Human-Provided Services (HPS)
Last update: August 18, 2009
Description
The Web is evolving in a rapid pace allowing people to form Web communities depending on their interests. Management of interactions becomes increasingly complex as current tools only support messaging and addressing mechanism developed for the early Web. It is difficult to manage interactions ranging from ad-hoc to process-centric collaborations.
The Human-Provided Services (HPS) framework enables humans to publish their skills and capabilities as Web services. Not only interactions
between humans are supported by using HPSs, but also interactions with software services, for example, human interactions in BPEL4People-like processes. The main
contribution of the framework is the ability to define HPSs as Web services and furthermore tools to manage interactions. These interactions range from ad-hoc to
process-centric collaborations. HPS is a powerful tool because it enables a versatile mix of software and Human-Provided Services.
Architecture
The architecture of the HPS framework (see Figure below) comprises tools for designing Human-Provided Services, the Runtime
enabling discovery and interactions, and the API and Middleware Layer.
Features
The main features of the HPS framework are:
- End-user centric design tools for Human-Provided Services
- Mashup like design of HPS without requiring programming skills
- Recommender algorithm to support the design of HPSs
- Support of XML and Web service standards
- WSDL, WS-Addressing, SOAP, and automatic GUI generation based on W3C standards such as XForms
- Runtime interaction support
- Activity-centric interfaces to manage interactions in a pervasive manner
- Ranking of human and software services
- Activity and context-sensitive link analysis algorithms
- Personalized PageRank based on contextual skill and interaction intensity measures (see interaction mining)
