Goal-directed Requirements Acquisition
- SCIENCE OF COMPUTER PROGRAMMING
, 1993
"... Requirements analysis includes a preliminary acquisition step where a global model for the specification of the system and its environment is elaborated. This model, called requirements model, involves concepts that are currently not supported by existing formal specification languages, such as goal ..."

, such as goals to be achieved, agents to be assigned, alternatives to be negotiated, etc. The paper presents an approach to requirements acquisition which is driven by such higher-level concepts. Requirements models are acquired as instances of a conceptual meta-model. The latter can be represented as a graph
Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,
, 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

Fast exact inference with a factored model for natural language parsing.
- In Advances in Neural Information Processing Systems,
, 2003
"... Abstract We present a novel generative model for natural language tree structures in which semantic (lexical dependency) and syntactic (PCFG) structures are scored with separate models. This factorization provides conceptual simplicity, straightforward opportunities for separately improving the com ..."

Web Service Modeling Ontology
- STANDARD (WSMO - STANDARD), WSMO DELIVERABLE D2 VERSION 1.0 WORKING DRAFT 29 JULY 2004. AVAILABLE: HTTP://WWW.WSMO.ORG/2004/D2/V1.0/20040729
"... The potential to achieve dynamic, scalable and cost-effective marketplaces and eCommerce solutions has driven recent research efforts towards so-called Semantic Web Services, that are enriching Web services with machine-processable semantics. To this end, the Web Service Modeling Ontology (WSMO) pro ..."

Database Description with SDM: A Semantic Database Model
- ACM Transactions on Database Systems
, 1981
"... SDM is a high-level semantics-based database description and structuring formalism (database model) for databases. This database model is designed to capture more of the meaning of an application environment than is possible with contemporary database models. An SDM specification describes a databas ..."

Framing as a Theory of Media Effects
- London: Journal of Communication
, 1999
"... Research on framing is characterized by theoretical and empirical vagueness. This is due, in part, to the lack of a commonly shared theoretical model underlying framing research. Conceptual problems translate into operational problems, limit-ing the comparability of instruments and results. In this ..."

Semantic data models
- ACM Computing Surveys
, 1988
"... Semantic data models have emerged from a requirement for more expressive conceptual data models. Current generation data models lack direct support for relationships, data abstraction, inheritance, constraints, unstructured objects, and the dynamic properties of an application. Although the need for ..."

Supervised learning of semantic classes for image annotation and retrieval
- IEEE Transactions on Pattern Analysis and Machine Intelligence
, 2007
"... Abstract—A probabilistic formulation for semantic image annotation and retrieval is proposed. Annotation and retrieval are posed as classification problems where each class is defined as the group of database images labeled with a common semantic label. It is shown that, by establishing this one-to- ..."

In particular, images
Capturing and modeling the process of conceptual change
- Learning and Instruction
, 1994
"... A theoretical framework is outlined in this article that attempts to explain the nature of conceptual change that takes place in the learning of physical science. It is argued that a naive framework theory of physics is established early on in infancy and forms the basis of individuals ’ ontology an ..."

Others are accomplished only when existing beliefs and presuppositions are revised. It is proposed that conceptual change is particularly difficult to achieve and very
Saying what you mean in dialogue: A study in conceptual and semantic co-ordination
- Cognition
, 1987
"... This paper explores how conversants co-ordinate their use and interpretation of language in a restricted context. It revolves around the analysis of the spatial descriptions which emerge during the course of 56 dialogues, elicited in the laboratory using a specially designed computer maze game. Two ..."
