Objective measures are favored and widely used by many researchers in evaluating the quality of noise-suppressed speech. A good and reliable objective measure should have property that it could evaluate speech quality in consistent and well correlated with subjective ratings. In this paper, several widely used objective measures are applied to the speech signals with the Chinese languages including Mandarin and Cantonese. The correlations between objective measure outputs and perceptual-subjective ratings are reported and analyzed. The experimental results show that the correlation with the language types of Mandarin and Cantonese are lower than the one with English and objective measures behave differently in Mandarin, Cantonese and English. Detail discussion and conclusion are presented as well.

Conventional content-based filtering methods recommend documents based on extracted keywords. They calculate the similarity between keywords and user interests and return a list of matching documents. In the long run, this approach often leads to overspecialization and fewer new entries with respect to a user's preferences. Here, we propose a semantic recommender system using Linked Open Data for the user profile and adding semantic annotations to the index. Linked Open Data allows recommendations beyond the content domain and supports the detection of new information. One research area with a strong need for the discovery of new information is biodiversity. Due to their heterogeneity, the exploration of biodiversity data requires interdisciplinary collaboration. Personalization, in particular in recommender systems, can help to link the individual disciplines in biodiversity research and to discover relevant documents and datasets from various sources. We developed a first prototype for our semantic recommender system in this field, where a multitude of existing vocabularies facilitate our approach.

Coordinating a software project across distances is challenging. Even without geographical and time zone distances, other distances within a project can cause communication gaps. For example, organisational and cognitive distances between product owners and development-near roles such as developers and testers can lead to weak alignment of the software and the business requirements. Applying good software development practices, known to enhance alignment, can alleviate these challenges. We present a theoretical model called the Gap Model of how alignment practices affect different types of distances. This model has been inductively generated from empirical data. We also present an initial version of a theory based on this model that explains, at a general level, how practices affect communication within a project by impacting distances between people, activities and artefacts. The presented results provide a basis for further research and can be used by software organisations to improve on software practice.
