Deﬁnition of Language

• A language is a set of standard sensory cues
that represent ideas.
• these cues can be visual, auditory, tactile,
or, less commonly, olfactory or
gastronomic

Tuesday, January 22, 13

Properties of Language
• Vocabulary - a standard set of cues
• Grammar - rules for how those cues go
together to create meaning. (Also known as
syntax rules)
• Logic - the resulting meaning that is derived
from the combination of vocabulary
according to grammar rules.

Tuesday, January 22, 13

Logic = grammar +
vocabulary

Tuesday, January 22, 13

Examples of vocabulary:
• In a design language
• icons are used to represent pieces of
data
• glyphs are used to represent operations
on those pieces of data
• In a mathematical language?
• ______________
• ______________
Tuesday, January 22, 13

Grammar in languages

• In a mathematical language:
• “A+B” means add A and B together
• In a design language?
• ______________________

Tuesday, January 22, 13

Logic in Languages

• All languages convey ideas.
• All ideas are built upon logic.

Tuesday, January 22, 13

Basic logic

• All ideas are made up of statements that
are either true or false.
• ie: I am wearing a red jacket.
• is this true or false?

Tuesday, January 22, 13

Statements
• All statements are made up of subjects and
predicates
• ie: I am wearing a red jacket.
• “I” is the subject
• “am wearing a red jacket” is the
predicate
• The predicate is a property of the
subject

Tuesday, January 22, 13

Statement = subject +
predicate
• Or, the relationship between subject and
predicate is a statement that is either true
or false.

Tuesday, January 22, 13

Subjects and Predicates
• Can be viewed as:
• message and recipient
• action and target
• nouns and verbs
• values and operands
• objects and methods
• Data and functions
Tuesday, January 22, 13

In interface design:

• The purpose of an interface is to facilitate
the manipulation of data.
• In this case, the data is the subject
• the manipulation is the predicate

Tuesday, January 22, 13

Interface as a language
• In an interface, we represent both data and
operations visually.
• Data can be represented as an icon, a 2D
image on a canvas, a 3D model in a
viewport, or even text in a document
• Operations can be represented buttons,
list items, cursors, callouts, tooltips, etc.

Tuesday, January 22, 13

• By understanding the logical implications of
an interface we can do the following:
• choose appropriate imagery to describe
both the data and the operations we are
representing
• visually group interface elements in an
intuitive scheme that makes it easy to
access
• combine and reduce multiple interface
elements into a single, all-encompassing
element. (This is the same as shortening a
sentence in a written language.)

Knowledge structures officialJo Elliott

��

The document discusses knowledge structures and what is known about how humans acquire and organize knowledge. It covers several topics, including how language and knowledge are intrinsically linked, how knowledge is categorized and associated within our minds, and different methods for eliciting and measuring people's knowledge structures, such as interviews, observation, and computerized testing that uses natural language processing techniques.

Theories of first language learningAlan Bessette

��

The document discusses several theories of first language acquisition: - Behaviorism views language learning as habit formation through reinforcement, but cannot explain how children learn despite variable input or produce novel utterances. - Universal Grammar posits an innate language acquisition device that guides rule formation even with variability, but does not fully account for vocabulary or social aspects of language. - Cognitive development theory links language learning to cognitive stages and categorization, explaining vocabulary but less so grammar. - The functional theory emphasizes learning through social interaction, but cannot alone explain consistency across learners or initial rule-forming. Overall, the document concludes that no single theory is sufficient and that aspects of each may contribute to explaining language acquisition.

1) Cognition involves thinking, language, and intelligence and refers to how the brain processes information through understanding, organizing, analyzing, and communicating it. 2) Concepts are mental representations of categories that are held together by common features, prototypes, or exemplars. Expertise and culture can influence what concepts we use. 3) Problem solving involves finding a solution while decision making involves choosing between options, though neither is always straightforward due to heuristics, biases, and limitations in our thinking. 4) Theories of intelligence include the general (g) versus specific (s) distinction as well as models incorporating fluid and crystallized intelligence and multiple intelligences. Intelligence has both genetic and environmental influences.

This document summarizes key points from a presentation on the language of work. It discusses Neil Mercer's ideas about different types of talk - disputational, cumulative, and exploratory. Exploratory talk, where ideas are challenged respectfully and reasons given, is regarded as the best model. The document also gives examples of how English is used for business purposes in specific locations, even if it is not the main home language. In Macau and Bangalore, English serves to facilitate formal work communication but is not used for informal discussion. The presentation examines language as a cultural tool and how analysis can reveal distinctive patterns that emerge within different professions.

Visual-Semantic Embeddings: some thoughts on LanguageRoelof Pieters

��

Language technology is rapidly evolving. A resurgence in the use of distributed semantic representations and word embeddings, combined with the rise of deep neural networks has led to new approaches and new state of the art results in many natural language processing tasks. One such exciting - and most recent - trend can be seen in multimodal approaches fusing techniques and models of natural language processing (NLP) with that of computer vision. The talk is aimed at giving an overview of the NLP part of this trend. It will start with giving a short overview of the challenges in creating deep networks for language, as well as what makes for a “good” language models, and the specific requirements of semantic word spaces for multi-modal embeddings.

The document discusses how users interact with and learn tools. It notes that users develop mental models of tools as they use them, and that they typically only regularly use a select few tools that fit their preferences, ignoring many other available tools due to the effort required to learn new ones. It suggests that good software should provide many options but also cleverly hide unused tools to avoid overwhelming interfaces plagued by "bloat".

Promoting Sustainable Development of Hill Areas --Issues and OptionsJIT KUMAR GUPTA

��

Managing and Rationalising India’s Hill Areas Growth and Development ; Hill areas are known to be different and distinct from plain areas of any country, because of its unique diversity, physiography, structure, topography, morphology, flora, fauna, herbs, fruits, vegetation, bio-diversity, climate, culture, heritage, fragility, vulnerability, nature, natural resource, views, quality of life, lakes, glaciers, mobility, infrastructure, built structures etc. Occupying 17% geographical areas and housing 11% national population, hill areas occupy unique space and importance in the growth story of India, as a nation. Despite distinct character, role , relevance and importance of rational planned development of hill areas, its overall / integrated development and management has been marginalized. With priority and resources going to the plain areas of the country, hill areas are being subjected to large unplanned, irrational and sub-standard growth and development. Accordingly, hill areas are fast becoming hotbeds of vulnerability, both natural and manmade, facing large number of challenges in terms of earthquakes, landslides and flooding, leading to massive loss of human life, animals, infrastructure, built environment and property. Current scenario of irrational, unplanned and haphazard development in hill areas can be, primarily and essentially, attributed to the absence of adequately trained manpower in the art and science of planning, development and management of the hill areas and giving low priority to rationalising development of hill areas. Having special and specific features, hill areas pose different/unique challenges in planning and development and accordingly need different skill-sets, understanding, expertise and approach to its planning and development. Unfortunately, despite having large area and housing large population, no institution in the country offers specialized course in the planning, development , construction and management of hill areas. It is time for Government of India and hill states of India, to ask all IITs/Nits/SPAs and other private universities, located in the hill states to run dedicate specialized courses for the planning, development and management of hill areas. In addition, Government of India, must enact a law and Constitute a High Powered National, Hill Area Planning and Development Authority , on the pattern of NCR Delhi , comprising of representatives of Government of India, hill states and experts from the related fields, under the overall Chairmanship of Minister-in Charge Hill States with Ministers of hill states, Chief Secretaries of Hill States as members , to define the agenda and roadmap for the integrated growth and development of hill states of the country. The Authority should be mandated to prepare the Regional plan of the entire Himalayan Region and provide framework for the states to draw its own Regional Plan. This would help in not only ensuring integrated growth

JAIN ARCHITECTURE AND BUDDHIST - Copy.pptprakriti123

��

Jain and Buddhist architecture have distinct characteristics, yet they share some similarities due to their origins in ancient India. Here's an overview of both: Jain Architecture Jain architecture reflects the religion's emphasis on asceticism, simplicity, and non-violence. Some key features include: 1. Rock-Cut Caves: Early Jain architecture included rock-cut caves, similar to Buddhist caves. Examples: Udayagiri and Khandagiri Caves (Odisha), Ellora Jain Caves (Maharashtra). 2. Temples: Built using marble or sandstone with intricate carvings. Often located on hilltops. Temples follow the Nagara style (North India) or Dravidian style (South India). Examples: Dilwara Temples (Rajasthan), Ranakpur Temple (Rajasthan), Palitana Temples (Gujarat). 3. Manastambha (Pillars of Honor): Tall, free-standing pillars, often found in temple complexes. Symbolize Jain spiritual ideals. 4. Towering Shikharas (Spires): Unlike Hindu temples, Jain spires are often clustered and highly decorative. Buddhist Architecture Buddhist architecture evolved from simple stupas to grand monasteries and temples. 1. Stupas: Dome-shaped structures containing relics of the Buddha. Example: Sanchi Stupa (Madhya Pradesh). 2. Rock-Cut Caves: Monasteries and chaitya halls carved into mountains. Examples: Ajanta and Ellora Caves, Karla and Bhaja Caves (Maharashtra). 3. Viharas (Monasteries): Simple living quarters for monks, later developed into grand structures. Example: Nalanda and Vikramshila Universities. 4. Pagodas (in later periods): Tall, multi-tiered structures found in China, Japan, and Southeast Asia.
