Why The Idea of Discovery Introduce?

“ … socialize or interact with each other in the online

world … ”

“… have the potential to promote participatory

networking where both information services and patrons

communicate, collaborate and co-create content in their

areas of interest. ““… investment in this area will increase libraries’

online popularity and visitorship.”

Because …

Information Concierge: The Ideal Model?

Adopted from Flickr User Model . Bryce Glass (2005)

Information Concierge: The Ideal Model

6

“.. libraries could enhance their current role in supporting their

respective user communities and life-long learning through

performing the role of an info-concierge, or as a network of

inter-connected info-concierges and true collaborators.”

(Foo, Ng, & Soh, 2008).

Information Concierge: The Ideal Model

“… with this model,

can Librarians seen as a community partner ?”

Who are our key Library users?

Educating the Net Generation . Oblinger & Oblinger, (2005):  

“… the Net Generation makes up

the majority of patrons in NTU

Library and they have a common

characteristic in terms of finding

and use of information

resources.”

Information Searching Behaviour

9

The characteristics of this group gravitate towards

the following traits

(Oblinger & Oblinger, 2005):

- Preference for group activity

- Believe it’s cool to be smart

- Are fascinated by new technologies

- Are focused on grades and performance

- They are most likely to consult each other

- Are busy with extracurricular activities

ContentThese services harvest content from local and remotely hosted repositories

and create a vastly comprehensive centralized index—to the article level—

based on a normalized schema across content types, well suited for rapid

search and retrieval of results ranked by relevancy. Con-tent is enabled

through the harvesting of local library resources, combined with brokered

agreements with publishers and aggregators allowing access to their

metadata and/or full text content for indexing purposes.

Discovery These services have a single search box providing a Google-like

search experience (as well as advanced searching capabilities).

Delivery

These services provide quick results ranked by relevancy in a modern

interface offering functionality and design cues intuitive to and expected by

today’s users (such as faceted navigation to drill down to more specific

results).

Flexibility These services are agnostic to underlying systems, whether

hosted by the library or hosted remotely by content providers. These

services are open compared to traditional library systems and allow

library greater latitude to customize the services and make the service its

own.

The Evolution of Communication

18

The Main Core of Communications

19

Library Catalogue is the main core

of communication

Web search is our communication

presentation layer

Discovery Needs to

takes in place

Supporting system to the

communication

But, we have Federated Search

20

PATRONS

Librarians

What is Federation Search

21

(1) transforming a query and broadcasting it to a

group of disparate databases or other web

resources, with the appropriate syntax,

(2) merging the results collected from the

databases,

(3) presenting them in a succinct and unified

format with minimal duplication, and

(4) providing a means, performed either

automatically or by the portal user, to sort the

merged result set.

What about Web Discovery, then

22

A discovery service is a search interface to

pre-indexed meta data and/or full text

documents.

Discovery services differ from federated

search applications in that discovery services

don’t search live sources.

By searching pre-indexed data discovery

services return search results very quickly.

Discovery services are touted as an

evolution beyond federated search and in

some ways they are.

Some discovery services either provide

integration with federated search or provide

an API for others to do the integration

What about Web Discovery, then

23

At this stage, even they are able to search certain

databases Web Discovery is still in the process of

development and refining, the platform is a suitable

evolution for the Next-Gen Library Catalogue.This is because we are only able to search metadata

from a pre-index data and not live fulltext searching.

Never less, the cumulative traffic has increased access

tremendously to the over visitorship of the digital library.

The reason of ease of use and friendly user interface.

Web-scale discovery (WSD) Concept

24

The Ins and Outs of Evaluating Web-Scale Discovery

Services

by Athena Hoeppner (1) the web-scale discovery platform:

 

- Single search across the central index

- Fast response time

- Relevancy-ranked results list

- Facets, sort, and other tools for refining and using the results

- Connections to full text via direct links and OpenURL

- End-user accounts and features

(2) the central index may include these elements such

as,

(i) library supplied data,

(ii) open access and public domain data,

(iii) publisher metadata and full text,

(iv) web service discovery-licensed material and (v) mutually licensed.

(3) the discovery layers such as,

(i) branding and customisation, (ii) searching, (iii) advance discovery, (iv) relevancy and refinement,

(v) end-user features and web 2.0 and lastly (vi) enhancement.

Learning Experiences

25

Discovery Layer

Relevancy Ranking:

- Does the relevancy expose the kind of material important to

the users?

Search/Discovery Tools:

- Do the basic/advanced options, facets, and limiters enable the

users to find the content they seek?

End-User Features and Controls:

- Do the folders/lists, tagging, exporting citations, and other

features support user interaction with the content?

Interface customizations:

- Can librarian control the branding and layout, include widgets,

and use APIs?

Results Enrichment:

- Is it possible to enhance the results with book jackets, external

information, and recommenders?

Overall Usability:

- Do users understand the interface and make good use of the

options?

Central Index

Mutually Licensed Content:

- Does the central index help expose the rich

metadata from the current subscriptions?

Item Types:

- Does the central index include item types important

to the library?

- Are the results full of item types that user do not

want?

- Is content from specialized indexing - -searchable?

Full-Text Indexing:

- Does the central index include the backfiles for

journals and have searchable full text for a variety of

sources?

Take away note

(i) the need of web discovery tool,

(ii) the choice and administration of the tool,

(iii) the strength and capability of the discovery tool

(vi) the challenges of the discovery tool and

(v) the return of investment in implementation of the discover

tool.
