问题 I need to validate the Name of a SQL column, which is created programmatically... There whould be 2 validation rules: The Name shouldn't be a C# keyword The Name shouldn't be a SQL keyword (SQL Server 2008 R2) The solution for 1st rule it's nice: The CSharpCodeProvider class has the IsValidIdentifier method which makes the implementation of validation easy. (ex: string myColumnName = "blabla"; var isValid = _cSharpCodeProvider.IsValidIdentifier(myColumnName); ) The solution for 2nd rule it's

问题 I've seen two approaches to building parsers in Scala. The first is to extends from RegexParsers and define your won lexical patterns. The issue I see with this is that I don't really understand how it deals with keyword ambiguities. For example, if my keyword match the same pattern as idents, then it processes the keywords as idents. To counter that, I've seen posts like this one that show how to use the StandardTokenParsers to specify keywords. But then, I don't understand how to specify

问题 Which tools would you recommend to look into for semantic analysis of text? Here is my problem: I have a corpus of words (keywords, tags). I need to process sentences, input by users and find if they are semantically close to words in the corpus that I have. Any kind of suggestions (books or actual toolkits / APIs) are very welcome.

问题 Strange question but my boss is a touch old school and has insisted in our coding standards that we do not use C# shorthands for system types, he likes us to use the full system name. He likes things to be verbose and I happily comply with the standard. However, something which after several months has started to grate on me is the fact that visual studio does not like to comply with the standard when completing code. So if I type: KeyValuePair<Int32, Object> MyValue = new Visual studio will

问题 I need to extract the meta keywords from a web page using Python. I was thinking that this could be done using urllib or urllib2, but I'm not sure. Anyone have any ideas? I am using Python 2.6 on Windows XP 回答1: lxml is faster than BeautifulSoup (I think) and has much better functionality, while remaining relatively easy to use. Example: 52> from urllib import urlopen 53> from lxml import etree 54> f = urlopen( "http://www.google.com" ).read() 55> tree = etree.HTML( f ) 61> m = tree.xpath( "/

问题 I can't seem to find any rock solid documentation on setting keywords for adMob ads via XML or Java. I've tried the methods seen in this thread, but have failed in both respects. My failures for each case are below. When trying to use methods setKeywords(), setSearchQuery(), or requestFreshAd() from the AdView class, it's like Eclipse doesn't recognize that those methods are part of the AdView class. Could I be instantiating this class improperly? My java code is below: import com.google.ads

问题 If I got the C99 restrict keyword right, qualifying a pointer with it is a promise made that the data it references won't be modified behind the compiler's back through aliasing. By contrast, the way I understand the const qualifier is as compiler-enforced documentation that a given object won't be modified behind the back of a human being writing code. The compiler might get a hint as a side effect, but as a programmer I don't really care. In a similar way, would it be appropriate to

问题 I wanted to see if it was possible to define new keywords or, as they're called in WAT's Destroy All Software talk when discussing Ruby, bare words, in Python. I came up with an answer that I couldn't find elsewhere, so I decided to share it Q&A style on StackOverflow. 回答1: I've only tried this in the REPL, outside any block, so far. It may be possible to make it work elsewhere, too. I put this in my python startup file: def bareWordHandler(type_, value, traceback_): if isinstance(value,

问题 Let's say I have a list of domain names that I would like to analyze. Unless the domain name is hyphenated, I don't see a particularly easy way to "extract" the keywords used in the domain. Yet I see it done on sites such as DomainTools.com, Estibot.com, etc. For example: ilikecheese.com becomes "i like cheese" sanfranciscohotels.com becomes "san francisco hotels" ... Any suggestions for accomplishing this efficiently and effectively? Edit: I'd like to write this in PHP. 回答1: Ok, I ran the
