| - | ===== 08.03.04 ===== | ||
| - | |||
| - | |||
| - | |||
| - | ===== 080401 ===== | ||
| - | * Porównanie API Jeny i RDF SWI Prologu | ||
| - | * jak zapisywać //reguły// w Jenie? | ||
| - | * jaka jest różnica w sile ekspresji reguł jeny i Prologu? | ||
| - | * opis dostarczonych z Jeną mechanizmów wnioskujących (reasoners) | ||

| - | ===== 080415 ===== | ||
| - | * przykład [[hekate:hekate_case_thermostat|termostatu]] w RDF w Jenie | ||

| - | |||
| - | ====== Projekt ====== | ||
| - | * "implementacja" jsr94 w prologu | ||
| - | * możliwość/sensowność jess/prolog | ||
| - | |||
| - | Ponieważ Jess można używać jedynie przez 30 dni, wykorzystuję do integracji framework Jena. | ||
| - | |||
| - | * Jednym z zalet Jeny jest czytanie/zapisywanie RDF w RDF/XML, N3 oraz N-Triples. Stąd słuszne wydaje się podejście | ||
| - | Prolog <-przedstawienie wiedzy-> RDF <-przedstawienie wiedzy-> Java | ||
| - | |||
| - | * Mały program w Java, który pokazuje relacje pomiędzy tatą (Jan), mamą (Krystyna), córką (Kasia), synem (Jasiu) | ||
| - | |||
| - | Zostały zapisane następujące dane: | ||
| - | corka.addProperty(siostra, syn); | ||
| - | tata.addProperty(ojciec, corka); | ||
| - | tata.addProperty(ojciec, syn); | ||
| - | tata.addProperty(malzonek, mama); | ||
| - | mama.addProperty(malzonek, tata); | ||
| - | Statement statement1 = model.createStatement(syn, dziecko, mama); | ||
| - | Statement statement2 = model.createStatement(syn, dziecko, tata); | ||
| - | Statement statement3 = model.createStatement(corka, dziecko, mama); | ||

| - | <code xml> | ||
| - | <rdf:RDF | ||
| - | xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" | ||
| - | xmlns:j.0="http://purl.org/vocab/relacje/" > | ||

| - | </rdf:RDF> | ||
| - | </code> | ||
| - | Przekazany RDF do Javy daje model z zawartością 9 informacji. | ||
| - | |||
| - | Po zadaniu prostych zapytań | ||
| - | |||
| - | syn.listProperties(dziecko); | ||
| - | corka.listProperties(dziecko); | ||
| - | corka.listProperties(siostra); | ||
| - | otrzymałem: | ||
| - | |||
| - | http://Family/KowalskiJasiu jest dzieckiem | ||
| - | http://Family/KowalskiJan | ||
| - | http://Family/KowalskiKrystyna | ||
| - | http://Family/KowalskiKasia jest dzieckiem | ||
| - | http://Family/KowalskiJan | ||
| - | http://Family/KowalskiKrystyna | ||
| - | http://Family/KowalskiKasia ma rodzenstwo | ||
| - | http://Family/KowalskiJasiu | ||
| - | |||
| - | ==SPARQL== | ||
| - | Zapytania buduje się podobnie jak w języku zapytań SQL z tą różnicą, że podaje się całą trójkę. | ||
| - | Zapytanie SPARQL dla podanego powyżej przykładu może wyglądać tak: | ||
| - | |||
| - | <code> | ||
| - | SELECT ?x ?w ?q | ||
| - | WHERE {?x ?w ?q} | ||
| - | </code> | ||
| - | Oznacza to podgląd całej wiedzy, która jest zawarta w modelu. | ||
| - | |||
| - | Na takie zapytanie uzyskałem taką odpowiedź: | ||
| - | <code> | ||
| - | Jasiu dziecko Jan | ||
| - | Jasiu dziecko Krystyna | ||
| - | Krystyna malzonek Jan | ||
| - | Jan malzonek Krystyna | ||
| - | Jan ojciec Jasiu | ||
| - | Jan ojciec Kasia | ||
| - | Kasia dziecko Jan | ||
| - | Kasia dziecko Krystyna | ||
| - | Kasia siostra Jasiu | ||
| - | </code> | ||
| - | |||
| - | Jak widać są to wszytkie informacje, które zawarłem w modelu. (Dla czytelności zostały usunięte URI, aby odpowiedź nie wygdlądała np. tak http://Family/KowalskiJan) | ||
| - | |||
| - | Znając zasadę tworzenia zapytania, można otrzymać odpowiedź na "skomplikowane" zapytanie. | ||
| - | |||
| - | ==Termostat - RDF== | ||
| - | |||
| - | Aby stworzyć plik RDF reprezentujący model termostatu, najpierw utworzyłem model termostatu wg. reguł. | ||
| - | |||
| - | Aby plik taki został wygenerowany ścieżki do resoure'ów oraz propertis'ów muszą być unikalne stąd musiałem stworzyć dwa Stringi, którymi poprzedzałem każdy z nich. | ||
| - | <code> | ||
| - | static final String resourceUri = "http://Resource/my/"; | ||
| - | static final String propertyUri = "http://Property/my/"; | ||
| - | </code> | ||
| - | |||
| - | |||
| - | Tak zapisałem model w Javie: | ||
| - | <code> | ||
| - | Model model = ModelFactory.createDefaultModel(); | ||
| - | //1 | ||
| - | Resource day = model.createResource(resourceUri+ "Day"); | ||
| - | Resource workday = model.createResource(resourceUri+"Workday"); | ||

| - | day.addProperty(friday, workday); | ||

| - | month.addProperty(may, autumn); | ||

| - | Property businessHours = model.createProperty(propertyUri + "businessHours"); | ||
| - | Property notBusinessHours = model.createProperty(propertyUri + "notBusinessHours"); | ||
| - | operation.addProperty(businessHours, hour); | ||
| - | operation.addProperty(notBusinessHours, hour); | ||
| - | |||
| - | //14 15 16 17 18 | ||
| - | Resource thermostat = model.createResource(resourceUri + "thermostat"); | ||
| - | Resource setting = model.createResource(resourceUri + "setting"); | ||
