1 Adaptive Hypermedia and The Semantic Web Socrates course UPB Romania, Course 5 Dr. Alexandra Cristea

2 MOT new version Many evaluations have been made with the old MOT –(see papers on evaluation at: paper_chrono.html) This resulted in a new version, as follows

3 MOT system components 1.An interface for creation of contenthttp://prolearn.dcs.warwick.ac.uk/MOT/ –Creates Conceptmaps and Lessons 2.An interface to upload adaptive strategies t.html –Adaptive strategies are created as text documents in the latest version (the old interface is incompatible)

4 Changes Look and feel Naming Click distance Confirmation for deletes. Uploading of files other than in text (text, HTML, XML) format (e.g., pictures or videos, slides)

5 Naming The LAOS naming conventions are respected more carefully a clear separation is made between the namemap denoting an instance, and the namemodel denoting the schema concept mapsAs all maps (domain or goal and constraints) are built on the concept model paradigm, they are all concept maps as well

6 1. Content creation in MOT Domain Concept maps: –Are called as in LAOS, domain maps –They still keep the name Concept maps for backward compatibility – they have the same structure of concepts with attributes –Represent the domain model (e.g., of the course) –Book-like hierarchical structures –Contain the links to the actual resources (via attributes) –Allow also non-hierarchical links (relatedness links) –Order of concepts or attributes of (almost) no importance

7 1. Content creation in MOT Goal maps: –Are the Goal and constraints maps from LAOS –The previous name, Lessons, also appears, for backward compatibility –They are obviously also Concept maps (with attributes) –Represent the goal and constraints model e.g., represent the pedagogical view on the course –A filtered (ordered, weighted and labeled) version of the domain maps, with pointers to the original content

8 1. Content creation in MOT: Domain maps

9 author username Access to Goal&C maps Access to Domain maps

10 Authors Domain maps Others

11 MOT Domain map Consists of a hierarchy of concepts and their attributes

12 Domain map name Current concept attributes of the currentconcept Concept hierarchy

13 Concept attributes in the Domain (Concept) map Should contain ONLY domain-related content So: no prerequisites, no pedagogic information

14 Domain attribute creation Current domain concept Domainconceptattribute

15 Uploading other files/content

16 Editing a domain attribute text input window in the left hand panel cut& paste any type of text you wish, –including (X)HTML/ XML –including (X)HTML/ XML !! Condition: you are the author of this domain map.

17 Adding more attributes Adding children concepts AddingRelatednessrelations

18 1. Content creation in MOT: Goal maps* Represent the Goal and Constraint maps (thus instances) of the model with the same name in the LAOS model: goal and constraints model They still keep the name lessons for backward compatibility, and also because MOT is primarily aimed at the educational domain (unlike the LAOS model, which is more generic) –E.g., lessons represent the pedagogical view on the course Concept maps (with attributes) A filtered (ordered, weighted and labeled) version of the domain maps, with pointers to the original content –The order is interpreted as order in which the contents (concepts) should be seen –The labels give qualitative information about the contents –The weights give quantitative information about the contents –Weights and labels are only allowed for groups of concepts connected with an OR, to inform about the comparative desirability of the list of concepts. (if concepts are connected with an AND, they should be interpreted as equally desirable)

19 Authors Goal maps Others

20 Orderingoflessons Weights of sublesson Labels of sublesson

21 GroupofSub-lessons Groupalternatives

22 Changing sub-lesson order

23 Changing weights & labels for sublessons

24 Note: The meaning of the weights & labels is given by the adaptation strategy!

25 Bugs & known problems remaining in the new MOT tagsIf you use html or other tags with MOT, then the lesson view might behave irregularly (because the teacher view truncates the text). The solution is NOT to have html tags in the first 30 characters of the text (or to close them within the first 30 chars).

26 Any questions?
