semantics

There are several questions about asking how to make a div editable. However one could just use a textarea or input field and make those disabled or readonly. I would guess this would yield better semantics. Even the example given at MDN looks like a plain old input field to me. So why would I use an editable div? What are its advantages over textareas and input fields? I just had a look at an example I found in the tag wiki contenteditable . Is the advantage, that I can use markup inside an editable div, but not inside a textarea or an input field? Wouldn't it then be more semantically

Closed . This question needs to be more focused . It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post . Closed 5 years ago . When processing text, why would one need a tokenizer specialized for the language? Wouldn't tokenizing by whitespace be enough? What are the cases where it is not good idea to use simply a white space tokenization? Tokenization is the identification of linguistically meaningful units (LMU) from the surface text.

ISO IEC 14882-2011 §5.7/5 States: If both the pointer operand and the result point to elements of the same array object, or one past the last element of the array object, the evaluation shall not produce an overflow; otherwise, the behavior is undefined. This section is used here on stackoverflow from time to time. For instance to argue why the increment of a pointer to nullptr is UB like here . It is then interpreted as, having a pointer that does not point to an element of an array object. Is undefined behaviour. However, when I read this I understood it to refer to the evaluation of the

Suppose you have this code: Map<Foo, Bar> map = new HashMap<Foo, Bar>(); Foo foo = new Foo(); Bar bar = new Bar(); map.put(foo, bar); Bar barReturned = map.get(foo); Does Java require that barReturned == bar ? That is, does Java require that barReturned be the same instance as bar ? If not, what semantics are expected? The Javadoc suggests that barReturned == bar must be true, but I'm not 100% sure: V get(Object key) Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key. More formally, if this map contains a mapping from a key k to a value

I want to write a basic semantic web crawler using Python, I know that semantic apps use RDF files, but what else? I have some Python RDF modules installed and I started learning how they work. Could you introduce me to the technologies and techniques used in a semantic application?

I am recently working on using nltk to extract relation from text. so i build a sample text:" Tom is the cofounder of Microsoft." and using following program to test and return nothing. I cannot figure out why. I'm using NLTK version: 3.2.1, python version: 3.5.2. Here is my code: import re import nltk from nltk.sem.relextract import extract_rels, rtuple from nltk.tokenize import sent_tokenize, word_tokenize def test(): with open('sample.txt', 'r') as f: sample = f.read() # "Tom is the cofounder of Microsoft" sentences = sent_tokenize(sample) tokenized_sentences = [word_tokenize(sentence) for
