Multisearch
Multisearch is a multitasking search engine which includes both search engine and metasearch engine characteristics with additional capability of retrieval of search result sets that were previously classified by users. It enables the user to gather results from its own search index as well as from one or more search engines, metasearch engines, databases or any such kind of information retrieval (IR) programs. Multisearch is an emerging feature of automated search and information retrieval systems which combines the capabilities of computer search programs with results classification made by a human. Multisearch is a way to take advantage of the power of multiple search engines with a flexibility not seen in traditional metasearch engines. To the end user, a multisearch may appear to be just a customizable search engine; however, its behind-the-scenes technology enables it to put a face to the search process and to retrieve and display also a results set which has been classif ...

Metasearch Engine
A metasearch engine (or search aggregator) is an online information retrieval tool that uses the data of a web search engine to produce its own results. Metasearch engines take input from a user and immediately query search engines for results. Sufficient data is gathered, ranked, and presented to the users. Problems such as spamming reduce the accuracy and precision of results. The process of fusion aims to improve the engineering of a metasearch engine. Examples of metasearch engines include Skyscanner and Kayak.com, which aggregate search results of online travel agencies and provider websites. SearXNG is a generic free and open-source search software which aggregates results from internet search engines and other sources like Wikipedia and is offered for free by more than 70 SearXNG providers. History The first person to incorporate the idea of meta searching was University of Washington student Eric Selberg, who published a paper about his MetaCrawler experiment ...

Computer Multitasking
In computing, multitasking is the concurrent computing, concurrent execution of multiple tasks (also known as Process (computing), processes) over a certain period of time. New tasks can interrupt already started ones before they finish, instead of waiting for them to end. As a result, a computer executes segments of multiple tasks in an interleaved manner, while the tasks share common processing resources such as central processing units (CPUs) and main memory. Multitasking automatically interrupts the running program, saving its state (partial results, memory contents and computer register contents) and loading the saved state of another program and transferring control to it. This "context switch" may be initiated at fixed time intervals (pre-emptive multitasking), or the running program may be coded to signal to the supervisory software when it can be interrupted (cooperative multitasking). Multitasking does not require Parallel computing, parallel execution of multiple task ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Search Engine
A search engine is a software system that provides hyperlinks to web pages, and other relevant information on World Wide Web, the Web in response to a user's web query, query. The user enters a query in a web browser or a mobile app, and the search engine results page, search results are typically presented as a list of hyperlinks accompanied by textual summaries and images. Users also have the option of limiting a search to specific types of results, such as images, videos, or news. For a search provider, its software engine, engine is part of a distributed computing system that can encompass many data centers throughout the world. The speed and accuracy of an engine's response to a query are based on a complex system of Search engine indexing, indexing that is continuously updated by automated web crawlers. This can include data mining the Computer file, files and databases stored on web servers, although some content is deep web, not accessible to crawlers. There have been ma ...

Index (search Engine)
Search engine indexing is the collecting, parsing, and storing of data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, and computer science. An alternate name for the process, in the context of search engines designed to find web pages on the Internet, is '' web indexing''. Popular search engines focus on the full-text indexing of online, natural language documents. Media types such as pictures, video, audio, and graphics are also searchable. Meta search engines reuse the indices of other services and do not store a local index whereas cache-based search engines permanently store the index along with the corpus. Unlike full-text indices, partial-text services restrict the depth indexed to reduce index size. Larger services typically perform indexing at a predetermined time interval due to the required time and processing costs, while agent-based search ...

Database
In computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an application associated with the database. Before digital storage and retrieval of data have become widespread, index cards were used for data storage in a wide range of applications and environments: in the home to record and store recipes, shopping lists, contact information and other organizational data; in business to record presentation notes, project research and notes, and contact information; in schools as flash c ...

Information Retrieval
Information retrieval (IR) in computing and information science is the task of identifying and retrieving information system resources that are relevant to an Information needs, information need. The information need can be specified in the form of a search query. In the case of document retrieval, queries can be based on full-text search, full-text or other content-based indexing. Information retrieval is the science of searching for information in a document, searching for documents themselves, and also searching for the metadata that describes data, and for databases of texts, images or sounds. Automated information retrieval systems are used to reduce what has been called information overload. An IR system is a software system that provides access to books, journals and other documents; it also stores and manages those documents. Web search engines are the most visible IR applications. Overview An information retrieval process begins when a user enters a query into the sys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Search Aggregator
A search aggregator is a type of metasearch engine which gathers results from multiple search engines simultaneously, typically through RSS search results. It combines user specified search feeds (parameterized RSS feeds which return search results) to give the user the same level of control over content as a general aggregator. Soon after the introduction of RSS, sites began publicising their search results in parameterized RSS feeds. Search aggregators are an increasingly popular way to take advantage of the power of multiple search engines with a flexibility not seen in traditional metasearch engines. To the end user, a search aggregator may appear to be just a customizable search engine and the use of RSS may be completely hidden. However, the presence of RSS is directly responsible for the existence of search aggregators and a critical component in the behind-the-scenes technology. History The concept of search aggregation is a relatively recent phenomenon with the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metabrowsing
Metabrowsing refers to approaches to browsing Web-based information that emerged in the late 1990s as alternatives to the standard Web browser. According to LexisNexis the term "metabrowsing" began appearing in mainstream media in March 2000. Since then, the meaning of "metabrowsing" has split into a popular and a more scientific use of the term. Popular use Akin to metasearch, the popular use of the term "metabrowsing" describes an alternative way to viewing Web-based information other than a single Web-page at a time. "Simply put, metabrowsing is a tool or service that enables the user to view more than a single Web page at a time inside a single display unit." According to Dr. Linda Gordon, Liberal Arts Professor at Nova Southeastern University, "metabrowsing is transforming our understanding of the web, therefore, the vocabulary of this new perspective must demonstrate the nature of the metamorphosis. The etymological root 'meta', from the Greek, means 'change' and 'transcende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
