Users and use cases

The last 10 years have seen a massive increase in the amounts of Open Access publications available in journals and institutional repositories. The open presence of large volumes of state-of-the-art knowledge online has the potential to provide huge savings and benefits in many fields. However, in order to fully leverage this knowledge, it is necessary to develop systems that (a) make it easy for users to discover, explore and access this knowledge at the level of individual resources, (b) explore and analyse this knowledge at the level of collections of resources and (c) provide infrastructure and access to raw data in order to lower the barriers to the research and development of systems and services on top of this knowledge. The CORE system is trying to address these issues by providing the necessary infrastructure. read more...

Yes, we can! – The CORE team organises a workshop at JCDL 2012 in Washington, DC

KMI and the European Library/Europeana jointly organised the 1st International Workshop on Mining Scientific Publications associated with JCDL 2012 – the most prestigious conference in the world of digital libraries. The workshop was attended by major players in the field including the National Library of Medicine, Library of Congress, CiteSeerX, Elsevier and British Library. Although Barack in the end didn’t come, the workshop was very successful, the only problem being the lack of chairs in the room. We (the workshop organisers – Petr Knoth, KMi; Zdenek Zdrahal, KMI and Andreas Juffinger, The European Library/Europeana) were motivated by the positive response of the community to the importance of issues researchers face when mining research publications to improve the way research is carried out and evaluated. read more...

Multithreading support in CORE

Over the last year, we have worked towards increasing the amount of metadata and full-text content in the aggregation and also on improving the updating frequency of the system. However, increasing the volume of content created also a higher demand on the efficiency of processing, maintaining and exposing the content. In the last three months, we have been optimising the CORE system to improve the parallelisation of processes the CORE system performs. These are namely: downloading and parsing large metadata description files, downloading pdf files from multiple sources, converting pdf files to text, extracting citation information from full-texts, recognising citation targets, discovering semantically related resources, indexing. All these processes have been optimised to allow a relatively even distribution of load across many parallel threads. This task was in our view very important and required significant development effort, but was definitely worth it! A typical CORE repository processing activity will be in our hardware environment distributed among 144 threads (24 processors each with 6 cores). The optimised system enables us to continue adding more repositories into the CORE aggregation and will also helps us to keep content in CORE fresh. read more...

How does CORE see my repository?

Since we first made CORE public, we’ve had a number of repository managers ask if we are harvesting their particular repository data. We’ve also sometimes come across issues harvesting content that we want to feedback to the repository manager (or other relevant staff). In order to be able to answer such questions, and to be transparent about what CORE is doing – what we have harvested, where we have encountered problems etc. we’ve now released a ‘Repository Analytics’ dashboard. read more...

New CORE design

CORE received as part of the release of version 0.7 a brand new design (http://core.kmi.open.ac.uk). The new design should be more user friendly. We have also added more information about CORE on the portal. We hope you will like it!

Best of both worlds

In the two previous blogs posts in this series (Finding fulltext and What does Google do?) I’ve described some of the challenges related to harvesting metadata and full text from institutional repositories. I’ve omitted some of the technical issues we’ve encountered (e.g. issues with OAI-PMH Resumption Tokens) as generally we’ve been able to work around these – although I may come back to these at some point in the future. Also worth a read is Nick Sheppard’s post on the UKCORR blog touching on some of these issues. read more...

CORE organises a workshop on Mining Scientific Publications at JCDL 2012

The CORE team is organising a workshop collocated with JCDL 2012, a major conference in the field of digital libraries. Our proposal to organise the 1st International Workshop on Mining Scientific Publications was accepted. The aim of the workshop is to bring together researchers, digital library developers and practitioners from government and industry to address the current challenges in the field of mining scientific publications and building the necessary infrastructure to support this. The topics of the workshop are directly related to the work carried out in both SreviceCORE and DiggiCORE projects and are available on the workshop website. read more...
