1. Artificial intelegence is the "moving frontier" because it can lead to high improvements in technology to make life easier for mankind. It can makes computers percieve things and help get more logical answers.
2. The disadvantages to AI is that it shortens peoples attention span and it makes us rely more on technology to do our daily jobs. An alternative might be to onhly rely on technology for those things which are to tedious to do by ones self. Although withb the world we live in today, that might be almost impossible.
4. Early machine translation didn't work so well because it translated works literally. Phrases which weren't ment as they were said, came back in weird translations. As an example, "out of sight, out of mind" because "invisible idiot." Basically, a fail.
5, The reason it is hard for a robot to understand the meaning of "time flies like an arrow" is because the meaning of this isn't a literal one. The meaning is in between the lines and a robot can't think like humans. The quote means that time goes by so fast, that it can be compared to an arrow. Time flies by without us even realizing it.
6. Syntax is the arrangement of a sentence while semantics is the underlying meaning of a word. It is impossible for a sentence to have proper syntax but not semantics. The sentence has to include both to have a proper sentence.
7. A knowledge base contains a system of rules for determining and changing the relationship among facts in a database, while a expert system is designed to replicate the decision-making process of a human expert. It requires a knowledge base so that when a robot is trying to make ethical decisions, it can look to the knowledge base and make sure it isn't going against any morals.
9. What made machine vision so challenging was the fact that it took alot of memmory processing power to make sence of the image.
14. The main difference between a robot and a desktop computer are the input and output peripherals. A computer sends output through printers, while a robot sends output through arm movements and gestures.
