  • Let me start by offering my appreciation for our Chancellor Dr. Fingerhut’s visionary leadership in establishing the Ohio Center of Excellence program that identifies Centers and program that generate world-class research and help draw talent and investment to the state. I would be remiss if I did not call out tremendous leadership that our President Dr. Hopkins and his entire leadership team has shown in regards to identifying and promoting these centers– my tanks to Dr. Angle, Dr. Bantle. Dr. Jang, and Dr. Sudkamp– thanks for your early and steadfast support for Kno.e.sis.
  • Let me give a technological introduction to what our center is about: we all face a fire hose of data-- Pubmed adds 2000 to 4000 citations per day, it is usual to add about 5 gig from a single run of a scientific experiment -- and just imagine how much data created by all the cameras and 40 billion mobile sensors in the world! But even with all the search and browsing tools we have, we face huge information glut. How do we make sense from the data? Just as humans apply their knowledge and experience to understand what they see– we apply domain model or knowledge to attach meaningful labels to these data. Then we can apply computational techniques to visualize, provide situational awareness, discovery nuggets of knowledge of information and insight. For example, from all that biomedical data, what a scientist may be looking for is– how can we treat Migraine? What has Magnesium to do with Migraine? Why does Magnesium deficiency cause Migraine? What is the process by which Magnesium affects Migraine?
  • So what is Kno.e.sis about– it is about stepping away from the concerns of storing and searching data, to that of improving human experience, human effectiveness, human performance, human productivity.
  • Our 15 faculty from 4 colleges are already engaged in multiple jointly funded grants, pending proposals, serving on interdisciplinary programs like Biomedical Sciences PhD program and on committees of students of colleagues.
  • This work has been developed in collaboration with my peers at Kno.e.sis, Pablo N. Mendes and Dr. Cartic Ramakrishnan who is at ISI-University Southern California. Our Advisor is IEEE Fellow, Professor Amit Sheth.

  • The last representative work we’d like to share with you is our work on making sense of social data, like those from Twitter and facebookaround news worthy events that are of interest to a populace.The goal is to offer an understanding of what people are talking about and paying attention to
  • What the social perceptions behind the data might be, the multiple narratives
  • Twitris is our effort in this direction to help users keep up with observations made around news-worthy events.. Before I hand over the microphone to Dr. Mike Raymer, I’d like to leave you with a short demo of the deployed web application.

Demonstrate use of background knowledge  Named Entities, Relationships 3. Prototype Implementation  Semantic annotations for navigation 4. Aggregation Utilities  Saving, bookmarking, publishing etc 50
    51. 51. WHY SCOONER?  Query Reformulations  Impatient users  Recognition over Recall  Constrained navigation  Hyperlink dependent - apriori Fuzzy User Interests  Haiti Earthquake – Recovery, Relief, Political Climate, Crime Current approaches are not as effective for Exploratory Search (Search-and-Sift) Amit P. Sheth, Cartic Ramakrishnan: Relationship Web: Blazing Semantic Trails between Web Resources. IEEE Internet Computing 11(4): 77-81 (2007)
    52. 52. MOTIVATION  Users are information seekers Information is embedded in documents  A priori hyperlink dependent  Semantic Web Standards  Entity Identification (Semantic Annotations)  Relationshipand Triple Identification  Explore documents/information via relationships 52

    56. 56. SUMMARY  Novel Information Exploration Paradigm  Semantic Browser support Contextual Navigation  Identify Named Entities and Relationships  Provide Semantic Annotations  Utilities for Aggregation  Semantic Trails to Knowledge Discovery See demonstration at: http://knoesis.org/library/demos 56

    58. 58. Semantic Sensor Web Sensors are now ubiquitous, and constantly generating observations about our world
    59. 59. Semantic Sensor Web However, these systems are often stovepiped, with strong tie between sensor network and application
    60. 60. Semantic Sensor Web We want to set this data free
    61. 61. Semantic Sensor Web With freedom comes new responsibilities ….
    62. 62. Semantic Sensor Web (1) How to discover, access and search the data? Web Services - OGC Sensor Web Enablement (SWE)
    63. 63. Semantic Sensor Web (2) How to integrate this data together, when it comes from many different sources? Shared knowledge models, or Ontologies - syntactic models – XML (SWE) - semantic models – OWL/RDF (W3C SSN-XG)
    64. 64. Semantic Sensor Web Sensor Observation Ontology
    65. 65. Semantic Sensor Web The SSN-XG Deliverables • Ontology for semantically describing sensors • Illustrate the relationship to OGC Sensor Web Enablement standards • Semantic annotation of OGC Sensor Web Enablement standards
    66. 66. Semantic Sensor Web Linked Open Data: a community-led effort to create openly accessible, and interlinked, semantic (RDF) data on the Web.
    67. 67. Semantic Sensor Web Sensors Dataset • RDF descriptions of ~20,000 weather stations in the United States. • Observation dataset linked to sensors descriptions. • Sensors link to locations in Geonames (in LOD) that are nearby. near weather station
    68. 68. Observations Dataset • RDF descriptions of hurricane and blizzard observations in the United States. • The data originated at MesoWest (University of Utah) • Observation types: temperature, visibility, precipitation, pressure, wind speed, humidity, etc. 69
    69. 69. Linked Datasets procedure location Observation Location KB Sensor KB KB (Geonames) Example procedure location 720F Thermometer Dayton Airport • ~2 billion triples • 20,000+ systems • 230,000+ locations • MesoWest • MesoWest • Geonames • Dynamic • ~Static • ~Static 70
    70. 70. Semantic Sensor Web (3) How to make numerical sensor data meaningful to web applications and naïve users? Symbols more meaningful than numbers - active perception
    71. 71. Active Perception: • is an iterative, bi-directional feedback loop for collecting and explaining sensor data Explanation Observation Expectation Attention 72

    74. 74. Ohio Center of Excellence Knowledge-Enabled Computing (Kno.e.sis) SEMANTIC SOCIAL WEB
    75. 75. Everyone Wants to talk …and be heard! Hundreds and thousands of tweets, facebook posts, blogs about a single event, multiple narratives, strong opinions, breaking news.. 76
    76. 76. TWITRIS : Twitter+Tetris • Our attempt to help you keep up with citizen observations on Twitter – WHAT are people saying, WHEN, from WHERE • Puts citizen reports in context for you by overlaying it with news, wikipedia articles! 77
