opengraph - og:site_name ignored for facebook comments plugin? -

-

i'm using facebook's comment plugin, , have point page open graph tags set up.

when user makes comment on page using plugin, of og tags used facebook in wall post, except og:site_name, should go in caption of link instead domain of site appearing.

example html:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml"> <head> <title>my title</title> <meta property="og:type" content="article" /> <meta property="og:site_name" content="my site name" /> <meta property="og:title" content="my title" /> <meta property="og:url" content="http://www.example.com" /> <meta property="og:image" content="http://www.example.com/some_image.png" /> <meta property="og:description" content="this description" /> <meta property="fb:app_id" content="fb_app_id" /> </head> <body> ..... </body> </html>

but here's end seeing on facebook:

example

note caption says "www.example.com" instead of "my site name" expected see there.

anyone know why og ignoring tag?

thanks in advance,

dw

not fix possible reason.

there's opened issue in facebook bug db: incorrect site name appearing in shared links on facebook

unfortunately, seems low priority issue.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
