search for: recency

I did some digging and found a thread from 2011 talking about how to subclass Xapian::PostingSource in order to incorporate the date or recency of a document in its weighting: http://thread.gmane.org/gmane.comp.search.xapian.general/8849/focus=8856 As in that thread, I want to be clear that I don't want to sort by date, but rather incorporate date information into the score by which I sort the results. I may be able to stumble arou...

I was thinking about this some more: Is there a reason I can't just weight by some function of recency at indexing time? $weight = get_weight_based_on_recency(...); $tg->index_text($txt,$weight); If I wanted to allow the user the option of searching either in recency-weighted mode or not, I could index each document into 2 different databases, one with and one without. This avoids having...

Hi Hemant, Let's take it one step at a time. Save this code as "qdrfm.R" in your R working directory: It includes the comments I added last time and fixes a bug in the recency scoring. qdrfm<-function(x,rbreaks=3,fbreaks=3,mbreaks=3, date.format="%Y-%m-%d",weights=c(1,1,1),finish=NA) { # if no finish date is specified, use current date if(is.na(finish)) finish<-as.Date(date(), "%a %b %d %H:%M:%S %Y") x$rscore<-as.numeric(finish-as.Date(...

I seriously doubt that you are running the code I sent. What you have probably done is to run your data, which has a different date format, without changing the breaks or the date format arguments. As you haven't provided any example that shows what you are doing, I can't guess what the problem is. Jim On Mon, Oct 9, 2017 at 9:40 PM, Hemant Sain <hemantsain55 at gmail.com> wrote:

Hello, I am facing a problem in drawing heat map using R. I have a 70X3 matrix and I want to draw a heat map with 1 coloumn on X axis another on Y axis and want to show the value of 3rd coloumn using heat colours. Could you please help me with this . Thank you . Regards, Sumit [[alternative HTML version deleted]]

Hello, I'm attempting to plot out a series of bar charts of recency, frequency and monetary (RFM) scores using recency as a conditioning variable so we can see the details of the FM components. My dataset looks like this: rfmCellPop{rfm_score, orecency, ofrequency, omonetary, cellpop} Where rfm_score is the composite score (cellID), oRecency, oFrequency and oMo...

It depends on the weighting formula you're using (and the parameters set for it), but si...

hi everyone, I am planning on creating a local SAN via NFS(v4) and several redundant nodes. I have been using DRBD on linux before and now am asking whether some of you have experience on on-demand network filesystem mirrors. I have yet little Solaris sysadmin know how, but i am interesting whether there is an on-demand support for sending snapshots. I.e. not via a cron job, but via a

Hello, I have 2 servers I'm synchronizing using rsync, I have a situation where I : 1. rsync from rnd-dev2 to rnd-dev1 2. change the rsynched file on rnd-dev1 3. rsync from rnd-dev2 to rnd-dev1 again 4. File gets overridden on rnd-dev1 over though it has newer change time then file on rnd-dev2. here is the bug(?) reproduction: [root@rnd-dev1 test_rsync]# rsync --version rsync version
