In one scenario where a single node can service a search request in 0. If incoming searches cross the desired service threshold, the system can reserve new memory locations accordingly. Service response time is only one factor of many when selecting the number of new memory locations. Other factors include location, cost, time to duplicate, available machines, competing domain-specific searches, service level agreements SLAs , green computing, energy consumption, energy efficiency, etc.

Other distribution scenarios exist for selecting the number of new memory locations.

A New Approach for Combining the Similarity Values in Ontology Alignment

The system distributes processing more or additional domain-specific searches amongst the at least one new memory location An example algorithm for performing this task is roughly analogous to the translation layer , shown in FIGS. Once the data is in multiple locations, the system applies an algorithm to distribute searches across the multiple locations. The system can randomly distribute processing of searches amongst all memory locations or distribute them serially or based on other criteria. The algorithm can vary based on time of day, quality of service constraints, competing domain-specific searches, cost, and so forth.

While the number of searches remains high, the system will maintain the expanded search space and continue to distribute searches amongst at least part of the expanded search space and the original search space. In time, the demand for searches in a particular domain may be reduced or some other event may affect the need for the expanded search space.

Description:

In order to shrink the number of memory locations or the search space, the system optionally identifies a reduction event related to the domain-specific searches and collapses the expanded search space such that searches for the key data are processed with data in a reduced search space smaller than the expanded search space but having at least one memory location In the sportscar example, if the buzz dies down around the sportscar after the manufacturer reveals that it gets a maximum of 3 miles per gallon, assume that searches for the sportscar sharply taper off.

When searches drop below a certain threshold, the system collapses the expanded search space by deleting the data in all or some of the new memory locations or controlling the algorithm to no longer include those memory locations in the distribution. The system can do this in one step or gradually with a series of steps.

The first memory location can act as a parent of all the new memory locations and can be uncollapsable, but in one aspect, collapsing the expanded search space is not limited to preserving the original memory location so long as at least one location still contains the key data. For example, the system duplicates the original memory location at address 0x to memory locations 0x0A29, 0xC3F0, and 0x82D2, each of which can be in a different computer.

The system can collapse 0x first, even though it is the original memory location. The workload manager can intelligently decide which memory location is best suited for collapsing first. This may be based on time i. The system can collapse the expanded search space by removing any of the memory locations in any order. In one variation, the system further organizes hit rates by network segment, identifies a network segment associated with searches for the key data, and duplicates the key data to at least one new memory location in close proximity to the identified network segment.

For example, if key data relates to the Green Bay Packers and most searches originate in Wisconsin, then the system identifies network connections between the compute environment and Wisconsin as key network segments. The system duplicates key data regarding the Green Bay Packers as close to the key network segment as possible. Or, for example, if the network path with the least latency to Wisconsin is from Des Moines, the system can duplicate the key data to memory locations in Des Moines and provision nodes and other network resources in a similar manner.

A system can predictively expand a search space by receiving information associated with an expected increase in use of a search phrase or searches specific to a particular domain to be processed in a search space in a database , identifying data in the search space having at least one memory location in the database, the data being data identified in response to the domain-specific searches , expanding the search space by duplicating data in the search space into at least one new memory location and distributing more or additional domain-specific searches amongst the expanded search space In other words, searches that are received after the duplication of the data are then distributed amongst at least the ne expanded search space and preferably including the original search space as well.

Information regarding an expected increase in use of a search phrase can be as simple as compiling a list of upcoming summer movies and responding to the expected increase in Internet searches for each upcoming movie. The number of duplicated memory locations can correlate with the each movie's previews and expected box office performance, for example.

What is BI?

In the case of an election where 10 individuals are competing for a nomination for candidacy, the system can predictively expand the search space for each of the 10 individuals in the weeks before the nomination. One example way of identifying domain-specific data is through a special administrative search field. An administrator may have a google search field such that the data that is retrieved is identified as hot data and immediately duplicated as disclosed herein.

This can be done manually as above or automated. Prediction based on new website data may also be used. For example, web crawling algorithms can analyze websites and data obtained therefrom. If new websites have recently been deployed or built that can be identified in a particular domain, then the system can act to prepare extra indexed data as set forth herein to manage predicted searches to those websites.

In another example, the system may analysis blogs to identify topics or terms that are gaining traction and predictively prepare for additional searches on those topics or terms. Often, searches for key data are cyclical.

Cyclical searches can occur on a daily, weekly, monthly, yearly, or other period. For example, searches for Santa Clause spike annually during December, searches for news spike daily in the morning hours on weekdays, and searches for the magicicada spike every 13 or 17 years in different regions. In order to address these cyclical searches, the system can further store received information in a log organized by date and time, predict a schedule of expected increases based on the log, and expand the search space based on the predicted schedule.

As noted above, the data that may be searched is any data. In one aspect, the data is indexed data that is obtained from crawling and indexing websites. In another aspect, the data is the website itself. In that case, the system may identify an event such as response time or hit rates to a certain website and dynamically duplicate the website itself such that the requests for the particular URL are distributed to at least one new memory location. The collapse may occur, for example, by modifying i. This may be helpful if there are too many requests for a streamed video presentation at a website, for example, and additional servers are necessary to manage the requests.

For example, the manager can reserve a set of CPU's, perhaps re-provisioning an appropriate operating system on the nodes say from Microsoft Windows to Linux , copy the data into cache, and initiate triggered jobs to begin streaming video data from the new nodes to additional search requests from users. The compute environment mentioned herein may be any utility computing, cluster, grid, cloud computing environment, on-demand center, server farm, and so forth. The workload manager of the present disclosure can be configured to manage searches for data in any type of computing environment.

Therefore, whether the data is web crawled index data, website data per se, or any other type of database, the principled disclosed herein can improve the search times and service response for inquiries or searches into such databases.
