Philosophically, materialists and idealists understand the world differently. In materialist theory information directly represents the natural world, whereas idealism understands it to be the very structure of thought. Some of the problems arising between information theory and the actual practice of librarianship are due to mixing concepts from incompatible theories. The concept of information favored by materialist theories is not interchangeable with the concepts preferred by idealists and critical theorists. Materialism overemphasizes the empirical features of information, while giving short shrift to the possibility that information can be both factual and evaluative. Consequently, this leads to theories of information which are out of touch with the values, norms and purposes of ordinary people.
TheBrain provides advanced Mind Mapping Software and Knowledge Management Software that uses visualization and intuitive concept maps to enable intuitive searching, browsing, and organization of information. Disparate data sources are integrated and connected into an associative knowledge network to enable recall, understanding, and communication.
Call for the internet. As Director of the Office of Scientific Research and Development, Dr. Vannevar Bush has coordinated the activities of some six thousand leading American scientists in the application of science to warfare. In this significant article he holds up an incentive for scientists when the fighting has ceased. He urges that men of science should then turn to the massive task of making more accessible our bewildering store of knowledge.
One can gain a lot of insight into the structure of a network by analzing the eigenvalues and eigenvectors of its adjacency matrix. The connection between spectral parameters and the more combinatorial properties of networks and datasets is a subtle issue, and while many results have been established about this connection, it is still not fully understood. This connection has also led to a number of applications, including the development of link analysis algorithms for Web search.
