 Welcome! This first clip of a series of semantic analysis tasks discusses the formal analysis of sentence meaning, from propositional analysis to the conversion of propositions into predications. The exercises are organized from very simple to complex. This first exercise is extremely simple, but it presupposes that you have gone through the e-lecture, predicate logic 1. Well, and this is our task. We have to convert these sentences here first into propositions and then into predications. And the sentences are, Bill is tired, Richard is bet his father and Mary sent John a letter. So let's start with our first example. In our first example we have one proposition, namely Bill is tired. Let's call it P. In this proposition the predicate tired assigns a property to its argument. Hence Bill is assigned the property tired. So we have the simplest form of a predication, tired Bill. Remember that the predicate is always capitalized and its arguments are written in small letters. Here is the second example. Richard is bet his father. Again, the sentence exhibits one proposition. Let's call it Q this time. Richard is bet his father. In this proposition the predicate father of denotes a relationship between the two arguments Richard and Betty. Thus we have a predication where a relationship between the arguments is established. And this relationship depends on the sequence of the arguments. If we reverse the two arguments Richard and Betty, we have a situation where Betty would be Richard's father. And that of course would result in a false proposition because we should assume that Betty is female. Here is our last example. In this sentence Mary sent John a letter. Again, we have a single proposition. Let's call it R this time. Where the predicate send denotes a relationship between its three arguments Mary, John and letter. Nevertheless, it is still a simple predication with one predicate. In this case, we have a three-place predicate. Okay, that's it for now. And here is the summary of our solutions. These were all simple propositions that could be converted into simple predications. The only difference between them was that the number of arguments was different. Tired Bill, a one-place predicate, tired. Father of Richard, Betty. Father of is a two-place predicate. Send Mary, John a letter. Send is a three-place predicate. By the way, the print version of the solution is available on the Virtual Linguistics Campus in the VLC e-lecture library which can be reached via mouse click as soon as you are logged in. Well, thank you and see you again.
