Then at the end of December, we'll post a strongTop 100 list/strong - which we'll be promoting over 2009 and opening up at some point for public voting.

Yahoo! SearchMonkey/h2 pimg src="http://www.readwriteweb.com/images/yahoo-purple-logo.jpg" width="140" height="103" border="0" align="left" /In May this year a href="http://www.readwriteweb.com/archives/yahoo_searchmonkey_launches.php"Yahoo! launched an open developer platform for search/a called a href="http://developer.yahoo.com/searchmonkey/"SearchMonkey/a. Yahoo hasn't had the happiest of years, but its willingness to innovate in search is to be commended. As we reported a href="http://www.readwriteweb.com/archives/yahoo_apps_platform.php"at the Web 2.0 Expo/a in April, SearchMonkey is a component of a major overhaul at Yahoo! across all of its properties to "rewire" for the social graph and data portability. SearchMonkey allows developers to build applications on top of Yahoo! search, including allowing site owners to share structured data with Yahoo!, using semantic markup (microformats, RDF), standardized XML feeds, APIs (OpenSearch or other web services), and page extraction./p pWe think this is the best use of Semantic Web by an Internet bigco this year. So for that reason SearchMonkey makes our top 10 list. emRelated: a href="http://www.readwriteweb.com/archives/semtech_making_the_web_searchable_searchmonkey.php"The Story of SearchMonkey/a/em./p h22.

It's fair to say that Powerset has had a great 2008, having been a href="http://www.readwriteweb.com/archives/microsoft_acquires_powerset.php"acquired by Microsoft in July this year/a./p pAt the time of the acquisition, Powerset said that it needed a bigger partner to expand its product beyond its current state of only searching Wikipedia - something we had speculated about when the a href="http://www.readwriteweb.com/archives/rumor_microsoft_powerset.php"rumors of the acquisition first appeared/a. In its own statement, Microsoft stressed how useful Powerset's technology will be for improving Microsoft's own search products and to quot;take Search to the next level.quot; In a href="http://www.readwriteweb.com/archives/does_microsoft_powerset_beat_google.php"our analysis of the deal/a, we noted that it was a quot;bold play requiring exact executionquot; by Microsoft./p h23.

What a change a year brings!

The idea is that publishers can tell Dapper: this is the place on my web page where the title of a movie will appear, now serve up a banner ad that's related to whatever movie this page happens to be about. That could be movies, books, travel destinations - anything. We remarked that the UI for this has grown much more sophisticated in the past year. /p pThe company believes that its new ad network will provide monetary incentive for publishers to have their websites marked up semantically. We think this has plenty of promise, so it makes our year-end list./p h25.

In September we covered a href="http://www.readwriteweb.com/archives/zemanta_releases_major_upgrade.php"a major upgrade to Zemanta's service/a, allowing users to specify the sources they want to see in the suggestions list that Zemanta provides. Users can now incorporate their own social networks, RSS feeds, and photos into their blog posts. As we noted, this makes Zemanta a lot more appealing to established bloggers who are in less need of suggestions and more in need of automation./p pZemanta's API is also being used by startups, including semantic bookmarking service Faviki - which we mentioned in a href="http://www.readwriteweb.com/archives/10_more_semantic_apps_to_watch.php?p=2"our second Watch-list/a.
