A category is the topic you wish to organise your trail under or the topic of interest. Some examples would include Horse Racing, Fishing, Comics, Politics, Rugby, Soccer etc. The examples used in this guide are created using the category "Wine".
|
|
1.1 New Category
To create a new category, you need to do a general search for web pages about that category. Ideally these pages should have a number of words and phrases that would be particular to that category. To create a wine category, for example, go to a web page about wine. This page should show Trailblazer the words and phrases which typically occur on a page about wine. These might include the regions wines come from and the types of grapes.
|
|
 |
|
Once you have found a suitable page, create the category by selecting "Category>New" in the Trailblazer toolbar as shown.
Next, add the name of your new category, in this case "wine", and select ok.
|
|
|
Trailblazer will now train the category using the current page. This gives Trailblazer a base vocabulary with which to recognise that a page belongs to a certain category. Trailblazer will not allow you to add a new category without training on at least one page. Once you click ok after entering your category name, you will be asked if it is ok to train the category on the current page.
Only select ok if the current page contains words relating to the new category you just created. Training the category "Wine" on a page dedicated to horse racing for instance will only prevent Trailblazer from being able to correctly categorise a page dedicated to wine, no matter what further training you do.
Usually a category will need to be trained on more than one category, to properly be able to categorise similar pages. Further training of a category is discussed in the next section.
|
|
|
To enable Trailblazer to correctly categorise pages to specific categories, it is important to train it on many pages with relevant content . If during your browsing you come across a new page with content specific to your category, you should train your Trailblazer category with the page. Pages that contain words that are specific to that category work the best. In the wine category for instance, any site that is specifically about wine is good to train on, but a page that contains lists of grape varieties or wine regions would work best.
|
|
|
Train Trailblazer on the page by selecting "Category>Train" on the Trailblazer toolbar, as shown.
Then select "ok" on the pop up box
|
|
 |
|
|
Export trail can be used for two puproses. The first is for collaborative sharing
of your trails. If you have created an extensive trail about wine, you may want
to share this trail with a friend. At a later stage you may wish to uninstall Trailblazer.
By exporting your trails you have created a backup which can be later imported into
Trailblazer when it is installed again.
|
|
|
Import Trail can be used to import a trail of information previously created for
a category. This trail may have been shared with you by another user or you may
have backed up the trail at a time in the past.
|
|
|
Click on "Category>Import Trail". From here select the location of the file you
wish to import. Click ok and the file will be added to trailblazer.
|

Named Entities are words relevant to a specific category. They are the words that Trailblazer will find and highlight on a page that has been categorised as that specific category. Trailblazer will only find named entities that have been added by the user. Once you have added a named entity on one Web page however, Trailblazer will find that entity on any other page that has been categorised as belonging to the same category.
|
|
|
To add a named entity to a category simply:
- Highlight the word on the page.
- Select "Entity>New Entity" on the Trailblazer toolbar.
- In the popup box, shown in Figure 6, check that you are adding the right "Entity" to the right "Category".
- If everything is alright, select "ok"
By clicking on "Find Entities" you will now see that the entity you just added is
highlighted on the page. Click on this highlighted entity and a bookmark will appear
in the display box at the bottom of the browser.
In the example shown we see that the word highlighted "Syrah" is actually an "Alias"
of the existing entity "Sirah". This means that both words mean the same thing within
this category. In this case, instead of adding a new entity for "Syrah", we can
add it as an "Alias" of "Sirah". To do this simply:
- Select "Sirah" in the drop down menu of existing entities on the left hand side of the popup box.
- Tick the "Alias?" check box.
- Then select "ok".
|
|
|
Deleting an entity involves removing that word from a category, and that category only. That entity will no longer be found during annotation and any bookmarks or notes associated with that entity will also be deleted.
To delete an existing named entity from your category simply:
- Select "Entity>Delete Entity" on the Trailblazer toolbar.
- In the popup box, select the "Entity" you wish
to delete from the appropriate "Category".
- Then select "ok"
|
|
|
The Alias of an entity, is a word that either means or references the same thing. You can delete an "Alias" without effecting the entity itself, so all bookmarks and notes associated with that Entity and the Alias are still attached to the Entity.
To delete an Alias of an Entity from your category simply:
- Select "Entity>Delete Alias of Entity" on the Trailblazer toolbar.
- In the popup box, select the "Entity" you wish
to delete from the appropriate "Category".
- Then select "ok"
|
|
|
By pressing the "Find Entites" button, Trailblazer highlights any entities it knows about for the
particular cateogry it classified the page to. If you have previously added an entity for the category wine, then
whenever Trailblazer categories a different page to wine and the entity is displayed on the page then "Find Entites"
will highlight the entity.
Clicking on a highlighted named entity displays any
bookmarks, notes or wiki links for this entity.

A bookmark is a url to a piece of information the user considers important. They
may wish to maintain a bookmark to a website which describes their favourite wine
or they may wish to bookmark an online store which sells their favourite chardonnay.
|
|
|
|
|
Often you may change your mind about the title of your bookmark. Using this functionality
it is possible to edit the bookmark's description.
|
|
|
Why not add a note to an entity? It could be a short as an email address, the
full text for an abbreviated concept or a definition for an entity. The text below
will show you how to add a note and delete it.

A wiki is a website or an online resource which allows
the user to edit or add to its content. A popular wiki is
the collaborative online encyclopedia Wikpedia
http://en.wikipedia.org/wiki
It is useful to associate a wiki page to an entity using
trailblazer. If you are reading about the shiraz grape you
might want to record a thought or an idea. By adding a wiki
page to the shiraz entity, you can store all your comments
and thoughts about shiraz on the wiki page. Not only is this
wiki page now available in your display box at the bottom of
the screen every time you click on shiraz but other users
can read your wiki page and add their own comments about
shiraz.
Remember, you cannot add a wiki page without first adding
a wiki site. You can tell Trailblazer which wiki's you wish
to use by adding their urls. To read further on how to add
wikis to Trailblazer read

This functionality deletes the reference to the Wiki Page for an entity. This however does not delete the page from the wiki. Deleting wiki pages is only allowed in some wiki's and the method used can be different.
