Consequently, any mapping from real world applications into computer applications requires a certain amount of technical background knowledge by the user, where the semantic gap manifests itself. It is a fundamental task of software engineering to close the gap between application specific knowledge and technically doable formalization. For ...
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors.

In binary classification, fall-out is the opposite of specificity and is equal to (). It can be looked at as the probability that a non-relevant document is retrieved by the query. It is trivial to achieve fall-out of 0% by returning zero documents in response to any query.
Query, a precise request for information retrieval made to a database, data structure or information system Query language, a computer language used to make queries into databases and information systems; Query string, in the World Wide Web, is an optional part of a URL; Web search query, a query entered by users into web search engines
Other search engines remove some of the most common words—including lexical words, such as "want"—from a query in order to improve performance. [7] In recent years the SEO best practices around stop words have evolved along with the fields of machine learning and natural language processing. In February 2021, John Mueller, Webmaster Trends ...
In computer science, an inverted index (also referred to as a postings list, postings file, or inverted file) is a database index storing a mapping from content, such as words or numbers, to its locations in a table, or in a document or a set of documents (named in contrast to a forward index, which maps from documents to content). [1]
A query language, also known as data query language or database query language (DQL), is a computer language used to make queries in databases and information systems. In database systems, query languages rely on strict theory to retrieve information. [1] A well known example is the Structured Query Language (SQL).
In SQL, the data manipulation language comprises the SQL-data change statements, [3] which modify stored data but not the schema or database objects. Manipulation of persistent database objects, e.g., tables or stored procedures, via the SQL schema statements, [3] rather than the data stored within them, is considered to be part of a separate data definition language (DDL).
