By Noureddine Mouaddib, Guillaume Raschia (auth.), Yahiko Kambayashi, Dik-Lun Lee, Ee-peng Lim, Mukesh Mohania, Yoshifumi Masunaga (eds.)

This publication offers the completely refereed joint post-proceedings of 3 workshops held throughout the seventeenth overseas convention on Conceptual Modeling, ER '98, in Singapore in November 1998. The 50 revised papers offered have undergone rounds of reviewing and revision. The ebook is split in sections on wisdom discovery, info mining, facts and internet warehousing, multidimensional databases, information warehouse layout, caching, information dissemination, replication, cellular networks, cellular structures, monitoring and tracking, collaborative paintings aid, temporal info modelling, relocating items and spatial indexing, spatio-temporal databases, and video database contents.

Methodologies for Intelligent Systems: 6th International Symposium, ISMIS '91 Charlotte, N. C., USA, October 16–19, 1991 Proceedings

This quantity comprises the papers chosen for presentation on the 6th overseas Symposium on Methodol- ogies for clever structures held in Charlotte, North Carolina, in October 1991. The symposium was once hosted by means of UNC-Charlotte and backed through IBM-Charlotte, ORNL/CESAR and UNC-Charlotte. The papers talk about issues within the following significant parts: - Approximate reasoning, - professional platforms, - clever databases, - wisdom illustration, - studying and adaptive structures, - good judgment for man made intelligence.

Example text

The size of the sample is determined based on the acceptable degree of error, and the acceptable probability that this degree of error will be exceeded. The formula for calculating the sample size (Step 1) is discussed in Section 3. Step 2: Assign Representations to All Attribute Groups. Each attribute is assigned a representation based on the analysis of its data type, length of the attribute, and values. The representations of attributes are then used to determine the representations of attribute groups.

These problems include: 1) the identification of the measurement scale of an attribute group, and 2) the need for more information than just the measurement scales to determine the appropriate correlation test. First, to identify the appropriate correlation test, the measurement scales of the attribute groups must be known. For example, one of the correlation tests for interval measurement scales, such as the coefficient of determination should be used to measure the correlation of an attribute group pair with interval measurement scales.
