Use cases Tagger in Action

Tagger in help of article categorization

Our TAS Tagger solution specializes in tagging (labeling) documents (articles) and providing convenient handling of these tags.

In the user interface, tags and their relations, such as synonyms, co-occurrences, or broader and narrower terms can be configured. This solution increases the efficiency of the document tagging process. And this is extremely important when it is about tagging the articles of a significant participant of the publishing market.

How? The following use case illustrates this.

Implementation of the project

Our client, one of the leading media companies in Hungary required a maintenance system to make the tagging procedure of their articles more effective and more convenient. We developed the given solution so that journalists obtain automated support for the article tagging.

The development was based on three important customer requirements:
1. auto-tagging of articles in the archive, to make previous contents easier to search and find
2. helping journalists in getting tag suggestions to choose from after writing an article
3. built-in user management with multi-level permission system

 

About tags

Tags can be named entities like persons, locations and organizations, or also keyphrases or even Machine Learning based tags.

How to manage the tags
There are several ways to manage the extracted tags. You can create a relationship between them, organize them in groups, or even create a stop list.

Relations
the following relations can be created between tags:
– synonyms, eg. Football – Soccer
– co-occurrences, eg. Anfield – Liverpool
– narrower and broader terms, eg. Motorcycles – Vehicles
The connections appear at the tag suggestions to the journalists, or in automated mode it can be configured to set all the synonyms as tags for example.

Tag categories
You can create categories to group your tags. For example tags related to Sales can be added to the certain category.

Stoplists
Stoplist can be set in the form of regular expressions for the tags. If the article contains this expression then the tag won’t be suggested. For example you can set that if an article contains ‘rain check’ then the tag ‘weather’ won’t appear.

 

Getting insight of tags

Searching between tags
It is possible to search amongst the tags. Users can search based on character matching or filter the list by status and categories.

Visualization of tags
Graph view helps the user to analyze the connection chain between tags.

A multilevel permission system has been set up so tasks can only be done by users who has appropriate rights to do them.

Permissions levels:
Reader: Readers can only browse between the tags, but they can’t edit anything
Editors: They can manage the tags
Admin: They are allowed to manage both of the tags and the categories
Admins can manage the tags and also the tag categories
These permissions can be set in the Manage Users menu.
