Abstract: Data may be modeled as an undirected graph. A set of entities and a set of attributes may be defined. A set of relationships may be defined to represent semantic associations with each association connecting at least two entities. Attributes may be associated with entities rather than with relationships. A hierarchical query language with a set of atomic operations on modeled data may be employed. The modeled data may be displayed on a display unit.

Abstract: A method for use with an aggregation operation (e.g., on a relational database table) includes a sorting pass and a merging pass. The sorting pass includes: (a) reading blocks of the table from a storage medium into a memory using an aggregation method until the memory is substantially full or until all the data have been read into the memory; (b) determining a number k of blocks to write back to the storage medium from the memory; (c) selecting k blocks from memory, sorting the k blocks, and then writing the k blocks back to the storage medium as a new sublist; and (d) repeating steps (a), (b), and (c) for any unprocessed tuples in the database table. The merging pass includes: merging all the sublists to form an aggregation result using a merge-sort algorithm.

Abstract: Methods are disclosed of processing a set-level query across one or more attributes, the query being grouped by one or more attributes, whereby groups that satisfy the set-level query may be aggregated over one or more attributes. The methods use bitwise arithmetic to efficiently traverse bitmap and bit-slice vectors and indexes of a data relation to determine groups that solve the set-level query.

Abstract: An ultra wideband dual-frequency combiner includes a combination port (Port 1), a first port (Port 2), a second port (Port 3), two coaxial resonator band pass filters and two direct current channels. The first direct current channel is connected between the first port (Port 2) and the combination port (Port 1). The second direct current channel is connected between the second port (Port 3) and the combination port (Port 1). One end of the first coaxial resonator hand pass filters (610, 611) is electrically connected with the first port (Port 2) via a first blocking capacitor. One end of the second coaxial resonator hand pass filter (620, 621) is electrically connected with the second port (Port 3) via a second blocking capacitor. The other ends of the first coaxial resonator band pass filter and the second coaxial resonator band pass filter are connected with the combination port (Port 1) via a third blocking capacitor. The blocking capacitors are parameter distributed capacitors.

Abstract: One embodiment is a computer-implemented method for classifying documents in a collection of documents according to their intended readerships. The method comprises using a computer to select a document in the collection of documents; and using a computer to determine a characteristic of the selected document, the characteristic being: misleading when the document includes one or more features that are determined to be for a purpose other than reading the document; commercial when the document includes features that are presented for a commercial purpose; or personal when the document includes features of a personal opinion. The method further includes using a computer to classify the selected document as misleading, commercial, or personal according to its determined characteristic; and using a computer to repeat the steps of select document, determine a characteristic of the selected document, and classify the selected document for additional documents in the collection. At least some documents are classified as misleading, at least some documents are classified as commercial, and at least some documents are classified as personal. Other methods and computer program products are also disclosed according to even more embodiments.

Abstract: A method and system for efficiently answering a local neighborhood aggregation query over graph data. A graph which has a plurality of nodes is received and stored in memory. A local neighborhood aggregation query is received. A processing engine applies forward processing with differential index-based pruning, backward processing using partial distribution, or an enhanced backward processing that combines the backward processing and the forward processing. As a result of the forward, backward, or enhanced backward processing, nodes in the graph that have the top-k highest aggregate values over neighbors within h-hops of the nodes are determined. Identities of entities or persons associated with the determined nodes are presented and/or stored.

An external approach may be utilized, creating queries using structured query language on a computer. An algorithm may be used to rewrite the queries. The resulting predicates may be joined to dimension tables corresponding to fact tables. An internal approach may be utilized, using aggregation functions with early aggregation for creating the queries. The results of the slice and dice operations may be outputted to a user on a computer monitor.
