The exposure can be done on the basis of the relationship between enterprises and/or people. The semantic web technologies can be used as the glue that helps in providing meaning and linking to enterprise data, services and user profiles. With such semantic enhance descriptions it is possible to employ vertical search on a predefined topic to get relevant and precise search results. The in-built reasoning capabilities of semantic web enables the system to deduce new facts from the existing facts. Today, many enterprises are adopting semantic web technologies into their software development life cycle to bring intelligence and smartness in the decision-making process. The semantic web technologies are being implied in many areas such as enterprise information integration, content management, life sciences and e-government. According to the gartner, the user of semantic web technologies in corporate, called as corporate semantic web, will reduce costs and improve the quality of content management, information access, system interoperability, database integration and data quality [23]. In our vision, we amalgamate cloud computing, social computing and semantic web technologies to expand the collaborative environment across enterprises boundaries and we commonly referred to Collaborative Enterprise Computing (CEC) as depicted in Figure 1. This fusion benefits enterprises Figure 1: Collaborative Enterprise Computing in many ways but low IT costs, correlate data of different enterprises and providing communication mediums (Blogs, Wikis, Social Network sites) are the most significant. The main rationale behind the CEC is to bring innovation through collaboration. Moreover, CEC ease the process of innovation by finding the trustworthy partners across enterprise boundaries who can be involved in the innovation process. These trustworthy partners are discovered/find according to their competences and experiences on the basis of criteria which can be given by enterprise. IV. CASE STUDY - INNOVATION STOCK EXCHANGE The objective of developing the innovation framework is to create a trusted network for collaboration in an open-controlled environment. Collaboration allows enterprises, governments, entrepreneurs, academia, and other business entities to come together from a closed environment to an open environment and create new ideas as depicted in Figure 2. Figure 2: Innovation through collaboration This innovation ecosystem fosters the innovation process and introduces new products and services to the market. Such members of the innovation ecosystem could have the opportunity to register their ideas and openly collaborate with people of their trusted network. This could also lead towards the innovation stock exchange as depicted in Figure 3 where investors could invest on highly ranked ideas for increasing the business opportunities. By leveraging the collaboration into Figure 3: Innovation stock exchange a case study under consideration the innovation ecosystem, enterprises will be able to develop innovative products and reduce their operational costs. For instance, Norwegian oil Industry reduced operational costs from 30-50% and enhanced productivity from 5-15% by integrating several operations together into their system [24]. Moreover, Procter&Gambler and Orange both has taken the initiative of collaboration by inviting people to present their ideas on a specific problem, and the most prominent idea was selected for the transformation into product [25]. Thus, significant revenue and customer satisfaction were acquired by both companies with innovation through collaboration. Current approaches are based on selected people from different organizations working together for a common goal. Our privacy-enhanced innovation framework will allow members of the innovation ecosystem to register an idea, assign scores from experts and find out trustworthy partners who can help in fostering the innovation 2011, © Copyright by authors, Published under agreement with IARIA - www.iaria.org 4

Assume Bob has an innovative idea, which he registers it in the system so that he could get right partners who could collaborate to transform the idea into realization. Idea will be reviewed for acceptance by the experts that belong to different enterprises. The idea will be published categorically according to the nature of its topic. The system will find experts in that topic by employing idea owner polices and criteria. The system will send notification to experts via email or sms and consider them to assign scores. The system facilitates Bob in finding trustworthy partners with whom he could collaborate for the realization of the idea regardless enterprise premises. Furthermore, the high-score idea will be published in the innovation stock exchange where members could open a vital investment opportunity. Thus, the system not only helping Bob in finding the right partner for his idea but also providing him implicit technical review, scientific value and the importance of his idea. V. ENTERPRISE COLLABORATION ENABLEMENT This section outlines how an automated and trusted collaboration can be enabled in an enterprise. A. User Profiling User profile plays an important role for enabling automated collaboration beyond enterprise perimeter. User profiling generally involves profile setup, manipulation, and synchronization. In profile setup a basic user profile is created with explicit user feedback. The profile setup procedure can get user social network sites membership information from user basic profile, allowing profile setup mechanism to retrieve more information about user’s preferences, groups and friends. In turns, this leads to implicit user feedback, where user information is collected without any intervention of user. The profile manipulation consists of create, read, update, and delete functions. The profile synchronization keeps update of all distributed profiles. ETSI [26] , 3GPP GUP [11] and MAGNET Project [27] among others are first initiatives towards standardization of user profile structure. However, these aforementioned research initiatives do not aim for collaboration. They mostly focus on personalized services. Whereas, in this outlook we specifically focus on user profile in the context of enterprise collaboration. We extend the user profile ontology proposed in [35], which classify the profile into different categories. Each profile contains relevant information according to its category and comprises authorization policy to restrict its access to third parties. For instance, corporate profile contains person’s professional skills and expertise in a specific topic. This profile can only be accessed by third parties (i.e., colleagues, friend from trusted-virtual company etc.) to whom the permission has been granted. In this manner, a person can explicitly choose what to share and with whom to share his profile. Currently, we have defined one core concept Profile, which contains subclasses: (i) personal Profile, (ii) social profile, (iii) corporate profile, (iv) public profile and (v) private profile of it. A simplified snapshot of the user profile ontology is depicted in Figure 4. B. Trust Modeling Figure 4: User Profile ontology While Trust is relative term, which is defined differently in literature according to the nature of the work. In [28], author defines ”Trust in a passionate entity is the belief that it will behave without malicious intent”. In [29], authors consider context as an important factor for establishing trust by defining, ”Trust is the firm belief in the competence of an entity to act securely, dependably and reliably within a specific context”. In this paper, enterprise establish trust between their partners and co-workers to collaborate with each other for improving the quality of work and minimizing the risk factors. Thus, we define trust in such a way where the trusting agent has belief on trusted agent capabilities (see Figure 5) on the basis of relationship with the trusted agent for collaboration in order to realize a specific business opportunity. Figure 5: Definition of trust We consider four factors context, time period, relationship and trust value that influence enterprises to obtain trusted partners for collaboration. The context is the situation or scenario for enterprises such as writing a research proposal, sharing new idea, discussing recent activity. Time period is a time at which one person interact with the other person and afterwards assign a trust value to it. For instance, one can 2011, © Copyright by authors, Published under agreement with IARIA - www.iaria.org 5
