Key Performance Indicators in the Process of Performance Evaluation Selected Approaches
Get PDFPerformance management at individual level requires a systematic approach for evaluating the work and expectations, supporting such efforts of employees by providing evaluation and feedback in the form of the subsequent implementation of the appropriate corrections, while rewarding. One of the strategic assessment tools of performance management in organizations are key performance indicators (KPI) and the underlying assumption that the selected indicators can be measured or quantified. However, the fundamental problem of any performance measurement system is it´s correct assessment. Based on this interpretation, the aim of the article is to analyze the statistically significant association between the application of performance evaluation methods in terms of the degree of KPIs implementation in organizations. For the purposes of assessing the afore mentioned relationship we have specified a set of fourteen most used evaluation methods which were then subjected to testing by Chi-square test of independence, which has been applied. To simplify and reduce the original amount of data, while maintaining a substantial part of the information, the analysis applied the multivariate statistical method of factor analysis. The research sample consists of small, medium and large organizations operating at the local, but also multinational level. The examined relationship was verified. Based on this, it can be stated that we need KPIs to make a complex picture of what organizations really need and how to achieve the set objectives
Sentiment Ranking for Opinion Extraction by Weighted Feature Scheme
Get PDFAbstract— Sentiment Analysis is the analysis of emotions and opinions in a given text using Natural Language Processing. It helps in understanding the user attitude and feelings by analyzing reviews/comments posted by people through social media, blogs etc. Internet availability has given us an easier way of accessing the information and expressing our opinions on various topics or products. These reviews are of immense importance to the targeted organization since they largely affect the outlook of the organization. People tend to consider these reviews when purchasing or using a product. This paper aims to analyze the user's sentiment in the form of free text by extracting the opinionated or sentiment words from the sentences using various techniques. They are further classified into positive or negative sentiment words and are grouped under various categories using a sentiment dictionary based on which every word will be assigned a weight. The major refinement in the proposed system is the estimation of different feature weights for evaluation of overall sentiment score and this increases the accuracy by a huge margin. The average of all the values is computed and the review is rated on a scale of 1 to 5 indicating the sentiment of the user. The sentiment score in addition to providing the user feedback also gives us an insight into the various features and helps an enterprise to focus on improving the below average features to boost the product on the whole

Electrical and Structural Properties of PVDF/Mgo (7%) Nanocomposites Thin Films at Various Annealing Temperatures
Get PDFAbstract—Poly (vinylideneflouride)/nano-magnesium oxide (PVDF/MgO) film with 7% MgO loading percentage was annealed at various annealing temperatures ranging from 70°C to 150°C. The PVDF/MgO thin film was fabricated using spin coating technique with a metal-insulator-metal (MIM) configuration. The dielectric and electric properties of PVDF/MgO with respect to annealing temperatures was studied. The PVDF/MgO nanocomposites thin films annealed at temperature of 70°C (AN70-PVDF/MgO) showed an improvement in the properties; dielectric constant value of 26 at 1 kHz frequency compared to un-annealed sample (UN-PVDF/MgO), which is 21 at the same frequency. As the annealing temperatures were increased from 90°C (AN90) to 150°C (AN150-PVDF/MgO), the dielectric constant values were found to gradually decreased from 25 to 12 respectively, which was lower than the UN-PVDF/MgO thin films. AN70-PVDF/MgO also produced relatively low tangent loss (tan δ). The resistivity value of AN70-PVDF/MgO was also found to increase from 3.08x104 Ω.cm (UN- PVDF/MgO) to 4.55x104 Ω.cm. The increased in the dielectric constant, with low tangent loss and high resistivity value suggests that 70°C was the favorable annealing temperature for PVDF/MgO film suitable for the application in electronic devices such as low frequency capacitor
