Collaborative Information Seeking
Collaborative information seeking (CIS) is a field of research that involves studying situations, motivations, and methods for people working in collaborative groups for information seeking projects, as well as building systems for supporting such activities. Such projects often involve information searching or information retrieval (IR), information gathering, and information sharing. Beyond that, CIS can extend to collaborative information synthesis and collaborative sense-making. Background Seeking for information is often considered a solo activity, but there are many situations that call for people working together for information seeking. Such situations are typically complex in nature, and involve working through several sessions exploring, evaluating, and gathering relevant information. Take for example, a couple going on a trip. They have the same goal, and in order to accomplish their goal, they need to seek out several kinds of information, including flights, hotels, a ...

Information Retrieval
Information retrieval (IR) in computing and information science is the process of obtaining information system resources that are relevant to an information need from a collection of those resources. Searches can be based on 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; stores and manages those documents. Web search engines are the most visible IR applications. Overview An information retrieval process begins when a user or searcher enters a query into the system. Queries are formal statements of information needs, for example search strings in web search engines. In inf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collaborative Learning
Collaborative learning is a situation in which two or more people learn or attempt to learn something together.Dillenbourg, P. (1999). Collaborative Learning: Cognitive and Computational Approaches. Advances in Learning and Instruction Series. New York, NY: Elsevier Science, Inc. Unlike individual learning, people engaged in collaborative learning capitalize on one another's resources and skills (asking one another for information, evaluating one another's ideas, monitoring one another's work, etc.).Chiu, M. M. (2008Flowing toward correct contributions during groups' mathematics problem solving: A statistical discourse analysis. ''Journal of the Learning Sciences'', 17 (3), 415 - 463. More specifically, collaborative learning is based on the model that knowledge can be created within a population where members actively interact by sharing experiences and take on asymmetric roles. Put differently, collaborative learning refers to methodologies and environments in which learners eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human–computer Interaction
Human–computer interaction (HCI) is research in the design and the use of computer technology, which focuses on the interfaces between people (users) and computers. HCI researchers observe the ways humans interact with computers and design technologies that allow humans to interact with computers in novel ways. A device that allows interaction between human being and a computer is known as a "Human-computer Interface (HCI)". As a field of research, human–computer interaction is situated at the intersection of computer science, behavioral sciences, design, media studies, and several other fields of study. The term was popularized by Stuart K. Card, Allen Newell, and Thomas P. Moran in their 1983 book, ''The Psychology of Human–Computer Interaction.'' The first known use was in 1975 by Carlisle. The term is intended to convey that, unlike other tools with specific and limited uses, computers have many uses which often involve an open-ended dialogue between the user and t ...

Multimodal Interaction
Multimodal interaction provides the user with multiple modes of interacting with a system. A multimodal interface provides several distinct tools for input and output of data. Introduction Multimodal human-computer interaction refers to the "interaction with the virtual and physical environment through natural modes of communication", This implies that multimodal interaction enables a more free and natural communication, interfacing users with automated systems in both input and output. Specifically, multimodal systems can offer a flexible, efficient and usable environment allowing users to interact through input modalities, such as speech, handwriting, hand gesture and gaze, and to receive information by the system through output modalities, such as speech synthesis, smart graphics and other modalities, opportunely combined. Then a multimodal system has to recognize the inputs from the different modalities combining them according to temporal and contextual constraintsCasche ...

Integrated Collaboration Environment
An integrated collaboration environment (ICE) is an environment in which a virtual team does its work. Such environments allow companies to realize a number of competitive advantages by using their existing computers and network infrastructure for group and personal collaboration. These fully featured environments combine the best features of web-based conferencing and collaboration, desktop videoconferencing, and instant message into a single easy-to-use, intuitive environment. Recent developments have allowed companies include streaming in real-time and archived modes into their ICE. Common applications found within ICE are: #''Collaborative software'' designed to improve the performance of teams by supporting the sharing and flow of information. It allows for real-time collaboration and conferencing. #''Workflow systems'' facilitate the automation and management of business processes. #''Documentation management systems'' manage a document through all the stages of its process ...

Information Seeking
Information seeking is the process or activity of attempting to obtain information in both human and technological contexts. Information seeking is related to, but different from, information retrieval (IR). Compared to information retrieval Traditionally, IR tools have been designed for IR professionals to enable them to effectively and efficiently retrieve information from a source. It is assumed that the information exists in the source and that a well-formed query will retrieve it (and nothing else). It has been argued that laypersons' information seeking on the internet is very different from information retrieval as performed within the IR discourse. Yet, internet search engines are built on IR principles. Since the late 1990s a body of research on how casual users interact with internet search engines has been forming, but the topic is far from fully understood. IR can be said to be technology-oriented, focusing on algorithms and issues such as precision and recall. Info ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human–computer Information Retrieval
Human–computer information retrieval (HCIR) is the study and engineering of information retrieval techniques that bring human intelligence into the search process. It combines the fields of human-computer interaction (HCI) and information retrieval (IR) and creates systems that improve search by taking into account the human context, or through a multi-step search process that provides the opportunity for human feedback. History This term ''human–computer information retrieval'' was coined by Gary Marchionini in a series of lectures delivered between 2004 and 2006. Marchionini's main thesis is that "HCIR aims to empower people to explore large-scale information bases but demands that people also take responsibility for this control by expending cognitive and physical energy." In 1996 and 1998, a pair of workshops at the University of Glasgow on information retrieval and human–computer interaction sought to address the overlap between these two fields. Marchionini notes the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer-supported Collaborative Learning
Computer-supported collaborative learning (CSCL) is a pedagogical approach wherein learning takes place via social interaction using a computer or through the Internet. This kind of learning is characterized by the sharing and construction of knowledge among participants using technology as their primary means of communication or as a common resource.Stahl, G., Koschmann, T., & Suthers, D. (2006). Computer-supported collaborative learning: An historical perspective. In R. K. Sawyer (Ed.)Cambridge handbook of the learning sciences(pp. 409-426). Cambridge, UK: Cambridge University Press. CSCL can be implemented in online and classroom learning environments and can take place synchronously or asynchronously. The study of computer-supported collaborative learning draws on a number of academic disciplines, including instructional technology, educational psychology, sociology, cognitive psychology, and social psychology. It is related to collaborative learning and computer supported c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer-supported Collaboration
Computer-supported collaboration research focuses on technology that affects groups, organizations, communities and societies, e.g., voice mail and text chat. It grew from cooperative work study of supporting people's work activities and working relationships. As net technology increasingly supported a wide range of recreational and social activities, consumer markets expanded the user base, enabling more and more people to connect online to create what researchers have called a computer supported cooperative work, which includes "all contexts in which technology is used to mediate human activities such as communication, coordination, cooperation, competition, entertainment, games, art, and music" (from CSCW 2004). Scope of the field Focused on output The subfield computer-mediated communication deals specifically with how humans use "computers" (or digital media) to form, support and maintain relationships with others (social uses), regulate information flow (instructional uses), ...

Collaborative Working System
A collaborative working environment (CWE) supports people, such as e-professionals, in their individual and cooperative work. Research in CWE involves focusing on organizational, technical, and social issues. Background Working practices in a collaborative working environment evolved from the traditional or geographical co-location paradigm. In a CWE, professionals work together regardless of their geographical location. In this context, e-professionals use a collaborative working environment to provide and share information and exchange views in order to reach a common understanding. Such practices enable an effective and efficient collaboration among different proficiencies. Description The following applications or services are considered elements of a CWE: * E-mail * Instant messaging * Application sharing * Video conferencing * Collaborative workspace, document management and version control system * Task and workflow management * Wiki group or community effort to edit wiki pa ...
