Abstract: A system and method for real time alert, adapted to receive information streams, to analyze the content of said stream in real time and to generate an alert. Said system and method allow to provide real time alerts based upon an analysis of a reception of information packets generated from a plurality of information sourced during a predetermined period of time.

Abstract: A system and method for real time search that matches a plurality of client queries against a plurality of terms extracted from a plurality of information packets. The method and system allows implementation of complex matching techniques in real time. The method and system provides that a group of information packets originating from a single information source is checked in order to provide a query result. In addition, it provides that received information packets and information representative of a reception of extracted terms are stored in a manner that allows fast insertion and deletion of content.

Abstract: A method for calculating a relevancy value of a document out of a plurality of documents, the method includes the steps of: (a) receiving a client query defining an information interest of the client; (b) scanning each document with at least a portion of the client query and with at least one real time term to generate a first and a second set of relevancy values; a real time term are extracted from (i) information packets generated by real time information sources, (ii) other client queries or (iii) alert results, and (c) calculating a combination of relevancy values of the first and second sets of each document to generate the relevancy value of each document.
