20 Things I Learned About Browsers and the Web
“20 Things I Learned About Browsers and the Web” is a short guide for anyone who’s curious about the basics of browsers and the web. Here’s what you’ll find here:

First we’ll look at the Internet, the very backbone that allows the web to exist. We’ll also take a look at how the web is used today, through cloud computing and web apps.

Then, we’ll introduce the building blocks of web pages like HTML and JavaScript, and review how their invention and evolution have changed the websites you visit every day. We’ll also take a look at the modern browser and how it helps users browse the web more safely and securely.

Finally, we’ll look ahead to the exciting innovations in browsers and web technologies that we believe will give us all even faster and more immersive online experiences in the future.

Hjørland, B. (2010). The foundation of the concept of relevance. Journal of the American Society for Information Science and Technology, 61(2), 217-237.
In 1975 Tefko Saracevic declared “the subject knowledge view” to be the most fundamental perspective of relevance. This paper examines the assumptions in different views of relevance, including “the system's view” and “the user's view” and offers a reinterpretation of these views. The paper finds that what was regarded as the most fundamental view by Saracevic in 1975 has not since been considered (with very few exceptions). Other views, which are based on less fruitful assumptions, have dominated the discourse on relevance in information retrieval and information science. Many authors have reexamined the concept of relevance in information science, but have neglected the subject knowledge view, hence basic theoretical assumptions seem not to have been properly addressed. It is as urgent now as it was in 1975 seriously to consider “the subject knowledge view” of relevance (which may also be termed “the epistemological view”). The concept of relevance, like other basic concepts, is influenced by overall approaches to information science, such as the cognitive view and the domain-analytic view. There is today a trend toward a social paradigm for information science. This paper offers an understanding of relevance from such a social point of view.

Retraction Watch
Although retractions are on average occurring sooner after publication than in the past, citation analysis shows that they are not being recognised by subsequent users of the work. Findings suggest that editors and institutional officials are taking more responsibility for correcting the scientific record but that reasons published in the retraction notice are not always reliable. More aggressive means of notification to the scientific community appear to be necessary.

Cory Doctorow: It’s Time to Stop Talking About Copyright
There just isn’t such a thing as ‘‘copyright policy’’ anymore. Every modern copyright policy becomes Internet policy – policy that touches on every aspect of how we use the net. And as we make the transition from a world where everything we do includes an online component to a world where everything we do requires an online component, it’s becoming the case that there’s no such thing as ‘‘Internet policy’’ – there’s just policy.

Using critical thinking to conduct effective searches of online resources
While the number of online databases and other resources continues to rise, the quality and effectiveness of database searches does not. Over 80% of academic, public and school libraries offer some form of Internet access (American Library Association, 2000); thousands of full-text electronic journals and serials are available online. However, Hertzberg & Rudner (1999) found that most searches are cursory and ineffective, and they provide extensive recommendations regarding the mechanics of searching. A firm grounding in the mechanics of searching is vital, but an effective search is also an exercise in inquiry and critical thinking. We begin searching a topic with certain questions; as we collect information, we form hypotheses about the topic. These hypotheses in turn guide further searching, and are elaborated, discarded or modified as we learn more.

This document complements guidelines addressing the mechanics of online searching by considering how treating searching as exercises in critical thinking can improve our use of online resources. We address the use of metacognition, hypothesis-testing, and argumentation, providing illustrative examples, and links to tools that can facilitate the process.

Bates, The Invisible Substrate of Information Science
The explicit, above-the-water-line paradigm of information science is well known and widely discussed. Every disciplinary paradigm, however, contains elements that are less conscious and explicit in the thinking of its practitioners. The purpose of this article is to elucidate key elements of the below-the-water-line portion of the information science paradigm. Particular emphasis is given to information science's role as a meta-science - conducting research and developing theory around the documentary products of other disciplines and activities. The mental activities of the professional practice of the field are seen to center around representation and organization of information rather than knowing information. It is argued that such representation engages fundamentally different talents and skills from those required in other professions and intellectual disciplines. Methodological approaches and values of information science are also considered.

Information as Thing
Three meanings of information are distinguished: Information-as-process; information-as-knowledge; and information-as-thing, the attributive use of information to denote things regarded as informative. The nature and characteristics of information-as-thing are discussed, using an indirect approach (What things are informative?). Varieties of information-as-thing include data, text, documents, objects, and events. On this view information includes but extends beyond communication. Whatever information storage and retrieval systems store and retrieve is necessarily information-as-thing. These three meanings of information, along with information processing, offer a basis for classifying disparate information-related activities (e.g., rhetoric, bibliographic retrieval, statistical analysis) and, thereby, suggest a topography for information science.

Harry, D., Green, J., & Donath, J. (2009). Integrating Backchannels in Physical Space. Conference on Human Factors in Computing Systems. In this paper, we describe, a web based backchannel system that focuses on providing greater audience participation during question and answer sessions. The system allows audience members to use a web-based service to propose questions and comments, and to vote on the questions of others. Top rated submissions are projected into the presentation space where audience members, moderators, and panelists can see them. We discuss the results of deploying this system at many different kinds of conferences and relate those results to the particular design of our system, demonstrating how backchannel systems can be more than just shared chat rooms. From our experience with this work, we discuss the broader implications of configurable mediated social spaces and how subtle design decisions can influence user experience.  backchannel  presentation  CMC  pedagogy  inls200  filetype:pdf  media:document

Hahn, T. B. (2003). What Has Information Science Contributed to the World? Bulletin of the American Society for Information Science and Technology, 29(4). The Council of Scientific Society Presidents recently asked me to respond to a survey question: “What were the most important seminal five to seven discoveries in the field represented by your professional society in the 20th century?” Such a question raises several complex issues, such as what are the most remarkable achievements unique to the field of information science in the past 100 years? Who are the individuals who were responsible for each one? Just what constitutes our field as separate from other fields such as computer science, librarianship, chemistry, engineering, medicine, management, law or education? How do our research methods differ from those of the social sciences, operations research, linguistics and others from which we have obviously borrowed?

How to get students to find and read 94 articles before the next class
From Michael Wesch's Digital Ethnography blog My student-researchers and I tried something a little different to kick off our semester. Instead of the standard syllabus that requires everybody to read a few articles to discuss, we decided instead to organize ourselves into a Smart Mob that would try to read a good hunk of the literature on a single topic in one go. Each student was required to find 5 articles, read them, and summarize them; uploading their summaries (or the author’s own abstract) into a ZohoCreator form. ZohoCreator is a free service that allows you to create database input forms.

Gilliland, A. J. (1998). Setting the Stage. In M. Baca (Ed.), Introduction to Metadata: Pathways to Digital Information. Los Angeles: Getty Research Institute.
Metadata, literally "data about data," has become a widely used yet still frequently underspecified term that is understood in different ways by the diverse professional communities that design, create, describe, preserve, and use information systems and resources. It is a construct that has been around for as long as humans have been organizing information, albeit transparently in many cases, and today we create and interact with it in increasingly digital ways. For the past hundred years at least, the creation and management of metadata has primarily been the responsibility of information professionals engaged in cataloging, classification, and indexing; but as information resources are increasingly put online by the general public, metadata considerations are no longer solely the province of information professionals.

A simple, prima facie argument in favor of the Semantic Web
I do a bit with so-called Semantic Web technologies (OK, I've written a couple of articles, have a book proposal in the works, and am about to start a job as a Semantic web researcher ... as I said, "a bit"), but I must confess to never really getting certain aspects of it. I like logic programming, and I'm certainly interested in knowledge representation, and I do a bunch of web stuff so I must be a Semantic Web person. However, some bit never clicked for me, some key shared assumption left me feeling a bit out of the flow of things. I used to characterize this as having more of a logician/philosopher background, but that didn't seem quite right. During the recent Google and SOAP furor, I had a little insight that led to the following prima facie argument for the Semantic Web. I hope it helps other people "get it".

Numbers are making their way into the smallest crevices of our lives. We have pedometers in the soles of our shoes and phones that can post our location as we move around town. We can tweet what we eat into a database and subscribe to Web services that track our finances. There are sites and programs for monitoring mood, pain, blood sugar, blood pressure, heart rate, cognitive alacrity, menstruation, and prayers. Even sleep—a challenge to self-track, obviously, since you're unconscious—is yielding to the skill of the widget maker. With an accelerometer and some decent algorithms, you will soon be able to record your sleep patterns with technology that costs less than $100.
