The method includes a step A of collecting data from a general web that is accessible through a search engine; a step B of collecting data from a dark web site that is not accessible with a general web browser and is accessible with preset specific software; and a step C of standardizing the collected data in a preset format and generating metadata for the collected data.

Abstract: Computer implemented methods, systems, and computer program products include program code executing on a processor(s) that obtains a user query. The program code selects just in time (JIT) statistics relevant for use by a cost optimizer to generate a plan file for executing the user query by determining, based on JIT metadata in a JIT statistics cache, if JIT statistics generated responsive to an earlier event are these JIT statistics, and based on determining that the JIT statistics generated responsive to the earlier event are these JIT statistics, selects these JIT statistics to generate the plan file. The program code utilizes the cost optimizer to generate the plan file based on these JIT statistics. The program code executes the user query in the target database based on the plan file.

Abstract: In some aspects, the disclosure is directed to methods and systems for secure and authenticated tracking of entity possession via a lightweight centralized or distributed ledger. Ownership records of different entities may be recorded on an immutable ledger such that provenance of the entities is verifiable and a user cannot create or counterfeit an entity. In some implementations, the system may store metadata of entities in a separate database that may store records for each entity and correspond to the respective entity's virtual identifier, enabling the ledger records to contain much less data, saving memory resources and the energy that is required to maintain the ledger. In some implementations, distributed incremental values may be provided to members of an ownership or possession chain of an entity, which may encourage compliance, reporting of ownership transfer, and encourage additional transfers.

Abstract: Methods, systems, and computer-readable storage media for data replication. Data records associated with business entities are obtained. A plurality of data fields is defined for each record. A first set of data records is determined as associated with a first identifier of a first business entity. Data from a first set of data fields is selected from each data record of the first set of the data records. The first set of data fields are a subset of the plurality of data fields and is defined for evaluation of the first set of data records associated with the first business entity to determine a first data record from the first set of data records to be replicated from the data management system into a database system.

Abstract: Methods, systems, and non-transitory computer readable storage media are disclosed for optimizing computer memory usage for lookup lists in computer memory via probabilistic data structures. For example, the disclosed system generates a probabilistic data structure (e.g., a Bloom filter) to represent data in a lookup list including multi-token items by hashing items of the lookup list to sets of bit values in a bit vector. The disclosed system classifies text content in a digital document by utilizing a maximum number of tokens from multi-token items in the lookup list to select and compare sets of sequential tokens in the digital document to the probabilistic data structure. The disclosed system also iteratively reduces the number of tokens in sets of sequential tokens for subsequent comparisons. Furthermore, in some aspects, the disclosed system causes a computing device to modify a digital document and/or database operations based on the classifications.

Abstract: Embodiments are disclosed for a digital design system trained to segment unstructured text into topically coherent segments. The method may include receiving unstructured text, the unstructured text including a sequence of sentences. The disclosed systems and methods further comprise generating, by a neural network, a hierarchically segmented tree structure representing the unstructured text. The tree structure comprises a plurality of tree structure nodes, where a node of the tree structure nodes represents a sentence from the sequence of sentences. The segments and sub-segments of the unstructured text can then be determined based on node data for nodes of the hierarchically segmented tree structure. Using the determined segments and sub-segments of the unstructured text, a modified representation of the unstructured text can be displayed.

Abstract: Systems and methods for cloud-based file sharing, where templates are provided for creating workflow instances which enable the sharing of managed objects. Reusable workflow templates are stored in the repository of a cloud-based file sharing system as objects that define components of the workflow, or placeholders for these components. A user instantiates a workflow instance from one of the templates and configures the workflow instance to identify content objects or forms, tasks related to the content objects, and users assigned to perform the tasks. The workflow instance is stored as an object in the repository. Users assigned to tasks are authorized through the workflow instance to access the content objects or forms to perform the tasks.

Abstract: Methods, systems, and computer program products are provided for creating a resource management testing environment. An initial population of databases is established in a database ring, having an in initial count of databases and different types of databases that are determined based on an initial database population model. The initial population model receives ring classification information for the database ring from a ring grouping model. A sequence of database population-change events is generated based on a model, to change the population of the databases over time in the ring. An orchestration framework performs testing of resource manager operations based on the model-defined initial population of databases and the model-defined populations of databases changed over time. Model-defined resource usage metrics for each database are utilized to test the resource manager operations. Resource usage metrics and database add/drop events of a production system are used to train the models.

Abstract: Actions are performed on data in databases of a multi-node system. Each node includes an indicia engine and each node has access to a respectively associated database. Each of the databases has a first subset of data that match each other and which are kept in synchronization with each other. At least one of the databases has a second subset of data that intentionally does not match a subset of data in at least one of the other databases and which is not kept in synchronization with the at least one of the other databases. In operation, each node receives a plurality of matching requests to perform an action on data in the database associated with each node. The indicia engine at each node computes, for each of the matching requests, indicia of results of the action performed on data in the database associated with each node.

According to an embodiment, a query execution method includes: generating snippets for offloading a part of query computations for a query received from a client to CSDs; scheduling the generated snippets for the CSDs; collecting results of offloading; and merging the collected results of offloading. Accordingly, by dividing query computations, offloading, and processing in parallel, while processing query computations that are inappropriate for offloading by a DBMS, a query request from a client can be executed effectively and rapidly.

Abstract: A system and method for saving and restoring snapshots of a client device connected to a virtual desktop are disclosed. When a client device makes a request to capture the state of the virtual desktop, the request is sent to a server if the client device and virtual desktop are authorized according to a policy. The request may also specify that the virtual desktop's memory contents be captured. The server forms the snapshot and saves the snapshot in storage. When a client device makes a request to restore the virtual desktop, the client selects one of the saved snapshots and restores the virtual desktop, including its memory, when the client device and desktop are authorized, and the snapshot has not exceeded its allowed time in storage according to the policy.
