Nineteen tanniferous browse plants were collected from South Africa to investigate their digestibility, gas production (GP) characteristics and methane production. Fresh samples were collected, dried in forced oven, and ground and analyzed for nutrient composition. In vitro GP and in vitro organic matter digestibility (IVOMD) were determined using rumen fluid collected, strained and anaerobical...

We present an original navigation approach to explore data in the framework of the semantic web. Before navigation, data are represented and integrated by jointly using Topic Maps and description logics. Our navigation approach improves the traditional web navigation with two specificities. First, the navigation paths are semantic instead of structural links. Second, it is a subject-centric ins...

We propose a client-side agent for exploring and categorizing documents on the World Wide Web. As the user browses the Web using a usual web browser, this agent is designed to aid the user by classifying the documents the user nds most interesting into clusters. The agent carries out the task completely automatically and autonomously, with as little user intervention as the user desires. The pr...

In this paper, we present visualizations of parts of the network of documents comprising the World Wide Web. We describe how we are using the Hy + visualization system to visualize the portion of the World Wide Web explored during a browsing session. As the user browses, the web browser communicates the URL and title of each document fetched as well as all the anchors contained in the document....

Web crawler is a software program that browses WWW in an automated or orderly fashion, and the process is known as web crawling. A web crawler creates the copy of the visited pages so that when required later on, it will index the pages and processing becomes faster. This paper discuss the various techniques of the web crawling through which search becomes faster. In this paper studied has been...

Although shared software repositories are commonly used during software development, it is typical that a software developer browses and edits a local snapshot of the software under development. Developers periodically check their changes into the software repository; however, their interaction with the local copy is not recorded. Local interaction histories are a valuable source of information...

In this paper we describe Calvin, an intelligent agent that learns user interests by monitoring user activities while he/she searches and browses the Web. The user pro le is created and maintained from a contentbased and event-based analysis of the visited pages using Inductive Logic Programming. The user submits queries which are expanded considering the information represented in her/his pro ...

The goal of this work is to study how individual learning helps adaptive agents, living in an Artificial Life world, to develop correct behaviors when seeking for information in distributed and dynamic environments. We developed a prototype of an information retrieval system where a population of adaptive organisms browses through the environment, trying to find relevant information for a speci...
