A New Similarity Search Approach on Process Models
We investigate the problem of similarity search query in process model repositories: given a certain target model, compare with the process models in the repository and find their similar pattern. We seek to find an effective way to mine out the similar patterns. Using four representative models, we evaluate a new approach, with semantic and topological consideration accordingly. The experimental results show that the combination of semantic and topological analysis brings higher retrieval quality in the similarity search on process models.
This article discusses different ways in which users may be involved in the ideation phase of service innovation and the results and limitations of such involvement. The study compares the use of a blog and two differently setup future workshops one with users only and the other with a mix of users and employees in a library. The authors' study shows that the blog is efficient in giving the users voice whereas the mixed workshop method involving users and employees is particularly efficient at qualifying and further developing ideas. The findings suggest that methods for involving users in ideation should be carefully selected and combined to achieve optimum benefits and avoid potential disadvantages.
