“…Conceptually, particle shape is the pattern of all points on the boundary of a particle [25,28,34,40,43,55]. Thus, it includes every aspect of external morphology of the particle.…”

“…These descriptions can be used to express an expectation for the behavior of powders and/or particles, for example, for the flow behavior of a powder or the vulnerability of particles to breakage or attrition during processing. A quantitative description of particle shape can be done in many ways [22,25,28,34,40,41,43,50]. In the general practice of industrial powders, one is faced with the problem that the shape descriptor has a statistical distribution and that there may be different particle shapes present.…”

“…2.8 [25,26,30,43,47,48]. For example, A 0 represents the mean radius, A 2 the elongation, A 3 the "triangularity,'' etc., whereas the ratio A 0 /A k represents the bulkiness of a particle.…”

Only for spheres, the size of a particle can be represented by a single parameter, being e.g., its diameter. For the description of a particle of any other shape more parameters are required. Many different descriptors exist. They can be directly related to visual or microscopic measurement, such as length or breadth, or they are based on the concept of equivalent sphere, yielding the diameter of a sphere that shows the same behavior as the particle or group of particles under consideration. Measurement of particle size by different principles may lead to different results for the same group of non-spherical particles. Examples of equivalent sphere diameters are equivalent sieve (or near-mesh) diameter, Stokes' diameter and volume diameter. Usually, the particles in a particulate product do not have the same size but a distribution of sizes. Here too, there are different possibilities for quantitative description. One example is a size distribution, based on number, volume or mass of the particles. Other possibilities are a mean size, a single or a small number of descriptors in the middle or at either side of the distribution, or parameters of a model-distribution. The choice of descriptors for particle size and size distribution should be made such that they give the best discrimination for the quality of the particulate product with respect to given properties or for characterization of a production process. If these properties also depend on particle shape, shape and shape distribution should be characterized in addition to size. This can be done in qualitative terms, such as fibers or flakes, or in quantitative terms, such as elongation, roundness, angularity, surface rugosity, percentages of given model shapes, or fractal dimension. Finally, the porosity of particles may play a role in their behavior. This chapter describes some of the many possibilities that exist.

The internet contains vast amounts of text-based information across various domains, such as commercial documents, medical records, scientific research, engineering tests, and events affecting urban and natural environments. Extracting knowledge from these texts requires a deep understanding of natural language nuances and accurately representing content while preserving essential information. This process enables effective knowledge extraction, inference, and discovery. This paper proposes a critical study of state-of-the-art contributions exploring the complexities and emerging trends in representing, querying, and analysing content extracted from textual data. This study’s hypothesis states that graph-based representations can be particularly effective when annotated with sophisticated querying and analytics techniques. This hypothesis is discussed through the lenses of contributions in linguistics, natural language processing, graph theory, databases, and artificial intelligence.
