Collaborative Search Engine
Collaborative search engines (CSE) are web search engines and enterprise searches within company intranets that let users combine their efforts in 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 ... (IR) activities, share information resources collaboratively using knowledge tags, and allow experts to guide less experienced people through their searches. Collaboration partners do so by providing query terms, collective tagging, adding comments or opinions, rating search results, and links clicked of former (successful) IR activities to users having the same or a related information need. Models of collaboration Collaborative search engines can be classified along several dimensions: intent (explicit and implicit) and synchronization, depth of mediation, tas ...

Web 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 ...

Enterprise Search
Enterprise search is software technology for searching data sources internal to a company, typically intranet and database content. The search is generally offered only to users internal to the company. Enterprise search can be contrasted with web search, which applies search technology to documents on the open web, and desktop search, which applies search technology to the content on a single computer. Enterprise search systems index data and documents from a variety of sources such as: file systems, intranets, document management systems, e-mail, and databases. Many enterprise search systems integrate structured and unstructured data in their collections. Enterprise search systems also use access controls to enforce a security policy on their users. Enterprise search can be seen as a type of vertical search of an enterprise. Components of an enterprise search system In an enterprise search system, content goes through various phases from source repository to search results ...

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] |
Knowledge Tags
In information systems, a tag is a keyword or term assigned to a piece of information (such as an Internet bookmark, multimedia, database record, or computer file). This kind of metadata helps describe an item and allows it to be found again by browsing or searching. Tags are generally chosen informally and personally by the item's creator or by its viewer, depending on the system, although they may also be chosen from a controlled vocabulary. Tagging was popularized by websites associated with Web 2.0 and is an important feature of many Web 2.0 services. It is now also part of other database systems, desktop applications, and operating systems. Overview People use tags to aid classification, mark ownership, note boundaries, and indicate online identity. Tags may take the form of words, images, or other identifying marks. An analogous example of tags in the physical world is museum object tagging. People were using textual keywords to classify information and objects lon ...

Information Need
The term information need is often understood as an individual or group's desire to locate and obtain information to satisfy a conscious or unconscious need. Rarely mentioned in general literature about needs, it is a common term in information science. According to Hjørland (1997) it is closely related to the concept of relevance: If something is relevant for a person in relation to a given task, we might say that the person needs the information for that task. Information needs are related to, but distinct from information requirements. They are studied for: # The explanation of observed phenomena of information use or expressed need; # The prediction of instances of information uses; # The control and thereby improvement of the utilization of information manipulation of essential conditions. Background The concept of information needs was coined by an American information journalisRobert S. Taylorin his 1962 articl"The Process of Asking Questions"published in ''American ...

Collaborative Filtering
Collaborative filtering (CF) is, besides content-based filtering, one of two major techniques used by recommender systems.Francesco Ricci and Lior Rokach and Bracha ShapiraIntroduction to Recommender Systems Handbook, Recommender Systems Handbook, Springer, 2011, pp. 1–35 Collaborative filtering has two senses, a narrow one and a more general one. In the newer, narrower sense, collaborative filtering is a method of making automatic predictions (filtering) about a user's interests by utilizing preferences or taste information collected from many users (collaborating). This approach assumes that if persons ''A'' and ''B'' share similar opinions on one issue, they are more likely to agree on other issues compared to a random pairing of ''A'' with another person. For instance, a collaborative filtering system for television programming could predict which shows a user might enjoy based on a limited list of the user's tastes (likes or dislikes). These predictions are specific to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recommender System
A recommender system (RecSys), or a recommendation system (sometimes replacing ''system'' with terms such as ''platform'', ''engine'', or ''algorithm'') and sometimes only called "the algorithm" or "algorithm", is a subclass of information filtering system that provides suggestions for items that are most pertinent to a particular user. Recommender systems are particularly useful when an individual needs to choose an item from a potentially overwhelming number of items that a service may offer. Modern recommendation systems such as those used on large social media sites make extensive use of AI, machine learning and related techniques to learn the behavior and preferences of each user and categorize content to tailor their feed individually. Typically, the suggestions refer to various decision-making processes, such as what product to purchase, what music to listen to, or what online news to read. Recommender systems are used in a variety of areas, with commonly recognised ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jumper 2
''Jumper'' is a 2008 American science fiction action film loosely based on Steven Gould's 1992 novel of the same name. Directed by Doug Liman, the film stars Hayden Christensen as a young man capable of teleporting, as he is pursued by a secret society intent on killing him. Jamie Bell, Rachel Bilson, Max Thieriot, AnnaSophia Robb, Diane Lane, Michael Rooker, and Samuel L. Jackson also star. The script went through a rewrite prior to filming, and the roles for the main characters were changed during production. Filmed in 20 cities and 14 countries from 2007 to 2008 and released on February 14, 2008, the film grossed $225 million worldwide and received generally negative reviews from critics, mostly because of the many changes to Gould's novel, rushed plot, and anticlimactic ending. Plot After falling into the Huron River, 15-year-old David Rice discovers that he can teleport, or "jump". He escapes his abusive father and moves to New York City, where he robs banks b ...

Seeks
Seeks is a free and open-source project licensed under the GNU Affero General Public License version 3 (AGPL-3.0-or-later). It exists to create an alternative to the current market-leading search engines, driven by user concerns rather than corporate interests. The original manifesto was created by Emmanuel Benazera and Sylvio Drouin and published in October 2006. The project was under active development until April 2014, with both stable releases of the engine and revisions of the source code available for public use. In September 2011, Seeks won an innovation award at the Open World Forum Innovation Awards. The Seeks source code has not been updated since April 28, 2014 and no Seeks nodes have been usable since February 6, 2016. User control Seeks aims to give the control of the ranking of results to the users, as search algorithms are often less accurate than humans. It relies on a distributed collaborative filter to let users personalize and share their preferred results ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community Of Practice
A community of practice (CoP) is a group of people who "share a concern or a passion for something they do and learn how to do it better as they interact regularly". The concept was first proposed by cognitive anthropologist Jean Lave and educational theorist Etienne Wenger in their 1991 book ''Situated Learning''. Wenger significantly expanded on this concept in his 1998 book ''Communities of Practice''. A CoP can form around members' shared interests or goals. Through being part of a CoP, the members learn from each other and develop their identities. CoP members can engage with one another in physical settings (for example, in a lunchroom at work, an office, a factory floor), but CoP members are not necessarily co-located. They can form a virtual community of practice (VCoP) where the CoP is primarily located in an online community such as a discussion board, newsgroup, or on a social networking service. Communities of practice have existed for as long as people have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community Of Interest
A community of interest, or interest-based community, is a community of people who share a common interest or passion. These people exchange ideas and thoughts about the given passion, but may know (or care) little about each other outside this area. Participation in a community of interest can be compelling, entertaining and create a community where people return frequently and remain for extended periods. Frequently, they cannot be easily defined by a particular geographical area. In other words, "a community of interest is a gathering of people assembled around a topic of common interest. Its members take part in the community to exchange information, to obtain answers to personal questions or problems, to improve their understanding of a subject, to share common passions or to play." In contrast to a spatial community, "a community of interest is defined not by space, but by some common bond (e.g. feeling of attachment) or entity (e.g. farming, church group)". Online communi ...
