Abstract: A method for following a topic in an electronic textual conversation, the method includes selecting, by a computing device, one or more primary terms related to a topic, sending, by the computing device, to at least one communication service, a first query containing the at least one primary term, receiving, by the computing device, from the at least one communication service, at least one first set of messages responsive to the first query, for each first set, extracting, by the computing device, from the first set of messages, a first plurality of additional terms, and for each term of the first plurality of additional terms, enumerating, by the computing device, the messages of the first set in which the term appears and adding the term to a list of secondary terms if the enumeration exceeds a threshold amount.

Abstract: Disclosed herein is a method and system for producing a term association vector space on demand for a client given a document set in electronic form. The method extracts terms from the document set, stripping out words that do not convey meaning and adding important phrases within the context of the document set to the terms. Associations between terms are calculated, subjected to further analytical processes, and collected in a matrix, whose rows are vectors defining the vector space. Additional associational data can be added by matrix arithmetic, and documents can be rendered as further vectors in the space.

Abstract: A system and related method are disclosed for searching a data set made up of a set of documents, a set of terms, and a vector associated with each term and each document. The method involves converting a search query to a vector in the vector space spanned by the term and document vectors, and combining vector-proximity searching and term searching to produce a set of results, which may be ranked according to various measures of relatedness to the query. Excerpts from each document in the result set may be displayed that contain the greatest term importance.
