This chapter presents a users perspective regarding the potential applications of the searchcomputing technology for biomedical discovery. Recent research on human inherited diseases has increased the number of information resources useful to bridge medicine and biology and to associate genotype and phenotype. The application of the searchcomputing technology is discussed in the frame of a number of techniques that can be applied in Life Sciences for managing distributed biomedical data: Federated databases, Grids. Cloud computing, Web Services. Workflow. Particular attention is then devoted to challenges and opportunities deriving from the application of ranking and the management of missing information. Finally, the definition of a standard score function. that could be adopted by all service providers in order to merge all the collected scores for the searchcomputing, and the combined use of workflow management systems and searchcomputing, are discussed.

searchcomputing queries typically address search tasks that go beyond a single interaction. In this paper, we show a query paradigm that supports multi-step, exploratory search over multiple Web data sources. Our paradigm requires users to be aware of searching over "interconnected objects" with given semantics, but each exploration step is simplified as much as possible, by presenting to users at each step simple interfaces, offering some choices that can be supported by the system;choices include moving "forward", by adding new objects to the search, or "backward", by excluding some objects from the search;and the selection and de-selection of displayed results in order to dynamically manipulate the result set. For supporting exploration, we designed a new architectural element, called query orchestrator, which connects the user interface module with the execution engine;the orchestrator maintains the history of the query session and caches query results for reuse at subsequent interactions.

While the web is often described in terms of access to information, it is also a place where people do things from booking hotel rooms, to completing their tax return. This paper outlines the ways in which search can form a part of a more action-based view of web interaction. The simplest is that search can be action that the user is performing to get information. However, search can also be used more computationally within an intelligent system that infers appropriate points to trigger interaction (loci of action) and constructs a model of the users context. The resulting picture is a rich interplay between user action and computation, where each inform and influence the other, and where search can form an intimate part both explicitly for the user and embedded within computation.

In the searchcomputing project, Web services are modeled by the Semantic Resource Framework (SRF). In this article, we argue that the SRF could benefit from ontological concepts borrowed from the Semantic Web. We first present the knowledge representation used in the Semantic Web, notably in the YAGO ontology [14]. We show how this model is used in the ANGIE system [12] to represent Web Services in conjunction with YAGO. We draw parallels to the Service Mart [3] model used in SeCo. We propose a symbiosis of the two models, discussing the challenges and advantages that come with the integrated model.

This chapter presents our experience in applying User Centered Design methods to identify several design opportunities for future searchcomputing applications. The chapter starts introducing the definition of User Centered design, its principles and methodologies. It presents the five steps process we followed in order to get user behavioral insights and design opportunities. It illustrates each phase that composes the research process focusing on the visualization of the user experience and on the design questions we were able to identify by analyzing it. The core contribute of the chapter is in proposing answers to the design questions in the conference travel context for two user profiles: the Fast&Furious and the Discover&Learn.

This paper reports the main findings of a panel about trends in search engine interaction, focused upon the use of search engines for performing complex processes'. The discussion focuses on the different evolutionary path followed by search engines with respect to other Web and information management solutions, making end users acquainted with the simplistic and never changing keyword-based query paradigm. The analysis delves into the pros and cons of personalization. contextualization, and exploration of Web information, with special attention to the presentation and user interaction aspects. In the end, we also wonder if the keyword-based query paradigm will ever change.

While mashups may integrate into a new web application data, application logic, and user interfaces sourced from the Web - a highly intricate and complex task - they typically come in the form of simple applications (e.g., composed of only one web page) for individual users. In this chapter, we introduce the idea of distributed user interface orchestration, a mashup-like development paradigm that, in addition to the above features, also provides support for the coordination of multiple users inside one shared application or process. We describe the concepts and models underlying the approach and introduce the MarcoFlow system, a platform for the assisted development of distributed user interface orchestrations. As a concrete development example, we show how the system can be profitably used for the development of an advanced, collaborative search application.

The SeCo project is dedicated to the support of investigation-driven frontier research on searchcomputing and its prime objective is not to develop a commercial venture. Still, not considering the possible market exploitation of such a project could be misleading also in terms of technology investigation. At the half of the project, when many technology and research decisions still must be taken, it is important to consider also the possible implications of such decisions on possible future business models. The present chapter is aimed at understanding the possible future trajectories for the exploitation options of the SeCo project. The chapter starts identifying roles and capabilities of a potential SeCo value chain. The second step is defining some archetypal Business Models investigating the option of having some of the previous roles not managed internally but delegated to the external market. Finally the business models are compared and recommendations for the following of the project are drawn.

The Semantic Resource Framework (SRF) is a multi-level description of the data sources for searchcomputing applications. It responds to the need of having a structured representation of search services, amenable to service exploration, selection, and invocation. The SRF aims at extending the Service Mart model used so far in searchcomputing to overcome some of its limitations. The main new features include external attributes, which represent the input to be provided by users for accessing objects;selector attributes, describing the possibility to map the same access pattern to different services based on some condition;key attributes for objects;and a generalized notion of nearness between objects. The high-level view presented by SRF is a very simple Entity-Relationship model with objects and binary connections, that can be used for very different query tasks, ranging from custom search applications (i.e. predefined queries) to exploratory search (i.e., exploration of its objects and connections) to natural language interfaces (i.e., query dialogues). Such high-level view should be considered as an initial step in the enrichment of the service repository with additional semantic capabilities.

In this chapter we provide our personal vision of what could be the next generation of Web search engines, outlining the main researchchallenges that derive from it. This vision is based on a single premise: people do not really want to search, they want to get tasks done. We motivate our work by the current trends in the Web and, in particular. Web search.
