import - R - Text Mining - Importing a Corpus and keeping the file names in document term matrix -

-

The code shown below allows me to import a series of .txt documents stored in the local area (1 month ago)

Had given R in the folder, to make a corpus, to pre-process it and finally convert it to a document term matrix. The problem I have is that document names are not being imported, instead each document is listed as 'character (0)'

One of my goals is to model the topic on the corpus And therefore it is important that I can relate model names to those models which produce the model.

Is anyone suggesting what has changed? Library ("TM") Library ("Snowball Sea") Setdodi ("C: / User / Document / Dataset /") Corpus & lt; DirSource ("Blog")) MyStopwords & lt #pre_processing; - c (stopwords ("english")) your_corpus & lt; - tm_map (corpus, tolower) your_corpus & lt; - tm_map (your_corpus, removeNumbers) your_corpus & lt; - tm_map (your_corpus, removeWords, MyStopwords) your_corpus & lt; - tm_map (your_corpus, stripWhitespace) your_corpus & lt; - tm_map (your_corpus, delete delete) your_corpus & lt; - tm_map (your_corpus, stemDocument) your_corpus & lt; - tm_map (your_corpus, plaintextdocument) #doucment word matrix myDtm & lt; - DocumentTermMatrix (your_corpus, control = list (wordLengths = c (3, inf) Inspection of myDtm (myDtm)

Here is a debugging session to identify / correct the loss of the file name. The tool line was modified, and the plain text line was commented because these lines provided file information Also, if you check the DS $ reader, you can see that the baseline reader is a plain text document. Avejh makes.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
