Semantic Cloud is the API that powers semantic search engine SenseBot and contextual linking tool for bloggers LinkSensor. The API supports SOAP and REST protocols (HTTP GET). The idea is to empower semantic startups or any ventures that are looking to utilize an affordable high-quality semantic solution to build their applications. Semantic API features include: * extraction of semantic concepts from a page or document; * creating a "semantic cloud" of concepts describing a group of documents; * generating a multi-document summary of a set of pages; * generating an essay on a topic based on a set of documents. Multiple parameters allow the client to control the type and format of results.

With the AJAX Language API, you can translate and detect the language of blocks of text within a webpage using only Javascript. In addition, you can enable transliteration on any textfield or textarea in your web page. For example, if you were transliterating to Hindi, this API will allow users to phonetically spell out Hindi words using English and have them appear in the Hindi script.

s Richard MacManus recently predicted, in 2008 we'll witness the rise of semantic web services. From the native support for Microformats in Firefox 3, to the New York Times' utilization of rich headers metadata, to this week's release of the Social Graph API by Google, semantics are starting to slip onto the web. The impact is being felt because large companies are really starting to focus on structured information. In the same vein, last week Reuters - an international business and financial news giant - launched an API called Open Calais. The API does a semantic markup on unstructured HTML documents - recognizing people, places, companies, and events. This technology is the next generation of the Clear Forest offering, which Reuters acquired last year. We have profiled Clear Forest on ReadWriteWeb and in this post we will look at what Reuters opened up and why.

In order to keep data structures in Semantic CrunchBase close to the source API, I used a 1-to-1 mapping between CrunchBase JSON keys and RDF terms (with only a few exceptions). This was helpful for people knowing the JSON API, but it wasn't easy to interlink the converted information with existing SemWeb data such as FOAF, or the various LOD sources.

I have written a wrapper to expose openlibrary.org api data as RDF. It is written in Python and deployed on Google App Engine. It is only an illustration of Linked Data publication, and in order to get a first feedback, so do not rely on it in your application since the URL or the content will change in the future.

Jersey is the open source (under dual CDDL+GPL license) JAX-RS (JSR 311) Reference Implementation for building RESTful Web services. But, it is also more than the Reference Implementation. Jersey provides additional APIs and extension points (SPIs) so that developers may extend Jersey to suite their needs.

NG4J - 'Named Graphs API for Jena' is an extension to the Jena Semantic Web framework for parsing, manipulating and serializing sets of Named Graphs. For details about Named Graphs see http://www.w3.org/2004/03/trix/

JAX-RS: Java API for RESTful Web Services

Relevant content from around the web brought to you as you're typing. API allows to bring these related Images, Articles, Hyperlinks and Tags to your Application.

The Yahoo! BOSS API allows you to access the Yahoo! search index with new levels of freedom. You can rearrange the results, change their look, have unlimited requests, mash the results with other resources, and you don't even have to let people know that Yahoo! is powering the page. Many people are busy mashing the BOSS results with internal data sets, proprietary logic, and new visual interfaces.

The Open Library is a project of the Internet Archive. Its goal is to create an online catalog that contains one web page for every book ever published. To do this, it accepts data from a variety of sources: libraries, publishers, book-sellers, and individuals.

Apache CouchDB is a distributed, fault-tolerant and schema-free document-oriented database accessible via a RESTful HTTP/JSON API. Among other features, it provides robust, incremental replication with bi-directional conflict detection and resolution, and is queryable and indexable using a table-oriented view engine with JavaScript acting as the default view definition language.

OpenSocial's API reference describes a number of classes ('Person', 'Name', 'Email', 'Phone', 'Url', 'Organization', 'Address', 'Message', 'Activity', 'MediaItem', 'Activity', …), each of which has various properties whose values are either strings, references to instances of other classes, or enumerations. I'd like to make them usable beyond the confines of OpenSocial, so I'm making an RDF/OWL version. OpenSocial's schema is an attempt to provide an overarching model for much of present-day mainstream 'social networking' functionality, including dating, jobs etc. Such a broad effort is inevitably somewhat open-ended, and so may benefit from being linked to data from other complementary sources.

Open, distributed, social. * About The DiSo Project * Blog * Links * Chat About The DiSo Project Silo free living. Social networks are becoming more open, more interconnected, and more distributed. Many of us in the web creation world are embracing and promoting web standards - both client-side and server-side. Microformats, standard apis, and open-source software are key building blocks of these technologies. This model can be described as having three sides/legs/arms/spokes - pick your connection: Information, Identity, and Interaction. DiSo (dee * zoh) is an umbrella project for a group of open source implementations of these distributed social networking concepts. or as Chris puts it: "to build a social network with its skin inside out".

MnM is an annotation tool which provides both automated and semi-automated support for annotating web pages with semantic contents. MnM integrates a web browser with an ontology editor and provides open APIs to link to ontology servers and for integrating information extraction tools.

Want to create your own semantic search engine, but just don't have the PhDs? Semantic search engine Hakia is opening up APIs to let anyone build their own semantic search application on top of its technology. Hakia looks at the meaning of Web pages and matches search queries using its own quality index of trusted, relevant sites.

Creating a weblog in 15 minutes with Rails 2 In 15 minutes, we go from scratch to complete weblog engine with comments, ajax, an ATOM feed, an XML and JSON API, tests, an administrative interface, and much more! We strongly advise that you sit down before starting this whirlwind tour. Your head may well be spinning at the end.

A system and method for organizing knowledge in such a way that humans can find knowledge, learn from it, and add to it as needed is disclosed. The exemplary system has four components: a knowledge base, a learning model and an associated tutor, a set of user tools, and a backend system. The invention also preferably comprises a set of application programming interfaces (APIs) that allow these components to work together, so that other people can create their own versions of each of the components. In the knowledge web a community of people with knowledge to share put knowledge in the database using the user tools. The knowledge may be in the form of documents or other media, or it may be a descriptor of a book or other physical source. Each piece of knowledge is associated with various types of meta-knowledge about what the knowledge is for, what form it is in, and so on. The information in the knowledge base can be created specifically for the knowledge base, but it can also consist of information converted from other sources, such as scientific documents, books, journals, Web pages, film, video, audio files, and course notes. The initial content of the knowledge web comprises existing curriculum materials, books and journals, and those explanatory pages that are already on the World Wide Web. These existing materials already contain most of the information, examples, problems, illustrations, even lesson plans, that the knowledge web needs. The knowledge base thus represents the core content (online documents or references to online or offline documents); the meta-knowledge that was created at the time of entry; and a number of user annotations and document metadata that accumulate over time about the usefulness of the knowledge, additional user opinions, certifications of its veracity and usefulness, commentary, and connections between various units of knowledge.

Protocol buffers are a flexible, efficient, automated mechanism for serializing structured data - think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages. You can even update your data structure without breaking deployed programs that are compiled against the "old" format.
