        Mashups are next generation of web applications. A mashup is a lightweight web application that is created by combining information or capabilities from more than one existing resources to deliver a new and integrated experience to the user. Mashups introduce a new class of integration techniques in enterprises for implementing situational applications (i.e. applications that come together to solve an immediate, transient and specific business problem). In a dynamic, complex and competitive enterprise environment, it is impossible to predict and create all the future integrated applications. Enterprise mashups as a simple and quick solution helps small teams and individuals in an organization with limited knowledge in programming to create their desired integrated applications by combining and reusing internal resources of organization with resources published on the Internet. Currently there are many tools proposed by different software vendors to facilitate creating enterprise mashups. Although these tools facilitate creating enterprise mashups to some extent but still needs the mashup end-user to have some experiences in web technologies, information security and data structures of mashup components. Furthermore, the generated mashup is dependent on its components, so change or replacing a component is a complex and time-consuming task. This issue will be exacerbated in enterprise mashups that are created by knowledge workers. In this research, we aim to make creation of enterprise mashups semi-automatically by combining SOA (Service- Oriented Architecture), Semantic Web and Web 2.0 technologies. In addition, we propose a novel annotation mechanism to apply semantic descriptions and enterprise policies to the generated mashup. Manuscript profile

        In order to provide for the necessities of life, human beings always use the advice and suggestions of others, which are provided orally or in writing, and take them into account in their decisions. Today, with the advancement of technology and the expansion of e-business in the context of Internet websites, a new chapter of digital life has begun with the help of advisory systems. The most important goal in these systems is to attract customers and gain their trust by offering the best and most appropriate offer to buy products, according to their interests and tastes in the midst of a multitude of choices. In this research, an attempt has been made to extract information related to the field of film with the help of connections in DBpedia's ontology. Then the structure of the recommender system is designed and implemented and with the help of the information available in the MovieLens database, the performance of the recommender system is evaluated. According to the evaluations, the proposed model is more efficient among other methods that somehow use the semantic web. Manuscript profile
