1 - IoT Compositions by and for the Crowd

JCIS_2015_submission_10The Internet of Things (IoT) offers a new eco-system of heterogeneous and distributed services that is available anytime and anywhere and that can be potentially accessed by any properly connected device. However, these available services are usually consumed in isolation, missing the potential that their combined usage can bring as new added-value services. In addition, the massive end-user adoption and usage of smartphones together with their powerful capabilities turn this type of devices into a promising platform to develop and execute these added-value services compositions. Moreover, end-users are nowadays getting more and more familiar with technology, fact that allows them to participate more actively in the development of new types of applications. However, this will not happen until we provide end-users with more powerful and easy-to-use tools. To this end, this paper presents an architectural solution to allow end-users building IoT services compositions by just focusing on domain-logic issues.

2 - A Mobile End-User Tool for Service Compositions

With the advent of Web 2.0 and the massive adoption of smartphones, end-users are more keen to actively participate in the creation of content for the Internet. In addition, the big amount of data that the Internet of Things can bring to it, establishes an ideal framework to allow end-users not just consuming data but also creating new valueadded services. To achieve this, in this work we propose the development of an end-user tool for smartphones capable of composing services that are available in the Internet.

3 - Feature Modeling to deal with Variability in Business Process Perspectives

The construction of Business Process (BP) models entails big challenges, especially when BPs contain many variations. In addition, BPs can be seen from different perspectives, i.e., the behavioral (i.e., control-flow), the organizational (i.e., resources distribution), or the informational (data-flow) perspectives among others. Depending on the context where the BP is taken place, we may found variability in any of these perspectives. Different approaches to model variability in BP perspectives have already been proposed. However, these approaches are highly tight to the modeling language. In addition, they focus mainly on the behavioral perspective. To deal with variability in other BP perspectives in a more flexible manner, this work proposes an approach based on feature models. These models do not only allow enhancing expressiveness regarding BP variability, but also the maintenance and understanding of the resulting process model.

4 - Defining PPIs for Process Variants based on Change Patterns

Business Process (BP) families are made up of BP variants that share commonalities but also show differences to accommodate the specific necessities of different application contexts (i.e., country regulations, industrial domain, etc.). Even though there are modelling techniques to represent these families (e.g., C-EPC, Provop), there is no work aimed at the performance measurement of the different BP variants that conform the family. Process Performance Indicators (PPI) are commonly used to study and analyse the performance of business processes. However, the application of such indicators in BP families increases the modelling and management complexity of the whole family. To deal with this complexity, this work introduces a modelling solution for managing PPI variability based on the concepts of change patterns for process families (CP4PF). The proposed solution includes a set of patterns aimed at 1) reducing the number of operations required to specify PPIs and 2) ensuring PPI family correctness.

5 - Opening up Context-aware Services Compositions to End-Users

The interconnected world in which we live opens many possibilities to create, consume, and share knowledge and services. Even though end-users are more than ever prepared in terms of technology (e.g., by using smartphones), their specific context (i.e., personal interests, geographical location, etc.) is not yet properly considered in existing solutions to explore these possibilites. Therefore, we need to provide end-users with tools that allow them to create, consume, and share added value services by using the proper knowledge and services according to their context. In this sense this paper discusses how existing solutions could be integrated to achieve this goal. In particular we explore the possibility of extending EUCalipTool, an end-user mobile tool for service compositions, with the context-aware notification capabilities offered by nimBees.

7 - Towards a Social End-user Composition of Services

Nowadays, end-users’ environment is plenty of services that support their life style, and involving them in the process of service creation can allows them to benefit from a cheaper, faster, and better service provisioning. There are already tools targeted to the authoring and
consumption of services. However these tools consider end-users as isolated individuals, missing the potential that their social environment can bring to them. In this paper, we investigate how social networks can be used to improve the authoring and consumption of services by end-users. We propose a social network of service compositions as a valuable
mechanism to share knowledge among end-users in order to improve their skills in composing new services. In addition, we analyse the underlying relationships created among service compositions in order to provide end-users with an intuitive way of browsing them.

9 - Enhancing EUCalipTool Service Composition through Natural Language Processing

Although end-users have available a lot of on-line services to be con- sumed individually, it is their composed usage what has the potential to create new value-added services for end-users. In this sense, many efforts have been done to allow end-users to compose the services that they need by themselves. However, most of these solutions present two main problems: (1) they provide little support to help end-users to browse interminable lists of services, and (2) they present the blank piece of paper problem, which appears when end-users have to face an empty canvas to define a composition without any help to find the services that better fit their needs. In this paper, we present a solution to im- prove these problems by using natural language processing techniques in order to search and select the services end-users need to accomplish a specific goal. This solution has been implemented in the context of the EUCalipTool platform.
