Abstract: A method for determining an intention encoded in a given text communication, the method comprising: receiving a written text; identifying test regexes comprised in the text that are usable to indicate an intention included in the text; determining degrees of entailment of the test regexes with intention indicator regexes (IIRs) comprised in a set of IRRs; and inferring the intention based on the determined degrees of entailment.

Abstract: A method comprising using at least one hardware processor for: receiving first a set of keywords associated with a first advertising platform; receiving second a set of keywords associated with a second advertising platform; defining binary relations between the first and second sets of keywords; applying formal concept analysis (FCA) to the binary relations, to produce a concept lattice; and updating the concept lattice responsive to changes in the first or second sets of keywords.

Abstract: Provided is a system for communication, including: a non-transitory processor configured to: (a) determine a group of messages including a plurality of optional messages for a user in response to obtaining of user identification information identifying the user; (b) obtain performance information for each one of plurality of optional messages; (c) obtain historical interactions data pertaining to interactions which are included in a series of user interactions, where at least one of the interactions of the series includes communication of digital media over a network connection to the user; and (d) select an elect message out of the plurality of optional messages based on the historical interactions data and on the performance information; and a communication interface operable and configured to transmit information of the elect message over a communication channel.
