Use the tag system#

Tags allow you to organize your bookmarks and publications easier. In BibSonomy you also can use tags as a keyword for searching and comparing items.



How does the tag system work?#

From your computer or in real life, you probably know the opportunity to store files/documents in folders and subfolders. A file is placed in a specific folder.
The keyword system works in a completely different way. You can add as many tags as you want to a file/publication. That way you can find all files about a specific topic very fast and easily, for you only have to search for the corresponding tag. The advantage of the tag system is the fact that you can combine different tags when searching to achieve precise and specific results. For example, if you're looking for literature about the topic "politics in France", you can search with both tags "politics" AND "France". As a result, you get all articles that deal with both topics.
With this function, BibSonomy makes it easy for you to store, manage and share your literature with others.


TIP: Good tags are short and concise. In addition, we recommend to always use singular words (e.g. use tree instead of trees - or even better: use two keywords: tree AND forest), thus avoiding unnecessary word forms. If you want to use a tag that consists of two words (e.g. Computer Science) you should use PascalCase (e.g. ComputerScience).


Add tags to bookmarks/publications#

You can add tags to a bookmark/publication to organize them better and keep the overview.
You can add tags everytime you add a bookmark/publication to your collection (whether you post a new one or you add an existing one). When adding, the system displays recommendations for tags based on your frequently used tags. Also, the system displays the tags of the copied posts, in case you are adding an existing one.



Edit tags on bookmarks/publications#

If you already added a bookmark/publication to your collection, it is still possible to edit the entered tags.
There are several ways to edit the tags.
  1. Edit tags via "edit post"
  2. Edit tags via "fast edit"
  3. Edit tags via "edit tags"


Edit tags via "edit post"#

Click on the black pencil button (edit this bookmark/publication) on the right side of a post. You are directed to a page where you can edit the information about this post, including the tags. When you are done with editing, don't forget to click on the save button on the bottom of the page.

Edit tags via "fast edit"#

Click on the blue pencil button (edit tags) on the left side of a post. A pop-up window appears where you can edit a post's tags directly. You can delete tags by clicking on the X-symbol and add tags by writing them into the textfield, separated by a space character. Click on save to save your changes or on close to discard them.

Edit tags via "edit tags"#

In BibSonomy, you aren't only able to edit the tags of a single post, but also you can edit all your tags that you have used at once. To do so, click on the person symbol in the right main menu and then on edit tags. On the following page, you can edit your tags and concepts.

  • rename/replace tags: Here you can replace a specific tag by another tag. This is useful, if you have used two similar tags that you want to merge into one, for example you can replace augmentedreality by augmentedReality.
  • add subtags to concepts: To add a subtag to a concept, just write the concept's name into the field 'supertag' and the tag you want to add into 'subtag'.
  • delete subtags from concepts: To delete a subtag from a concept, just write the concept's name into the field 'supertag' and the tag you want to delete into 'subtag'.

Navigation via tags#

You can browse through publications and bookmarks in BibSonomy by using tags.

  • Option 1: In order to search for bookmarks/publications with a specific tag, just use the search bar in the right upper corner. Click on the blue arrow next to 'search' and in the dropdown menu, choose tag. Type the tag you want to search for into the search field and click on the magnifying glass symbol or press the enter key.


    The bookmarks/publications tagged with the specific tag will be displayed.
    In the sidebar on the right, you can see additional information about this tag: concepts with this tag, about related tags and similar tags.

  • Option 2: When you click on a tag that is displayed with a post (for example on the home page), you can see all posts of a user with this specific tag. In the sidebar on the right, you can see information about
    • this tag as a tag from all users
    • this tag as a concept from this specific user
    • this tag as a concept from all users
    • related tags
    • the user's concepts
    • the user's tags.

Related tags#

Related tags are those tags which were assigned together to a post. If e.g. a user has tagged a post with java and programming, then those two tags are related.


Similar tags #

Similar tags on the other side are computed by a more complex similarity measure coming from the research on information retrieval (namely cosine similarity in the vector of the popular tags). Similar tags are in many cases synonym tags.

System tags#

System tags are special tags that come with a predefined meaning. At present, BibSonomy offers three types of system tags:

Executable system tags#

Executable system tags are added to a post to execute some special action with that post.
  • for:<groupname>: Tagging a post with for:xygroup will copy that post to the group's collection with the tag replaced by from:YourUserName. Should you change or even delete your post, the copied post of the group will remain unaltered. You must be a member of the group you forward the post to.
  • send:<username>: This tag allows sending a post to the inbox of another BibSonomy user. To use this tag, the receiver must have added you to his friends list or you must be a member of the same group.

Meta system tags#

Meta system tags are used to label your posts. Currently BibSonomy supports the following meta system tags:
  • myown: A post tagged with myown will appear on your CV page.
  • sys:relevantFor:<groupname>: A post with the tag sys:relevantFor:xygroup will appear on the "relevantFor"-page of the xygroup. Thus, this tag has the same effect as selecting xygroup in the "relevant for"-box while editing the post.
  • sys:hidden:<tag>: hides a tag from every user besides yourself.

Search system tags#

Search system tags are not for tagging a post but rather to be used as a filter in search queries. They all have the same syntax: sys:<fieldname><fieldvalue>. For example, searching with sys:author:xyz will only return posts where the author is xyz. BibSonomy supports the following filters:
  • sys:author:<authorname> filters the search range by author.
  • sys:bibtexkey:<bibtexkey> filters the search range by bibtexkey.
  • sys:entrytype:<entrytype> filters the search range by entry type.
  • sys:group:<group> filters the search range by group.
  • sys:not:<tag> excludes entries with the tag <tag>. Here you can also use wildcards, e.g. sys:not:news_* excludes all posts with tags that start with news_.
  • sys:title:<title> filters the search range by title.
  • sys:user:<user> filters the search range by user.
  • sys:year:<year> filters the search by year. Several arguments are possible, e.g.:
    • 2000: all posts from the year 2000
    • 2000-: all posts from the year 2000 or from one of the following years
    • -2000: all posts from the year 2000 or from an earlier year
    • 1990-2000: all posts from the years 1990 to 2000
