similar to: Need help as Pl2 tests not performing as expected

Hi olly, I rewrote the test for PL2 after adding code to deal with negative weights. It passes on all backends other than inmemory . I see a different value of weight for inmemory backend. The code to calculate the lower bound is implemented in init().Please can I get some help with this ? -Regards -Aarsh -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello guys.I am working on implementing the PL2 weighting scheme of the DFR framework by Gianni Amati. It uses the Poisson approximation of the Binomial as the probabilistic model (P), the Laplace law of succession to calculate the after effect of sampling or the risk gain (L) and within document frequency normalization H2(2) (as proposed by Amati in his PHD thesis). The formula for w(t,d) in

Hello guys.I just realized that Ive not set the weighting scheme to PL2 in the tests for PL2 and so a default weighting scheme of BM25 is used. I am extremely sorry for this and am updating the tests by setting the weighting scheme to PL2. -Regards -Aarsh -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello guys.I have added various tests to the PL2 pull request.They are working fine. Have also added PL2 to the registry and to the java and csharp makefiles.Please do let me know what you'll think.Other than the collection frequency problem discussed on IRC, it is ready.Am now beginning work on adding code and tests for DPH to the same branch. -Regards -Aarsh -------------- next part

Hey guys,hi.:) I've finished implementing the PL2 scheme . The bounds I have implemented for it are as good as I could, given the nature of the scheme and my mathematical skills.However,tight bounds for other named DFR schemes will be easier to implement because their forumlas are quite simpler compared to PL2 . Will send in a pull request in a couple of days once I'm done with the tests

Hello there, I'm trying to do lots of plots in one for-loop. But somehow ggplot does not evaluate arguments as expected. Here is an example: library(lattice) library(ggplot2) pl <- list() pl2 <- list() cDat <- as.data.frame(cbind(x1=0:100,x2=0:10,x3=1:20)) for(obs in c("x1", "x2")) { pl[[obs]] <- xyplot(cDat[,obs] ~ cDat[,"x3"], main=obs)

Dear all, let consider the following function: Fun1 <- function() { library(lattice) plot1 <- 1:10~1:10 pl1 <- xyplot(plot1) return(pl1$call$x) } In R 2.5.0 (or older version) we have > Fun1() plot1 but starting from R 2.5.1 until the latest R 2.8.0 we obtain instead > Fun1() NULL because pl1$call seems to be equal to xyplot() without arguments. Something like

Hey guys hi.I am trying to understand how Xapian works .I read the Theoretical Background to Xapian doc and the report by Salton and Jones.I still cant seem to understand how Eset works How exactly does Xapian add terms to expand a query ? Assuming we have a list of the k most important terms, how do we decide which term to add to the query and will be in context with the query ? And to decide r

Hello guys,I have added code for tfidf to the weight.cc file in omega/ . Here is the patch : - https://github.com/aarshkshah1992/xapian/commit/5ff41a15f574e6780cc61e67e7f3da3d97ff4ec8 It compiles well and I think it'll work well. Here's the link to the documentation file omegascript.rst where I've added tfidf.

I am suffering for slow searching performance on Xapian. I am using Xapian for indexing about 150,000,000 documents. It was implemented in C++; The performance of searching was not that fast. e.g. Searching a query, which includes about 20 terms, needs 2 secs avg. For searching, I followed such steps: 1. construct a QueryParser for certain string 2. parse the query to get a Xapian::Query
