In this paper, a well-conditioned collocation method is constructed for solving general p-th order linear differential equations with various types of boundary conditions. Based on a suitable Birkhoff interpolation, we obtain a new set of polynomial basis functions that results in a collocation scheme with two important features: the condition number of the linear system is independent of the n...

Thematic analysis is important for a lot of applications dealing with texts, such as text summarisation or information extraction. But it can be done with a great precision only if it relies on structured knowledge, which is difficult to produce. In this paper, we propose using bootstrapping in order to solve this problem: a first thematic analysis based on a weakly structured source of knowled...

Previous approaches on automatic extraction of lexical similarities have considered as semantic unit of text the word. However, the theoretical perspective of contextual lexical semantics suggests that larger segments of text, specifically non-compositional multiwords, are more appropriate for this role. We experimentally tested the applicability of this notion, applying automatic collocation e...

Nowadays, society needs to understand the Covid-19 virus and improve appropriate attitudes actions, especially Generation Z. The present study aimed investigate adolescents' knowledge, responses, attitudes. This research method was a descriptive case study. Data were collected using free word association test semi-structured interviews. Respondents amounted 400 people with an age range of 17-24...

We propose a discrete collocation method for the boundary integral equations which arise from solving Laplace's equation u = 0. The Laplace's equation is deened on connected regions D in R 3 with a smooth boundary S. The piecewise polynomial interpolation in the parametrization variables along with the collocation method is used, and a numerical integration scheme for collocation integrals is g...

This article investigates the stability of the collocation method for the Radiosity equation. We introduce graded meshes and trial spaces of piecewise poynomials and prove stability for some modified collocation method. Next we show that graded meshes are necessary, even for linear convergence. The generation of triangulations which allow higher order approximations leads to geometrical problem...

This study evaluates the impact of integrating two different collocation segmentations methods in a standard phrase-based statistical machine translation approach. The collocation segmentation techniques are implemented simultaneously in the source and target side. Each resulting collocation segmentation is used to extract translation units. Experiments are reported in the English-to-Spanish Bi...

Collocation and colligation are two closely related concepts associated with the distributional properties of linguistic items in actual language use. Specifically, collocation and colligation refer to the likelihood of co-occurrence of (two or more) lexical items and grammatical categories, respectively. Both terms have been attributed to J. R. Firth (1957: 194–195; 1968: 181–183; see Östman a...

The Semantic Knowledge-base of Contemporary Chinese (SKCC) is a large scale Chinese semantic resource developed by the Institute of Computational Linguistics of Peking University. It provides a large amount of semantic information such as semantic hierarchy and collocation features for 66,539 Chinese words and their English counterparts. Its POS and semantic classification represent the latest ...
