This chapter examines new materiality perspectives to explore the influence of social media on young people’s music learning lives—their sense of identity, community and connection as they engage in and through music across online and offline life spaces. The aim is to provide an interface between activity, materiality, networks, human agency, and the construction of identities within the social media contexts that render young people’s music learning experiences meaningful. The chapter also emphasizes what nomadic pedagogy looks like at a time of transcultural cosmopolitanism and the positioning of youth-as-musical-resources who “make up” new musical opportunities collaboratively with people/materials/time/space. This involves moving beyond the notion of music learning as an educational outcome to embrace, instead, a nomadic pedagogical framework that values and supports the process of young people deciphering and making meaningful connections with the world around them. It is hoped that implications stemming from this discussion will provide insights for researchers, educators, and policymakers with interests in innovative pedagogical approaches and the creation of new learning and digital cultures in music education.

Latent Semantic Indexing(LSI) is an effective feature extraction method which can capture the underlying latent semantic structure between words in documents. However, it is probably not the most appropriate for text categorization to use the method to select feature subspace, since the method orders extracted features according to their variance,not the classification power. We proposed a method based on support vector machine to extract features and select a Latent Semantic Indexing that be suited for classification. Experimental results indicate that the method improves classification performance with more compact representation.

Clustering is an important unsupervised analysis technique for big data mining. It finds its application in several domains including biomedical documents of the MEDLINE database. Document clustering algorithms based on metaheuristics is an active research area. However, these algorithms suffer from the problems of getting trapped in local optima, need many parameters to adjust, and the documents should be indexed by a high dimensionality matrix using the traditional vector space model. In order to overcome these limitations, in this paper a new documents clustering algorithm (ASOS-LSI) with no parameters is proposed. It is based on the recent symbiotic organisms search metaheuristic (SOS) and enhanced by an acceleration technique. Furthermore, the documents are represented by semantic indexing based on the famous latent semantic indexing (LSI). Conducted experiments on well-known biomedical documents datasets show the significant superiority of ASOS-LSI over five famous algorithms in terms of compactness, f-measure, purity, misclassified documents, entropy, and runtime.
