Evaluating collections of XML documents without paying attention to the schema they were written in may give interesting insights about the expected characteristics of a markup language, as well as bout any regularity that may span across vocabularies and languages, and that are more fundamental and frequent than plain content models. In this paper we explore the idea of structural patterns in ...

This paper investigates the perplexity and word error rate performance of two different forms of class model and the respective data-driven algorithms for obtaining automatic word classifications. The computational complexity of the algorithm for the ‘conventional’ two-sided class model is found to be unsuitable for very large vocabularies ( 100k) or large numbers of classes ( 2000). A one-side...

The National Library of Medicine (NLM) and the Agency for Health Care Policy and Research (AHCPR) are sponsoring a test to determine the extent to which a combination of existing health-related terminologies covers vocabulary needed in health information systems. The test vocabularies are the 30 that are fully or partially represented in the 1996 edition of the Unified Medical Language System (...

Approaches for the analysis and specification of business vocabularies and rules are relevant topics in both Business Process Management and Information Systems Development disciplines. However, in common practice of Information Systems Development, the Business modeling activities still are of mostly empiric nature. In this paper, aspects of the approach for semi-automatic extraction of busine...

Because of the benefits of standardization in healthcare data for research, decision support, and quality assessment, much research effort focuses on collection of structured patient data. Many strategies to obtain such data are based on controlled vocabularies to guide data entry in a far more flexible way than a fixed-form approach. Medical controlled vocabularies evolve, but change is diffic...

The need of biomedical vocabularies is well known for various tasks, e.g., supporting structured data entry, decision support and electronic data exchange as well as retrieval and statistical evaluation of the data. Due to a considerable diversity of artifacts like interface terminologies, classifications and thesauri it seems to be reasonable to demand for a massive reduction and, finally, to ...

Modal transition systems (MTSs) and their variants such as Disjunctive MTSs (DMTSs) have been extensively studied as a formalism for partial behaviour model specification. Their semantics is in terms of implementations, which are fully specified behaviour models in the form of Labelled Transition Systems. A natural operation for these models is that of merge, which should yield a partial model ...

The Spatial Information Services Stack Vocabulary Service (SISSVoc) is a Linked Data API for accessing published vocabularies. SISSVoc provides a RESTful interface via a set of URI patterns that are aligned with SKOS. These provide a standard web interface for any vocabulary which uses SKOS classes and properties. The SISSVoc implementation provides web pages for human users, and machine-readab...

Controlled and uncontrolled indexing terminology and metadata may be converted from one to another. Decision criteria are developed that can be used to determine which terms should be assigned when converting vocabularies. Methods are developed for computing the parameters of these systems, as well as means for estimating the parameters when given limited information. These conversion technique...

The Plant Ontology Consortium (POC) (www.plantontology.org) is a collaborative effort among several plant databases and experts in plant systematics, botany and genomics. A primary goal of the POC is to develop simple yet robust and extensible controlled vocabularies that accurately reflect the biology of plant structures and developmental stages. These provide a network of vocabularies linked ...
