I tried to decode my content with base64 decoder, but resulting I didn't get my actual content The content of sample.pdf: The world is changing, and changing priorities for the development of society. Use of information technology accelerates this process. Information treated as a commodity, and its role as a commodity increases, while the value of information depends on the timing and the cost of its treatment. The growth of complexity and amount of information makes the question of finding new approaches to access it as the use of traditional technology results in longer and the cost of developing software tools to access information. Existing systems provide search information sources of the same type, while ignoring others. For example, systems such as Yandex, Rambler, Google, Yahoo provide information search in the databases of keywords corresponding to certain HTML - pages, the rest of the same information (audio, video and other data other than HTML - pages) located on servers in the Internet remains unaddressed. This determines the relevance of the work to develop more efficient methods for constructing systems of access to distributed heterogeneous information.
