Abstract

Purpose

The aim of this paper is to present an online framework for building a domain taxonomy, called TaxoLine, from Web documents automatically.

Design/methodology/approach

TaxoLine proposes an innovative methodology that combines frequency and conditional mutual information to improve the quality of the domain taxonomy. The system also includes a set of mechanisms that improve the execution time needed to build the ontology.

Findings

The performance of the TaxoLine framework was applied to nine different financial corpora. The generated taxonomies are evaluated against a gold-standard ontology and are compared to state-of-the-art ontology learning methods.

Originality/value

The experimental results show that TaxoLine produces high precision and recall for both concept and relation extraction than well-known ontology learning algorithms. Furthermore, it also shows promising results in terms of execution time needed to build the domain taxonomy.

Abstract

In this paper, we describe a novel approach for ontology distribution in ubiquitous environments. We present the Context Aware Explorer (CAE) framework we have developed which allows building context aware applications. Our approach, while built upon Web Ontology Language OWL and RDF Schema, is aiming at modeling context ontology for supporting context reasoning and the design of a Smart Rule Engine that maintains a shared model of context for all computing entities in the smart space. The CAE main contribution is its ability to distribute ontology based on abstract parameters related to situation and to user profile. The ultimate goal is to decrease the response time of the reasoning engine with regards to reasoning accuracy. We also describe the implementation of CAE, and its associated ontology, in a prototype demonstrator of smart environment handling indoor and outdoor context aware services. The validation of the ontology distribution approach was applied to assistive environment dedicated to people having motor disabilities and tested within laboratory conditions. Preliminary performance results are presented to highlight the impact of distributed ontology concept.

The authors examine whether managers switch from artificial income smoothing using discretionary accruals to real income smoothing around corporate governance reform in Egypt.

Abstract

Purpose

The authors examine whether managers switch from artificial income smoothing using discretionary accruals to real income smoothing around corporate governance reform in Egypt.

Design/methodology/approach

The sample comprises 61 non-financial companies listed on the Egyptian Stock Exchange for the years 2004–2011. The authors use discretionary accruals as a proxy for artificial income smoothing and income/loss from asset sales as a proxy for real income smoothing.

Findings

The authors offer a significant contribution to accounting literature by providing new empirical evidence on the trade-off between real smoothing technique (e.g. income/loss from asset sales) and discretionary accruals around governance reform in a developing country.

Research limitations/implications

This study suffers from some limitations. First, the study sample is limited to only 338 observations. However, this is due to collecting the data manually and to the small number of listed firms during the study period. Second, the study period ended in 2011 due to the unprecedented political instability after the 2011 Egyptian people revolution. Third, although this study examines the effect of corporate governance, not all the governance aspects have been examined in the study models due to the lack of data.

Practical implications

First, the results of the total samples reveal that managers prefer real income smoothing than accruals income smoothing. This result may confirm the literature arguments on the advantages of REM methods over AEM methods. Cohen et al. (2008) find that firms switch to manage earnings using REM methods and explain that REM methods are harder to detect because they depend on operating decisions (Schipper, 1989). REM can be undertaken anytime during the year (Gunny, 2010). Besides, REM could not be deemed a violation of accounting standards or regulations (MyVay, 2006).

Originality/value

The authors offer a significant contribution to accounting literature by providing new empirical evidence on the trade-off between real smoothing technique (e.g. income/loss from asset sales) and discretionary accruals around governance reform in a developing country.

Abstract

Purpose

This study aims at examining the level of risk of disclosure practices and the effect of four board of directors' characteristics (board size, board meetings, CEO duality and board expertise) on these practices in the Jordanian context. This study also adds to the body of literature by examining the moderating effect of family ownership on the relationship between the board of directors' characteristics and the corporate risk disclosure.

Design/methodology/approach

The sample of this study contains the non-financial Jordanian firms listed on Amman Stock Exchange (ASE). 376 annual reports of the sampled firms over four years from 2014 to 2017 were used. The content analysis approach was used to collect data and to determine the level of risk disclosure by computing the number of risk-related sentences in the annual reporting. To test the study's hypothesis, the random effect model was employed.

Findings

The empirical results show that the total of the risk disclosure sentences for each firm ranges from a minimum value of 2 sentences to a maximum value of 61 sentences, and the mean of CRD is 28 sentences. The results also indicate that the board expertise is positively related with the level of risk disclosure. Conversely, CEO duality has a negative impact on the risk disclosure practices. However, the results failed to support that the board size and the board meetings have a significant effect on the level of risk disclosure. Furthermore, the study demonstrated that the family ownership moderates the relationship between the board of directors and the corporate risk disclosure.

Practical implications

The finding of this study is more likely be useful for many concerned parties, researchers, authorities, investors and financial analysts alike in understanding the current practices of the risk disclosure in Jordan, thus helping them in reconsidering and reviewing the accounting standards and improving the credibility and transparency of the financial reports in the Jordanian capital market.

Originality/value

The current study contributes to the literature of risk disclosure because the previous research has paid little attention to this topic in Jordan. To the best knowledge of the researcher, this study is the first Jordanian study that focuses on examining the relationship between the board of directors' characteristics and the corporate risk disclosure in the non-financial sector. Furthermore, it is the first study that examines the moderating role of family ownership on such relationships. Consequently, the results of the current study draw attention to the CRD practices and the monitoring role of board of directors in Jordan.
