Ambiguity of Natural Language and Computer Language Interpretation

Bad Cop Good Cop Language Abmiguity

In his book “The Stuff of Thought: Language as a Window into Human Nature”, Steven Pinker gave the following defense of language ambiguity: Imagine you are stopped by a traffic cop for a violation. You would rather not get a ticket, and consider offering the cop a bribe. You have options: no bribe and definitely get the ticket; try a bribe and hopefully the cop will accept and let you go free this time. But what if the cop is an honest cop and doesn’t accept bribes? Then you just bought yourself a trip to jail for bribing an officer! That’s the worst possible outcome — a traffic ticket is better than a trip to jail AND a traffic ticket. But what if you just “sort of” offer the officer a bribe? Wave a wad of cash without actually offering it to the officer? A dishonest cop might take you up on the offer and let you go without a ticket. An honest cop could ignore the whole cash waving and write a ticket; or he could ask for clarification: “Are you trying to bribe me?” “On, no, officer. Of course not!” And you are left with a traffic ticket…

Task Analysis and Product Design

Kids from India and Vegetable Choices

Imagine your were given an assignment to develop a product that could help people eat healthy. How would you go about creating such a thing? What would you need to learn/understand? What is the right medium or technology vehicle for such a product? How would you even start? Below is a very brief outline of how to get started and the key tools necessary for the job. Project Goals The first order of business is figuring out the business needs and goals: What is the product really supposed to do? You have to ask this even if you are the one who is the client on this project. But, most probably, you are working for someone else — the client — and you have to start by understanding what your client really wants to do. You can do that in several ways: Analyzing the Request for Proposals: On many such projects, there will be an initial document, something like an RFP, that outlines the business goals and desires of the client. While some RFPs are very detailed and fully fleshed out, most are not. There are many reasons for this. Some clients are worried someone will “steal” their ideas and…

Musings on Failure in School

by  • 

The Math Obstacle In the past few years, reports came out showing strong correlation between failing Algebra and graduation rates — if a kid fails math, he/she won’t be getting their high school diplomas. Here are a few articles describing the studies: “Is Removing Algebra a Key to Reform?” by Daniel Duerden, August 13, 2012 “A Comprehensive Study of the Predictors of High School Outcomes: Why Some Students Graduate on Time While Others Drop Out”. “A Correlation Study of Accuplacer Math and Algebra Scores and Math Remediation on the Retention and Success of Students in the Clinical Laboratory Technology Program at Milwaukee Area Technical College” by James Manto, August 2006. “Is high school tough enough: Full report” by The Center for Public Education. There are many more… Some suggested that based on evidence, we might just want to drop the math curriculum from high school graduation requirement — if there’s a strong correlation, perhaps by removing math, we might remove the problem and more kids graduate. Obviously, I don’t think that this a great solution. But I do come across the math problem a lot as part of the educational evaluations I do in my small practice. What I see…

RE: Tracing the Spark of Creative Problem-Solving

by  • 

Article:  Carey, B. (2010). “Tracing the Spark of Creative Problem-Solving.” nytimes.com. Visited on October 29th, 2012: http://www.nytimes.com/2010/12/07/science/07brain.html Summary:  Puzzles come in a wide variety of formats. They are appealing to people both because of the dopamine rush of arriving at a solution, and also because they shift the brain into an open, playful state. Puzzles are solved in two main ways — either through insight thinking or analytical thinking.  Insight thinking is when an answer comes to a person suddenly, seemingly out of the blue. Analytical thinking involves employing a systematic approach of testing available possibilities. Both types of thinking are typically required to solve challenging problems. The differences between the two approaches have been debated by scientists, but current experiments and brain-imaging studies indicate that they are separate abilities requiring truly different brain states. Test subjects are more likely to solve puzzles using insight thinking when they display brain activity in the anterior cingulate cortex. This activity is associated with the widening of attention, making the brain more open to distraction and to detecting weaker connections. Positive mood appears to shift the brain towards the state required for insight thinking. In experiments where subjects are shown a humorous video…

The Language Comprehension Continuum

by  • 

Below is an example of communication error — Penn and Teller use strong emotional language and delivery to hide the true meaning of the message. In context — a pretty young woman anxiously and passionately asking individuals at a faire to protect the environment — signing the petition makes sense. People sign many petitions. And the more people sign (or the more signatures they see on the petition), the more likely others sign as well. A woman, seemingly in distress over an environmental problem, inspires an emotional reaction — people want to help. We have a built-in social value system that encourages this kind of behavior. And finally there’s a strong p-prim that all chemicals are bad — so just hearing a chemical compound in a petition gets a response from the crowd. The result? On the language comprehension continuum, these faire goers didn’t do so well…

Words, Language, Influence, & Design

by  • 

I’ve been thinking a lot lately about the power of language. Sure, there have been a lot of news relating to language (election, after all, is only a few months away): legitimate rape is one example of powerful words/phrases in the news. But I would like to briefly explore how words and language can influence the design and use of a product. Language Development It might be interesting to start really early (or to look to unusual cases of individuals without language). The following program by RadioLab does a wonderful job of introducing language and the development of comprehension: Words that Change the World. This half-hour audio show presents the work of Susan Schaller, Charles Fernyhough, Elizabeth Spelke, and James Shapiro. Susan describes a case of a deaf 27 year old man who was never taught language and his journey to comprehension. Charles describes an experiment where babies, kids, and rats are asked to find items in a blank room after a brief disorientation. He discovers that language is essential to linking concepts in our brain. Elizabeth explores the benefits of language farther. And James, a Shakespeare scholar at Columbia University, talks about the use of language to communicate complex…
