Patent number: 11357431Abstract: Methods and apparatus to identify an emotion evoked by media are disclosed. An example apparatus includes a synthesizer to generate a first synthesized sample based on a pre-verbal utterance associated with a first emotion. A feature extractor is to identify a first value of a first feature of the first synthesized sample. The feature extractor to identify a second value of the first feature of first media evoking an unknown emotion. A classification engine is to create a model based on the first feature. The model is to establish a relationship between the first value of the first feature and the first emotion. The classification engine is to identify the first media as evoking the first emotion when the model indicates that the second value corresponds to the first value.Type: GrantFiled: October 16, 2020Date of Patent: June 14, 2022Assignee: The Nielsen Company (US), LLCInventors: Robert T.

Patent number: 10970291Abstract: Provided are systems, methods, and devices for providing topical similarities in a knowledge database. A knowledge database containing a number of articles is accessed, and clickstream data for the knowledge database is obtained including aggregated counts of user clicks on links within articles in the knowledge database. The clickstream data is sorted by source article, with each source article corresponding to a number of target articles that the source article links to. A directed article graph is constructed based on the sorted clickstream data. An input search term is received from an input device, and then an unbounded graph search is performed on the directed graph based on the input search term. Finally, a ranking heuristic for a predefined number of articles in the knowledge database is provided corresponding to topical similarity of the articles to the input search term.Type: GrantFiled: October 19, 2018Date of Patent: April 6, 2021Assignee: MACHINEVANTAGE, INC.Inventors: Daniel Martin McNeela, Ratnakar Dev, Anantha K.

Patent number: 10915707Abstract: Provided are systems, methods, and devices for providing word replaceability information through word vectors. Within a database system, a text document is received, then processed into a number of sub-sentences or sub-segments. The processing involved delimiting one or more sentences within the text document by one or more punctuation marks. Next, a number of n-gram combinations are generated according to co-appearances of n-grams within the sub-sentences. Distance metrics are determined between the n-gram co-appearances for each n-gram combination. Finally, word replaceability information is provided for one or more words or n-grams within the text document, based on the distance metric.Type: GrantFiled: October 19, 2018Date of Patent: February 9, 2021Assignee: MACHINEVANTAGE, INC.Inventors: Peter Taraba, Ratnakar Dev, Anantha K.

Patent number: 10853578Abstract: Provided are systems, methods, and devices for extracting unconscious meaning from media corpora. One or more corpora are received from one or more media databases. A number of phrases are extracted from the corpora, and then disambiguated according to natural language processing methods. One or more criteria are then selected to be used for phrase analysis, and the phrases are then analyzed to extract unconscious meaning based on the one or more criteria. The phrase analysis involves machine learning or predictive analysis methods. The results of the phrase analysis are then provided to one or more client devices, with the results containing findings of unconscious meaning for the phrases.Type: GrantFiled: October 19, 2018Date of Patent: December 1, 2020Assignee: MACHINEVANTAGE, INC.Inventors: Ratnakar Dev, Anantha K.
