Community detection is key to understand the structure of complex networks. However, the lack of appropriate evaluation strategies for this specific task may produce biased and incorrect results that might invalidate further analyses or applications based on such networks. In this context, the main contribution of this paper is an approach that supports a robust quality evaluation when detecting communities in real-world networks. In our approach, we use multiple strategies that capture distinct aspects of the communities. The conclusion on the quality of these communities is based on the consensus among the strategies adopted for the structural evaluation, as well as on the comparison with communities detected by different methods and with their existing ground truths. In this way, our approach allows one to overcome biases in network data, detection algorithms and evaluation metrics, thus providing more consistente conclusions about the quality of the detected communities. Experiments conducted with several real and synthetic networks provided results that show the effectiveness of our approach.

Quality Measurements

The point of this survey is to feature issues in information quality research and to talk about potential research chance to accomplish high information quality inside an association. The survey received deliberate writing audit technique in view of research articles distributed in diaries and gathering procedures. Here built up an audit technique in light of particular subjects, for example, ebb and flow inquire about territory in information quality, basic measurements in information quality, information quality administration model and approaches and information quality evaluation strategies. In light of the audit methodology, here select pertinent research articles, concentrate and amalgamation the data to answer an examination questions. The survey features the headway of information quality research to take after its genuine application and talk about the accessible hole for future research. Research territory, for example, association’s administration, information quality effect towards the association and database related specialized answers for information quality overwhelmed the early years of information quality research. Be that as it may, since the Web is presently occurring as the new data source, the rising of new research regions, for example, information quality evaluation for web and huge information is unavoidable. This audit additionally recognizes and talks about basic information quality measurements in association, for example, information fulfillment, consistency, exactness and convenience. Likewise think about and feature holes in information quality administration model and procedures. This survey is critical to feature and break down restriction of existing information quality research identified with the current needs in information quality, for example, unstructured information sort and enormous information.

ntroduction: Detection and examination of proper number of lymph nodes in patients after rectal resection is important for next treatment and management of patients with rectal carcinoma. There are no clear guideliness for minimal count of lymph nodes, variant recommendations agree on the number of 12 (10−14) nodes. There are situations, when is not easy to reach this count, mainly in older age groups and in patients after neoadjuvant, especially radiation therapy. As a modality for improvement of lymph nodes harvesting seems to be establishing of defined protocols originally designed for mesorectal excision quality evaluation. Methods: The investigation group was formed by patients examined in 2 three-years intervals before and after implementation of the protocol. Elevation in count of harvested lymph nodes was rated generaly and in relation to age groups and gender. Results: The average count of lymph nodes increased from 10 to 15 nodes, in subset of patients whose received neoadjuvant therapy from 7 to al- most 14 nodes. The recommended number of lymph nodes was obtained in all investigated age groups. By the increased number of lymph nodes, rises also possibility of positive nodes found, that can lead to upstaging of the disease, in subset of patients whose received neoadjuvant therapy it is more than 4%. Conclusion: Our conclusions show, that forming of multidisciplinary cooperative groups (chiefly surgeon-pathologist), implementation of defined protocol of surgery, specimen manipulation and investigation by detached specialists lead to benefit consequences for further management and treatment of the patients with colorectal cancer.
