Abstract: This disclosure relates generally to long-form answer extraction and, more particularly, to long-form answer extraction based on combination of sentence index generation techniques. Existing answer extractions techniques have achieved significant progress for extractive short answers; however, less progress has been made for long form questions that require explanations. Further the state-of-art long-answer extractions techniques result in poorer long-form answers or not address sparsity which becomes an issue longer contexts. Additionally, pre-trained generative sequence-to-sequence models are gaining popularity for factoid answer extraction tasks. Hence the disclosure proposes a long-form answer extraction based on several steps including training a set of generative sequence-to-sequence models comprising a sentence indices generation model and a sentence index spans generation.

Abstract: Conventional Question and Answer (QA) datasets are created for generating factoid questions only and the present disclosure generates longform technical QA dataset from textbooks. Initially, the system receives a technical textbook document and extracts a plurality of contexts. Further, a first plurality of questions are generated based on the plurality of contexts. A plurality of answerable questions are generated further based on the plurality of contexts using an unsupervised template-based matching technique. Further, a combined plurality of questions are generated by combining the first plurality of questions and the plurality of answerable questions. Further, an answer for the combined plurality of questions are generated using an autoregressive language model and a mapping score is computed. Further, a plurality of optimal answers are selected based on the corresponding mapping score.

Abstract: A remote computer access facility uses two dedicated computers outside the firewall. To ensure security the system makes use of biometrics features and a one-time password mechanism on top of secure socket layer (SSL) to authenticate a user. The system also provides three layers of security levels for transmission. The first layer establishes an SSL connection, the second layer periodically asks for a one-time password (OTP), and the third layer uses any kind of conventional encryption. The combination of the biometric, OTP and encryption key forms a strong password. The system also uses a mechanism for secure file accesses within the organization based on the security privileges assigned to various users. Based on the user's access privileges, the server side software module sends the requested file in an encrypted form along with the key to decrypt that file—this key is encrypted by the user's strong password.

Abstract: In some embodiments, systems and methods for visually rendering images rotate images at time of display based on annotations indicating needed rotations. In other embodiments, systems and methods for visually rendering images rotate images at time of display by determining a needed rotation for an image based on automatic orientation recognition. In further embodiments, systems and methods for visually rendering images rotate images at time of display by utilizing fuzzy logic to determine a best rotation angle for an image based on a none precise marking generated by computer vision or signal processing applied to the image. In yet further embodiments, systems and methods for annotating images annotate images at time of image capture, time of image display, or any time in between by using one or more of automatic image orientation recognition, user input specifying a needed rotation, and sensed orientation of an image capture mechanism.

Abstract: A method and system for providing access to a data file enables predetermination of the number of times the file is accessible. The data file is encrypted with a master key, and one or more dual-encrypted blocks are generated based on a set of secondary keys. The dual-encrypted blocks are contained within the encrypted data file. The method further provides for providing the encrypted data file and an attachment file to an authorized user, where the attachment file enables a device to access the data file content once for each secondary key. The file is accessed by decrypting single-encrypted blocks of the data file with a master key. Dual-encrypted blocks of the data file are decrypted with the master key and a secondary key. The decryption steps are repeated for a set of secondary keys such that the device is able to access the data file content once for each secondary key in the set.
