semantics

问题 Tuple elements may have side-effects, and some of them may depend on others. Consider this program: fn main() { let mut v = vec![1, 2]; match (v.pop(), v.pop()) { (Some(z), Some(y)) => println!("y = {}, z = {}", y, z), _ => unreachable!(), } } Does it output y = 1, z = 2 or y = 2, z = 1 ? A few rounds on the Rust Playground suggests the former on stable 1.32.0, but maybe it would change if I ran it more times, recompiled the compiler, changed compiler versions, etc. Is there a documented

问题 Is it possible to use WordNet to rewrite a sentence so that the semantic meaning of the sentence still ways the same (or mostly the same)? Let's say I have this sentence: Obama met with Putin last week. Is it possible to use WordNet to rephrase the sentence into alternatives like: Obama and Putin met the previous week. Obama and Putin met each other a week ago. If changing the sentence structure is not possible, can WordNet be used to replace only the relevant synonyms? For example: Obama met

问题 I'm currently using p tags to surround form groupings (e.g. label, input and error message)... p tags are what I've used for years but I'm having a bit of an issue as p tags cannot contains divs etc ... so I'm considering using the 'section' tag to break up the form "sections" :)... I'm look for some feedback if u guys think the use of this tag in this context is semantically/functionally appropriate... Forms for me as a web dev are 90% of my day so Really appreciate your thoughts and

问题 Let's say I have a list of articles on a preview page of a blog. I want the whole area of each entry to be clickable. In HTML5 this is a possible solution with valid markup: <a href="details/mypost"> <article> <header> <h1>My Post</h1> </header> <p>This is just the teaser. Read more here …</p> </article> </a> My questions are: Is this semantically a link or an article or somehow both regarding the w3 defintion? How is this content read by search engines and screen readers? Is it just a link

问题 Punning (which was introduced in OWL 2 DL) allows one to give the same name (IRI) to a Class and an Object Property (see Association Example). Can I use this way of meta-modelling to attach attributes on a relation? For instance, the relation drives connects Person and Vehicle . I want to specify the velocity with which the Vehicle is driven, and this property belongs on drives . Punning allows me to model drives as an association class by specifying both a class and an object property named

问题 input: phrase 1, phrase 2 output: semantic similarity value (between 0 and 1), or the probability these two phrases are talking about the same thing 回答1: You might want to check out this paper: Sentence similarity based on semantic nets and corpus statistics (PDF) I've implemented the algorithm described. Our context was very general (effectively any two English sentences) and we found the approach taken was too slow and the results, while promising, not good enough (or likely to be so

问题 I am going to attend the Instance Matching of OAEI, now I need to make my results to Alignment Format. In order to achieve it, I have learned official tutorials.(link:http://alignapi.gforge.inria.fr/tutorial/tutorial1/index.html). But there are many differences between the method taught and the method I want. In other words, I can't understand the API. This is my situation: I have 2 rdf file(person11.rdf and person12.rdf respectively.data link is http://oaei.ontologymatching.org/2010/im/index

问题 I'm using OpenNLP for data classification. I could not find TokenNameFinderModel for disease here. I know I can create my own model but I was wondering is there any large sample training data available for disease? 回答1: You can easily create your own training data-set using the modelbuilder addon and follow some rules as mentioned here to train create a good NER model. you can find some help using modelbuilder addon here. It is basically, you put all the information in a text file and the NER

问题 I'm a beginner in SPARQL and I'm working on this endpoint http://spcdata.digitpa.gov.it:8899/sparql. I'd like to join data from the DBpedia graph.
