Public Storehouse of Knowledge

• Multiple open digital archives, holding all the world’s knowledge. A single logical universal archive, created by dynamic federation of all public archives.

• Contains everything: archive holds grey literature (publicly deposited) and gold literature (refereed articles).

• No barriers to access. Knowledge is freely available to anyone, any time, anywhere.

• Access to information and knowledge correlates to society’s quality of life.

Harvester(NeoRef)

NeoRef Model • All content and metadata are author contributed to a

public OAI archive (author retains ownership).• OAI archives have automated or manual moderator to

filter out “junk”.• Everything--articles, reviews, comments, indexings,

images, genetic sequences, etc., are stored as digital content items on archive using the same mechanism.

• All materials universally available via search engines that harvest metadata from OAI archives.

• Retrieval is through Google like one stop shopping search interface, with dynamic filtering based on metadata and reviews to limit hits to manageable number to review.

Scholarly Communications Process: What’s Captured Today

Journal Final Revision

V6

Only one version is captured, and the same community then pays to buy back access to article

Change the Process!

• Think of scholarly communication as continuous process instead of single product (journal publication).

• Capture significant changes/versions of a work.• Include all criticisms and comments about work (all

stages). • Support normal scholarly discourse, including authors

responses as well as others comments. • Add reviewer’s quantitative rating of material to allow

better filtering based on absolute quality metric during retrieval.

• Add machine (automated) reviews.

Copyproofing

Selected Technical Challenges

• Self Contribution (SILS ETDs)– Author indexed– Author supplied metadata (Dublin Core) as part of

authoring process (i.e. not separate after the fact).– Automatic extraction of metadata from document.– Archive file(s) must be in standard open format

NeoRef: PDF/A with DC elements in tags for automatic extraction of metadata. Expect migration to XML as we continue to divorce content from presentation.

Challenges

• Searching– DC metadata to allow coarse discovery.– Specialized searching within domain after locating material

(based on metadata field indicating appropriate search interface).

– Interactive searching to allow refinement to most desirable set within a few seconds. Use rankings and reviews (Facultyof1000), citations (CiteSeer), usage (web page hits) to help filter search

– Google searching on full text (covers all materials, but generates large number of hits, lower specificity).

– Automated agents to bring material of interest to your attention• Example: article scores > 7.0, refereed, citation

count above 10, type=research article, search terms = schizophrenia, geneX)

Challenges

• Knowledge Representation– Extend DC to include “concepts” and “claims”

(ScholOnto), with ontology to define framework of relationships between concepts; this allows a higher level of searching compared to simple indexing.

– Make OAI and DC representation more robust by always supporting DOI to uniquely identify materials.

– Support unique identification of authors as well.– Making all content items submitted permanent– Use DC fields to link related items, new version of

paper to old version.

Challenges

• Rights Administration– Support mechanisms to allow authors to set

permissions as they desire, and enforce this.

– NeoRef supports Creative Commons through DC rights element.

– OAI recent supported rights administration using Creative Commons (and looking at how to handle collections etc where DC rights element may be insufficient).

The End

What about Peer Review?

The ALPSP survey was intended to discover the views of academics, both as authors and as readers. Some 14,000 scholars were contacted across all disciplines and all parts of the world, and with almost 9% responding.

and Professional Society Publishers, 2002).http://www.alpsp.org/pub5.htm

Peer Review Options• Review based

– Expert peer review (status quo)– Certified expert peer review– Open peer review BMJ, BioMed– Open public comment review psycprints– Computer peer review

• Community – Respected or similar people rankings– Community rankings (Amazon for books)

• Coarse Categorization– Multi-tier (grey/gold, or UCB’s 4 level journal offering)– Moderator (current arXiv)– No review (old arXiv, problematic)

• Usage based– Citation-based (CiteSeer)– Usage counts (CiteSeer) Example– Quantity of discussion threads (email/newsgroups/weblogs)

Big Picture Changes

• What is worth paying for?– Quality review (Faculty of 1000)– Proofing, citation linking, professional presentation

(CiteSeer, Cite-base)– Marketing – Archival (JStor)

• Who hosts material?– Society (arXiv)– Commerical Publishers (Elesiever,BioMedCentral)– University Library (MIT DSpace)

How Peer Review might work…

• Author submits article to her institution’s open archive (DOI uncch:sils/0007548.pdf).

• Author “submits” to journal EMEDICINE by providing DOI of article.

• Journal Editor schedules two reviewers. Reviewers review article, and submit their reviews (cornell:0191.pdf, ucb:0084.pdf).

• Author revises, and places revised article (DOI uncch:sils/0007957.pdf) on archive, and submits this final version to EMEDICINE.

• Journal submits review (EMED:0023424.pdf) which is final statement from journal (editor), and indicates acceptance of uncch:sils/0007957.pdf as EMED article).

Survey (Project Romeo)

• Authors want quick and convenient dissemination of their work– Free access to others papers– Not overly concerned (or aware) of copyright

issues unless it stops them from freely distributing their work or accessing others.

Survey (Zhang 1999)

• Important to authors are– Permanence and Quality of electronically

survey archived resources– Better (faster, more accurate) searching

capabilities, i.e. using metadata instead of just search engines.

Survey (Rowland)

• 16% said that the referees would no longer be anonymous

• 27% said that traditional peer review would be supplemented by post-publication commentary

• 45% expected to see some changes in the peer-review system within the next five years

Extra Material….

Additional Challenges

• Archive Hosting– Off the shelf computer system with lots of disk

space and public domain archiving application (DSpace, Eprints).

– Who maintains the material? {Library (MIT DSpace), Grad School, University (California), Publisher (PLoS, BioMedCentral), Society (arXiv)}

– Where are comments and reviews held (after the fact content items that reference original)?

Challenges

• Make content universally available– Export OAI items so they can be harvested– Have public domain quality harvesters that

support quick and simple searching (i.e. Google for metadata).

Challenges

• Peer Review– Make more public. Make available comments

on articles.– Add quantitative scoring as well as qualitative.

General Review Model Parallels

• In general, you have sample (material) which is judged/scored quantitatively and qualitatively by an identified observer with respect to some standard.

NeoRef for Movies, Products,…

• The same process used by NeoRef to support Scholarly Communication could be used for most any communication of informaiton purpose. All that is required is storage of Digital Content Items, and linking of reviews, comments, etc to them.

• DocSouth: self cataloged and indexed items are Grey; librarian/archivist cataloged and indexed items are Gold.

• Movies: Grey is everyone’s reviews; Gold is Siskel and Ebert reviews.

• Consumer Products: product reviews by Consumer Reports (gold), user reviews (grey).
