Move Cultural Heritage Knowledge Graphsin Everyone's Pocket

This repository behaves as a support material for the paper entitled "Move Cultural Heritage Knowledge Graphsin Everyone’s Pocket" submitted (and under evaluation) as a **Application report** for the *Cultural Heritage and Semantic Web* special issue at the Semantic Web journal. 

It provides a Permanent URI for the Virtual Assistant Generator (virtual_assistant_generator.zip) that, at its actual version v 1.0, enables the automatic generation of Alexa skills to reply to natural language questions by querying SPARQL endpoints. The operating mechanism of the generator is detailed in Section 5 of the article.

To demonstrate the operating mechanisms of the generator, we create the following Alexa skills as use cases, documented in Section 7 of the paper:

- Wikidata_usecase.zip contains the two versions of the Wikidata Alexa skill to show the possibility to customize the linking mode performed by the generator. While in the dictionary-based WikiSkill we exploit a dictionary to perform the entity and relation linking, in the API-driven WikiSkill, we perform the linking phase by relying on the Wikidata APIs. For each skill, we report 1) the Alexa skill components (back_end.zip that implements the skill logic in Node.js and the interaction_model.js that defines the skill intents); 2) the conf.json that corresponds to the configuration file to generate the Alexa skill by our generator (when applicable); 3) the replies corresponding to the evaluation of the Wikidata skills on the QALD-7 training set;

- DBpedia_usecase.zip contains the DBpedia Alexa skills. They are used to demonstrate the different generator configuration options: users can manually create the generator configuration file or auto-generate them, and use it as-is or manually refine it before generating the Alexa skill. For each DBpedia skill, we report 1) the Alexa skills components (back_end.zip that implements the skill logic in Node.js and the interaction_model.js that defines the skill intents); 2) the conf.json that corresponds to the configuration file to generate the Alexa skill by our generator; 3) its evaluation on the QALD-9 training set;

- usesco_usecase.zip contains 1) the UNESCO Thesaurus Alexa skills component (back_end.zip that implements the skill logic in Node.js and the interaction_model.js that defines the skill intents); 2) the conf.json that corresponds to the configuration file to generate the Alexa skill by our generator;

- wordnet_personal_assistant.zip contains 1) the WordNet Alexa skills component (back_end.zip that implements the skill logic in Node.js and the interaction_model.js that defines the skill intents); 2) the conf.json that corresponds to the configuration file to generate the Alexa skill by our generator;

- warsampo_usecase.zip contains 1) the WarSampo Alexa skills component (back_end.zip that implements the skill logic in Node.js and the interaction_model.js that defines the skill intents); 2) the conf.json that corresponds to the configuration file to generate the Alexa skill by our generator;

- dbtune_usecase.zip contains 1) the DBTune classical Alexa skills component (back_end.zip that implements the skill logic in Node.js and the interaction_model.js that defines the skill intents); 2) the conf.json that corresponds to the configuration file to generate the Alexa skill by our generator;

- hungarian_museum_usecase.zip contains 1) the Hungarian museum Alexa skills component (back_end.zip that implements the skill logic in Node.js and the interaction_model.js that defines the skill intents); 2) the conf.json that corresponds to the configuration file to generate the Alexa skill by our generator;

- mmm_usecase.zip contains 1) the Mapping Manuscript Migrations (MMM) Alexa skills component (back_end.zip that implements the skill logic in Node.js and the interaction_model.js that defines the skill intents); 2) the conf.json that corresponds to the configuration file to generate the Alexa skill by our generator;

- natural_features_usecase.zip contains 1) the Natural Features (part of the Scotland's official statistics) Alexa skills component (back_end.zip that implements the skill logic in Node.js and the interaction_model.js that defines the skill intents); 2) the conf.json that corresponds to the configuration file to generate the Alexa skill by our generator;
