Frank van Harmelen’s laws of information

November 1st, 2011

What are the laws of information? Frank van Harmelen proposes seven laws of information science in his keynote to the Semantic Web community at ISWC2011. ((He presents them as “computer science laws” underlying the Semantic Web; yet they are laws about knowledge. This makes them candidate laws of information science, in my terminology.))

  1. Factual knowledge is a graph. ((“The vast majority of our factual knowledge consists of simple relationships between things,
    represented as an ground instance of a binary predicate.
    And lots of these relations between things together form a giant graph.”))
  2. Terminological knowledge is a hierarchy.
  3. Terminological knowledge is much smaller ((by 1-2 orders of magnitude)) than the factual knowledge.
  4. Terminological knowledge is of low complexity. ((This is seen in “the unreasonable effectiveness of low-expressive KR”: “the information universe is apparently structured in such a way that the double exponential worse case complexity bounds don’t hit us in practice.”))
  5. Heterogeneity is unavoidable. ((But heterogeneity is solvable through mostly social, cultural, and economic means (algorithms contribute a little bit). ))
  6. Publication should be distributed, computation should be centralized to decrease speed: “The Web is not a database, and I don’t think it ever will be.”
  7. Knowledge is layered.
What do you think? If they are laws, can they be proven/disproven?

Semantic Web vocabularies in the Tower of Babel

I wish every presentation came with this sort of summary: slides and transcript, presented in a linear fashion. But these laws deserve more attention and discussion–especially from information scientists. So I needed something even punchier to share, (prioritized thanks to Karen).

The Legacy of Michael S. Hart

September 16th, 2011

ship sinking into a whirlpool near the Lone Tower

Sometimes people are important to you not for who they are, but for what they do. Michael S. Hart, the founder of Project Gutenberg, is one such person. While I never met him, Michael’s work has definitely impacted my life: The last book I finished ((The Book of Dragons, by Edith Nesbit: highly recommended, especially if you like silly explanations or fairy tales with morals.)), like most of my fiction reading over the past 3 years, was a public domain ebook. I love the illustrations.

KENBAK-1 from 1971

The first personal computer: KENBAK-1 (1971)

In 1971, the idea of pleasure reading on screens must have been novel. The personal computer had just been invented; a KENBAK-1 would set you back $750 — equivalent to $4200 in 2011 dollars ((CPI Inflation Calculator)).

Xerox Sigma V-SDS mainframe

Xerox Sigma V-SDS mainframe

Project Gutenberg’s first text — the U.S. Declaration of Independence — was keyed into a mainframe, about one month after Unix was first released ((Computer history timeline 1960-1980)) ((Project Gutenberg Digital Library Seeks To Spur Literacy:
Library hopes to offer 1 million electronic books in 100 languages
, 2007-07-20, Jeffrey Thomas)). That mainframe, a Xerox Sigma V, was one of the first 15 computers on the Internet (well, technically, ARPANET) ((Amazingly, this predated NCSA. You can see the building–Thomas Siebel–hosting the node thanks to a UIUC Communication Technology and Society class assignment)). Project Gutenberg is an echo of the generosity of some UIUC sysadmins: The first digital library began a gift back to the world in appreciation of access to that computer.

Thanks, Michael.

Understanding Wikipedia through the evolution of a single page

August 26th, 2011

“The only constant is change.” – Heraclitis

How well do you know Wikipedia? Get to know it a little better by looking at how your favorite article changes over time. To inspire you, here are two examples.

Jon Udell’s screencast about ‘Heavy Metal Umlaut’ is a classic, looking back (in 2005) at the first two years of that article. It points out the accumulation of information, vandalism (and its swift reversion), formatting changes, and issues around the verifiability of facts.

In a recent article for the Awl ((The Awl is *woefully* distracting. I urge you not to follow any links. (Thanks a lot Louis!) )), Emily Morris sifts through 2,303 edits of ‘Lolita’ to pull out nitpicking revision comments, interesting diffs, and statistics.

Forking conversations, forking documents

August 7th, 2011

When the topic of discussion changes, how do you indicate that? Tender Support seems clunky in some ways, but their forking mechanism helps conversations stay focused on their topic:

Forking with Tender Support

Lately forking has also been on my mind as the Library Linked Data group edits and reorganizes our draft report: wiki history and version control is helpful, but insufficient. What I miss most is a “fork” feature, where you could temporarily take ownership of a copy (socially, this indicates that something is a possibility, rather than the consensus; technically, it indicates provenance, would allow “show all forks of this”, and might help in merge changes back). Perhaps naming and tagging particular history items in MediaWiki could help address this, but I think really I want something like git.

I’ve seen a few examples of writing and editing prose with git; I’d like to get a better understanding of the best practices for making collaborative changes in texts with distributed version control systems. Surely somebody’s written up manuals on this?

091labs again!

August 4th, 2011

Yesterday, our local hackerspace/makerspace re-opened!

For awhile now, Fiacre O’Duinn has been talking about the shared purpose between libraries and these spaces:

The ideas that fuel hackerspaces, such as cooperation, resource and information sharing, self-directed education, and a diversity of views are concepts that are central to our profession’s ethos.

Not to mention the cool tech (3D printers, laser engravers, tool lending libraries, …) we’d like to see in libraries in the not-so-distant future.

It’s a conversation I hope to pick up with Willow & others (thx!)at CCCamp.

Citation management means different things to different people

August 3rd, 2011

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‘s ((See also A short review of BibDesk from MacResearch)) ‘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.

Sente, a first look

August 1st, 2011

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

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!

Extended deadline for STLR 2011

April 29th, 2011

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.

Consider submitting!

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

IMPORTANT DATES

*EXTENDED* Paper submission deadline: May 8th 2011

Supporting Reading

January 21st, 2011

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.

Wanted: the ultimate mobile app for scholarly ereading

January 7th, 2011

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.
