Bioephemera is about the intersection of science - mainly biology - and the arts. I am a biologist and an artist, but I’ve always felt awkward identifying myself as both

But increasingly data is being produced without tags, and this lack of tagging makes it difficult or impossible to do intelligent aggregate and selective searches. Folksonomies and taxonomies have become powerful tools in the right hands, but too much data is created without any thoughts or any science about how that data will be maintained or re-purposed in the longer term.

I mean an open source desktop can facilitate metadata tagging from the desktop. Open source tools that interface with databases can pass metadata to and from the database. Editors (even 2d paint, 2d illustration and 3d editors) can become part of the metadata workflow.

University of California researchers are claiming they’ve added “common sense” to computers’ ability to recognize objects in photographs. 

Introduction. It is argued that the actual elements of typical browsing episodes have not been well captured by common approaches to the concept to date. Method. Empirical research results reported by previous researchers are presented and closely analysed. Analysis. Based on the issues raised by the above research review, the components of browsing are closely analysed and developed. Browsing is seen to consist of a series of four steps, iterated indefinitely until the end of a browsing episode: 1) glimpsing a field of vision, 2) selecting or sampling a physical or informational object within the field of vision, 3) examining the object, 4) acquiring the object (conceptually and/or physically) or abandoning it. Not all of these elements need be present in every browsing episode, though multiple glimpses are seen to be the minimum to constitute the act. Results. This concept of browsing is then shown to have persuasive support in the psychological and anthropological literature, where research on visual search, curiosity and exploratory behaviour all find harmony with this perspective. Conclusions. It is argued that this conception of browsing is closer to real human behaviour than other approaches. Implications for better information system design are developed.

This annotated bibliography was commissioned to support the NSDL Evaluation Workshop (planned for October 2003) that will 1) explore the issues around evaluating the impact of digital libraries on education and that will 2) begin developing a strategy to evaluate the impact of the National Science Digital Library (NSDL) on STEM education. The bibliography’s purpose, then, is to identify research to date on evaluating the impact of digital libraries on learning and teaching. It contains a Summary & Analysis section, which defines terms, makes observations about the literature, reviews the resources included, highlights issues, and suggests areas for further consideration.

To be faced with a document collection and not to be able to find the information you know exists somewhere within it is a problem as old as the existence of document collections. Information Architecture is the discipline dealing with the modern version of this problem: how to organize web sites so that users actually can find what they are looking for. Information architects have so far applied known and well-tried tools from library science to solve this problem, and now topic maps are sailing up as another potential tool for information architects. This raises the question of how topic maps compare with the traditional solutions, and that is the question this paper attempts to address. The paper argues that topic maps go beyond the traditional solutions in the sense that it provides a framework within which they can be represented as they are, but also extended in ways which significantly improve information retrieval.
