The integration of informal semantics, generated using web 2.0 methods, with formal semantic
models, proposed by Semantic Web, can also be used in other contexts: for instance to facilitate
information access and retrieval. A typical case is the combination of folksonomies and
taxonomies. Folksonomies are classifications generated by users in a collaborative way, to
annotate and informally classify specific contents such as images, photos (e.g. Flicker) videos,
texts, etc. Folksonomies are therefore uncontrolled, bottom-up classification systems that emerge
from social tagging and reflect user mental models. Tags are defined by both content creators
and consumers, rather than by experts. Taxonomies are classifications, usually arranged in a
hierarchical structure, designed by specialized staff; they are accurate, precise and, at the same
time, rigid schemes which may produce ontological definitions.
