Program for determination of probable sources of insider information

<p>Report 22 p., 4 ch., 2 pics, 1 table, 8 sources, 4 applications</p><p>Keywords: insider information, information retrieval, plsa</p><p>Object of this project is an application for determination of probable sources of insider information.</p><p>Purpose of this project is an implementation of an application, capable of analysis of large text data, support analyst in determining probable sources of insider information.</p><p>An application is a local search machine, capable of information retrieval from user-determined set of documents, search for semantic relevance between documents, and determine terms, altered by intention.</p><p>During research there has been done an analysis of algorithms for determination of semantic likeliness of documents, indexing algorithms, best fitted to execute given task. Also existing solutions were analyzed, their capability of performing given task was evaluated.</p><p>Developed application is capable of analysis of large sets of text data both in Russian or English, capable to execute information retrieval on user provided set of documents. After insignificant modification application will be able to perform information retrieval in other languages.</p><p>As a result of a project an application has been developed, fitting given tasks, and able not only to determine probable sources of insider information, but also perform other information retrieval tasks.</p><p>Therefore, development has potential for expansion, and after minor modification will be able to solve wider range of tasks than primarily defined.&nbsp;</p>
