Code4Lib2012 talk proposals are now on the wiki. This year there are 72 proposals for 20-25 slots. I pulled out the talks mentioning semantics (linked data, semantic web, microdata, RDF) for my own convenience (and maybe yours).

Property Graphs And TinkerPop Applications in Digital Libraries

• Brian Tingle, California Digital Library

TinkerPop is an open source software development group focusing on technologies in the graph database space.
This talk will provide a general introduction to the TinkerPop Graph Stack and the property graph model is uses. The introduction will include code examples and explanations of the property graph models used by the Social Networks in Archival Context project and show how the historical social graph is exposed as a JSON/REST API implemented by a TinkerPop rexster Kibble that contains the application’s graph theory logic. Other graph database applications possible with TinkerPop such as RDF support, and citation analysis will also be discussed.

HTML5 Microdata and Schema.org

• Jason Ronallo, North Carolina State University Libraries

When the big search engines announced support for HTML5 microdata and the schema.org vocabularies, the balance of power for semantic markup in HTML shifted.

• What is microdata?
• Where does microdata fit with regards to other approaches like RDFa and microformats?
• Where do libraries stand in the worldview of Schema.org and what can they do about it?
• How can implementing microdata and schema.org optimize your sites for search engines?
• What tools are available?

“Linked-Data-Ready” Software for Libraries

• Jennifer Bowen, University of Rochester River Campus Libraries

Linked data is poised to replace MARC as the basis for the new library bibliographic framework. For libraries to benefit from linked data, they must learn about it, experiment with it, demonstrate its usefulness, and take a leadership role in its deployment.

The eXtensible Catalog Organization (XCO) offers open-source software for libraries that is “linked-data-ready.” XC software prepares MARC and Dublin Core metadata for exposure to the semantic web, incorporating FRBR Group 1 entities and registered vocabularies for RDA elements and roles. This presentation will include a software demonstration, proposed software architecture for creation and management of linked data, a vision for how libraries can migrate from MARC to linked data, and an update on XCO progress toward linked data goals.

Your Catalog in Linked Data

• Tom Johnson, Oregon State University Libraries

Linked Library Data activity over the last year has seen bibliographic data sets and vocabularies proliferating from traditional library
sources. We’ve reached a point where regular libraries don’t have to go it alone to be on the Semantic Web. There is a quickly growing pool of things we can actually ”link to”, and everyone’s existing data can be immediately enriched by participating.

This is a quick and dirty road to getting your catalog onto the Linked Data web. The talk will take you from start to finish, using Free Software tools to establish a namespace, put up a SPARQL endpoint, make a simple data model, convert MARC records to RDF, and link the results to major existing data sets (skipping conveniently over pesky processing time). A small amount of “why linked data?” content will be covered, but the primary goal is to leave you able to reproduce the process and start linking your catalog into the web of data. Appropriate documentation will be on the web.

NoSQL Bibliographic Records: Implementing a Native FRBR Datastore with Redis

• Jeremy Nelson, Colorado College, jeremy.nelson@coloradocollege.edu

In October, the Library of Congress issued a news release, “A Bibliographic Framework for the Digital Age” outlining a list of requirements for a New Bibliographic Framework Environment. Responding to this challenge, this talk will demonstrate a Redis (http://redis.io) FRBR datastore proof-of-concept that, with a lightweight python-based interface, can meet these requirements.

Because FRBR is an Entity-Relationship model; it is easily implemented as key-value within the primitive data structures provided by Redis. Redis’ flexibility makes it easy to associate arbitrary metadata and vocabularies, like MARC, METS, VRA or MODS, with FRBR entities and inter-operate with legacy and emerging standards and practices like RDA Vocabularies and LinkedData.

ALL TEH METADATAS! or How we use RDF to keep all of the digital object metadata formats thrown at us.

• Declan Fleming, University of California, San Diego

What’s the right metadata standard to use for a digital repository? There isn’t just one standard that fits documents, videos, newspapers, audio files, local data, etc. And there is no standard to rule them all. So what do you do? At UC San Diego Libraries, we went down a conceptual level and attempted to hold every piece of metadata and give each holding place some context, hopefully in a common namespace. RDF has proven to be the ideal solution, and allows us to work with MODS, PREMIS, MIX, and just about anything else we’ve tried. It also opens up the potential for data re-use and authority control as other metadata owners start thinking about and expressing their data in the same way. I’ll talk about our workflow which takes metadata from a stew of various sources (CSV dumps, spreadsheet data of varying richness, MARC data, and MODS data), normalizes them into METS by our Metadata Specialists who create an assembly plan, and then ingests them into our digital asset management system. The result is a beautiful graph of RDF triples with metadata poised to be expressed as HTML, RSS, METS, XML, and opens linked data possibilities that we are just starting to explore.

UDFR: Building a Registry using Open-Source Semantic Software

• Stephen Abrams, Associate Director, UC3, California Digital Library
• Lisa Dawn Colvin, UDFR Project Manager, California Digital Library

Fundamental to effective long-term preservation analysis, planning, and intervention is the deep understanding of the diverse digital formats used to represent content. The Unified Digital Format Registry project (UDFR, https://bitbucket.org/udfr/main/wiki/Home) will provide an open source platform for an online, semantically-enabled registry of significant format representation information.

We will give an introduction to the UDFR tool and its use within a preservation process.

We will also discuss our experiences of integrating disparate data sources and models into RDF: describing our iterative data modeling process and decisions around integrating vocabularies, data sources and provenance representation.

Finally, we will share how we extended an existing open-source semantic wiki tool, OntoWiki, to create the registry.

saveMLAK: How Librarians, Curators, Archivists and Library Engineers Work Together with Semantic MediaWiki after the Great Earthquake of Japan

• Yuka Egusa, Senior Researcher of National Institute of Educational Policy Research
• Makoto Okamoto, Chief Editor of Academic Resource Guide (ARG)

In March 11th 2011, the biggest earthquake and tsunami in the history attacked a large area of northern east region of Japan. A lot of people have worked together to save people in the area. For library community, a wiki named "savelibrary" was launched for sharing information on damages and rescues on the next day of the earthquake. Later then people from museum curators, archivists and community learning centers started similar projects. In April we joined to a project "saveMLAK", and launched a wiki site using Semantic MediaWiki under http://savemlak.jp/.

As of November 2011, information on over 13,000 cultural organizations are posted on the site by 269 contributors since the launch. The gathered information are organized along with Wiki categories of each type of facilities such library, museum, school, etc. We have held eight edit-a-thons to encourage people to contribute to the wiki.

We will report our activity, how the libraries and museums were damaged and have been recovered with lots of efforts, and how we can do a new style of collaboration with MLAK community, Wiki and other voluntary communities at the crisis.

I got to talking with a mathematician friend about citation management. We came to the conclusion that “manage PDFs” is my primary goal while “get out good citations” is his primary goal. I thought it would interesting to look at his requirements.

His ideal program would

1. Organize the PDFs (Papers does this, when it doesn’t botch the author names and the title) preferably in the file system, so I can use Dropbox
2. Get BibTeX entires from MathSciNet, ACM, etc. EXACTLY AS THEY ARE
3. Have some decent way to organize notes by “project” or something

He doesn’t care about:

1. Typing \cite
2. A “unified” bibliographic database
3. Social bibliographies (though I am not against them; it is just not a burning issue)

He says:

I guess the point is that, if I am writing something and I know I want to cite it, and I know there is a “official” BibTeX for it, I just need a way to get that more quickly than:

1. Type the URL
2. Click on “Proxy this” in my bookmarks bar
3. Search for the paper
4. Copy/paste the BibTeX
5. Edit the cite key to something mnemonic

He followed up with an example of the “awful” awful, lossy markup Papers produces which loses information including the ISSN and DOI; he prefers the minimalist BibTeX. (oops!; he adds “I understated how bad papers is. The real papers entry (top) not only has screwy names, but junk instead of the full journal name. The papers cite key is meaningless noise too (but mathscinet is meaningful noise).”) To get around this, he does the same search/download “a million times”.

AMS Papers2 BibTeX:
@article{AR78,
author = {L Asimow and B Roth},
journal = {Trans. Amer. Math. Soc.},
title = {The rigidity of graphs},
pages = {279--289},
volume = {245},
year = {1978},
}

Papers' The AMS version of the same BibTeX:
@article {AR78,
    AUTHOR = {Asimow, L. and Roth, B.},
     TITLE = {The rigidity of graphs},
   JOURNAL = {Trans. Amer. Math. Soc.},
  FJOURNAL = {Transactions of the American Mathematical Society},
    VOLUME = {245},
      YEAR = {1978},
     PAGES = {279--289},
      ISSN = {0002-9947},
     CODEN = {TAMTAM},
   MRCLASS = {57M15 (05C10 52A40 53B50 73K05)},
  MRNUMBER = {511410 (80i:57004a)},
MRREVIEWER = {G. Laman},
       DOI = {10.2307/1998867},
       URL = {http://dx.doi.org/10.2307/1998867},
}

I’ve just discovered that BibDesk‘s¹ ‘minimize’ does what he wants: its has output is quite close to the AMS Papers2 version:

@article{AR78,
	Author = {Asimow, L. and Roth, B.},
	Journal = {Trans. Amer. Math. Soc.},
	Pages = {279--289},
	Title = {The rigidity of graphs},
	Volume = {245},
	Year = {1978}}

I’d still like to understand the impact the non-minimal BibTeX is having; could be bad citation styles are causing part of the problem.

While we have different needs for citation management, we’re both annoyed by the default filenames many publishers use – like fulltext.pdf and sdarticle.pdf. But I’ll tolerate these, as long as I can get to it from a database index with a nice frontend.

We of course moved on to discussing how research needs an iTunes or, as Geoff Bilder has called it, an iPapers.

This blog post brought to you by Google chat and the number 3.

1. See also A short review of BibDesk from MacResearch

Today I’ve been testing out Sente, on the theory that it might help me organize the PDFs I’m annotating on my iPad.

The desktop application is geared to Mac users who really care about bibliographies, with several fantastic features, including

• Unlike their competitors (e.g. Mendeley, Zotero), they appear to offer free unlimited synchronization of your reference library: the only limitation is that files larger than 20MB won’t be synched.
• Sophisticated import from the underlying file structures of many different reference managers (EndNote, Bookends, Mendeley, Papers, and Zotero)
• Customizable multicolored search called hotwords to help draw your eye to the keywords you persistently care about (watch the hotwords video, it’ll make sense).

I like Sente’s statuses; read/unread and Recently Modified and Recently Added are automatically tracked, and you can rate items. I especially like the workflow statuses, which match some of my common tasks:

• Get Full Text
• Discuss Further
• Cite
• Do Not Cite

“Sort by citation” is surprisingly illuminating: I didn’t realize how many papers from “Discourse Studies” I’d been looking at recently.

Another great feature that could be easily and fruitfully added to most other bibliographic managers: title case and exact case lists (I am *so* sick of seeing lowercased ‘wikipedia’ in bibliographies!), which you can very easily customize.
Sente also has a journal dictionary: You can assign the abbreviations and ISSNs (authority control, yippee!)!

Their visual display could use an update (thankfully it’s on the way) and I find their icons confusing (maybe ‘pencil’ for ‘note’ is sensible, but what in the world about ‘four dots in a diamond shape’ says ‘abstract’ to you?)

I tested the Zotero import. As I wrote Sente’s developers, there are some issues:

In testing it out on my large (5000+ item) Zotero library I see that:

1. HTML attachments are not copied into the Sente library
2. Image attachments are not copied into the Sente library
3. Text note attachments are not copied into the Sente library
4. Subcollections are not preserved

Since then, I’ve noticed that the keywords don’t get imported. Further, the date added and “date modified” fields are not preserved, but instead now reflect the import date and time (as I noted on twitter). But I do like their duplicate detection. Along with promising to consolidate matched items, they provide a report about the discarded matches. For instance:

Rule “DOI rule” flagged these two references as possible duplicates:
Vilar, P., & Žumer, M. (2008). Perceptions and importance of user friendliness of IR systems according to users’ individual characteristics and academic discipline. Journal of the American Society for Information Science & Technology, 59(12), 1995-2007. doi:Article
Quick-Response Barcodes. (2008). Library Technology Reports, 44(5), 46-47. doi:Article
However, the match was rejected because the references differ in: Article Title, pages, Publication Title, URL, Volume, Issue.

I have played briefly with the Sente’s free iPad viewer, but not yet with their paid ($19.99) app which allows annotation. Based on reviews (why no permalinks, Apple?), “Export seems to be an option but crucially, import is not.” However, if Sente’s annotation is enough, there’s hope, since documentation of the Sync functionality already in the current (6.2) version the description of Sync for the planned 6.5 release (via this) is *very* promising: “As you read a PDF on your iPad on the bus ride home, highlighting passages and taking notes, the highlighting and notes appear in all copies by the time you arrive home.”

By Sente user standards, I am far from a power user: the biggest databases seem to be about 10 times mine. This could be an improvement from Zotero, where my library speed can’t quite keep up some days. I’d be *very* interested to hear from enthusiastic Sente users. Switching seems quite feasible, and probably worth checking out their iPad app.

The main obvious concerns I have are about notetaking and portability. Notetaking of offline/non-fulltext items is important but doesn’t seem to have been a particular focus of development. Portability is incredibly important: I need to ensure that export (and ideally import) brings along files and notes as well as PDFs.

I’ve been thinking of direct, in-file PDF annotation as the best possible way to ensure that my annotations outlive my reference manager. Should I rethink that? So far (according to their draft manual as above): “Highlighting created in Sente 6.2 is not stored in the PDF itself — it is stored in the library database. This change has several very positive effects, notably on syncing.” Let me know what you think in the comments!

We’ve extended the STLR 2011 deadline due to several requests; submissions are now due May 8th.

JCDL workshops are split over two half-days, and we are lucky enough to have *two* keynote speakers: Bernhard Haslhofer of the University of Vienna and Cathy Marshall of Microsoft Research.

CALL FOR PARTICIPATION
The 1st Workshop on Semantic Web Technologies for Libraries and Readers

STLR 2011

June 16 (PM) & 17 (AM) 2011

http://stlr2011.weebly.com/
Co-located with the ACM/IEEE Joint Conference on Digital Libraries (JCDL) 2011 Ottawa, Canada

While Semantic Web technologies are successfully being applied to library catalogs and digital libraries, the semantic enhancement of books and other electronic media is ripe for further exploration. Connections between envisioned and emerging scholarly objects (which are doubtless social and semantic) and the digital libraries in which these items will be housed, encountered, and explored have yet to be made and implemented. Likewise, mobile reading brings new opportunities for personalized, context-aware interactions between reader and material, enriched by information such as location, time of day and access history.

This full-day workshop, motivated by the idea that reading is mobile, interactive, social, and material, will be focused on semantically enhancing electronic media as well as on the mobile and social aspects of the Semantic Web for electronic media, libraries and their users. It aims to bring together practitioners and developers involved in semantically enhancing electronic media (including documents, books, research objects, multimedia materials and digital libraries) as well as academics researching more formal aspects of the interactions between such resources and their users. We also particularly invite entrepreneurs and developers interested in enhancing electronic media using Semantic Web technologies with a user-centered approach.

We invite the submission of papers, demonstrations and posters which describe implementations or original research that are related (but are not limited) to the following areas of interest:

• Strategies for semantic publishing (technical, social, and economic)
• Approaches for consuming semantic representations of digital documents and electronic media
• Open and shared semantic bookmarks and annotations for mobile and device-independent use
• User-centered approaches for semantically annotating reading lists and/or library catalogues
• Applications of Semantic Web technologies for building personal or context-aware media libraries
• Approaches for interacting with context-aware electronic media (e.g. location-aware storytelling, context-sensitive mobile applications, use of geolocation, personalization, etc.)
• Applications for media recommendations and filtering using Semantic Web technologies
• Applications integrating natural language processing with approaches for semantic annotation of reading materials
• Applications leveraging the interoperability of semantic annotations for aggregation and crowd-sourcing
• Approaches for discipline-specific or task-specific information sharing and collaboration
• Social semantic approaches for using, publishing, and filtering scholarly objects and personal electronic media

To support reading, think about diversity of reading styles.

A study of “How examiners assess research theses” mentions the diversity:

[F]our examples give a good indication of the range of ‘reading styles’:

• A (Hum/Male/17) sets aside time to read the thesis. He checks who is in the references to see that the writers are there who should be there. Then he reads slowly, from the beginning like a book, but taking copious notes.
• B (Sc/Male/22) reads the thesis from cover to cover first without doing anything else. For the first read he is just trying to gain a general impression of what the thesis is about and whether it is a good thesis—that is, are the results worthwhile. He can also tell how much work has actually been done. After the first read he then ‘sits on it’ for a while. During the second reading he starts making notes and reading more critically. If it is an area with which he is not very familiar, he might read some of the references. He marks typographical errors, mistakes in calculations, etc., and makes a list of them. He also checks several of the references just to be sure they have been used appropriately.
• C (SocSc/Female/27) reads the abstract first and then the introduction and the conclusion, as well as the table of contents to see how the thesis is structured; and she familiarises herself with appendices so that she knows where everything is. Then she starts reading through; generally the literature review, and methodology, in the first weekend, and the findings, analysis and conclusions in the second weekend. The intervening week allows time for ideas to mull over in her mind. On the third weekend she writes the report.
• D (SocSc/Male/15) reads the thesis from cover to cover without marking it. He then schedules time to mark it, in about three sittings, again working from beginning to end. At this stage he ‘takes it apart’. Then he reads the whole thesis again.

Can you distinguish what is being said from how it is said?
In other words, what is a ‘proposition’?

Giving an operational definition of ‘proposition’ or of ‘propositional content’ is difficult. Turns out there’s a reason for that:

Metadiscourse does not simply support propositional content: it is the means by which propositional content is made coherent, intelligible and persuasive to a particular audience.

– Ken Hyland Metadiscourse p39¹.

I’m very struck by how the same content can be wrapped with different metadiscourse — resulting in different genres for distinct audiences. When the “same” content is reformulated, new meanings and emphasis may be added along the way. Popularization of science is rich in examples.

For instance, a Science article…

When branches of the host plant having similar oviposition sites were placed in the area, no investigations were made by the H. hewitsoni females.

gets transformed into a Scientific American article…

I collected lengths of P. pittieri vines with newly developed shoots and placed them in the patch of vines that was being regular revisited. The females did not, however, investigate the potential egg-laying sites I had supplied.

This shows the difficulty of making clean separations between the content and the metadiscourse:

“The ‘content’, or subject matter, remains the same but the meanings have changed considerably. This is because the meaning of a text is not just about the propositional material or what the text could be said to be about. It is the complete package, the result of an interactive process between the producer and receiver of a text in which the writer chooses forms and expressions which will best convey his or her material, stance and attitudes.

- Ken Hyland Metadiscourse p39

Example from Hyland (page 21), which credits Myers Writing Biology: Texts in the Social Construction of Scientific Knowledge 1990 (180).

1. I’m really enjoying Ken Hyland’s Metadiscourse. Thanks to Sean O’Riain for a wonderful loan! I’m not ready to summarize his thoughts about what metadiscourse is — for one thing I’m only halfway through.

Yesterday I spoke at Beyond the PDF about use cases for reading. Slides are below; the presentation was also webcast, so I hope to share a video recording when it becomes available. The video is now on Youtube (part of the Beyond the PDF video playlist) and below.

Thanks to the DERI Social Software Unit for feedback on an earlier version of this presentation. I’m particularly grateful to Allen Renear and Carole Palmer from UIUC, whose call for ontology-aware reading tools pushed me down this path, and to Geoffrey Bilder who presented these ideas in a way I couldn’t help thinking about and remixing. Cathy Marshall’s clear exposition, in Reading and Writing the Electronic Book was fundamental to digging deeper.

Nicole Henning suggests that academic libraries and scholarly presses work together to create the ultimate mobile app for scholarly ereading. I think about the requirements a bit differently, in terms of the functional requirements.

The main functions are obtaining materials, reading them, organizing them, keeping them, and sharing them.

For obtaining materials, the key new requirement is to simplify authentication: handle campus authentication systems and personal subscriptions. Multiple credentialed identities should be supported. A secondary consideration is that RSS feeds (e.g. for journal tables of contents) should be supported.

For reading materials, the key requirement is to support multiple formats in the same application. I don’t know of a web app or mobile app that supports PDF, EPUB, and HTML. Reading interfaces matter: look to Stanza and Ibis Reader for best-in-class examples.

For organizing materials, the key is synergy between the user’s data and existing data. Allow tags, folders, and multiple collections. But also leverage existing publisher and library metadata. Keep it flexible, allowing the user to modify metadata for personal use (e.g. for consistency or personal terminology) and to optionally submit corrections.

For keeping materials, import, export, and sync content from the user’s chosen cloud-based storage and WebDAV servers. No other device (e.g. laptop or desktop) should be needed.

For sharing materials, support lightweight micropublishing on social networks and email; networks should be extensible and user-customizable. Sync to or integrate with citation managers and social cataloging/reading list management systems.

Regardless of the ultimate system, I’d stress that device independence is important, meaning that an HTML5 website would probably the place to start: look to Ibis Reader as a model.

Springer’s LaTeX search service (example results) allow searching for LaTeX strings or finding the LaTeX equations in an article. Since LaTeX is used to markup equations in many scientific publications this could be an interesting way to find related work or view an equation-centric summary of a paper.

You can provide a LaTeX string, and Springer says that besides exact matches they can return similar LaTeX strings:

Or, you can search by DOI or title to get all the equations in a given publication:

Under each equation in the search results you can click “show LaTeX code”:

Right now it just searches Springer’s publications; Springer would like to add open access databases and preprint servers. Coverage even in Springer journals seems spotty: I couldn’t find two particular discrete math articles papers, so I’ve written Springer for clarification. As far as I can tell, there’s no way to get from SpringerLink to this LaTeX search yet: it’s a shame, because “show all equations in this article” would be useful, even with the proviso that only LaTeX equations were shown.

A nice touch is their sandbox where you can test LaTeX code, with a LaTeX dictionary conveniently below.

Provenance, Dan Conover says, can drive the adoption of semantic technologies:

Imagine a global economy in which every piece of information is linked directly to its meaning and origin. In which queries produce answers, not expensive, time-consuming evaluation tasks. Imagine a world in which reliable, intelligent information structures give everyone an equal ability to make profitable decisions, or in many cases, profitable new information products. Imagine companies that get paid for the information they generate or collect based on its value to end users, rather than on the transitory attention it generates as it passes across a screen before disappearing into oblivion.

Now imagine copyright and intellectual property laws that give us practical ways of tracing the value of original contributions and collecting and distributing marginal payments across vast scales.

That’s the Semantic Economy.

- Dan Conover on the semantic economy (my emphasis added).
via Bora Zivkovic on Twitter

I wonder if he’s seen the W3 Provenance XG Final Report yet. Two parts are particularly relevant: the dimensions of provenance and the news aggregator scenario. Truly making provenance pay will require both Management of provenance (especially Access and Scale) and Content provenance around Attribution.

Go read the rest of what Dan Conover says about the semantic economy. Pay particular attention to the end: Dan says that he’s working on a functional spec for a Semantic Content Management System — a RDF-based middleware so easy that writers and editors will want to use it. I know you’re thinking of Drupal and of the Semantic Desktop; we’ll see how he’s differentiating: He invites further conversation.

I’m definitely going to have a closer look at his ideas: I like the way he thinks, and this isn’t the first time I’ve noticed his ideas for making Linked Data profitable.
