| + | ===== Lab instructions ===== | ||
| + | |||
| + | ==== - Semantic Wikis - Introduction ==== | ||
| + | * Browse the [[http://www.slideshare.net/mtgreaves/tutorial-semantic-wikis-and-applications|slides]] up to the ''**BREAK**'' slide (no.106). | ||
| + | * Read the [[http://semantic-mediawiki.org/wiki/Help:Introduction_to_Semantic_MediaWiki|Introduction]] to the Semantic MediaWiki | ||
| + | ==== - Semantic MediaWiki - Categories ==== | ||
| + | - Log in with your username and password given by the teacher to the [[http://loki.ia.agh.edu.pl/smw|SMW test installation]]. | ||
| + | - Create a page <code>http://loki.ia.agh.edu.pl/smw/index.php/jsi2012/<your-name></code> e.g. <code>http://loki.ia.agh.edu.pl/smw/index.php/jsi2012/wtadrian</code> | ||
| + | - Enter the link to the navigation bar | ||
| + | - If the page doesn't exist (and it shouldn't exist yet ;-) ) click ''edit this page'' \\ {{:pl:dydaktyka:semantic_web:smw-create.png?w300|}} \\ and shortly describe yourself, e.g. <code> | ||
| + | My name is Example student. I am 12 years old. | ||
| + | Currently I study at AGH UST, faculty of electrical engineering. | ||
| + | I belong to group <put your lab group number here>. The other members of my group are: | ||
| + | </code> | ||
| + | - Based on the [[http://semantic-mediawiki.org/wiki/Help:Editing|SMW tutorial]], add the page to the **Student** category. | ||
| + | - 8-) Paste the wiki page source (markup) in the report. | ||
| + | - Create a new page as: <code>http://loki.ia.agh.edu.pl/smw/index.php/AGH-UST/Subjects/subject-name</code> and assign it to the category ''University subject''. | ||
| + | - 8-) Paste the wiki page source (markup) in the report. | ||
| + | |||
| + | ==== - Semantic MediaWiki - Properties ==== | ||
| + | - Based on the [[http://semantic-mediawiki.org/wiki/Help:Properties_and_types|Properties and Types]] section annotate the content of your //Student// page so that it contains the following semantic information about you: | ||
| + | * Name (first + last name) | ||
| + | * Age | ||
| + | * Group (choose one) | ||
| + | * 8-) include the updated wikipage source code (markup) in the report. | ||
| + | - Edit the created page that belong to the //University subject// category so that it contains the following properties: | ||
| + | * lead by | ||
| + | * room | ||
| + | * duration | ||
| + | * 8-) include the updated wikipage source code (markup) in the report. | ||
| + | e.g. | ||
| + | <code> | ||
| + | lead by: [[lead by::prof Ligeza]] | ||
| + | room: [[room::B1 121]] | ||
| + | duration: [[duration::90]] min | ||
| + | </code> | ||
| + | |||
| + | ==== - Semantic MediaWiki - Inline queries ==== | ||
| + | - Read the manual section on [[http://semantic-mediawiki.org/wiki/Help:Inline_queries|Inline queries]] | ||
| + | - Using the **inline queries** add to your page the list of the students that are members of your group | ||
| + | - Format the output of the query as unordered list | ||
| + | - 8-) Put the query in the report. | ||
| + | - Build another query listing the students from your group: | ||
| + | - Display it as a table | ||
| + | - Sort by age, then by the name | ||
| + | - Define a default value which will be displayed if the required field (e.g. age) is empty. | ||
| + | - 8-) Put the query in the report. | ||
| + | |||
| + | |||
| + | |||
| + | ==== - Loki - Introduction ==== | ||
| + | - Go to the [[http://loki.ia.agh.edu.pl/|Loki website]]. | ||
| + | - Read the [[http://loki.ia.agh.edu.pl/about.php|About]] page to get to know the system better. | ||
| + | - With your username and password log in to [[http://loki.ia.agh.edu.pl/lokidev|Loki installation]]. | ||
| + | - Read about the Loki possibilities in [[http://loki.ia.agh.edu.pl/lokidev/start#documentation|Documentation]] section (especially ''pluginapi[1/2]''). | ||
| + | |||
| + | ==== - Loki - Use Cases ==== | ||
| + | Choose and do one of the following two tasks: (they are also described in [[http://loki.ia.agh.edu.pl/lokidev/piw:start|Loki]]) | ||
| + | |||
| + | === - Movie recommendation system === | ||
| + | - Create a page of a movie in the ''movie:'' namespace. Assign it to the ''movie'' category. | ||
| + | - Describe the movie **in english** using semantic annotations, according to an example ''filmy:poszukiwacze_zaginionej_arki'' in polish and an example ''bookstore:book:the_call_of_cthulhu'' in english (use the movie relations and the ''genre'' attribute (and possibly more if you want)). | ||
| + | - Describe shortly one of the actors in the ''person:'' namespace and assign it to the ''actor'' category. | ||
| + | - 8-) Copy the wiki pages sources and paste them into the report. | ||
| + | |||
| + | === - Geographic Wiki === | ||
| + | - Create a page of a city in the ''city:'' namespace. Assign it to the ''city'' category. | ||
| + | - Describe the city **in english** using semantic annotations, according to the example: ''miasta:warszawa''. You can add more semantic relations and attributes than in the examples. | ||
| + | - Describe shortly the country of this city, assign it to the ''country'' category. | ||
| + | - 8-) Copy the wiki pages sources and paste them into the report. | ||
| + | |||
| + | ==== - Loki - Semantic Web Standards ==== | ||
| + | - Create a page for yourself in the ''user'' namespace, assign it to the ''user'' category. | ||
| + | - Read the [[http://loki.ia.agh.edu.pl/lokidev/documentation:pluginapi2#sparql_queries|Plugin API v.2.0]], section on SPARQL. | ||
| + | - On your page, build an example SPARQL query which asks for specific kind of movies or cities (you decide what criteria to use in the query!). | ||
| + | - Observe the results. 8-) Put the query into the report. | ||
| + | - Read the [[http://loki.ia.agh.edu.pl/lokidev/documentation:pluginapi2#rdf_export|Plugin API v.2.0]], section on RDF export. | ||
| + | - Export the page you created about a movie or a city. Analyze the exported file. Find the category, relations and attributes that you entered - how are they represented? | ||
| + | |||
| + | ==== - Loki - Reasoning ==== | ||
| + | In Loki it is possible to embed Prolog code within ''<pl>...</pl>'' tags. Using Prolog code create a set of custom recommendations, e.g.: "Movies, where the leading lady is X and the movie was made before 1940" or "City which is located in a country which is by a sea and is not listed as a member of the EU". | ||
| + | - Read the [[http://loki.ia.agh.edu.pl/lokidev/documentation:pluginapi1|Plugin API v.1.0]], section on Prolog. | ||
| + | - On your **user** page create a section ''My Recommendations'' | ||
| + | - Create a Prolog goal so that the movies interesting for you are found. Optionally, you can define the interesting movies/cities with a Prolog rule and use it directly in the goal. | ||
| + | - If you encounter problems, use the [[http://loki.ia.agh.edu.pl/lokidev/documentation:pluginapi2#debug_functions|debug functionality]] of Loki. | ||
| + | |||
| + | 8-) Put the goal in the report. :!: NOTE: This can give you an extra point. If you don't do this exercise, you don't loose a point. Just a present for the end... ;-) | ||
| + | |||
| + | **NOTE: ** [[http://loki.ia.agh.edu.pl/lokidev/documentation:pluginapi1|Plugin API v.1.0]] and this [[http://cslab.ia.agh.edu.pl/_media/explicite:explicite20100408:mng-kkr-gjn-explicite-semantic-wikis.pdf?id=explicite%3Aexplicite20100408%3Astart&cache=cache|presentation]] may be useful. | ||
