104 results for semantic web search engines

APR 13th 2007

It seems as though nothing short of a new buzzword can stop the burst of activity in the vertical search market, and who are we to complain? Vertical search engines differ from their horizontal brethren (who attempt to index the Web as a whole) by focusing on a single topic or niche about which to index information from the Web. Often, a VSE can deliver results with much greater relevancy and accuracy than major horizontal players like Google, Yahoo, and Microsoft.

This entry is a response to I will never support the Semantic Web by Brian of d'bug.

I'm getting tired of reading about how the Semantic Web is some kind of pipe dream that will never be realized. The Semantic Web is completely and entirely within our technological reach. People may have been given the impression that we cannot create the Semantic Web because of its complexity, the number of years it has been in development, or even the unanswered questions that still exist for certain problems we will face. These are valid reasons to doubt our progress, but progress is certainly what we are making.

I recently read on Network World that Gartner's David Mitchell Smith said "There are a lot of constituencies trying to hijack the term Web 3.0." I don't think I like Web 3.0 just yet, do you? I agree with the Gartner representative that Web 3.0 wreaks of marketing hype, and in my opinion it is a race by people that felt left behind by the Web 2.0 movement. Vendors pushing the term Web 3.0 are advocating the rise of the Mobile Web, virtual worlds, and the Semantic Web. I agree that all of these technologies will take rise, but I don't agree that we should call that era "Web 3.0."

Today we actually have a certain number of tools to add meaning to the information that we drop all over the Web. Adding a comprehensible meaning to computers, allowing them to help us better organize things. That's the big idea behind the Semantic Web, an idea which appears more and more obvious to us everyday. In this field, we already have many advanced technologies, starting with those offered by the W3C itself: XML, RDF, OWL, etc.

Image credit: Node GardensTo begin with, there is a very simple idea: Websites should themselves indicate their changes to the search engines. I've already touched upon the subject in the previous part of this series, right now search engines have a reversed approach which consists of crawling the Web constantly looking for the slightest modification. Don't you think it's silly? Think about the number of Web pages to visit, imagine the cost to get the lowest frequency between each visit. Consequently, it seems difficult to consider the development of new search engines today. Nevertheless, the advent of the Semantic Web should lead to their multiplication, in a vertical way, while search engines are getting specialized more and more in specific fields.

Unlike traditional search engines, which crawl the Web gathering Web pages, Semantic Web search engines index RDF data stored on the Web and provide an interface to search through the crawled data. Below is a list of Semantic Web search engines that are currently under development.

SwoogleSwoogle describes itself as being the search engine for the Semantic Web. Swoogle crawls the web looking for RDF documents. At this time Swoogle offers the these services:

  • Search ontologies and instance data
  • Search terms (URIs that have been defined as classes and properties)
  • Provide metadata of Semantic Web documents
  • Support browsing the Semantic Web
  • Archive different versions of Semantic Web documents

This post is a complement to the grassroots vs. ivory towers discussion. In the previous post, James mentioned two trends of realizing the dream of the Semantic Web. While the grassroots way encourages the wider adoption of the Semantic Web, the ivory-tower way stimulates the construction of Semantic Web standards. Besides all of these, these two sides indeed play different roles in weaving the Web — the destiny of web evolution.

For just about every area of research there exists documents online describing background information or techniques to accomplish a task in that domain of research. These documents are often referred to as white papers, provided their content is of technical or research orientation. The information held within white papers is essentially accessible by humans only because machines are not able to read and comprehend text in the same way humans can. If machines were able to read white papers and extract information in the same way humans can we would be able to store each fact and piece of knowledge from the documents. This method of indexing would facilitate much more detailed searches, allowing users to search by topic, theory, conclusion, methods, citations, references, etc.

Semantic search has two legs

Published 10 years ago by Yihong Ding

The discussion of semantic search has gradually become popular. Just not long time ago, semantic search was thought to be barely a little bit more than a dream. At present, optimistic researchers have started to believe its possibility in the near future. Very recently at Read/WriteWeb, Dr. Riza C. Berkan, the CEO of Hakia (a company declared to perform "semantic search"), posted an article about semantic search that attracted much attention. Despite of agreeing with the post, here are more thoughts about semantic search.
