In this paper, we present an ongoing research about the design and development of interactive systems based on dialogues in natural language to assist a user during a visit to a cultural space. The responses of system contain multimedia elements and are generated by users’ queries or following contextual updates associated to their position, so the system can take initiative in absence of explicit stimuli. The response of system results from a composition process that coherently synchronises media elements with a synthetic voice delivering the textual content. This way, the visitor receives an audio explanation commented by images. To implement this approach, a semantic archive containing the annotation of stories has been built. The formalism used for the annotation is CSWL (Cultural Stories Web Language), used to represent cultural stories throug...

The HEI System is a system for events annotation and temporal reasoning in Natural Language Texts and media, mainly oriented to texts of historical and cultural contents available on the Web. In this work we assume that events are defined through various components: actions, participants, locations, and occurrence intervals. The HEI system, through independent services, locates (annotates) the various components, and successively associates them to a specific event. The objective of this work is to build a system integrating services for the identification of events, the discovery of their connections, and the evaluation of their consistency. We believe this interface is useful to develop applications that use the notion of story, to integrate data of digital cultural archives, and to build systems of fruition in the same field. The HEI system has been partially developed within t...

Many systems have been defined for this aim, but each one offers contents that has been strictly selected in the design phase. In this work, we present a platform to define and make programs that can be used for assisting a visitor by providing a particular interaction chosen during the visit.

During a museum visit, the visitors receive information about the cultural assets and responses to their questions. The aim is to reuse existing texts(for example those already published on the web) to compose responses for visitors that take into account the time at their disposal, and are balanced with respect to possible insights. Finally, system responses will result from a composition process that coherently synchronises media elements with a synthetic voice related to selected text.

Although usually considered as independent events, the single quantum release gives variable postsynaptic responses which not only depend on the properties of the synapses but can be strongly influenced by the activity of other synapses. In the present paper we show the results of a series of computational experiments where pools of active synapses, in a compatible time window, influence the response of a single synapse of the considered pool. Moreover, our results show that the activity of the pool, by influencing the membrane potential, can be a significant factor in the NMDA unblocking from Mg 2þ increasing the contribution of this receptor type to the Excitatory Post Synaptic Current. We consequently suggest that phenomena like the LTP, which depend on NMDA activation, can occur also in subthreshold conditions due to the integration of the dendritic synaptic activity.

In this paper, we present the design and implementation of a dialogue system to provide multimedia presentations for museum visits. A corpus of speech recordings in Italian was collected with a mobile application to obtain a reference set of possible ways for the users to express their intentions. On the basis of this corpus, a set of recurring syntactic patterns associated to device requests was extracted to let the dialogue system separate device commands from information queries. Disambiguation strategies depending on the context are also applied in presence of partial syntactic patterns. Information queries are answered by automatically assembling portions of semantically annotated texts and are synchronized with relevant multimedia resources. A case study on the ’800 exhibit at the ...
