  • Patent number: 11301518
    Abstract: Described herein are systems and methods for indexing document data in order to facilitate chemical structure searching. The document data may include chemical structure data corresponding to a chemical structure. Bit-screening data and connection data in the chemical structure data may be identified. The bit-screening data may correspond to constituent elements of the chemical structure, and the connection data may correspond to connections between the one or more constituent elements. A string tag may be generated based on a portion of the identified bit-screening data. The string tag may include an alphanumeric value for describing the chemical structure that corresponds to the chemical structure data. The document data may be indexed based on the string tag. The chemical structure data corresponding to a chemical structure in the document may be searchable based on correlating at least a portion of text data of a query with the indexed document data.

  • Patent number: 10572545
    Abstract: Described herein are systems and methods that efficiently search for documents related to chemical structures of interest to a user. In certain embodiments, text data and chemical structure data provided in a user query are simultaneously searched with a text-based search method to efficiently produce search results. Subsequent structure-based searching on the results of the text-based search produces precise results for a particular user query. This approach increases the speed of the structure-based search by reducing the amount of data the structure-based search searches over. Additionally described herein are systems and methods for indexing document data in order to facilitate this efficient searching.

  • Patent number: 9842151
    Abstract: The present disclosure provides a system and method for comprehensive data synchronization management between a sponsor-company's central electronic-laboratory-notebook system and either multiple contract-research-organizations or research sites. The system features a data loader server that can be deployed on-premise or in the cloud and allows scheduling of synchronization jobs of electronic-laboratory-notebook. The data loader software communicates to the contract research organization and the sponsor company's electronic laboratory notebook and executes scheduled or on-demand jobs. The data loader software may synchronized subsequent update of the data and may automatically delete the data from the contract research organization's site once a given transfer is complete. In some implementations, the method and system is configured for automation, scalability, and high-performance operations that focused on efficiency, security, configurability, and privacy/intellectual property protection.

  • Patent number: 7233891
    Abstract: A method, computer program product, and apparatus for parsing consecutive sentences which includes tokenizing the words of the sentence and putting them through an iterative inductive processor. The processor has access to at least a first and second set of rules. The rules narrow the possible syntactic interpretations for the words in the sentence. After exhausting application of the first set of rules, the program moves to the second set of rules. The program reiterates back and forth between the sets of rules until no further reductions in the syntactic interpretation can be made. Thereafter, deductive token merging is performed if needed.
