<p>Natasha Lloyd unveiled an application she has built using OpenAmplify. According to Natasha, "Overall, I am impressed with OpenAmplify for two reasons. One, it provides a valuable service for free, and two, it uses a community model. Rather than building applications themselves, the OpenAmplify team provides the tools for other people to do it."</p>...

ThManager is an Open Source Tool for creating and visualizing SKOS RDF vocabularies, a W3C initiative for the representation of knowledge organization systems such as thesauri, classification schemes, subject heading lists, taxonomies, and other types of controlled vocabulary. ThManager facilitates the management of thesauri and other types of controlled vocabularies, such as taxonomies or classification schemes. The tool has been implemented in Java and has the following features:
Multi-platform (Windows, Unix). As it has been developed in Java and the storage of metadata records is managed directly through the file system, the application can be deployed in any platform with the minimum requirement of having installed a Java virtual machine.
Multilingual. The application has been developed following the Java internationalization methodology. Nowadays, there are Spanish and English versions. With little effort, other languages could be supported.
Selection and filtering of the thesauri stored in the local repository.
Description of thesauri by means of metadata in compliance with a Dublin Core based application profile for thesaurus (See application profile) . These metadata can be either visualized in HTML or edited through a form.
Visualization of thesaurus concepts. The visualization interface includes the following widgets:
Alphabetic viewer: It provides the list of thesaurus concepts alphabetically ordered in the selected language.
Hierarchical viewer: It provides a tree showing the hierarchical structure of thesaurus concepts.
Concept viewer: For a selected concept it shows all the properties allowing additionally the navigation to the related concepts by means of hyperlinks.
Search tool: It facilitates search of concepts. The searching process is based on preferred labels allowing the following criteria: "equals", "starts with" and "contains".
Edition of thesaurus content. The tool provides an edition interface to modify the content of a thesaurus: creation of concepts, deletion of concepts, and update of concept properties.
Exchange of thesauri according to SKOS format. The export operation includes the export of thesaurus metadata.
Extraction of related concepts in WordNet. It generates an automatic mapping of thesaurus concepts against the concepts of Wordnet lexical database.
On-line help by means of PDF visualization.
Data.gov launched in May this year to make huge data sets of information from federal agencies available in machine-readable formats. While incredibly valuable, these data sets are not particularly useful in their current format to anyone but researchers, statisticians, sociologists, developers, or others used to parsing databases searching for trends.
The Similarity Library aims at providing developers with a library for assessing similarity both between words and sentences. This library in an extension of the JWSL (Java WordNet Similarity Library). In the current implementation, there are two categories of similarity measures between words: measures exploiting ontologies such as WordNet, MeSH or the Gene Ontology measures…

A gentle introduction to the Semantic Web by Sean B. Palmer, 2001

The Semantic Network consists of (1) a set of broad subject categories, or Semantic Types, that provide a consistent categorization of all concepts represented in the UMLS Metathesaurus®, and (2) a set of useful and important relationships, or Semantic R
The Web is designed to support flexible exploration of information by human users and by automated agents. For such exploration to be productive, information published by many different sources and for a variety of purposes must be comprehensible to a wide range of Web client software, and to users of that software.
HTTP and other Web technologies can be used to deploy resource representations that are self-describing: information about the encodings used for each representation is provided explicitly within the representation. Starting with a URI, there is a standard algorithm that a user agent can apply to retrieve and interpret such representations. Furthermore, representations can be what we refer to as grounded in the Web, by ensuring that specifications required to interpret them are determined unambiguously based on the URI, and that explicit references connect the pertinent specifications to each other. Web-grounding ensures that the specifications needed to interpret information on the Web can be identified unambiguously. When such self-describing, Web-grounded resources are linked together, the Web as a whole can support reliable, ad hoc discovery of information.
This finding describes how document formats, markup conventions, attribute values, and other data formats can be designed to facilitate the deployment of self-describing, Web-grounded Web content.
This paper presents the results of a case study of a (perceived) problem of information overload from e-mail in a large firm. We argue that for CMCs to be effective there is a need to establish a ‘context’ in which the message can be interpreted.
