Music has changed and evolved through time and time tells that it has always been for the better. In our study, we have implemented Genetic Algorithms for the generation of music by music mixing to provide willing music lovers, the first step to personalize music to suit their liking. A music loop library, containing a list of all tentative loops which are to be used in the remix production alongwith the parameters which define them, is used for this purpose. A loop is an endless band of tape or music allowing continuous repetition. These loops cover all the major music instrument families with particular emphasis on Indian musical instruments as they have been extracted from Indian songs after careful observation using a sound editor. The combinations of different loops for the analysis is run through genetic algorithms. Some important parameters of a loop from the point of view of music mixing are: Depth, BPM (beats per minute), length of the loop and type of the instrument. A fitness function is calculated for the genetic algorithm to rank various combinations of loops for the next generation. The best loop combination can be selected out of the final set of population.

Ontology is a fundamental data object for organizing knowledge in a structured way in many areas ranging from philosophy to Knowledge Management. Knowledge capture, knowledge integration and knowledge delivery are the essential parts of dynamic knowledge management. E-Learning is considered to be an integral part of knowledge delivery system. Information architect plays an important role in developing the system, and are primarily responsible for capturing and modeling knowledge from various Information sources as a part of eLearning. Ontology is found to be useful and efficient as a basis to capture the knowledge, model it in a structured way and disseminate it for further processing from various information sources. In this paper, we present a brief description on the role of ontology in e-learning and review the ontology building tools. The purpose for reviewing ontology building tools is to determine the toolkit most suitable for ontology creation, editing, and mind/concept mapping from the view points of Information Architects (IAs) who play a significant role in designing knowledge management systems. The paper also gives a fundamental understanding of ontology tools available on the market as open source products as well as commercial products in terms of their capability, availability, enhancement and further development. We provide a ranked list of the tools based on our needs and suitability for the IAs.
