摘要： A System, method and application for creating comprehensive multiple mixed media knowledge storage and management, discovery and retrieval utilizing novel indexing and querying applied to content from multiple media formats from disparate sources is disclosed. Depending on the media format the system breaks down the source information in any media into constituent units ("tokens") using a reference corpus of labeled tokens ("training set"). The details of tokens are stored in an inverted index with available reference data such as location in the file, time, source file and additional information related to the token such as quantitative similarity to the best-match token(s) in the training set etc. During retrieval, a query comprising of single element in any media; a multimedia element or a combination of such elements including a sequence of such elements in a time line is similarly broken down into constituent units to generate a novel query structure. This enables discovery and retrieval of knowledge from multiple source documents in different media combined to provide results which could include prediction of events; discovery of events leading up to or contributing to an outcome of interest and retrieval of documents or sections thereof, all ordered by relevance depending on the query and its context.
