semantics

问题 I'm using sfDoctrineAllowPlugin. I need form which has Twitter's Bootstrap semantics. I looked into template and I found, that there is only $form , which is a <table> . How can I format it in my way? I don't want to use table, rows and cols. 回答1: There are plenty of render* functions available to display each item in your form. renderRow renderLabel render renderError etc ... But you can also define a decorator (a custom sfWidgetFormSchemaFormatter ) for your form to define the way each item

问题 Can we model an object property to be recursive in owl? If not is there any work around? E.g. I want to define workflow as a class in owl. Task and getSubTasks are class and object property in my ontology respectively. I want to model workflow as combination of task and getSubTasks fetched recursively. 回答1: It sounds like you want to declare that getSubTasks , or some superproperty of it, is a transitive property, which you can do in OWL. E.g., if you have a class Task , a property

问题 I am doing semantic analysis in bison and i want to use multiple attribute associated with a token. A related part of my code is: %union semrec { int Type; char *id; } %start prog %token <id> tIDENT Here, i can only use the "id" attribute witht the tIDENT token. I also want to associate the "Type" attribute with tIDENT token. To do this, i tried the following: %token <id> tIDENT %token <Type> tIDENT But it gives me a redeclaration warning for token tIDENT. I also tried the following: %token

问题 I'm supposed to take two sentences each time and compute if they are similar. By similar I mean, both syntactically and semantically. INPUT1: Obama signs the law. A new law is signed by Obama. INPUT2: A Bus is stopped here. A vehicle stops here. INPUT3: Fire in NY. NY is burnt down. INPUT4: Fire in NY. 50 died in NY fire. I don't want to use ontology tree as a soul. I wrote a code to compute Levenshtein distance (LD) between sentences and then decide if the 2nd sentence: can be ignored

问题 I am trying to load a view controller where the accelerometer is moving an image view. the error in the title shows and the app crashes upon view loading. - (void)collsionWithWalls { CGRect frame = self.Mover.frame; frame.origin.x = self.currentPoint.x; frame.origin.y = self.currentPoint.y; for (UIView *image in self.wall) { if (CGRectIntersectsRect(frame, image.frame)) { // Compute collision angle CGPoint MoverCenter = CGPointMake(frame.origin.x + (frame.size.width / 2), frame.origin.y +

问题 I am trying to use antlr4 to write some error checking for my simple grammar. The grammar itself is constructed by functions. ie FUNCTION hello (n){ ...... } FUNCTION main (n) { ...... } I am not sure how it suppose to catch specific errors such as missing function name , or missing main function Here is what my ErrorListener looks like import org.antlr.v4.runtime.*; import org.antlr.v4.runtime.tree.*; public class SimpleErrorListener extends BaseErrorListener { @Override public void

问题 What I am interested to know is if there is a shorter way of achieving the following: App.Plugins = App.Plugins || {}; App.Plugins.SomePlugin = App.Plugins.SomePlugin || {}; App.Plugins.SomePlugin.Models = App.Plugins.SomePlugin.Models || {}; App.Plugins.SomePlugin.Views = App.Plugins.SomePlugin.Views || {}; App.Plugins.SomePlugin.Collections = App.Plugins.SomePlugin.Collections || {}; As far as I know, this format is fine, please someone let me know if I'm mistaken, I'm just wondering if

问题 I am trying to develop/design a main menu/site map for our website. The brief is that the menu should look like a directory tree and each item on the menu should either expand to reveal more menu items or link to another page on the site. On top of this, every item should have the functionality to be added to the sites "Favourites" application, so that every user can more quickly find items that are buried deep within the menu structure. Because of my insane OCD to make sure that everything

问题 Can any one please point me to some simple examples of semantic tagging and querying semantically tagged documents in MarkLogic ? I am fairly new in this area,so some beginner level examples will do. 回答1: When you say "semantically tagged" do you mean regular XML documents that happen to have some triples in them? The discussion and examples at http://docs.marklogic.com/guide/semantics/embedded are pretty good for that. Start by enabling the triple index in your database. Then insert a test

问题 When do I put headings inside a header element? I can't understand it, sometimes it seems to me that each heading has to be between header tags. Let's take this sidebar as example : How to code it? <aside> <header> <h1>How to format</h1> </header> </aside> or <aside> <h1>How to format</h1> </aside> 回答1: See the specification of the header element: A header element is intended to usually contain the section's heading (an h1–h6 element), but this is not required. The header element can also be
