A structured natural language query and knowledge system is provided to allow a user who lacks programming skills to enter a database query or a rule in the form of a structured natural language sentence. The scope of the sentence is preferably defined by an improved object relational query language, an object relational algebra, or both. Command and conditions that appear in natural language form are defined with corresponding formal query texts. A user is prompted to compose a structured natural language sentence using the defined commands and conditions. The user-selected command and its arguments appear as the verb phrase of a structured natural language sentence. The user-selected conditions and their parameters appear as the adjective phrases of the sentence. The sentence is parsed and changed into a translated formal query text for formal database query and rule processing.

A method of transforming relational queries of a database into on a data processing system includes receiving a series of relational queries, transforming first parts of the queries into a continuous query embodied as a streaming application, sending parameters in second parts of the queries in the series to the streaming application as a data stream, and executing the continuous query based on the received data stream to generate query results for the series of relational queries. Each query in the series includes a first part and a second part. The first parts are a pattern common to all the queries in the series and the second parts each have one or more parameters that are not common to all of the queries in the series.

A system and/or methodology that employs a non-relational (e.g., XML (extensible markup language)) query language to access stored procedures employed in connection with relational (e.g., SQL (structured query language)) database management systems is provided. Stored procedures in SQL enable the predetermination of queries that can be executed against the relational database. The invention bridges the gap between non-relational query languages and relational data stores. In other words, the invention enables the integration of non-relational query languages with relational data stores. The invention can define a view of the relational data in the current data model, convert data from relational to non-relational format and provide a mechanism in which a stored procedure can be referenced from the non-relational query language, using, for example, a function.

Certain example embodiments concern a computer-implemented method of processing a relational query in a database system. The relational query addresses a plurality of data objects linked by one or more relationships. For each data object addressed by the relational query, at least one result is computed in accordance with at least one index structure, with the index structure being stored in a storage device of the database system. The results computed are merged in accordance with at least one translation data structure to produce a final result of the relational query, with the translation data structure representing the one or more relationships between the data objects and being stored in a memory of the database system.

An XML wrapper queries an XML document in an on-the-fly manner so that only parent nodes in the document that satisfy the query are extracted and then unnested. The parent nodes and associated descendent nodes are located using XPath expressions contained as options in data definition language (DDL) statements. The parent nodes satisfying the query and associated descendent nodes are extracted and stored outside of a database according to a relational schema. The wrapper facilitates applications that use convention SQL queries and views to operate on that information stored according to the relational schema. The wrapper also responds to query optimizer requests for costs associated with queries against external data sources associated with the wrapper.

The invention discloses a method, device and method for querying order relations. The method comprises the following steps: responding to an order relation query request from a query requester and searching for a preset buffer which is used for storing all or partial order relations in an order relation database; if an entry matching identification information carried by the query request is searched in the preset buffer, returning the searched entry to the query requester; or, obtaining the order relation corresponding to the identification information from the order relation database and returning the order relation to the query requester, wherein the order relation database stores all the order relations. The required order relations are provided to the query requester of the order relations by setting the buffer which stores the order relations, thus the invention solves the problem that the system performances are affected because the query is slow and the query process increases the load of the system in the related arts, and can effectively improve the query efficiency.

An object oriented query such as an enterprise java bean query is translated into a corresponding relational query by identifying an inter-hierarchal relationship relating two or more object oriented hierarchies; identifying a source object oriented hierarchy of the inter-hierarchal relationship; mapping the source object oriented hierarchy into corresponding source relational tables; building a source series of joins between the source relational tables, the source series being ordered in a top-down order from a root of the source object oriented hierarchy; identifying a target class of the inter-hierarchal relationship; mapping the target object oriented hierarchy into corresponding target relational tables; building a target series of joins between the target relational tables, the target series comprising a first target series and a second target series, the first target series corresponding to the target class, a root of the target object oriented hierarchy, and intervening nodes between the target class and the root of the target object oriented hierarchy, and the second target series corresponding to nodes in leaves of the target object oriented hierarchy located below the target class; and combining the source series of joins and the target series of joins into the corresponding relational query. For a query selection based upon a plurality of relationships between the object oriented hierarchies, the steps may be repeated for each of the plurality of relationships. The combined series of joins may be further reordered by recursively finding a join relationship between a current node and a preceding node in the combined series of joins. To improve performance, a join above a target of a relationship is built as an inner join, and a join below the target of relationship is built as an outer join.

The invention discloses a sample knowledge graph relation learning method and system based on an adversarial attention mechanism. The method comprises: obtaining relation triples in a target knowledgegraph and natural text description corresponding to the relation triples; performing representation learning on the target knowledge graph to obtain vector representation of a triple; performing linedrawing representation learning on the text corresponding to the triple to obtain word vector representation in the text; constructing a conditional adversarial generation network with a denoising attention module and a confusion attention module; and performing optimization training on the conditional adversarial generation network, and predicting a target entity corresponding to the relationship query without the relationship type ru based on the trained conditional adversarial generation network. The relationship category of traditional relationship prediction is expanded from a visible relationship to an unseen relationship category, so that the range of predicting the relationship category is enlarged. And the scale of the training data is reduced from the traditional big data scaleto the learning and prediction of the unseen relationship by only needing a small number of samples or even one sample.
