摘要:
Systems, methods, and other embodiments associated with extracting attributes from electronic data structures are described. In one embodiment, a method includes correlating tokens from description strings with defined attributes in an electronic inventory database by identifying which of the defined attributes match the tokens to link the tokens with columns of the database associated with the defined attributes. The method includes iteratively updating annotation strings for unidentified ones of the tokens by generating suggested matches for the unidentified tokens according to known correlations between identified tokens and the defined attributes using a conditional random fields model. The method also includes populating the database using the identified tokens from the description strings according to the annotation strings by automatically storing the tokens from the description strings into the columns as identified by the annotation strings.

Techniques and constructs that improve annotating target columns of a target database by performing automated annotation of the target columns using sources. The techniques include calculating a similarity score between a target column and columns extracted from a table that is included in a source. The similarity score is calculated based at least in part on a similarity between a value in the target column of the target database and a column value of the extracted column from the table and on a similarity between an identity of the target column of the target database and column identities of the extracted columns from the table. In some examples, the techniques calculate similarity scores for one or more extracted columns and annotate the target column based on the similarity scores.

Systems, methods, and related technologies for application-centric object storage are described. In certain aspects, a processing device can receive, from an application, one or more requests with respect to a data object, process the requests to determine one or more data utilization characteristics of the application with respect to the data object, and configure one or more aspects of the data object in view of the one or more data utilization characteristics. In other aspects, a processing device can process a first data object in a first format to generate a virtual data object that corresponds to a representation of the first data object in a second format, receive a request with respect to the first data object from an application that is configured with respect to the second format, and complete the request with respect to the first data object and the application via the virtual data object.
摘要:
A content providing method and an electronic apparatus performing the content providing method are provided. The content providing method includes acquiring at least one content item from a content provider, extracting at least one tagged value from each of the at least one user content item, producing a tag list, based on the extracted at least one tagged value, and searching for content of interest by using the at least one tagged value included in the tag list.
摘要:
Methods, systems, computer-readable media, and apparatuses for providing search disambiguation using contextual information and domain ontologies are presented. In some embodiments, a computing device may receive a natural language input from a user. The computing device may identify a plurality of hypotheses for the natural language input. The computing device may map the plurality of hypotheses to one or more concepts of a plurality of concepts of an ontology by annotating the one or more concepts. The ontology may include the plurality of concepts respectively connected by a plurality of relations. The computing device may determine that there is an imperfect match between the annotated one or more concepts and annotations of answers. In response, the computing device may disambiguate the annotated one or more concepts using the ontology. The computing device may present output to the user based on the disambiguation.

Gesture based interactive graphical user interface for video style editing on smartphone or camera with touchscreen. A method and apparatus for editing video and changing video effects on a mobile device. The system permits a user to alter video effects on a mobile device through use of gestures. A hierarchical editing is foreseen, with a first level such as color tone, brightness, and a second level such as edit-theme or edit-style. As the user changes the video effects though gestures, the changes are simultaneously applied to the video providing graphical feedback to the user.

摘要:
A system, in particular a medical information system, for executing queries to a connected data source (120) storing information in an RDF compatible format and using preset first concepts comprises - an inputting means (130) for receiving a semantic query (300) from a user, wherein the semantic query (300) includes predefined second concepts of a specific user terminology; - a processing means (110) comprising a converter module (114) for converting the semantic query (300) received from the inputting means (130) into a data- base query using query language adapted for the RDF compatible format and including the first concepts, and searching the connected data source (120) by executing the database query; and - an outputting means (140) for outputting the search results (380) retrieved from the connected data source (120) by the processing means (110). By means of the invention it is possible to carry out efficient database searches based on semantic queries using a specific user terminology with reduced processing power and time.
