Patent number: 11755885Abstract: A system, method and computer program product for disambiguating one or more entity mentions in one or more documents. The method facilitates the simultaneous linking entity mentions in a document based on convolution neural networks and recurrent neural networks that model both the local and global features for entity linking. The framework uses the capacity of convolution neural networks to induce the underlying representations for local contexts and the advantage of recurrent neural networks to adaptively compress variable length sequences of predictions for global constraints. The RNN functions to accumulate information about the previous entity mentions and/or target entities, and provide them as the global constraints for the linking process of a current entity mention.Type: GrantFiled: April 6, 2020Date of Patent: September 12, 2023Assignee: International Business Machines CorporationInventors: Nicolas R. Fauceglia, Alfio M. Gliozzo, Oktie Hassanzadeh, Thien H. Nguyen, Mariano Rodriguez Muro, Mohammad Sadoghi Hamedani

Patent number: 11138523Abstract: A method, system and computer-usable medium are disclosed for reducing labeled data imbalances when training an active learning system. The ratio of instances having positive labels or negative labels in a collection of labeled instances associated with an input category used for learning is determined. A first instance for annotation is selected from a collection of unlabeled instances if a first threshold for negative instances, and a first threshold confidence level of being a positive instance of the input category, have been met. A second instance for annotation is selected if a second threshold for positive instances, and a second threshold confidence level of being a negative instance of the input category, have been met. The first and second instances are respectively annotated with a positive and negative label and added to the collection of labeled instances, which are then used for training.Type: GrantFiled: July 27, 2016Date of Patent: October 5, 2021Assignee: International Business Machines CorporationInventors: Md Faisal M.

Patent number: 10579729Abstract: Embodiments are directed to a spellcheck module for an enterprise search engine. The spellcheck module includes a candidate suggestion generation module that generates a number of candidate words that may be the correction of the misspelled word. The candidate suggestion generation module implements an algorithm for indexing, searching, and storing terms from an index with a constrained edit distance, using words in a collection of documents. The spellcheck module further includes a candidate suggestion ranking module. In one embodiment, a non-contextual approach using a linear combination of distance and probability scores is utilized; while in another embodiment, a context sensitive approach accounting for real-word misspells and adopting deep learning models is utilized. In use, a query is provided to the spellcheck module to generate results in the form of a ranked list of generated candidate entries that may be an entry a user accidentally misspelled.Type: GrantFiled: October 18, 2016Date of Patent: March 3, 2020Assignee: International Business Machines CorporationInventors: Alfio M.

Patent number: 10282421Abstract: Embodiments provide a system and method for short form and long form detection. Using a language-independent process, the detection system can ingest a corpus of documents, pre-process those documents by tokenizing the documents and performing a part-of-speech analysis, and can filter one or more candidate short forms using one or more filters that select for semantic criteria. Semantic criteria can include the part of speech of a token, whether the token contains more than a pre-determined amount of symbols or digits, whether the token appears too frequently in the corpus of documents, and whether the token has at least one uppercase letter. The detection system can detect short forms independent of case and punctuation, and independent of language-specific metaphone variants.Type: GrantFiled: June 29, 2018Date of Patent: May 7, 2019Assignee: International Business Machines CorporationInventors: Md Faisal M.

Patent number: 10275454Abstract: According to an aspect, a term saliency model is trained to identify salient terms that provide supporting evidence of a candidate answer in a question answering computer system based on a training dataset. The question answering computer system can perform term saliency weighting of a candidate passage to identify one or more salient terms and term weights in the candidate passage based on the term saliency model. The one or more salient terms and term weights can be provided to at least one passage scorer of the question answering computer system to determine whether the candidate passage is justified as providing supporting evidence of the candidate answer.Type: GrantFiled: October 13, 2014Date of Patent: April 30, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Md Faisal Mahbub Chowdhury, Alfio M.

Publication number: 20180365210Abstract: Embodiments provide a system and method for short form and long form detection. Given candidate short forms, the system can generate one or more n-gram combinations, resulting in one or more candidate short form and n-gram combination pairs. For each candidate short form and n-gram combination pair, the system can calculate an approximate string matching distance, calculate a best possible alignment score, calculate a confidence score, calculate a topic similarity score, and calculate a semantic similarity score. The system can determine the validity, through a meta learner, of the one or more valid candidate short form and n-gram combination pairs based upon each short form and n-gram combination pair's confidence score, topic similarity score, and semantic similarity score, and store the valid short form and n-gram combination pairs in a repository. The system has no language specific constraints and can extract short form and long form pairs from documents written in various languages.Type: ApplicationFiled: August 22, 2018Publication date: December 20, 2018Inventors: Md Faisal M.

Publication number: 20180032901Abstract: A method, system and computer-usable medium are disclosed for reducing user interaction when training an active learning system. Source input containing unlabeled instances and an input category are received. A Latent Semantic Analysis (LSA) similarity score, and a search engine score, are generated for each unlabeled instance, which in turn are used with the input category to rank the unlabeled instances. If a first threshold for negative instances has been met, a first unlabeled instance, having the highest ranking, is selected for annotation from the ranked collection of unlabeled instances and provided to a user for annotation with a positive label. If a second threshold for positive instances has been met, then second unlabeled instance, having the lowest ranking, is selected for annotation from the ranked collection of unannotated instances and automatically annotated with a negative label. The annotated instances are then used to train an active learning system.Type: ApplicationFiled: July 27, 2016Publication date: February 1, 2018Inventors: Md Faisal M.
