Award
An award, sometimes called a distinction, is something given to a recipient as a token of recognition of excellence in a certain field. When the token is a medal, ribbon or other item designed for wearing, it is known as a decoration. An award may be described by three aspects: 1) who is given 2) what 3) by whom, all varying according to purpose. The recipient is often to a single person, such as a student or athlete, or a representative of a group of people, be it an organisation, a sports team or a whole country. The award item may be a decoration, that is an insignia suitable for wearing, such as a medal, badge, or rosette (award). It can also be a token object such as certificate, diploma, championship belt, trophy, or plaque. The award may also be or be accompanied by a title of honor, as well as an object of direct value such as prize money or a scholarship. Furthermore, an honorable mention is an award given, typically in education, that does not confer the recipie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Named Entity Recognition
Named-entity recognition (NER) (also known as (named) entity identification, entity chunking, and entity extraction) is a subtask of information extraction that seeks to locate and classify named entities mentioned in unstructured text into pre-defined categories such as person names, organizations, locations, medical codes, time expressions, quantities, monetary values, percentages, etc. Most research on NER/NEE systems has been structured as taking an unannotated block of text, such as this one: And producing an annotated block of text that highlights the names of entities: In this example, a person name consisting of one token, a two-token company name and a temporal expression have been detected and classified. State-of-the-art NER systems for English produce near-human performance. For example, the best system entering MUC-7 scored 93.39% of F-measure while human annotators scored 97.60% and 96.95%.

Molecular Recognition
The term molecular recognition refers to the specific interaction between two or more molecules through noncovalent bonding such as hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, π-π interactions, halogen bonding, or resonant interaction effects. In addition to these ''direct'' interactions, solvents can play a dominant ''indirect'' role in driving molecular recognition in solution. The host and guest involved in molecular recognition exhibit molecular complementarity. Exceptions are molecular containers, including e.g. nanotubes, in which portals essentially control selectivity. Biological systems Molecular recognition plays an important role in biological systems and is observed in between receptor-ligand, antigen-antibody, DNA-protein, sugar- lectin, RNA-ribosome, etc. An important example of molecular recognition is the antibiotic vancomycin that selectively binds with the peptides with terminal D-alanyl-D-alanine in bacterial cells ...

Intra-species Recognition
Intra-species recognition is the recognition by a member of a species of a conspecific (another member of the same species). In many species, such recognition is necessary for procreation. Different species may employ different methods, but all of them are based on one or more senses (after all, this is how the organism gathers information about the environment). The recognition may happen by chemical signature ( smell), by having a distinctive shape or color (sight), by emitting certain sounds (hearing), or even by behaviour patterns. Often a combination of these is used. Among human beings, the sense of sight is usually in charge of recognizing other members of the same species, with maybe the subconscious help of smell. In particular, the human brain has a disproportionate amount of processing power dedicated to finely analyze the features of a human face. This is why we are able to distinguish almost all human beings from each other (barring look-alikes), and a human being f ...

Antigen Recognition
Antigen presentation is a vital immune process that is essential for T cell immune response triggering. Because T cells recognize only fragmented antigens displayed on cell surfaces, antigen processing must occur before the antigen fragment, now bound to the major histocompatibility complex (MHC), is transported to the surface of the cell, a process known as presentation, where it can be recognized by a T-cell receptor. If there has been an infection with viruses or bacteria, the cell will present an endogenous or exogenous peptide fragment derived from the antigen by MHC molecules. There are two types of MHC molecules which differ in the behaviour of the antigens: MHC class I molecules (MHC-I) bind peptides from the cell cytosol, while peptides generated in the endocytic vesicles after internalisation are bound to MHC class II (MHC-II). Cellular membranes separate these two cellular environments - intracellular and extracellular. Each T cell can only recognize tens to hundreds ...

Recognition (sociology)
Recognition in sociology is the public acknowledgment of a person's Social status, status or :wikt:merit, merits (achievements, virtues, service, etc.). In psychology, excessively seeking for recognition is regarded as one of the defining traits of a narcissistic personality disorder. Another example of recognition is when some person is accorded some special status, such as title or classification. According to Charles Taylor (philosopher), Charles Taylor, recognition of one's identity is both a fundamental need and a right, and non- or misrecognition is a form of oppression. In the workplace, recognition has been suggested to increase employee engagement, continuous improvement behaviour, trust in the organization, intention to stay, and satisfaction with management. Others, like Alfie Kohn in ''Punished by Rewards'', point out the dangers of using praise to show recognition, since it may induce compliance in the short-term, but negatively impact quality in the workplace lon ...

Pattern Recognition (psychology)
In psychology and cognitive neuroscience, pattern recognition describes a cognitive process that matches information from a stimulus with information retrieved from memory.Eysenck, Michael W.; Keane, Mark T. (2003). Cognitive Psychology: A Student's Handbook (4th ed.). Hove; Philadelphia; New York: Taylor & Francis. . OCLC 894210185. Retrieved 27 November 2014. Pattern recognition occurs when information from the environment is received and entered into short-term memory, causing automatic activation of a specific content of long-term memory. An early example of this is learning the alphabet in order. When a carer repeats ‘A, B, C’ multiple times to a child, utilizing the pattern recognition, the child says ‘C’ after they hear ‘A, B’ in order. Recognizing patterns allows us to predict and expect what is coming. The process of pattern recognition involves matching the information received with the information already stored in the brain. Making the connection between m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emotion Recognition
Emotion recognition is the process of identifying human emotion. People vary widely in their accuracy at recognizing the emotions of others. Use of technology to help people with emotion recognition is a relatively nascent research area. Generally, the technology works best if it uses multiple modalities in context. To date, the most work has been conducted on automating the recognition of facial expressions from video, spoken expressions from audio, written expressions from text, and physiology as measured by wearables. Human Humans show a great deal of variability in their abilities to recognize emotion. A key point to keep in mind when learning about automated emotion recognition is that there are several sources of "ground truth," or truth about what the real emotion is. Suppose we are trying to recognize the emotions of Alex. One source is "what would most people say that Alex is feeling?" In this case, the 'truth' may not correspond to what Alex feels, but may corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recall (memory)
Recall in memory refers to the mental process of retrieval of information from the past. Along with encoding and storage, it is one of the three core processes of memory. There are three main types of recall: free recall, cued recall and serial recall. Psychologists test these forms of recall as a way to study the memory processes of humansrecall. (2010). In Encyclopædia Britannica. Retrieved March 04, 2010, from Encyclopædia Britannica Online: http://www.britannica.com/EBchecked/topic/493353/recal/ref> and animals. Two main theories of the process of recall are the two-stage theory and the theory of Encoding specificity principle, encoding specificity. Theories Two-stage theory The ''two-stage theory'' states that the process of recall begins with a search and retrieval process, and then a decision or recognition process where the correct information is chosen from what has been retrieved. In this theory, recognition only involves the latter of these two stages, or processes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pareidolia
Pareidolia (; ) is the tendency for perception to impose a meaningful interpretation on a nebulous stimulus, usually visual, so that one sees an object, pattern, or meaning where there is none. Common examples are perceived images of animals, faces, or objects in cloud formations, seeing faces in inanimate objects, or lunar pareidolia like the Man in the Moon or the Moon rabbit. The concept of pareidolia may extend to include hidden messages in recorded music played in reverse or at higher- or lower-than-normal speeds, and hearing voices (mainly indistinct) or music in random noise, such as that produced by air conditioners or fans. Scientists have taught computers to use visual clues to "see" faces and other images. Etymology The word derives from the Greek words ''pará'' (, "beside, alongside, instead f) and the noun ''eídōlon'' (, "image, form, shape"). The German word was used in articles by Karl Ludwig Kahlbaum—for example in his 1866 paper "" ("On Delusion of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Face Perception
Facial perception is an individual's understanding and interpretation of the face. Here, perception implies the presence of consciousness and hence excludes automated facial recognition systems. Although facial recognition is found in other species, this article focuses on facial perception in humans. The perception of facial features is an important part of social cognition. Information gathered from the face helps people understand each other's identity, what they are thinking and feeling, anticipate their actions, recognize their emotions, build connections, and communicate through body language. Developing facial recognition is a necessary building block for complex societal constructs. Being able to perceive identity, mood, age, sex, and race lets people mold the way we interact with one another, and understand our immediate surroundings. Though facial perception is mainly considered to stem from visual intake, studies have shown that even people born blind can learn face ...

Visual Object Recognition
Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context. Basic stages of object recognition Neuropsychological evidence affirms that there are four specific stages identified in the process of object recognition. These stages are: :Stage 1 Processing of basic object components, such as color, depth, and form. :Stage 2 These basic components are then grouped on the basis of similarity, providing information on distinct edges to the visual form. Subsequently, figure–ground (perception), figure-ground segregation is able to take place. :Stage 3 The visual representation is matched with structural descriptions in memory. :Stage 4 Semantic attributes are applied to the visual representatio ...
