extraction

问题 Is there an algorithm that can be used to extract simple sentences from paragraphs? My ultimate goal is to later run another algorithm on the resulted simple sentence to determine the author's sentiment. I've researched this from sources such as Chae-Deug Park but none discuss preparing simple sentences as training data. Thanks in advance 回答1: I have just used openNLP for the same. public static List<String> breakIntoSentencesOpenNlp(String paragraph) throws FileNotFoundException, IOException

问题 Would it be possible to extract scores and goals for/against with python from a webpage like: http://www.uscho.com/standings/division-i-men/2011-2012/ ? My problem lies in the fact that the tables are structured funky. Is there any resource that could help me out with my problem? 回答1: The example web-page is pretty easy to parse with lxml. Here's a basic script to get you started: from urllib2 import urlopen from lxml import etree url = 'http://www.uscho.com/standings/division-i-men/2011-2012

问题 Is it possible to get the locations of words using PDFBox, similar to "processTextPosition"? It seems that processTextPosition is called on single characters only, and the code that merges them into words is part of PDFTextStripper (in the "normalize") method, which does return the location of the text. Is there a method / utility that extracts the location as well? (For those wondering what the motivation is - the information is actually a table, and we would like to detect empty cells)

问题 In C++, is there a function in the fstream library (or any library) that allows me to read a line to a delimiter of '\n' without extracting? I know the peek() function allows the program to 'peek' at the next character its reading in without extracting but I need a peek() like function that does that but for a whole line. 回答1: You can do this with a combination of getline , tellg and seekg . #include <fstream> #include <iostream> #include <ios> int main () { std::fstream fs(__FILE__); std:

问题 I'm using the Resharper trial and VS2008. Is it possible to extract all classes from one file into a separate file? I'm able to do this using Resharper but it only seems to work for individual classes. This is to be used on a file that was auto-generated that is 65,000 lines long. 回答1: If you're using ReSharper 5, on the solution explorer, press Ctrl+Shift+R to invoke the Refactor menu (or alternatively right-click and locate it) and select "Move Types into Matching Files" 回答2: For those that

问题 I am going to create a self extracting archive but I have got a problem connecting with the default path of the extraction. I would like to extract my files in the same path as the self-extraction archive program. Unfortunately, the files are extracting in another path (C:\Users\computer\AppData\Temp\IXP000.TMP). Is it possible to set the path? 回答1: I can't find any direct way to do this with IExpress, but there is a trick we can apply. But first I'll point out that this is really easy with

问题 There seems to be a lot of questions about extracting a title from a PDF (using its metadata). However, the large majority of the titles do not seem to exist in the metadata. I found this out when using http://pybrary.net/pyPdf/pythondoc-pyPdf.pdf.html . Is there anyway to actually retrieve the in text title from a pdf? I tried to export to a text file then search but there is no consistent formatting. Is there any way to export the pdf to a document with its formatting, then check for a font

问题 If I use the ecdfplot() function of the latticeExtra package how do I get the actual values calculated i.e. the y-values which correspond to the ~x|g input? I've been looking at ?ecdfplot but there's not discription to it. For the usual highlevel function ecdf() it works with the command plot=FALSE but this does not work for ecdfplot() . The reason I want to use ecdfplot() rather than ecdf() is that I need to calculate the ecdf() values for a grouping variable. I know I could do this handish

问题 I got the following string: String line = "#food was testy. #drink lots of. #night was fab. #three #four"; I want to take #food #drink #night #three and #four from it. I tried this code: String[] words = line.split("#"); for (String word: words) { System.out.println(word); } But it gives food was testy , drink lots of , nigth was fab , three and four . 回答1: split will only cuts the whole string at where it founds a # . That explain your current result. You may want to extract the first word
