cosine: In a right triangle, the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse.
For other angles, the values of the trigonometric functions are usually found from a set of tables or a scientific calculator. For the limiting values of 0° and 90°, the length of one side of the triangle approaches zero while the other approaches that of the hypotenuse, resulting in the...
The word-sentence matrix generator generates an mXn matrix comprising the m words reflecting the calculated weight and the 'n' sentences. The document summarizer comprises an NMF part(141), a similarity calculator(142), and a sentence selector(143). 展开 ...
In a right triangle, the cosine of an angle is found by dividing the length of the adjacent side by the hypothenuse. If the angle is not acute, use the unit circle and similarity of triangles. What is the definition of the cosine of an angle?

To keep things simple, I've indexed two vectors - [0, 1] and [0, -1]. To my understanding similarity score is simply cosine value for the angle between vectors (also I've used online similarity calculator and my own written function to compare). I saw the actual function in...
