are sponsored by The Andrew W. Mellon Foundation
4. A Quick Look at SEASR
• Addresses:
– Challenges of transforming informa9on into
knowledge
– Construc9ng the soGware bridges to move from
the unstructured and semi‐structured data world
to the structured data world.
• Aims:
– Make digital collec9ons more useful
– Provide access to relevant analy9cs and
visualiza9ons
– Enable easy mashability via SOA
5. SEASR: Reach + Relevance + Reuse + Repeatability
SEASR emphasizes flexibility, scalability, modularity, provides
community hub and access to heterogeneous data and
computa9onal systems
– Seman9c driven environment for SOA interoperability
– Encourages sharing and par9cipa9on for building communi9es
– Modular construc9on allows flows to be modified and configured to
encourage reusability within and across domains
– Enables a mashup and integra9on of tools
– Data‐intensive flows can be executed on a simple desktop or a large
cluster(s) without modifica9on
– Computa9on can be created for distributed execu9on on servers where
the content lives
– User accessibility to control trust and compliance with required copyright
license of content
– Relies on standardized Resource Descrip9on Framework (RDF) to define
components and flow
7. Workbench
• Web‐based UI
• Components and flows
are retrieved from server
• Addi9onal loca9ons of
components and flows
can be added to server
• Create flow using a
graphical drag and drop
interface
• Change property values
• Execute the flow
9. SEASR @ Work – Zotero
• Plugin to Firefox
• Zotero manages the
collec9on
• Launch SEASR Analy9cs
– Cita9on Analysis uses the JUNG
network importance algorithms
to rank the authors in the cita9on
network that is exported as RDF
data from Zotero to SEASR
– Zotero Export to Fedora through
SEASR
– Saves results from SEASR
Analy9cs to a Collec9on
• Launch MONK Processing
– MONK DB Inges9on Workflow
12. SEASR @ Work – Audio Analysis
• NEMA: Executes a SEASR
flow for each run
– Loads audio data
– Extracts features for every
10 sec moving window of
audio
– Loads and applies the
models
– Sends results back to the
WebUI
• NESTER: Annota9on of
Audio via Spectral
Analysis
14. SEASR @ Work – DISCUS
• On‐demand usage of
analy9cs while surfing
– While naviga9ng
request analy9cs to be
performed on page
– Text extrac9on and
cleaning
• Summariza9on and key
work extrac9on
– List the important
terms on the page
being analyzed
– Provide relevant short
summaries
• Visual maps
– Provide a visual
representa9on of the
key concepts
– Show the graph of
rela9ons between
concepts
