my twitter infographic

my twitter infographicIt’s a mashup of two of my favorite things — data visualization and social media. Of course I’m going to make one.

The interesting thing is that for some reason I come across as a gamer according to the algorithms. Unless you count solitaire, sudoku, and Words with Friends, I’m not really a gamer at all. The PS2, games, and accessories I bought from my sister last November that is are sitting in a corner unassembled are also a testament to how little I game.

mapping ejournal use to subject areas

I had a thought last night as I was trying to fall asleep: what if I took our data on demand file that includes subjects and mashed it up with our consolidated JR1 use statistics? Could I get a better picture of the disciplines at my institution that are using ejournals? It’s definitely something worth looking at.

NASIG 2010: Linked Data and Libraries

Presenter: Eric Miller, Zepheira, LCC

Nowadays, we understand what the web is and the impact it has had on information sharing, but before it was developed, it was in a “vague but exciting” stage and few understood it. When we got started with the web, we really didn’t know what we were doing, but more importantly, the web was being developed so that it was flexible enough for smarter and more creative people to do amazing things.

“What did your website look like when you were in the fourth grade?” Kids are growing up with the web and it’s hard for them to comprehend life without it. [Dang, I’m old.]

This talk will be about linked data, its legacy, and how libraries can lead linked data. We have a huge opportunity to weave libraries into the fabric of libraries, and vice versa.

About five years ago, the BBC started making their content available in a service that allowed others to use and remix the delivery of the content in new ways. Rather than developing alternative platforms and creating new spaces, they focus on generating good content and letting someone else frame it. Other sources like NPR, the World Bank, and are doing the same sorts of things. Within the library community, these things are happening, as well. OCLC’s APIs are getting easier to use, and several national libraries are putting their OPACs on the web with APIs.

Obama’s open government initiative is another one of those “vague but exciting” things, and it charged agencies to come up with their own methods of making their content available via the web. Agencies are now struggling with the same issues and desires that libraries have been tackling for years. We need to recognize our potential role in moving this forward.

Linked data is a best practice for sharing data, connecting data, and uses the semantic web. Rather than leaving the data in their current formats, let’s put them together in ways they can be used on the wider web. It’s not the databases that make the web possible, it’s the web that makes the databases usable.

Human computation can be put to use in ways that assist computers to make information more usable. Captcha systems are great for blocking automated programs when needed, and by using human computation to decipher scanned text that is undecipherable by computers, ReCaptcha has been able to turn unusable data into a fantastic digital repository of old documents.

LEGOs have been around for decades, and their simple design ensures that new blocks work with old blocks. Most kids end up dumping all of their sets into one bucket, so no matter where the individual building blocks come from, they can be put together and rebuild in any way you can imagine. We could do this with our blocks of data, if they are designed well enough to fit together universally.

Our current applications, for the most part, are not designed to allow for the portability of data. We need to rethink application design so that the data becomes more portable. Web applications have, by neccesity, had to have some amount of portability. Users are becoming more empowered to use the data provided to them in their own way, and if they don’t get that from your service/product, then they go elsewhere.

Digital preservation repositories are discussing ways to open up their data so that users can remix and mashup data to meet their needs. This requires new ways of archiving, cataloging, and supplying the content. Allow users to select the facets of the data that they are interested in. Provide options for visualizing the raw data in a systematic way.

Linked data platforms create identifiers for every aspect of the data they contain, and these are the primary keys that join data together. Other content that is created can be combined to enhance the data generated by agencies and libraries, but we don’t share the identifiers well enough to allow others to properly link their content.

Web architecture starts with web identifiers. We can use URLs to identify things other than just documents, but we need to be consistent and we can’t change the URL structures if we want it to be persistent. A lack of trust in identifiers is slowing down linked data. Libraries have the opportunity to leverage our trust and data to provide control points and best practices for identifier curation.

A lot of work is happening in W3C. Libraries should be more involved in the conversation.

Enable human computation by providing the necessary identifiers back to data. Empower your users to use your data, and build a community around it. Don’t worry about creating the best system — wrap and expose your data using the web as a platform.

ER&L 2010: Where are we headed? Tools & Technologies for the future

Speakers: Ross Singer & Andrew Nagy

Software as a service saves the institution time and money because the infrastructure is hosted and maintained by someone else. Computing has gone from centralized, mainframe processing to an even mix of personal computers on an networked enterprise to once again a very centralized environment with cloud applications and thin clients.

Library resource discovery is, to a certain extent, already in the cloud. We use online databases and open web search, WorldCat, and next gen catalog interfaces. The next gen catalog places the focus on the institution’s resources, but it’s not the complete solution. (People see a search box and they want to run queries on it – doesn’t matter where it is or what it is.) The next gen catalog is only providing access to local resources, and while it looks like modern interfaces, the back end is still old-school library indexing that doesn’t work well with keyword searching.

Web-scale discovery is a one-stop shop that provides increased access, enhances research, and provides and increase ROI for the library. Our users don’t use Google because it’s Google, they use it because it’s simple, easy, and fast.

How do we make our data relevant when administration doesn’t think what we do is as important anymore? Linked data might be one solution. Unfortunately, we don’t do that very well. We are really good at identifying things but bad at linking them.

If every component of a record is given identifiers, it’s possible to generate all sorts of combinations and displays and search results via linking the identifiers together. RDF provides a framework for this.

Also, once we start using common identifiers, then we can pull in data from other sources to increase the richness of our metadata. Mashups FTW!

IL2009: Mashups for Library Data

Speakers: Nicole Engard

Mashups are easy ways to provide better services for our patrons. They add value to our websites and catalogs. They promote our services in the places our patrons frequent. And, it’s a learning experience.

We need to ask our vendors for APIs. We’re putting data into our systems, so we should be able to get it out. Take that data and mash it up with popular web services using RSS feeds.

Yahoo Pipes allows you to pull in many sources of data and mix it up to create something new with a clean, flow chart like interface. Don’t give up after your first try. Jody Fagan wrote an article in Computers in Libraries that inspired Engard to go back and try again.

Reading Radar takes the NYT Bestseller lists and merges it with data from Amazon to display more than just sales information (ratings, summaries, etc.). You could do that, but instead of having users go buy the book, link it to your library catalog. The New York Times has opened up a tremendous amount of content via APIs.

Bike Tours in CA is a mashup of Google Maps and ride data. Trulia, Zillow, and HousingMaps use a variety of sources to map real estate information. This We Know pulls in all sorts of government data about a location. Find more mashups at ProgrammableWeb.

What mashups should libraries be doing? First off, if you have multiple branches, create a Google Maps mashup of library locations. Share images of your collection on Flickr and pull that into your website (see Access Ceramics), letting Flickr do the heavy lifting of resizing the images and pulling content out via machine tags. Delicious provides many options for creating dynamically updating lists with code snippets to embed them in your website.

OPAC mashups require APIs, preferably those that can generate JavaScript, and finally you’ll need a programmer if you can’t get the information out in a way you can easily use it. LexisNexis Academic, WorldCat, and LibraryThing all have APIs you can use.

Ideas from Librarians: Mashup travel data from circulation data and various travel sources to provide better patron services. Grab MARC location data to plot information on a map. Pull data about media collection and combine it with IMDB and other resources. Subject RSS feeds from all resources for current articles (could do that already with a collection of journals with RSS feeds and Yahoo Pipes).
