“…As previously explained, the analysis of the data was done by applying the taxonomy from Chen et al, (2005). The taxonomy is beneficial to describe the common gratitude strategies as well for the explanation of the common gratitude strategy realized by Indonesian female and male EFL learners.…”

The goal of this study is to depict the gratitude strategies utilized by Indonesian EFL female and male students in responding to various academic situations. The data were gathered from 85 undergraduate students of English Literature, Faculty of Cultural Studies, Brawijaya University in Malang using Discourse Completion Tasks (DCT) from O’Keeffe, Clancy, & Adolphs (2011). The results show the diversity of gratitude strategies based on Chen, Ho, & Yang's (2005) taxonomy and used by the participants from both genders, varied from brief, lengthy, to complex thanking acts. All participants delivered mixed sets of thanking speech acts, explained in the following conditions: a) social status (students and lecturers), b) indebtedness (lending money to students), c) breaking promises (coming late to presentations), d) between friends (attending the proposal seminar) and e) the setting of public area (letting students to enter the elevator first). It is also revealed that both genders were successfully expressed their gratitude in responding to the five academical contexts made by the researcher.

“…Since SVM has presented superior performance in classification problems [Dumais et al 1998;Joachims 1998;Yang and Liu 1999;Rennie and Rifkin 2001], many related studies have also adopted the SVM classifiers with different strategies to extract the implicit information and improve the integration accuracy. These SVM-based integration approaches include a cross-training technique for SVM classifiers (SVM-CT) [Sarawagi et al 2003], a topic restriction strategy (SVM-TR) [Tsay et al 2003], a cluster shrinkage approach (CS-TSVM) [Zhang and Lee 2004a], and an iterative approach with pseudo-relevance feedback (SVM-IA) [Chen et al 2005]. Most of these approaches employing the SVM classifiers were found to have higher accuracy then ENB.…”

“…The most important approach, called ENB, enhances the Naive Bayes classifiers with implicit source information. Other state-of-the-art approaches, including Support Vector Machines (SVMs) [Sarawagi et al 2003;Tsay et al 2003;Zhang and Lee 2004a;Chen et al 2005;Chen et al 2006;Ho et al 2006] and the Maximum Entropy model [Wu et al 2005], have been also presented to elevate the performance of Web catalog integration, and they further outperform the ENB approach.…”

Web catalog integration has become an integral aspect of current digital content management for Internet and e-commerce environments. The Web catalog integration problem concerns integration of documents in a source catalog into a destination catalog. Many investigations have focused on flattened (one-dimensional) catalogs, but few works address hierarchical Web catalog integration. This study presents a hierarchical catalog integration (EHCI) approach based on the conceptual thesauri extracted from the source catalog and the destination catalog to improve performance. Experiments involving real-world catalog integration are performed to measure the performance of the improved hierarchical catalog integration scheme. Experimental results demonstrate that the EHCI approach consistently improves the average accuracy performance of each hierarchical category.

“…The enhanced Naïve Bayes classifier (ENB) is shown to have more than 14% accuracy improvement on average. The work in Chen et al (2005) also has the similar concept in its iterative pseudo relevance feedback approach. As reported in Chen et al (2005), the enhanced SVM classifiers consistently achieve improvement.…”

In recent years, the hierarchical taxonomy integration problem has obtained considerable attention in many research studies. Many types of implicit information embedded in the source taxonomy are explored to improve the integration performance. The semantic information embedded in the source taxonomy, however, has not been discussed in previous research. In this paper, an enhanced integration approach called SFE (Semantic Feature Expansion) is proposed to exploit the semantic information of the category-specific terms. From our experiments on two hierarchical Web taxonomies, the results show that the integration performance can be further improved with the SFE scheme.
