a.k.a. "Human Search Engine". A chance for you to ask a roomful of code4libbers anything that's on your mind: questions seeking answers (short or long), requests for things (hardware, software, skills, or help), or offers of things. We'll keep the pace fast, and the answers faster. Come with questions and line up at the start of the session and we'll go through as many as we can; sometimes we'll stop at finding the right person or people to answer a query and it'll be up to you to find each other after the session. Third time at code4libcon! (Thanks to Ka-Ping Yee and Dan Chudnov for the inspiration/explanation, reused here in part.)
Relevance Ranking in the Scholarly Domain
- Tamar Sadeh, PhD, Ex Libris Group, email@example.com

The greatest challenge for discovery systems is how to provide users with the most relevant search results, given the immense landscape of available content. In a manner that is similar to human interaction between two parties, in which each person adjusts to the other in tone, language, and subject matter, discovery systems would ideally be sophisticated and flexible enough to adjust their algorithms to individual users and each user’s information needs.
When evaluating the relevance of an item to a specific user in a specific context, relevance-ranking algorithms need to take into account, in addition to the degree to which the item matches the query, information that is not embodied in the item itself. Such information, which includes the item’s scholarly value, the type of search that the user is conducting (e.g., an exploratory search or a known-item search), and other factors, enables a discovery system to fulfill user expectations that have been shaped by experience with Web search engines.

Web based library search engines are traditionally operated using keys, input fields, buttons, and links. Being equipped with touch screens, accelerometers, GPS's, and cameras, smartphones and tablets offer a whole new range of input options.
In this talk we'll demonstrate some of our ideas of how to utilise these new input options interacting with a search engine. The basic idea is to have no traditional GUI input elements, but only use touch interactions (pinch, zoom, swipe, long-press, etc) and gestures (shake, tilt, turn, etc.). Using these interactions, we’ll demonstrate how to:
- do searches
- toggle search result views
- switch pages
- request materials, add to favourites
- interact with your stuff, renew items
We'll also show you some (conceptual) ideas about using the device camera for locating and checking out materials.
Practical Agile: What's Working for Stanford, Blacklight, and Hydra

Agile development techniques can be difficult to adopt in the context of library software development. Maybe your shop has only one or two developers, or you always have too many simultaneous projects. Maybe your new projects can’t be started until 27 librarians reach consensus on the specifications.
This talk will present successful Agile- and Silicon-Valley-inspired practices we’ve adopted at Stanford and/or in the Blacklight and Hydra projects. We’ve targeted developer happiness as well as improved productivity with our recent changes. User stories, dead week, sight lines … it’ll be a grab bag of goodies to bring back to your institution, including some ideas on how to adopt these practices without overt management buy in.
Lies, Damned Lies, and Lines of Code Per Day

We've all heard about that one study that showed that Pair Programming was 20% efficient than working alone. Or maybe you saw on a blog that study that showed that programmers who write fewer lines of code per day are more efficient...or was it less efficient? And of course, we all know that programmers who work in (Ruby|Python|Java|C|Erlang) have been shown to be more efficient.
A quick examination of some of the research surrounding programming efficiency and methodology, with a focus on personal productivity, and how to incorporate the more believable research into your own team's workflow.
In-browser data storage and me
- Jason Casden, North Carolina State University Libraries, email@example.com

When it comes to storing data in web browsers on a semi-persistent basis, there are several partially-adopted, semi-deprecated, product-specific, or even universally accepted options. These include models such as key-value stores, relational databases, and object stores. I will present some of these options and discuss possible applications of these technologies in library services. In addition to quoting heavily from Mark Pilgrim's excellent chapter on this topic, I will weave in my own experience utilizing in-browser data storage in an iPad-based data collection tool to successfully improve performance and data stability while reducing network dependence.

Indexing big data with Tika, Solr & map-reduce

The Web Archiving Service at the California Digital Library has crawled a large amount of data, in every format found on the web: 30 TB, comprising about 600 million fetched URLs. In this talk we will discuss how we parsed this data using Tika and map-reduce, and how we indexed this data with Solr, tweaked the relevance ranking, and were able to provide our users with a better search experience.
NoSQL Bibliographic Records: Implementing a Native FRBR Datastore with Redis
- Jeremy Nelson, Colorado College, firstname.lastname@example.org
code4lib 2012, Wednesday, February 8 2012, 10:55-11:15
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.
Stack View: A Library Browsing Tool

In an effort to recreate and build upon the traditional method of browsing a physical library, we used catalog data, including dimensions and page count, to create a virtual shelf.
Building research applications with Mendeley

This is partly a tool talk and partly a big idea one.
