This article argues that a cooperatively-built well-organized shared knowledge base is a new – and, from certain viewpoints, optimal – kind of support (refining and integrating other kinds of supports) for the following three complementary tasks: learning about living entities (and how to identify them), supporting their identification, and sharing knowledge about them. This article gives the i...

Knowledge management has an increasing importance in organizations. Not only as a way to capture knowledge, but also to allow the incorporation of knowledge in products and services provided. Wikis are finding their way into organizational departments serving as collaborative tools for knowledge creation. In this paper, we study how an organizational wiki can be used as a knowledge management (...

We present AceWiki, a prototype of a new kind of semantic wiki using the controlled natural language Attempto Controlled English (ACE) for representing its content. ACE is a subset of English with a restricted grammar and a formal semantics. The use of ACE has two important advantages over existing semantic wikis. First, we can improve the usability and achieve a shallow learning curve. Second,...

We present Wikulu1, a system focusing on supporting wiki users with their everyday tasks by means of an intelligent interface. Wikulu is implemented as an extensible architecture which transparently integrates natural language processing (NLP) techniques with wikis. It is designed to be deployed with any wiki platform, and the current prototype integrates a wide range of NLP algorithms such as ...

In 1995, Ward Cunningham wanted to enable programmers to discuss and collaboratively document design patterns on his website, Portland Pattern Repository. To this end, he created a new kind of server software that allowed any page to be freely edited by any user. He called his new creation a wiki.1 Inspired by this first wiki, a number of other wikis have sprang up, the best known of which is W...

the fact that the stress response affects testicular function in several animal species, has been established for several decades. the aim of the present review was to describe how the mechanisms involved in the acute stress response affect directly or indirectly the testicular function at different levels. Both neuroendocrine axes linked to the stress response, i.e., the sympathetic-adrenomedu...

Wikis are an important part of collaboration in E-Learning, as they allow easy modification mate-rial of other contributors and integrate multimedia elements. Versioning of changes is built-in, but this refers to individual actions of one person only. Especially in E-Learning both aspects can be problematic, as not individual changes but larger activities are needed for a personal learning hist...
