Semantics search

Semantics search

There is just too much confusion about so-called “Boolean search” so I’d like to clarify a few basic things: Booleans are simply three LOGICAL OPERATORS: AND OR NOT. In search engines you don’t need the AND because its always assumed by default, so forget about it. That leaves you with two: OR and NOT. The The OR is called a logical disjunction, sometimes an inclusive disjunction…

HTML5 semantic document structure

If your business is like mine, you ve been hearing a lot of HTML5 this and HTML5 that lately. Lots of talk about the Flash killing video element, animations with canvas, geolocation, and much more. In fact, the buzz around HTML5 has been extended to include things that aren t even HTML5 at all. All over the web, people are talking about the new expressive capabilities of…

Semantics definition computer

Semantics definition computer

In programming language theory, semantics is the field concerned with the rigorous mathematical study of the meaning of programming languages. It does so by evaluating the meaning of syntactically legal strings defined by a specific programming language, showing the computation involved. In such a case that the evaluation would be of syntactically illegal strings, the result…

Formal semantics of SQL queries

Formal semantics of SQL queries

The documentation of a database includes its conceptual schema, that formalizes the semantics of the data, and its logical schema that translates the former according to an operational database model. Important engineering processes such as database and program evolution rely on a complete and accurate database documentation. In many cases, however, these schemas are missing…

Semantics meaning in DBMS

Semantics meaning in DBMS

DT: The author of the following quote resists the idea that a primary function of an RDBMS is indeed to manage the meaning of the data, through constraints. If we step back and look at what RDBMS is, we’ll no doubt be able to conclude that, as its name suggests (i.e. Relational Database Management System), it is a system that specializes in managing the data in a relational…

Semantic Encoding

Semantic Encoding

Prefrontal cortical function was examined during semantic encoding and repetition priming using functional magnetic resonance imaging (fMRI), a noninvasive technique for localizing regional changes in blood oxygenation, a correlate of neural activity. Words studied in a semantic (deep) encoding condition were better remembered than words studied in both easier and more difficult…

SPARQL formal semantics

SPARQL formal semantics

Abstract: As of today, there exists no standard language for querying Linked Data on the Web, where navigation across distributed data sources is a key feature. A natural candidate seems to be SPARQL, which recently has been enhanced with navigational capabilities thanks to the introduction of property paths (PPs). However, the semantics of SPARQL restricts the scope of navigation…

Web semantics research topics

Web semantics research topics

Off the top of my head, some topics that I see as trending: Scalable reasoning: reasoning has always been a hot topic in the SW community, but now there is increasing demand for reasoners that can scale into the billions of triples and handle messy data. Distributed reasoning has been a hot topic for a while, as have new languages (like the profiles of OWL), and ways to deal…

Example of semantics

Example of semantics

One part of studying a language is knowing the many meanings of individual words. Here are some examples of words with more than one meaning: A water pill at first glance could be a pill with water in it; but, it is understood to be a diuretic that causes a person to lose water from his body. Crash can mean auto accident, a drop in the Stock Market, to attend a party without…

Define the term semantics

It seems that most of my discussions about “jazz” usually begin and end with opinions and definitions as to what the word actually means. Either people believe jazz to be a specific genre – one that they either like or hate – or they only know that they hate it without really being able to define it. Many view jazz as one thing, or define it as a “style” of one era – traditional…

Static and Dynamic semantics of the Web

Static and Dynamic semantics of the Web

The original perception of the Web by the vast majority of its early users was as a static repository of unstructured data. This was OK for browsing small sets of information by humans, but this static model is now breaking down as programs attempt to dynamically generate information, and as human browsing is increasingly assisted by intelligent agent programs. The next phase…

Abstrakt The paper investigates the interaction of topic-focus articulation (TFA), word order, and prosody in spoken Czech within the framework of Optimality Theory (OT). After an outline of TFA and of the ways of its expression in Czech, drawn on the backround of the Functional Generative Description approach, I propose an OT analysis of this complicated phenomenon for rudimentary…

From the perspective of a client application, whether a MongoDB instance is running as a single server (i.e. “standalone”) or a replica set is transparent. By default, in MongoDB, read operations to a replica set return results from the primary. Users may configure read preference on a per-connection basis to prefer that the read operations return results from the secondary…
