Patent number: 9443005Abstract: Methods, systems and computer programs for automatic, highly accurate machine comprehension of a plurality of segments of free form unstructured text in a natural language. The system answers a plurality of complex, free-form questions asked in a natural language, based on the totality of input text. The system further uses a multi-dimensional data model to measure the total effects of actions/verbs acting on various unique nouns present in the input text. The system may convert the questions into another multi-dimensional data model and may then compare the two data models in program memory to derive the answers to the posed questions. The system may then automatically detect unknown words and optionally look them up in digital information sources, such as online dictionaries and encyclopedias, to fill in the gaps in knowledge to answer the questions with expert-like reliability.Type: GrantFiled: December 6, 2013Date of Patent: September 13, 2016Assignee: INSTAKNOW.COM, INC.Inventor: Pramod Khandekar

Patent number: 9426566Abstract: A voice signal processor detects background noise sections to reflect characteristics of the background noise on the Wiener filter coefficient to be used for suppressing noise components of input voice signals. In the voice signal processor, directivity signal generators form directivity signals having a directivity pattern. The directivity signals are used by a coherence calculator to obtain coherence, which is in turn used by a targeted voice section detector to detect a targeted voice section. A background noise section detector detects background noise sections containing no voice signal. When a background noise section is detected, a WF adapter uses characteristics of background noise in the detected temporal section to calculate a new WF coefficient.Type: GrantFiled: August 29, 2012Date of Patent: August 23, 2016Assignee: Oki Electric Industry Co., Ltd.Inventor: Katsuyuki Takahashi

Patent number: 9268769Abstract: A system, method, and computer program are provided for identifying message content to send to users based on the users' language characteristics. Language characteristics are extracted from user-generated content and language characteristic scores are assigned to each user. The users are clustered into groups using the language characteristic scores. The system sends test messages with different message content to at least a subset of each group's users and the response rates are measured. For each group, a message content to which the group is most responsive is identified and is associated with the group. Language characteristics from a new user's user-generated content are extracted and language characteristic scores are assigned to the new user. The group to which the new user belongs is identified using the new user's language characteristic scores. A message is sent to the new user with the message content previously associated with the identified group.Type: GrantFiled: December 14, 2012Date of Patent: February 23, 2016Assignee: Persado Intellectual Property LimitedInventors: Avishalom Shalit, Assaf Baciu, Guy Stephane Krief

Patent number: 9251133Abstract: According to one embodiment, approximate named-entity extraction from a dictionary that includes entries is provided, where each of the entries includes one or more words. Words are read from the entries of the dictionary, and network resources are searched to determine a frequency of occurrence of the words on the network resources. In view of the frequency of occurrence of the words located on the network resources, domain relevancy of the words in the entries of the dictionary is determined. A domain repository is created using top-ranked words as determined by the domain relevancy of the words. In view of the domain repository, signatures for both the entries of the dictionary and strings of an input document are computed. The strings of the input document are filtered by comparing the signatures of the strings against the signatures of the entries to identify approximate-match entity names.Type: GrantFiled: December 12, 2012Date of Patent: February 2, 2016Assignee: International Business Machines CorporationInventors: Ying Chen, William S.
