Cross-Scheme Management in VocBench 2.1

Cross-Scheme Management in VocBench 2.1 by Armando Stellato.

From the post:

One of the main features of the forthcoming VB2.1 will be SKOS Cross-Scheme Management

I started drafting some notes about cross-scheme management here: https://art-uniroma2.atlassian.net/wiki/display/OWLART/SKOS+Cross-Scheme+Management

I think it is important to have all the integrity checks related to this aspect clear for humans, and not only have them sealed deep in the code. These notes will help users get acquainted with this feature in advance. Once completed, these will be included also in the manual of VB.

For the moment I’ve only written the introduction, some notes about data integrity and then described the checks carried upon the most dangerous operation: removing a concept from a scheme. Together with the VB development group, we will add more information in the next days. However, if you have some questions about this feature, you may post them here, as usual (or you may use the vocbench user/developer user groups).

A consistent set of operations and integrity checks for cross-scheme are already in place for this 2.1, which will be released in the next days.

VB2.2 will focus on other aspects (multi-project management), while we foresee a second wave of facilities for cross-scheme management (such as mass-move/add/remove actions, fixing utilities, analysis of dangling concepts, corrective actions etc..) for VB2.3

I agree that:

I think it is important to have all the integrity checks related to this aspect clear for humans, and not only have them sealed deep in the code.

But I am less certain that following the integrity checks of SKOS is useful in all mappings between schemes.

If you are interested in such constraints, see Armando’s notes.

Machine Learning based Vocabulary Management Tool – Assessment for the Linked Open Data by Ahsan Morshed and Ritaban Dutta.

Abstract:

Reusing domain vocabularies in the context of developing the knowledge based Linked Open data system is the most important discipline on the web. Many editors are available for developing and managing the vocabularies or Ontologies. However, selecting the most relevant editor is very difficult since each vocabulary construction initiative requires its own budget, time, resources. In this paper a novel unsupervised machine learning based comparative assessment mechanism has been proposed for selecting the most relevant editor. Defined evaluation criterions were functionality, reusability, data storage, complexity, association, maintainability, resilience, reliability, robustness, learnability, availability, flexibility, and visibility. Principal component analysis (PCA) was applied on the feedback data set collected from a survey involving sixty users. Focus was to identify the least correlated features carrying the most independent information variance to optimize the tool selection process. An automatic evaluation method based on Bagging Decision Trees has been used to identify the most suitable editor. Three tools namely Vocbench, TopBraid EVN and Pool Party Thesaurus Manager have been evaluated. Decision tree based analysis recommended the Vocbench and the Pool Party Thesaurus Manager are the better performer than the TopBraid EVN tool with very similar recommendation scores.

With the caveat that sixty (60) users in your organization (the number tested in this study), might reach different results, a useful study of vocabulary software.

More useful for the evaluation criteria to use with vocabulary software than in any absolute guide to the appropriate software.

VocBench

From the webpage:

VocBench is a web-based, multilingual, vocabulary editing and workflow tool developed by FAO. It transforms thesauri, authority lists and glossaries into SKOS/RDF concept schemes for use in a linked data environment. VocBench provides tools and functionalities that facilitate the collaborative editing of multilingual terminology and semantic concept information. It further includes administration and group management features as well as built in workflows for maintenance, validation and quality assurance of the data pool.

Current release is (1.3) but 2.0 is due out “Autumn 2012” as open source GPL license.

Another tool that will be of interest to topic map authors.
