What I am saying is that there is huge scope for the scientific community to 'add value' to published scientific research in various ways. Adding value to the literature is made dramatically easier (and therefore are much more likely to happen) if the scientific research concerned can be downloaded in a structured XML form. And similarly, many of these forms of "added value" are both dramatically easier to implement, and dramatically more useful in practice, if they are not hobbled by the constraint that the original article/derivative versions may not be redistributed but can only be linked to. I can perhaps clarify what I mean by "added value" with an analogy. Take the new service Google Maps <http://maps.google.com> This is basically built from 2 resources: 1. Structured vector map data, along with zipcode/street address data, licensed by Google from NAVTEQ and TeleAtlas 2. Web page information harvested by Google robots (which happens to frequently include zip code and/or address information) Both of these resources have been available for years. Sites like www.mapquest.com use the very same NAVTEQ/TeleAtlas data, which is comprehensive, available in a standard structured format, and reasonably priced, given that mapping is a competitive market, and someone could always collect the map data themselves and undercut NAVTEQ if they grossly overcharged. Web page information is freely accessible to robot webcrawlers, and search engines have been making use of it since the mid-1990's. What Google has done is add value by using its technical know-how to build a powerful user interface which combines mapping and search technology, so that you can do a search for anything you like, in combination with a named location (e.g. swimming pools in Palo Alto,CA, or buddhist temples in Omaha, NE), and it will then show the closest relevant search results from across the web, dynamically overlaid onto a map at an appropriate level of magnification. This is a wonderful, innovative service, and it adds value to the underlying NAVTEQ data in a way that goes beyond what previous licensees of the data had managed to achieve. Now compare this to the situation with the scientific literature - imagine that you have an equivalently impressive idea for adding value to the scientific literature, how do you go about turning it into a reality? You can't easily license the data, because it is controlled by hundreds of different publishers, who you need to speak to separately. Those publishers have a monopoly on the research they have published, since you can't get those research articles from anyone else, and so they can charge you whatever they think they can get away with - there's no effective competition. And the publishers don't even store the data in a common structured format, so even if you succeed in getting funding and signing licensing deals, or rely on spidering their website, you don't end up with the structured information that you need to make the most effective use of the data. Structured information includes: reliably and consistently formatted bibliographic citation information, mathematical formulae, chemical structures, figure legends, author affiliation information etc etc. Sure, much of this can be partially reverse-engineered from an unstructured version of the document, but this process is complex, error-prone and a major unnecessary hurdle to re-use. The more hurdles there are, the less chance there is that any given idea for adding value will see the light of day. It's not simply a question of whether something is possible - we need to be making it *easy* to add value to the data. The irony in the comparison with NAVTEQ is that NAVTEQ spends a lot of money to collect the data and yet this proprietary data ends up being far more available for re-use than the traditional scientific literature, even though the scientific literature is freely contributed by authors, who have have nothing to gain from it being restrictively licensed, and everything to gain from wide re-use. It is a fantastic achievement on the part of traditional publishers that they have got away with this for so long! So anyway, here is a very partial list giving some specific examples of how value can be added to scientific research articles. Stevan, I know that you will object that some of these things could theoretically be achieved without access to the XML, and without rights to redistribution, but my point is not that these things are *impossible* in the absence of structured XML and rights for reuse/redistribution, but that all are made immeasurably *easier* if freely re-distributable structured data is available. The practical result of this is that making the re-usable and re-distributable XML available has an immensely stimulating effect on innovation. * Digital archives The University of Potsdam is one of several institutions which maintains a comprehensive local mirror of BioMed Central's open access content: http://bmc.ub.uni-potsdam.de/ Similarly, OhioLink integrates copies of all BioMed Central open access research articles into their local archive. http://www.ohiolink.edu/ * Image mining/reuse Several groups are working with BioMed Central's collection of open access figures. One group plans to use the images and their legends as part of a free searchable collection of biological images. Another is developing image processing techniques to extract useful information from vector-based images automatically. * Text mining Several different text mining groups are experimenting with applying advanced information retrieval techniques to BioMed Central's XML data. The UK e-Science program recently created a National Centre for Text Mining: http://www.cse.salford.ac.uk/nactem/ The following article by the directors of the centre is not a bad place to start if you want to know what text mining is, and why it is important: http://www.ariadne.ac.uk/issue42/ananiadou/ At the simple end of the text mining spectrum, consider the Collexis concept-based indexing/search tool, a basic version of which is used by the e-BioSci prototype. Collexis's concept-based search, amongst other things, is multi-lingual - it allows you to use another language (e.g. French, or German) to query an English language corpus of documents (and vice versa). http://www.collexis.com http://prototype.e-biosci.com/search/query * Antbase http://antbase.org/ brings together taxonomic descriptions across thousands of ant species into a single database. As Donat Agosti has pointed out in this forum, Antbase is severely hampered by the restrictions on re-use and re-distribution which cover much of the taxonomic literature. It would also benefit greatly from the availability of structured XML for research articles, especially if that XML were to include a standardized representation of taxonomic information. * PubMed's Bookshelf http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Books This NCBI system adds value to scientific text books, by slicing them up into fragments, and then using textual analysis to associate those fragments with they key terms that they relate to. As a result of this when searching PubMed and viewing an abstract, you can click the 'Books' link to highlight phrases for which textbook links are available, to clarify the concept concerned. For an example, see: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&list_ui ds=15450118&dopt=Books This whole system relies on having structured XML data from the publisher. It uses textbooks that have been made available with the consent of the publisher, so it is not directly a case of the reuse of open access research. But what it *is*, is a demonstration of how, if you are allowed access to the XML, and given the right to redistribute the content, you can add a huge amount of value. * Specialist tools for searching particular types of structured information BioMed Central articles will soon contain embedded MathML versions of all mathematical formulae. How best to search this type of content is an active area of research: http://www.ima.umn.edu/complex/spring/searching.html The availability of open access research articles containing embedded MathML will mean that researchers will be able to test out their math-searching techniques on real world data, and make available MathML-enhanced search engines. [The same will apply for other emerging domain-specific dialects of XML that can be embedded within articles - e.g. CML for Chemistry] * Biological database linking, as done by PubMed Central Since PubMed Central holds a central collection of Open Access content in a standard XML format,it is able to add a huge amount of value through linking against the NCBI's biological databases. For example, all mentions of small molecules (referred to by any common alias) within the text of the article, are identified and linked to the relevant compounds in NCBI's small molecule database (PubChem), allowing the user to then find similar compounds, and to follow the links to find other articles which relate to those similar compounds. e.g. this article on COX-1 and COX-2 inhibitors http://www.pubmedcentral.gov/articlerender.fcgi?tool=pmcentrez&artid=408457 links to the following 'substances' http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pmc&cmd=Display&from_uid=40 8457&dopt=pmc_pcsubstance Again, I'm not saying that all the above is *impossible* with self-archived material in unstructured form. I am saying is that it is all dramatically easier if the final official XML version is open access and redistributable. The explicit right of authors to self-archive their manuscript, and "free access but only on the publisher's website" are certainly incremental steps forward, and should be welcomed. But there's a whole lot more that will be achievable once the bulk of the scientific literature is fully open access in the Bethesda/Berlin/Budapest sense (i.e. available in a structured form, and fully redistributable). > (4) Moreover, both these publishers are both *green*, which > means that the > author can self-archive his own final, revised, peer-reviewed draft as > a supplement on his own website, including any enhancements > (e.g., XML) > that he may wish to add to it. > http://romeo.eprints.org/publishers.html > http://archives.eprints.org/ But in the long term, is it really the best use of resources invested by the funder/employer for researchers to spend their time self-archiving their research, identifying any significant changes which happened during post-acceptance proofing and copy-editing, reconciling their various versions, coordinating XML markup etc? Surely this can far more efficiently be taken care of as an inherent part of the publishing process, rather than being tacked on the end?
