Two selfdocument periods where executed: 1) early December setting up a vocabulary for the course of “Semiotiikan Metodologia” (Semiotic methodology) and 2) the tenth of January to continue the editing of the previously made vocabulary. Main results: Positive: The main functions of the Tag Vocabulary work. These functions are: o Adding, changing, deleting, and organising tags o Writing descriptions and saving the added vocabulary o The visual elements are clear, i.e., what to do and what they mean o It also looks like an easy tool to use o The tags added into the vocabulary are presented as suggestions when tagging a content item, o Hierarchical organisation of the tags in the Tag Vocabulary works Problems: The user cannot write alternative tags The tags users defined (free tags) for the content items do not appear in the right side of the Tag Vocabulary editor The added vocabulary do not appear items in the “select vocabulary” drop down list of the form for tagging a content item When using the Tag Vocabulary editor it should Not make the background (the use of the content view) inactive. Other use problems: The loading of the Tag Vocabulary editor was somewhat slow Link descriptions were presented a suggestions when tagging a content item The OK-button in the form of tagging content items keeps being inactive until the user changes something in the title or description The tags are not displayed in the info tab when selecting a content item active There are too many separate parts in the info tab, if there is a lot of information they do not fit into one screen. Suggestion: use less arrows, i.e., more information combined under one arrow (see http://kplab.evtek.fi:8080/wiki/Wiki.jsp?page=M24GeneralImprovements) Table of contents Introduction Product Description ............................................................................... 3 Method Participants .................................................................................................. 3 Context of Product Use in the Test ........................................................................ 3 Results ........................................................................................................................ 4 References ...................................................................................................................... 6 2 Introduction Product Description VM32 release of Tag Vocabulary editor The Tag Vocabulary Editor is an important tool for supporting users possibility to form own conceptualisations of the concepts, knowledge objects etc., and organise them according to the subject matter. The Tag Vocabulary editor allows the users to insert new tags, modify and organise the tags hierarchically. The idea is it to be easy and fast to use to avoid the common problem of current ontology editors that require extensive knowledge on the ontology creation to be useful and usable. The Tag Vocabulary editor is highly integrated allowing the tags of the content items to appear in the Tag Vocabulary and the added tags in the Tag Vocabulary to appear as suggestion when tagging the content items. The basic functionalities of the Tag Vocabulary are the following: Add/Modify vocabulary metadata Add a new term Modify an existing term Delete a term Publish the Vocabulary for use inside a shared space Attach a note to a term (description metadata field of a term/concept) Modify an existing term title The testing process covered the basic functionalities of the tool as well as observing the integration to the content item tagging procedure. It aimed at examine how these functionalities work in individual use. Method Participants One participant tested the Tag Vocabulary editor in a real life situation. The participant was a teacher of the course “Semiotiikan metodologia”. The participant had previous knowledge on the Tag Vocabulary editor. Therefore, the testing aimed at finding out if the functions work and if it works in the manner that was envisioned. The ease of use is somewhat speculative since the participant knew before hand how the tool is supposed to work. The participant also has quite good technological skills and can be said not be “scared” of just trying out things. The documentation followed the self-documentation manner, e.g., the participant wrote down problems, irritations, and positive points when they occurred in the use. Context of Product Use in the Test The above-mentioned functions were used since they reflect the core actions in Tag Vocabulary editor and are also crucial from the perspective of trialogical approach for supporting users conceptual framework creation. Each task was regarded as successfully performed if its completion led to the supposed outcome visible to the participant performing them. 3 The contextual setting was a course at Helsinki University on Semiotic methodology. In the course it would be essential to learn to use different concepts, be able to organise them easily so that it does not disturb the other assigned work on the course. The tagging of content items and organising the concepts is a supporting activity in the course. The idea was that the teacher would make a start by tagging some material, notes etc., and from those terms form a common vocabulary, which the students would then use and evolve further. Participants’ Computing Environment The computer use for the course activities by the participants was: Mac OS X, version 10.5.6, processor 2.4 Ghz Intel Core 2 Duo The browser used for the activities was: Flock, Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.1.18) Gecko/20081107 Firefox/2.0.0.18 Flock/1.2.7 Procedure The protocol followed the self-documentation manner (see Laitakari et al.2003). The participant wrote down, and if necessary took screenshots of the problems encountered as well as noted the positive aspects of the use when completing the tasks what the participant would do to follow her course organisation. The participant also placed preliminary suggestion for improve the tool. Results The following tables summarise the results of the self-documentation. Period: Early December Task/functionality Add a vocabulary Status of completion Succeeded Filling the form for new vocabulary Adding terms/tags Succeeded Organising terms/tags Succeeded Delete term/tag Did not succeed Save the vocabulary Did not succeed Succeeded Observations First looked at tools menu; the Tag Vocabulary editor was not there. Then rightclicked to the background of the content view – Yes hit. Clear Problems the place to add the term did not erase the guiding text, the user had to write on top of text – annoying (has been fixed already) Had to try couple of times the system was a bit slow in reacting to the user inputs e.g., dragging of the terms on top of each other to make “sub-terms”. The trash was still missing (has been fixed already) It seemed to be saved. 4 There was a statement that the saving did succeed. But the Tag Vocabulary content item did not appear in the content view, which would have allowed opening the just created Tag Vocabulary. Opening the Tag Succeeded It was possible to open the Vocabulary again Tag Vocabulary the same way as adding a new one. But it is misleading since the user has to select “add vocabulary” which s/he is not doing when opening the vocabulary s/he just added. Decision: Participant decided not to introduce the Tag Vocabulary editor yet to the students, too many things were still not working properly. In addition, the tags did not appear as suggestion when tagging content items and the already given tags of the content items did not appear in the Tag Vocabulary in the right side (Free tag vocabulary) for using them in the structuring of the added vocabulary as well as there was no way of seeing the given tags of the content items anywhere, i.e., they did not appear in the Info Tab. Positive aspect: the drag and drop is nice and the visual look is pleasant, it does not look like a hard tool to use. Can be seen to lower the thresh hold to use it. Date: 10th of December 2009 Task/functionality Status of completion Open previously Succeeded added vocabulary Managing terms/tags Succeeded Writing description to terms/tags Writing an alternative term/tag Succeeded Saving the changes made Succeeded Changing metadata of the vocabulary Did not succeed No Success Observations After last time figuring out where to open the vocabulary again, it was faster now, still though annoying (the content item Type: Vocabulary should be soon implemented). No problem of adding more tags in the vocabulary, deleting terms/tags and organising them hierarchy. No problem in that - clear. The field to type the Alternative term/tag was not active, i.e., the user could not write there anything There was a pop up stating that the saving succeeded and the changes were visible after closing the vocabulary and opening it again. When opening the vocabulary again the fields of the name and description of the vocabulary are inactive. But when in the Tag Vocabulary editor the user could activate the title of the vocabulary and edit it, but the description that 5 Using the Free term vocabulary (user defined terms) No success Tagging Content items with the tags from the made vocabulary Success Deleting tag/terms Succeeded from Vocabulary – the term does not appear as suggestion Selecting a No success vocabulary when tagging a content item Tagging the content Succeeded item was given to the vocabulary was not in the description text field. Thus there is no way of editing the description after the vocabulary has been created. It was not possible to use the tags/terms that were placed to the content items using the free tag vocabulary. These tags/terms do not appear on the right side of the Tag Vocabulary editor as they should for adding them to the tag hierarchy of the made vocabulary. Thus, the integration seems not to work properly. The tags added in the Tag Vocabulary editor do appear as suggestions when tagging a content item. However, it also provides the link descriptions as suggestions, which should not come for the tagging of content items. The tags/terms that are deleted from the vocabulary are also eliminated for the suggestion list when tagging a content item. If the user wants to select the vocabulary s/he made, it does not appear in the form’s drop down list for selecting what vocabulary to use for the tagging. But the tags are not visible anywhere, e.g., they do not appear in the Info tab. Also it is nor possible to see the previously added tags of the content item the user is tagging in the field for tags (see suggestion for improvements http://kplab.evtek.fi:8080/wiki/Wiki.jsp?page= M24ImprovementsOfTagging) General comments: The loading of the Tag Vocabulary editor is sometimes somewhat slow. It would be good to provide a feedback for the user that the system is active and that the Tag Vocabulary editor is being loaded; The OK button still keeps inactive in the form where the tagging of the content items occurs unless the user changes something on the title, or description; When adding and managing the tags in the Tag Vocabulary editor the background should not become dimmed, it would enhance the use of the Tag Vocabulary editor if the user could in the same time tag the content items and work in the content view. In similar manner that the peer-to-peer chat works; There are too many separate parts in the info tab, if there is a lot of information they do not fit into one screen. Suggestion: use less arrows, i.e., more information combined under one arrow (see http://kplab.evtek.fi:8080/wiki/Wiki.jsp?page=M24GeneralImprovements) Validity – reliability Validity of the test can be seen to be good. Since the functionalities and their expected outcomes where know, going through them and seeing if they work or not, measures 6 well success of the functionalities. The self-documentation manner is well suited to take into account the feelings and ease of use. Reliability can be said to be good in respect to the testing of the functionalities, since these were basic functionalities and it is clearly visible if they work or not. Anyone who has been provided the list of the functions and their expected outcome could do the test. However, in expressing the feelings or ease of use remains subjective and can be generalised only to similar users than the tester and even then with caution.
