Zemanta is a an interesting European startup that is applying semantic technologies to blogging. Sarah Perez covered the company's launch in March. One can think of Zemanta as an auto-complete function for blogging. As you are typing up a new post, Zemanta's browser plugin fetches related content - images, articles, videos, links - and provides a simple and friendly UI for inserting the related content into your blog. We caught up with Andraz Tori, CTO and co-founder of Zemanta, at the SemTech conference at San Jose last week for an interview.

Today SezWho a universal profile, content discovery, and a sophisticated reputation engine provider, has announced its acquisition of Tejit, a provider of semantic intelligence solutions. The acquisition enables SezWho to provide more precise contextual reputation scores for contributors based on topics of conversation. ReadWriteWeb gives you an in-depth look into SezWho's latest acquisition and how SezWho measures up to the competition.

Tony Sukiennik believes the power of the people trumps the power of the algorithm when it comes to the development of semantic technology. His company, infoGenome, a startup that has been in stealth mode for about four and half years, wants to harness that power by making semantics easy via its innovative drag-and-drop functionality. The i360 software he's developed is essentially the "Mahalo of semantic apps," relying on human knowledge to add meaningful layers of metadata to the information we work with every day. With i360, you can add semantics to everything.

Alright, "semantify" may not be an actual word, but you can probably guess at its meaning: "add a semantic layer to." In this case, we're looking at a small plugin called Triplify that reveals the semantic structures of web applications by converting their database content into semantic formats.

The Economist published a short article about the Semantic Web today, picking up on apps we've covered here many times - like Reuters Open Calais, Twine, Hakia and AdaptiveBlue. But one app right at the end caught my eye, as I'd not heard of it before: Qitera. Its homepage describes it as "a next-generation information engine - a semantic web service that connects everything you know to everything you read." The company is German, but based in San Francisco. Qitera is currently in private beta, so it's hard to know what this app does. But it sounds a lot like Twine.
