A Semantic Landscape
© 2010. Access Innovations, Inc. All Rights Reserved.
Covering the
Semantic Landscape
! What is semantic?
! Semantic approaches
! Semantic process
! Semantic enrichment
! Beyond keyword search
! Social and Web 2.0 options
© 2010. Access Innovations, Inc. All Rights Reserved.
What is “Semantic” ?
! Process of adding meaning to objects
! We have lots of words
• What do they mean?
! LEAD
• Same spelling
• Different meanings in context
• Something to guide a horse
• An opening in the ice
• An element
• A management technique
• And more
2. © 2010. Access Innovations, Inc. All Rights Reserved.
Semantics infers relationships
! Between the words used and the textual
concepts represented
! Between different information objects
! Between different collections
! Supports data mining through the content
strata
! To extract the meaning at many levels
Semantics extraction
© 2010. Access Innovations, Inc. All Rights Reserved.
Semantic approaches
! Parallel paths
! Theoretical approaches vary widely
! Trouble defining our terms
! Controlled vocabularies
! Many standards bodies
! Funding agencies and approaches *
! Open source versus Off the shelf*
• * issues not covered in this talk
© 2010. Access Innovations, Inc. All Rights Reserved.
Parallel paths developed
! Computer Science
! Library Science
! Publishing
• Primary and secondary
• Abstracting and Indexing
! All developed structured data
! All added “Semantics” in different ways
! Dublin Core surprised the A&I’s
© 2010. Access Innovations, Inc. All Rights Reserved.
Theoretical approaches vary
! Independent silos developed
! Libraries - cataloging
! Secondary Publishers
• Abstracting and Indexing Services
! Computer Science
! Computational Linguistics
! Artificial Intelligence
! Translations – Multilingual meaning
! Other academic disciplines
© 2010. Access Innovations, Inc. All Rights Reserved.
Controlled Vocabularies
! To guide, not restrict
! Disambiguate
• what do you mean?
! Use synonyms for multiple paths to data
! Guide using related and narrower terms
! If a word is not in the CV?
• Type in the word! Use full text
• Add it to the CV
© 2010. Access Innovations, Inc. All Rights Reserved.
Defining our terms
! Keywords
! (HTML, Google)
! Uncontrolled
vocabulary
! Entities
! Authority terms
! Ontology
! Controlled vocabulary*
! Descriptors
! Thesaurus*
! Taxonomy
! Semantic enrichment
! Metadata
! Dublin Core*
*NISO Standards
3. © 2010. Access Innovations, Inc. All Rights Reserved.
Adding Descriptors
! Adding descriptors
• Historically too expensive
• Now we can do it automatically or assisted
! Recent recognition
• Library cataloging adds rich metadata
• Contributes to findability
• Full text is not very accurate
• Needs semantic layers
! Learning from the past practices
© 2010. Access Innovations, Inc. All Rights Reserved.
Many standards bodies
! ISO, ANSI, NISO (TAG 46) Z39.19
! ISO, BSI
! ISO, Tag 37, and CEBEMA X13
! W3C – World Wide Web Consortium
! Government consortia
! Other groups – MARBI, IFLA, DAMA, etc.
! Terminology Standards
• All developing standards
• Small amounts of cross walks between them
© 2010. Access Innovations, Inc. All Rights Reserved.
Some Controlled Vocabulary
Standards
! NISO Z39.19 – Controlled vocabularies
• Well formed following the standard parses as a
OWL Full
! ISO - Thesaurus data model and schema in
ISO/DIS 25964
! BSI - BS 8723- Structured vocabularies for
information retrieval
! W3C - OWL - Web Ontology Language
! W3C - SKOS

Ways to state
semantic relationships
! XML Elements and their attributes
! Dublin Core and its extensions
! Fields or tables in relational files
! MARC fields in cataloging
! RDF Triples from W3C
! All connect information semantically
! Most do not interact with the others well

A Taxonomy is a
Knowledge Organization System
! Uncontrolled list
! Name authority file
! Synonym set/ring
! Controlled vocabulary
! Taxonomy
! Thesaurus
! Ontology
! Semantic network

Semantic process
! Digitize your data
! Convert to textual strings
! Add metadata
! Add descriptors
! Deposit in repository
! Add search software
! Create a user interface
! Semantically enriched experience!

Semantic process adds value
! Organizes “unstructured” content
! Uncovers relationships
• between materials originating from different media
! Improves website navigation
• Addressing varied needs of visitors
! Suggests terms based
• Use popularity or user profile
! Focuses the search process
• Presents user with related terms
• Narrows broad topics
• Extract the meaning at many levels
© 2010. Access Innovations, Inc. All Rights Reserved.
Semantic Enrichment
! Start with a well-constructed vocabulary
• Leverage the power of the Knowledge Domain
• Associate terms with your unique brand and products
! Tag the content, people, and activities
• Subjects, names, places
• Automated or human-aided workflows
! Add end-user interfaces
• Enhanced Search: browse by subject; faceted display
• Discovery: Alerts, Visualizations, Related Content

Beyond Keyword Search
! After the single term Google box
! Structured data
• Has metadata
• Could have Semantic enrichment
• Taxonomy terms,
• Entities in authority form
! Structured systems have descriptor search
• Dialog, Ovid = fielded search
• Oracle, SQL, SAP, Access = table driven search
© 2010. Access Innovations, Inc. All Rights Reserved.
Kinds of search
! All Search is Boolean
! All use an inverted index
! Discovery – finding new trends and patterns
= 5% of search time
! Semantic Search – replicable, additive,
persistent, = 95% of search time
! 5% inspiration / 95 % perspiration
! Reinforce, support, update
© 2010. Access Innovations, Inc. All Rights Reserved.
Theoretical search divide
! Statistical, Bayesian, neural net, latent
semantic, vector = 50 % accurate so they
add rules and relevance
• Autonomy, Verity, Fast, Google,
! Semantic search rich in metadata, tags,
descriptors = 90 % accurate
• Endeca, Perfect Search, MarkLogic
• RDBMS Oracle, SAP, MS Access
• Dialog, Ovid, BRS, InfoSeek, Transium
! Federated Search – sends query to many
resources. One query – many sources
© 2010. Access Innovations, Inc. All Rights Reserved.
Measuring accuracy - guiding
! Recall / Precision
• Absolutes against a standard
! Relevance
• A confidence rating
! Semantics provide accurate results
! Speed and guide
• Hierarchies or Narrower terms to pinpoint
• Associated or Related terms to broaden
• Find stuff in other silos
! Combined silos without semantics = MESS

Semantic search options
6. © 2010. Access Innovations, Inc. All Rights Reserved.
Dissemination - then and now
! Follow through – get the word out
! Keep up
• RSS, Twitter, subscribe
! Who is linking to your work?
! Who’s referencing your work
! Who’s using your data?
! Who else is working in your space?
! Who’s quoting? What’s the impact factor?
! Who’s funding?
! Who’s implementing?
! Where are they?
© 2010. Access Innovations, Inc. All Rights Reserved.
Scientific social networking
based on metadata
! Idea has been here - Who is citing who like
! ISI does it with references
! API UniPHY does it using semantics
! Expand your options using
! good metadata and descriptors
Map who is working in the
field and where
See the authors connections

Not longer just “Nice to have”
! Semantic strategy is essential to a digital strategy
! Controlled vocabulary / taxonomy is central
! Strengthens brand
! Supports “unbundled” content
! The economy of the web is based around the
article, rather than the journal
! This trend is unlikely to change

! Use in search
! Use in discovery
! Use in social networks
! Use in production
! Use in e-commerce
! Use to serve ads
! Use on the web site
! Leverage what you’ve built!
