Is the following code guaranteed to terminate normally and successfully? #include struct foo_s { union { struct { unsigned a : 10; unsigned : 6; }; struct { unsigned : 10; unsigned b : 6; }; struct { unsigned : 10; unsigned c : 6; }; }; }; int main { struct foo_s f; f.a = 0; f.b = 1; assert(f.a == 0); return 0; } While answering a different question, the possibility was raised…

| Many people don t have a clear idea of what the Semantic Web is. The best informal definition is maybe found in the May 2001 Scientific American article The Semantic Web (Berners-Lee et al.), that saysThe Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation.People…

From a perspective of the theory and practice of programming languages, language elements have semantics. Naming conventions don t. And semantics has nothing to do with fidelity to anything, except perhaps that if an implementation is correct it is sometimes called faithful to the semantics. Beyond that it s hard to generalize because there are so many different styles…

When I first conceived the idea of writing about my research in a way understandable to non-semanticists, I imagined I’d write an attractive new update every two months or so, sharing all my interesting recent ideas in fascinating ways and making everyone who read it wish they had my job. Then reality happened, in which very few of my interesting ideas still make sense after…

While many HTML4 elements have been brought into HTML5 essentially unchanged, several historically presentational ones have been given semantic meanings. Let’s look at and and compare them to the semantic stalwarts and .

I can t fault your tags at all. The only problem is that due to your table being quite complex, assistive technology may not be able to figure out the structure of your table. I was going to recommend using scope but according to W3C there are some inconsistency issues. The row and col values of the scope attribute are currently supported to a large extent by most current versions…

The Semantics of Programming Languages [edit] Semantics, roughly, are meanings given for groups of symbols: ab+c, ab + c , mult(5, 4). For example, to express the syntax of adding 5 with 4, we can say: Put a + sign in between the 5 and 4, yielding 5 + 4 . However, we must also define the semantics of 5+4. If we use arithmetic semantics, 5+4 would be a representation/equivalent(=)…

If you have nearly any tenure in HR, sourcing or recruiting, you’ve probably heard something about “semantic search” and perhaps you would like to learn more. Well – you’ve found the right article. As a follow-up to my recent Slideshare on AI sourcing and matching, I am going to provide an overview of semantic search, the claims that semantic search vendors often make, explain…

Aim To investigate how deep and shallow processing affects memory recall. Method Participants were presented with a series of 60 words about which they had to answer one of three questions. Some questions required the participants to process the word in a deep way (e.g. semantic) and others in a shallow way (e.g. structural and phonemic). For example: Structural / visual processing:…

Let $P_2$ be the conjunction of the finite set of Peano s postulates for second-order arithmetic. These have only one full model, which is the standard model of second-order arithmetic. We know from the incompleteness theorems that, no matter what consistent, effective extension $X$ of $P_2$ we consider, there will be some sentence $\phi_X$ in the language of arithmetic that…

This site introduces ontologies and semantic web, with the emphasis on how ontologies are defined and used for semantic web applications today (more about this site background is here). This tutorial is extracted from the introductory chapter of the dissertation that deals with the applications of ontologies in multi-agent systems - Marek Obitko (advisor Vladimir Marik): Translations…

When people come to your content – the content on your website, for example – can they find what they need? One of the best ways to help visitors find the information they consider most useful is to organize it into behind-the-scenes categories. By categories, I mean more than the kind of categories you might use to organize a blog – say, the boxes you can check in WordPress…

Value semantics for an object indicates that only its value is important. Its identity is irrelevant. The alternative is reference/pointer semantics; the identity of the object is at least as important as the value of the object. This terminology is closely related to pass/copy-by-value and pass-by-reference. Value semantics is a very important topic to consider when designing…

“Semantics” refers to the meaning behind words, sentences, or phrases. This is its general meaning. In technology, even the word “semantics” has more meanings. Semantics, and semantic models, refer to how data is organized within a database to make it more useful for users. So, in technology, semantics have the meaning of “makes sense to the user.” From a purely programming…

In this section, we ll look at categories of states and events. We ll see that these categories are more complicated than categories of things because they are in a sense about things. Without things, there can be no notion of state or event. Part of characterizing a particular state or event category is characterizing what sorts of things it can be about, how many things there…
