Abstract: A system and a method are disclosed for techniques and processes for stored online content, e.g., digital advertisement objects in a personally controlled repository. The content, e.g., digital advertisement objects, may be enhanced with additional metadata, extended upon by user generated and/or collaborated metadata, as well as the communication used by both the originating user storing the content, e.g., digital advertisement as well as those to whom said user may share the advertising objects with, and the advertiser, publisher and distributor of the content, e.g., digital advertisement. The systems and methods described herein allow for the control and management of distributed advertisements within a controlled repository.

Abstract: An electronic document is parsed to remove irrelevant text and to identify the significant elements of the retained text. The elements are assigned scores representing their significance to the topical content of the document. A matrix of element-pairs is constructed such that the matrix nodes represent the result of one or more functions of the scores and other attributes of the paired elements. The resulting matrix is a compact representation of topical content that affords great precision in information retrieval applications that depend on measurements of the relatedness of topical content.
