Sogou Labs

Sogou Labs offers algorithms and experiments including:

  • R-SpamRank: A spam detection algorithm that is based on link analysis by assigning spam values to web pages and semi-automatically selecting potential spam web pages. The algorithm first manually select a small set of spam pages as seeds. Initial R-SpamRank values are propagated through links and distributed among the whole web page set. Download the spam detection algorithm as *.pdf.

After sorting the pages according to their R-SpamRank values, the pages with high values are selected. Our experiments show that the algorithm is highly successful in identifying spam pages, which gains a precision of 99.1% in the top 10,000 web pages with the highest R-SpamRank values.

    Gordon, I have just submitted my website by using your link above and then filling out the submission form.

    When I clicked on the send button, there was no reply to confirm it had been sent.

    Is this normal because you said to only submit once.

    Regards. Neil
