  1. Semantic Search Engines for Health Information HIP Semantics, October 2010 The Barking Dog TamasDoszkocs, Ph.D.Computer Scientisttamasd@gmail.com

  2. “What is semantic search?”or WhatisThe Meaning of Meaning? “He who knows does not speak, he who speaks does not know” Lao Tse "It depends on what the meaning of the word 'is' is” Bill Clinton “the answer, my friend, is blowing in the wind” Bob Dylan

  3. What is semantic search? “semantic search is a searchora questionoran actionthat producesmeaningful results, even whenthe retrieved items containnone of the query terms, or the search involvesno query text at all” (my definition)

  4. Thinking of the Web andSemantic Search “Wholly new forms of encyclopedias will appear, ready made with a mesh of associative trails running through them, ready to be dropped into the MEMEX and there amplified” Vannevar Bush“As We May Think”Atlantic Magazine JULY 1945

  5. Trends in Searching 2010 • The Web is the Memex – zettabytes 10^21 bytes Vertical Search Universal Search Social Search Real Time search: Google Instant Mobile Search:Context Aware Computing Semantic Web Semantic Search Connected Mobility • Focus on Consumers • Information Democracy • Social content • Social search Social interaction Information Monopolies manipulating text, context, peoplemeaning,

  6. Semantic Searching: Web 2.5 Understanding content Understanding context Understanding people Semantic Search vs. The Semantic Web Meaningful results Web 1.0 linking pages Web 2.0 linking content and people Web 2.5 Semantic Search Web 3.0 Semantic Weblinking data and people and applications Web 4.0¿inferences, conjectures, the pursuit of happiness ?

  7. Semantic Searching: a long history • Libraries as Knowledge Bases • Librarians as Search Engines • Doctors as Knowledge Bases • Patients as Search Engines • The Web as the Knowledge Base • Search Engines as Librarians

  8. Specialized Semantic Search Engines • • domain knowledge • matching people and needs • improving diverse applications • real time trends • finding jobs • recommendations for movies, music, goods, etc. • health • semantic Facebook • Semantic resources and tools • Related searches/topics • Related items • Semantic/linguistic annotations • Semantic Clustering (DOE/OSTI) • Faceted Search - Triangle Research Libraries • Computable Knowledge • Semantic analysis • Semantic synthesis

  9. Semantic Search Engines for Health Rich Semantic Resources in Biomedicine Small Number of Important Facets Diseases and conditions Causes Tests and diagnosis Treatments and procedures Drugs and substances Life style and prevention Alternativemedicine ParticipatoryMedicine E-patients First, second and third opinions on and off the Web Health Professionals Friends Family InformedPersonal Health Decisions

  10. Trusted Health Informationis vital for dealing with health problems, promoting healthy behavior, making healthy decisions and for overall well being However, as Mark Twain put it: Be careful of reading health books.You may die of a misprint!

  11. examples of health search engines with Semantic Search Capabilities HealthLine uses own taxonomy of > 250,000 health terms thousands of Indian doctors and pharmacists http://www.everydayhealth.com/ Meta-data clusters Topical clusters Second most popular site after WebMD http://righthealth.com/ federated search engine taxonomy of several million nodes organized into a graph by using a combination of human operators and algorithms http://MedStory.com high-level categorizations or popular URLs Purchased by Microsoft http://health.msn.com

  12. examples of health search engines with Semantic Search Capabilities http://www.semanticmedline.com/Semantic NLP "understands" word and phrase meanings within context http://skr3.nlm.nih.gov/SemMedDemo/ Research prototype Natural language processing is used to analyze salient content http://healthbase.netbase.com/ Based on language understanding Surfaces facts, events, behaviors and connections among them” combines classical keyword-based Web search with text-mining and ontologies http://www.nextbio.com/ „correlation engine” pre-computes billions of significant data connections http://healthmash.com/ Best-of-class semantic search engine Powered by an automatically generatedHealth Knowledge Base

  13. HealthMash Demo

  14. The Explore and Discover data comes from the Health Knowledge Base • The Health Knowledge Base is automatically generated from trusted health content sites and diverse knowledge sources, such asMeSHand UMLS.HealthMash also utilizes the Web itself as adatabase. • The Health Knowledge Base contains explicit knowledge about • Health Concerns • Causes • Signs and Symptom • Tests, Procedures, Treatments • Drugs and Substances andadverseeffects • Alternative, Complementary and Integrative Medicine • The Health Knowledge Base is available via a web service • The Health Knowledge Base facilitates exploration and discovery

  15. HealthMash utilizes the following NLP resources(these tools can also be licensed) • PolyDictionary (English, medical and scientific dictionary) • PolySpell(English, medical and scientific spell checkers) • PolyTagger (part-of-speech tagger) • PolyPhraser (phrase parser) • PolySearch(intelligent concept search engine for UMLS and other ontologies) • PolyCluster(search result clustering engine) • PolyMeta (federated search and discovery engine)

  16. HealthMash combines verticalsemantic search of Trusted Health Information, mashups(Health News, Videos etc),Semantic Relations in context for Exploration and Discovery and Table of Contents and Topic Clusters for drill down in search results and dynamic query modification

  17. Integrate the Health Knowledge Basevia aweb serviceinto yoursearch or federated search application
