Hi all, Although I sent the mail to Piotr, the author of FSelector, it should be better to ask here to let others know.

Greetings! I loose all my metadata after concatenating corpora. This is an example of what happens: > meta(corpus.1) MetaID cid fid selfirst selend fname 1 0 1 11 2169 2518 WCPD-2001-01-29-Pg217.scrb 2 0 1 14 9189 9702 WCPD-2003-01-13-Pg39.scrb 3 0 1 14 2109 2577 WCPD-2003-01-13-Pg39.scrb .... .... 17 0

Hola, estoy intentando calcular la ganancia de información para una serie de variables (series temporales con distinta longuitud, ej: Presion Arterial, Frecuencia cardíaca,...) en relación con una variable binaria (0:paciente no muere; 1:paciente muere). Para ello voy a usar la función information.gain de la libreria FSelector. Sabeis si es posible calcular la ganancia de información para

This might be an interesting option for some of you!

I'm using text miner (the "tm" package) to process large numbers of blog and message board postings (about 245,000). Does anyone have any advice for how to efficiently extract the meta data from a corpus of this size? TM does a great job of using MPI for many functions (e.g. tmMap) which greatly speed up the processing. However, the "meta" function that I need does not

Hello, I am the maintainer of the stringkernels package and have come across a problem with using S3 objects in my S4 classes. Specifically, I have an S4 class with a slot that takes a text corpus as a list of character vectors. tm (version 0.5) saves corpora as lists with a class attribute of c("VCorpus", "Corpus", "list"). I don't actually need the

My second (and hopefully last) question: is there any more news on indexing Chinese characters and words? Searching online mostly returns results from a decade ago or more, with nothing very conclusive. How close is this to possible? For the time being I'm doing some pre-processing on long strings of Chinese, breaking on punctuation in order to avoid errors. But I have some large corpora of

>From my book on corpus linguistics with R: # (10) Imagine you have two vectors a and b such that a<-c("d", "d", "j", "f", "e", "g", "f", "f", "i", "g") b<-c("a", "g", "d", "f", "g", "a", "f", "a",

This changeset adds byte run reporters for node and value metadata in the hivexml program. This location reporting required several new ABI functions, which required new ABI return types. One benefit to the byte run functions is additional sanity checks, which have revealed new data or parsing errors when run on M57 patents images. An example error: Image: Charlie, 2009-12-11, available at

I need to use entropy based feature selection to reduce term space while doing text classification. Are there any R packages available that would help me do this? I can also make do with chi squared based algorithm, if there are packages for that. Thanks in advance.

Hi, I am doing a project on authorship attribution, where my term document matrix has around 10450 features. Can you please suggest me a package where I can find the feature selection function to reduce the dimensions. Regards, Venkata Satish Basva [[alternative HTML version deleted]]

Hello list I have a problem with classifying traffic from two providers, and about 600 users. I have the following situation: P1-\ | linux | --eth0-| box |-eth1 P2-/ | | P1 and P2 are coming from VLANs. I have 4 type traffic which I want to classify. The traffic is divided as follows: P1 - 100mbit from realm 0x70000 10mbit from realm ! 0x70000

Hi to all, I'm new to this forum and new to R. I have to build a tree classifier that has boolean values as response. When I build the tree with: echoknn.tree <- tree(class ~ ., data=echoknn.train) where "class" is a coloumn of my dataset (echoknn.train) of boolean values, the result is a tree where leaf nodes are numbers in the range [0,1]; but this isn't the result that I

Hi, I''ve been working for a big corporate company as junior system engineer and getting nicely to understand HTB/iproute2/iptables etc, The ordinary users(about 500 users), can pop / smtp / skype out on the network, but I can''t ssh out, cause they blocked the ports. Thought of being clever, I let my home linux listen on port 443 or 110 for ssh connection, but it wont connect, I

Is there any way to discover whether a particular operand of a MachineInst participates in addressing? That is, if the MachineInst references memory, can I tell, given an operand, whether that operand is part of the address calculation for the instruction? Also, is there any reasonable way to get the set of machine instructions to which the output(s) of some machine instruction flows? The
