Vmn (1) where m ≤ k. Analogously, we can construct a similar matrix, the opponent’s content matrix at step m, which contains the issues’ values of the offers received by the opponent. We denote such matrix as Wm , where m ≤ k. Note that these matrices contain also missing values. As long as we receive and make new offers, the matrices will increase row by row. 1 During the negotiation process, the user is able to collect a lot of information related to the opponent’s preferences analysing the content of the received offers.
K}. The shape function, given an item, returns an offer to send to the counterpart. Practically, it selects which features of an item to include in the offer. In the next Section we give a formal description of the item set and the offer set. Formally, let O be the offer set, for each user u ∈ U , we define the shape function as shapeu : T −→ O The like function, given an offer, return a label (answer) which is related to the evaluatioLet A = {0, ⊥, 1} be the set of all possible answers to an offer, for each user u ∈ U , we define the like function as likeu : O −→ A The like function is invoked every time we need to evaluate a new opponent’s offer; we emphasize that both the values of the issues and the presence or absence of some issues play a role in the definition of this function.
Content creation has to be kept highly flexible, allowing for usage in different scenarios without any restrictions beforehand. Likewise, semantic capabilities were appreciated, enabling reuse of content generated in different manners. Security aspects have been identified on different levels: (1) Identification, authentication and authorisation – providing controlled access to the platform and the services offered by third parties. (2) Digital signatures - supporting a fast setup and legal binding of actions in a provable/undeniable fashion.
