Abstract: This study proposes a systematic approach to discovering new mobile service opportunities from related documents to overcome the weaknesses of previous methods based on the judgements of experts. At the heart of the suggested approach is text mining to explicitly specify the meanings of documents and information visualisation to effectively explore critical implications. Specifically, we integrate the strengths of principal component analysis (PCA) for mapping multi-dimensional data on a two-dimensional display and the merits of formal concept analysis (FCA) for grouping objects with shared properties based on the lattice theory. A case study of navigation services is presented to show the feasibility of our approach. We believe that the systematic processes and visualised outcomes offered by the proposed approach can enhance the efficiency of mobile service creation and serve as a starting point for developing more general models.
