The City of San Francisco too, decided to publish several Datasets. DataSF is a central clearinghouse for datasets published by the City & County of San Francisco. The site allows to find datasets in several ways: general search, tags/keywords, categories, and rating. The goal is to improve access to city data through open machine-readable formats.
Anyway, there does not seem to be any SPARQL endpoint or any other semantic expression of the exposed datasets... Maybe in a future iteration?

A presentation which explains how semweb people should work to create more user-friendly tools. There is a common dream about the semantic web : it should help develop omnipotent applications. Instead of this, the author explain that developers should concentrate on creating useful software, using semweb technologies. Meaningful.

about:
dbrec is a new kind of recommender system, entirely based on Semantic Web and Linked Data technologies, providing recommendations for 39,000 artists from DBpedia (and consequently from Wikipedia) based on the relationships that they hold together, either directly (e.g. having played together) or indirectly (e.g. playing the same genre, sharing a common record label or even being associated in a particular cultural movement).
The W3C published 2 days ago the OWL2 Recommendation, made by 12 documents. A great step further in SW technologies, 5 years after the first OWL Recommendation !

Provided with free-form text, the service identifies places mentioned in text, disambiguates those places, and returns unique identifiers (WOEIDs) for each, as well as information about how many times the place was found in the text, and where in the text it was found. Gorgeous!
Zemanta is a text enrichment tool. Packaged as a firefox extension, it helps adding tags, photos, links to the texts you type in your web browser. It is based on "natural language processing, machine learning and fine tuning", and would take profit out of SemWeb technologies.
The problem with both keywords and tags is that they are just words. But what would happen if, instead of words, we used objects? What if we used unique concepts that would always and everywhere have the same name and would refer to the specific object?

Yahoo opens to the semantic web.
A few weeks ago, we began talking about the new Yahoo! Search open platform. Today, we're releasing more details about two important components of the initiative -- the developer platform as well as our support of a number of semantic web standards.
The Massachusetts Commonwealth Chief Technology Strategist Sarah Bourne posted a comment about problems that microformats present for website accessibility.
Now that the RDFa syntax document is in last call, and people like Yahoo! are starting to index the data, it's worth putting more of your own data into your web-pages, using RDFa. A simple place to start is to modify your home-page or blog profile so that it includes FOAF information.
"Semantic Web will start the long, slow decline of relational database technology", "If you have a firm grasp of the theoretical underpinnings of the semantic web, things like RDF, tuples, Sparql and OWL that make my brain hurt, you will be able to charge a fat premium in consulting fees for a while, as not many people really understand this stuff. But make hay while the sun shines, as some entrepreneur will surely figure out how to abstract this stuff and make it accessible for the masses."
This is a site for large data sets and the people who love them: the scrapers and crawlers who collect them, the academics and geeks who process them, the designers and artists who visualize them. It's a place where they can exchange tips and tricks, develop and share tools together, and begin to integrate their particular projects.
The Resource Description Framework RDF allows the users to describe Web documents and resources from the real world—people, organisations, things—in a computer-processable way. Publishing such descriptions on the Web creates the Semantic Web. URIs (Uniform Resource Identifiers) are very important, forming the link between RDF and the Web. This document presents guidelines for their effective use. It discusses two strategies, called 303 URIs and hash URIs. It gives pointers to several Web sites that use these solutions, and briefly discusses why several other proposals have problems.
The purpose of this post is to highlight 10 Semantic Apps. We're not touting this as a 'Top 10', because there is no way to rank these apps at this point - many are still non-public apps, e.g. in private beta. It reflects the nascent status of this sector, even though people like Hillis and Spivack have been working on their apps for years now.

Compared to these APIs, Linked Data has the advantage of providing a single, standardized access mechanism instead of relying on diverse interfaces and result formats.

Mais voilà que pour contrer cette épidémie pernicieuse, on vient d’associer le Web sémantique à la version 3.0 du Web. Voir article sur Wikipedia. Bonne idée? Pas sûr. Le simple fait de donner des numéros de version au terme Web implique une amélioration commerciale et non une évolution de la technologie. Les gens achètent les nouvelles versions… dans le cas du Web, ils doivent d’abord les faire! Si on veut être précis, il faudrait dire Web-2 v. 0.1a.
Du gigantesque catalogue qu'il est, le web pourrait se transformer pour apporter des réponses complètes à des requêtes en langage naturel, et favoriser l’émergence de nouvelles formes d'intelligence collective. Certains l'appellent le "web 3.0".

In this paper, we present our work aimed at improving retrieval and navigation services on bibliographic data. In this system, knowledge about the domain of documents (publications) is stored in an ontology, a formal model of conceptual knowledge. The ontology is employed to represent concepts and their relationships in order to carry out reasoning about documents. Reasoning helps researchers by providing more efficient document retrieval and navigation.

The XHTML Role Attribute defined in this specification allows the author to annotate XML Languages with machine-extractable semantic information about the purpose of an element.
Users and software agents should be able to discover, invoke, compose, and monitor Web resources offering particular services and having particular properties, and should be able to do so with a high degree of automation if desired. Powerful tools should be enabled by service descriptions, across the Web service lifecycle. OWL-S (formerly DAML-S) is an ontology of services that makes these functionalities possible. In this submission we describe the overall structure of the ontology and its three main parts: the service profile for advertising and discovering services; the process model, which gives a detailed description of a service's operation; and the grounding, which provides details on how to interoperate with a service, via messages.
This document defines an alternative means of serializing the results of the SPARQL ASK and SELECT query forms using JSON, a lightweight representation format which emphasizes concision and legibility. (one day my son, that will work...)
PingtheSemanticWeb.com is a web service archiving the location of recently created/updated FOAF, DOAP or SIOC RDF documents on the Web. If one of those documents is updated, its author can notify the service that the document have been updated by pinging it with the URL of the document. PingtheSemanticWeb.com is used by crawlers or other type of software agents to know when and where the latest updated FOAF, DOAP and SIOC documents can be found. So it requests a list of recently updated documents as a starting location to crawl the semantic web.

GeoRSS is a simple proposal for geo-enabling, or tagging, “really simple syndication” (RSS) feeds with location information. GeoRSS standardizes the way in which “where” is encoded with enough simplicity and descriptive power to satisfy most needs to describe the location of Web content. It is extensible and upwardly-compatible with more sophisticated formats like the OGC GML (Geography Markup Language®).
SIOC (Semantically Interlinked Online Communities) is an ontology for describing discussion forums and posts on topic threads in online community sites. This includes but is not limited to: blogs, bulletin boards, mailing lists, newsgroups, etc.

Pourtant, le WS est déjà riche de nombreux langages et outils qui peuvent trouver leur place au sein de l’entreprise, et améliorer la manière dont celle-ci traite, organise et publie ses données.
