including: accessing communications data representing communications of processing the communications data to determine similarity data representing similarities between concepts expressed by the one or more persons at different times during said communications; and processing the similarity data to determine one or more metrics of said communications. ## Claims ### Claim 1 A communications analysis process, including: accessing communications data representing communications of one or more persons; processing the communications data to determine similarity data representing similarities between concepts expressed by the one or more persons at different times during said communications; and processing the similarity data to determine one or more metrics of said communications. ### Claim 2 (depends on 1) The process of claim 1, wherein the metrics include metrics for each of one or more selected utterances of said communications. ### Claim 3 (depends on 1) The process of claim 1, wherein the processing of the communications data includes: identifying subsets of said communications as utterances of said one or more persons; identifying terms of said utterances as representing conceptual content of said communications expressed by said one or more persons; selecting a subset of said terms as key terms representing respective concepts; generating numeric measures of the conceptual similarities of the unselected terms to said key terms; and for each of said utterances, generating a corresponding feature vector including the generated numeric measures of the terms included in the utterance to enable a similarity of any two of said utterances to be determined from the feature vectors for those two utterances. ### Claim 4 (depends on 1) The process of claim 1, wherein the metrics include a contribution metric representing the number of concepts of an utterance. ### Claim 5 (depends on 4) The process of claim 4, wherein the contribution metric is generated by summing concept scores for the utterance, said concept scores representing similarities of terms in the utterance to said concepts. ### Claim 6 (depends on 4) The process of claim 4, wherein the contribution metric is generated by summing the products of concept scores and transfer functions for the utterance, said concept scores representing similarities of terms in the utterance to said concepts. ### Claim 7 (depends on 1) The process of claim 1, wherein the metrics include an ownership metric representing the degree to which a person owns the content of an utterance. ### Claim 8 (depends on 7) The process of claim 7, wherein the ownership metric is generated by subtracting the similarity of the person's utterance and the previous utterance from the similarity of the person's utterance with itself. ### Claim 9 (depends on 1) The process of claim 1, wherein the metrics include an accommodation metric representing the degree to which a speaking person accommodates the immediately previous speaking person's utterance. ### Claim 10 (depends on 9) The process of claim 9, wherein the accommodation metric is generated as the similarity of the person's utterance and the previous speaker's utterance. ### Claim 11 (depends on 1) The process of claim 1, wherein the metrics include a leadership metric representing the degree to which a speaking person expressed a new concept that was subsequently repeated by one or more other persons. ### Claim 12 (depends on 11) The process of claim 11, wherein the leadership metric for an utterance of a person is generated by summing similarities of the utterance to one or more successive utterances by one or more other persons. ### Claim 13 (depends on 11) The process of claim 11, wherein the leadership metric for an utterance of a person is generated by summing similarities of the utterance to one or more successive utterances by one or more other persons, and then multiplying the sum by an ownership metric for the utterance. ### Claim 14 (depends on 1) The process of claim 1, wherein the metrics include a followership metric representing the degree to which a speaking person repeats the concepts expressed in preceding utterances by one or more other persons. ### Claim 15 (depends on 14) The process of claim 14, wherein the followership metric for an utterance is determined by summing the similarities of the utterance with every one or more preceding utterances by other people within a range of utterances from said utterance. ### Claim 16 (depends on 14) The process of claim 14, wherein the followership metric for an utterance is determined by summing the similarities of the utterance with every one or more preceding utterances by other people within a range of utterances from said utterance, and then multiplying the sum by an accommodation metric for the utterance. ### Claim 17 (depends on 1) The process of claim 1, wherein the metrics include an engagement metric representing how well the current utterance engages with concepts suggested by other speakers. ### Claim 18 (depends on 17) The process of claim 17, wherein the engagement metric for an utterance is determined by summing the similarities of every preceding and successive utterance by other people within a specified range of utterances from the utterance. ### Claim 19 (depends on 1) The process of claim 1, wherein the metrics include a fixation metric representing the degree to which a person repeats concepts. ### Claim 20 (depends on 19) The process of claim 19, wherein the fixation metric for an utterance is generated by summing the similarities of the utterance with every preceding and successive utterance by the same person within a specified range of utterances from the utterance. ### Claim 21 (depends on 1) The process of claim 1, wherein the metrics include an influence metric representing the degree to which the utterance introduces new concepts that are repeated in the future. ### Claim 22 (depends on 21) The process of claim 21, wherein the influence metric for an utterance is determined by summing the similarities of the utterance with every preceding utterance by a different person and subtracting this sum from the summed similarities of the utterance with every subsequent utterance by a different person within a specified range of utterances from the utterance. ### Claim 23 (depends on 1) The process of claim 1, wherein the metrics include a conformity metric representing the degree to which an utterance repeats previously and subsequently expressed concepts. ### Claim 24 (depends on 23) The process of claim 23, wherein the conformity metric is determined by summing the similarities of the utterance with every preceding and subsequent utterance by a different person within a specified range of utterances from the utterance. ### Claim 25 (depends on 1) The process of claim 1, wherein the metrics include a repetition metric representing the degree to which a person repeats their own concepts. ### Claim 26 (depends on 25) The process of claim 25, wherein the repetition metric is determined by summing the similarities of the utterance with every preceding and subsequent utterance by the same person within a specified range of utterances from the utterance. ### Claim 27 (depends on 1) The process of claim 1, including generating values of a plurality of metric primitives for each of said utterances of a corresponding person by summing the similarities of the utterance with one or more selected others of said utterances, said others for each of said metric primitives being selected as a corresponding unique combination of values specifying: (i) the range of utterances from the utterance within which other utterances can be selected; (ii) whether only other utterances following or only other utterances preceding the utterance can be selected; and (iii) whether only the person's own utterances can be selected or only utterances by others can be selected. ### Claim 28 (depends on 27) The process of claim 27, including generating behavioural metrics for one or more of said utterances by combining values of selected ones of the metric primitives. ### Claim 29 (depends on 27) The process of claim 27, including: generating normalised values of said metric primitives; and generating behavioural metrics for one or more of said utterances by combining values of selected ones of the normalised metric primitives. ### Claim 30 (depends on 1) The process of claim 1, including generating concept recurrence data representing a visual representation of said similarities during said human communications, including a chart with two axes representing utterances, and the similarity between any two utterances being represented visually at corresponding coordinates. ### Claim 31 (depends on 30) The process of claim 30, wherein the similarity between any two utterances is represented visually by colour and/or shading. ### Claim 32 (depends on 30) The process of claim 30, wherein each utterance is represented by a corresponding dimension representative of the length of the utterance. ### Claim 33 (depends on 1) A computer-readable storage medium having stored thereon programming instructions configured to cause at least one processor executing the stored programming instructions to execute the process of claim 1. ### Claim 34 (depends on 1) A communications analysis system configured to execute the process of claim 1. ### Claim 35 A communications analysis system, including one or more communications analysis components configured to: access communications data representing communications of one or more persons; process the communications data to determine similarity data representing similarities between concepts expressed by the one or more persons at different times during said communications; and process the similarity data to determine one or more metrics of said communications.
