r - Creating a data frame from a CSV file with embedded lists -


i'm still rather new r , may have gotten concept of data frames messed up.

but have csv file in following format:

id;year;title;authors;keywords;

where authors , keywords supposed list of strings. e.g.

1;2013;towards dynamic non-obtrusive health monitoring based on soa , cloud;mohammed serhani, abdelghani benharret, erlabi badidi;e-health, diseases, monitoring, prevention, soa, cloud, platform, m-tech;

is there way read csv file r data frame columns authors , keywords built lists of lists? , require me format csv file in specific way?

reading csv following options

articles <- read.csv(file="ls.csv",head=true,sep=";",stringsasfactors=f)

yields authors colum list containing character instances. i'm trying achieve getting list of characters in each field in authors column.

are saying file contains 5 variables (id, year, title, authors, keywords) separated semicolons? then, definition, it's not csv file! remember csv stands comma-separated values. screwed naming such.

you can read arbitrarily-delimited data using read.table:

articles <- read.table("ls.csv", header=true, sep=";", stringsasfactors=false)

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
