Searching calls based on contextual similarity among calls

A system, comprising:

• a processor;
• and
• a memory storing computer-executable instructions that when executed by the processor cause the system to:
• receive a search query, wherein the search query specifies a first contact as a condition of a search;
• generate a first topic vector associated with the first contact, wherein the first topic vector representing a first context associated with the first contact, wherein the first topic vector is a multi-dimensional vector comprising dimensions that correspond to topic categories and likelihood values, wherein a likelihood value represents a relevance to a topic, and wherein the relevance is determined using a machine-learning model;
• identify, based on an angular distance of vectors including the first topic vector, a second contact in a contact content database, wherein the second contact includes a second topic vector representing a second context associated with the second contact;
• retrieve, based on the identified second contact, the contact, wherein the contact includes a speaker of the contact;
• and
• transmit the contact as a result of the search query.

A computer-implemented method, comprising:

• receiving a search query, wherein the search query specifies a first contact as a condition of a search;
• retrieving contact data associated with the first contact from a contact content database;
• generating, based on the contact data, a first topic vector associated with the first contact, wherein the first topic vector representing a context associated with the first contact, wherein the first topic vector is a multi-dimensional vector comprising dimensions that correspond to topic categories and likelihood values, wherein a likelihood value represents a relevance to a topic, and wherein the relevance is determined using a machine-learning model;
• identifying, based on an angular distance between the first topic vector and a second topic vector, a second contact as contextually similar to the first contact, wherein the second contact includes the second topic vector;
• retrieving at least part of recording associated with the identified second contact;
• and
• transmitting the at least part of recording as a result of the search query.
