Plot lies at the core of the framework. Each plot takes place in a specific context and involves
some entities, while different plots are semantically related in terms of sequence or overlap. In
a specific plot annotation area within an image, a dynamics is normally used to present dynamic
features of the plot. The descriptive framework, as a whole, is an abstract semantic annotation
model and accomplishes the semantic description and annotation by mapping annotated objects
onto the abstract model. Plot constitutes the core of the annotation framework and corresponds to
the Body of OAC in image annotation.
In detail, temporal semantic relations between plots contain nextplot, lastplot, overlaps,
meets, starts, during, finishes, equal. In addition to the above relations, other obscure and
abstract spatio-temporal semantic relations can also be identified in plots. This paper places
TemporalSpatialEntity under the category of Entity. To meet the need for annotation of spatio-
temporal information in narrative images, this paper divides TemporalSpatialEntity into Place and
TemporalThing, which are respectively further divided into two types-Concrete(ConcretePlace,
ConcreteTemporalThing)and Abstract(AbstractPlace, AbstractTemporalThing). Dynamics is
another indispensable element in the model. As a core sub-category in the process of annotation,
Action has two object properties, namely hasActor and hasRecipient；the former being the
agent of the action while the latter the patient. At the same time, Dynamics can also have a
type(DyanmicsType). Context is a special item in the plot annotation of narrative images, and
it provides the annotation model with additional extension ability. Instead of being directly
accessible from image, information involved in context is hidden behind the image, yet helpful in
understanding the image.
To represent the complex relations of overlap between different annotated areas within an
image, this paper puts forward OAC extended vocabularies, including no-overlap, complete-
overlap, inclusiveness, and partial-overlap. In the end, this paper performs a semantic annotation
experiment on Dunhuang narrative murals, using an image semantic annotation tool embedded
with the model, and the annotation data is converted and stored in the form of RDF triples. The
experiment verifies the model’s reliability and applicability.

Study on the antecedents of social trust in public e-information service

Public e-information service is the inevitable outcome driven by the deep integration of
information technology and public information service across all walks of life. As the penetration
of public e-information service increases, the focus of public concern has transferred from
information disclosure to service trust. Trust has been an essential antecedent for public to adopt
