  • an ontology designer makes these decisions based on the structural properties of a class.
  • an ontology is a formal explicit description of concepts in a domain of discourse (classes (sometimes called concepts)), properties of each concept describing various features and attributes of the concept (slots (sometimes called roles or properties)), and restrictions on slots (facets (sometimes called role restrictions)). An ontology together with a set of individual instances of classes constitutes a knowledge base. In reality, there is a fine line where the ontology ends and the knowledge base begins.
  • Classes describe concepts in the domain
  • ...16 more annotations...
  • A class can have subclasses that represent concepts that are more specific than the superclass.
  • Here we discuss general issues to consider and offer one possible process for developing an ontology. We describe an iterative approach to ontology development: we start with a rough first pass at the ontology. We then revise and refine the evolving ontology and fill in the details. Along the way, we discuss the modeling decisions that a designer needs to make, as well as the pros, cons, and implications of different solutions.
  • In practical terms, developing an ontology includes: �         defining classes in the ontology, �         arranging the classes in a taxonomic (subclass–superclass) hierarchy, �         defining slots and describing allowed values for these slots, �         filling in the values for slots for instances.
  • We can then create a knowledge base by defining individual instances of these classes filling in specific slot value information and additional slot restrictions.
  • Slots describe properties of classes and instances:
  • some fundamental rules in ontology design
  • There is no one correct way to model a domain— there are always viable alternatives. The best solution almost always depends on the application that you have in mind and the extensions that you anticipate. 2)      Ontology development is necessarily an iterative process. 3)      Concepts in the ontology should be close to objects (physical or logical) and relationships in your domain of interest. These are most likely to be nouns (objects) or verbs (relationships) in sentences that describe your domain.
  • how detailed or general the ontology is going to be
  • what we are going to use the ontology for
  • concepts in the ontology must reflect this reality
  • We suggest starting the development of an ontology by defining its domain and scope. That is, answer several basic questions: �         What is the domain that the ontology will cover? �         For what  we are going to use the ontology? �         For what types of questions the information in the ontology should provide answers? �         Who will use and maintain the ontology?
  • plan to use
  • domain
  • If the people who will maintain the ontology describe the domain in a language that is different from the language of the ontology users, we may need to provide the mapping between the languages.
  • One of the ways to determine the scope of the ontology is to sketch a list of questions that a knowledge base based on the ontology should be able to answer, competency questions
  • These competency questions are just a sketch and do not need to be exhaustive.

  • “teaming”: bringing together a team of professionals for a specific task
  • The old cubicle-based, static company is increasingly being replaced by a more fluid and mobile model: “the constant assembly, disassembly, and reassembly of people, talent, and ideas around a range of challenges and opportunities.”
  • Therefore, the new economy and its “seminomadic workforce” will require “new places to gather, work, live, and interact.”
  • ...17 more annotations...
  • The consumer electronics company Plantronics, for example, knowing that on any given day 40% of its workforce will be working elsewhere, designed its corporate campus to only 60% capacity
  • Their joint enterprise, NextSpace, became their first venture into what they call “coworking,” or the creation of “shared collaborative workspaces.”
  • also nurtures what the authors call “managed serendipity” — ad hoc collaboration between people with diverging but complementary skills
  • the number of coworking spaces worldwide has shot up from 30 in 2006 to 1,130 in 2011
  • someone needs to keep an eye on the big picture, to “connect the dots.”
  • workspaces are designed on a flexible, on-demand and as-needed basis
  • Coonerty and Neuner found that the most productive collaborations tended to pair highly specialized experts with big-picture thinkers
  • they were struck by the number of entrepreneurs and freelancers working at coffee shops in the area
  • Business Talent Group
  • Clients get the specialized help they need at a cost below that of a full-time employee or traditional consulting firm, and specialists are well compensated and rewarded with flexible schedules and a greater degree of choice about which projects to take.
  • This has produced a new market dynamic in which the headhunter of yesteryear has been replaced by “talent brokers” who connect highly specialized talent with companies on a project-by-project basis
  • Matthew Mullenweg, doesn’t have much faith in traditional office buildings or corporate campuses: “I would argue that most offices are full of people not working.”
  • On the other hand, Mullenweg is a big believer in face-to-face collaboration and brainstorming, and flies his teams all over the globe to do so.
  • He also set up an informal workspace in San Francisco called the Lounge
  • Additionally, a 2010 Kauffman-Rand study worried that employer-based health insurance, by discouraging risk-taking, will be an ongoing drag on entrepreneurship
  • the problem of payroll taxes for freelancers
  • up to 44% of independent workers encounter difficulty getting paid fully for their work

    Better sensors and sensor systems will improve the products for which Ohio is well known - automotive, aerospace, biomedical, agriculture and food processing - and emerging markets such as advanced energy and advanced materials. And, northeast Ohio has significant business presence and world-class research and development capabilities in Instruments, Controls and Electronics. This provides critical enabling capabilities for development and commercialization of sensor and sensor systems technologies.

action theoretical theory paper

shared by Tiberius Brastaviceanu on 21 Sep 11 - Cached
  • intentionally
  • questions about the nature, variety, and identity of action
  • Should we think of the consequences, conventional or causal, of physical behavior as constituents of an action distinct from but ‘generated by’ the movement? Or should we think that there is a single action describable in a host of ways?
  • ...22 more annotations...
  • Donald Davidson
  • an action
  • is something an agent does that was ‘intentional under some description,’
  • there have been many attempts to map the relations between intentions for the future, acting intentionally, and acting with a certain intention.
  • There has been a notable or notorious debate about whether the agent's reasons in acting are causes of the action
  • rendered the action intelligible in his eyes
  • things that merely happen
  • things they genuinely do
  • distinction between
  • the doings, are the acts or actions of the agent
  • what distinguishes an action from a mere happening or occurrence?
  • An agent performs activity that is directed at a goal
  • adopted on the basis of an overall practical assessment of his options and opportunities
  • awareness
  • that he is performing the activity
  • and that the activity is aimed by him at such-and-such a chosen end
  • It is frequently noted that the agent has some sort of immediate awareness of his physical activity and of the goals that the activity is aimed at realizing.
  • ‘knowledge without observation.’
  • It is also important to the concept of ‘goal directed action’ that agents normally implement a kind of direct control or guidance over their own behavior.
  • For many years, the most intensely debated topic in the philosophy of action concerned the explanation of intentional actions in terms of the agent's reasons for acting
  • Davidson and other action theorists defended the position that reason explanations are causal explanations
  • In the foregoing, reference has been made to explanations of actions in terms of reasons, but recent work on agency has questioned whether contemporary frameworks for the philosophy of action have really articulated the way in which an agent's desires and other pro-attitudes have the distinctive force of reasons in the setting of these ordinary explanations
