Patent number: 11328121Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for collecting web data in order to create diverse language models. A system configured to practice the method first crawls, such as via a crawler operating on a computing device, a set of documents in a network of interconnected devices according to a visitation policy, wherein the visitation policy is configured to focus on novelty regions for a current language model built from previous crawling cycles by crawling documents whose vocabulary considered likely to fill gaps in the current language model. A language model from a previous cycle can be used to guide the creation of a language model in the following cycle. The novelty regions can include documents with high perplexity values over the current language model.Type: GrantFiled: August 7, 2017Date of Patent: May 10, 2022Assignee: Nuance Communications, Inc.Inventors: Luciano De Andrade Barbosa, Srinivas Bangalore

Patent number: 10114818Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for bootstrapping a language translation system. A system configured to practice the method performs a bidirectional web crawl to identify a bilingual website. The system analyzes data on the bilingual website to make a classification decision about whether the root of the bilingual website is an entry point for the bilingual website. The bilingual site can contain pairs of parallel pages. Each pair can include a first website in a first language and a second website in a second language, and a first portion of the first web page corresponds to a second portion of the second web page. Then the system analyzes the first and second web pages to identify corresponding information pairs in the first and second languages, and extracts the corresponding information pairs from the first and second web pages for use in a language translation model.Type: GrantFiled: October 17, 2016Date of Patent: October 30, 2018Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Luciano De Andrade Barbosa, Srinivas Bangalore, Vivek Kumar Rangarajan Sridhar

Patent number: 10032118Abstract: A system that incorporates teachings of the present disclosure may operate, for example, obtaining a number of blogs including an initial set of annotated blogs and unannotated blogs. The initial set of annotated blogs are annotated as being either relevant to a selected media program or not relevant to the selected media program. A set of features is determined associating the selected media program with the unannotated blogs and a trained classifier is generated based on the set of features. The trained classifier is applied to the blogs to identify a subset of blogs relevant to the selected media program. An analysis is performed on the selected blogs to determine a trend related to the selected media program and a graphical user interface is presented that concurrently presents the selected blogs, the trend, and the selected media program. Other embodiments are disclosed.Type: GrantFiled: February 15, 2016Date of Patent: July 24, 2018Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Junlan Feng, Luciano De Andrade Barbosa, Hisao Chang, Bernard S.

Patent number: 9659248Abstract: Determining semantically equivalent text or questions using hybrid representations based on neural network learning. Weighted bag-of-words and convolutional neural networks (CNN) based distributed vector representations of questions or text may be generated to compute the semantic similarity between questions or text. Weighted bag-of-words and CNN based distributed vector representations may be jointly used to compute the semantic similarity. A pair-wise ranking loss function trains neural network. In one embodiment, the parameters of the system are trained by minimizing a pair-wise ranking loss function over a training set using stochastic gradient descent (SGD).Type: GrantFiled: January 19, 2016Date of Patent: May 23, 2017Assignee: International Business Machines CorporationInventors: Luciano de Andrade Barbosa, Daria Bogdanova, Matthias Kormaksson, Cicero Nogueira dos Santos, Bianca Zadrozny
