77. A method of facilitating a service for a client over a communication and/or computer network, comprising: providing an access for the client over the network; receiving signals or an input from the client, said input can be used to identify the network address of a provider of said service; transmitting signals or data toward the provider of said service; facilitating for exchanging signals or data between the client and the provider of said service, wherein said service is performed by at least one program comprising instructions, executable by one or more processors, configured to process an input and provides two or more of the following: 1. providing an interactive environment to obtain the client's input in such a way that said input indicates a respective body of knowledge and a selected form of response from a plurality of forms of responses; accessing or building a first one or more data structures corresponding to at least one participation matrix representing participation of ontological subjects of a first predefined order into partitions or ontological subjects of a second predefined order of the body of knowledge; accessing, or building in real time, a second one or more data structures corresponding to association strengths between a plurality of ontological subjects of a predefined order; wherein said association strength is a function of: i. probability of occurrences of some of the ontological subjects of the first order in partitions or ontological subjects of a predefined order of the body of knowledge, and ii. co-occurrences of some ontological subjects of the first order in some of partitions or ontological subjects of a predefined order; accessing evaluated, or evaluating in real time, value significances for one or more partitions or one or more ontological subjects of the body of knowledge, based on data of one or more of said first and second one or more data structures and in respect to at least one significance aspect of the one or more partitions or one or more ontological subjects of the body of knowledge; and providing one output related to one or more partitions of the body of knowledge that are selected based on the evaluated value significances of the one or more partitions and/or one or more ontological subjects of the body of knowledge; 2. providing at least one cognitive graph from a body of knowledge by: identifying, using one or more data processing or computing devices, a plurality of ontological subjects of the body of knowledge based on their significance values and/or the association strength between at least two of the ontological subjects of the body of knowledge, and representing the identified ontological subjects graphically, by graphical objects and/or symbols and/or connecting at least two of the associated ontological subjects with graphical links based on their association strength to each other: 3. accessing to at least one pre-built body of knowledge which has been built in response to a client's request; and 4. providing a social interaction session for users looking for information related to similar or associated subject matters.
