semantics

How much of the concepts conveyed in natural language is RDF/OWL able to represent? I'm still learning RDF and other semantic technologies, but as I currently understand it, information is typically represented as triples of the form (subject,predicate,object). So I can imagine how the sentence "Bob has a hat" might be represented. However, how would you represent a more complicated sentence like "Bob, over on 42nd street, will have a job at the Mall after the owner approves"? Are there conventions for tags representing nouns/verbs/ownership/causality/tense/etc? Note, I'm not asking how to

I want to know if is there any specific algorithm that can be followed to understand the meaning of a word/sentence/paragraph. Basically, I want to write a program that will take text/paragraph as input and try to find out what its meaning is. And thereby highlight the emotions within the text. Also, if there is an algorithm to understand things, can the same algorithm be applied to itself? It reduces the quest further to a point where we become interested in knowing meaning of meaning OR rather definition of definition. You want Natural Language Processing and Semantic Technology . This is

If the value of the variable x is initially 0, the expression x += x += 1 will evaluate to 2 in C, and to 1 in Javascript. The semantics for C seems obvious to me: x += x += 1 is interpreted as x += (x += 1) which is, in turn, equivalent to x += 1 x += x // where x is 1 at this point What is the logic behind Javascript's interpretation? What specification enforces such behaviour? (It should be noted, by the way, that Java agrees with Javascript here). Update: It turns out the expression x += x += 1 has undefined behaviour according to the C standard (thanks ouah , John Bode , DarkDust , Drew

quick question: is it actually allowed to use the header tag twice? e.g. i have two important head-sections in my header.php where both could have header tag? Yes, but with a catch. The W3 documents state that the tags represent the header and footer areas of their nearest ancestor section. I would recommend having as many as your want, but only 1 of each for each "section" of your page, i.e. body, section etc. From W3 A header element is intended to usually contain the section's heading (an h1–h6 element or an hgroup element), but this is not required. The header element can also be used to

The protege SWRL tab is not available in Protege 4 versions, I have tried both protege 4.1 and protege 4.2. The axiome plugin mentioned to edit the SWRL rules in protege has been said to work only in protege 3 versions. Can anyone tell me plugins or procedure to include the plugin to edit SWRL rules in protege? SWRL rules can be edited in Protégé 4, but not with a nice interface like in Protégé 3. If you go to menu Window -> Views -> Ontology views, there is an option Rules. Select it and add it as a "view", i.e., a rectangle in the current tab. Rules are written like this: parent(?x,?y),

Is there a semantic difference between the terms call stack and thread stack , in Java multithreading? Each thread has its own call stack, "call stack" and "thread stack" are the same thing. Calling it a "thread stack" just emphasizes that the call stack is specific to the thread. Bill Venners calls this the Java stack : When a new thread is launched, the Java virtual machine creates a new Java stack for the thread. As mentioned earlier, a Java stack stores a thread's state in discrete frames. The Java virtual machine only performs two operations directly on Java Stacks: it pushes and pops
