Marbles Linked Data Engine VisiNav VisiNav is a system to search and navigate web data, collected from a multitude of sources. In summary, the system demonstrates how to combine data from multiple sources into a single unified view, how to search and navigate the aggregated dataset, and how to re-use query results from web data in external applications. On a conceptual level, VisiNav deals with objects. Some of the funcationality of VisiNav can nowadays be found in Google's KnowledgeGraph and Facebook's Graph Search. The dataset in the online system has been collected from the web (view top 99 sources - requires SVG-capable browser). Now, the system allows for searching objects teleporting between objects faceted browsing to incrementally restrict a result set set-based link navigation to navigate between object sets You can visualise query results in a table, graph, map, or timeline view. The following video demonstrates the capabilities of the system. Andreas Harth. Andreas Harth. Andreas Harth.
Resource Description Framework The Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications[1] originally designed as a metadata data model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax notations and data serialization formats. It is also used in knowledge management applications. RDF was adopted as a W3C recommendation in 1999. Overview[edit] RDF is an abstract model with several serialization formats (i.e. file formats), so the particular encoding for resources or triples varies from format to format. This mechanism for describing resources is a major component in the W3C's Semantic Web activity: an evolutionary stage of the World Wide Web in which automated software can store, exchange, and use machine-readable information distributed throughout the Web, in turn enabling users to deal with the information with greater efficiency and certainty.

The Wolfram Education Portal Is Here! January 18, 2012 — Wolfram Blog Team Teachers, are you looking for a new way to integrate technology into your classroom? How about through a dynamic textbook or pre-generated lesson plans? Students, are you looking for some extra help or practice in your classes? We are happy to announce the launch of the free Beta version of the Wolfram Education Portal. We developed the interactive textbook by working with the CK-12 Foundation, a non-profit organization with the mission to produce free and open source K-12 materials aligned to state curriculum standards and customized to meet student and teacher needs. In the future we hope to add many cool and exciting features for teachers and students to explore, including community features, problem generators, web-based course apps, and the ability to create your very own personalized content! The Wolfram Education Portal was built with the technology from Mathematica, and Wolfram|Alpha, and the Computable Document Format (CDF).
Planet RDF SamyGO, Samsung Firmware on the GO - Comodo IceDragon Generating RDF from data.gov - Data-gov Wiki From Data-gov Wiki Overview Many of the datasets in data.gov are available as tables (spreadsheets). This makes it easy to translate the datasets into RDF by generating a triple for each table cell where the row id is the subject, the column name is the predicate, and the cell content is the object. Our work adopted the following principles: In the first principle, we minimize our translation by (i) preserving the functional structure of the original tables and (ii) skipping additional understanding of the cell content. In the second principle, we keep the translated RDF friendly to Web users. Our third principle was approached by using a semantic wiki to host user contributed extensions. In our fourth principle we preserve knowledge provenance of the converted RDF documents by embedding metadata about their sources, creators, and creation date time using the well-known Dublin Core and FOAF vocabularies. The Problem Datasets at data.gov are organized in the following structure parse raw data

Semantic desktop In computer science, the Semantic Desktop is a collective term for ideas related to changing a computer's user interface and data handling capabilities so that data is more easily shared between different applications or tasks and so that data that once could not be automatically processed by a computer could be. It also encompasses some ideas about being able to automatically share information between different people. This concept is very much related to the Semantic Web but is distinct insofar as its main concern is the personal use of information. General description[edit] The vision of the semantic desktop can be considered as a response to the perceived problems of existing user interfaces. Secondly there is the problem of relating different files with each other. Related to this a user will often access a lot of data from the Internet which is segregated from the data stored locally on the computer, being accessed through a browser or other programs. Standardization effort[edit]
How to recover TrueCrypt encryption password | unprotect.info - Comodo IceDragon Before using the unprotect.info software, first you need to download it to your computer. After downloading the installation file, run it to install the unprotect.info software. After the installation is complete, the software is ready to use. To recover a password to an encrypted volume, run unprotect.info software (by double-clicking on its Desktop icon, or by choosing the unprotect.info command from Windows Start - All Programs menu. You should see the following window open: Press the Begin button and select the file that contains the encrypted volume for which you want to recover the password. You can use this window to select the character sets from which you want to try the passwords. Lowercase characters abcdefghijklmnopqrstuvwxyz Uppercase characters Digits Punctuation characters Other special characters After selecting the character sets, press the Start button to begin the password recovery.
Tracker Tracker is a search engine, search tool and metadata storage system. It allows you to find the proverbial needle in your computer's haystack as well as providing a one stop solution to the organisation, storage and categorisation of your data.

The service is free to try for a few days, after that you will be asked for payment which can be done with credit card, Paypal, wire transfer or Bitcoin. Credit card corporations force businesses to keep payment details stored for two weeks, Countermail claims to automatically destroy the records after that length of time but the credit card company and Paypal will likely preserve payment details for years although they will not be able to link them to any specific Countermail account or nick. If you pay with Bitcoin you will make tracing payment origin much more difficult but there is a surcharge. Signing up is simple, not requiring any personal information other than choosing a username and password, you only need Java installed in your computer, after account creation you can get rid of Java and use IMAP and SMTP with Thunderbird and Enigmail.
RelFinder - Visual Data Web Are you interested in how things are related with each other? The RelFinder helps to get an overview: It extracts and visualizes relationships between given objects in RDF data and makes these relationships interactively explorable. Highlighting and filtering features support visual analysis both on a global and detailed level. The RelFinder is based on the open source framework Adobe Flex, easy-to-use and works with any RDF dataset that provides standardized SPARQL access. Check out the following links for some examples: The RelFinder can easily be configured to work with different RDF datasets. The RelFinder can also be more deeply integrated with your project: Integrating the RelFinder See the following examples of how the RelFinder is integrated into other projects: Ontotext applies the RelFinder to enable an exploration of relationships in the biomedical domain. All tools on this website are research prototypes that might contain errors.
