摘要： An online data fusion system receives a query, probes a first source for an answer to the query, returns the answer from the first source, refreshes the answer while probing an additional source, and applies fusion techniques on data associated with an answer that is retrieved from the additional source. For each retrieved answer, the online data fusion system computes the probability that the answer is correct and stops retrieving data for the answer after gaining enough confidence that data retrieved from the unprocessed sources are unlikely to change the answer. The online data fusion system returns correct answers and terminates probing additional sources in an expeditious manner without sacrificing the quality of the answers.

摘要： A method and system for truth discovery may implement a methodology that accounts for accuracy of sources and dependency between sources. The methodology may be based on Bayesian probability calculus for determining which data object values published by sources are likely to be true. The method may be recursive with respect to dependency, accuracy, and actual truth discovery for a plurality of sources.

摘要： A method for securing content in a database includes identifying a challenge column associated with a database column referenced in an update query. A challenge value for the challenge column may be received and resolved for a match with a corresponding value stored in the challenge column. In case of a match, the update query may be certified for execution on the database, otherwise, the update query may be prevented from executing. Challenge columns may be determined by an analysis of the database on the basis of discriminating power, description complexity, and/or diversity.
摘要翻译：用于保护数据库中的内容的方法包括识别与更新查询中引用的数据库列相关联的挑战列。可以接收并解决与挑战列中存储的对应值的匹配的挑战列的挑战值。在匹配的情况下，可以认证更新查询以在数据库上执行，否则可以防止更新查询执行。挑战列可以通过基于区分力，描述复杂度和/或多样性的数据库分析来确定。

摘要： Techniques for extending memory addressing with more accessing range are disclosed. According to one aspect of the techniques, an apparatus for extending addressing space comprises a plurality of extended memories, each being allocated an unique identifier, a direct addressing memory reserving a data cell as a public identifier cell for receiving the identifier of each of the extended memories to be accessed, a decision unit determining that which one of the extended memories is to be accessed by comparing an identifier received by the public identifier cell with the identifier of each of the extended memories, and a mapping unit mapping one of the extended memories determined by the decision unit to be accessed onto the direct addressing memory so that the one of the extended memories can be indirectly accessed by directly accessing the direct addressing memory.

摘要： The subject disclosure pertains to efficient computation of the difference between queries by exploiting commonality between them. A minimal difference query (MDQ) is generated that roughly corresponds to removal of as many joins as possible while still accurately representing the query difference. The minimal difference can be employed to further substantially the scope of view matching where a query is not wholly subsumed by a view. Additionally, the minimal difference query can be employed as an analytical tool in various contexts.
摘要翻译：本发明涉及通过利用它们之间的共性来有效地计算查询之间的差异。生成最小差异查询（MDQ），大致对应于删除尽可能多的连接，同时仍准确地表示查询差异。可以使用最小差异来进一步实质地观察视图匹配的范围，其中查询未被完全包含在视图中。另外，最小差异查询可以用作各种上下文中的分析工具。

摘要： An inventory management system tracks consumables used in creation of secure documents through an identification document issuance process. The system assigns states to card and non-card consumables, and these states are used to track consumables from the vendor's inventory to the issuer's inventory. The system includes functions for managing inventory, shipping and receiving, use management, inventory auditing and secure material destruction. Electronic packing lists are transmitted between vendor and issuer systems to verify shipments. Embedded identification numbers, carried in machine readable codes on consumables, are used to track consumables through the document creation and issuing process.

摘要： The invention provides systems and methods relating to generating a unified determination based on subdetermination, and in particular, generating a unified score based on respective scores. For example, the invention provides a method for generating a unified determination based on subdeterminations, the method including generating a first subdetermination based on first criteria; generating a second subdetermination based on second criteria; and generating a unified determination based on the first subdetermination and the second subdetermination. The generation of the unified determination includes (a) assigning, using iterative processing, an assigned weighting respectively to the first determination and second determination; (b) determining if the assigned weighting satisfies at least one constraint; (c) comparing the assigned weighting to an optimized weighting, which was previously determined, to determine if the assigned weighting is improved over the optimized weighting; and (d) if the assigned weighting is improved, then assigning the assigned weighting to be the optimized weighting.
