ClassificationPlugin

Description

ClassificationPlugin is a taxonomy and folksonomy extension for Foswiki that allows you to manage knowledge assets stored in your wiki. Users can organize their content by filing topics into categories and by adding offhand tags. Classifying content using categories and tags are the key factors to foster sustainable knowledge management. This becomes even more important in a wiki environment where content is created quickly but has to be made available for a longer period of time.

Categories become the backbone spanning all of your content. Content can then be retrieved by browsing categories narrowing down search results interactively in addition to the normal full-text search.

Key features

• Multilevel facet navigation: Wiki content is displayed dynamically by browsing a category tree or by means of interactive tag clouds.

• Managing taxonomies the wiki way: Categories in a taxonomy are first-class wiki citizens that can be created, renamed, managed and reused as easily as normal wiki topics.

• Expressive knowledge models: Categories may form poly-hierarchies where categories can have multiple parent categories. Wiki documents can be filed into multiple categories at the same time.

• Multidimensional classification: A wiki document may participate in multiple taxonomies and folksonomies at the same time. Different facets of a document can be separated in a clean way.

• Reusing and merging taxonomies: A category tree once defined in one web space can be imported into another web space effortless. You are free to chose which part of a tree you want to import. Multiple category trees from a number of web spaces can be merged and reassembled differently in a new web. That way predefined taxonomies can be managed in a centralized way and reused as needed in different webs. Any change to a taxonomy in one place will automatically show up in all webs that imported it.

• Tagging for corporate intranets: While categories establish a predefined vocabulary, tags are a way to assign keywords to wiki content in an ad hoc fashion. This completes category knowledge management in a natural and fruitful way.

• Standardized WikiApplicatons: ClassificationPlugin conforms to the WikiWorkbench application framework that grants for scalable and long-term maintainable WikiApplications.

• Extensibility: ClassificationPlugin serves as a building block for further WikiApplications to be integrated in an overall knowledge management infrastructure. It serves as a middleware for a couple of higher order applications, like blogging, forums and skills management available separately.

• Document types: ClassificationPlugin adds a couple of document types to the standard set that come with the WikiWorkbench. This gives you maximum flexibility in your knowledge management initiative. Further document types can be derived with ease. These will automatically participate in the overall knowledge management framework.

• Facetted Search: ClassificationPlugin integrates well into Foswiki:Extensions/SolrPlugin using tags and categories to drill down into search results.

SIMILARTOPICS

Returns a list of topics that are similar to the current one. Similarity between two topics is a value expressed in percentage, where 100% means that the topics are extremely similar and 0% means that the compared topics aren't corelated at all. The similarity is computed on the base of the categorization and tagging information using a weighted matching coefficient.
