SCIENTISTS with the Chinese Academy of Sciences will offer government organizations and Website operators a more intelligent computer tool to discover pornography and lewd material on the Internet.
Last December, Zhang Quan and his colleagues at the CAS Institute of Acoustics developed a system of comprehensive Chinese-character recognition, which could identify porn content on Websites not only by key words but also by syntax and other features of the language.
"The system functions as a search engine," Zhang, chief scientist of the program, told Xinhua news agency yesterday. "You input a Website address and it will automatically open every page on the site and examine words, sentences and paragraphs for pornographic material.
"It is smarter than keyword-based search engines, because it can discern articles which are critiquing porn materials from those which are merely talking dirty," he said.
The system can also highlight ambiguous paragraphs that it can't comprehend for examiners to scrutinize individually, he said.
The CAS official Website and some of its institutes' Websites have already adopted the system for trial use.
"We anticipate that many government organizations and Website operators will find it useful," said Zhang, "and we will soon put the software onto the market."
Scientists also established a database of "pornographic-like" words working as a "searching standard" for the examination.
The software could be used by supervision watchdogs or Websites themselves for real-time supervision of online content.
However, Zhang admitted that the new invention could only sniff out "pornography in written form," and could do nothing about images or audio-visual material.
"We have yet to find an effective way for audio-visual examination, which needs further advanced technology," Zhang said.
In January, seven government departments, including the State Council's Information Office and the ministries of Public Security and Culture, launched a crackdown campaign on porn Websites.
