A method of extracting mathematical concepts from mathematical exercise representations includes the steps of accessing at least one document including a plurality of mathematical exercise representations, wherein each mathematical exercise representation comprises one or more algorithmic, linguistic, geometric, and graphic mathematical exercise representations; extracting each mathematical exercise representation to identify one or more mathematical concepts; identifying a relationship between a first mathematical concept and a second mathematical concept to identify a plurality of concept groups; populate an optimization table to associate at least one of the mathematical concepts and concept groups with one or more of the plurality of mathematical exercise representations; and optimize the optimization table to remove redundancies.

Systems, methods and computer program products for using searchable aggregate indices associated with non-aggregated value storage. In one method, a search system stores metadata values for each of a plurality of objects in a storage unit. The metadata values are stored in corresponding value storage locations that are associated with an identifiable metadata fields. An aggregate index is provided which includes a dictionary of terms that are contained in metadata values associated with a designated set of the metadata fields. The aggregate index is searched for one or more specific search terms, and one or more of the metadata values are retrieved from the value storage locations in response to the search, where the individual metadata fields associated with the retrieved metadata values are identified.

A database management system for processing large volumes of data in a key-value store database is provided. The system may be configured to receive a plurality of filled fillable request forms where each request form may include a request including a plurality of field labels and a plurality of fillable text fields corresponding to each of the plurality of the field labels. The system may be configured to extract each set of inputted data from each fillable text field. The system may be configured to store, in the key-value store database, for each request form, each of the plurality of field labels and the corresponding set of inputted data as a combination key-value pair. The combination key may be equal to a WIP ID number, form ID number and field ID number. The corresponding value may be equal to the set of data of the corresponding field ID number.

A semantic indexing system, the semantic indexing system comprising a processing resource configured to: provide a corpus comprising a plurality of textual documents, wherein (a) each of the textual documents being composed of one or more sentences; (b) each of the sentences being composed of one or more statements; and generate an index, the index mapping each of the statements to one or more frames; wherein each frame defines a structure that carries a semantic meaning, thereby enabling searching the corpus by the semantic meaning of a search statement.

There is provided a system including a memory and a processor configured to obtain a first frame of a video content including an object and a first region based on a segmentation hierarchy of the first frame, insert a synthetic object into the first frame, merge an object segmentation hierarchy of the synthetic object with the segmentation hierarchy of the first frame to create a merged segmentation hierarchy, select a second region based on the merged segmentation hierarchy, provide the first frame including the first region and the second region to a crowd user for creating a corrected frame, receive the corrected frame from the crowd user including a first corrected region including the object and a second corrected region including the synthetic object, determine a quality based on the synthetic object and the second corrected region, and accept the first corrected region based on the quality.

There is provided a system including a memory and a processor configured to obtain a first frame of a video content including an object and a first region based on a segmentation hierarchy of the first frame, insert a synthetic object into the first frame, merge an object segmentation hierarchy of the synthetic object with the segmentation hierarchy of the first frame to create a merged segmentation hierarchy, select a second region based on the merged segmentation hierarchy, provide the first frame including the first region and the second region to a crowd user for creating a corrected frame, receive the corrected frame from the crowd user including a first corrected region including the object and a second corrected region including the synthetic object, determine a quality based on the synthetic object and the second corrected region, and accept the first corrected region based on the quality.

A method for searching encrypted data includes identifying, with a client, a plurality of values within a predetermined search range in a search index stored within a memory of the client, each value in the plurality of values being present in a plaintext representation of at least one encrypted file in a plurality of encrypted files stored in a server. The method further includes generating and transmitting at least one search query to the server through a data network, and receiving, with the client, at least one response from the server through the data network, the response including the encrypted keyword corresponding to the value in the plurality of values and an identifier of at least one file in the plurality of encrypted files stored on the server that includes the value.

Provided are a database (DB) managing method and system, wherein, while forming an index of a DB, a lower value and an upper value of key values of a plurality of records included in one page are stored as separators and an overlapping part of the key values is deleted from the plurality of records by using the separators to save a storage space where pages of the index is stored, and thus the performance of the DB is improved.

Provided are systems and methods for managing storage of machine data. In one embodiment, a method can be provided. The method can include receiving, from one or more data sources, raw machine data; processing the raw machine data to generate processed machine data; storing the processed machine data in a data store; and determining an allocated data size associated with the processed machine data stored in the data store, wherein the allocated data size is the size of the raw machine data corresponding to the processed machine data stored in the data store.

A written document (hereinafter referred to as a work, on electronic format which includes, stories, novels, education texts, biographies, compilations, collections, anthologies, tracts, and any other traditional format for relatively extensive texts) provides access to reference, bibliography and/or definition material through an electronic software capability associated with the work. Depending upon reader access information or characteristics (e.g., age, grade, proficiency, or position within the work or any other identifiable reader characteristic or access limitation), any request for reference material, definitions, explanations, translations, or other material provided in the associated software capability is automatically limited by system acknowledgement of the reader access information or characteristics. As the reader's access information or characteristics change, the quality and/or quantity and/or format of requested information with respect to a work changes.
