American Physical Society Taxonomy – Case Study

Joseph A Busch

Taxonomy Strategies has been working with the American Physical Society (APS) to develop a new faceted classification scheme.

The proposed scheme includes several discrete sets of categories called facets whose values can be combined to express concepts such as existing Physics and Astronomy Classification Scheme (PACS) codes, as well as new concepts that have not yet emerged, or have been difficult to express with the existing PACS.

PACS codes formed a single-hierarchy classification scheme, designed to assign the “one best” category that an item will be classified under. Classification schemes come from the need to physically locate objects in one dimension, for example in a library where a book will be shelved in one and only one location, among an ordered set of other books. Traditional journal tables of contents similarly place each article in a given issue in a specific location among an ordered set of other articles, certainly a necessary constraint with paper journals and still useful online as a comfortable and familiar context for readers.

However, the real world of concepts is multi-dimensional. In collapsing to one dimension, a classification scheme makes essentially arbitrary choices that have the effect of placing some related items close together while leaving other related items in very distant bins. It also has the effect of repeating the terms associated with the last dimension in many different contexts, leading to an appearance of significant redundancy and complexity in locating terms.

A faceted taxonomy attempts to identify each stand-alone concept through the term or terms commonly associated with it, and have it mean the same thing whenever used. Hierarchy in a taxonomy is useful to group related terms together; however the intention is not to attempt to identify an item such as an article or book by a single concept, but rather to assign multiple concepts to represent the meaning. In that way, related items can be closely associated along multiple dimensions corresponding to each assigned concept. Where previously a single PACS code was used to indicate the research area, now two, three, or more of the new concepts may be needed (although often a single new concept will be sufficient). This requires a different mindset and approach in applying the new taxonomy to the way APS has been accustomed to working with PACS; however it also enables significant new capabilities for publishing and working with all types of content including articles, papers and websites.

To build and maintain the faceted taxonomy, APS has acquired the PoolParty taxonomy management tool. PoolParty will enable APS editorial staff to create, retrieve, update and delete taxonomy term records. The tool will support the various thesaurus, knowledge organization system and ontology standards for concepts, relationships, alternate terms etc. It will also provide methods for:

  • Associating taxonomy terms with content items, and storing that association in a content index record.
  • Automated indexing to suggest taxonomy terms that should be associated with content items, and text mining to suggest terms to potentially be added to the taxonomy.
  • Integrating taxonomy term look-up, browse and navigation in a selection user interface that, for example, authors and the general public could use.
  • Implementing a feedback user interface allowing authors and the general public to suggest terms, record the source of the suggestion, and inform the user on the disposition of their suggestion.

Arthur Smith, project manager for the new APS taxonomy notes “PoolParty allows our subject matter experts to immediately visualize the layout of the taxonomy, to add new concepts, suggest alternatives, and to map out the relationships and mappings to other concept schemes that we need. While our project is still in an early stage, the software tool is already proving very useful.”

Bruno Eugster: ‘How to bring already pre-filtered information to the employee’s desk’

0adf38aa6.11669486,3In recent years, PoolParty team has not only worked on the major release PoolParty 4. It also developed a network of experts as its partner organizations, which deliver services for system integration (e.g. SharePoint, FirstSpirit, IntraFind etc.), taxonomy and thesaurus management, and to develop infrastructure for the corporate semantic web. DTI AG is one of those partners which are acting globally as an interface between PoolParty team and the customers. Andreas Blumauer talked with Bruno Eugster, CEO at DTI AG, based in Switzerland.

Blumauer: How do semantic technologies fit into your overall strategy, do you believe they are ‘the next big thing’?

Eugster: DTI AG focuses on projects to improve information access and search, where semantic technologies play an ever important role. In this respect, semantic technologies are one of the next “big things”. Only if computers will understand crawled content, as well as the needs of the information seeker, the user will be able to get the right information in time. This is the key challenge which semantic technology will help to meet.

Blumauer: Which kind of projects in the field of semantic technologies do you mainly support? What are the business cases in such projects?

Eugster: Everywhere where information workers drive customer’s business, semantic technologies are of great help to get precise hits in time. This is the case for DTI’s projects in the sectors of enterprise search, knowledge management, eDiscovery, legal investigations as well as in government, pharma, finance, and insurance industry.

Blumauer: How do your customers benefit from PoolParty technologies? Why did you decide to develop a partnership with Semantic Web Company?

Eugster: In our days, where loads of information dislocated in countless data silos, it’s enormously important to bring already pre-filtered information to the employee’s desk. As each employee has it’s own requirements to given information – depending on his role and job. PoolParty allows to enrich the information with these contexts. At DTI AG,  we have found a dynamic and innovative technology partner with PoolParty, to achieve customer demands in information access and search.

Bruno Eugster is founder of DTI AG which is an independent solution provider in the field of intelligent information search and retrieval. Their target markets are media, financial, life sciences and government.

I-SEMANTICS 2013: Kai Holzweissig about Daimler’s Linked Data Projects

“Product development is an information intensive process, which relies heavily on the division of labor. Thus, product development is not only of high cognitive, but also of high social complexity. Employees in product development possess different “thought worlds” of the product, its components and its development process, that is, they see the product differently. These different “thought worlds” cause communication – and consequently collaboration, which is the topmost success factor in product development – to break down.”

At this years I-Semantics Kai Holzweissig describes the use of controlled vocabularies and product development process reference models at Daimler. The use of controlled vocabulary and the corresponding process reference model as a “discursive anchor” gives employees at Daimler a toolset to harmonize their “thought worlds”. This can result in higher efficiency and effectiveness in product development by fostering inter-departmental collaboration.

About Dr. Kai Holzweissig

He has an educational background in Informatics (PhD) and Cognitive Science (MSc). During his time at University he was awarded scholarships from SIEMENS AG and the Friedrich Naumann Foundation for Freedom. From 2007 to 2011 Kai worked at the Project Management Office at Daimler Trucks. Since 2011 he works for the Chief Technology Officer (CTO) at Daimler’s central IT department. Kai’s technical interests include: Contextual Informatics, Interaction Design, Social Software Theory and Linked Data. Kai is a lecturer for Interactive Systems at Reutlingen University.
