenza
2015 Information Technology and Libraries  
One promising approach to managing the ever--increasing amount of information is with semi-automatic metadata generation tools. Semi--automatic metadata generation tools Jung--ran Park  ...  The greatest area of difficulty lies in the fact that the piecemeal development of most semi--automatic generation tools only addresses part of the issue of semi--automatic metadata generation, providing  ...  The harvested metadata can be stored in a central repository for future resource retrieval.  ...

Towards an Open Learning Infrastructure for Open Educational Resources: Abundance as a Platform for Innovation [chapter]

Erik Duval, Katrien Verbert, Joris Klerkx
2011 Lecture Notes in Computer Science  
By removing friction between people and resources, we can leverage the long tail of learning resources, so that the abundance of learning resources will act as a platform for innovation.  ...  This paper explains how we have contributed to the development of an open learning infrastructure that manages and makes available Open Educational Resources.  ...  Typically, for those targets, it does not make sense to harvest all of their resources.  ...

AUTOMATING MAPPING PRODUCTION FOR THE ENTERPRISE: FROM CONTRACT TO DELIVERY

R. Uebbing, C. Xie, B. Beshah, J. Welter
2012 The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences  
But the data volume alone is not the only barrier for an efficient production work flow.  ...  Ideally, users will interact with the system to retrieve a specific project status and summaries while the work flow processes are triggered automatically by modeling their dependencies.  ...  The different harvesters in return use metadata harvesters registered in the system to provided metadata from diverse sources for each resource being harvested into the catalogue.  ...

Towards Semantic Web-Based Information Retrieval to solve Information Overload in an Applied Gaming Ecosystem

Philippe Tamla
2019 Bulletin of IEEE Technical Committee on Digital Libraries  
Others have used Semantic Web Technologies to enrich web resources with additional facts and meaning, but have let the system (and not the end-user) decide about the relevance of the search result failing  ...  To solve IO, existing contributors have used complicated mechanisms that index the Web and harvest large piles of documents to detect relevant materials.  ...  Automated knowledge extraction can help tackle IO because it can retrieve useful knowledge (in form of named entities) from naturally written texts automatically, which can be used for efficiently searching  ...

Managing Open Educational Resources on the Web of Data

Gilbert Paquette, Alexis Miara
2014 International Journal of Advanced Computer Science and Applications  
First, within MOOCs, all (or at least most) resources must be open and available on the Web through URIs, including the MOOCs themselves.  ...  In the last few years, the international work on Massive Open On-line Courses (MOOCS) underlined new needs for open educational resources (OER) management within the context of the Web of Data.  ...  Most of the time, however, the metadata records will be harvested automatically by either an OAI-PMH Harvester or a HTML Spider.  ...
