摘要： A query of at least one mark-up language document has a path expression comprising a conjunction, a first filter and a second filter. The first filter has a first probe. The second filter has a second probe. The first and second filters form a between filter having start and stop values specified by the first and second probes. A plan to process the query is generated based on, at least in part, a range defined by the start and stop values. An index of mark-up language documents is defined by another path expression; the index comprises values of mark-up language documents that satisfy the other path expression; the values are key values of the index. The plan is to perform a single scan of the key values from the start value to the stop value to identify at least one key value that satisfies the between filter.

摘要： Various embodiments of a computer-implemented method, computer program product, and data processing system are provided that identify a range filter in a mark-up language query. In response to receiving a query of at least one mark-up language document, the query comprising a plurality of singleton filters, at least one group of the plurality of singleton filters are identified. Each group of comprises at least two singleton filters, wherein each group is equivalent to a range filter having a start value and a stop value. The start value and stop value are based on at least two singleton filters of each group. A query plan is generated to process the query based on, at least in part, a range defined by the start value and the stop value of the at least two singleton filters of each group.

摘要： Multiple nonoverlapping languages within a single document can be identified. In one embodiment, for each of a set of candidate languages, a set of non-overlapping languages is defined. The document is analyzed under the hypothesis that the whole document is in one language and that part of the document is in one language while the rest is in a different, non-overlapping language. Language(s) of the document are identified based on comparing these competing hypotheses across a number of language pairs. In another embodiment, transitions between non-overlapping character sets are used to segment a document, and each segment is scored separately for a subset of candidate languages. Language(s) of the document are identified based on the segment scores.

摘要： Methods for executing a query on data that has been partitioned into a plurality of partitions are provided. The method includes providing partitioned data including one or more columns and the plurality of partitions. The partitioned data includes a limit key value associated with each column for a given partition. The method further includes receiving a query including a predicate on one of the one or more columns of the partitioned data; and utilizing the predicate on the one of the one or more columns in a pruni.ng decision on at least one of the one or more partitions based on the limit key values associated with the plurality of partitions.

摘要： An “impostor profile” for a language is used to determine whether documents are in that language or no language. The impostor profile for a given language provides statistical information about the expected results of applying a language model for one or more other (“impostor”) languages to a document that is in fact in the given language. After a most likely language for a test document is identified, the impostor profile is used together with the scores for the test document in the various impostor languages to determine whether to identify the test document as being in the most likely language or in no language.
