Patent number: 10803241Abstract: Systems and methods for text normalization in a plurality of noisy channels receive a text entry and channel origin data of the text entry; determine whether the text entry matches an in-vocabulary (IV) entry or whether the text entry is an out-of-vocabulary (OOV) entry; if the text entry is determined to have a matching IV entry, output the matching IV entry, and if the text entry is determined to be an OOV entry, implement a channel-specific error-type adapter framework based on the channel origin data, wherein the channel-specific error-type adapter framework is optimized for a specific channel from which the text entry originated; normalize the text entry using the channel-specific error-type adapter framework; and output one or more candidate normalized forms of the text entry.Type: GrantFiled: December 28, 2015Date of Patent: October 13, 2020Assignee: NICE LTD.Inventors: Hila Weisman, Peter Izsak, Inna Achlow, Victor Shafran

Patent number: 10089296Abstract: Systems and methods for sentiment lexicon expansion receive at least a domain specific corpus comprising a plurality of words, and a generic sentiment lexicon; parse the plurality of words in the domain specific corpus into a plurality of dependency relations; identify, using one or more syntactic dependency rules and at least one of the plurality of dependency relations, a set of one or more sentiment candidates in the domain specific corpus; filter from the set of one or more sentiment candidates any sentiment candidate having an expected performance below a predefined threshold; sample the filtered set of one or more sentiment candidates to be used in a qualitative evaluation; and, for each sentiment candidate that passes the qualitative evaluation, add the sentiment candidate to the generic sentiment lexicon.Type: GrantFiled: December 30, 2015Date of Patent: October 2, 2018Assignee: Nice Ltd.Inventors: Naomi Zeichner, Victor Shafran

Patent number: 9953048Abstract: A method for determining prominent keyphrases in interactions, comprising, receiving keyphrases of numerous interactions received via a plurality of channels that comprise apparatuses for conveying the interactions according to the media thereof, quantitatively evaluating each keyphrase by a plurality of different metrics thereby yielding a corresponding plurality of values, and linearly combining the plurality of the values with a corresponding plurality of coefficients associated with a channel via which an interaction having said keyphrase is received, thereby providing a score of said keyphrase, and based on a condition related to the scores of the keyphrases, selecting at least one keyphrase as an at least one prominent keyphrase, wherein the method is at least partially performed by an at least one computerized apparatus configured for interfacing with the apparatuses of the plurality of the channels.Type: GrantFiled: March 5, 2015Date of Patent: April 24, 2018Assignee: NICE LTD.Inventors: Hila Weisman, Peter Izsak, Victor Shafran

Publication number: 20120158772Abstract: Implementations of the present disclosure include methods for generating structured service descriptions corresponding to one or more enterprise services. In some implementations, methods include defining a unified schema based on a governance process that is used to develop enterprise services stored within a business service repository, executing a first data importer and a second data importer, retrieving first data and second data from the business service repository using the first data importer and the second data importer, respectively, the first data and the second data corresponding to the enterprise services, automatically generating structured service descriptions based on the first data and the second data, each of the structured service descriptions corresponding to the unified schema and being associated with one of the enterprise services, and storing the structured service descriptions in a service repository, the service repository being provided in a computer-readable storage medium.Type: ApplicationFiled: December 20, 2010Publication date: June 21, 2012Applicant: SAP AGInventors: Victor Shafran, Eliezer Levy, Michael Stollberg
