This e-book develops concise and finished recommendations for extracting measure info from average language texts. First, an outline of the ParseTalk details extraction method is given. Then, from the evaluate of correct linguistic literature, the writer derives designated different types of typical language measure expressions and proposes knowledge-intensive algorithms to deal with their analyses within the ParseTalk method. furthermore, for inferencing the writer generalizes from famous constraint propagation mechanisms. The suggestions and techniques built are utilized to textual content domain names from clinical analysis and data know-how magazines. the realization of the ebook offers an integration of all 3 degrees of realizing leading to extra complex and extra effective info extraction mechanisms.

The Degree Subhierarchy — An Excerpt Continuous and Discrete Scales. Furthermore, scales can be categorized according to whether their degrees vary continuously or discretely. A typical example for the latter are natural numbers or military ranks, such as private, sergeant, lieutenant. Continuous variation can be found for properties like weight or height.

A standard graphical notation for description logics has been established in order to provide a more convenient view of the knowledge base. 3) are depicted in this style in Fig. 6. 6. , Input-Device to Device). , has-Input-Channel) are indicated by arrows with tags which describe the number restriction as an interval (here: [1,NIL]; NIL denotes ∞). The tags are named and depicted graphically by a circled square. Instances are rectangles with thin edges.

The best thing would be US letter size. Hence, I do not subscribe to the view held by Cruse (1986) who distinguishes between several types of lexical entries that relate to scales with different structures. Rather, I conceive that scales themselves impose restric- 36 3. Lexical Semantics of Degree Expressions tions on the applicability of degree expressions. Thus, information about the type of a scale should be entered into the world knowledge description and not into the lexicon. In the further course of this book I will restrict myself to continuous scales.
