Citation Indices
Citation indices are a way to compare:
Authors and scholars
Journals within the same field
Articles within a field
Eigenfactor map example Uses for knowledge visualization The h -index is graphed by most online citation indexes, to compare scholars within a field. Other projects have used the information in citation indexes to visualize relationships between fields, as above.

THESAURI ~ THEIR STRUCTURE AND USE Acknowledgments Google Images. Amanda Piekart, Michelle Strassberg and Carla Edwards A Brief History of the Thesaurus Derived from the Greek “Thesauros,” which means “treasury or storehouse.” Many thesauri are now available on the Internet. They are important for creating a “controlled vocabulary” when conducting searches.
Why Thesauri are important
Create a “controlled vocabulary” for searching
Help locate “preferred terms” used by the particular search engine or database
Aid in producing best results from searching
Address a specialized audience

How Thesauri are used
Most are available in print and online versions
Inputting keywords will lead searcher to preferred terms
Special Features
Can search in a variety of ways

Ontologies and Digital Libraries Nicholas C. Jackson & Erin Elliot What is an Ontology “ What exists is that which can be represented! ontology is the study of what is real, what is reality, and or what existence” (Gruber,1). “An ontology is an explicit description of a domain; concepts, properties and attributes of concepts, constraints on properties and attributes, individuals” (Noy, 2). Ontology Engineering “ Defining terms in the domain and relation among them. Defining concepts in the domain (classes), arranging the concepts in a hierarchy (subclasses-superclasses hierarchy), defining which attributes and properties classes can have and constraints on their values, defining individuals and filling in values.” (Noy, 3). PRATT Uses in digital libraries “ The ontology enables concept-based searching that can improve precision of results far beyond common keyword matching” “The ontologies has the potential to offer navigation support that would facilitate the seeking process…” It “provide a conceptual structure that” organization and arrangement information (2006, Patuelli, 4). Ontology vs. Vocabulary, Taxonomy, and Thesauri “ A controlled vocabulary is a list of terms. A taxonomy is a collection of controlled vocabulary terms organized into a hierarchical structure. A thesaurus is a networked collection of controlled vocabulary terms. A formal ontology is a controlled vocabulary expressed in an ontology representation language” (Jernst, 1). PRATT Jernst. (2003). What are the difference between a vocabulary, a taxonomy, a thesaurus, an ontology, and a meta-model? McGuinness, D. L. (2003). Ontologies Come of Age.

Tags: terms used to identify resources for retrieval; created and defined by users who are both the providers of content and the end-users
Folksonomies: composed of user-generated metadata, created by tagging pieces of digital information with their own searchable keywords
broad: third-party users assign tags to the same content, creating metadata for their bookmarks; sites aggregate this metadata, make it searchable
narrow: users tag their own content so that they can easily retrieve it and help others find it; useful for assigning metadata to unique content
Museum/Archival Applications
Value
Tagging: dialog between viewer and work as well as viewer and museum
Encourages personal interpretations of work
Fosters/maintains museum relationships
Serves altruistic purpose of museums
steve.museum (www.steve.museum)
Collaborative research project (launched in 2005) that explores the potential for tagging within the context of museums.
Goals:
Motivate users to tag, guide them through the process, and reward them when done (create prolonged and repeat use by giving users control)
Integrate contributed data into local documentation systems to improve access to collections
Encourage engagement with cultural content
Traditional Library Applications
Venues
Social Networking Sites
GoodReads
Information Management Sites
LibraryThing
PennTags
Directions
Towards a shelfless library
Items in multiple “locations”
Towards a personal experience
Evocation of personal feelings
Movement away from Library-centeredness
PennTags
Emergence of Folksonomies
Traditional subjects reaffirmed
Traditional facets reaffirmed
New descriptors emerge
Personal descriptions
New representations of the traditional emerge
Innovative combinations
Tagging & Folksonomies Social Applications
Value
User-generated vocabulary based on personal understanding of object
“ Placing Hooks”
Serendipitous browsing capabilities
Inexpensive way to create order and community
Examples

Photo sharing and management site

Social bookmarks manager
Broad
Limitations
No synonym control
No hierarchal structure
Do not consider the future
Pros:
supplements traditional cataloging by increasing access points, findability
encourages discovery/rediscovery and sharing of information
Cons:
no controlled vocabulary, synonym/homonym control; lack of hierarchy
tags may be imprecise, ambiguous, inconsistent, or overly personal
Goals: introduce controlled vocabulary to tagging systems; tools should be simple, efficient and not require large investments of capital; they should make it easier to locate new and older materials and allow reuse/remix of content and data to produce new collections and online tools
Cataloging Cultural Objects (CCO) Introduction to CCO Historical Overview Recommended Elements Managing Content & the Future of CCO
Cultural Heritage
Created by members of a culture
Found in texts, objects, images, etc.
Universal access benefits the community
Need for CCO
Attempted to use MARC & AACR, which fell short
Community created a shared element set (VRA Core) in 1990’s
Recognized need for data content and data format standards
Museums needed a more compact element set for exchanging data
Working Together
Forums organized by the National Initiative for a Networked Cultural Heritage
VISION & REACH project
VRA & CCO project
Purpose
Provide guidelines for cataloging cultural objects
Promotes good descriptive cataloging, shared documentation, and superior end-user access
Assists in the development of in-house cataloging rules or manuals.
Serves as a guide to building consistent cultural heritage documentation in a shared environment.
Audience/Users
Museum catalogers, curators, archivists, librarians

Personal Information Management Matt Flaherty, Jessica Brooks, Maggie Balistreri
Since the Beginning
An issue ever since information has been available
It is the practice and study of acquiring, organizing, maintaining, and retrieving of personal information items
Personal Information Management Tools (reflects individual needs, preferences, and styles) E-mail: file organization, filters, chatting Calendar: reminders, calendar sharing Computer desktop: file finder tools, widgets Internet: search engines, RSS feeds Websites, Wikis, & Blogs: circulating information versus absorbing information Figure 2. Structure of Information System (Barreau, 1995). Figure 1. Ten Commandments. Key Image 1 Key Image 2 Figure 3. Before utilizing computer PIM tools. Figure 4. After utilizing computer PIM tools. Meta PIM: The PIM of a PIM Project Three individuals collaborate on a Personal Information Management project. Each uses, and all coordinate using, the following tools: E-mail, calendar, phone/text messaging, personal computer/desktop, Internet search tools, and a Wiki . Figure 5. PIM Wiki for PIM Group Project. Implications of PIM Save what? More digital space means we can save everything. Save where? Data saved across multiple tools benefits from an integration method. Retrieve how? Saving more and more personal information results in increased reliance on robust search tools, tagging, and metadata. References Barreau, D.K. (1995).

An Information System
PIM Systems have the same key components as other information systems such as catalogs and indexes
However, PIM differs because it is designed to meet the needs specific to an individual and not the general needs of multiple users
