Pre-trained neural language models give high performance on natural language inference (NLI) tasks. But whether they actually understand the meaning of the processed sequences is still unclear. We propose a new diagnostics test suite which allows to assess whether a dataset constitutes a good testbed for evaluating the models' meaning understanding capabilities. We specifically apply controlled corruption transformations to widely used benchmarks (MNLI and ANLI), which involve removing entire word classes and often lead to non-sensical sentence pairs. If model accuracy on the corrupted data remains high, then the dataset is likely to contain statistical biases and artefacts that guide prediction. Inversely, a large decrease in model accuracy indicates that the original dataset provides a proper challenge to the models' reasoning capabilities. Hence, our proposed controls can serve as a crash test for developing high quality data for NLI tasks.

With the rapid growth of the size of the data stored in the cloud systems, the need for effective data processing becomes critical and urgent. This research introduces a study of the most important characteristics of databases management systems: H ive, SQLMR, and MariaDB Galera. Hive is a cloud database management system. SQLMR is a hybrid system, which depends on the integration between the cloud and traditional systems capabilities. While MariaDB Galera is a traditional database management system developed to cope with the cloud characteristics. In this research, we show the most important developments that have been on those systems, and then we compare their performance in data processing based on the execution time of query operations with the change of the volume of data. That is to identify the performance of those systems practically and to know the developing requirements for access to optimized data management system, and to help users in the selection of the database system that achieves their requirements in terms of availability and scalability.
We present a generic method to compute thefactual accuracy of a generated data summarywith minimal user effort. We look at the prob-lem as a fact-checking task to verify the nu-merical claims in the text. The verification al-gorithm assumes that the data used to generatethe text is available. In this paper, we describehow the proposed solution has been used toidentify incorrect claims about basketball tex-tual summaries in the context of the AccuracyShared Task at INLG 2021.

Data in general encodes human biases by default; being aware of this is a good start, and the research around how to handle it is ongoing. The term bias' is extensively used in various contexts in NLP systems. In our research the focus is specific to biases such as gender, racism, religion, demographic and other intersectional views on biases that prevail in text processing systems responsible for systematically discriminating specific population, which is not ethical in NLP. These biases exacerbate the lack of equality, diversity and inclusion of specific population while utilizing the NLP applications. The tools and technology at the intermediate level utilize biased data, and transfer or amplify this bias to the downstream applications. However, it is not enough to be colourblind, gender-neutral alone when designing a unbiased technology -- instead, we should take a conscious effort by designing a unified framework to measure and benchmark the bias. In this paper, we recommend six measures and one augment measure based on the observations of the bias in data, annotations, text representations and debiasing techniques.
