A media query consists of a media type and one or more expressions, involving media features, which resolve to either true or false.The result of the query is true if the media type specified in the media query matches the type of device the document is being displayed on and all expressions in the media query are true.
Fuzzy retrieval. Fuzzy retrieval techniques are based on the Extended Boolean model and the Fuzzy set theory. There are two classical fuzzy retrieval models: Mixed Min and Max (MMM) and the Paice model. Both models do not provide a way of evaluating query weights, however this is considered by the P-norms algorithm.
Evaluation measures (information retrieval) Evaluation measures for an information retrieval (IR) system assess how well an index, search engine, or database returns results from a collection of resources that satisfy a user's query. They are therefore fundamental to the success of information systems and digital platforms.
Also known as min-max scaling or min-max normalization, rescaling is the simplest method and consists in rescaling the range of features to scale the range in [0, 1] or [−1, 1]. Selecting the target range depends on the nature of the data. The general formula for a min-max of [0, 1] is given as: [3]
A Block Range Index or BRIN is a database indexing technique. They are intended to improve performance with extremely large [i] tables. BRIN indexes provide similar benefits to horizontal partitioning or sharding but without needing to explicitly declare partitions. [1]
Given an array , we wish to answer queries of the form , where . The mode of any array is an element such that the frequency of is greater than or equal to the frequency of . For example, if , then because it occurs three times, while all other values occur fewer times. In this problem, the queries ask for the mode of subarrays of the form .
Range query (computer science) In computer science, the range query problem consists of efficiently answering several queries regarding a given interval of elements within an array. For example, a common task, known as range minimum query, is finding the smallest value inside a given range within a list of numbers.
The terms data dictionary and data repository indicate a more general software utility than a catalogue. A catalogue is closely coupled with the DBMS software. It provides the information stored in it to the user and the DBA, but it is mainly accessed by the various software modules of the DBMS itself, such as DDL and DML compilers, the query optimiser, the transaction processor, report ...
