Some Properties of the Attribute Value Trees Used for Linguistic Knowledge Representation
نویسنده
چکیده
AVT (Attribute Value Tree) can be considered a generalization of AVM (Attribute Value Matrix) used in many Feature Structured Unification grammars (FSUG). In this paper we give some properties of the AVT like: paths in an AVT, exclusive combinations in an AVT, logical interpretation of an AVT, well formed AVT, the equivalence of the AVTs, the ordered AVTs, the AVTs intersection, the AVTs difference, the AVT normalization, the AVTs unfiability and the AVTs unification. Using these properties, the AVTs can be used more easily in the morphological description of a language, the morphological analysis of a text, the text annotation, the grammar analysis, the generation process and even in an automatic translation

A New Algorithm for Optimization of Fuzzy Decision Tree in Data Mining
Decision-tree algorithms provide one of the most popular methodologies for symbolic knowledge acquisition. The resulting knowledge, a symbolic decision tree along with a simple inference mechanism, has been praised for comprehensibility. The most comprehensible decision trees have been designed for perfect symbolic data. Classical crisp decision trees (DT) are widely applied to classification t...

This paper gives an outline about most important features of GRAALAN (Grammar Abstract Language) used for linguistic knowledge description. GRAALAN is an implementation of theoretical concepts of GDGF (Generative Dependency Grammars with Features) and AVT (Attribute Value Trees). GDGF is based on dependency trees (DT) and a generative process. GDG eliminates some issues of Dependency Grammars D...
متن کاملArithmetic Aggregation Operators for Interval-valued Intuitionistic Linguistic Variables and Application to Multi-attribute Group Decision Making
The intuitionistic linguistic set (ILS) is an extension of linguisitc variable. To overcome the drawback of using single real number to represent membership degree and non-membership degree for ILS, the concept of interval-valued intuitionistic linguistic set (IVILS) is introduced through representing the membership degree and non-membership degree with intervals for ILS in this paper. The oper...
