sensemaking

Here's an important question for all of us: How do you make sense of something that's big and complicated? Say… something like why your users aren't passionate about your product?

The contention made in this article is that ontologies are pivotal to several seemingly disparate technical endeavours that are currently emergent and have had more or less publicity. These include Event Driven Architecture (EDA), Complex Event Processing (CEP), Service Oriented Architecture (SOA), Master Data Management (MDM), which are supported by specific ontological initiatives most notably the Semantic Web, which is further leveraged by Model Driven Architecture (MDA). Furthermore how these efforts are all dependent on the adherence to common standards. These endeavours, and their complementary interrelationships, and specifically their relationship to ontology, are explored in more detail below.

By integrating heterogeneous original data with uniform RDF format, creating additional ontology mappings between GO terms, and introducing a set of reasoning rulebases, we proposed a RDF model GORouter.

Invariant study is fundamental to any scientific research, especially when the research domain is as complex as World Wide Web. Invariants are supposed to be constant within the specified research scope. By well understanding the invariants we may effectively improve the knowledge over many complicated issues. Therefore, it is unsurprisingly for us to see the discussion of invariant study in the new Web Science Research Initiative.

This text sets out a series of approaches to the analysis and synthesis of the World Wide Web, and other web-like information structures. A comprehensive set of research questions is outlined, together with a sub-disciplinary breakdown, emphasising the multi-faceted nature of the Web, and the multi-disciplinary nature of its study and development. These questions and approaches together set out an agenda for Web Science, the science of decentralised information systems. Web Science is required both as a way to understand the Web, and as a way to focus its development on key communicational and representational requirements. The text surveys central engineering issues, such as the development of the Semantic Web, Web services and P2P. Analytic approaches to discover the Web's topology, or its graph-like structures, are examined. Finally, the Web as a technology is essentially socially embedded; therefore various issues and requirements for Web use and governance are also reviewed.

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.

Triplify provides a building block for the semantification of Web applications. Triplify is a small plugin for Web applications, which converts database content into RDF or JSON feeds and provides a Linked Data interface.

This blog is about the OntoGame series of games: games with a purpose for the Semantic Web.

ECOSPACE pursues the vision that by 2012 every Professional in Europe is empowered for seamless, dynamic and creative collaboration across teams, organisations and communities through a personalised collaborative working environment. ECOSPACE contributes to this vision through 4 main objectives: * The definition of innovative work paradigms through the analysis of eProfessionals and their related organisation. * The design and development of an open standards, service-oriented architecture for complementary and alike systems. * A collaboration middleware and services to enable seamless and instant collaboration among knowledge workers in group forming networks, beyond organisational boundaries. * The creation of new tools that simplify the complexity of collaboration in dynamic work environments and which enable users for creative and knowledge intensive tasks.

The OBO Foundry is a collaborative experiment involving developers of science-based ontologies who are establishing a set of principles for ontology development with the goal of creating a suite of orthogonal interoperable reference ontologies in the biomedical domain. The groups developing ontologies who have expressed an interest in this goal are listed below, followed by other relevant efforts in this domain.

Vannevar Bush's 1945 article, "As We May Think," has been much celebrated as a central inspiration for the development of hypertext and the World Wide Web. Less attention, however, has been paid to Bush's motivation for imagining a new generation of information technologies; it was his hope that more powerful tools, by automating the routine aspects of information processing, would leave researchers and other professionals more time for creative thought. But now, more than sixty years later, it seems clear that the opposite has happened, that the use of the new technologies has contributed to an accelerated mode of working and living that leaves us less to think, not more. In this talk I will explore how this state of affairs has come about and what we can do about it.

Here, we present a computational model that learns structures of many different forms and that discovers which form is best for a given dataset. The model makes probabilistic inferences over a space of graph grammars representing trees, linear orders, multidimensional spaces, rings, dominance hierarchies, cliques, and other forms and successfully discovers the underlying structure of a variety of physical, biological, and social domains. Our approach brings structure learning methods closer to human abilities and may lead to a deeper computational understanding of cognitive development.

Open Context features an innovative folksonomy system that will encourage individual users to add value to the information in Open Context. This powerful social software allows users to add meaningful tags (keywords) to data they discover in their searches.

Mutual respect, trust, and recognition that cultural differences exist, matter, and must be explicitly dealt with are requirements of successful international projects. In summary, I would suggest these principles for the success of international collaboration: * Two (or more) teams share the same goal and seek the overall optimal result, not the local optimum. * Each team should clearly recognize and value the other party's different culture and traditions. * The single most important word in international projects is trust. Team members earn trust by being sincere, honest, and open-minded.

A small, digital book startup thinks it has a solution to the age-old student lament: overpriced textbooks that have little value when the course is over. The answer? Make them open source -- and give them away.

Andreas Hotho's talk more specifically addressed the search for methods to identify tags which describe the same concept (or a more specific / a more general concept respectively) within a folksonomy. He suggested two approaches: 1. Applying measures directly to folksonomy statistics, allowing to describe tags as a vector; e.g. co-occurrence frequency and FolkRank could serve as a similarity measure (with these two having a tendency towards high-frequency tags) or a cosine method (which is more likely to produce "siblings") 2. Looking up tags in an external thesaurus/vocabulary (for instance achieving semantic grounding by mapping a tag and its most similar tags with Wordnet Synsets)

When it comes to product searches, Yotify is very smart. It doesn't just look at keywords, but also lets you know what the current best price is and then lets you select a checkbox to have the service alert you if the price drops below a certain point. You can also optionally check to be alerted when there are new product reviews available. The shopping section features scouts for common searches like digital cameras and laptops, but the shortcuts section lets you create more specific searches for a keyword, like a product ID or model number.

The aims of clinical and translational research are to achieve a better understanding of the pathogenesis of human disease in order to develop effective diagnostic, therapeutic and prevention strategies. Biomedical informatics can play an important role in supporting this research by facilitating the management, integration, analysis and exchange of data derived from and related to the research problems being studied. A key aspect of this support is to bring clarity, rigor and formalism to the representation of 1. disease initiation, progression, pathogenesis, signs, symptoms, assessments, clinical and laboratory findings, disease diagnosis, treatment, treatment response and outcome, and 2. the interrelations between these distinct entities both in patient management and in clinical research, thus allowing the data to be more readily retrievable and shareable, and more able to serve in the support of algorithmic reasoning.
