Technological and Innovative Aspects
 Service Crawler
 Produces a snapshot of the part of the Web that is relevant for Web
Services, including both service descriptions and related information.
Deduplicates the WSDLs and creates unique service objects.
 Automatic Annotator
 Uses I nformation Extraction and Human Language Technologies to
analyse the crawled pages, annotate them semantically, and extract
important text and keywords
 Conceptual I ndexer and Matcher
 Stores both the textual extract of the crawled pages and the annotated
data from the automatic annotator and enables to query that data.
 Cluster Engine
 Tracks user behaviour to calculate user similarities and provides
recommendations by clustering services accordingly to their usage by
similar users.
 Service-Finder Portal I nterface
 Provides users with the interface to search and contribute to Service-
Finder. I t's based upon the STAR:chart Semantic Navigation framework.

Data to be shared and reused
 Service-Finder collects and refines service data
 4 subsets of data
 basic data (name, description, provider, provided operations,.. )
 monitoring data (e.g. availability, response time,..)
 automatic annotations (derived from the basic data) (e.g. service &
document classification,…)
 user contributed data (e.g. tags, ratings, comments,…)
 Accessible through
 Web portal (http://demo.service-finder.eu)
 API interface (UDDI & ebXM API s)
L
 RDFa annotations
 exported dump
 The Service-Finder technology targets also the application inside
companies to manage all the in-house Web services and grant a
unified and automatic access to them for the employees.
