Patents by Inventor Rajiv Srivastava

Rajiv Srivastava has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11755840
    Abstract: Extracting data from documents is challenging due to the variation in structure, content, styles across geographies and functional areas. Further complex relation types are characterized by one or more of N-ary entity mention arguments, cross sentence span of entity mentions for a relation mention, missing entity mention arguments and entity mention arguments being multi-valued. The present disclosure addresses these gaps in the art to extract entity mentions and relation mentions using a joint neural network model including two sequence labelling layers which are trained jointly. The mentions are extracted from documents to facilitate downstream processing. A first RNN layer creates sentence embeddings for each sentence in the document being processed and predicts entity mentions. A second RNN layer predicts labels for each sentence span corresponding to a relation type.

  • Patent number: 11061953
    Abstract: Embodiments of the present disclosure, implements method of extracting relevant sections from a plurality of documents by (a) receiving an input document from a user; (b) converting, the input document to a standard text file; (c) classifying, the standard text file to obtain a labelled text file associated with at least one cluster from a plurality of clusters; (d) extracting, from the labelled text file to obtain a plurality of relevant entities associated with at least one cluster in the plurality of clusters; (e) annotating, the standard text file by the extracted plurality of relevant entities to obtain an annotated enriched text file; (f) identifying, a plurality of section boundaries to obtain a sectioned data; and (g) extracting, relevant sections of the plurality of documents based on the plurality of relationship associated with the set of relevant entities.

  • Patent number: 10570162
    Abstract: A polymer material comprising a constraint bicyclic bridged structure such as bicyclo(2,2,1) ring system, most preferably a norbornyl group, pendant to a siloxane backbone. The bridged bicyclic-containing materials can exhibit good refractive index, transparency, gas permeability, and/or other properties making them suitable for use in a variety of applications.

  • Publication number: 20170161664
    Abstract: Systems and methods for replacement planning and management are provided. The method includes processing data specific to one or more users, identifying replacement for a predecessor in a particular position in an entity based on the data, identifying, one or more replacement patterns from replacement pattern datasets across platforms based on one or more attributes associated with the particular position. In an embodiment, one or more attributes may include at least one of records of the one or more users, one or more predecessor successor relationships specific to the particular position for a specified period. The method further includes generating one or more rules based on the identified replacement patterns and domain knowledge pertaining to the particular position, identifying successors across platforms from the one or more users based on the generated rules, and generate a list of plausible successors across platforms from the successors for replacement of the predecessor.
