We derive from first principles the basic equations for a few of the basic hidden-Markov-model word taggers as well as equations for other models which may be novel (the descriptions in previous papers being too spare to be sure). We give performance results for all of the models. The results from our best model (96.45% on an unused test sample from the Brown corpus with 181 distinct tags) is o...

A free semigroup with involution (FSI) is essentially the set of words over a given alphabet plus an operator which reverses words. The paper introduces equations in FSI and show that they are the right objects to deal with when studying the complexity of equations in free groups. On these lines, we generalize to FSI several results valid for word equations, like the overlapping lemma, the 2O(|...

leadership style and organizational climate are considered as a substructure framework in successful performance of knowledge management. the purpose of this research is investigating both the effect of leadership style and organizational climate on knowledge management and the moderate role of organization structure and social interaction in affecting leadership style and organizational climat...

We present evidence of a secondary school teacher’s Knowledge Mathematics Teaching when she teaches linear equations in word problem setting. focus on analyzing the examples and mathematics support that provides her students with during two classes. When faced contingencies, takes decisions whereby adapts or creates emerging action plans order to enrich help overcome their difficulties learn eq...

the numerical investigation of computing the rate of radiated solar-energy requires equations as a function of solar-time according to the radiation angle of the sun (β) in the latitude 37°n and the shape. this paper implements the lagrange interpolation to obtain the equations of normal diagram of elements based on data obtained from surveying. also the method of hann-window equation used to e...

Thank you for giving place to articles on word problems [1, 2]. I am concerned with word problems very much and would like to say something about them also. First of all, in my opinion, any discussion should include a definition of the subject and in such situations it is better to keep as close as possible to the exact meaning of the words. I suggest that a non-word problem is a problem, which...
