A blog is a journal posted on a website with entries about any subject under the sun. In the past couple of years, blogging has become hugely popular with the release of software that allows even the most computer illiterate cyber-scriber to publish their muses at the push of a button. Now with more than 2.5 million active blogs, the 'blogoshere' is fast becoming an impenetrable mess.
The only way to search for a blog is to enter a single keyword or phrase, such as 'physics' or 'origin of life', into a special search engine. This would give you every blog that contains this phrase regardless of its relevance. For web search in general, Google gets around this by analysing the structure of the web. For example, if one page is pointed to by many others, Google assumes it is more useful and gives it a higher ranking. But without a similar 'structure' in the blogosphere, search engines are powerless to improve their results.
But Steve Cayzer, a software engineer at Hewlett Packard's lab in Bristol, UK, reckons he's got the solution. He calls it semantic blogging - automatically classifying a blog according to its content rather than by keywords or its links to and from it.
Working with William Kong at Imperial College London, Cayzer has designed additional feature into a typical blog-publishing program called Blojsom. Before a blog entry is posted on the web, the program searches the text for words on an internal list called an ontology. This is a bit like a cross between a dictionary and a thesaurus that links together common concepts. For example, a blogger might discuss Jupiter in detail without even mentioning the keyword 'astronomy'. Cayzer's program would ensure that the blog is listed under astronomy as well as other categories such as 'planets'.
Having analysed this content and assigned appropriate categories to the entry, it checks with the blogger before the entry is submitted.
Because it is automatic, this simple categorisation process has the potential to transform blogs, says Cayzer. Usually blogs are viewed with the most recent entries first. The new search tool could allow people to view them in ways such as by subject or by popularity.

надо бы сразу "психосемантический" везде подставлять, и "персональные онтологии". и, конечно же, "динамическое конструирование смыслов множественными субличностями".
