  • Latent Semantic Indexing Now Even More Crucial for Site Ranking

    19. December 2012, added by Tassilo Pellegrini, Category: Market Scan

    SBWIRE: saka, Japan -- (SBWIRE) -- 12/19/2012 -- In the past, the way websites were ranked was widely dependent on the placement of keywords in the site pages. However, according to Ace Site Creator, a website that provides people with in-depth information about online marketing, the recent Google Penguin update has led to a significant change in this process. As a spokesperson from Ace Site Creator explained, in regards to on-page optimization, including certain keywords is no longer as important as it once was. In many cases, the top results for online searches will turn up sites that do not even have the exact keyword or phrase in the results. Instead, the emphasis will be on the overall quality of the article. This means that something called latent semantic indexing, or LSI, is now extremely important for site owners to learn about and utilize. “LSI is a better gauge of how thoroughly the topic is covered in the article,” he said.

  • Applying semantic web technologies for phenome-wide scan using an electronic health record linked Biobank

    17. December 2012, added by Tassilo Pellegrini, Category: Market Scan

    7th SPACE: The ability to conduct genome-wide association studies (GWAS) has enabled new exploration of how genetic variations contribute to health and disease etiology. However, historically GWAS have been limited by inadequate sample size due to associated costs for genotyping and phenotyping of study subjects. This has prompted several academic medical centers to form "biobanks"where biospecimens linked to personal health information, typically in electronic health records (EHRs), are collected and stored on a large number of subjects. This provides tremendous opportunities to discover novel genotype-phenotype associations and foster hypotheses generation. Results: In this work, we study how emerging Semantic Web technologies can be applied in conjunction with clinical and genotype data stored at the Mayo Clinic Biobank to mine the phenotype data for genetic associations.

  • COEUS: "semantic web in a box"for biomedical applications

    17. December 2012, added by Tassilo Pellegrini, Category: Market Scan

    7th SPACE: As the "omics"revolution unfolds, the growth in data quantity and diversity is bringing about the need for pioneering bioinformatics software, capable of significantly improving the research workflow. To cope with these computer science demands, biomedical software engineers are adopting emerging semantic web technologies that better suit the life sciences domain. The latter's complex relationships are easily mapped into semantic web graphs, enabling a superior understanding of collected knowledge. Despite increased awareness of semantic web technologies in bioinformatics, their use is still limited. Results: COEUS is a new semantic web framework, aiming at a streamlined application development cycle and following a "semantic web in a box"approach.

  • Reactions on Twitter to the Pope's First Tweet as Seen through Semantic Technology

    13. December 2012, added by Tassilo Pellegrini, Category: Market Scan

    MARKET WIRE: The themes of poverty, children and homosexuality are unseated by the topics of Jesus, faith and prayer after the Pope's first official tweet MODENA, ITALY--(Marketwire - Dec. 13, 2012) - Expert System, the semantic technology company, conducted a semantic analysis to understand the reaction of Twitter users after the activation of @pontifex, and the response to the first tweets by Pope Benedict XVI on December 12. Using the Cogito semantic software, Expert System analyzed a sample of more than 20,000 tweets to the Pope's Twitter accounts and hashtags related to #askpontifex. The tweets were classified in the predominant categories of religion; art, culture and entertainment; economy and finance; and crime. Among the most relevant topics were people (Pope, Jesus and God), places (Vatican, Africa, Rome and Italy), verbs (do, can, tell, know, must, pay) and nouns (church, gold, question, child, Christmas, truth and Sunday).

  • Semantic Databases: Destiny Or Distraction?

    5. December 2012, added by Tassilo Pellegrini, Category: Market Scan

    INFORMATION WEEK: Here's how to decide where flexible semantic technologies can replace more rigid relational systems. Don't buy into the idea that semantic database technologies are just for consumer-facing services such as BBC Online or the semantic Web initiatives embraced by the likes of Best Buy and Cisco. In much the same way that consumerization drives innovation in end user computing, semantic database technologies deliver benefits that businesses of all stripes should be exploiting. AdTech Ad At a high level, semantic databases offer five main benefits: They work with your existing relational databases. They align with Web technologies. Their underlying technology speeds integration of multiple databases. They're based on data structures that are flexible by design. And thus they can help enterprises tackle big data challenges.

  • Leveraging Private Cloud Technologies to Improve Prior Investments in Semantic Technologies and Data Warehouses

    5. December 2012, added by Tassilo Pellegrini, Category: Market Scan

    BIOIT WORLD: Pharmaceutical R&D divisions normally possess a significant amount of warehoused legacy data that bears directly on other areas of the enterprise, such as new product development, manufacturing pipelines, clinical studies, regulatory affairs, etc., where a better understanding and reuse of data can be beneficial from a cost and productivity standpoint.  In large enterprises, it can be difficult for scientists, engineers, management and other stakeholders to quickly and effectively access pertinent data that allow for improved business decisions.  Getting that data out of legacy  systems can be difficult, which is one of the reasons that semantic technologies have been sought after for some years in the pharmaceutical and bio-tech areas.  The Value of Semantics

  • Semantic MediaWiki 1.8 released

    4. December 2012, added by Tassilo Pellegrini, Category: Market Scan

    THE H OPEN: The new version 1.8 of Semantic MediaWiki (SMW) has upgraded its backend module for storing data. Storing and reading data should now be faster due to improved caching mechanisms and optimised table layouts. Semantic MediaWiki is an extension for the MediaWiki software, which is used by projects such as Wikipedia and which allows users to store and query data in wiki pages as a semantic wiki. Regular Wikis are made of pages of structured text and untyped hyperlinks, but have little information about the data within the page, while a semantic wiki is able to store annotations that capture information about the data making it possible to query the wiki like a database. For example, this can allow specially marked information on a page to be included in overview tables or integrated into other wiki pages without redundantly duplicating the data. RDF export tools also provide interfaces to the semantic web.

  • Place Your Bets, People: Semantic Speech Recognition and the Future of Libraries | Peer to Peer Review

    29. November 2012, added by Tassilo Pellegrini, Category: Market Scan

    LIBRARY JOURNAL: Some years ago, when cellphones were still mostly the province of celebrities and hardcore business travelers, I was walking through an airport and saw a well-groomed and prosperous-looking man engaged in animated conversation with, as far as I could tell, himself. He certainly didn’t seem to be conversing with anyone nearby, anyway. As I (carefully) got closer and continued to watch him talking and gesticulating into the empty social space around him I thought to myself, “That’s interesting; he doesn’t look crazy…” But then as I passed him, I noticed that there was something stuck in his ear, and I realized he was using one of those newfangled Bluetooth devices that I had started hearing about.
