    Real-Time Faceted Search is a journey; a journey that enables you to easily tell the internet what you're looking for and let the internet find it for you. It starts with the same key word everyone is familiar with, but then guides the user through a series of contextual prompts, or 'facets', that eventually build out a more 'complex query' more powerful than that of typical keyword search. Through the use of a number of GUI techniques, the user is able to either select or fill in elements of this query in intuitive ways with all the code crunching being hidden in the background. The query can then be run over mashed up linked data sources. This enables the everyday user to build out these deep queries over linked data and receive much more relevant results.

Semantic Search: The Myth and Reality - ReadWriteWeb - 0 views

  • Any technology that stands a chance to dethrone Google is of great interest to all of us, particularly one that takes advantage of long-awaited and much-hyped semantic technologies. But no matter how much progress has been made, most of us are still underwhelmed by the results. In head-to-head comparisons with Google, the results have not come out much different.
  • We all know that semantic technologies are powerful, but how and why?
  • The mistake is that semantic search engines present us with Google-like search box and allow us to enter free form queries. So we type the things that we are used to asking - primitive queries.
  • ...11 more annotations...
  • The situation is made more difficult by the fact that right now there is only a thin range of problems where semantic search can clearly do better. This range is complex queries involving inferencing and reasoning over a complex data set.
  • Sadly, natural language processing gives little advantage when it comes to this category of problems.
  • Before looking at the problems that are perfect for semantic search, lets look at the hardest problems. These are computationally challenging problems that really have nothing to do with understanding semantics.
  • There are fundamental limits to what we can compute, and a class of problems that have an exponential number of possible solutions is not going to be magically solved because we represent data as RDF.
  • The good news is that there is a set of problems that are great for semantic search. These are the problems we have been solving so wonderfully with relational database.
  • At its most structured extreme we find Freebase - the semantic database of everything. Freebase is accessible via free text search, but more importantly via MQL (Metaweb Query Language).
  • Companies like Hakia and Powerset are probably working the hardest. These companies are trying to simultaneously build Freebase-like structures on the fly and then do natural language queries on top of them. The difference is that Hakia is using (likely similar) technology to query over the entire web, while Powerset has (probably shrewdly) chosen to restrict the search to Wikipedia.
  • Here is the problem - the natural language interface has nothing to do with the underlying data representation.
  • Fundamentally, Hakia, Powerset, and Freebase are databases. Fundamentally, all of them have some kind of Natural Language Processing that translates the question into a canonical query over the database.
  • Having a simplistic search interface hurts Powerset and Hakia, and to a lesser extent Freebase, which is not positioning itself as generic search.
  • Instead, the expectation should really be to solve the problems that can not be solved by Google today.

    A KBucket page is a place to organize and publish your research.  The practice is known as content curation.  You can curate for yourself and people like you, or you can curate to promote your ideas and knowledge.  KBucket lets you manage the context of your information, which means the grouping, the tags and the meta tags.  All KBucket pages are hosted on the KBucket search platform.

Semantic Word Cloud Visualization - 1 views

  •  
    Semantics-preserving word cloud visulization tool. A word cloud consists of the most important words in that document. Each word is printed in a given font and scaled by a factor roughly proportional to its importance. The printed words are arranged without overlap and tightly packed into rectangular shape. Your word clouds can be tweaked with various fonts, layouts, and color schemes. Read the description for more details.

Google Knowledge Graph Search Engine (no API skills required) - 0 views

  •  
    "Introduction to the Knowledge Graph API The Google Knowledge Graph API reveals entity information related to a keyword, that Google knows about. This information can be very useful for SEO - discovering related topics and what Google believes is relevant. It can also help when trying to claim/win a Knowledge Graph box on search results. The API requires a high level of technical understanding, so this tool creates a simple public interface, with the ability to export data into spreadsheets."

    TranscriptomeBrowser host a large database of transcriptional signatures (TS, n~40 000)  extracted from Gene Expression Omnibus (~4 000 experiments) using the DBF-MCL algorithm.  TBrowser comes with a sophisticated search engine so that users can search for the biological contexts in which several genes were concomitantly regulated. Several examples are provided below and in the article published in PLoSONE . A video tutorial is
