Summary
We developed a new visualization system to evaluate Medical Subject Headings (MeSH) indexing. This tool compares automatic Medical Text Indexer (MTI) results against human indexers using graphical displays.
Area of Science:
- Biomedical Informatics
- Medical Information Science
- Information Visualization
Background:
- MEDLINE database indexing is crucial for biomedical literature retrieval.
- Evaluating the accuracy of automated indexing systems like the Medical Text Indexer (MTI) is essential.
- Existing evaluation methods may lack intuitive visual representations of complex indexing structures.
Purpose of the Study:
- To introduce an interactive visualization system for assessing MEDLINE indexing results.
- To graphically represent indexing similarity against the Medical Subject Headings (MeSH) hierarchy.
- To enable comparison between the Medical Text Indexer (MTI) and human indexers.
Main Methods:
- Development of a novel interactive visualization system.
- Utilizing a radial-tree layout to display the MeSH structure.
- Employing 2D color coding and a 3D height field for similarity measurements.
Main Results:
- The system provides a visual method for evaluating indexing performance.
- Indexing similarity is clearly depicted through color and height variations.
- Facilitates direct comparison of MTI performance against human indexing standards.
Conclusions:
- The developed visualization system offers an effective tool for evaluating automated indexing quality.
- Graphical representation enhances the understanding of indexing similarities and discrepancies.
- This approach aids in the assessment and improvement of biomedical text indexing systems.

01:20Mesh Analysis
Mesh analysis is a valuable method for simplifying circuit analysis using mesh currents as key circuit variables. Unlike nodal analysis, which focuses on determining unknown voltages, mesh analysis applies Kirchhoff's voltage law (KVL) to find unknown currents within a circuit. This method is particularly convenient in reducing the number of simultaneous equations that need to be solved.
A fundamental concept in mesh analysis is the definition of meshes and mesh currents. A mesh is a closed...

01:12Modeling and Similitude
Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...
01:10Mesh Analysis with Current Sources
Mesh analysis becomes simpler when analyzing circuits with current sources, whether independent or dependent. The presence of current sources reduces the number of equations required for analysis. Two cases illustrate this:
Current Source in One Mesh: The analysis process is straightforward when a current source is found in only one mesh within the circuit. Mesh currents are assigned as usual, with the mesh containing the current source excluded from the analysis. Kirchhoff's voltage law (KVL)...

01:20Divergence Theorem in 3D Space
In vector calculus, flux measures the total flow of a vector field through a surface. For a closed surface in three-dimensional space, this means measuring how much of the field passes outward through every point on the boundary. Directly calculating this flux can be difficult when the surface has a complicated or irregular shape. The Divergence Theorem provides a powerful alternative by relating surface flux to behavior inside the enclosed region.The Divergence Theorem states that the outward...
01:06Collisions in Multiple Dimensions: Problem Solving
In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

01:05Collisions in Multiple Dimensions: Introduction
It is far more common for collisions to occur in two dimensions; that is, the initial velocity vectors are neither parallel nor antiparallel to each other. Let's see what complications arise from this. The first idea is that momentum is a vector. Like all vectors, it can be expressed as a sum of perpendicular components (usually, though not always, an x-component and a y-component, and a z-component if necessary). Thus, when the statement of conservation of momentum is written for a problem,...
