MFV-Class: a multi-faceted visualization tool of object classes

Classes are key software components in an object-oriented software system. In many industrial OO software systems,there are some classes that have complicated structure and relationships. So in the processes of software maintenance,testing,software reengineering,software reuse and software restructure,it is a challenge for software engineers to understand these classes thoroughly. This paper proposes a class comprehension model based on constructivist learning theory,and implements a software visualization tool(MFV-Class)to help in the comprehension of a class. The tool provides multiple views of class to uncover manifold facets of class contents. It enables visualizing three object-oriented metrics of classes to help users focus on the understanding process. A case study was conducted to evaluate our approach and the toolkit.     

Institutionalized incentives for ingenuity—Patent value and the German Employees’ Inventions Act

Germany is one of few countries in which the monetary compensation for inventors is not only determined by negotiations between employer and employee-inventor, but also by relatively precise legal provisions. In this paper, we describe the characteristics of the German Employees’ Inventions Act (GEIA) and discuss which incentives it creates. We rely on responses from a recent survey of 3350 German inventors to test hypotheses regarding this institution. We conclude from our data that the law creates substantial monetary rewards for productive inventors. The qualitative responses from our survey confirm this view, but also point to a number of dysfunctional effects.

社会交往的特征及其精神生产力功能

长期以来,学术界往往把人与人之间的社会交往仅仅归之于生产关系,而很少重视其生产力功能。实际上,交往作为一种社会实践活动不论从物质层面还是从精神层面上说都具有生产力功能。本文运用马克思主义的社会交往理论,主要从精神交往这个层面上就社会交往在语言传播、文明成果延续共享、促进人类社会发展等方面论述了社会交往的精神生产力功能,从而突出了现代社会交往所具有的空前重要的生产力意义。

基本路径测试方法之圈复杂度计算

软件测试是软件开发过程中不可缺少的重要组成部分,贯穿整个软件开发过程。在软件测试方法中,白盒测试和黑盒测试是经常使用的测试技术。白盒测试中的基本路径测试方法是解决复杂路径测试最有效的方法,而圈复杂度的计算则是基本路径测试方法中非常重要的环节。实践经验表明,圈复杂度和程序可能存在的缺陷数量有着很大的相关性,本文就基本路径测试方法中如何正确计算圈复杂度进行了探讨。     

PVE: A log parsing method based on VAE using embedding vectors

Log parsing is a critical task that converts unstructured raw logs into structured data for downstream tasks. Existing methods often rely on manual string-matching rules to extract template tokens, leading to lower adaptability on different log datasets. To address this issue, we propose an automated log parsing method, PVE, which leverages Variational Auto-Encoder (VAE) to build a semi-supervised model for categorizing log tokens. Inspired by the observation that log template tokens often consist of words, we choose common words and their combinations to serve as training data to enhance the diversity of structure features of template tokens. Specifically, PVE constructs two types of embedding vectors, the sum embedding and the n-gram embedding, for each word and word combination. The structure features of template tokens can be learned by training VAE on these embeddings. PVE categorizes a token as a template token if it is similar to the training data when log parsing. To improve efficiency, we use the average similarity between token embedding and VAE samples to determine the token type, rather than the reconstruction error. Evaluations on 16 real-world log datasets demonstrate that our method has an average accuracy of 0.878, which outperforms comparison methods in terms of parsing accuracy and adaptability.
