    2. 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. Seven Framework Programme © Service Finder Information Society Technologies (IST) Specific Targeted Research Project
    3. 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.
